Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for phase offset adjustment in an electro-optical modulator. In one embodiment, the apparatus may include an electro-optical modulator having first and second arms, to modulate light passing through the arms according to an electrical data signal provided to the electro-optical modulator, to output an optical data signal that combines first and second light portions outputted by the first and second arms respectively; and a control module to convert the first and second light portions into first and second power signals indicative of respective phases of the first and second light portions, determine a balance between the first and second power signals, and adjust a phase of one of the first or second light portions, to achieve a bias point to provide the balanced optical data signal. Other embodiments may be described and/or claimed.

Abstract: An improved switch input arrangement for a system that remotely controls distributed electrical loads. The switch input arrangement is part of a transceiver decoder that receives commands from central controller for controlling the state of latching relays for controlling the power circuits of the loads. The improvements include: monitoring the state of contact closure inputs to the transceiver decoder, selectively enabling/disabling specific contact closures to control the masking of switch inputs, inclusion of an accumulated switch buffer to store the last actuation state of all relays, an answerback to insure that action occurs responsive to a switch input, a shifting threshold and multiplexing technique for more accurate reading of contact closure switch inputs, and the inclusion of a power-up reset message annunciated to the central controller to alert it that certain commands may have to be issued in order to reestablish the desired states of the transceiver.

Abstract: An improved relay actuating processor for a system that remotely control distributed electrical loads. The relay module is a part of a transceiver decoder that receives commands from a central controller for controlling the state of latching relays for controlling the power circuits of the loads.
