Abstract:
A low cost, robust, wireless sensor system that provides an extended period of operability without maintenance is described. The system includes one or more intelligent sensor units and a base unit that can communicate with a large number of sensors. When one or more of the sensors detects an anomalous condition (e.g., smoke, fire, water, etc.) the sensor 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, etc. In one embodiment, one or more wireless repeaters are used between the sensors 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. In one embodiment, each sensor is labeled according to its intended location, and system configuration data containing the sensor identification codes and corresponding sensor locations is provided to the user.
Abstract:
An Electronically-Controlled Register vent (ECRV) that can be easily installed by a homeowner or general handyman is disclosed. The ECRV can be used to convert a non-zoned HVAC system into a zoned system. The ECRV can also be used in connection with a conventional zoned HVAC system to provide additional control and additional zones not provided by the conventional zoned HVAC system. In one embodiment, the ECRV is configured have a size and form-factor that conforms to a standard manually-controlled register vent. In one embodiment, a zone thermostat is configured to provide thermostat information to the ECRV. In one embodiment, the zone thermostat communicates with a central monitoring system that coordinates operation of the heating and cooling zones.

Abstract:
A system for wearable electronics devices configured to intercommunicate through wireless communication and, optionally, to communicate with other electronic devices such as cellular telephones, computers, computer networks, etc. is described. In one embodiment, a communication module receives information from one or more devices and provides audio and, optionally, stimulatory information to the wearer. In one embodiment, an electronic device is provided in a shoe. In one embodiment, a wireless (or wired) earpiece is provided to provide audio information to the user. In one embodiment, the shoe-mounted device includes a display to show time, caller-id information, temperature, pulserate, etc.
Abstract:
A signal repeater for receiving and re-transmitting signals from environmental transducers and the like, and for mechanically and electrically cooperating with existing electrically powered fixtures. More particularly, the present invention includes a housing unit for mechanically and electrically coupling to the powered fixture, a transceiver unit, and a first power supply electrically connected to the transceiver circuit and housed by the housing unit. The repeater is adapted to maintain the functionality of the fixture.
Abstract:
A real-time monitoring system that monitors various aspects of the operation of a refrigerant-cycle system is described. In one embodiment, the system includes a processor that measures power provided to the refrigerant-cycle system and that gathers data from one or more sensors and uses the sensor data to calculate a figure of merit related to the efficiency of the system. In one embodiment, the sensors include one or more of the following sensors: a suction line temperature sensor, a suction line pressure sensor, a suction line flow sensor, a hot gas line temperature sensor, a hot gas line pressure sensor, a hot gas line flow sensor, a liquid line temperature sensor, a liquid line pressure sensor, a liquid line flow sensor. In one embodiment, the sensors include one or more of an evaporator air temperature input sensor, an evaporator air temperature output sensor, an evaporator air flow sensor, an evaporator air humidity sensor, and a differential pressure sensor. In one embodiment, the sensors include one or more of a condenser air temperature input sensor, a condenser air temperature output sensor, and a condenser air flow sensor, an evaporator air humidity sensor. In one embodiment, the sensors include one or more of an ambient air sensor and an ambient humidity sensor.
