Abstract: A fixed-type solar generator with minimally controlled reflector includes: solar collector panel facing culmination of sun, first and second reflectors rotatably provided on east and west sides of the solar collector panel, respectively, sensor module and control module. The sensor module includes a first sensor for detecting greater light amount from sun while in a first section from sunrise to culmination than while in a second section from culmination to sunset, and a second sensor for detecting greater light amount from the sun while in the second section from culmination to sunset than while in the first section from sunrise to culmination. The control module controls a rotation angle of at least one of the first and second reflectors based on a first light intensity value detected by first sensor and a second light intensity value detected by second sensor.

Abstract: An apparatus for automatically controlling a crossing gate being installed at an entrance/exit way of a vehicle and controlling entrance/exit of the vehicle, including: a password setting unit for setting a combined row of input numbers or characters as a password; a signal sensing unit for sensing a change in an amount of light of light signal patterns of the vehicle; and a controller including a first signal converter that analyzes the sensed change in the amount of light of light signal patterns of the vehicle and that converts the analyzed light signal patterns into a Morse code, a second signal converter that converts the converted Morse code into a combined row of numbers or characters, and a driving controller that controls opening/closing of the crossing gate depending on whether the converted combined row of numbers or characters is the same as the password set by the password setting unit.
