Title: Electronic tester for assessing battery/cell capacity
Inventor: CHAMPLIN KEITH S
IPC: G01R31/36
Filed: 1991-08-27
Granted: 2000-06-06
Abstract: A self-contained electronic device (4, 6, 8) instantaneously assess the stored energy capacity of single, two-volt; lead-acid cells (26); or of batteries comprised of such cells (26). The testing device is electrically connected to the terminals of a cell or battery (26) and measures its dynamic conductance with a small; time-varying signal (36). An internal conductance standard (24) permits initial calibration of the device to assure accuracy of the cell/battery measurements. Means (56; 58, 60, 62, 64, 66, 68) are provided for entering a "reference conductance", defined to be the dynamic conductance of an identically rated and constructed cell or battery having 100 % energy capacity. The device displays (50, 72) either the test cell/battery's measured conductance in Siemens (mhos), or its "percent capacity"  determined by appropriately scaling its measured conductance in accordance with "reference conductable". When determining "percent capacity", an LED (72) lights if the result is less than a preset threshold value (70).

Patent CA-2132756-C (CA)
Inventor: SIMARD PATRICE YVON
IPC: G06G7/60
Filed: 1994-09-23
Granted: 1999-05-18
Abstract: Nodal outputs are discretized to values of S2n where n is an integer and S is equal to +1 or -1. During forward propagation, this offers the advantage offorming a product of a nodal output and a weight using a simple shift operation rather than a multiply operation. Replacing multiply operations with shift operations through out a neural network improves response times and permits building largernetworks that have broader applicability. Training is also improved by increasing the efficiency of backward propagation. The multiplications involved in backwardpropagation are reduced to shift operations by discretizing the errors associated with each node so that they are represented as S2n where n is an integer and S is equal to +1 or -1.

Title: Identification card verification system and method
Inventor: KRISTOL DAVID MORRIS
IPC: G06K19/10
Filed: 1996-02-27
Granted: 2000-04-04
Abstract: A self-verifying identification card having an image area which may contain a portrait, a finger print, a retinal image, or all of these together with an image signature which is derived from scanned intensity measurements taken from the image area.  In the verification process, the image is scanned and aligned with respect to reference points corresponding to the original printing process which created the card, and intensity values, their averages, or any other function are compared to information provided by the image signature.  Mathematical transformations, such as a one-way hash, an encryption, a compression algorithm, or a truth table may be used to encode the image signature. Alignment markers aid in scanning the image and the image signature.  The use of average values aids in reducing noise and the use of comparison functions makes the process less sensitive to variations among scanners.  The verification may be done at the point of a transaction, for a standalone system, or may be referred to a centralized data base in a networked system for further inquiry.  In a networked system the image signature may be stored in the database.
