DETAILED DESCRIPTION - FIG. 1 illustrates an embodiment of an occupancy sensing system based on some inventive principles of this patent disclosure. The embodiment of FIG. 1 includes a computer workstation 10 and an occupancy sensor 12 organized to monitor an area 14 related to the computer workstation for one or more occupants. The occupancy sensor 12 generates an occupancy signal in response to monitoring the house. A connection 16 between the occupancy sensor and the pc workstation allows the pc workstation 10 to process the occupancy signal and perform one or more power administration capabilities in response to the occupancy signal. A pc workstation (or "computer" or "workstation") refers to a mix of input, output, and computing hardware that can be used for work or leisure by a person, and contains desktop computers, notebook computer systems, terminals related to networks, and many others. The computing hardware may embody a central processing unit (CPU) to execute program directions. The workstation might course of the occupancy signal from the occupancy sensor with software program that uses CPU cycles to carry out its capabilities. Processing the occupancy sign may be performed as a low priority process on the CPU. Implementing the occupancy signal processing as a low precedence process could combine well with different CPU processes as a result of, if the workstation is in use and other larger precedence course of are operating, there isn't any concern that the low priority occupancy sign processing is slowed down. However, if the occupancy sensor is checking for occupancy, then the workstation is unlikely to be in use, and free CPU cycles are available. Furthermore, processing the occupancy sign with workstation CPU cycles may additionally allow the processing energy of the occupancy sensor to be lowered, thereby decreasing its cost. The occupancy sensor 12 has a field of view 18 that enables it to watch the house 14 associated with the computer workstation. The occupancy sensor 12 could also be based on any suitable sensing technology equivalent to passive infrared (PIR), ultrasonic (U/S), audio, video, and so on., or any mixture thereof. FIG. 2 illustrates another embodiment of an occupancy sensing system according to some inventive rules of this patent disclosure. FIG. Three illustrates another embodiment of an occupancy sensing system according to some inventive principles of this patent disclosure. The embodiment of FIG. 3 is just like the embodiment of FIG. 1 but within the embodiment of FIG. 3, the workstation 24 includes performance 26 that permits a user to adjust a parameter of the occupancy sensor at the workstation. The adjustable parameter could embrace a time-out delay, sensitivity setting, and so forth., for the occupancy sensor. The connection 32 may be integral with the connection 16 that carries the occupancy sign, or it could also be a separate connection. FIG. 4 illustrates another embodiment of an occupancy sensing system in line with some inventive rules of this patent disclosure. The embodiment of FIG. 4 is similar to the embodiment of FIG. 2 however the embodiment of FIG. 4 contains load monitoring apparatus 34 that permits the workstation 36 to monitor one or more loads through a connection 38 to the workstation. The load monitoring apparatus 34 may be separate from, or integral with, power switch 20, and enables the workstation to find out power, voltage and/or current levels, as well as on/off standing and different parameters of an electrical load. FIG. 5 illustrates an embodiment of a computer workstation in accordance with some inventive ideas of this patent disclosure. The workstation 42 of FIG. 5 includes a show 44 and a CPU 46. An occupancy sensor forty eight is mounted to the display to facilitate monitoring the space related to the workstation. The occupancy sensor forty eight could also be separate from, or integral with, the display 44, and could also be primarily based on any appropriate sensing know-how. The occupancy sensor forty eight generates an occupancy sign which is transmitted to the CPU forty six by means of a connection 50, which could also be applied with any appropriate wired or wireless connection. FIG. 6 illustrates an exemplary embodiment of a computer workstation according to some inventive principles of this patent disclosure. The workstation fifty four is proven divided into hardware and software parts. As defined above, the working system 56 usually contains inside power management options 88 that can be configured to turn off varied items of hardware to reduce power consumption when the workstation isn't getting used. The interior energy administration options 88 constructed into the operating system work on the assumption that the workstation is no longer in use when no consumer inputs in the form of key presses or mouse movements have been acquired for a predetermined time frame. Basing energy administration selections on the amount of time without user inputs to the workstation, nevertheless, often leads to incorrect assumptions that end in units being turned off and/or the workstation being locked down while the user continues to be current on the workstation. Moreover, if the user does depart the workstation shortly after the last user enter motion, the workstation may be left unattended, absolutely powered, and unsecured throughout your complete time-out periods set for the assorted elements. The application software program 58 could include inside