Abstract: A method and apparatus for controlling the motion of a cable-driven autonomous moored profiler. The profiler includes one or more buoyant members for buoying the profiler in the fluid, a winch, and a feedback controller for controlling the winch. The winch includes a spool, a device providing for varying rates of turning of the spool, and a flexible cable for winding onto and unwinding from the spool. A first end of the cable is carried by the profiler. The controller monitors an indication of the tension in the cable and controls the device in response thereto.

Abstract: A lamp—suitable for use within a projector or other high-light output application—includes an ultra high pressure bulb. An extension from the bulb defines a start-up bubble. A conductor is carried by the extension of the ultra high pressure bulb, generally enclosing the start-up bubble, thereby exciting gas contained within the start-up bubble. A header defines a socket within which the extension and the conductor are carried.

Abstract: A motor hub is disclosed. The motor hub comprises a housing for a motor. The housing is rotatable around an axis of rotation of the motor. The motor hub also has marks arranged on a surface of the housing, and spaces between the marks. The marks and spaces form a pattern readable for sensing a rotational speed of the motor.
