Abstract: The disclosure describes a method for detecting an arc in a direct-current (DC) circuit comprising a DC load, a DC source supplying the DC load, and a circuit arrangement arranged between the DC source and the DC load. A power flow P between an input and an output of the circuit arrangement is suppressed by means of a switching circuit through cyclical interruption such that the power flow P is enabled in an active time window with the first period Δt1 and the power flow P is suppressed in an inactive time window with the second period Δt2. Via detection of an input current Iin flowing at the input and/or an input voltage Uin applied to the input and comparison of values of the input current Iin and/or input voltage Uin detected in the inactive time window with a current threshold value ITH or a voltage threshold value UTH an arc presence criterion is signaled if the input current Iin detected in the inactive time window falls below the current threshold value ITH and/or the input voltage Uin detected in the inactive time window does not exceed the voltage threshold value UTH. The application also describes a circuit arrangement for detecting an arc and a photovoltaic (PV) inverter including such a circuit arrangement.

Abstract: An equipment inspection system receives data captured by a sensor of an autonomous vehicle (AV). The captured data describes a current state of equipment for servicing the AV. The equipment inspection system compares the captured data to a model describing an expected state of the equipment. The equipment inspection system determines, based on the comparison, that the equipment differs from the expected state. The equipment inspection system may transmit data describing the current state of the equipment to an equipment manager. The equipment manager may schedule maintenance for the equipment based on the current state of the equipment.

Abstract: An electrical connector for a safety restraint system of a motor vehicle comprises a housing, a pair of electrical terminals, a shunt and a connector position assurance (CPA) device. The housing includes a first end and a second end, the second end extending in a mating direction of the connector. Each of the electrical terminals traverses the housing from the first end to the second end. The shunt is adapted to short-circuit the pair of electrical terminals, and comprises two shunt arms each having a contact portion and a linking portion, and a shunt bridge linking the linking portions of the shunt arms. The CPA device is moveably arranged in the housing between an unlocked position and a locked position. In the locked position the CPA device lifts the shunt from a short-circuiting position across the terminals.
