摘要： In an apparatus for detecting abnormal variation of wheels of a vehicle, a plurality of rotation sensors detect variations in rotation speeds of a plurality of wheels during running of the vehicle. Detection signals produced from the plurality of rotation sensors are converted into arithmetic operation signals by means of a signal converter. An arithmetic operation processor is responsive to the arithmetic operation signals from the signal converter to compute rates of variations in the rotation speeds. The arithmetic operation processor also compares the computed rates of variations with each other to decide whether wheels exist which have a rate of variation abnormally deviating from rates of variations of the other wheels. An alarm unit is responsive to decision signals from the arithmetic operation processor to alert abnormality of the wheels having the abnormally deviating variation rate.

摘要： The invention provides an apparatus for controlling the rotation of a rotating body in a recording and/or reproducing apparatus. First, the apparatus detects the rotational speed of the rotating body, as it is driven by a DC motor. Detection is in terms of a frequency which is n times the speed, in which n>> 1. Second, there is a detection of the rotational phase of the rotating body. The DC motor is driven to rotate in accordance with a controlling signal obtained by using first and second output error signals responsive to the first and second detections. The DC motor is driven by means for superimposing an AC signal generated with a constant period and the first and second output error signals. The superimposed signals are sliced at a predetermined level to perform "ON" - "OFF" operations and a smooth output to control the driving rotation of the DC motor.

摘要： A digital alarm that produces a signal when a function that is being monitored falls below a preset alarm point. The monitored function may be the speed of a shaft. Input pulses representing the function to be monitored are fed into the device and the period of the input pulses are compared with the interval of a signal generated by a monostable multivibrator within the device. If the input signal period is greater than the multivibrator interval, the alarm sounds, but if the input signal period is less than the multivibrator interval the alarm is off. When the alarm is driven either off or on, it is held there until the monitored function changes to the complement condition.

摘要： An improved predetermined speed detector for use in a digital tachometer where signal pulses proportional in repetition rate to engine speed or RPM are available. The signal pulses are used to trigger a monostable multivibrator such that the duty cycle of the monostable output is a function of the signal pulse repetition rate (hence RPM) and the characteristic period of the monostable circuit. The time coincidence of the input signal pulses and the monostable output is then detected to obtain an indication of a predetermined duty cycle and hence engine RPM for any given characteristic monostable time period. Thus by merely detecting the time coincidence of these two signals with a latched AND gate (such as an RS flip-flop or equivalent) engine shift indicators, excessive speed indicators (i.e., horns, flashing lights, etc.) and/or engine disabling devices may be conveniently actuated.

摘要： A shaft overspeed detector has a shaft-mounted strip which periodically interrupts a light beam falling on a photosensitive cell as the shaft rotates. An electrical circuit provides a timebased pulse for each interruption and if a second interruption occurs before the time-based pulse has risen to a cutoff level, a speed controller is activated.

摘要： A counter system including a magnetically actuatable switch housed in a protective case. The case is secured to a frame supporting a rotatable mixing drum. A magnetic actuator is resiliently mounted on the drum and is moved past and close to the switch at each drum revolution. The switch is connected through an electrical circuit to a counter so that total revolutions of the drum are measured. A second counter system measures both total and mixing speed revolutions of the drum. In this second system one counter is actuable only if the drum is turning at a preselected speed. Two switches are used and they are connected to an electrical circuit which provides a signal to the mixing counter only if the drum is turning at mixing speed.

摘要： Exemplary embodiments are provided of telematics devices and exemplary corresponding methods. In an exemplary embodiment, a telematics device generally includes a controller and a wireless communication module for transmitting data to a remote station. The controller is configured to periodically obtain the speed of a vehicle, determine when the speed of the vehicle has exceeded a first speed threshold, store the monitored speed as a max speed value, and compare each successive monitoring interval speed to a previous monitoring interval speed. When the successive monitoring interval speed is greater than the max speed value, the max speed value is updated. A speeding event occurs when each successive monitoring interval speed is above the first speed threshold for a speed duration, and/or when any successive monitoring interval speed exceeds a second speed threshold.

摘要： An antiskid control system for a vehicle in which acceleration and deceleration control signals are generated by a control circuit in accordance with the rotational speed of a wheel monitored by a sensor device that produces a pulse train whose frequency varies with wheel speed. A digital counter operates for the duration of each pulse cycle of the sensor signal whereby the pulse count obtained represents a cycle duration of the sensor signal. Within the control circuit to which the sensor signal is supplied, a control unit transfers the pulse count after each cycle to a first shift register as a measure of the cycle duration. The first shift register outputs the pulse count of the measured cycle duration to a comparator to which there is also connected a pulse count of a reference cycle duration supplied by a second shift register to which the pulse count of a previous measured cycle duration has been supplied by the first shift register to form the reference cycle duration. The reference cycle duration and measured cycle durations are compared to obtain a difference signal which is subsequently compared to an admissible difference signal to provide the acceleration and deceleration control signals when the difference exceeds a preselected amount. The admissible difference is formed as a fraction of the reference cycle duration by selecting an output of the second shift register corresponding to a preselected stage thereof.
