Abstract: Un mécanisme de gestion de stockage résident sur un contrôleur de stockage tient des enregistrements de parité relatifs aux unités de stockage qu'il sert. Il comprend un plan mémoire d'état indiquant, pour chaque bloc de données, l'emplacement du bloc de parité correspondant et l'état de chaque bloc de données. Si une unité de stockage particulière fait défaut, le système continue de fonctionner et le mécanisme de gestion de stockage est placé en mode de défaillance. Sous ce mode, le mécanisme vérifie le plan mémoire d'état avant d'accéder aux données de l'unité de stockage défaillante. Si les données n'ont pas encore été reconstituées, le mécanisme reconstitue d'abord les données du bloc de stockage visé en effectuant la lecture et l'accumulation de la sortie d'un circuit « Ou exclusif » des mêmes blocs pour toutes les unités de stockage du groupe de parité, y compris le bloc de parité. Le bloc de données reconstituées est stocké à l'emplacement du bloc de parité, et le plan mémoire est mis à jour afin d'indiquer que le bloc a été reconstitué. Une fois les données reconstituées, il suffit de lire ou d'écrire directement à partir de l'ancien bloc de parité. De la même manière, si le bloc n'a pas encore été reconstitué, le mécanisme de gestion de stockage reconstituera un bloc de stockage de l'unité défaillante avant d'écrire sur tout bloc correspondant d'une unité non défaillante. Dans une autre version, des zones de réserve des unités de stockage non défaillantes sont affectées aux données reconstituées. L'ensemble de ces zones de réserve constitue une unité virtuelle de stockage de réserve.  mesure que les données sont reconstituées, elles sont placées dans l'unité de réserve virtuelle, et la parité est maintenue de la façon habituelle.

Title: Human bipedal locomotion device
Inventor: DICK JOHN G
IPC: A63B23/04
Filed: 1990-07-03
Granted: 1997-04-01
Abstract: A self-actuated spring-action human bipedal device includes a back-mounted frame att-ached to the upper torso of a user, and separate articulated right and left leg frames pivotally attached by U-joints to lower portions of the back frame.  The user's feet are secured to the leg frames so that the bottoms of the leg frames contact the ground, rather than the user's feet, be-hind the point where each foot is attached to its leg frame.  A spring actuator is carried on the back frame, and endless cord-like main springs are engaged with the spring actuator.  Left and right tension lines running from the left and right leg frames to the spring actuator are arranged so that compression of the leg frames, cause by the force of downward movement of the user's feet and torso, acting on the ground, pulls on the tension lines to apply a pulling force to the spring actuator for stretching the main springs.  The tension lines are also each attached to a part of the leg frame which engages on the user's foot so that extension of the user's leg pulls on the tension lines, also stretching the main springs. The energy stored in the stretched main springs is then transferred back to the torso of the user and to the user's feet to cause the user to jump into the air by a distance above the ground approximately proportional to the amount of compression of the leg frame and the amount of stretch transferred to the main springs.  Sepa-rate pick-up springs connected to each leg frame keep the tension lines under positive tension so that tension on each leg frame will not go slack and will apply a pick-up force to the leg frame to raise it and prevent foot dragging to simulate a natural walking gait.

Filed: 1992-12-29
Granted: 1997-06-17
Abstract: An optical sensor for three dimensional shapes includes a laser that produces a lamellar plane beam which illuminates the surface of an object.  The lamellar plane beam produces a curvilinear luminous trace that is scanned by at least one video camera, to produce information that is then converted into digital data representing pixel coordinates.  The sensor includes a lightbox having a common housing that is positioned a short distance above the object to be scanned.  The lightbox housing also includes a laser source that produces a coll1mated rectilinear beam and an optical device for converting the rectilinear beam into the lamellar plane beam. The lightbox housing also includes a device for lengthening the optical path of the lamellar plane beam, comprising two fixed plane mirrors in face to face relationship to produce a plurality of reflections between a bçam entry point and beam exit point of the lightbox.  The small physical distance between the housing and the object is compensated by a virtual optical distance so that there is a correlative increase in the depth of field of the usable region of the lamellar plane beam at the beam exit point from the housing.

Abstract: A Doppler control circuit for a CW or pulse Doppler radar system for monitoring not only the phase shift between echo signals from several targets but also the amplitude difference between the several targets and to further tune the radar to a particular target among one or more targets from which echo signals return. The control circuit can be used in state of the art CW or pulse Doppler type cedar systems. In a further system, a continuously generated radar signal is repeatedly transmitted at different frequencies in time division fashion to define a succession of transmit and receive frames. The receive frames are divided into a plurality of time interval windows with selected windows being used to detect received signals at the different frequencies. The remaining windows can be used for subsystems of the radar system. The rate of phase shift of received signals at a reference frequency is used to determine closing rate (positive ar negative) while the phase shift difference between received signals at two frequencies is used to determine range and target direction. In yet a further system, a special circuit is provided for conditioning selected portions of the Doppler frequency spectrum to attenuate or de-emphasize portions of the echo signal corresponding to selected targets in the radar system environment, such as rain or stationary wayside objects, in order to give such echo signals less weight in determining roadway hazards.
