Abstract: A method for operating a receiver and a device are provided. The device comprises a first and a second antenna, a receiver operationally coupled to the first antenna and a transceiver operationally coupled to the second antenna. The receiver receives information in bursts on a first band of radio frequencies. A controller of the device measures signal strength of the information received with the receiver, compares the measured signal strength to a reference value and enables operation of the transceiver if the measured signal strength is above the reference value, and limits operation of the transceiver during reception of the bursts if the measured signal strength is below the reference value.

Abstract: This invention relates to wireless communication systems, specifically to methods for reducing interference. The invention allows a mobile station to determine if certain transmissions of the mobile station cause interference to reception by a second receiver in the mobile station, and indicate to the network that a change in a transmission parameter of the mobile station is desired. The network can then change a transmission parameter to reduce interference observed by the second receiver.

Abstract: A portable hand-held electronic device including a first section having electronic circuitry with a ground plane and a first antenna adapted to communicate with a mobile telephone system; and a second section movably connected to the first section. The second section includes a second frequency antenna. The second antenna is operably coupled to the electronic circuitry in the first section, and the second antenna is movable with the second section away from the ground plane as the second section is moved relative to the first section.

Abstract: A module for detachable connection to a telephone and a telephone employing such a module. The module includes a device for generating a silent alarm and a system for actuating the silent alarm when connected to the telephone for indicating an incoming call. A pin which provides information about the temperature of the module during charging provides the connection for actuating the silent alarm.

Abstract: A wireless mobile station (10), such as a cellular telephone, executes a method to selectively display one of a plurality of graphical information sequences on a display (20) of the mobile station. The graphical information sequence is displayed during an Idle state of the mobile station, that is, when the mobile station is not involved in receiving a call or during a call. By example, the graphical information sequence can be displayed when the mobile station is in a Keyguard state, and/or in a Charging state, or when the mobile station is first powered on. In a further aspect of this invention the user interface (20, 22) of the mobile station is adapted to enable the user to selectively: enable or disable the display of a graphical information sequence; and/or select a graphical information sequence to be displayed from a plurality of pre-stored graphical information sequences; and/or input a definition of a graphical information sequence from an external source for storage in the mobile station.
