Abstract: Permanent reception stations 1 comprising a heavy pedestal 2 provided with housings for seismic pickups, geophones 6 & hydrophone 7, intended to receive acoustic or seismic signals from the underlying formation are arranged at the bottom of the water mass. When collection sessions for the signals received by the pickups are scheduled, data acquisition stations 11 are connected by a cable to the various permanent reception stations 1 and laid at the bottom of the water mass. The signals picked up are then recorded 14 for the time required to carry out at least one session of acquisition and recording of the acoustic or seismic signals received by the passive stations in response to the emission of seismic waves by one or more seismic sources. The mobile acquisition stations 11 are then recovered at the surface and the records acquired by each one are transferred to a central collection laboratory.

Title: Method and apparatus for testing timing constraints
Inventor: BRISTOW PAUL CRISPIN
IPC: G06F11/34
Filed: 2003-09-23
Abstract: A method (300) for generating an automatic test script for a system specification having one or more timing constraints comprises the steps of automatically mapping one or more automatic test scripts employing one or more timers to one or more timing constraints; and generating an automatic test script for a system specification there from. In this manner, an algorithm is able to augment, say, a tree representation of a test script using timers to test whether timing constraints on a notation, such as MSCs, are met. Thus, timing constraints are used to provide an indication that an event should (or should not) happen within a given window of time.

Title: Thin film magnetic head with thermal dissipation
Inventor: SATO KIYOSHI
IPC: G11B5/40
Filed: 2004-02-20
Abstract: By forming a rearmost second coil piece 56A so as to have a larger width in the track width direction X and a larger area than those of the corresponding coil pieces lying forward thereof, heat generated in a thin film magnetic head can be effectively released to the rearmost coil piece.

Title: Watermarking a compression encoded video stream
Inventor: WILLIAMS MICHAEL JOHN
IPC: G06T1/00
Filed: 2005-05-05
Abstract: An encoding data processing apparatus is operable to introduce a visible watermark into a compression encoded video image represented by a compression encoded bit stream having a predetermined format. The format of the compression encoded bit stream provides image frames, which are represented by macroblocks, each macroblock representing a block of pixels from the image frame. The macroblocks are formed into groups of macroblocks which are contained in fixed portions of the compression encoded bit stream, the fixed data portions being able to accommodate a predetermined fixed amount of data. The encoding data processing apparatus being operable to parse the compression encoded bit stream to identify spare data capacity in each frame provided from each of the fixed data portions as a result of the fixed data portion not being completely filled with the macroblocks. The encoding data processing apparatus is operable to determine whether an additional amount of data required to represent the visible watermark can be accommodated in each image frame. If the additional data can be accommodated, the encoding data processing apparatus is operable to change selected macroblocks in the image frame to represent the visible watermark, to generate a bit pattern representing the macroblocks in the original image frame which have changed, and to insert the additional data into the fixed data portions of the image frame. A visibly watermarked bit stream can therefore be produced in which the watermark changes on a frame by frame basis, if the frames can accommodate the data required to represent the watermark. In one example the visible watermark represents a time code.

Patent GB-2411128-A (GB)
Title: Putter with distance measuring function
Inventor: KOIWAI HIDEAKI
IPC: A63B57/00
Filed: 2004-03-16
Abstract: A logical putter not based on a conventional experiential rule but based on measurement data. A distance-to-cup measuring rule is such that grip end face of the putter is aligned with the height of eyes and then the putter is suspended right above a ball while stretching the arms. When a cup is looked under that state, distance from a position where the line of sight intersects the grip part to the cup is determined. Since the measurement of distance depends upon the individual height, height of a player is preset by an electronic circuit contained in the grip part and a microcomputer calculates a distance count up to the cup by judging and inputting the intersecting position of the line of sight through sequential lighting of LEDs arranged in series. Furthermore, a putting operation is regarded as pendulum operation integrating the arm and the putter and then a recommended take-club-back amount is determined theoretically for the distance count of a rolling ball and delivered to a liquid crystal display along with the distance count. Since the measured distance count and the recommended take-club-back amount depend significantly on the inclination angle of a green surface, an inclination angle sensor is built in the vicinity of the center of the putter head, and distance count and take-back amount determined previously are corrected automatically based on an angle measured by laying the putter.
