Title: Method of replicating sata between wireless computing devices
Inventor: EAST SIMON JEREMY
IPC: G06F17/30
Filed: 2002-11-26
Abstract: Resource constrained wireless computing devices (e.g. mobile telephones) are given a replication capability for database records (e.g. to enable backing up contacts, e-mails, photographs etc. onto a remote sewer). This operates without undue processing burden, using low bandwidth unreliable wireless connections. This is achieved by not including a time stamp in each database record, but instead time stamping only a change log record; this approach saves considerable memory space on the wireless device since there is no need to time stamp every database record, as is usually done in the prior art. The change log defines what data is to be replicated; it alone has to be sent to a main server which hosts a master copy of the database and hence has to be kept up to date. Because the change log is compact, far less data has to be sent for data replication purposes - typically only the field which has changed, how it was be changed and when it was changed on the wireless computing device. Prior art systems typically send an entire record, even though that will contain data that has not changed.

Inventor: DILLON MATTHEW
IPC: H04J13/00
Filed: 2003-10-20
Abstract: The invention relates to access management in a radio communication system. A subscriber unit 101 transmits an access message to a base station 101 .

Title: Method for supplying content to a user device
Inventor: JONES EMMA
IPC: H04N7/24
Filed: 2003-10-24
Abstract: A content proxy receives content from a broadcast distribution network, acting as a broadcast overlay network, and provides the content to a base station.

Title: Audio copy protection system
Inventor: ROBINSON DAVID JOHN MICHAEL
IPC: H04H20/00
Filed: 2004-10-13
Abstract: An apparatus for applying an anti-copy protection signal for use with switchable head recorders, such as VHS Video Hi-FI recorders having rotary heads. A high frequency pulsed signal is added to an original audio signal 120. The pulses interfere with the compensator circuitry such that the switching of the record head cannot adequately be masked on recording of a signal. On playback, the switching of the recording heads can subsequently be heard. In Video Hi-Fi recorders, the effect of the high frequency signals also interferes with the compressor-expander circuits to worsen the sound of the head switching.
