Abstract: PURPOSE: A segment display combined with a driving unit is provided to display numbers or characters using the minimum power in case the segment is changed. CONSTITUTION: A driving unit(20) is combined in the segment(30) for the display of the number or the character. The key signal for the operation of the driving unit is inputted to the input unit(10). An optical sensor(50) recognizes the intensity of the external light. The optical sensor changes the light to electric signal. The brightness of the lighting unit(40) is controlled by the optical sensor. The lighting unit lights the front side of the segment. A controller(60) controls the element. A segment display is connected in the computer terminal in parallel or serial data transmission mode.

Abstract: A PWM switching method and a PWM switching system for controlling a BLDC(Blushless DC) motor are provided to control a voltage applied to a motor by controlling a state of a switching element in a PWM off section when driving the motor. A PWM switching system includes a three phase BLCD motor(100), a PWM inverter(220), a controller(240), a position sensor(250), and a speed sensor(260). The PWM inverter includes six switching elements. The controller controls the on/off of four switching elements according to a current direction, a voltage direction, and PWM on/off of the PWM inverter. The current direction and the voltage direction are changed according to the position of a rotor of the BLDC motor. A position sensor detects the position of the rotor inside the BLDC electric motor. A speed sensor detects the speed of the BLDC electric motor.

Abstract: A feeding device for fish is provided to enable a user to change the kinds and the amount of feeds of fish, and to improve joy of rearing fish by letting a user recognize feeding time by outputting a sound. A feeding device for fish includes a feeding plate(210), a control box(230) and a feeding brush(220). Feeding holes(212) are formed along a circular track(211) on the feeding plate. A feeding position(213) is formed on one side of the feeding hole. The control box comprises a rotary motor and a control board. The rotary motor is shaft-coupled to the feeding plate to rotate the feeding plate. The feeding brush is supported by a support(221) fixed on the upper part of a body(231) of the control box and pushes the bait placed on the feeding position into the feeding hole.
