Patent CA-2212414-A1 (CA)
Title: Feedback controlled drug delivery system
Inventor: GORIN MICHAEL MORDUCH
IPC: A61M1/02
Filed: 1996-01-30
Abstract: A feedback controlled drug delivery system includes automated blood sampling and analysis and dosing of the patient. Automated sampling is performed by direct analysis of patient blood, such as for measurement of its coagulation state. A novel manifold includes a fluid input port, a patient port adapted to output fluid and to receive a blood sample from the patient, and a fluid pathway connecting the fluid port and the patient port. A sample line is connected to the fluid pathway to provide the sample to an analyzer. In one aspect of this invention, the sample is forced through the sample line by isolating the patient port, such as by a valve, and non-drug fluid is forced into the manifold causing the blood to cross through the sample line. In another embodiment, an integrated assembly includes an integrated peristaltic pump, valve assembly, selectively movable actuator and integrated waste container. In one aspect, the peristaltic pump permits retraction of the rollers away from the inner circumference of the pump, so as to reduce deformation of the peri-pump tube and to permit sterilization.

Title: Systems and methods for making time-sequential measurements of biological events
Inventor: SWANSON DAVID K
IPC: A61B5/308
Filed: 1996-02-14
Abstract: Analog or digital systems (10) and methods generate a composite signal derived from a biological event in a time sequential fashion. A first set of signals derived from a biological event using a first group of sensors (20) during a first time interval is input.     A second set of signals derived from the biological event during a second time interval sequentially after the first time interval using a second group of sensors (36) is input. The second group of sensors has at least one common sensor that is part of the first group and other sensors that are not part of the first group. The first and second sets of signals are time aligned using signals sensed by the at least one common sensor, thereby generating the composite signal. The time alignment is done by shifting the first and second sets of signals either with or without computing a time difference between them.

Title: Electric current switching apparatus with tornadic arc extinguishing mechanism
Inventor: MOLDOVAN PETER K
IPC: H01H50/00
Filed: 1997-10-03
Abstract: A contactor for switching electric current has a stationary contact and a movable contact which when driven by a solenoid moves into and away from abutment with the stationary contact.  An arc extinguishing chamber is adjacent to the movable and stationary contacts and includes two rows of splitter plates with a gap therebetween.  Each row comprises alternating splitter plates of first and second types.  The first type of splitter plate has a first member of non-magnetic material with an aperture within which a permanent magnet is received and a second member of a magnetic material abutting the first member remote from the gap.  An outer casing of a non-ferrous, electrically conductive material extends at least partially around the first and second members.  The second type of splitter plates are formed of non-ferrous, electrically conductive material.          The magnets produce a magnetic field around each of the first type of splitter plates which causes the electric arc to move about the surface of the outer casing.

Title: Optical fiber connector housing
Inventor: WALTERS MARK D
IPC: G02B6/44
Filed: 1997-11-19
Abstract: An optical fiber connector housing for facilitating the cross-connection or interconnection of optical fibers is provided having upper and lower plate members, a connector panel, a movable door and a means for releasably securing the door in a closed position. The upper and lower plate members are generally horizontal and spaced apart from one another with the front edge of the lower plate member extending further forward than the front edge of the upper plate member. The connector panel depends generally vertically downward from the front edge of the upper plate member thereby defining a shelf portion at the forward part of the lower plate member. The connector panel is adapted for mounting therethrough a plurality of optical fiber adaptors for receiving and mounting pairs of optical fibers in optical alignment. The door is hingeably connected to the front edge of the lower plate member and is moveable between an open and closed position. When in the closed position, the door has a generally vertical orientation and is vertically aligned with the connector panel thereby defining a forward cable area, at least one side aperture, and at least one top aperture. When the door is connected in the closed position, optical fibers to the front side of the connector panel can be advantageously routed out of the forward cable area by routing the first portion of the plurality of fibers through at least one side aperture and routing a second portion of the plurality of fibers to at least one top aperture, thereby reducing the density of optical fibers routed in each direction while the door protects the forward cable area from damage and maintains the minimum required bend radius.

Title: Mobile communication network for switching between communication systems
Inventor: HOMMA HIROKI
IPC: H04W48/16
Filed: 1998-02-24
Abstract: When a mobile communication terminal unit is using a particular one of a plurality of systems, the mobile communication terminal unit determines whether or not there is a higher priority system than the current system (at step 102).          When there is a higher priority system, just before starting monitoring the higher priority system, the mobile communication terminal unit informs the current base station of the monitoring process for the higher priority system and requests the base station to suspend a call to be sent to the mobile communication terminal unit (at step 103).  The mobile communication terminal unit monitors the higher priority system and records the monitored result (at step 104).  After having monitored the higher priority system (at step 105), the mobile communication terminal unit informs the current base station of the restoration to the current system and requests the base station to cancel the suspension of a call to the mobile communication terminal unit (at step 106).

Title: Shoe with circular pad in the sole to relieve twisting stresses on the knee
Inventor: GOLDBERG JACK
IPC: A43B5/02
Filed: 1996-10-09
Abstract: The invention relates to a sole for footwear having a structure for minimising injury to the wearer from twisting or turning movements which may occur during sporting activities, and/or for enhancing performance by assisting rotational movement of the foot. A first invention is a shoe sole (2) comprising a turntable (6) within the sole and connected thereto by a resilient web (30) which provides a seal between the periphery of the turntable and sole. The web is resiliently deformable in response to rotation of the turntable in either direction from a rest position to apply resilient bias to restore the turntable towards its rest position. There may be additional biaising means. There are ten further disclosures of the turntable involving: using glue to fix the turntable and to provide the seal and resilient bias; a separate turntable habing a wiper seal with the sole and addtional biasing means; means for limiting the extent of the rotational movement; coil and leaf springs and interengaging portions of the sole and turntable to provide the resilient bias; a circular race of ball bearings to support the turntable; multiple turntables; means for fixing cleats or studs to the turntable. A second invention is a sole having annular rows of deformable fins which permit limited rotation of the sole.
