Patent CA-2106159-A1 (CA)
Inventor: HOSHIZAKI T BLAINE
IPC: A63B71/12
Filed: 1993-09-14
Abstract: A shin pad for use in ice hockey and possibly other sports is described.  The shin pad includes a lower brace element positionable along the front of the player's shin and securable to the player's lower leg, and an upper brace element positionable along the front of the player's lower thigh and securable thereto.  A shin shield is secured outside the lower brace element.  The lower and upper brace elements are pivotally connected to each other by pivotal connections on lateral and medial sides thereof, the pivotal connections being positionable on lateral and medial sides of the player's knee, in general alignment with the axis of the player's knee joint.  To restrict or prevent hyperextension of the knee, the shin pad includes stop means arranged to prevent rotation of the upper and lower brace elements beyond a selected maximum permissible extension angle.          To maintain protection when the knee is flexed, the upper and lower brace elements preferably include overlapping arcuate kneecap portions, one on each of the brace elements, arranged such that no gap between them when the knee is flexed.  As the stop means, the upper arcuate kneecap portion may come into contact with the shin shield when the maximum permissible extension angle is reached.         Further features of the invention will be described or will become apparent in the course of the following detailed description.

Title: Method and apparatus for adaptively thresholding grayscale image data
Inventor: KIDD ROBERT C
IPC: G06V30/162
Filed: 1992-04-24
Abstract: A method and apparatus for adaptively adjusting (e.g. thresholding) grayscale image data associates with each document image file (210, 212) a predetermined grayscale adjusting function (216) which can be used to threshold, contrast stretch and gray le-vel reduce the original gray level image of the document into a picture representation for display at workstations, the picture re-presentation yielding increased contrast of written and printed text viewed. The invention includes a method of generating a re-mapping function for use in converting near-photographic docu-ment image pixel gray level data lying in a first range of gray level values to higher contrast, background-suppressed pixel gray level data lying in a second more limited gray level range. Global docu-ment information, such as a histogram of all the document's origi-nal pixels, is used to generate at least one threshold gray level va-lue and to determine the shape of the remapping function on either side of the threshold. Preferably, the remapping function is implemented by a look-up table (216) addressed in accordance with the original pixel data.

Title: Computer memory protection
Inventor: ROGERS THOMAS J
IPC: G06F21/80
Filed: 1992-11-05
Abstract: A write protection device (10) prevents data from being written to selected portions of the hard disc of a computer. The write protection device is connected between the CPU of the computer and the controller for the hard drive. The write protection device monitors the read/write commands from the CPU to the controller. The address of each write command is compared with preselected address(es) stored in registers (12, 15) corresponding to the partition area and boot sector, and/or any other preselected address listed in a look-up table (160). In the event of a positive comparison, the write command is prevented from reaching the controller.  Individual sectors of the disc can be write protected while still permitting writing to other sectors, even within the same cylinder. Low level format commands can be detected and disabled separately from write commands.

IPC: H01P7/06
Filed: 1994-10-26
Abstract: A bandpass microwave filter (32) is constructed by use of a right cylindrical cavity resonator (10) wherein end regions  (22,  24)  of the resonator are tapered.   The tapering is accomplished by replacing end portions of a right cylindrical sidewall with frusto-conic sections (22, 24)  of side wall.   Each frusto-conic section joins a central cylindrical section (26) of the sidewall with a planar end wall  (14,  16).   Each of the end walls is provided with a coupling slot (28, 30) having dimensions substantially smaller than a half wavelength of the center resonant  frequency  of  the  resonator  so  as  to  be  a nonresonant slot.   The slots in the end walls may be coupled to rectangular waveguides (34, 36) which form input and output ports by which electromagnetic signals are applied to and extracted from the resonator.
Patent CA-2139137-A1 (CA)
Inventor: CLAUSEN SCOTT A
IPC: F16H61/08
Filed: 1994-12-22
Abstract: A method for controlling shifting of a powershift transmission of an agricultural vehicle in accordance with a boost pressure developed by a turbocharger of an engine associated with said vehicle. The turbocharger generates a turbo boost pressure which is indicative of the engine torque being produced by the engine at a given time. The turbo boost pressure is monitored by a sensor which generates a boost pressure signal in accordance with the sensed boost pressure. This signal is then modified in accordance with the sensed engine speed of the vehicle to produce a compensated turbo boost signal. The compensated turbo boost signal is compared against predetermined full-load and no-load turbo boost values to determine the percentage value of full-load boost pressure, and thus the load on the engine, at a given time. The percentage value is then used to help generate an appropriate duty cycle and time value for a pulse-width-modulated drive signal which is used to modulate the on-coming directional clutch into engagement at a desired rate of engagement dependent upon the load being experienced by the vehicle.
