Title: Rerouting and change-back systems for asynchronous transfer mode network
Inventor: HYODO RYUJI
IPC: H04L45/28
Filed: 1991-06-17
Granted: 1998-07-28
Abstract: A change-back system is designed for an asynchronous transfer mode network in which a rerouting path is set to replace an original path when a fault is generated in the original path within the network, which network includes a plurality of communication nodes which are coupled via lines and communicate information in the form of cells, and the original path and the rerouting path couple first and second communication nodes within the network.  The change-back system makes a change-back process to change the path used from the rerouting path to the original path when the fault is restored.  The change-back system includes a first circuit for detecting a restoration of a fault in the original path, a second circuit for transmitting a cell from the first communication node to the second communication node via each of the rerouting path and the original path when the restoration of the fault is detected, prior to making the change-back process, and for measuring a first time it takes for the cell to travel through the rerouting path and a second time it takes for the cell to travel through the original path, and a third circuit for calculating a guard time which is a difference between the first and second times and for delaying transmission of a cell from the second circuit to the original path after the restoration of the fault, so that the cell after the restoration of the fault is transmitted to the original path at least after a time which corresponds to the difference from a time when a cell is last transmitted to the rerouting path immediately before the fault is restored.

Title: Bi-directional down drive assembly for a document track
Inventor: HANNA PETER D
IPC: B65H9/10
Filed: 1991-09-27
Granted: 1995-12-26
Abstract: An apparatus for moving a document towards the bottom of a document track as the document is moved in first and second directions within the track. The apparatus includes a feed unit positioned on one side of the document track and a cooperating unit positioned on the opposed side of the track.  The cooperating unit has a rod which is pivotally supported in a support.  A high friction roller is secured to the top end of the rod and a low friction roller is rotatably supported on the lower end of the rod.  The feed unit has an idler roller positioned opposite to the high friction roller and also has a drive roller positioned opposite to the low friction roller in the cooperating unit.  As the document is moved in a first direction in the document track, the high friction roller causes the rod to pivot slightly, thereby causing the low friction roller on the bottom of the rod to cant slightly, producing a downward component of force on the document as it is moved in the first direction.  When the document is moved in the opposite direction, the low friction roller is canted slightly in the opposite direction to produce a downward component of force on the document as it is moved in the second direction.

Abstract: A scroll type fluid displacement apparatus, in particular, a scroll type compressor, is disclosed.  The apparatus includes a pair of scroll members at an angular and radial offset for forming fluid pockets, each scroll member having a spiral element.  A bypass hole is provided on a wall of at least one of the spiral elements of the scroll members for communicating between the fluid pockets and a suction chamber.  A valve mechanism, which operates in a radial direction, controls the opening and closing of the bypass hole.  The valve mechanism is responsive to the rotational motion of the scroll members and/or the pressure in at least one of the fluid pockets.  When the apparatus is driven at excessive speed, the valve mechanism operates in response to centrifugal force to open the bypass hole.  The compressed fluid in the fluid pockets then is released into the suction chamber through the opened bypass hole, and the compression capacity is reduced to a proper value.          Additionally, when the pressure in the fluid pockets becomes excessive, the valve mechanism operates to open the bypass hole to thereby decrease the pressure a proper value.

Title: Method for compensating for receiver gain compression
Inventor: AULERT MICHAEL C
IPC: H04M1/725
Filed: 1994-08-05
Granted: 1998-04-21
Abstract: A method provides a handshake (42) between a handset and a bass of a wireless communication system if a "no carrier signal" condition is detected based upon a receiver signal strength indicator (RSSI) signal. The step of providing a handshake (42) further includes a step of incrementing the channel (44) to ensure that the handset and the base are communicating on a clean channel. Because a false RSSI signal may be generated as a result of receiver gain compression, the connection between the handset and the base will not be terminated if a return handshake (58) is received from the handset. Therefor, method compensates for receiver gain compression.

Abstract: L'invention concerne un dispositif (10) pour plier des lentilles intraoculaires, doté d'un cadre (12) ouvert sensiblement plan et ayant la forme d'un "A" arrondi ayant une tête ouverte (14) avec un bord en haut du "A". La base du "A" forme une paire de pieds ou poignées (16) opposées qui se rejoignent pour former une charnière (23) au niveau de la fourche où les poignées viennent se fixer à la tête. La charnière permet de serrer les deux poignées l'une vers l'autre tout en leur permettant de se séparer élastiquement lorsque la compression est relâchée. Le serrage des poignées provoque la compression de la partie supérieure (20) du bord (18) de la tête et son mouvement vers la charnière. La tête ouverte comporte une pluralité de saillies se terminant par des mâchoires ouvertes relâchées (24, 26, 28) dans lesquelles est placée la lentille intraoculaire. L'emplacement des saillies est tel que, lorsque les poignées sont serrées ensemble et que le rebord se déplace vers la charnière, deux des mâchoires se déplacent l'une vers l'autre, en faisant en sorte que la lentille intraoculaire se plie au milieu.
