Cellular telephone system integrated with paging network

Abstract: A telephone system with which a connection between two subscribers can be established, at least one of them being a mobile subscriber. The system includes a paging network composed of one or several extensive paging ranges, each of them having a paging transmitter (H1, H2) of its own, a small cellular network with an exchange and a plurality of base stations (T), and mobile telephones with which a pager has been integrated. When calling a mobile telephone, the transmitter of the paging range in which the telephone is known or assumed to be transmits a paging message to the telephone, whereby, when the telephone is in the neighborhood of the base station, the exchange of the cellular network establishes immediately a connection between the subscribers. No paging calls are lost because they are stored in the exchange of the cellular network, and on an appropriate occasion the pager of the telephone and the exchange compare the paging messages stored in the memories. The call can be transmitted from one base station to another during the call (handover).

Antenna switching circuits for radio telephones

Abstract: Disclosed are various embodiments of circuitry for coupling first and second transceivers of a dual band radio telephone to integral and external antennas. The circuitry uses impedance matching lengths of transmission lines and switches arranged to provide a minimum insertion loss. Also disclosed is an embodiment for use with a single band radio telephone, such as a digital TDMA radio telephone that either transmits or receives at any given time. Also disclosed is an antenna switching arrangement for a dual band phone that eliminates a requirement for duplexers.

Performance optimization in solid-state media

Abstract: A host device is coupled to a peripheral device such as a multi media card or the like, where the peripheral device includes a solid state data storage segment. The peripheral device has means for initiating a defragmentation function, such as registers for comparing a current performance measure against a threshold performance metric, or block validity parameters received form the host device for the data storage segment of the peripheral device. Once met, the means for initiating cause a defragmentation function to execute on the data storage segment. A logical layer of the data storage segment is accessed by the host device and a physical layer of the data storage segment is accessed by the peripheral device. The defragmentation program may be resident on either the host or peripheral device. Defragmentation may be enabled to execute automatically once initiated, such as by a continuous or periodic background scan of current performance of the data storage segment.

Synchronized service provision in a communications network

Abstract: The invention relates to the synchronized playback of video and/or audio recordings in terminals of a communications network. A server stores recordings including timing markers, each of which indicates an internal position within the recording. The system comprises groups of user terminals, at least one channel being assigned to each group. A recording is transmitted to the terminals belonging to the same group and stored there. In response to a start command, the playback of the recording is started at each terminal. Status information indicating at least the playback position of the recording is maintained, and the playback is controlled by transmitting new status information to the terminals of the group. The playback status is changed at each terminal according to said new status information.

User interface, device and method for a physically flexible device

Abstract: A user interface, a device and a method for a physically flexible device including a flexible display (400) configured to display graphical objects (410) and a controller configured to detect a first bend and determine a resulting first foldline (411 ), determine a graphical object being intersected by the first foldline (410a, 410b) and execute a function associated with the graphical object. In another embodiment, a controller is configured to detect a bend resulting in a shape and execute a function associated with the shape. In another embodiment, a controller is configured to detect a bend of a corner and execute a function associated with the corner.
