    Abstract: A hydraulic control circuit for a hydraulic on-vehicle winch comprises a winch control circuit interposed between a main circuit pressure inlet and the hydraulic connectors on the winch and governed by a pilot-operated directional valve. When a reel-out pilot valve shifts the pilot-operated directional valve, hydraulic flow to a reel-out port is permitted while flow to a reel-in port is obstructed. Conversely, when a reel-in pilot valve shifts the pilot-operated directional valve, hydraulic flow to the reel-in port is permitted while flow to the reel-out port is obstructed. A selectively configurable enabling circuit is interposed between the main circuit pressure inlet and the winch control circuit. In an enabling configuration, hydraulic flow from the main circuit pressure inlet to the pilot-operated directional valve, the reel-out pilot valve and the reel-in pilot valve is permitted. In a disabling configuration in which hydraulic flow to the pilot-operated directional valve is obstructed.

    Abstract: An improved optical device. The device has a gallium nitride substrate member comprising indium entities, gallium entities, and nitrogen entities. In one or more embodiments, the gallium nitride substrate member has an indium content ranging from about 1 to about 50% in weight. Preferably, the gallium nitride substrate member has a semipolar crystalline surface region or a non-polar crystalline surface region. The device has an epitaxially formed laser stripe region comprising an indium content ranging from about 1 to about 50% and formed overlying a portion of the semipolar crystalline orientation surface region or the non-polar crystalline surface region. The laser stripe region is characterized by a cavity orientation in a predefined direction according to a specific embodiment. The laser strip region has a first end and a second end including respective a first cleaved facet provided on the first end of the laser stripe region and a second cleaved facet provided on the second end of the laser stripe region.
