Abstract: L'invention porte sur système d'ordinateur comprenant un écran, une unité de disque et un contrôleur central. Le fabricant de l'ordinateur utilise un procédé d'extension de la zone de réserve de l'unité de disque permettant aux fabricants de systèmes d'ordinateurs de modifier la capacité de stockage de la zone de réserve. Ledit procédé consiste à fixer avec le fabricant de l'unité de disque un mot de passe qui valide deux instructions: l'une lit l'adresse maximale ou le nombre maximal de pistes auxquelles l'utilisateur a accès, et la deuxième permet de fixer une nouvelle adresse maximale à laquelle l'utilisateur a accès, le microprogrammé de l'unité de disque étant mis à jour avec la nouvelle adresse maximale. Lorsque les deux instructions ont été utilisées pour l'extension de la zone de réserve, le fabricant de systèmes d'ordinateur peut ajouter des données critiques et des instructions critiques de programme à la zone de réserve étendue ou nouvelle. Le fabricant d'ordinateurs peut décider de stocker une partie d'un programme de détection de virus dans la zone de réserve étendue ou de stocker une partie du système BIOS ce qui permet d'utiliser une ROM plus petite pour le BIOS du système d'ordinateur, ou permettre au constructeur d'ordinateurs de stocker des instructions de lancement dans la zone de réserve en cas de dommage fait au disque.

Abstract: A tracer is provided for tracing a lens mount of an eyeglass frame, a lens or a lens pattern. The tracer comprises an object engager and an actuator. The object engager is adapted to engage the lens mount, the lens or the lens pattern. The actuator is adapted to move the object engager into contact with and then along the lens mount, the lens or the lens pattern in such a way that during movement therealong, the object engager remains against the object being traced even when the shape thereof includes high wrap. Preferably, the tracer has a shift mechanism adapted to shift the object engager from alignment with the lens mount to alignment with a second lens mount of the eyeglass frame. The actuator preferably is further adapted to trace the second lens mount in substantially the same way as the first. The actuator further includes a rotator and a pivot mechanism. The rotator is adapted to rotate the object engager along the object being traced. The pivot mechanism facilitates movement of the object engager toward or away from the axis as the object engager is actuated along the object.

Granted: 2007-12-04
Abstract: A mock translation method and system is provided which converts base-language data and performs a mock translation on it to produce internationalization test data. The mock translation data is created by inserting additional characters, such as a tilde (~) into each of the text strings from the user interface of a software program. The additional characters are used as a placeholder to accommodate the additional space needed for later translating the text into a different language. In addition, field boundary characters, such as brackets, are used to designate the beginning and end of the text with the placeholders. This data is stored in localization files and displayed in a software application in place of the English or foreign-language text. By visually inspecting each screen, the programmer or proofreader is able to easily recognize many internationalization errors, without requiring the ability to read any foreign language. These errors include truncation, alignment, or other formatting errors, and programming errors such as text that is hard- coded, text missing from localization files, localization files missing from the program build, and text composed of more than one translated message.

Inventor: KOZICKI MICHAEL N
IPC: H01L21/822
Filed: 1998-12-04
Granted: 2007-05-22
Abstract: A programmable sub-surface aggregating metallization sructure ("PSAM") includes an ion conductor such as a chalcogenide-glass which includes metal ions and at least two electrodes disposed at opposing surfaces of the ion conductor. Preferably, the ion conductor includes a chalcogenide material with Group IB or Group IIB  metals. One of the two electrodes is preferably configured as a cathode and the other as an anode. When a voltage is applied between the anode and cathode, a metal dendrite grows from the cathode through the ion conductor towards the anode. The growth rate of the dendrite may be stopped by removing the voltage or the dendrite may be retracted back towards the cathode by reversing the voltage polarity at the anode and cathode. When a voltage is applied for a sufficient length of time, a continuous metal dendrite grows through the ion conductor and connects the electrodes, thereby shorting the device. The continuous metal dendrite then can be broken by applying another voltage. The break in the metal dendrite can be reclosed by applying yet another voltage. Changes in the length of the dendrite or the presence of a break in the dendrite affect the resistance, capacitance, and impedance of the PSAM.

Abstract: Selon l'invention, une quantité déterminée de mélange de gaz respiratoire prêt à l'emploi, composé de différents gaz inertes, avec de l'hydrogène et de l'oxygène, est transporté en permanence entre deux contenants de gaz haute pression, dans un système de stockage pendulaire à circuit entièrement fermé. Au départ, le gaz respiratoire nécessaire provenant d'un des contenants de gaz haute pression pénètre dans un circuit, selon le principe du surdosage et sur une base de dosage constant, ledit circuit comprenant un sac d'inspiration, un masque facial, un sac d'expiration, un filtre d'absorption de CO2 simple ou double. A des profondeurs comprises entre 0 et 100 m, le gaz respiratoire utilisé est un mélange d'oxygène, d'azote et d'hélium; à des profondeurs comprises entre 100 et 700 m, une proportion déterminée d'hydrogène peut être ajoutée au gaz respiratoire, à la demande du plongeur, la teneur en oxygène ne dépassant pas 3 % en volume. Lorsque le plongeur remonte à un profondeur inférieure à 100 m, l'hydrogène est éliminé du gaz respiratoire et du circuit par diffusion au moyen d'une membrane de palladium, ou converti en eau par voie catalytique. L'élimination de l'hydrogène est contrôlée au moyen de détecteurs d'hydrogène, et c'est seulement à cet instant que la teneur en oxygène peut être supérieure à 3 % en volume.

Title: Optical packet routing network system based on optical label switching technique
Inventor: SUZUKI SEN-ICHI
IPC: H04L12/56
Filed: 2000-08-24
Granted: 2006-03-14
Abstract: An optical communication equipment comprises shared optical sources to be shared by communication nodes, the wavelengths of optical signals are converted into desired wavelengths according to the addressed information of the corresponding optical label signals by using the shared optical sources, and routed to the addressed communication nodes without being converted into electrical signals by using the wavelength routing function of the cyclic-wavelength arrayed-waveguide grating (AWG). The load of each communication node can be reduced by incorporating the multi-wavelength optical sources , which can be shared among individual communication nodes, into the router.      Further, each communication node is provided with an optical gate or the like for returning the optical signal to the communication node from which the optical signal ha been transmitted through the router in order to adjust the transmission time lag between the optical signal and the corresponding optical label signal by the controllers. In this way, the setting of the transmission time lag by each communication node can be made easier, thereby largely reducing the work load.

Abstract: An overload relay includes a base (22) with electrical contacts (162, 164) thereon. A lever (116) including a contact actuator (140) is in proximity to the contacts (162, 164) and a pivot (122) mounts the lever (116) on the base (22) for pivotal movement between first and second positions. A releasable latch (106) normally holds the lever (116) in a particular one of the positions and a spring (144) is interposed between the base (22) and the lever (116) at a location spaced from the pivot (122) to bias the lever (116) toward the other of the positions by applying a bias thereto in a generally predetermined direction. The direction and location are such that when the lever (116) is in a latched position, the bias will provide a relatively small force tending to move the lever (116) toward the unlatched position and further is such that as the lever (116) moves towards the first position, the bias produces an increasing force tending to move the lever (116) towards the unlatched position.
