In a tactile sensation presentation panel according to the present disclosure, a tactile sensation presentation screen includes a tactile sensation electrode including a plurality of first electrodes and a plurality of second electrodes alternately disposed on a transparent insulation substrate at intervals. A first voltage signal having a first frequency is applied to the plurality of first electrodes located in at least a partial region of the transparent insulation substrate, and a second voltage signal having a second frequency different from the first frequency is applied to the plurality of second electrodes located in the at least partial region of the transparent insulation substrate. First electrostatic capacitance formed between the tactile sensation electrode and a pointer is calculated. An amplitude voltage and frequency of first and second voltage signals are adjusted based on the calculated first electrostatic capacitance.

When transmitting a digital video signal having, as a variant clock signal, a clock signal of a frequency which does not fall within a predetermined frequency range, a frequency multipliercarries out a frequency conversion of the frequency of the variant clock signal so as to generate a transmit side clock signal which falls within the predetermined frequency range, and a transmitting unit transmits, as a transmission digital video signal, the digital image data and control signal, as well as the transmit side clock signal, according to this transmit side clock signal. A receive side divides the frequency of the transmit side clock signal using a frequency dividerto obtain the variant clock signal after acquiring the digital image data and control signal from the transmit side digital video signal according to the transmit side clock signal.

The fixation of a coaxial cable between a GPS receiver and a receiver antenna mounted in a vehicle to an earthing conductor allows the elimination of influences due to noise and the improvement of reception even if the GPS antenna and the receiver antenna are mounted on the same mounting board due to reduction in the size of the device.

Receiver

A remaining fuel Z is calculated by subtracting a fuel injection amount J supplied to an engine from stored fuel F measured by a fuel meter A fuel economy Fm is calculated by dividing a running distance M of a vehicle by a fuel injection amount J. A cruising distance K is calculated by multiplying the remaining fuel Z and the fuel economy Fm.

Determination is made as to whether or not a self-diagnostic tester is connected with a K line . When the result of the determination indicates that the self-diagnostic tester is not connected with the K line , data indicating vehicle-operating conditions are obtained from an engine ECU and the like through a K line

A digital receiver has a receiving section for receiving a digital modulated signal, a digital demodulation section for judging a logical state of a detection output signal obtained by performing a digital detection operation for the digital modulated signal, for demodulating the digital modulated signal and for generating a data signal. The digital demodulation section has a binary conversion circuit for converting the data signal into a binary signal and a receiving quality detection device for detecting a receiving quality of the data signal based on a wave-form of the binary signal. The receiving quality detection device has a pulse generator for generating pulses having a time width between a positive pulse width of the wave-form of the binary signal based on the digital modulated signal and a time width between a third time width and a time width which is obtained by subtracting a negative pulse width of the wave-form of the binary signal from a second pulse width. The digital demodulation section has a wave-form shifter for shifting the wave-form of the binary signal of the in phase, a data judgement device for judging a state of the detection output signal based on a synchronous clock signal, and an exclusive OR device for performing a logical exclusive OR operation between the wave-form of a wave-form of output from the data judgement device and a wave-form of output from the wave-form shift means.
