Filed: 1998-11-05
Abstract: L'invention porte sur un système d'injection pour angiographie et sur un procédé d'administration contrôlée d'un fluide médicinal à un patient au moyen de ce système. On utilise un système de commande à plusieurs processeurs pour commander activement le processus d'injection et contrôler les fonctions sensibles du système. Tous ces processeurs comportent des doubles circuits de sécurité de redondance destinés à des fonctions de commande critiques telles que le courant et la vitesse d'entraînement du moteur de la seringue. L'invention porte également sur une fonction de commande nichée du moteur/servo-amplificateur, ainsi que sur un procédé unique et un appareil permettant d'établir des valeurs par défaut des paramètres d'injection, juste avant de procéder à l'injection, à partir des valeurs physiologiques du patient à traiter. Le système d'injection utilise un panneau d'affichage interactif qui présente à l'utilisateur des images structurées séquencées, et qui permet à l'utilisateur de sélectionner des procédures d'injection, des paramètres et autres modes de fonctionnement directement par le panneau interactif.

Inventor: ZHANG ZIAOJUN
IPC: E02F3/815
Filed: 1999-12-17
Abstract: A method and apparatus for controlling a work implement moveably connected to a work machine. An implement controller automatically controls simultaneous first and second control modes of operation assigned to the work implement. A sensor applies a signal to the implement controller indicating position of the work implement. The implement controller reverses the simultaneous first and second control modes assigned to the work implement upon detecting a predetermined movement of the work movement. The implement controller also automatically moves the work implement from a first rotational position to a second, mirror image rotational position upon operator actuation of a manually actuatable device. The simultaneous first and second control mode assignments may also be changed by actuation of the manually actuatable device.

Filed: 1999-02-17
Abstract: An electrochemical cell (10) is disclosed, having a sealed prismatic housing (12, 14) with two opposing, internal side surfaces defining therebetween an internal cavity having width and length. One of the side surfaces defines an arc (20), and the other of the internal side surfaces defines a concave arc (26) opposing the convex arc of the one side surface. An electrode stack is contained within the internal cavity of the housing, having positive (32) and negative (30) electrode sheets arranged in face-to-face relation. The electrode stack is arranged between the side surfaces of the housing such that the stack is retained between the one side surface and the extending features of the other side surface, and deflected to follow convex arc (20) to maintain contact pressure between the positive (32) and negative (30) electrode sheets. The stack is thus stretched across an inwardly crowned surface of the housing. The invention can, by maintaining good intersheet contact pressure within the stack, provide good overall active material utilization (for high cell capacity) and can help to inhibit housing distension of cells with broad sides. Methods of construction are also disclosed.

Filed: 2000-01-18
Abstract: Disclosed is a low power time domain reflectometry radar (LPTDRR) level transmitter (100) for calculating levels of first and second products (14, 15) in a tank (12). A termination (110) extends into the first and second products (14, 15) in the tank. A pulse generator (210) transmits a pulse along the termination (110) into the first and second products (14, 15). A pulse receiver (220) receives first and second reflected wave pulses corresponding to reflection of a first portion of the transmit pulse at a first product interface (127) and reflection of a second portion of the transmit pulse at a second product interface (128), respectively. A threshold controller (230) generates a first threshold for detection of the first reflected wave pulse and a second threshold for detection of the second reflected wave pulse. A  dielectric constant calculator (240) determines a dielectric constant of the first product (14) as a function of the first reflected wave pulse. A level computer (250) calculates levels of the first and second products (14, 15).

Title: A differential bipolar stray-insensitive pipelined digital-to-analog converter
Inventor: MOUSSAVI MOHSEN
IPC: H03M1/72
Filed: 2000-12-04
Abstract: Stray-insensitive pipelined Digital-to-Analog Convert-ers (DACs) can be implemented without an opamp in each stage. The quasi-passive circuit designed in this method dissipates less power, runs faster, has better ac-curacy, and takes less area than the conventional stray-insensitive architecture. A pipelined DAC designed with a differential bipolar architecture achieves close to 13 bits of linearity at 17.664 MSps conversion rate, which makes it suitable for full-rate downstream DSL signals. The converter is designed in a 0.6-µ double-poly CMOS tech-nology and dissipates 43 mW.

Abstract: An intraurethral magnetic valve (1) for insertion in the human urethra of a person suffering from incontinence. The intraurethral magnetic valve (1) includes a nonferromagnetic cylindrical housing (2), a valve seat assembly (36) attached to one end of the housing, a spherical magnetic valve element (14) disposed for universal movement in the housing, and a ring (10) for retaining the valve element which is attached at the other end of the housing. The valve seat assembly (36) has a nonferromagnetic valve seat (4) and ferromagnetic ring (5). The valve element (14) is maintained in closed check position against the valve seat (4) by attraction to the ferromagnetic ring (5), restricting the flow of fluid through the valve (1). An external magnet (15) is used to impart magnetic torque and attraction to the valve element (14) displacing it from the valve seat (4) and opening the valve for fluid flow. On removal of the external magnet (15), the valve element (14) returns to its closed check position on the valve seat (4).  The intraurethral magnetic valve (1) may further include a mechanism (14) having a spring (134) for relieving excessive fluid pressure, in which the valve seat assembly (36), rather than being attached to the housing (2), is axially slidable within the housing against the force of the spring (134) when excessive hydrostatic pressure is present to allow release of fluid through a passageway around the valve seat assembly (36).
