Patent CA-2186700-A1 (CA)
Title: An implantable atrial defibrillator having cardioverting output voltage limiting for simulating larger storage capacitors
Inventor: WAGNER DARRELL O
IPC: A61N1/39
Filed: 1996-09-27
Abstract: An implantable atrial defibrillator includes a storage capacitor for storing electrical energy.  A switch discharges at least a portion of the stored energy into a patient's heat as a discharge voltage and a charger charges the storage capacitor with the stored energy to a peak voltage.  A voltage limiter precludes the discharge voltage from exceeding a voltage limit during capacitor discharge to permit a reduced applied cardioverting voltage with a lengthened discharge time.  The voltage limit is a substantially constant fraction of the peak voltage.

Title: Multi-lumen catheter system
Inventor: LOGGIE BRIAN W
IPC: A61M25/00
Filed: 1995-03-31
Abstract: A catheter system (10) facilitates blood treatments such as apheresis that require simultaneous withdrawal and return of blood to a patient at high flow rates. A multi-lumen catheter (12) has an external coupling device (46) connected to a pump (14) and blood treatment device (16). The catheter (12) includes two or more lumens (24, 26 28) for withdrawing blood and a return lumen for returning treated blood. The combined flow resistance of the withdrawal lumens (26, 28) is less than or equal to the flow resistance of the return lumen (24) so that the flow rate of blood through the withdrawal lumens (26, 28) does not require a pressure differential sufficient to collapse the lumens. High flow rates are achievable through the catheter by using a pair of withdrawal lumens (26, 28) instead of a single, large withdrawal lumen.

Title: Method of making a bearing structure and bearing so made
Inventor: LUZSICZA STEVEN O
IPC: F16C27/06
Filed: 1995-05-08
Abstract: A steel inner tube (40) and thermoplastic outer tube (42) are placed in an injection mold apparatus and a thermoplastic intermediate tube (44) is molded between the inner (40) and outer (42) tubes. The intermediate tube (44) shrink fit locks to the inner (40) tube and shrinks relative to the outer tube (42) to provide a selected journal-bearing torque relation therebetween. Projections and mating recesses (62) on the inner tube (40) and intermediate tube (44) facilitate locking the intermediate tube (44) to the inner tube (40) without adhesives or other bonding agents. One or more thrust rings (58) and recesses (66) are formed on the mating surfaces of the outer tube (42) and intermediate tube (44) to preclude axial relative displacement therebetween in response to axial thrust loads. An elastomeric tubular member (46) (or other known bushing construction) is secured over the outer tube (42) and an outer steel tube (48) is over the elastomeric member (46) to provide an enhanced control arm bushing with a predetermined torque response for automotive suspension systems.

Title: Methods for selectively stimulating proliferation of t cells
Inventor: JUNE CARL H
IPC: A61K39/00
Filed: 1994-12-01
Abstract: Methods for inducing a population of T cells to proliferate by activating the population of T cells and stimulating an accessory molecule on the surface of the T cells with a ligand which binds the accessory molecule are described. T  cell proliferation occurs in the absence of exogenous growth factors or accessory cells. T cell activation is accomplished by stimulating the T cell receptor (TCR)/CD3 complex or the CD2 surface protein. To induce proliferation of an activated population of T cells, an accessory molecule on the surface of the T cells, such as CD9 or CD28, is stimulated with a ligand (e.g. monoclonal antibody ES5.2D8) specific for CD9 which binds the accessory molecule. The T  cell population expanded by the method of the invention can be genetically transduced and used for immunotherapy or can be used in methods of diagnosis.

Patent CA-2198819-A1 (CA)
Inventor: MUELLER MICHAEL ALLEN
IPC: G05G9/047
Filed: 1997-02-28
Abstract: A hydraulic pilot valve has a joystick which is normally maintained in a neutral position by coil springs acting on plungers which engage corresponding first cam surfaces of a cam fixed to the joystick. The plungers are each connected to respective valve members which are stroked to open the pilot valve when the plungers are depressed. When the joystick is pivoted to depress one of the plungers by engaging the head of the plunger so as to stroke one of the valve members, that valve member is held stroked by an magnetic detent. The joystick may then be released and the valve member will remain in its stroked position. When the joystick is moved back towards a neutral position, a second cam surfaceon the joystick engages an outer end portion of the depressed plunger and applies an axial force to the plunger. This disengages an armature component of the magnetic detent from an electromagnetic component. A spring then pushes the plunger to its neutral position where the plunger holds the valve member operated thereby closed. In accordance with one embodiment, one joystick operates four valve members and, in accordance with another embodiment the pilot valves are stacked. When the joystick operates four valve members, a spring biased sliding cam is mounted on the joystick for engaging the end surfaces of the plunger heads. A cam having four raised, arcuate cam surfaces is fixed to the joystick for engaging frustoconical sides of the plunger heads so that the plunger heads can be trapped between the sliding cam and raised cam surfaces to minimize slop.

Filed: 1997-03-03
Abstract: An automatic distribution system for the drugs' sale with prescription, for the patients being in particular situations: over the night, in far-away localities or in the places where to install a classical pharmacy is not economically justifiable. The automatic drug distribution system includes a network of distributing stations related to a regional control center where a group of chemists are available permanently to realize the professional act required by every patient who accedes to such a distribution station. An interactive and reciprocal communication by video, phone and writing is established between patient and chemist, using a telephone line or a radio frequency, as a function of the economical communication means available in the respective zone. The patient identification, as well as the prescription interpretation, are assured by the "reading" of the medical card and prescription, using a scanner. The standard professional act, consisting in the opening, registering or transferring of the patient file, is realized by the same ordinary dialog between chemist and patient, using the same informational means. The payment and drug delivery from the standard stock of the distribution station, are automatically realized after the transaction's acceptance. The standard stock of the distribution stations is periodically restored by replacement of the individual cases where the drugs are consumed.

IPC: H04L12/46
Filed: 1995-10-25
Abstract: A switching fabric circuit that provides on-the-fly switching of packets, an expandable number of ports, and the interconnection of heterogeneous LAN segments. The switching fabric circuit includes a switching link that comprises a switching bus and a plurality of packet processors, wherein each packet processor is coupled between the switching bus and a LAN segment. The switching bus is a time division multiple access (TDMA) bus, and arbitration for switching bus access is distinct from arbitration for access to the ports of the switching fabric circuit. Switching bus arbitration is done according to one of two priority levels, wherein high priority requests are guaranteed access to the switching bus during a synchronization period in which the high priority requests are made. This provides for guaranteed throughput and on-the-fly switching of packets. Port arbitration may be either uniport port arbitration or multiport port arbitration. Port arbitration is characterized by the transmission of a POE mask by a source port to a destination port and by the subsequent transmission of a DPA signal by the destination port to the source port.
