Patent GB-2427701-A (GB)
Title: Calibrating delay lines
Inventor: OWENS RONNIE E
IPC: G01R31/28
Filed: 2006-06-19
Abstract: A delay line (DL) circuit 1 used to generate test pattern waveforms has a pulse generating circuit that is used during calibration to generate a pulse signal upon receiving a signal edge. A delay line 20 of the DL circuit receives the pulse signal and delays the pulse signal by a selected time delay. A feedback loop 17 of the DL circuit feeds the delayed pulse signal output from the delay line back to the input of the pulse generating circuit 10. Receipt of an edge of the fed back pulse signal at the input of the pulse generating circuit causes the pulse generating circuit 10 to generate another pulse signal. The delayed pulse signal output from the delay line can be input to a counter 50 that generates a counter value that is based on the period of oscillation of the delayed pulse signal. Delay line circuits are utilised in automated test pattern generators (ATPG) used for testing integrated circuits (IC).

Title: Automatic steering of marine seismic towing vessels
Inventor: HOLO ANDREAS THIBLIN
IPC: G05D1/02
Filed: 2006-08-09
Abstract: Systems and methods for automatic steering of marine seismic towing vessels are described. One system comprises a vessel V towing a seismic source S1, S2, and optionally one or more seismic streamers ST, a vessel steering sub-system including a vessel steering algorithm for calculating an optimum vessel steering path. A controller produces a difference between a measured position of a tracking point TP with a pre-plot position of the tracking point, and calculates a set point based on the difference to the steering algorithm. The tracking point TP may be anywhere in the spread, eg between the streamer front end center SFC and the center of source CS. The steering algorithm may take into account current and wind information. The vessel may tow a marine seismic seabed receiver cable. The controller may be selected from PI, PD, PID or MP controllers. The automatic vessel steering enables improved repeatability, eg in 4-D seismic surveying, without relying on operator skill and alertness.

Title: Fast turn on of a computer operated device by running the BIOS to boot the operating system when power is supplied before the device is turned on.
Inventor: HILL GREGORY S
IPC: G06F9/445
Filed: 2006-10-26
Abstract: A computer controlled system that appears to instantly turn on is disclosed. The system boots the operating system completely when power is applied to the instrument system, eg plugged into the mains, before the system is turned on by the user, ie in an off mode. The OS brings the instrument system to the point where all internal checks have been accomplished but does not turn on any externally detectable functions, eg the display. Once the OS has booted, the hard drive is stopped, the clock rate is reduced, and power is removed from any PC cards. The system enters a sleep mode. When a user turns on the system, the clock rate picks up, and all other functions come alive. When the user turns the instrument system off, the system reboots and then returns to the sleep mode. The system may be an instrumentation system that is turned on by the user when a measurement is required, rebooting and entering the low power, sleep mode when connected to a power source but no measurements are required ie the system appears to be off.

Title: Parallel context determination in context adaptive binary arithmetic (CABAC) decoding
Inventor: PEARSON ERIC C
IPC: H04N19/00
Filed: 2007-01-09
Abstract: A first circuit is configured to present a video signal and macroblock data in response to decoding one or more bins on a binary signal. A second circuit is configured to, in parallel, (i) generate the binary signal in response to a bitstream signal and an initial context information and (ii) calculate subsequent context information. This means that the CABAC decoder determines the context information to decode a bin before the bin is decoded, thereby speeding up processing. The decoder may find application in high definition (HD) video decoding.
