Abstract: A vehicle air conditioner is controlled to a target control value that controls a swash-plate control value of a swash-plate variable capacity compressor. The variable control is based on temperature deviation between target evaporator temperature and actual evaporator temperature, to control compressor discharge capacity. A target evaporator temperature is set. Deviation between the target evaporator temperature and actual evaporator temperature is calculated. Control coefficients are variably set according to the magnitude of the temperature deviation. A target control value of a pressure control valve of the swash-plate variable capacity compressor is calculated using the control coefficients. The pressure control valve is controlled by the target control value.

Abstract: A high speed passband phase modulation apparatus and method are provided. In the phase modulation apparatus, an RF phase shifter modulates a phase of a local signal that is generated in a VCO according to a digital input. The RF phase shifter is controlled by a phase-controlled loop so that a baseband phase shifter is phased locked to a modulation reference signal from the local signal and a reference clock signal according to the digital input. The phase-controlled loop phase-locks using the modulation reference signal so that the phase-modulated signal generated in the RF phase shifter has a phase value according to the digital input.

Abstract: Disclosed is a method and system for detecting wired network errors in a mobile communication terminal, which performs a selective checksum operation for received data in a UDP (User Datagram Protocol) layer to improve the processing speed of the mobile communication terminal. In the system, it is determined whether to perform the checksum operation in the UDP layer by a UDP checksum setup value that is changed to a first setup value when an IP (Internet Protocol) header checksum error occurs in an IP layer. In this case, the UDP checksum setup value is changed to a second setup value when the UDP checksum operation is performed.
