Abstract:
A low cost, robust, wireless sensor that provides an extended period of operability without maintenance is described. The wireless sensors are configured to communicate with a base unit or repeater. When the sensor unit detects an anomalous ambient condition (e.g., smoke, fire, water, etc.) the sensor communicates with the base unit and provides data regarding the anomalous condition. The sensor unit receives instructions to change operating parameters and/or control external devices.

Abstract:
An irrigation system comprises sprinkler heads with an electrically configurable spray pattern, moisture sensors, and a controller. Based upon input signals from the moisture sensors, the controller dynamically configures the spray pattern of the sprinkler head to allow more water to fall on areas that need to be watered and less water to fall on areas that do not require additional water. The irrigation system can additionally comprise fire sensors. Based upon input from the fire sensors, the controller activates the sprinklers.
Abstract:
A computer-aided training and management system that uses a computer or other processor in wireless communication with an instrumented dog collar and/or optionally, one or more dog interaction devices, such as, for example, video monitors, loudspeakers, video cameras, training toys (e.g., ball, bone, moving toy, etc.), an animatronics “trainer,” a treat dispenser, a food dispensing and monitoring device, a water dispensing and monitoring device, tracking devices, a dog door, dog-monitoring doghouse, a dog-monitoring dog toilet, is described. In one embodiment, the instrumented dog collar is in two-way communication with a central computer system.
Abstract:
A system for load control in an electrical power system is described, wherein one or more data interface devices are provided to a cooling system. The data interface devices are configured to receive commands for controlling the cooling system. A remote monitoring system, such as a monitoring system operated by a power company or a power transmission company sends one or more commands to the data interfaced devices to adjust loading on the electrical power system. In one embedment, the monitoring system sends shutdown commands. In one embedment, the monitoring system sends commands to tell a compressor in the cooling system to operate in a relatively low-speed mode. In one embedment, the monitoring system sends tell the compressor and/or the cooling system to operate in a relatively low-power mode. In one embodiment, the commands are time-limited, thereby allowing the cooling system to resume normal operation after a specified period of time. In one embodiment, the commands include query commands to cause the cooling system to report operating characteristics (e.g., efficiency, time of operation, etc.) back to the monitoring center.
Abstract:
A sensor system that provides an adjustable threshold level for the sensed quantity is described. The adjustable threshold allows the sensor to adjust to ambient conditions, aging of components, and other operational variations while still providing a relatively sensitive detection capability for hazardous conditions. The adjustable threshold sensor can operate for extended periods without maintenance or recalibration. In one embodiment, the sensor is self-calibrating and runs through a calibration sequence at startup or at periodic intervals. In one embodiment, the adjustable threshold sensor is used in an intelligent sensor system that includes one or more intelligent sensor units and a base unit that can communicate with the sensor units. When one or more of the sensor units detects an anomalous condition (e.g., smoke, fire, water, etc.) the sensor unit communicates with the base unit and provides data regarding the anomalous condition. The base unit can contact a supervisor or other responsible person by a plurality of techniques, such as, telephone, pager, cellular telephone, Internet (and/or local area network), etc. In one embodiment, one or more wireless repeaters are used between the sensor units and the base unit to extend the range of the system and to allow the base unit to communicate with a larger number of sensors.

Abstract:
A system for load control in an electrical power system is described, wherein one or more temperature-monitoring devices are provided to control power service to relatively high-load devices such as, for example, pool pumps, electric water heaters, electrics ovens etc. When ambient temperatures are relatively high, and thus, electrical power demands from air conditioning systems are relatively high, the temperature-monitoring devices can remove power from the controlled device during the hottest portions of the day. The temperature-monitoring devices can provide power to the controlled devices during the cooler portions of the day. During heat waves or other periods of relatively continuous high heat, the temperature-monitoring devices can schedule power to the controlled devices to reduce overall power demands and to run the controlled devices during the cooler portions of the day when air conditioning electrical loads are reduced.
Abstract:
Systems and methods for detecting presence and movement of pests. Various embodiments of a pest detection system can be based on, for example, a beam-interrupt detector or a thermal imaging device. The beam-interrupt detection based system can provide functionalities such as counting of pests crossing a given beam. A plurality of such beams at different heights can also allow distinguishing different sized pests. The thermal imaging based detection system can provide functionalities such as tracking movement of pests. A recording can be triggered by detection of pest movement, thereby improving the efficiency of recording and reviewing information indicative of presence and movement of pests in a monitored area. Movement of pests can be monitored on a passive basis, or by providing a stimulus that induces movement.
Abstract:
The system and method for detecting water and/or gas leaks by monitoring usage patterns is described. In one embodiment, the existence of a leak is detected by looking for usage patterns wherein water or gas is always being used, at least at a low rate. A leak is indicated if usage does not drop to zero, at least for a period of time, during a given time interval (e.g., during a 24-hour period). The severity of the leak is indicated by the minimum amount of usage during the given time period. In one embodiment, the leak detection system is provided in connection with an Automatic Meter Reading (AMR) system.
