Examples herein relate to an apparatus. In some examples, an apparatus may include a circuit to direct a power signal to at least one electrical component. The circuit may include a protection device to regulate power to the electrical component, detection circuitry to detect when the protection device has failed, and an alert handling logic to receive a signal from the detection circuitry that the protection device has failed.

A retention member monitoring system for a slat-flap control lever assembly including a control lever movable over a range of discrete angular positions. Also included is a retention member engageable with the control lever to retain the control lever in each of the discrete angular positions. Further included is at least one electric device in communication with the retention member to determine the structural integrity of the retention member.

A method and system for monitoring fuses in a vehicle are provided. The method includes receiving data from a fuse monitor coupled to one or more fuses. Each fuse associated with one or more electronic devices of the vehicle. The method also includes analyzing the data to determine whether a faulty fuse is detected and outputting an alert to a display of the vehicle in response to detecting a faulty fuse. The alert includes at least one of a fuse location, a fuse type, or fuse replacement information and activates a fuse application of the display of the vehicle to cause the alert to output on the display.

A surge protection device for an LED lighting system provides a failure detection circuit which shuts off an indicator lamp when upon failure of surge protection components. Surge suppression circuits are coupled between respective first and second, and second and third lines for receiving an AC mains input. The surge suppression circuits include a thermal cutoff device and a clamping device, with a fault detection circuit coupled between each respective series circuit. The fault detection circuit activates an indicator lamp when the surge protection device is in a normal operation mode. The fault detection circuit shuts off the indicator lamp when the surge protection device is in a short circuit fault mode, corresponding to failure of at least one component from a surge suppression circuit. Detection of an unlit indicator lamp may serve as a warning to an operator that the associated surge protection device should be replaced.

An electronic device includes a substrate, an electronic component disposed over the substrate and an electrical testing component disposed over the substrate. The electronic component includes a bottom plate over the substrate, and a top plate over the bottom plate. The electrical testing component includes a first anti-fuse structure and a second anti-fuse structure, wherein the first anti-fuse structure and the second anti-fuse structure are electrically connected to the bottom plate.

A method for detection of a fuse failure of a protective fuse used to protect an associated load against overcurrent and/or against overload includes the steps of: measuring electrical current flowing through the protective fuse in a current path to the load by means of a current sensor element; determining one or more failure indicators adapted to indicate a possible failure of the protected fuse on the basis of the measured electrical current; and detecting automatically a failure of the protective fuse if the determined at least one failure indicator indicates a possible failure of the protective fuse and if the electrical current stopped to flow through the protective fuse or is below a predefined current threshold value.

An adjustment method for the chip output characteristics can include the following steps. When adjusting the output characteristics of the chip to be tested, first it is determined whether the output characteristics of the chip to be tested have been adjusted according to the state of each E-fuse. When determining that the output characteristics of the chip to be tested have not been adjusted, the target adjustment solution corresponding to the chip is determined among a plurality of adjustment solutions in a targeted manner according to the output performance of the chip to be tested. The E-fuse in the chip to be tested is subjected to blowing treatment according to the target adjustment solution, so as to adjust the output characteristics of the chip to be tested.

A method may include operating a switching circuit in an on state and an off state to actuate a flow of electrical power through a load when switched to the on state; monitoring an electrical property associated with the switching circuit; receiving an enable signal from a processor to power the load; providing a drive signal to the switching circuit to switch to the on state and power the load; determining if an electrical anomaly is present based on the monitored electrical properties; causing the switching circuit to switch to the off state if an electrical anomaly is detected; providing a fault signal to the processor; determining while the switching circuit is off, if the electrical anomaly has been corrected; and after the anomaly has been corrected, causing the switching circuit to switch to the on state.
