Patent CA-2274268-A1 (CA)
Inventor: CZAJKOWSKI JULIAN
IPC: G05G5/03
Filed: 1999-06-08
Abstract: A pedal assembly includes a housing (16) and a pedal arm (14) pivotally connected to the housing (16) with a first end supporting a pedal pad (12) and a second end forming a pedal pivot arm (26). The pedal pivot arm (26) has at least one cam lobe (38) extending therefrom and the housing (16) has a cylindrical collar portion (30) recessed in the housing (16) for receiving and retaining at least one coil spring (24). The interaction of the spring (24) between the pedal pivot arm (26) and the collar portion (30) generates a hysteresis effect. The collar portion (30) has a notch (32) extending through the side wall of the housing (16). The coil spring (24) has a first distal end (34) seated in the notch (32) and a second distal end (36) that is in bias contact with the cam lobe (38). The coil spring (24) is forced into frictional contact with the side wall of the collar portion (30) when the pedal arm (14) is pivoted from a rest position to an operative position to reduce the spring force of the coil spring (24) on the pedal arm (14).

Title: Method of controlling cache memory in multiprocessor system and the multiprocessor system
Inventor: AINO SHIGEYUKI
IPC: G06F12/10
Filed: 1999-10-28
Abstract: Cache control protocols can be switched during running without changing an architecture for a segment descriptor or page descriptor for indicating an attribute of an area to be accessed. A plurality of processors each including a cache memory constitute a multiprocessor system which shares a main memory via a system bus. Each processor has module detecting means for detecting execution of a module which accesses a shared memory area on the main memory, by comparing the virtual space number and the instruction segment number concerning the accessing module with those numbers concerning the software modules preset which may access the shared memory area. Memory access executed in a module detected by the module detecting means is controlled in a cache control protocol of a store-through scheme which updates a main memory simultaneously with update of a cache memory. Memory access executed in other modules is controlled in a cache control protocol of a store-in scheme which does not update a main memory at update of a cache memory.

Title: Hatch for preventing fall-through and unauthorized entry
Inventor: MCKERNAN TIMOTHY J
IPC: E02D29/12
Filed: 2000-01-20
Abstract: An access hatch comprises a frame, a grate, and a pull member pivotally coupled to the grate. The frame contains an access opening. The grate has a near side and a far side. The near side is coupled to the frame for pivotal movement of the grate between a closed and an open position. In the closed position, the grate lies substantially in the access opening of the frame and blocks at least a portion of the opening. In the open position, the grate is oriented away from the opening of the frame to allow access through the opening. The pull member has a proximal end and a distal end.      The distal end is pivotally coupled to the grate near the far side of the grate, such that the proximal end is moveable away from the grate from a rest position. The proximal end extends substantially to the near side of the grate when the proximal end is in the rest position. The proximal end is normally in the rest position when the grate is in the closed position. A worker, intending to open the grate, is prompted to stand at the near side of the grate and grasp the proximal end of the pull member, to pull the grate to the open position.

IPC: A61F5/44
Filed: 1998-11-18
Abstract: The ostomy system (10) includes a pouch (12) that is adhesively coupled to a mounting wafer (14). The mounting wafer (14) has a landing zone film formed of releasable plastic, and the pouch (12) has a face plate (50) with a resealable adhesive that secures to the landing zone of the mounting wafer (14). The landing zone of the mounting wafer (14) includes one portion that is immovable with respect to the body surface that the mouting wafer (14) is secured to, and another portion that is deflectable away from the body surface. The deflectable portion of the landing zone, also referred to as the floating landing zone, is sized for gripping between the fingers during pouch separation from the mounting wafer (14).  Gripping of the floating landing zone during pouch separation helps isolate the pouch separation force from the abdominal area underlying the mounting wafer (14).
