Abstract: A fluid activated shaft bulkhead seal system includes an annular carrier fixed with respect to a bulkhead and about a shaft extending through the bulkhead and the annular carrier. The annular carrier supports a pair of lip seals each of which defines an outwardly facing pocket and a lip portion spaced from the shaft and a portion abutting the carrier. A foam body is disposed in the pocket of each lip seal. Each foam body includes a gel material configured to expand in the presence of fluid urging the lip portions of the lip seals into contact with the shaft to seal the annular carrier with respect to the shaft. An annular retainer is mated to each side of the annular carrier for retaining the foam body in the pocket of each lip seal.

Abstract: Systems and methods associated with a fluid-activated shaft seal are provided. The systems, which feature multiple components, include a support component defining an exterior surface, a carrier component including an interior surface to slideably engage the exterior surface of the support component, and a seal disposed relative to the carrier component. The seal includes a lip portion and a fluid-responsive gel material that expands when exposed to a fluid to urge the lip portion towards or into contact with a shaft. The gel material contracts in the absence of the fluid to form or increase the size of a gap between the shaft and the lip portion. Methods of assembling and installing such a system are also described.

Abstract: Systems and methods for measuring a load in a structural element include placing at least one actuator and sensor on the structural element. The actuator is capable of exciting a wave of a predetermined frequency in the structural element and the sensor is capable of sensing the wave excited in the structural element. A computer control unit is applied to operate the actuator so as to excite a wave in the structural member in at least a first frequency, and to operate the sensor so as to measure at least one of a change in a resonance frequency in the structural element as a result of a change in loading on the structural member and a change in phase angle in the wave sensed by the sensor as a result of a change in loading on the structural member.

Abstract: Laser beam machining is applied to form arbitrarily shaped electroactive ceramics for transducers (e.g., electromechanical sensors and actuators). One particularly preferred embodiment of the invention comprises machining parallel grooves in a ceramic plate to improve flexibility. The grooves provide strain relief in bending by relieving Poisson strains transverse to the direction of bending. This embodiment offers the further benefit that planar anisotropy or directionality is introduced in the transducer. The machining process of the invention further enables the production of more complex geometries than those currently known in the art. Because of the flexibility of the machining process, virtually any desired transducer shape may be produced.

Abstract: In the hydraulically assisted steering system disclosed herein, a hydraulic pump for powering a steering servo is in turn driven either from the vehicle's engine, through an electrically controlled clutch, or by an electric motor which can drive the pump independently of the vehicle's engine. A signal is provided which varies as a function of vehicle's speed and disengagement of the clutch is enabled for vehicle speeds above a predetermable threshold, thereby to reduce energy consumption. The clutch is engaged, independently of vehicle speed, under high load, e.g. emergency situations.
