Title: Method and apparatus for partially recompressing digital signals
Inventor: HAMILTON JEFFREY S
IPC: H04N21/2343
Filed: 1995-10-11
Granted: 2001-12-18
Abstract: A method and apparatus are provided for changing the compression level of digital information, such as digital video information. After having been compressed by a first compression scheme that provides quantized transform coefficients, the digital information is partially decompressed to recover the transform coefficients as they were prior to quantizing. The transform coefficients are then requantized at a different compression level. Complexity and expense are reduced by only partially decompressing and requantizing the previously compressed information to modify its compression level without the need to provide components such as a motion compensation processor and frame store that would be required for full decompression of the information prior to recompression.

Abstract: Une rangée de tubes à faisceau électronique (152, 156, 158) est montée sur une plaque conductrice (91, 109, 123) de façon à projeter un faisceau d'électrons en forme de ruban (136, 164, 165) dans l'air, jusque sur un substrat (101) placé sous la plaque. Chacun des tubes dispose d'une fenêtre de rayonnement étroite (51) pratiquée dans une couche mince (73) en matière de nombre atomique faible. Cette couche mince est déposée sur du silicium (71) et protège le tube contre la pression ambiante. Ce type de fenêtre provoque une faible atténuation du rayonnement permettant ainsi l'emploi de basses tensions pour l'extraction. Cette technique réduit l'énergie du rayonnement qui, autrement, se dissiperait en pénétrant au travers de la surface à traiter. Les segments (113, 115) de rayonnement électronique, ainsi générés en forme de ruban, peuvent être disposés en une piste linéaire de rayonnement, ce qui permet, sur toute la largeur de la surface considérée, une feuille ou du tissu (121) par exemple, de procéder au traitement par irradiation par faisceau d'électrons. En outre, les segments de rayonnement peuvent être réorganisés selon toute configuration qui convient. Dans une autre réalisation, les segments de rayonnement générés en forme de ruban peuvent être disposés selon une grille convenant au traitement d'une surface cylindrique telle qu'un câble.

Granted: 2004-03-30
Abstract: A game machine is provided which comprises a display device, a processor connected to the display device and a user input device connected to the processor. The processor is programmed to generate images of playing cards moving from a point on the display device toward a plurality of card hand locations displayed on the display device. To play a card game such as poker on the game machine, a player uses the user input device to select a moving card and direct its movement toward a selected card position in a selected one of the card hand locations. If the player does not select and direct a moving card before a predetermined period of time elapses (e.g., as determined by the time required for a card to travel a predetermined distance) , the processor automatically places the card in one of the card hand locations.

Abstract: A collet chuck (1) having a chuck body (3), a collet (11) disposed in the body (3), a nose ring (23) for radially compressing the collet (11), and a locknut (30) for axially moving the nose ring (23) into compressive engagement with the collet (11) is provided with a bearing assembly (45) disposed between the nose ring (23) and the collet (11) which loads compressive forces in a direction which is advantageously parallel to the axis of rotation (A) of the chuck. Both the locknut (30) and the nose ring (23) include flange portions (27, 43) that confront each other with opposing surfaces (47, 49) that are complementary in shape to the spherical profile of the ball bearings (50) and which traverse a line (L) parallel to the axis of rotation (A) of the chuck. The collet chuck (1) further includes O-rings (61, 65) disposed between the nose ring (23) and the locknut (30) both in front of and behind the ball bearings (50) for sealing the bearing assembly (45) against dust and debris and retaining lubricant. Finally, the portion of the nose ring (23) which wedgingly engages the collet (11) to compress it inwardly is undercut with a groove (72) in order to enhance the compliance between the nose ring (23) and the collet (11), thus providing a more uniform radial compressive force around the collet (11) which in turn results in improved gripping characteristics.

Abstract: A percussion drill bit includes a drill body having a fluid passage formed therein for conducting flushing fluid to a front drilling face of the drill bit.      The fluid passage includes a main portion extending from a rear end of the bit and terminating short of the drilling face, and a plurality of branch lines extending from a front end of the main portion to the drilling face. Front and rear axially spaced seats are disposed in the main portion of the fluid passage. A check valve in the form of a ball is freely movable within the main portion of the fluid passage between contact with the front and rear seats. When the drill bit is oriented upwardly and no flushing fluid is supplied, the ball gravitates rearwardly into sealing contact with the rear seat so that no fluid can flow rearwardly past the rear seat. When flushing fluid is conducted, the flushing fluid pushes the ball forwardly, into non-sealing contact with the front seat and travels past the ball into the branch lines. During downwards drilling, if the density of the ball is less than that of backflowing fluid, the ball will float upwardly upon the back-flowing fluid and into sealing contact with the rear seat.

Title: Periodic process scheduling method

IPC: G06F9/48

Granted: 2008-05-13
Abstract: A scheduling method of a periodic process of a computer system for keeping the execution interval- of each process group constant as far as possible in the case where a plurality of process groups including periodically executed processes are executed in parallel. If a group master process of each process group specifies a wakeup interval period and a required CPU time per period and requests allocation of a CPU time, then a CPU allocation time of a specified process group is secured so as not to collide with a CPU allocation time of another process group, and a scheduling table is created so as to maintain the specified wakeup interval period. In response to arrival of time when one of the process groups should be waked up, a kernel process or a scheduler conducts wakeup by changing execution priority of a process belonging to this process group to highest priority ("raised") in the system, and thereafter maintains the highest priority for CPU allocation time consecutively allocated.
