A delay-adjusted digital-unit interface comprises a first node, a second node, a third node, and an amplifier assembly. The first node is connected to a pull-up resistor and can be connected to the signal line of a transmission line connected to a first digital unit at a distal point. The second node is configured to be connected to a second reference electrical potential, a signal-return line of the transmission line, and a signal-return line of a second digital unit. The third node can be connected to a signal line of the second digital unit. The amplifier assembly is configured to be connected between the first node and the third node, to transform between high electrical potentials on the first node and lower electrical potentials on the third node, and to diversely delay low-to-high and high-to-low signal transitions transmitted by the second digital unit during communication with the first digital unit.

Delay-adjusted digital-unit interface

A sealed linear lighting fixture example comprises a heat sink, an electrical cable, two end caps, two compressive clips, a light-emitting element, an electrical assembly, two end blocks, four gaskets, a lens, and some fasteners. The heat sink and end blocks enclose the electrical assembly. The light-emitting element connects to the electrical assembly through a port in the enclosure wall. An end block acts as a strain relief for the electrical cable and facilitates a seal between the cable and an end cap. An end gasket facilitates a seal between an end cap and an end of the heat sink. Grooves in the heat sink and the end caps retain a lens gasket that seals the lens to the rest of the structure. The compressive clips press the lens against the lens gasket and include catches that engage ridges on the heat sink.
