Patent CA-2348985-A1 (CA)
Inventor: SMITH ROGER Q
IPC: B24B23/02
Filed: 2001-05-28
Abstract: A power tool with a shaft locking mechanism has a member which is rotatable about a pivot on the housing. The member has a first projection which rotates the member between an engaging and a disengaging position. A gear is secured to the output shaft of the power tool. In a first position, the member does not engage the gear. When the first projection is moved, the member rotates such that a second projection engages the gear. When the second projection engages the gear, this prohibits rotation of the output shaft. To disengage the member, the first projection is moved in the opposite direction which, in turn, disengages the second projection from the gear enabling rotation of the output shaft.

Abstract: A steerable wheel assembly for an in-line skate or roller ski comprises a hollow or dish-shaped wheel (11), a wheel bearing (13), and a wheel support (14) connecting the wheel (11) to a steering pivot (16) which is substantially disposed at a distance measured radially from the rotational axis of the wheel (11) where that distance is greater than the outer radius of the wheel bearing (13) and less than the outer radius of the wheel (11). Steering of the wheel occurs as the user's weight is displaced or the chassis of the device is inclined with respect to the ground toward the desired turning direction. A  chassis for an in-line skate or roller ski containing a damping and centering force mechanism which may be used to moderate the behavior of a steering mechanism or suspension mechanism comprises a structural member (21), a damper housing (17), a damper piston (19), a fluid chamber (24), and a centering force means (18).

Title: Elevation bed
Inventor: SEABROOK WILLIAM J
IPC: A47C17/84
Filed: 2001-06-14
Abstract: This invention discloses an electrically driven elevation bed which, improves the utilisation of both floor and wall space. The elevation bed includes an improved driving system, which allows the driving system to be detached from the bed and independently returned to its raised position leaving the mattress frame on the floor free of attachment to allow it to be easily moved to where required. This allows the apparatus to be mounted away from the walls leaving them free for other usage. The driving system also includes a sub system that repositions the support legs of the bed as the mattress frame is raised to its elevated storage position so that the raised profile of the complete apparatus is of minimal proportion. The mattress frame of the elevation bed includes an improved system for positioning the mattress such that the bed can be used for other usages.

Title: Method and apparatus of automatically identifying faults in a machine vision measuring system
Inventor: GLICKMAN STEPHEN
IPC: G06T1/00
Filed: 2000-12-07
Abstract: An apparatus and method for automatically identifying faults in the operatio n of a machine vision measuring systems provides an improved self-diagnostic capability for machine vision based metrology and tracking systems. The meth od and apparatus validate performance of tracking operations, and detect deterioration that may be caused by electronic noise, environmental contamination, etc. A mathematical model of the target visualized by the system is created and stored. A target is imaged in the field and fiducials of the target are identified. Centroid positions of detected fiducials of the imaged target are compared to the centroid positions of fiducials in the mathematical model. When a fiducial is obscured or dirty, its geometric characteristics (such as centroid, brightness, edge smoothness, area, or shape) differ from the true or idealized values of the characteristics. Valu es representing detected fiducials are discarded when the offset exceeds predetermined criteria, or when its properties vary from ideal. If the remaining number of detected fiducials is below a predetermined threshold, a  warning message is displayed or an error is generated. Thus, when a fault is  detected that degrades performance beyond a preset tolerance, the fault is flagged for attention and a suggested corrective action is displayed.</SDOAB >

Inventor: BAILEY KENNETH S
IPC: G06F21/32
Filed: 1999-12-08
Abstract: A secure system using a continuously-changing key that depends on the user's body part. A system obtains an image of the user's fingerprint (105) and cements it according to a random generator (104). Only part of the image and not the entire image is sent atone time. The random segmentation insures that part of the image that is sent continuously varies from time to time. Therefore, an unauthorized receiver can receive only part but not the entire image. The fingerprint image part is verified by a remote agent (120).

Title: Grooved construction beam
Inventor: CHARLAND GILLES
IPC: E04B2/74
Filed: 2001-08-15
Abstract: A construction beam defining a pair of lateral surfaces and s pair of abutment surfaces. The beam defines a set of alternating grooves and intermediate segments extending between the grooves. When the abutment surfaces are abuttingly positioned against other surfaces, the grooves being filled with air provide vibration dampening and thus reduced noise transmission. The air-filled grooves also provide thermal insulation. The configuration of the grooves allows trough flow of air reducing the risks of trapping moisture that could lead to rotting.      The intermediate segments are optionally made of resilient material.

Title: Parallel processing system
Inventor: SAVAGE JAMES R
IPC: G06F9/06
Filed: 1990-09-28
Abstract: A parallel processing computer system is described. The system includes an arbitrarily large number of processing elements hierarchically connected to each ether. In operation, when a program executes a parallel do instruction statement, parallel tasks are created, one for each iteration of the parallel do instruction. Each newly-created task is the child task of the task that executed the parallel do statement.      Each child task inherits the memory state of the parent task, and while each child task executes, the parent task is suspended. When the child tasks complete, their memory states are merged to form the new memory state of the parent task which then resumes execution.
