Abstract: A method (200) for synchronizing wakeup of a second communication device (115) with wakeup of a first communication device (110). The method can include, on the first communication device, receiving a first message (135) from a communications network.

Abstract: The invention concerns a method (200) and system (100) for managing meetings using group calling. The method can include the steps of detecting (212) one or more meeting participants for a meeting, comparing (214) the detected meeting participants with a listing of scheduled meeting participants and generating (216) a dynamic group calling list that at least includes those scheduled meeting participants who have not been detected. As an example, the dynamic group calling list can be generated on a mobile communications device (122) of one of the detected meeting participants. The method can also include the step of simultaneously contacting (218) from the mobile communications device the scheduled meeting participants on the dynamic group calling list who have not been detected.

Abstract: Human hearing perceives loudness based on critical bands corresponding to different frequency ranges. As a sound's frequency spectrum increases beyond a critical band into a previously unexcited critical band, the perception is that the sound has increased in loudness. To take advantage of this principle, a filter is applied to a speech signal so as to expand the formant bandwidths of formants in the speech sample.

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 mobile communication device is provided with an electrical interface in a battery compartment (204) of the mobile communication device. The interface is provided by a flexible circuit member (106) disposed on a radiation shield (100), which is mounted on a circuit board (14) of the mobile communication device. The flexible circuit member and shield are accessible through an opening (206) in the back surface (210) of the battery compartment. Initially the mobile communication device is provided with a label (214) concealing the electrical interface. The label may be removed later so that a battery accessory module (600) may replace a standard battery (502). An accessory circuit (808) in the battery accessory module connects to the mobile communication device through the interface, and provides additional functionality to the mobile communication device.

Abstract: A communication unit (10) can have at least a first receiver (11) and a second receiver (12). The latter typically consumes more power than the former during ordinary operation. Pursuant to one embodiment a communication unit can use the lower-power receiver to detect energy on a monitored channel while the second receiver is retained in a reduced power mode of operation. Upon detecting an absence of channel activity the second receiver can be restored to normal operability to effect such activities as are then presently required.

Abstract: Human hearing perceives loudness based on critical bands corresponding to different frequency ranges. As a sound's frequency spectrum increases beyond a critical band into a pr3eviously unexcited critical band, the perception is that the sound has increased in loudness. To take advantage of this principle, a filter is applied to a speech signal so as to expand the formant bandwidths of formants in the speech sample.

Abstract: In a contactless charging system charging energy is transferred across an inductive coupler to charge a battery (21) of a portable device, such as a two-way radio, cellular phone, paging device, or wireless communicator. The inductive coupler also provides a way for communicating at least one signal, such as to improve the charging process and the transfer of charging energy. Charging efficiency is improved by voltage regulation using feedback through the inductive coupler, or via a wireless RF link, and a controller (11) in-circuit with the primary side (12) of the inductive coupler. The controller (11) may communicate information signals via inductive coupling, or via a wireless RF link, for communicating with other devices such as smart cards and microphones or for control or data transfer.

Abstract: In a time division, multiple access system, a base station (102) transmits an isochronous beacon (404, 422) at the start of each frame (400), conveying control and timing information. Following the isochronous beacon (404), isochronous time slots (414, 416, 418, 420) are dynamically allocated for communication of isochronous data. After communication of the isochronous data, the remainder of the frame (400) before the next isochronous beacon (422) is used for transmission of packets of asynchronous data. This technique gives priority to the isochronous data, which is real time, while also maximizing the bandwidth allocated for asynchronous data. A single transmitter circuit (124, 158) and receiver circuit (122, 156) at each station are used for communication of both isochronous data and asynchronous data.
