  • Patent number: 5408693
    Abstract: A radio communication device (10) comprises a radio transceiver (12), having a received signal strength indicator (RSSI) (16), an audio section (22), and a controller (16) for deactivating the audio section whenever the RSSI indicates the the received signal strength is below a predetermined threshold. The controller also operates as a counter (26) for indicating the length of time that the received signal strength has been below the predetermined threshold.

  • Patent number: 5265271
    Abstract: An electronic device (100) operating on a battery voltage (126) is disclosed having a regulator (108) for producing a first reference voltage (106) and a second reference voltage (110). The electronic device (100) includes an A/D converter (114) for comparing the battery voltage (126) to the first reference voltage (106) to produce a first sample. The A/D converter (114) also compares the second reference voltage (110) to the first reference voltage (106) to produce a second sample. The two samples are then subtracted at a micro-computer (112) to produce a difference sample. The micro-computer (112) compares the difference sample to a first value and detects low battery conditions when the difference sample is below the first value.

  • Patent number: 5259021
    Abstract: A public telephone network to portable telephone interconnection device (20) is provided. At least one transceiver (30a-n) interconnects a plurality of portable telephones (12) to the public telephone network (16). A channel monitor (38) monitors the transceivers (30a-n and 82) to provide information. At least one information transceiver (82) interconnects the plurality of portable telephones (12) to and is responsive to the monitor (38) for transmitting (104) the information to the plurality of portable telephones (12).

  • Patent number: 5138650
    Abstract: A method of handling a charge authorization in a cordless phone (12) is provided wherein a memory (53) in the cordless phone (12) is credited (634) by a value representing a purchased amount prior to a usage of the cordless phone (12). The usage of the cordless phone is allowed (420) depending on that value which is debited (522) during the usage of the cordless phone.
