Filed: 1995-10-24
Abstract: Electromagnetic emissions from a printed circuit board are monitored by energizing the board while it is located adjacent to an array of electromagnetic measuring probes. The probes are successively addressed at a receiver. A memory map of the electromagnetic emission as a function of board position is generated and is displayed together with the circuit board layout so that regions of high emission level can be identified in the circuit. The probe array is imprinted into a circuit board. Each probe of the array is a pair of curved conductors, electrically connected serially at their cusps, whose concavities share a common orientation.
Patent CA-2163017-A1 (CA)
Title: Speech recognition method using a two-pass search
Inventor: GUPTA VISHWA NATH
IPC: G10L15/08
Filed: 1994-05-18
Abstract: A speech recognition method uses a two-pass search to match an unknown utterance to a vocabulary word. Words in the vocabulary are represented by concatenated allophone models and the vocabulary is represented as a network. On the first pass of the search, a one-state duration constrained model is used to search the vocabulary network. The one-state model has as its transition probability the maximum observed transitional probability (model distance) of the unknown utterance for the corresponding allophone model. Words having top scores are chosen from the first pass search, and rescored using a full Viterbi trellis with the complete allophone models and model distances. The rescores are sorted to provide a few top choices. Using a second set of speech parameters these few top choices are again rescored. Comparison of the scores using each set of speech parameters determines a recognition choice. Post processing is also possible to further enhance recognition accuracy. Test results indicate that the two pass search provides approximately the same recognition accuracy as a full Viterbi search of the vocabulary network.

Title: Multiple overload protection for electronic scales
Inventor: FREEMAN GERALD C
IPC: G01G23/00
Filed: 1995-12-20
Abstract: An electronic scale is disclosed which has multiple overload protection features for protecting the load cell and a weight distribution plate from excessive strain due to vertical overload on the scale or from twisting resulting from an article being placed thereon which exceeds the load capacity of the scale, or from excessive forces due to mishandling of the scale. A first overload protection is in the form of a boss molded into the base of the scale on which the free end of the load cell abuts if an excessive load is placed on the platter of the scale. A second overload protection is in the form of a peripheral depending flange on the platter which abuts a peripheral portion of the a top cover to prevent excessive strain on the load cell and a weight distribution plate from excessive loading or mishandling of the scale. A third overload protection is in a plurality of ribs which are molded into the base and which extend upwardly adjacent the undersurface of the four corners of the weight distribution plate so that the weight distribution plate abuts these ribs in the event that an excessive load is placed on the platter in an off center manner. The weight distribution plate is also provided with means for causing the weight of an article placed on the platter in an off center manner to be transferred to the point where the weight distribution plate is attached to the free end of the load cell so that an accurate weight is measured by the scale regardless of the placement of an article on the platter.
