An interlocking adapter in one aspect of the present disclosure includes a current path, an electric load, a switch, and a controller. The controller turns on and off the switch in synchronization with a change of an alternating-current voltage received from an electric outlet of an electric apparatus in response to reception of an interlocking command signal from a working machine so as to supply a load current from the electric outlet to the electric load. The controller turns on and off the switch at a specified ratio of a time every cycle of the alternating-current voltage.

An arrangement involving printed conductive traces includes at least a voltage source (V.sub.supply) and at least one target component, preferably a light-emitting component such as an LED. The arrangement is adapted to produce a current-controlled voltage (V.sub.OUT2, V.sub.out) originating from the voltage source, the current-controlled voltage being coupled to the at least one target component, wherein said voltage is dependent on the current (I.sub.R,LED, I.sub.LED) that is being passed through the target component and said voltage is adaptable to a varying resistance of the arrangement and its features.

Various electronics systems may benefit from appropriate limitation of short-to-ground current. For example, sensor systems may benefit from a voltage sensing mechanism to minimize short-to-ground current for low drop-out and bypass mode regulators. A system can include a first power transistor configured to operate in a low drop-out mode. The system can also include a short to ground sensor configured to control current to the first power transistor. The short to ground sensor can be configured to limit a maximum short-circuit current below a predefined load current capability.
