  • Patent number: 6720864
    Abstract: A wireless communication device (32) within a wireless on-call communication system (10) includes a device receiver (92) for receiving an on-call message (36), a device processor (98) coupled to the device receiver (92) for processing the on-call message (36); a device memory (100) coupled to the device processor (98) for storing the on-call message (36); and an on-call application (108) coupled to the device processor (98) having an on-call schedule (80) for defining an active time period (126) and an inactive time period (128). The device processor (98) processes the on-call message (36) during the active time period (126) and discards the on-call message (36) during the inactive time period (128).

  • Patent number: 5381138
    Abstract: A selective call receiver includes receiver circuitry (20) and decoder circuitry (32). The receiver circuitry (20) receives selective call signals, including reprogramming messages (100). The decoder circuitry (32) decodes the reprogramming messages (100) and produces data in response thereto. The data includes program information (110) and reprogramming data (112). A reprogrammable memory device (70) stores option information for control of various operational features of the selective call receiver. A processor (34) is coupled to the decoder circuitry (32) and the reprogrammable memory device (70) and reprograms the option information in response to the reprogramming data (112) and according to the program information (110).

  • Patent number: 5164737
    Abstract: An antenna (10) is described comprising a generally elongate, magnetically permeable core (12) having a major axis, an insulating substrate (20) being affixed to the core (12) along an axis parallel to the major axis, and having at least a pair of opposed spaced conductive runners (21) positioned along the substrate normal to said major axis. A plurality of charge storage devices (16) are secured between the pair of opposed spaced conductive runners (21). An electrically conductive split sleeve (14) is positioned surrounding the core (12), and has first and second edge portions in electrical connection with the pair of opposed spaced conductive runners (21) opposite said charge storage devices (16). Arrangements for mechanically mounting the antenna (10) are provided which are integral to the antenna (10). The mechanical mounting arrangements are separate from the arrangements provided for electrically connecting the antenna 10 to the receiver.

  • Patent number: 5115182
    Abstract: A battery charging controller which can be integrated within a battery powered device having a rechargeable battery includes a circuit for monitoring the energy consumption of the device from the battery, and for accumulating a measure of the energy consumed since the battery was previously charged. Energy consumption is determined based on the number of device functions being active during predetermined sampling time intervals. When the battery powered device is coupled to an external charging source, the charging of the battery, including the charging rate, is controlled by the energy monitoring circuit within the battery powered device. Rapid charging, slow charging, and discharging of the battery before charging are all readily controlled using an external charging source which requires no circuits for monitoring the battery charging process.

  • Patent number: 4181893
    Abstract: A battery saver circuit for a tone coded personalized radio pager device or the like is described which includes a switchable frequency tone filter to detect a predetermined sequence of tones. One of several alert signals is generated when the correct sequential tone code of the device has been detected.Power is periodically applied to a receiver by a power supply circuit and a control circuit. The first code tone is sampled three times to protect against false identification of this tone. After this first (preamble) tone has been validated, power is supplied for an additional duration of time and the filter is set to detect the next code tone. Once the second code tone has been detected, if the next code tone is not detected within a predetermined time window, the control circuit resets the switchable filter to again search for the second tone of the code. By resetting the filter to detect the second tone, it is possible to condense the broadcast time required for a string of coded messages.