energy management performance 78 that makes decisions in response to the precise presence or absence of a consumer at the workstation somewhat than assumptions primarily based on the amount of time with out user enter actions. The inner energy management functionality 78 determines the state of an occupancy signal from an occupancy sensor 28 by means of a USB port sixty eight and makes use of this info to make selections on when to turn off power to various pieces of hardware, place the workstation in a suspend, sleep or hibernate mode, and/or lock down the workstation and require the consumer to re-enter a password. Using an occupancy sensor to control the interior power management capabilities of a workstation might cut back energy consumption and/or enhance workstation security. For example, occupancy sensors that use ultrasonic sensing expertise are likely to have good sensitivity to the "small motions" which can be typical of an individual working at a desktop, and therefore, could present an accurate indication of the presence of an occupant at a workstation. Subsequently, the timeout delay for the occupancy sensor 28 may be set to a comparatively brief period of time, e.g., a couple of minutes, with out producing false indications of an unoccupied condition on the workstation. This will lead to decreased power consumption and improved safety because the show, exhausting drive and other hardware may be turned off and the workstation locked down shortly after the consumer leaves the workstation. Furthermore, using an occupancy sensor to regulate the inner energy management features of a workstation could scale back or eliminate instances wherein hardware is turned off and/or the workstation locked down regardless that the consumer continues to be current on the workstation. The application software fifty eight can also embrace software to interface the workstation to a lighting control system or other building automation system by means of the network interface card 76 or by any other suitable interface. The person interface software program eighty may additionally enable a user to configure which internal and exterior energy management actions to absorb response to the occupancy sensor 28 equivalent to turning off the show sixty two or laborious drive 64, inserting the workstation in a low power mode comparable to sleep, suspend, hibernate, and so on., locking down the workstation with password protection, turning off switched receptacles in one or more power strips 89 and 90, turning off external equipment with built in energy administration functionality akin to printer 92, or communicating with a lighting management system or other constructing automation system by means of the community interface card. The user interface can also allow the user to configure the appliance software program to show off internal or external hardware instantly upon receiving an unoccupied indication from the occupancy sensor, or after one or more extra time delays. Numerous further time delays could also be used to stagger the times at which completely different pieces of hardware are turned off, as well as when they're turned back on to stop excessive power surges when the presence of a person at the workstation is detected again. The user interface might also enable a consumer to process and/or view the power consumption of the workstation and/or any peripherals having power monitoring capability in actual time, as properly has historical records of energy consumption to look for patterns which will provide indications of how to realize further power financial savings. The consumer interface may enable the user to configure the system to report energy consumption knowledge to a lighting management system or different constructing automation system for further processing and analysis. The appliance software program could also be applied with an software programming interface (API), thereby enabling it to hook, and be hooked by, other software. Some of the applying software program performance may be carried out with a consumer interface that is just like a normal screensaver, and a number of parts of the application software program may be chosen from a screen saver portion of the operating system. Nonetheless, the configuration and other hooks may be explicit to the occupancy sensing and power switching gadgets and their own resident packages. The inventive principles usually are not limited to instance implementation particulars shown in FIG. 6. For example, the connections made by way of the USB ports and NIC may be implemented with wireless connections reminiscent of Bluetooth, or may use alternative wired connections similar to DisplayPort or HDMI connections. Energy line communication (PLC) connections may be used to communicate with power switches in energy strips or in switched receptacles situated in wiring units near the workstation. Furthermore, switched power receptacles could also be integrated directly into the workstation to regulate energy to peripheral gadgets in response to an occupancy sensor that's related to the workstation. FIG. 7 illustrates an embodiment of a dialog field for implementing a person interface according to some inventive ideas of this patent disclosure. The dialog box 94 consists of graphical "slider bars" for setting the sensitivity, field of coverage (when it comes to viewing angle) and time-out delay for an occupancy sensor that's able to receiving adjustable parameters. The dialog field additionally