Abstract: Methods and apparatus to control aircraft horizontal stabilizers are described herein. One described method includes calculating, using a processor, a desired movement of a horizontal stabilizer of an aircraft to counteract a pitching moment of the aircraft, and controlling the horizontal stabilizer based on the desired movement.

Abstract: A modular welding system for performing quick, easy and high quality welds. The modular welding system comprises a basic component system and a modular fixture component system. The basic component system provides the basic components which are needed to perform a quality weld efficiently. The modular fixture component system interfaces with the basic component system and provides a particular welding fixture assembly that performs a particular type of weld. More particularly, a stiffener type modular fixture component system and a butt/tee type modular fixture system are described. However, any other particular fixture type system may be integrated with the basic component system of the present invention.

Abstract: The present invention relates to a high deposition submerged arc welding system, comprising a gantry fixture, a weldhead, an operator control module and a modular control system. The gantry fixture is configured to receive a first plate and a second plate. The weldhead is operatively coupled to the gantry fixture and welds the first plate and second plate together with a metal powder, a welding wire and a flux. The operator control module is configured to receive a program for welding the first plate and the second plate together. The modular control system has a common bus which communicates the program to a plurality of control modules.

Abstract: The present invention provides a simple, relatively inexpensive improved portable patient monitoring system that alerts a nurses station as well as the patient when the patient attempts to exit the hospital bed but that has no electronic components attached to the hospital bed. The portable patient monitoring system of the present invention comprises a portable master unit having an infrared emitter which emits an infrared beam and infrared detector which detects the infrared beam. The portable patient monitoring system of the present invention further comprises a portable external reflector which reflects the infrared beam emitted from the infrared emitter back to the infrared detector.
