Abstract: In a multi-channel resistance-based gas sensor system, the multi-channel array includes gas sensor channels respectively connected to resistive type gas sensors. The pre-processing unit selects a current mode, a resistance mode, or an external resistance mode, analyzes a sensing value obtained from any one of the gas sensor channels based on the selected mode and outputs a voltage value corresponding thereto. The analog-to-digital converter (ADC) converts the voltage value to digital data. The control unit controls the pre-processing unit to execute one of the current mode for analyzing a sensing value smaller than or equal to a preset first resistance value, the external resistance mode for analyzing a sensing value greater than or equal to a preset second resistance value greater than the preset first resistance value and the resistance mode for analyzing a sensing value between the preset resistance first value and the preset second resistance value.

Abstract: There is provided a phase-domain detection apparatus for MIT application. The phase-domain detection apparatus includes a phase-locked loop unit configured to generate a plurality of reference clock signals having different phases and a phase-domain detection unit. The phase-domain detection unit is configured to receive the reference clock signals from the phase-locked loop unit, receive a response clock signal that is a phase-shifted reference clock signal of a reference clock signal inputted and passed through to a target object among the reference clock signals, and detect a phase difference between the reference clock signal inputted to the target object and the response clock signal.

Abstract: A composite monitoring apparatus includes a biosensor configured to sense a biometric signal of a driver in a motor vehicle, an air quality sensor configured to sense an air quality inside the motor vehicle, and a control unit. The control unit determines whether data on the air quality sensed by the air quality sensor exceeds an air quality reference value when data on the biometric signal sensed by the biosensor exceeds a biometric signal reference value. Further, the control unit generates an air quality warning alarm when the data on the air quality sensed by the air quality sensor exceeds the air quality reference value.

Abstract: A touch panel includes a first touch electrode disposed on a base substrate and a second touch electrode disposed on an insulating layer, which is disposed over the first touch electrode. The first touch electrode includes a first linear pattern disposed along a first direction and a first protrusion pattern extending from the first linear pattern. The second touch electrode includes a second linear pattern disposed along a second direction crossing the first direction and a second protrusion pattern extending from the second linear pattern. Wires connect the first touch electrode and the second touch electrode to a driving circuit. The second protrusion pattern partially overlaps the first protrusion pattern.
