Abstract: An object tracking system is provided for tracking the removal of objects (41, 61, 181) from a location and the replacement of the objects (41, 61, 181) at the location. The system includes a radio frequency identification "RFID" tag (19, 34, 52, 61, 166, 231) attached to each of the objects (41, 61, 181) to be tracked and each tag (19, 34, 52, 61, 166, 231) has an antenna (22, 23, 37, 38, 54, 56, 76, 169, 187, 197, 219, 232). When activated, the RFID tag (19, 34, 52, 61, 166, 231) of an object (41, 61, 181) transmits a unique code identifying the object (41, 61, 181). A storage unit (81) is provided at the location and the storage unit (81) has a plurality of receptacles (83) configured to receive objects (41, 61, 181) replaced at the location. Each receptacle (83) has an associated antenna (87, 88, 134, 141, 149, 151, 173, 193, 199, 224) for activating the RFID tag (19, 34, 52, 61, 166, 231) of an object (41, 61, 181) in the receptacle and receiving the radio frequency transmitted code of the object (41, 61, 181). The antennae of the system can be capacitive plates (22, 23, 27, 38, 54, 56) for conveying the radio frequency transmissions (93) through capacitive coupling or inductive loops (173, 193, 197) for conveying the transmissions through the inductive coupling. A computer-based controller (67, 234) is coupled to the antenna of the receptacles (83) for receiving transmitted codes and determining based thereon the absence or presence and location of objects (41, 61, 181) within the storage unit (81).

Abstract: L'invention concerne un procédé et un enregistreur vidéo numérique (DVR) (20) permettant d'enregistrer des signaux vidéo en temps réel sur un disque (1) DVR. Le disque peut présenter des défauts (11, 12, 13) ponctuels bidimensionnels, mais le système de correction d'erreurs DVR, très puissant, permet de corriger des erreurs résultant de défauts ponctuels mineurs (11, 12). Afin d'examiner rapidement et efficacement si le disque recèle des défauts ponctuels importants (13), on évalue l'intégrité de pistes d'essai prédéterminées (2T) en fonction du signal de guidage. Si l'on découvre une piste d'essai défectueuse (2T2, 2T3), on poursuit l'examen des abords de ladite piste. Si le nombre de pistes touchées est faible, on peut enregistrer sur lesdites pistes. En revanche, si ce nombre est important, on inscrit lesdites pistes sur une liste de défectueux, laquelle est, de préférence, enregistrée sur le disque. Lors de l'enregistrement, les pistes figurant sur la liste de défectueux sont sautées.

Title: Beam laydown for hopped satellite downlink with adaptable duty cycle
Inventor: BERGER HARVEY L
IPC: H04B7/185
Filed: 2001-06-19
Abstract: A power gated variable hop cycle beam laydown (700) manifests itself as first cells (C, D) supported by a first hop cycle, second cells (G, H) supported by a second hop cycle, and transition cells (E, F) supported by a transition hop cycle. The transition hop cycle uses power gating to transition the laydown (700) from cells (C, D) operating at the first hop cycle to cells (G, H) operating at the second hop cycle. To this end, the transition hop cycle power gates its downlink beam for a portion of time needed to reduce interference between nearby (e. g., adjacent) cells.

Abstract: A papermaking felt comprises a woven ground fabric layer and a fibrous web accumulated on one side or on both sides of the ground fabric layer.     The ground fabric and the fibrous web are intertwined and made integral by needling. To maintain the three dimensional structure of the felt against the pressure to which the papermaking felt is continually subjected in a high speed papermaking machine, and thereby retain the felt's water-squeezing function over a long period of time, all yarns of the warp or weft, or a part of the distributed yarns of the warp or weft which composes the ground fabric layer, are replaced by straight yarns S so that the warp or weft themselves maintain the felt's dimensional stability. Alternatively, straight yarns may be additionally and evenly inserted along the warp or weft of the ground fabric layer.
