    摘要: Synchronized UWB piconets for SOP (Simultaneously Operating Piconet) performance. A common backbone (either wired or wireless) is employed that provides a common CLK (clock signal) to all of the various PNCs (piconet coordinators) of various piconets that may operate within a sufficiently close region such that interference could undesirably occur. By providing a very reliable CLK signal from a common backbone to all of the PNCs of the various piconets operating within a substantially close proximity to one another, very precise synchronization may be ensured for all of the communications performed therein. The various piconets may then even operate using TDMA (Time Division Multiple Access)—whose performance would be substantially compromised without effective synchronization. In addition, combined TFC (time frequency code) and TDMA may also be employed to support the communications therein thereby providing even another degree of orthogonality that provided by TDMA alone.

    摘要: A method and apparatus for quickly copying a first frame region into a second frame region. A video memory array comprising a plurality of video random access memory devices is divided into at least two frame regions. A background image is rendered by a central processing unit into a background frame region within the video memory array. The central processing unit then requests the background image in the background frame region to be copied into a new frame region in the video memory array. A dedicated circuit copies the entire background image in the background frame region into the new frame region. The dedicated circuit operates by using a serial data register within each video random access memory device during the vertical retrace period of a video timing signal. The dedicated circuit performs the background frame copy without requiring any processing resources from the central processing unit.

    摘要: A control device method and apparatus has application for use in multi-media systems. The multi-media system contains a host computer having a video display, a control device and at least one target device. The target device is any remotely controlled equipment that the user wishes to integrate into the multi-media system. The host computer contains a host system configuration which provides the user the ability to select an operating mode for the control device. The control device operates as an interactive user interface to control a cursor on the host computer video display when the control device is placed in the cursor control mode. The user selects a remote control mode to remotely control the target devices using the control device. The host system configuration also includes learn and computer networking modes. In the learn mode, control data information is entered into the host system configuration for new target devices. In the computer networking mode, the control device operates as a network interface allowing other similarly equipped computers to communicate with the host computer.

    摘要: A paging system which sends and receives encrypted messages. The message may be encrypted either by the sender of the message or by the paging system. Multiple keys may be used for encrypting and decrypting. Public key systems may also be used and integrated into this paging system. The paging system can send out time update messages containing the current time and date. The pagers use the time update messages to automatically update the time in an internal clock. Time stamps can be inserted into the encrypted messages to prevent unauthorized users from replaying old messages.
