Title: A method and apparatus for management of faulty data in a raid system
Inventor: BHASKAR ASHOK
IPC: G06F11/16
Filed: 1996-12-11
Abstract: When a read error occurs during reconstruction (100) of the failed disk data, the block corresponding to the error block does not allow the reconstruction of the corresponding failed disk block. To prevent the misuse of the two data blocks, a bad data table [BDT] (23) is constructed that lists the addresses of the block just read and the block to be reconstructed. Also a standard filler block (106) is written into the two bad blocks and a new parity block (108) is created. The addresses of all access requests to the memory array (200) are compared with the BDT (109) and, if not listed, the access proceeds (200). If an address is listed, an error signal (204) is returned. For a listed write request (203), the bad block address is deleted from the BDT (205), new data written (206) into the block and a new parity block computed and stored (207).

Patent CA-2245427-A1 (CA)
Inventor: OGINO AKIRA
IPC: H04N7/167
Filed: 1998-08-24
Abstract: When digital image signals inputted through an inputting terminal are recorded on a disc, a medium-related information (a serial number in an TOC) of the disc, read from the disc, with a medium related information reading section is spectrum-spread in an SS additional information generating section and then digital image signals S2 on which the spectrum-spread medium-related information is superimposed in an SS additional information superimposing section are recorded on the disc.  When the signals attempt to be reproduced, the reproduction can be performed in the case wherein the medium-related information superimposed on the image signals recorded on the disc is consistent with the medium-related information of the disc on which the image signals are recorded.  Thus, copying of the information signals can be limited to the copying for private use.

Patent CA-2247094-A1 (CA)
Inventor: PIETIK INEN MARKKU
IPC: G01N23/04
Filed: 1997-02-27
Abstract: Procedure for determining the properties of a log (5), in which procedure a moving log is radiographed by means of more than one X-radiation source (4) and the radiographic information is received by means of detectors (9) measuring X-radiation. According to the invention, the stemwood and knots of the log are calculated by a principle based on a knowledge of the geometry and density of stemwood and knots. After the measurement, the effect of stemwood in the radiographic projections is eliminated by filtering and the knot mass is projected from the radiographic projections to volumetric elements (6) in a system of cylindric coordinates and, from the value of each volumetric element, an evidence value representative of the presence of a knot in the element is derived. The evidence values of mutually associated elements are combined, thus producing an evidence value for the aggregate to permit the knots to be located.

Title: Arc fault detector with multiple channel sensing and circuit breaker incorporating
Inventor: MACKENZIE RAYMOND WARREN
IPC: G01R31/02
Filed: 1998-09-28
Abstract: Arcing faults are detected by a multi-channel arc fault detector in which each channel includes a bandpass filter having an assigned discrete passband which is non-overlapping with the passband of any of the other bandpass filters. Thus, the detector can discriminate an arcing fault which produces white noise and therefore generates an output from all of the bandpass filters simultaneously from a carrier signal which will only produce an output from one bandpass filter. The output of the individual bandpass filters can be ANDed, for example, by comparators with a common pull up resistor, or by analog multipliers. The output of the arcing fault detector can be used to trip a circuit breaker.

Patent CA-2255104-A1 (CA)
Title: Motor operator with burn-out protection
Inventor: PUHALLA CRAIG JOSEPH
IPC: H01H3/20
Filed: 1998-12-04
Abstract: A motor operator for a circuit breaker has a motor driven carriage which engages a circuit breaker handle and drives it between an on position and a reset position beyond off.  When the carriage drives the handle to the on position, an on limit switch is actuated to deenergize the motor.  A fastener releasably secures a bracket slidably mounted on the carriage to a fixed member when the carriage reaches the on position of the handle so that if the circuit breaker is not reset and rebounds toward a trip position, the bracket is extended and maintains actuation of the on limit switch.  Hence, the motor is not repeatedly energized and burned out in unsuccessful attempts to turn on the circuit breaker.  A similar arrangement prevents the motor from cycling when the off relay is latched.
