Abstract: A marine survey apparatus comprises a plurality of cables towed by a vessel, the plurality of cables including two deflected tow cables each connected to the towing vessel. A primary surveying tool is attached to a cable, which cable is attached to the towing vessel and a spread rope. The deflected cables are connected to one another by the spread rope. The apparatus further comprises a water engaging drag device, which is attached to and trailed behind the spread rope. An elongate flexible element extends between the drag device and the vessel. The apparatus includes a control means for controlling the elongate flexible member and the drag device attached thereto. The survey apparatus is steerable to position the at least survey tool in a desired location by controlling the at least one drag device.

Abstract: A side frame for a loudspeaker rigging system has a frame structure mountable to the side of a loudspeaker, and links associated with the frame structure for linking together the corners of the frame structures of vertically adjacent side frames. The links associated with each side frame structure include a pivot link and splay adjustment link, each of which has a top extended end and a base end. Stow channels, which are preferably located in the bottom corner regions of the frame structure, contain the pivot link and splay adjustment link in the frame structure. A gripping structure associated with at least one, and preferably each link of the pivot and splay adjustment links allows a user to easily maneuver a link from its stowed to its deployed position.

The links associated with each side frame structure include a pivot link and splay adjustment link, each of which has a top extended end and a base end with a seating edge. Guide channels, which are located in the top corner regions of the frame structure to receive the base ends of a pivot link and splay adjustment link associated with a vertically adjacent side frame, have seating surfaces that conform to the seating edges at the base ends of the pivot and splay adjustment link. When base ends of these links seat in the guide channels, pin holes in the base end of the links self-align with pin holes in the corners of the frame structure for easy insertion locking pins.

Abstract: A method of connecting internal silver traces to external gold to produce a gold external side metal for a low-temperature co-fired ceramic package includes the deposition of a ruthenium dioxide cermet barrier layer between layers of gold and silver. An LTCC package constructed in accord with the inventive method has gold, ruthenium and silver layers that are parallel to the LTCC package surface and normal to and also electrically coupled to a conductive trace formed within the LTCC layers of the package.

Abstract: A method of estimating an internal temperature of a vehicle battery is based on heat transfer between a heat source and the battery. In addition to the heat source, airflow generated by vehicle movement and radiator fans affects the internal temperature of the battery. The method estimates an initial internal temperature of the battery at engine startup based on how long the engine was off. The temperature of the heat source is determined. A transfer function is determined to represent the effect of the airflow. The method updates a current internal temperature of the battery based on the initial internal temperature and an integration of the transfer function and the heat source temperature.

Abstract: An articulated vehicle is disclosed which includes first and second vehicle sections interconnected by an articulating linkage. The articulating linkage includes a universal joint and a cooperating pantograph linkage. The universal joint and the pantograph linkage define a vertically extending steering axis about which the vehicle sections are relatively pivoted to enable steering. The pantograph linkage comprises a first link bar pivoted to one vehicle section in substantial alignment with the steering axis and second and third link bars connected between respective end portions of the first link bar and connecting locations on the other vehicle section. A steering actuator is connected between the first link bar and the associated vehicle section and is operated to provide forces for steering the vehicle.
