    摘要: A ring oscillator including a plurality of flip-flops is provided. The flip-flops are connected in a ring. The flip-flops are configured to start to oscillate according to a start signal to generate an output signal, and stop oscillating according to a stop signal to stop generating the output signal. When the stop signal changes from a first level to a second level, the output signal becomes floating. In addition, a time measuring circuit including the foregoing ring oscillator is also provided.

    摘要: To synchronize, in a system in which a plurality of devices perform measurement, measurement timings with each other with a simple configuration. A sensing system includes a plurality of sensor devices. The sensor devices each include a trigger sensor and a target sensor. In the sensor device, the trigger sensor measures a signal value of a trigger signal. Also, in the sensor device, the target sensor starts to measure a physical quantity when the signal value measured by the trigger sensor satisfies a predetermined condition.

    摘要: The present invention makes it possible to measure a precision event time in such a way to make a reference data in accordance with a standard time reference frequency signal and to make a measurement data by using an apparatus with the same structure as a reference data with respect to a signal to be measured and to compare the measurement data with a reference data, whereby temperature effects can be minimized by making the time changes due to temperature changes occurring between two apparatuses happen equally, by providing the same structure and parts to a reference signal circuit apparatus for an event time measurement and a signal circuit apparatus to be measured, and the zero point adjustment is performed during the real time operation, so the system is not needed to stop.

    摘要: An electric counter circuit (30, 40, 80) comprises a clock generator (1, 54, 111, 120, 130) for generating a plurality of clock signals (21-24, 121-125, 131-134) and a sampling device (32, 81) for sampling the clock signals (21-24, 121-125, 131-134) at a first moment in time when a first characteristic signal section (LE) of a digital signal (DS) appears. Furthermore, the circuit (30, 40, 80) comprises a calculation device (33) for calculating the time between the first moment and a second moment which is later than the first moment. This calculation is based on the clock signals (21-24, 121-125, 131-134) at the first moment and based on the clock signals (21-24, 121-125, 131-134) at the second moment. The clock signals (21-24, 121-125, 131-134) each have the same cycle duration (T) and are phase-shifted with respect to each other.

    摘要: Random number generators are used for entertainment in gambling, lotteries and video gaming devices. True Random Number Generators, as are now currently defined, must be actuated by a physical noise source, typically based on the uncertainty of the phase differences of a stable and an unstable autonomous oscillator. In this invention an autonomous random frequency modulated oscillator driven by a self contained pseudo-random number generator outputs three loosely correlated random binary streams. Included in the invention is a hardware method for proving wandering phase differences and also the existence of a colored random distribution of concatenated nibbles.
