Patent CA-2145189-A1 (CA)
Title: Active low temperature limit for battery powered thermostat
Inventor: RATZ JAMES W
IPC: G05D23/19
Filed: 1993-11-19
Abstract: A low temperature limit for battery powered thermostats for energizing and de-energizing the heating system when the bat-tery (15) can no longer operate the thermostat (1). The thermostat (1) comprises a battery powered thermostat control (10) for en-ergizing and de-energizing the heating system and a low temperature limit (24) electrically connected in parallel with the battery powered thermostat control (10). The battery powered thermostat control (10) disables a controllable switch (20) and, thereby, the low temperature limit bimetal switch (24) when the battery is charged. When the battery (15) is discharged, it enables the low tem-perature bimetal switch limit (24). Thereby, when the thermostat is no longer operational, the low temperature limit (24) energizes the heating system when the ambient temperature present on the thermostat (1) is below a preselected temperature.

Patent CA-2157963-A1 (CA)
Inventor: BAGHDASARIAN VAROUJ G
IPC: H01Q1/28
Filed: 1995-09-11
Abstract: Deployment hinge apparatus comprises a stationary U-shaped bracket including a flange defining a retention recess. A hinge arm for supporting an operating structure such as a communication antenna reflector is pivotally mounted on the stationary bracket for movement between a stowed position and  a deployed  position.  The  hinge  arm  includes  a deployment and latching cam which extends to a projecting nose member. A latch arm is pivotally mounted at one end to the stationary bracket and includes a cam follower at its other end operatively engageable with the cam. A spring biases the cam follower into engagement with the cam and is thereby effective to rotate the hinge arm from the stowed position  to the  deployed position  such  that,  in  the deployed position, the nose member and the cam follower are together snugly received in the retention recess, locking the hinge arm in the deployed position. In a simplified embodiment, which does not utilize a latch arm or a cam and cam follower, a bearing pivotally mounts the hinge arm on the stationary bracket. A first stop member is provided on the stationary bracket and a second adjustable stop member is provided on the hinge arm positioned to engage the first stop member when the hinge arm is in the deployed position. A spring biases the hinge arm toward the deployed position with the second stop member engaged with the first stop member and is effective to retain the hinge arm in the deployed position.

Patent CA-2168335-A1 (CA)
Title: Virtual addressing buffer circuit
Inventor: KIM JASON SEUNG-MIN
IPC: G06F12/10
Filed: 1994-10-04
Abstract: A virtual addressing buffer circuit (10) formats an output address utilizing a format register (16) as a combination of new address bits and original input address bits. The ability to format the output address enables the user to replace certain address bits without requiring that the entire address be replaced. The virtual addressing buffer controls the output of several command signals to external circuits to indicate how the system should respond to the address output from the virtual addressing buffer. The command signals are controlled by a command register (20) and are output from the virtual addressing buffer only when an address match has been verified. The virtual addressing buffer circuit filters out certain bits of an input address as indicated by a filter register (22) before it verifies that the input address matches a stored address. Once an address match has been detected, the virtual addressing buffer circuit replaces the entire input address with a new formatted address.

Inventor: EBENSTEIN SCOTT M
IPC: B60K20/02
Filed: 1996-08-20
Abstract: A shifter for a vehicle includes a base for attachment to the vehicle, and a transmission shift lever having a slidably connectable pivot for pivoting shift lever to the base. The base includes configured sidewalls defining opposing sockets having a first diameter and inlets to the sockets having a first width less than the first diameter. The shift lever includes an integrally molded pivot member with protruding flat-sided rod sections. The rod sections define a second diameter about equal to the first diameter, and the flat sides of the rod sections define a second width about equal to the first width. By positioning the shift lever in an assembly-permitting angular position, the flat sides align with the inlet and the pivot member can be slid through the inlets into releasable pivotal with the sockets. When the shift lever is pivoted from the assembly-permitting angular position to a plurality of gear shift positions, the flat sides of the rod sections are pivoted out of alignment with the inlets such that the shift lever is non-releasably pivotally retained in the sockets. A method includes slidably engaging the pivot members on the shift lever into the sockets in the base, and pivoting the shift lever from an assembly-permitting angular position to the gear positions to retain the shift lever in the sockets.

Title: Method of forming medical devices; intravascular occlusion devices
Inventor: MAZZOCHI RUDY
IPC: A61B17/00
Filed: 1995-07-10
Abstract: The present invention provides a method of forming a medical device and medical devices which can be formed in accordance with the method. In one embodiment, the method includes the steps of: a) providing a metal fabric formed of a plurality of strands formed of a metal which can be heat treated to substantially set a desired shape; b) deforming the metal fabric to generally conform to a surface of a molding element; c) heat treating the metal fabric in contact with the surface of the molding element to substantially set the shape of the fabric in its deformed state; and d) removing the metal fabric from contact with the molding element. The resulting metal fabric will define a medical device which can be collapsed for passage through a catheter or the like for deployment in a channel of a patient's body. Medical devices made in accordance with this method can have varying structures. In one embodiment, the medical device (250) is carried by a guidewire (260) and has a metal fabric (270) extending between first and second ends (272, 274), one end (274) of the device (250) being adapted to slide along the guidewire (260). The metal fabric (270) has a collapsed configuration in which the ends (272, 274) of the metal fabric (270) are spaced from one another along the guidewire (260) and a preset expanded configuration in which the ends (272, 274) of the metal fabric (270) are positioned closer to one another. The metal fabric (270) will cause the device (250) to elastically substantially resume its preset expanded configuration when released from confinement within a channel in a patient's body.
