Title: Dialysis machines with touch screen user interface
Inventor: WIKLUND MICHAEL EDWARD
IPC: G16H20/40
Filed: 1997-08-12
Abstract: A user interface (12) for a medical instrument such as a dialysis machine (10) is described which uses both a touch screen (14) and hard keys (16, 18 and 20) off of the touch screen (14) to effectuate a change in a parameter associated with the operation of the machine (10). The user interface (12) is connected to extracorporeal circuit (24), mounted above lower cabinet (22) of dialysis machine (10). After the user selects a new parametric value on the touch screen (12), the user presses a hard key (16, 18 or 20) to implement a verification routine to insure that the entered parameter is appropriate for a machine's (10), patient's treatment and the display on the touch screen (14).  If the verification procedure ends in a positive result, the user is prompted to press a second hard key (16, 18 or 20) to confirm the change, causing an additional verification check to be performed.
Patent CA-2276974-A1 (CA)
Inventor: MAZE HOWARD KEITH
IPC: A01M25/00
Filed: 1999-07-07
Abstract: A method of exterminating gophers uses a pest exterminating apparatus which comprises a tank for storing anhydrous ammonia and a supply line connected to the tank for dispensing the anhydrous ammonia from the tank. The supply line can be connected to a gas valve in a gas dispensing position or a liquid valve in a liquid dispensing position. An elongate wand having a flexible tube mounted on a free end is connected to a dispensing end of the supply line for insertion of the flexible tube into a gopher's burrow. A person holding the supply line is spaced from the ammonia being dispensed due to the elongate wand. In use, the person positions the tank adjacent a gopher's burrow and inserts the flexible tube into the burrow. A  lever on the dispensing end of the supply line allows a valve to be opened for dispensing a portion of the ammonia into the burrow. The tank may then be relocated adjacent another burrow.

Patent CA-2281318-A1 (CA)
Inventor: MCCARTHY JAMES J
IPC: A47L9/28
Filed: 1999-09-03
Abstract: A control circuit is disclosed for selectively energizing an electrical device, such as a central vacuum cleaning system motor, coupled to the control circuit via a pair of conductive wires with an operating voltage. The control circuit has a circuit for selectively supplying and withholding operating electrical power to the electrical device. A first current detector is connected to a control voltage and senses a current flow resulting from closure of a circuit connected to a control voltage in at least one wire of the pair of conductive wires. A second current detector connected to the operating voltage senses a current flow resulting from closure of a circuit connected to the operating voltage in at least one wire of the pair of conductive wires. A first switching device responsive to the first current detector disconnects the control voltage from at least one of the wires and connects the operating voltage to the conductive pair. A second switching device responsive to the second current detector maintains the operating voltage to the conductor pair. The second switching device is responsive to the second current detector to connect the operating power to the electrical device.

A spring (160, 162) is connected between the first and second orthotic device portions for urging the first orthotic device portion to return to its initial angular position relative to the second orthotic device portion. The orthotic device may be configured for use with an arm, leg, ankle, head, back, and other skeletal body parts.
Patent CA-2287303-A1 (CA)
Inventor: FITERMAN CHARLES
IPC: G06F9/44
Filed: 1998-04-29
Abstract: Techniques for providing interactive user interfaces for programming constructs. A programming construct is associated with one or more metaphors (837) that specify interactive user interfaces (807) for the programming construct. Thus, a programming construct may have a metaphor for a text-based user interface or for one or more different graphical user interfaces. The metaphor may be associated with a description of the construct such as that found in an abstract syntax tree (823), and the metaphor may obtain the information it needs to construct the interface from the description, so that the user interfaces automatically track changes in the programming construct.  Also included is apparatus for modifying the metaphor. In one implementation, a build form function (1407) is used to read the information needed to construct the construct's user interface from the construct's description and the metaphor is modified by modifying the build form function. In the implementation, parameter values received via the user interface are incorporated into an abstract syntax tree that represents the construct.

IPC: G01M3/04
Filed: 1999-11-08
Abstract: An insulating glass pane (1) comprises at least two glass plates (10, 12) which are spaced apart from one another, and an edge joining strip (14) which surrounds and joins together the glass plates (10, 12) in the region of their edges, in which the edge joining strip (14) seals and delimits an insulating cavity (16) which is located between the glass plates (10, 12), and in which the insulating cavity (16) is filled with a fill gas which is not air. A sensor (18) is provided in the insulating cavity (16) of the insulating glass pane (1), which sensor reacts and gives a signal if the composition of the fill gas changes.
Patent CA-2288788-A1 (CA)
Inventor: LI HONDI
IPC: G01T1/208
Filed: 1998-05-07
Abstract: Gamma cameras and positron (PET) cameras use scintillation detectors to detect radiation from the body. However, when the number of radiation particles that strike the detector is very high, the chance that signals from two or more individual particles will pile up in the detector (to produce one erroneous, larger signal) is high. This problem is common to all applications using scintillation detectors. The present invention discloses methods and apparatus to prevent and correct for this problem. Results from a circuit according to the present invention show at least a 10 fold improvement in the maximum detection-rate limit over the conventional method.

Title: Flexibly coordinated motion elliptical exerciser
Inventor: BIRRELL JAMES S
IPC: A63B23/04
Filed: 2000-03-06
Abstract: An exerciser (10) includes a floor engaging frame (14), towards the rear of which are attached left and right axle mount supports (22) and (24), that house a transverse axle (26). The axle (26) connects the left and right drive wheels (30) and (32). Rear portions of left and right foot link members (36) and (38) rollably engage the drive wheels. Front portions of the foot link members rollably engage left and right inclinable guide ramps (60) and (62). The inclinable guide ramps are biased rotationally upwardly, by a ramp return assembly (70) that causes one ramp to pivot downwardly as the other ramp pivots upwardly. Forward and rearward pulley and belt systems (72) and (76) are connected to the foot links and provide flexibly coordinated motion which substantially relates the movement of the first and second foot links to each other, while permitting some degree of uncoordinated motion between the foot links. When the foot link members reciprocate along the inclinable guide ramps, the interaction between the oscillating weight of a user and the upwardly biased guide ramps, causes the foot support portions to travel along elliptical paths.
Patent CA-2300157-A1 (CA)
Inventor: GANZ ZVI
IPC: H04L12/28
Filed: 1998-08-13
Abstract: A media control approach that supports transmission of data streams with QoS  requirements, such as minimum throughput or maximum delay, while adapting to the changing characteristics of the transmission medium. The media control approach includes use of a polling manager (324) and a resource manager (322).  The resource manager (322) provides an admission control procedure that prevents admission of sessions that cannot be supported by the system and allocates network resources needed to support admitted sessions. The polling manager (324) uses an efficient "just in time" polling of stations based on their allocated bandwidth or communication rates. Stations that do not use their allocated rates are polled less often than those which use their allocation, thereby increasing the total throughput of the system and providing proper quality of service support for real-time application.
