Title: Pattern matching device
Inventor: TSURUTA SHICHIRO
IPC: G06K9/64
Filed: 1982-03-05
Granted: 1987-12-23
Abstract: The pattern matching device carries out pattern matching between two information compressed patterns applying a dynamic programming technique on calculating a similarity measure between the patterns. On carrying out matching of the two patterns a weighted similarity measure calculator (64) calculates a weighted similarity measure by multiplying and intervector similarity measure between one feature vector of each of the respective patterns by a weighting factor calculated by the use of a variable interval between each feature vector and the previous one. A recurrence formula is calculated by use of such weighted similarity measures instead of the intervector similarity measures. A predetermined value  delta may be used in reducing the number of signal bits used for the recurrence formula. Preferably, a sum for the recurrence formula is restricted by two preselected values. Most preferably, an additional similarity measure is used for the recurrence formula.

Abstract: The control uses the duty factor of a sequence of pulses to set the open/close times of the valve. The relative switch-on time is given by a specified equation involving constants and an input variable that in the case of a heat pump is the outside temp. or in the case of a fuel-fired heat source whose fan speed is being controlled, then the input variable is the voltage. The control has two amplifiers (14,15). The first amplifier's output is coupled to the comparator (18) whose output drives the device (27) that operates the expansion valve. The output of the second amplifier is integrated and passed to the comparator's second input.
