摘要: Systems and methods for calibrating a conducted electrical weapon (“CEW”) to provide a predetermined amount of current for each pulse of the stimulus signal. Providing the predetermined amount of current, close thereto, increases the effectiveness of the stimulus signal in impeding locomotion of a human or animal target. The calibration process enables a CEW to calibrate the amount of charge in a pulse of the stimulus signal in the environmental conditions where the tester operates and also in the field where the environmental conditions may be different from the environmental conditions during calibration.

摘要: A measurement device includes a sensor unit capable of measuring a state of a measurement target, and a control unit configured to control the sensor unit. The sensor unit includes a measurement unit capable of measuring a voltage corresponding to the state of the measurement target, a first voltage comparison unit configured to determine whether or not the measured voltage is changed beyond a lower limit value of a predetermined voltage change, and a second voltage comparison unit configured to determine whether or not the voltage change is changed beyond an upper limit value of the voltage change. The control unit stops power supply to the sensor unit in a case in which it is determined in the first and second voltage comparison units that the measured voltage is not changed beyond the voltage change.

摘要: A device such as a laser diode is provided with a monitoring arrangement. The monitoring arrangement has voltage to current convertors arranged to provide respectively currents which are proportional to the respective voltages on an anode and on a cathode of the laser diode. The monitoring arrangement provides a first output signal when the laser diode is on too long. That output signal is used to cause the laser diode to be switched off.

摘要: In an example embodiment, a universal serial bus (USB) Type-C controller comprises a current detector circuit configured to provide over-current protection on a voltage bus (VBUS) line. The current detector circuit comprises a current sense amplifier, a reference voltage generator, and a comparator coupled to the current sense amplifier and to the reference voltage generator. The current sense amplifier is configured to receive a pair of input voltages from the VBUS line and to output an indicator signal responsive to an input voltage difference between the pair of input voltages. The reference voltage generator is configured to generate a reference voltage in response to a voltage selector signal. The comparator is configured to output an interrupt signal responsive to the indicator signal exceeding the reference voltage.
