摘要:
The invention relates to a method, a control arrangement, and a control device for controlling a rear lamp in a vehicle. The rear lamp is operated in an emergency signal mode when it is determined that an emergency signal event has occurred and based on one or more first initiation pulses associated with the emergency signal event transmitted to the control device from the control arrangement, wherein a duration of each of the one or more first initiation pulses is shorter than a duration of an emergency feed pulse. The invention also relates to a rear lamp, a vehicle, a computer program, and a computer-readable medium.

A delay selector includes a first multiplexer, a first inverter, a second multiplexer, and a second inverter. The first multiplexer has a first input coupled to an input of the delay selector. The first inverter is coupled between the input of the delay selector and a second input of the first multiplexer. The second multiplexer has a first input coupled to an output of the first multiplexer. The second inverter is coupled between the output of the first multiplexer and a second input of the second multiplexer.

A monitoring system for monitoring delay of critical path timing margins can include a plurality of adaptive monitoring circuits, where each adaptive monitoring circuit is coupled to a corresponding one of a plurality of paths in a circuit. Each adaptive monitoring circuit can include a first delay element designed to cause a mean timing margin of the plurality of N paths in the circuit to be within one minimum mean unit delay; a second delay element coupled to the first delay element and designed to add a mean delay of k* σmax; a set-up capture element capturing an output of the second delay element; and a set-up warning comparison element that outputs a set-up warning signal when the output of the set-up capture element and a shadow capture element or a capture element of the corresponding one of the plurality of paths do not satisfy an expected condition.
