  • Patent number: 6718164
    Abstract: A communication device (100, 200) capable of transmitting information provides the means for regulating the temperature (116) of one or more heat-sensitive modules or components (160) of the communication device through the adaptive and dynamic control of the flow of transmissions by the communication device, thereby eliminating the need for stored thermal profiles of heat-sensitive modules of the communication device. In addition to the heat-sensitive module(s), the communication device has a multi-logic controller block (110) and a transmission flow control block (140). The multi-logic controller block (110) receives the temperature of the heat-sensitive module (116) and a first control clock (112) and utilizes multi-value logic to generate a flow control signal having hysteresis (126).

  • Patent number: 5729539
    Abstract: A transceiver (107) operates in a TDMA communication system (100) with a primary server (102) and at least one other potential server (103). The transceiver (107) has defined transmit slots and defined receive slots for communication with the primary server. Mandatory transmit slots are identified from among the defined transmit slots according to a particular specification. The transceiver schedules signal quality measurements for the potential server based at least in part on the particular specification for identifying mandatory transmit slots (400).

  • Patent number: 5150031
    Abstract: A battery charging unit communicates with an operational device while contemporaneously charging a battery to power the device. The device provides information to the charging unit indicating its present operational status, which enables the charging unit to determine the magnitude of the proper charging current under such operating conditions. In this way, battery life is maximized while battery charging time is minimized.

  • Patent number: 4430755
    Abstract: A system for radio-telephone communication between a user at a remote location and the commercial telephone system or between two users at remote locations comprises a fixed terminal that is connected by wire lines or the like to the commercial telephone system and a plurality of portable radio units. The terminal is equipped for duplex operation on a plurality of channels, each of which uses separate frequency bands for transmitting and receiving. Each of the portable units is a simplex transceiver adapted to receive on each of the frequencies of transmission from the terminal and to broadcast on each of the frequencies received by the terminal. The terminal places a channel acquisition tone on an unused channel that is the next to be used. The terminal calls portable unit by shifting channel acquisition tone to another channel and broadcasting an identifier to the portable unit.

  • Patent number: 4141351
    Abstract: A circuit for checking a plurality of impedances having a common connection point as for use in an emergency medical ratio, where the impedance of each ECG electrode contact is automatically and sequentially checked during the initial calibration transmission, using the AC non-polarizing signal which is also used as the ECG subcarrier for the medical data telemetry. The ECG telemetry calibration signal is also processed to provide a sequential switching control. Poor electrode contacts are indicated visually to the paramedic in charge and thus can be corrected before ECG telemetry begins.
