IPC: B60P7/135
Filed: 1995-08-18
Abstract: An article carrier (10) includes spaced longitudinal rails (18, 20), at least one of the rails having an upper arm (30, 32) coupled by a hinge (39) to a lower arm (34). A crossbar (22) having an end portion (24) adapted to be entrained between the upper (30, 32) and lower arm (34) portions includes a conformingly shaped mating surface (44) to one of the members of the longitudinal rail (34). Preferably, both ends (24) of each cross bar (22) include conforming surfaces (44) that mate with corresponding configurations on the rail to fixedly position the crossbar (22) along the longitudinal rail (34). The position of the crossbar (22) is easily adjusted by opening the upper member (30, 32) of the longitudinal rail (34) by displacement about the hinge (38), and the hinge axis may be transversely, longitudinally or vertically aligned as desired. Preferably, two upper arms (30, 32) are provided on a longitudinal rail (34), hinged at opposite ends (24) of the longitudinal rails (34), and include overlapping portions retained by a single latch mechanism. In addition, the crossbar (22) preferably includes a retainer that engages a lip in the lower arm (34) of the rail so that the lower arm resists lifting of the crossbar (22) from the rail.

Abstract: A laser rangefinding system (12) that utilizes multiple pulse, multiple return, modal range processing for clutter rejection.  A laser source (16) emits a series of laser beam pulses (42), and each reflected return from objects  (46)  in  a  scene  for  each  of  the  pulses  is recorded.    Each  return  signal  above  a  predetermined threshold is added as a count to a count table within a selected bin representing the range of the return signal. After all of the analog return signals are recorded, the range bin with the most counts is selected as the range of a target.

IPC: G10L25/78
Filed: 1996-01-25
Abstract: Un premier vocodeur à distance (15) reçoit de la voix analogique (170) et génère des données de codage groupées par paquets (190) qui sont transmises par liaison sans fil (20). Un premier vocodeur local (35) reçoit les données de codage groupées par paquets (190) de la liaison sans fil (20). Le premier vocodeur local (35) convertit les données mises en paquets (190) en sortie MIC multibits (120). Le premier vocodeur local (35) ajoute également un code de détection à un des bits de poids faible (LSB) de la sortie MIC (210). Le premier vocodeur local (35) retransmet le signal MIC (210) au RTPC (40). Le premier vocodeur local (35) reçoit également l'entrée MIC (120) par le RTPC (40). Le premier vocodeur local (35) surveille en permanence le bit de poids faible de l'entrée MIC (120) à la recherche d'un code de détection indiquant qu'un deuxième vocodeur local (55) est connecté côté réception. Dès que le premier vocodeur local (35) détecte le code de détection du deuxième vocodeur local (55), il commence à remplacer les données mises en paquets et procède à un contrôle de redondance pour un deuxième bit de faible poids de la sortie MIC (210). Le premier vocodeur local (35) commence également à surveiller le deuxième bit de faible poids de l'entrée MIC (120). Si le contrôle par redondance indique que des données en paquets valables ont été reçues, le premier vocodeur local (35) arrête de convertir la sortie MIC (120) en données groupées par paquets et les retransmet simplement sur le deuxième bit de faible poids au premier vocodeur à distance (15) en tant que paquets (100). S'il arrive que le contrôle par redondance échoue et que le code de détection ne soit pas détecté, le premier vocodeur local (35) reprend la conversion des entrées MIC (190) en données groupées par paquets, ce qui permet de contourner le dispositif de codage de la voix en tandem.

Patent CA-2216209-A1 (CA)
Inventor: KRAUSE KENNETH W
IPC: H02P6/20
Filed: 1996-04-11
Abstract: Un système chirurgical, adapté pour fonctionner avec au moins un instrument chirurgical, comprend une pièce à main avec un moteur qui est conçu pour recevoir l'instrument chirurgical. L'instrument chirurgical est entraîné sans discontinuité par une succession de positions, par l'arbre du moteur. Un microprocesseur de commande (16) gère le fonctionnement du système. Le moteur a des détecteurs pour générer des signaux électriques de position (22) et le microprocesseur de commande (16) réagit aux signaux reçus pour définir aussi bien une position d'arrêt qu'une position d'inversion de l'instrument chirurgical. Dans ces conditions, le microprocesseur de commande (16) commence une opération de l'instrument chirurgical à la position d'arrêt et interrompt le fonctionnement de l'instrument chirurgical pour qu'il s'arrête sensiblement à la position d'arrêt. Dans un mode de fonctionnement oscillatoire, le microprocesseur de commande (16) impose également des inversions uniquement à la position d'inversion dictée par le système, sous la commande de l'utilisateur. Dans le cas où l'instrument chirurgical est un instrument chirurgical arthroscopique, le microprocesseur de commande permet au chirurgien de choisir, par exemple, la taille de l'ouverture à travers laquelle le tissu et les fluides sont évacués hors du site de l'intervention pendant les opérations d'inversion et ou de démarrage/arrêt.

Title: Front mounted rake
Inventor: LUTZ HENRY
IPC: A01D75/00
Filed: 1997-10-28
Abstract: A front mounted rake includes a primary support, a first arm and a second arm.  Tine wheels are mounted each of the arms. The first end of each arm is secured for pivotal movement about  both  a  substantially  vertical  axis  and  about  a substantially horizontal axis to the primary support.   The second end of each arm is supported by ground engaging wheels. A brace maintains the relative lateral spacing of the arms. The pivotal movement of the second arm about the substantially horizontal axis is independent of the pivotal movement of the first arm about the substantially horizontal axis thereby permitting the first arm and the second arm to independently raise and lower as the ground engaging wheels travel over ground contours.

Title: Fast fourier transforming apparatus and method, variable bit reverse circuit, inverse fast fourier transforming apparatus and method, and ofdm receiver and transmitter
Inventor: NAKAI YUJI
IPC: G06F17/14
Filed: 1998-01-21
Abstract: In fast Fourier transform, a necessary memory capacity is decreased,  thereby  decreasing  a  cost.    The  fast  Fourier transform is performed on a symbol stored in a RAM by a butterfly operation unit in accordance with a RAM address generated by a RAM address generator.  A RAM address conversion unit  converts  an  input/output  dummy  address  into  an input/output real address  by conducting bit reverse by a frequency specified in accordance with an input/output bit reverse  signal,  and converts  a  butterfly operation  dummy address into a butterfly operation real address by conducting the bit reverse by a frequency specified in accordance with a butterfly operation bit reverse signal.  In this manner, among output data of one symbol and input data of another symbol to be stored in the RAM subsequently to the output data of the one symbol, data having a common index indicating their orders in the symbols can be stored at the same address in the RAM.  As a result, symbol input and symbol output can be overlapped.

Abstract: L'invention est un nouveau système de radiocommunication (SYS) basé principalement sur les technologies actuelles qui utilise des dispositifs radio stationnaire et mobile (DBS; MMS) construits en technologies standard. Ces dispositifs radio sont modifiés de telle façon que, pour établir la liaison radio entre eux, l'un d'eux au moins (MMS) transmet en sens opposé à celui spécifié par le protocole radio (PGSM) l'un des signaux radio (FB) qui est sensé être transmis par l'autre (DBS). Par exemple, le signal radio (FB, salve de correction de fréquence) qui n'est sensé être transmis que dans la direction descendante (DL, liaison descendante) est ici transmis dans la direction ascendante (UL, liaison ascendante). Ce changement ne nécessite qu'une modification des logiciels de commande de l'émetteur du dispositif radio mobile et du récepteur du dispositif radio stationnaire.
