Title: Method for recovery of a computer program infected by a computer virus
Inventor: MANN OMRI
IPC: G06F11/14
Filed: 1992-05-22
Granted: 2005-04-12
Abstract: A recovery technique allows a computer program to be recovered from a program which has been infected with a computer virus. Prior to the program being infected, a unique fingerprint of the program is taken and stored along with data relating to the beginning portion of the program at a location separate from the program. A program thought to be infected is processed by generating a fingerprint of a string in the program utilizing the stored data. The fingerprint that is generated is compared with the stored fingerprint to determine whether or not the two fingerprints match. If the fingerprints match, the program is restored from the stored information and the string. If the fingerprints do not match, the value utilized to select the string can be incremented and the process repeated.

Filed: 1993-10-29
Granted: 1998-07-14
Abstract: A quadrature generator (975, 1075) for generating a pair of pulse trains maintai ned in perfect phase quadrature with one another. The quadrature generator (975, 1075) includes a feedback control loop for alteri ng the duty cycle of an oscillating signal applied to a master-slave flip-flop pair (450, 650) configured to generate a pair of pulse tr ains maintained in a relative phase relationship. The feedback control loop controls the duty cycle of the oscillating signal applied to the ma ster-slave flip-flop pair (54, 58) which, in turn, is determinative of the phase relationship between the pulse train pair generated by the master-s lave flip-flop pair (54, 58). When the pulse trains generated by the flip-flop pair (450) are beyond phase quadrature, a control signal genera ted by the feedback control loop alters the duty cycle of the oscillating signal applied to the flip-flop pair (450); to alter the phase relat ionship between the pulse trains of the pulse train pair.
Patent CA-2133803-C (CA)

Filed: 1994-10-06
Granted: 1999-02-02
Abstract: An apparatus and method for crushing clay to reduce the size of the clay to a uniform particle size distribution without generating a substantial percentage of undersized particles.  Oversized clay particles are fed to a first roller mill between a first pair of counter-rotating, adjacent, grooved rollers.  The particles exiting the first roller mill that have the desired particle size distribution are separated from the undersized and oversized clay particles exiting the first roller mill, prior to crushing the oversized particles in a second roller mill.  The oversized particles from the first roller mill then are fed to the second roller mill between a second pair of counter-rotating, adjacent rollers that are separated by a roller gap that is smaller than a roller gap of the first roller mill.  By providing grooves in the outer surfaces of at least the first pair of rollers, in the first roller mill, and by removing the on-size particles prior to sending the over-size particles to the second roller mill, about 85% to about 95% of the clay feed is crushed to the desired particle size.  It should be noted that the particle size distribution is set between a top screen and bottom screen, the product being recovered between the two screens, and the particle size distribution can be fixed by adjusting the roller gap between the rollers of one or more roller mills of the apparatus to achieve a specified particle size distribution.
