Abstract: An information display system 10 comprises a display device 21, a seat box 30, a LAN cable 41, and a GMSL 42. The display device 21 has a display 21a that displays various kinds of information, and a USB connection part 21b that inputs and outputs data. The seat box 30 has a housing different from that of the display device 21, and processes video signals related to video displayed on the display 21a. The LAN cable 41 connects the display device 21 and the seat box 30, and uses IP protocol to perform communication between the display device 21 and the seat box 30. The GMSL 42 connects the display device 21 and the seat box 30, and transmits a signal from the seat box 30 to the display device 21 using a GMSL 42 that is different from that of the LAN cable 41.

Abstract: A physical quantity sensing device includes a bridge circuit that has first and second input points, to which an AC voltage is applied, and first and second output points connected to a differential amplifier. The bridge circuit includes a first bridge arm for electrically connecting the first input point to the first output point, a second bridge arm for electrically connecting the first output point to the second input point, a third bridge arm for electrically connecting the first input point to the second output point and a fourth bridge arm for electrically connecting the second output point to the second input point. The first bridge arm includes a first sensor element, of which the impedance changes with a physical quantity to be measured, and the second bridge arm includes a second sensor element, of which the impedance also changes with the physical quantity to be measured. The total impedance of the first and second bridge arms is smaller than that of the third and fourth bridge arms.

Abstract: A gas detection device includes a gas sensing portion, a heater, and an insulating layer provided between the gas sensing portion and the heater. The gas detection device further includes a control section and a portion of an engine control device for controlling operations of the gas sensing portion and the heater, the control section ensuring that timing of changing a current supplied to the heater is synchronized with a detection operation by the gas sensing portion. The gas detection device prevents detection errors of a gas sensor even when noise associated with temperature control of a heater occurs.

Abstract: A physical quantity sensing device includes an AC voltage generator for generating an AC voltage and a bridge circuit that has first and second input points, to which the AC voltage is applied, and first and second output points connected to a differential amplifier. The bridge circuit includes first and second sensor elements, the impedance of which change with a physical quantity to be measured. The first and second sensor elements have a positive temperature characteristic in which sensitivity increases as temperature rises. The AC voltage generator includes an amplitude limiter which has a negative temperature characteristic that decreases the amplitude of the AC voltage with a rise in temperature, thereby compensating for temperature dependence of a differential voltage produced between the first and second output points.
