Abstract: The present invention relates to a piezoelectric cooling control apparatus and method, which set pulse parameters based on the temperature of the heating unit of a cooling target device, and thus control piezoelectric cooling. The piezoelectric cooling control apparatus includes a temperature sensing unit for sensing temperature of a heating unit of a cooling target device. A determination unit determines whether to activate piezoelectric cooling, based on the sensed temperature of the heating unit and a temperature setting range. A setting unit is configured to, if it is determined by the determination unit to activate piezoelectric cooling, set pulse parameters based on the temperature setting range and the temperature of the heating unit. A pulse control unit generates a PWM waveform based on the set pulse parameters and outputs the PWM waveform. A piezoelectric cooling unit performs piezoelectric cooling based on the PWM waveform.

Abstract: An apparatus and method for controlling the taillight of a vehicle are disclosed. The apparatus includes a visible light wireless communication data generation unit, a brightness control unit, a variable pulse position modulation (VPPM) signal generation unit, and a light source. The visible light wireless communication data generation unit generates information about the operation of a vehicle. The brightness control unit generates a brightness control value that is used to control the brightness of a light source installed at the tail of the vehicle. The variable pulse position modulation (VPPM) signal generation unit controls a pulse position and a pulse width within a unit pulse section of a pulse that controls the light source based on the information about the operation of the vehicle and the brightness control value.
