Title: Picture change detection method
Inventor: NISHIOKA ATSUSHI
IPC: H04N7/18
Filed: 1992-09-10
Abstract: PURPOSE:To reduce a required storage quantity by compressing data while accumulating respectively in X and Y directions. CONSTITUTION:A picture in the usual state in a prescribed monitor area is inputted by an ITV camera 1 and a pre-processing circuit 3 implements pre- processing such as smoothing to eliminate noise. Then a projection distribution arithmetic operation 4 accumulates the processed picture in X and Y directions respectively to obtain the projection distribution in the X and Y directions. The result of the distribution averaged in the X and Y directions respectively is used for a reference projection distribution of the monitor area and it is stored in a reference projection distribution memory 5. A comparator discrimination circuit 8 compares a prescribed threshold value set for each object with a projection distribution in each direction and when the setting value is exceeded, it is discriminated that there is any change in the monitor area and an alarm is raised. Thus, data for each picture element are not entirely stored but the data are compressed through accumulation in the X and Y directions by one line each thereby reducing required storage data quantity.

Title: Power semiconductor module
Inventor: KAJIWARA TAMAO
IPC: H02M7/48
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To easily change the operating current of an overcurrent protective circuit incorporated in a power semiconductor module. SOLUTION: A power converting part 30b converts a DC current inputted via terminals t2, t3 into a three-phase AC, in accordance with a control with a control device 30a and outputs it from terminals t4, t5, t6. The control device 30a controls the power converting part 30b, in accordance with for example, pulse width modulation(PWM) signals inputted via a terminal t1. An overcurrent protecting section 30d detects a voltage across the terminals of a current detecting resistor 30c provided at a given position on the power converting part 30b and transmits a signal to the control device 30a, if the current in the power converting section 30b exceeds a certain level. As a result, for controlling the power converting part 30b, the control device 30a prevents an overcurrent from flowing in the power converting part 30b.  Connected to both terminals of the current detecting resistor 30c, terminals t7, t8 enable taking out a voltage which is produced across the terminals of the resistors to an external unit.