includes verify bins to specify which internally managed hardware similar to shows (displays) and arduous drives, as well as which externally managed hardware akin to energy strips, needs to be turned off in response to the occupancy sensor. FIG. Eight is a block diagram of an embodiment of an occupancy sensor in line with some inventive rules of this patent disclosure. The occupancy sensor 96 includes a number of sensors 98 primarily based on any appropriate sensing expertise or technologies. A controller 100 processes uncooked indicators from the one or more sensors 98 and generates an occupancy sign which is transmitted via a USB port 102. Typical sensitivity and time-out delay controls 104 could also be included to enable the controller to regulate the occupancy sensor for the particular space it's configured to monitor. Alternatively, or additionally, the controller could adjust the occupancy sensor in response to adjustable parameters that it receives via the USB port 102. One or more indicators 106 may be included to display the occupied/unoccupied standing as determined by the occupancy sensor. For example, a tri-colour LED could also be configured to display pink for an unoccupied situation, inexperienced for an occupied condition, and yellow for a fault situation. A "wake now" input permits a consumer to take the system out of unoccupied mode if the sensor doesn't detect when the user returns to the workstation. Electronics within the occupancy sensor or utility software program within the workstation could increase the sensitivity setting of the occupancy sensor each time the wake now button is pressed, since this will likely indicate that the sensitivity setting is simply too low. FIG. 9 is a block diagram of an embodiment of a power strip based on some inventive ideas of this patent disclosure. The facility strip 110 of FIG. 9 receives enter power from a connection 112 which may embrace a plug-and-cord meeting, connector prongs to plug directly right into a receptacle, and so forth. A primary switch and/or circuit breaker and/or surge arrestor 114 receives the input energy which is distributed directly to a first set of receptacles 116 which can be energized when the ability change 114 is closed. The workstation interface 130 allows the facility strip to communicate with a workstation by means of a wired or wireless connection utilizing any appropriate interfacing arrangement. The facility monitor circuit 128 could embody any appropriate circuitry to monitor the voltage, current, energy, and many others., of any load linked to any of the switched or unswitched receptacles. In some embodiments, a commercially out there meter chip could also be used along with a current sense transformer and voltage sense leads to offer a low-value solution that could be simply built-in into the ability strip. The person interface 126 may include any type of inputs and/or outputs to enable a person to configure and/or management the power strip, enter parameters, examine the status or efficiency historical past of the ability strip, etc., from the facility strip itself. The user interface may include one or more enter gadgets reminiscent of a potentiometer or other analog enter, digital switches of any sort including DIP switches, toggle switches, rotary switches, and so forth. The user interface might embrace a number of output devices similar to lights, LEDs, numeric shows, alphanumeric shows, dot-matrix displays, etc. The person interface could also be configured to allow a user to set a number of time delays that control the operation of the switching circuit as described below, in addition to communication protocols, and/or additional time delay, and/or another parameters. The communications with the workstation could also be only one-approach to manage one or more units of switched receptacles, or bi-directional to enable reporting of power monitoring knowledge to the workstation. In some embodiments, the controller 124 in the ability strip may be configured to turn each sets of switched receptacles 120 and 122 on or off at the identical time as quickly because it receives a command from the workstation. In different embodiments, the controller might delay turning one in every of the two sets on or off to keep away from power fluctuations, surges, and many others. Alternatively, the completely different units of switched receptacles a hundred and twenty and 122 could also be managed by different commands from the workstation which can embrace logic for staggering load turn-on and switch off, or for controlling the 2 sets of receptacles differently in response to completely different occupancy circumstances on the workstation. For instance, totally different loads could also be turned on or off in response to totally different occupancy sensors in a multi-sensor association as described below. FIG. 10 is a perspective view of an example embodiment of an occupancy sensor in accordance with some inventive rules of this patent disclosure. The embodiment of FIG. 10 may be used, for example, to implement embodiment of FIG. 8. The occupancy sensor of FIG. 10 includes a compact housing 132 to facilitate simple mounting on a workstation display. The front of the housing consists of two ultrasonic transducers 134 and 138 which are mounted on a convex surface to provide an outlined protection pattern (area of "view") for ultrasonic occupancy sensing. A mini USB port 140 allows the usage of a regular USB cable to attach the occupancy