Title: Drilling string torsional energy control assembly and method
Inventor: PALMER LARRY G
IPC: E21B17/00
Filed: 2004-05-19
Granted: 2009-02-03
Abstract: The present invention provides a torsional energy control assembly and method for eliminating slip-stick and/or drill bit oscillations comprising axial and/or rotational oscillations. In one preferred embodiment, the assembly permits slippage between an upper portion of the drilling string and a lower portion of a drill string. The rotational control assembly may be installed at any desired position in the drill string. The rotational control assembly could also be utilized as a component of other drilling mechanisms such as a downhole drilling motor. The rotational control permits slippage while drilling for a selected time or selected rotational distance or other criteria to thereby release torsional energy in the drilling string which otherwise may produce damaging slip-stick torsional oscillations such as slip-stick. The rotational control assembly may, in one embodiment, comprise an on-off clutch whereby torque is either substantially completely transmitted or substantially not transmitted through the assembly for brief periods.

Filed: 2006-03-23
Granted: 2011-07-05
Abstract: Mechanical compression and vacuum release mechanisms which are of simple construction and which significantly reduce the effort required to start an internal combustion engine. In several embodiments, the compression and vacuum release mechanisms include a centrifugally responsive flyweight pivotally mounted to the camshaft, the flyweight coupled to a pair of compression and vacuum release pins which include respective compression and vacuum release cams that are in lifting engagement with the valve actuation structure of one of the intake or exhaust valves of the engine during engine starting to relieve compression and vacuum within the combustion chamber and thereby facilitate easier engine starting. After the engine is started and reaches running speed, the flyweight pivots responsive to centrifugal force and in turn pivots the compression and vacuum release cams out of engagement with the valve actuation structure of the intake or exhaust valve to allow the engine to operate normally.

Abstract: Structure à ressort comportant des caractéristiques de prévention des contacts et de renforcement de la rigidité d'un matelas de lit, dans laquelle la structure d'une extrémité de connexion servant à relier un ressort central et un ressort en fil d'exposition l'un à l'autre est améliorée de manière à ce que l'extrémité de connexion ne soit pas en contact étroit avec un enroulement supérieur et/ou un enroulement inférieur du ressort central. Lorsqu'une charge est exercée sur un ressort en fil d'exposition, le déplacement est freiné, car le ressort en fil d'exposition est incliné d'un côté et la rigidité du ressort est renforcée afin de permettre au ressort en fil d'exposition de se mouvoir uniquement à la verticale vers le haut et le bas, prévenant ainsi aisément le déplacement latéral et la déformation du ressort, tout en évitant l'émission de bruits causés par un contact de frottement afin de prolonger la durée de vie du ressort.

Abstract: A system and method for classifying channels in a frequency hopping wireless communication system is provided. A data collection engine operates to obtain channel metrics (30) indicating the level of interference for each channel used by the wireless communication system. A data analysis engine (32) operates to provide a channel map for adaptive frequency hopping (AFH) (26) and/or a channel map for channel avoidance (24). More specifically, the data analysis engine first operates to filter the channel metrics to remove channel metrics indicative of frequency hopping interference. Next, the channels are divided into a number of channel blocks each including at least two adjacent channels. For each channel block, the channel metrics of the channels within the channel block arc combined to provide a metric sum. The data analysis engine then operates to classify each channel as usable or unusable based on the metric sums for each of the channel blocks.

Abstract: Data packets are transmitted from a first access network to a first interface of a multiple interface device (MID), and identical data packets are transmitted concurrently from a second access network to a second interface of the MID. Some of the data packets that are transmitted to the MID from the first access network are not received by the first interface. The MID inspects identifiers of data packets from the first and second interfaces in order to send to the application a stream including all of the data packets. For example, the MID sends to the application the data packets from the first interface, buffers the data packets from the second interface, and sends data packets from the buffer to the application upon detecting that data packets in the buffer were transmitted to the first interface but not received by the first interface.

Abstract: L'invention concerne des systèmes et des procédés de gestion de ressources et de résolution de conflits lors de l'enregistrement local d'actifs multimédia provenant d'une pluralité de sources dans des systèmes de distribution multimédia. Des ressources locales et système telles que mémoire, syntoniseur et bande passante sont prises en considération lorsque des sources alternatives d'actifs sont disponibles (par ex. VOD). Plutôt que d'enregistrer des actifs localement, si des actifs équivalents sont disponibles par l'intermédiaire de sources alternatives, les enregistrements sont différés et un pointeur de l'actif équivalent est enregistré à la place de l'actif. Lorsqu'un utilisateur sélectionne un actif multimédia pour la lecture, une session source <= sur demande >= ou alternative est déclenchée pour l'actif associé au pointeur. Avant la date d'expiration de l'équivalent de la source alternative de l'actif multimédia, celui-ci peut être téléchargé et enregistré localement. Le système peut déterminer automatiquement s'il doit enregistrer des actifs ou des pointeurs sur la base de divers facteurs tels que bande passante de transmission, latence et DRM.
