  • Publication number: 20160146489
    Abstract: A smart vent comprises a thermoelectric generator coupled to a power storage. The thermoelectric generator that generates voltage or electrical energy based on a temperature differential between a room temperature and a temperature in a duct where the smart vent is installed. The generator charges the storage using the generated voltage. A radio is coupled to the power storage and receives a wireless command from a device to open a vent so that air flows from the duct to the room. A processor, coupled to the storage and the radio, determines if there is sufficient charge in the power storage to open the vent apparatus; sends a command to a motor to open the vent if there is sufficient charge. A motor, coupled to the storage and processor, opens the vent upon receiving the command, thereby ceasing charging the power storage as the temperature differential decreases.

  • Patent number: 6853840
    Abstract: The system comprises a wireless transceiver with a processor for measuring RSSI in received signals. The processor analyzes fade duration or fade frequency in the received signals to determine if the transceiver is moving. If the transceiver is moving, then the processor can send a command to disable a fixed wireless terminal in one embodiment. In another embodiment, if the transceiver is not moving, then the processor can send a command to place a GPS receiver into a power conservation mode.

  • Publication number: 20040019698
    Abstract: A method and system are provided for registering a geolocation and for matching the geolocation with latitude and longitude coordinates based on its geoname. The system functions through the inter-action between satellites, satellite receivers, a computer system, the Internet, to provide a matching system between a given geoname and its geolocation. Users subscribe to a service to have easy access via the Internet to the information received from a server identified as a Universal Geoname Registry that includes in its database the latitude and longitude coordinates, the physical address and other similar attributes. The commonality of each set of coordinates is the geoname, which can henceforth replace conventional addresses. For example, a user logging on to the Internet can access map servers and obtain direction to based on the geoname of a particular geolocation.

  • Patent number: 6625209
    Abstract: A short synchronization time modem comprising a GPS receiver for receiving a broadcasted signal comprising a high precision clock. When a first short synchronization data modem communicates with a second, a PLL in each data modem synchronizes its own local clock to the same high precision clock derived from the same received broadcasted signal. The modems connect for the first time using one of many clock recovery schemes known to the modem designers. Once they disconnect, the modems keep their clocks synchronized using a local GPS receiver and the received broadcasted signal. This prevents the local clock of the modems from drifting, which significantly reduces the time period the modems need to synchronize the next time they connect.

  • Patent number: 6166626
    Abstract: Apparatus and method for a location determination and reporting (LDR) system for clandestinely determining and reporting a missing vehicle present location. The vehicle is equipped with a handheld cellular phone unit and controller that are accepted and held by a cellular phone cradle that can include electrical poster and/or a location determination (LD) unit to determines the LD unit present location. The cellular phone unit can operate on one cellular channel or on two distinct cellular channels. When the vehicle is reported missing, the central station interrogates the vehicle LDR system to determine the vehicle present location. A location interrogation signal is transmitted, commanding the LD unit to transmit its present location. The cellular phone does not signal receipt of an incoming call for an initial time period of selected length .DELTA.td, awaiting possible receipt of a location interrogation signal on the first cellular channel.

  • Patent number: 6038444
    Abstract: Method and apparatus for tracking the location of, and for providing cellular telephone handoff for, a mobile cellphone user as the user moves from one cell to another. A boundary curve B12 between a first cell and an adjacent second cell is defined in an electronic map. First and second quasi-boundary curves QB1 and QB2, lying within the first and second cell, respectively, are defined, where each point on the curve QBi (i=1,2) lies at a selected distance from the boundary curve B12. A common region CR12 of points lying between the quasi-boundary curves QB1 and QB2 and including the boundary curve B12 is defined. The present cellphone location of the cellphone user is determined using a location determination system, such as GPS or GLONASS or a ground-based system. Cellular telephone service for the cellphone user is provided by a first cell site or by a second cell site, when the cellphone user is located within the first cell or the second cell, not including the overlap region CR12.
