Title: Packet switching using a hardware router and FIFO proceedure
Inventor: YEOM YOON-JONG
IPC: H04L12/70
Filed: 1996-06-25
Abstract: A packet data transmitting apparatus and a method therefor are disclosed in which a hardware router transmits and receives packet data without utilizing a central processing unit. By utilizing a hardware router, the destination address is detected from the packet data. Then the packet data are transmitted in accordance with the detected destination address. That is, the hardware router designates respective nodes in a sequential manner, and confirms the existence or absence of the packet data to be transmitted. Then the destination address is extracted from the packet data to be transmitted so as to discriminate the transmitting nodes. Thus a transmission path is provided between the transmitting nodes and the receiving nodes. Therefore, without using the central processing unit, the packet data can be communicated with hardware, with the result that the central processing unit is not over-loaded. Consequently, the performance of the central processing unit is improved, and the processing speed of the system is improved. Therefore, the present invention can be applied to a system requiring a multitasking, and to a system requiring a high speed accurate routing.

Title: Security system detects user proximity to computer apparatus
Inventor: EVANS IAN DAVID
IPC: G06F21/84
Filed: 1998-12-31
Abstract: Unit 6 plugged permanently into the video-output (8, Fig. 2) of data-processing unit 2 maintains video-signal supply to monitor 3 only while a radio signal, sent by a badge or card 14 worn by an operator, continues to be received by loop-antenna 12 (e.g. incorporated in a mouse mat 13). The signal, possibly encoded, is transmitted from card 14 by a transponder (15, Fig. 2) in response to reception of a radio-frequency, possibly encoded, signal transmitted from antenna 12. When the card-signal is no longer detected, i.e. the operator moves out of range of the antenna 12, a switching circuit (9, Fig. 2) in the unit 6 is deactivated to block the video-signal supply to monitor 2. The video-signal supply is restored when the card-signal is detected again. The unit can also be arranged to interrupt the supply of signals to and from the processing unit 2, e.g. to/from the keyboard, mouse, printer (Fig. 3). The screen 4 can be left blank during interruption, or driven by an auxiliary video-signal source (36, Fig. 4) to provide a message/pattern display.

Title: Retrievable bridge plug and packer forming an isolated zone
Inventor: HENLEY DAVID A
IPC: E21B33/124
Filed: 1999-06-10
Abstract: A bridge plug (BP, see fig 1F) and a packer (P) can be run into a well together and set in a single trip without the need for rotation so that the apparatus can be used with coiled tubing. The bridge plug is set initially using hydraulic pressure applied to engage slips (116, see fig 1E) from the surface whilst the packer is locked against setting. Longitudinal movement of the drill string then compresses sealing elements (122, see fig 1F) on the bridge plug. The packer is then disengaged from the bridge plug closing a circulation ball valve (84, see fig 1D) allowing flow through the bridge plug and releasing the lock preventing setting of the packer. The packer is subsequently set with slips (14) and sealing elements (54) once in the desired location by either fluid flow or longitudinal movement. Once treatment procedures have been conducted on the isolated zone the bridge plug and packer can be unset and moved to a further location requiring treatment without removal from the well. The bridge plug and packer can be set different distances apart and so zones of various lengths treated.
