Title: Method for detecting transverse vibrations in an ultrasonic hand piece
Inventor: WIENER EITAN
IPC: A61B17/32
Filed: 2001-10-17
Granted: 2010-10-12
Abstract: A method for detecting transverse mode vibrations in an ultrasonic hand piece/blade is achieved by monitoring the power delivered to the hand piece/blade to determine whether it increases as expected when power levels applied to the hand piece/blade are changed. While the blade is being held in midair, the power delivered to the hand piece/blade and for the impedance of the hand piece/blade is measured at a first power level. Using the value obtained at the first power level, the expected power at a second power level is calculated and used to set a pass/fail threshold level for an actual measured power. Alternatively, the threshold is set for the impedance is set. Next, the actual power delivered to the hand piece/blade and/or the impedance of the hand piece/blade is measured at a level 5 power setting. A determination is made whether the hand piece/blade exhibits transverse mode behavior based on whether the actual measured power exceeds the established pass/fail threshold level. If this is the case, operation of the generator is inhibited, a "Transverse Mode Vibrations Present in Hand Piece/Blade" error code is stored in the generator, and a "Bad Hand Piece" message is displayed on a liquid crystal display on the generator. In addition, a method for detecting transverse mode vibration in an ultrasonic hand piece/blade is achieved by monitoring power delivered to the hand piece/blade to determine if the an extraordinary power increase occurs as the drive frequency is shifted downward and/or upward from a primary intended resonance operating frequency.

Abstract: La présente invention concerne la commande de signalisation pour des systèmes employant l'adaptation des liaisons et la redondance incrémentielle. Un message d'adaptation de liaison/redondance incrémentielle peut être envoyé par une entité réceptrice à une entité émettrice pour informer cette dernière de l'état de redondance incrémentielle ou de la préférence de l'entité réceptrice. Un autre message, qui indique si une nouvelle segmentation doit être effectuée pour des blocs retransmis peut également être envoyé d'une entité réceptrice à une entité émettrice. Ces deux messages peuvent être utilisés par l'entité émettrice pour déterminer un plan de modulation/codage destiné aux transmissions suivantes à la fois de blocs de données de départ et de blocs de données retransmis. Les messages peuvent être utilisés ensemble ou de manière indépendante dans une liaison quelle soit montante ou descendante entre une station de base et une station mobile dans un système de radiocommunications.

Title: Method and apparatus for efficient reactive monitoring
Inventor: DILMAN MARK
IPC: H04L29/06
Filed: 2002-02-18
Granted: 2006-07-04
Abstract: A technique for managing network elements significantly reduces the amount of monitoring related traffic by using a combination of aperiodic polling and asynchronous event reporting. A global resource (e.g., a network of interconnected nodes or resources) is partitioned into a plurality of separate nodes, giving a fixed resource budget to each of the nodes. When any of the nodes exceeds its budget, based upon local monitoring at that node, the node triggers a report, typically sending a message to a central manager. In response, the central manager then and only then issues a global poll of all (or substantially all) of the nodes in the network. A rate based technique can also be used to monitor resource usage at the nodes, and send a message to a central monitoring location only when the rate at which the value of a local variable changes is too high.