sensor to a USB port on the workstation. A removable panel 142 conceals commonplace management dials for sensitivity and time-out delay settings. A pushbutton 144 could also be used to implement the "wake now" function described above. In some embodiments, the protection sample of the occupancy sensor could also be adjusted by disabling one of the transducers, or by offering totally different weighting to the outputs from the transducers to implement a beam forming method. The occupancy sensor of FIG. 10 could also be mounted in any suitable location using any appropriate method reminiscent of clips, magnets, two-sided tape, hook-and-loop fasteners resembling Velcro, and so forth. In some embodiments, a devoted communication cable for connecting to a workstation may be permanently connected to the housing using a pressure relief. Alternatively, or in addition to a USB port or permanent cable, a wireless interface using radio frequency (RF) or infrared (IR) expertise may be included for communication with the workstation. An Infrared Information Association (IrDA) compatible interface 148 is proven in FIG. 10 to implement IR communications. RF communication may be achieved with an antenna that's inner to the housing if the housing is made from plastic. FIG. Eleven is a perspective view of an example embodiment of a energy strip in line with some inventive rules of this patent disclosure. The embodiment of FIG. 11 could also be used, for instance, to implement the embodiment of FIG. 9. The facility strip of FIG. Eleven features a housing 150, a plug-and-cord meeting 152, a foremost energy swap 154, an IrDA receiver 158, and a type-B USB port 156 for connecting the ability strip to a computer or other tools. Two units of receptacles 160 and 162 are de-energized when the primary energy swap 154 is within the OFF place. FIGS. 12 and 13 illustrate a aspect elevation view and a high plan view, respectively, of an instance of the coverage pattern 164 that could be achieved with the occupancy sensor of FIG. 10. The occupancy sensor 131 is mounted to the top of a workstation show 166 that's situated on a desk 168. In this instance, the workstation CPU is included in the display 166 and is managed by keyboard 170. As seen in FIGS. 12 and 13, the coverage sample 164 includes the consumer's chair 172 and different areas related to the workstation that the consumer is more likely to occupy whereas actively working at the workstation. These areas include a printer 174, a activity lamp 176 and an area heater 178. The protection pattern is typical of the sample that could be achieved with a two-transducer ultrasound system. This pattern may be altered by turning off or weighting the outputs from a number of of the transducers as described above, or through the use of different occupancy sensing technologies. FIG. 14 is a top plan view of a workspace related to one other embodiment of a workstation occupancy sensing system based on some inventive ideas of this patent disclosure. The workspace of FIG. 14 is an office having a door 180, a desk 182, a chair 184 for the workplace's foremost occupant, customer chairs 186, and a whiteboard 187. A workstation show 188 has two occupancy sensors 190 and 192 that are mounted on top of the show and linked to the workstation by USB cables or other kinds of connections as described above. The first occupancy sensor 190 has a protection sample 194 that is mostly intended to include solely the house that is prone to be occupied by the main occupant of the workplace while working alone. Each of the occupancy sensors 190 and 192 could also be related to the workstation and configured and operated as described in the context of techniques having a single occupancy sensor as described above, but with separate settings and actions outlined for each occupancy sensor. For instance, room lighting or house heating within the office perhaps turned on in response to either of the 2 occupancy sensors detecting an occupied situation, whereas the display, and any process lighting, printer, or different peripherals situated on the desk 182 might solely be controlled in response to the occupancy sensor 190 having the protection sample 194 that includes the desk area. FIG. 15 illustrates another embodiment of an occupancy sensing system according to some inventive ideas of this patent disclosure. The embodiment of FIG. 15 consists of a number of workstations 200, every workstation having an occupancy sensor 202 connected to the workstation utilizing any of the strategies described above. Each workstation additionally has at the least one constructing gentle fixture 204 that illuminates the space related to the corresponding workstation. The circulation of energy to the constructing lights is managed by a load management system 206 in response to commands obtained from a constructing automation server, workstation, or other controller 208. The load management system 206 and building automation or lighting system controller 208 and workstations 200 are related to a constructing network 210 via network adapters 212, 214 and 216, respectively, in addition to their own individual community interface playing cards. The building community 210 could also be carried out with Ethernet, CAN or different type of community appropriate for building automation, energy administration, and many others. The load management machine could also be implemented with a relay cabinet, dimmer rack, distributed relay/dimmer system, and many