Title: A method for predicting an abnormal level of clotting proteins
Inventor: FISCHER TIMOTHY J
IPC: G06F19/00
Filed: 1998-12-30
Abstract: A method is disclosed for predicting the presence of an abnormal level of one or more proteins in the clotting cascade from at least one time-dependent measurement profile. At least one time-dependent measurement on an unknown sample (103) is performed and a respective property of the sample is measured over time so as to derive a time-dependent measurement profile (101).  A set of a plurality of predictor variables (110) are defined which sufficiently define the data of the time-dependent measurement profile (101). A model (113) is then derived that represents the relationship between the abnormality and the set of predictor variables (110). Subsequently, the model (113) is utilized to predict which protein or proteins in the clotting cascade are at an abnormal level, with the prediction (120) being a better prediction than clot time alone.

Title: Method and system for describing predicates in disjuncts in procedures for test coverage estimation
Inventor: SUMAR HARRY M
IPC: G06F11/36
Filed: 2000-09-15
Abstract: To estimate test coverage of procedure testing with functional specification of a procedure, predicates in functional branches in the procedure are described as logic expressions. The logic expressions of predicates are added to logic expressions of pre-condition of the procedure. Based on the logic expressions, functions of the functional specification of the procedure are generated and coverage during the procedure testing is estimated. In an embodiment, Disjunct Normal Form (DNF) is generated using short logic which omits calculation of an operand when another operand defines the result of the calculation. In another embodiment, Full Disjunct Normal Form (FDNF) is generated using three-sign logic.

Title: Diagonal supporting conductors for loop antennas
Inventor: PODGER JAMES STANLEY
IPC: H01Q1/12
Filed: 2001-01-12
Abstract: Supporting conductors for loop antennas that are positioned within the principal H plane of the loop antennas and positioned diagonally with respect to the plane of the loops. Such diagonal supporting conductors do not interfere with the electrical operation of the loop antennas, and they can be stronger than the traditional long supporting insulators that are often broken by bad weather. These conductors may also reduce the movement of the loop antennas in the wind and may have less weight and cost than the combination of a supporting conductor placed directly across the loop plus a supporting boom.

Patent CA-2337429-A1 (CA)
Inventor: KUMAR SANKARAN
IPC: A61B6/12
Filed: 2001-02-16
Abstract: A probe instrument using room-temperature sensor(s) that can measure magnetic susceptibilities variations. The instrument includes room temperature magnetic sensors, and detects the sample, that is the tissue response to an applied field coil.  The sensors that can be used include magnetoresistive, fluxgate and magnetoinductive sensors. The applied field coil dimensions are chosen so that the applied field is optimized for maximum response from the item of interest while minimizing the effects due to the overlying tissue and at the same time not unduly increasing the sensitivity of the instrument to adjacent organs. To minimize noise introduced in the sensor due to fluctuations in the applied field, the applied field is canceled at the position of the sensor. To overcome variations in the sensor output due to fluctuations in the applied field, change in the ambient temperature and mechanical relaxation of the instrument, the detector assembly is oscillated while the examined patient remains stationary.
