An adjustable leg assembly includes a base leg which receives a pair of spaced, multiple section slides, each having one end coupled to a motor actuator attached to the underside of a work surface and an opposite end coupled to the base leg. Each of the laser portion and amplifier portion has a waveguide layer with the waveguide layers being in alignment. The latency circuit stores read information in accordance with at least one of the plurality of sampling signals, and generates a latency signal based on the transfer signal associated with the sampling signal used in storing the read information. A transition detection unit generates at least one transition detect signal responsive to the ID1, ID0, and Q samples. Thus, circuit elements having different sizes of currents to be handled are mounted on the same board.
