Patent CA-2465815-A1 (CA)
Title: Switch
Inventor: NAKAMURA KUNIHIKO
IPC: B81B3/00
Filed: 2003-06-05
Abstract: A high isolation switch capable of responding at a high rate at a lower DC potential. The switch employs a microstructure group (103) consisting of microstructures (102a, 102b, 102c) and moves each microstructure (102a, 102b, 102c) slightly to obtain a large movement as the group. Consequently, the DC potentials being applied to the control electrodes (106a, 106b, 107a, 107b, 108a, 108b, 109a, 109b) of individual microstructures (102a, 102b, 102c) can be reduced. A high isolation switch (100) capable of responding at a high rate and operating at a lower DC voltage can thereby be realized.

Filed: 2003-02-27
Abstract: La présente invention concerne des techniques pour suivre des trajectoires multiples à espacement mutuel limité et éviter la fusion des doigts sans suivi des positions relatives entre une pluralité de doigts. Dans un aspect de l'invention, des limites de mouvement sont déterminées pour chaque doigt. Des commandes de suivi temporel qui sont susceptibles de modifier la position d'un doigt hors de ses limites de mouvement respectives sont supprimées. Dans un autre aspect de l'invention, des limites de mouvement sont mises à jour de façon dynamique, les limites de mouvement de chaque doigt étant déterminées en fonction des limites de mouvement des doigts adjacents. Différents autres aspect de l'invention sont également présentés. Ces aspects présentent l'avantage d'empêcher la fusion des doigts, ce qui permet l'attribution de multiples doigts à de multiples trajectoires à espacement mutuel limité, et ainsi d'améliorer les performances et la capacité du système, et d'éviter la mauvaise attribution de ressources système.

Filed: 2003-01-09
Abstract: A transmitter (1) transmits from an transmission antenna (7) a synthetic signal produced by combining a part of power of a radio frequency (RF) band modulation signal and a part of power of a local oscillation signal used by frequency conversion; meanwhile a receiver (8) detects it by means of a reception antenna & detection part (9). The reception antenna & dete ction part (9) has basic unit reception circuits (11) each composed of a planar printed antenna (12) such as a patch antenna, an amplifier circuit (13) fabricated i n the form of a small planar circuit by the MMIC technique, and a mixer circui t (14) functioning as a squarer. The powers of the outputs of the basic unit reception circuits are combined and delivered to an IF signal demodulating section. The IF signal demodulating section (10) demodulates the received data. Thus, in a very small space, a reception antenna having a detection function, a high gain, and a wide beam characteristic similar to that of a single antenna is installed.

Title: Viscous damper
Inventor: OSADA KUNIHIRO
IPC: F16F15/167
Filed: 2004-09-10
Abstract: In driving accessories by a crankshaft through a damper, the smooth performance in driving the accessories is ensured by a constitution in which the damper consists of a viscous coupling. The rotational driving force of the crankshaft is transmitted to the viscous damper hub through the meshing of a large diameter gear and a driven gear, the viscous damper forming a unit with the driven gear. The rotational driving force is further transmitted to a viscous damper housing through the hub 31 and the viscous coupling means, i.e., the viscous coupling means comprising a number of plates which are movable relative to each other in a space filled with silicon oil. The rotational driving force, which is transmitted to the housing and is dampened in toque changes by the function of the coupling means, is transmitted to a rotor shaft of an alternator to smoothly rotate the alternator rotor.

IPC: H04N1/405
Filed: 2003-04-28
Abstract: A page-wide array inkjet printer allocates the processing tasks for individu al printheads within the array to separate halftoning processors. Each halftoni ng processor processes the information relating to a strip of the image, with t he boundaries between strips running parallel to the print medium advance direction. In a preferred embodiment, the pixels within each strip are processed using a forward error diffusion algorithm operating along columns of pixels parallel to the strip boundaries. The resulting halftone data is supplied from each halftoning processor to one or more uniquely associated printing component controllers, and these controllers generate print instructions for printing components (e.g. inkjet printheads) connected to t he printing component controllers via a dedicated communications channel.</SDOA B>

Title: Method and system for transaction pipeline decomposition
Inventor: ALLEN RONALD C
IPC: G06Q30/06
Filed: 2003-05-13
Abstract: A method, system, apparatus, and computer program product are presented for decomposing a transaction pipeline by capturing metric data about the completion of transactions within the transaction pipeline, such as an elapsed time that is required to complete a transaction at each stage of the transaction pipeline. A set of agents are among a set of. servers that respond to transaction requests for resources. Two or more servers can be substantially logically grouped into a transaction pipeline in which an upstream server precedes a downstream server if the upstream server initiates a subsequent transaction to the downstream server so as to complete a previous transaction at the upstream server. Each agent is associated with a server in the transaction pipeline. An agent gathers metric data about transactions that are initiated by the agent, which are directed to a downstream server of the server with which each agent is associated.
