Title: Low delay atm switching system using idle cells stamped with reference time
Inventor: FAN RUIXUE
IPC: H04L47/6275
Filed: 1993-01-26
Granted: 1998-12-22
Abstract: In a multi-stage switching system, a time stamp is attached to each cell at an entry point of the system indicating the time of arrival of the cell, and the cell is transferred to a network comprising multiple switching stages each being composed of basic switching modules. The switching modules of all stages are interconnected to form the network. Each switching module comprises a self-routing switch and buffers connected thereto. The time stamp of cells arriving at a given one of the switching modules, where the cells are likely to arrive out of sequence, is constantly monitored and a minimum value of the time stamps is detected. When an empty buffer exists in the given switching module, an idle cell containing the time stamp of the minimum value is generated at the output of the empty buffer.

Title: Systeme de reglage de siege de vehicule
Inventor: HUGHES DANIEL
IPC: B60N2/12

Granted: 1998-04-14
Abstract: Dispositif de fixation de siège de véhicule, pour sièges comprenant un coussin de siège et un dossier qui s'incline sur le coussin de siège lorsqu'il passe d'une première position relativement verticale à une seconde position relativement repliée. Le dispositif de fixation est constitué d'une coulisse, solidement fixée sur le véhicule, dans laquelle se déplace un coulisseau auquel est solidement fixé le siège. Un câble relie le dossier et le bras d'un dispositif de commande. Lorsque le siège est déplacé vers l'avant pour donner accès aux sièges arrière du véhicule, le câble soulève le bras et le fait passer d'une position neutre à une position relevée, ce qui entraîne simultanément le déplacement d'un galet de came d'une position relevée à une position abaissée. Le galet de came retient le bras en position relevée contre la force exercée par un ressort. Lorsque le siège est ramené en position normale, le galet de came entre en contact avec une came située sur la coulisse ou sur le coulisseau dans une position préétablie, ce qui provoque le déplacement du galet de came, d'une position abaissée à une position relevée. Le bras est alors débloqué et reprend sa position neutre tandis, que le mécanisme de verrouillage de la coulisse peut se verrouiller de nouveau et bloquer le siège dans la position préétablie.

Abstract: The locking arrangement comprises a movable control member at the wing and a stationary counter-member at the frame. The control member is arranged at a connecting rod and is displaceable longitudinally along with the latter by means of a handle. In this way, the locking arrangement is displaced between a closing position and a releasing position. In order to achieve a trouble-free arrangement with a reliable closing position, it is proposed to provide at least one lever with a hook opening in the counter-member which cooperates with the control member as a hook lever. This hook lever is swivelable transversely to the displacement direction of the control member. In the closing position, the hook lever is swiveled toward the control member until a hook opening receives the control member and its outer hook leg engages in front of the control member. In the releasing position, the hook lever is swiveled away from the control member and its outer hook leg is situated outside of the displacement direction of the control member.

Abstract: An electronic price label (EPL) price verification system which ensures that a price for an item obtained from a price look-up (PLU) file by a bar code scanner is equal to another price displayed by an electronic price label (EPL) for the item.  The EPL price verification system includes a computer system coupled to the EPL, which includes a terminal and a storage medium coupled to the terminal.  The storage medium contains an EPL data file, which contains EPL identification information and an EPL price verifier.

Title: Lamp starting circuit
Inventor: NUCKOLLS JOE A
IPC: H05B41/04
Filed: 1996-08-28
Granted: 2005-11-15
Abstract: A hot restart circuit for a high intensity discharge lamp includes a storage capacitor and SCR connected across a tapped portion of a ballast with a breakdown device to start the SCR. A charging circuit for the storage capacitor includes a diode, a pumping capacitor and an RF choke in series from the ballast tap to the AC line, and a further diode interconnecting the capacitors. The pumping capacitor increases the charge on the storage capacitor in a stepwise fashion until breakdown voltage is reached, whereupon starting pulses are applied to the lamp. A positive temperature coefficient (PTC) resistor stops the flow of charging current to the capacitors after a predetermined interval, thereby terminating the reignition pulses and protecting the starting circuit from damage in case the lamp fails to reignite. In an alternative embodiment, a MOSFET gated by an RC timing circuit removes charge from the storage capacitor in order to terminate the reignition pulses after a predetermined interval.
