Abstract: A system and method for registration of rotary drive shaft in a high-torque environment. The system utilizes a pair of connected harmonic drives to allow the clocking or registration of the rotary drive shaft without backlash and without requiring gearing changes as a result of a single harmonic drive. The pair of connected harmonic drives is coupled together by a tandem coupling.

Abstract: A power system for an unmanned surface vehicle includes a fuel cell including a fuel cell stack, where the fuel cell stack includes a fuel inlet. The power system also includes a fuel storage including at least one fuel-storage module fluidly connected to the fuel inlet of the fuel cell stack. The fuel-storage module is a source of energy for the fuel cell. The power system also includes a fuel and thermal management system fluidly connected to the fuel inlet of the fuel cell stack. The fuel and thermal management system includes a heat exchanger in thermal communication with the fuel cell stack for removing waste heat produced by the fuel cell stack during operation. The fuel and thermal management system also includes a flow valve, a pressure regulator, and a conduit.

Abstract: A power system for an unmanned surface vehicle is disclosed. In one embodiment, the power system includes a fuel cell, a fuel storage, and an air management system. The fuel cell includes a fuel cell stack. The fuel cell stack includes a fuel inlet, an air inlet, and an exhaust outlet. The fuel storage includes at least one fuel-storage module fluidly connected to the fuel inlet of the fuel cell stack. The fuel-storage module is a source of energy for the fuel cell. The air management system is fluidly connected to the air inlet and the exhaust outlet of the fuel cell. An air snorkel is part of the air management system and provides air to operate the fuel cell while the unmanned surface vehicle is deployed on a surface of a body of water. The air snorkel includes an intake and an exhaust.

Abstract: An antenna mount apparatus for use on a marine vessel for supporting and angularly positioning an antenna is provided. The apparatus includes: a housing configured to mount the apparatus to a support structure; a bi-directionally rotatable driver mounted on the housing; a worm configured to be rotatably driven by the driver about a first axis; a rotatable member having gear teeth at least partially around a periphery of the rotatable member, and configured to be driven about a second axis perpendicular to the first axis in response to rotation of the worm; and a rotatable antenna support member mounted on the rotatable member configured to support an antenna and to rotate in response to the rotatable member, the antenna support member being rotatable between a substantially horizontal position and a substantially vertical position.

Abstract: A system for distributing asphalt includes a vehicle and a distribution compartment coupled to the vehicle. The distribution compartment includes a support member, a laterally elongated element coupled to the support member, and two or more lateral containment members operatively coupled to the support member for inhibiting the escape of asphalt from the distribution compartment when asphalt is contained therein. At least one of the lateral containment members is laterally movable towards or away from one at least one other lateral containment member.

Abstract: A spinal rod connector is disclosed that allows end-to-end connection of at least two spinal rods. The connector may allow for angular adjustment in the construct which is associated with the patient's anatomy. Percutaneous length adjustment of the spinal rods may be available with visual assessment of the length of the rods via viewing windows on the connector. A locking mechanism may be used to fix a determined angle of the connector dependent upon the anatomy of the patient. The angle may be adjusted if necessary during a subsequent procedure.

Abstract: The present application is directed to embodiments of a pedicle screw assembly to position an elongated member within a patient. The assembly may include a receiver with a channel sized to receive the elongated member and a chamber. The assembly may also include an anchor with a head sized to fit within the chamber. The assembly may include a compression member sized to fit within the chamber and include a first side that contacts against the head and a second side that contacts against the receiver. At least one of the receiver, anchor, and compression member may be constructed of a first material, and at least one of the receiver, anchor, and compression member may be constructed of a second material. The first and second materials may include different moduli of elasticity to prevent deformation of the assembly.

Abstract: A holder for an outrigger is disclosed which has a housing for mounting the holder on top of a structural part of a boat. The holder can be rotated in a horizontal plane to various fixed positions by means of a rotatable, retractable handle positioned below the structural part of the boat. The weight of the holder is taken by in internal structure of the housing, such that, during rotation to another position, the holder weight is not transferred to the handle; thereby making it easier to rotate the holder.
