Title: Transmission parking brake
Inventor: JOLLIFF NORMAN E
IPC: F16H63/48
Filed: 1993-01-07
Abstract: The present invention is a parking brake for a transmission or transaxle.  The parking brake includes a parking block made of a material stronger than the housing and having keyways for engaging and locking the shift keys of the transmission.  The parking block is located in recesses in the housing halves and is thereby prevented from rotating.  By engaging the non-rotatable parking block, the shift keys are prevented from rotating and thereby prevent the rotation of the shift shaft and transmission of that motion to the axles.

Patent CA-2095267-A1 (CA)
Title: Image enchancement apparatus using variable integration time per pixel
Inventor: TULI RAJA S
IPC: H04N5/353
Filed: 1994-04-18
Abstract: \     An apparatus which adjusts the sensitivity capability of a sensor pixel when the light input goes beyond its normal dynamic light range. The apparatus may use an adjustable strobe width and/or other methods to desensitize or sensitize the pixel when the signal is too high or too low respectively. The apparatus may also use a method by which incident light on the image is made to change instead of the strobe width. This invention also allows any non-linear output from any type scanner to be linearized. It allows subtle shades of grey, not normally viewed due to the "washing out" effects of very wide dynamic and intense input signals, to be displayed with greater clarity.

Abstract: RD-21,846 METHOD AND APPARATUS FOR PRE-PROCESSING CONE     BEAM PROJECTION DATA FOR EXACT THREE DIMENSIONAL COMPUTER TOMOGRAPHIC IMAGE RECONSTRUCTION OF A PORTION OF AN OBJECT                      ABSTRACT OF THE DISCLOSURE              An improved method and apparatus for pre-processing cone beam attenuation data to reconstruct a three dimensional image of a particular region of interest of an object by a process of inverse Radon transformation is described.  The number of required operations is substantially reduced by selectively retaining for further processing only that cone beam attenuation data acquired within a select closed region of the surface of the array detector wherein this region provides data corresponding to beams actually attenuated in passing through the region of interest of the object.  In this manner, unnecessary beam attenuation data is discarded at the earliest possible opportunity to expedite image processing.

Title: Magnetic projectile
Inventor: HARBIN JOHN J
IPC: A63B67/06
Filed: 1993-09-27
Abstract: ABSTRACT            Magnetic Projectiles are known to be thrown at game targets of magnetically  responsive material.    In  all  cases  the  rate  of adherence to  target  by  the  average person  is  very  low  and unsatisfactory.  In this invention, a flexible projectile has been adapted to be projected at a surface of magnetically responsive material comprising a flexible magnetic disk and a cyclindrical shaped, light weight, flexible, resilient, directional stabilizer extending  axially  from  the  rear  for  holding and  aiming  the projectile.  The magnetic disk has multiple permanent alternating North and South Poles induced on the impact side for optimal holding  power  on  the  target.    The  inventive  projectile  in combination with a suitable target provides a simple, novel and effective game with a high rate of adherence of projectile to target for the average person.   The projectile is also used in combination with a non-magnetic  reappliable  flexible  sheeting material for use with a magnetically responsive surface.
