An electronic fuse circuit includes an electronic switch with a load current path coupled between an output node and a supply node and that connects or disconnects the output node and the supply node in accordance with a drive signal. The circuit includes a control circuit to generate the drive signal based on an input signal. A monitoring circuit is included in the control circuit to receive a current sense signal representing the load current passing through the load current path and to determine a first protection signal based on the current sense signal and a wire parameter. The first protection signal is indicative of whether to disconnect the output node from supply node. The control circuit changes from normal mode to idle mode when the load current is below a given current threshold and another criterion is fulfilled.

A vehicle driving system that controls switching between automatic driving by a vehicle and manual driving by a driver of the vehicle includes a temperature sensor configured to monitor a temperature of an automatic driving ECU which controls the automatic driving; and a microcontroller configured to: (i) set a threshold temperature based on an estimated gradient of increase in the temperature of the automatic driving ECU, the estimated gradient of increase being estimated based on a drive state of an equipment installed on the vehicle, and (ii) in a case where the temperature of the automatic driving ECU that is sensed by the temperature sensor becomes equal to or greater than the threshold temperature, perform an operation for prompting the driver to switch to the manual driving during the automatic driving.

A sensing device and a determining system for determining the location, the movement or even other properties of one or more objects. A sensing device is attached to one object, and contains at least a trigger module and a sound module. The trigger module is configured to generate a sensing signal, and the sound module is configured to generate and transmit a wide-frequency sound signal correspondingly. The determining system contains at least one such sensing device and an analyzing device configured to receive and analyze the wide-frequency sound signal. Therefore, one or more properties of the object(s) may be monitored. In general, the trigger module is configured to couple electrically one or more crystal oscillators with the sound module, so that the oscillation signal generated thereby may be controllably converted into the wide-frequency sound signal.

A mitigation control system is arranged in an environment containing an energetic material and includes an abnormal temperature sensor for detecting an abnormal temperature of the environment, a power source that is mechanically actuated by the abnormal temperature sensor when the abnormal temperature exceeds a predetermined abnormal temperature threshold, a mitigation controller that is actuated by the power source, and a plurality of local temperature sensors that are communicatively coupled to the mitigation controller and are arranged for detecting critical temperatures in specific regions of the environment. The mitigation controller executes a mitigation action when one of the critical temperatures exceeds a predetermined critical temperature threshold for the corresponding specific region.

An improved method and system for controlling the powering-on of an electronic device when initially the internal temperature is below a safe threshold. The method and system can preheat the electronic device until it is at a safe temperature in which to safely power-on the electronic device. Alternatively or in addition, the method and system can alert a user if the temperature is below a threshold and proceed to power-on when the temperature is above the threshold.

Various smart doorbell arrangements are presented. Based on a measured temperature of the smart doorbell, operation of the smart doorbell device may be altered such that more heat or less heat is generated without affecting user-facing features. Based on another measured temperature, operation of the smart doorbell may be altered such that a chime that is electrically coupled to the smart doorbell device is not sounded in response to a doorbell actuation, but that a notification of the doorbell actuation is wirelessly transmitted by the smart doorbell device.

A safety circuit, in the form of a switch box, for coupling with a catheter, detects DC leakage or emission from an amplifier circuit of the catheter, and switches a switch to immediately terminates (cuts-off) power to the amplifier circuit. This immediate power termination instantaneously stops DC leakage, which if left unchecked or otherwise undetected, may reach the heart, and disrupt its electrical activity and cause other damage.