others., or any other network related load control gadget. The constructing automation controller 208 provides the overall operational logic for the system. When the controller 208 receives a message from one of many workstations indicating that the related occupancy sensor has detected an unoccupied situation for the related space, it points a command to the relay cabinet instructing it to show off the sunshine for the area associated with that workstation. Upon receiving a sign from a workstation that the related space is as soon as once more occupied, the controller alerts the relay cabinet to revive power to the light for that space. A potential advantage of the system illustrated in FIG. 15 is that it may allow lighting and other building automation methods to better accommodate occupants in cubicles or other comparatively small areas. Traditional lighting control methods and different building automation systems typically make use of ceiling or wall mounted occupancy sensors. Cubical spacing requires extra densely positioned sensors with proper alignment sophisticated by the situation of overhead lighting fixtures, heating ventilation and air conditioning (HVAC) tools, sprinklers, and many others. Furthermore, the frequent rearrangement that's frequent with cubical spaces presents a further challenge to proper alignment of occupancy sensors. The inventive principles referring to workstation-primarily based occupancy sensor programs described in this patent disclosure, nonetheless, could reduce or eradicate these issues as a result of the occupancy sensor for every workstation and its associated workspace may be positioned very easily in a detailed location that reliably displays the world most more likely to be occupied by the workstation person. Moreover, the inventive principles could reduce the price and uncertainty related to mounting numerous occupancy sensors on ceilings or partitions of buildings. In embodiments during which a workstation is networked to a lighting control system or different building automation system, the application software program may implement a blink warning override function. For instance, the lighting control system may be configured to show off the lights in a building area in response to a timer-based mostly vitality conservation schedule. In such a configuration, the lighting control system usually turns the lights off briefly (a "blink warning") prior to truly turning off the lights to notify occupants of the impending automated turn-off. After the blink warning, the lights are held on long sufficient to permit occupants to go away the world or enter a request to the lighting management system to maintain the lights on. Inputting a request usually requires the occupant to discover a control station for the lighting management system. The nearest management station may be a substantial distance from the occupant's workstation. In keeping with some inventive ideas of this patent disclosure, the appliance software could mechanically notify the lighting management system that the space associated with the workstation is occupied, and subsequently, robotically override the blink warning for the sunshine or lights that illuminate the area associated with the workstation. Alternatively, or as well as, the appliance software could receive a message from the lighting control system when a blink warning is imminent, and present a pop-up message or dialog field to the occupant advising the occupant of the impending blink warning. This may occasionally merely notify the occupant of the blink warning event, or the occupant may then be allowed to elect through the workstation to override the blink warning, or to permit the blink warning to proceed as regular. In embodiments wherein a workstation is networked to a lighting control system or other building automation system, the applying software program can also provide different override options. For instance, if the lighting management system is configured to show off the lights in a building space in response to a timer-based mostly vitality conservation schedule, the application software might request that the lighting management system maintain the lighting in the house related to the workstation, no matter any blink warn functionality. The maintained lighting might include not only the area associated with the workstation, but in addition any related areas to allow for egress from the area. The application software may also be configured to permit or override an attempt by a networked building automation system to sweep off energy receptacles within the area related to the workstation if the occupancy sensor indicates that the house is occupied. The sweep-off performance may be built-in with, or separate from the blink warning override functionality. In embodiments through which a workstation is networked to a lighting management system or different building automation system, the application software program can also provide load monitoring knowledge to the management or automation system if there may be any load monitoring apparatus linked to the workstation. This may occasionally enable the lighting control system or different building automation system to guage the effectiveness of the occupancy sensing and cargo management performance of the workstation-primarily based occupancy sensing techniques, in addition to their interplay with other building automation techniques. In areas the place a handheld or different distant control is used for