Abstract: The present disclosure relates to a system and method of cancelling feedback in a vehicle communications system. The system and method may adjust a phase and a polarity of the microphone signal to produce an inverted microphone signal having a shifted phase. A speaker signal may be summed with the inverted microphone signal to cancel out at least a portion of a microphone signal component of the speaker signal.

Abstract: A programmable trim control system for marine applications preferably includes a controller, a control panel, a display device and a plurality of sensors. The controller receives input from the control panel and the plurality of sensors. The display device acts as a monitor for the controller. Each sensor monitors a single drive device, trim device or operational parameter. The controller further includes output ports connected to the drive devices and trim devices for controlling thereof. The trim control system preferably includes a manual mode, a diagnostic mode, a program mode and a preset mode. The positions or settings of the trim and drive devices are set in the program mode and recorded in the controller. Data stored in the controller will be accessed by the trim control system when in the preset mode.
