Abstract:
A portable wireless transceiver (104) includes a receiver (206) for monitoring transmissions from neighboring transceivers (106A and 106B) to select a transceiver to use for communications. The portable wireless transceiver (104) further has a motion detector (204) for determining whether or not the portable wireless transceiver (104) is moving. If the portable wireless transceiver (104) is determined to not be moving, a processor (202) alters a schedule for monitoring of neighboring transceivers (106A and 106B) so that the monitoring is performed less frequently, thereby reducing power consumption by the portable wireless transceiver (104).
Abstract:
A near field communication loop antenna (308) is mechanically coupled to the cover (300) of a cellular telephone. The antenna (308) is coupled on the inside of the cover (300) between a keypad (302) and the cover (300), whereby the antenna (308) surrounds the keys (314) and is sandwiched between the keypad assembly (302) and the cover (300). A near field communication antenna (406) is coupled to the outside surface of the cover (300) surrounding a display and sandwiched between a lens (400) and the phone cover (300). A near field communication antenna embedded in the phone cover material, whereby the antenna surrounds either the keys or the display, is disclosed as well.

Abstract:
In the present technique for managing power of a transmitter on a mobile station, the transmitter power is checked (124) against a training current threshold that can result in the termination of a training ramp during level training mode of the mobile station. Another transmission current threshold is used for comparison (134) with the transmitter current that effectually reduces the power of the transmitter as needed.
Abstract:
A system and method for reducing the size of a communication device in which a temperature-sensitive, non-heat generating component (302) is placed in close proximity to a heat generating component (304). The temperature of the non-heat generating component (302) is sensed to provide a sensed temperature. The operation of the heat generating component (304) is altered to avoid an over temperature condition of the non-heat generating component (302) based upon the sensed temperature.
Abstract:
A lock-and-key system for selectively enabling and disabling a battery charger is provided. The system lock is provided by a Hall effect switch (140) which, when activated, will allow a battery charger (102) to properly charge a battery (106) loaded thereinto. The key for activating the Hall effect switch is a magnet (142) adapted to apply a magnetic field to the Hall effect switch (140). In embodiments in which the Hall effect switch is disposed in the charger, the magnet is disposed in the battery pack. Conversely, when the Hall effect switch is disposed in the battery pack, the magnet is provided in the battery charger.