native control of lights in a lighting management system or other building automation system, a workstation having an occupancy sensor connected may be additional linked to the remote management as a approach to interface the workstation to the control or automation system. For example, an existing handheld distant control might provide on/off and dimming management of overhead lights by means of an IR receiver in a digital wall change or photocell device. An extra wired or wireless connection may be created between the handheld remote and the workstation to allow the workstation to manage the lighting in response to the occupancy sensor by the handheld remote, thereby eliminating the need for a network connection between the workstation and the lighting control system or constructing automation system. Alternatively, a wireless connection may be created directly between the workstation and the receiver that is used by the handheld remote, thereby permitting the workstation to communicate straight with the lighting management system by way of the prevailing system parts and without the necessity for an extra network connection. The methods and apparatus described above allow the implementation of numerous features according to the inventive principles of this patent disclosure. Some instance implementation details are described below to illustrate the numerous options and advantages which may be realized. The inventive rules, nonetheless, will not be limited to those instance particulars. Although any suitable occupancy sensing technology, or mixture thereof, may be utilized, ultrasonic sensing could also be significantly well suited to the small areas and small movement which will should be detected for occupants performing office work in a cubicle. Mounting the one or more occupancy sensors on a workstation show might present ideally suited converge because workstation users typically arrange their complete workspace around the display. Utilizing an occupancy sensor that generates a traditional occupancy sign that gives a binary occupied/unoccupied indication could simplify implementation and allow the use of existing occupancy sensing circuitry which has been subjected to intensive troubleshooting, high-quality tuning and price reduction. However, different types of occupancy sensors that provide extra raw output such because the unprocessed output from an ultrasound transducer or infrared pyrometer may be used, and the computing power of the workstation could also be used to course of the raw output to make the occupied/unoccupied willpower. The occupancy sensors could embody onboard electronics which might be only adequate to regulate the sensitivity and time-out delay based mostly on local inputs on the occupancy sensor, or the electronics could also be in a position to adjust the occupancy sensor in response to adjustable parameters which can be enter by a workstation user via a pop-up or management panel and transmitted by means of a USB or other wired or wireless connection. Power strips having multiple switched and unswitched energy receptacles may provide an excellent platform to modify energy to exterior workstation peripherals such as activity lighting, printers, area heaters, etc., in response to an occupancy sensor coupled to the workstation. Nonetheless, different power switching platforms could also be used together with single-receptacle plug-in modules that plug straight into a wall outlet with no power cord and communicate with the workstation via a wired or wireless connection comparable to a Bluetooth wireless interface. Other examples embrace building wiring units comparable to wall outlets which have switched receptacles and talk with the workstation via a wired or wireless connection. One sort of energy strip could embody a USB connection to the workstation with a mixture of switched and unswitched receptacles as shown in FIGS. 9 and 11. Another sort of receptacle could not have a connection to the workstation, however as a substitute may be connected directly to the occupancy sensor by a wired or wireless connection. Such an embodiment could have in-built sensitivity and time-out delay functionality and should embrace user inputs to regulate these parameters. In embodiments in which a workstation could also be placed in a standby or hibernate mode when the area associated with the workstation is unoccupied, the ability for the USB or different connection to the occupancy sensor could also be turned off. Therefore, the workstation operating system might need to be configured to wake when it receives a signal on the USB or different connection. The inventive principles of this patent disclosure have been described above with reference to some particular instance embodiments, but these embodiments might be modified in arrangement and detail without departing from the inventive concepts. For example, some of the embodiments described above are illustrated in the context of lighting control methods, however the inventive rules could also be applied to HVAC techniques, security techniques, and so on. As an extra example, a lot of the performance in the embodiments described above is described in the context of a software program implementation, but any of the functionality could even be implemented with analog and/or digital hardware, software program, firmware, or any appropriate combination thereof. Such adjustments and modifications are thought of to fall throughout the scope of the following claims.
