Low cost miniature vector sensors are provided. An acoustic vector sensor is provided that comprises at least one accelerometer to measure at least one component of acoustic particle acceleration, wherein the at least one accelerometer has a resonant frequency within a measurement band of the acoustic vector sensor. In addition, a method is disclosed for measuring an acoustic signal. The method comprises the steps of configuring an array of acoustic vector sensors comprised of at least one accelerometer to measure at least one component of acoustic particle acceleration; operating the at least one accelerometer at a resonant frequency within a measurement band of the acoustic vector sensor; and generating a voltage using one or more of the acoustic vector sensors representative of the acoustic signal as the acoustic signal propagates past the array. The voltage optionally indicates a bearing of the acoustic signal.

In an inductive sensor a ferrous core is provided and has generally opposed first and second ends. A winding assembly surrounds the core. First and second magnets are coupled to the first and second ends of the core and are oriented relative to one another so that like magnetic poles are opposing one another along a length defined by the core.

A performance measuring system for a rotating shaft comprises a first annular support assembly to be coupled adjacent to a first end of a rotating shaft inwardly of associated shaft bearings. A second annular support assembly is to be coupled adjacent to a second end of a rotating shaft inwardly of associated shaft bearings. A third annular support assembly is to be coupled to the rotating shaft between the first and second support assemblies. A laser source is mounted on the first annular support assembly. A laser detector is mounted on the second annular support assembly. First and second magnetic sensors for detecting the Earth's magnetic field are mounted respectively on the first and second annular support assemblies. An accelerometer is mounted on the third annular support assembly for generating a fourth detection signal.

Performance measuring system and method for analyzing performance characteristics of rotating shafts

Hydrocraft, capable of maintaining comfortable seaworthy performance at both low and high speeds, in both calm and rough seas, wherein its hull form coordinates high efficiency of at least two zero deadrise planing surfaces with a wave piercing, wedge effect bow segment. The forward portion of the respective concave sides of the bow intersect at the centerline of the hull. The sides of the forward body of the hull rise from the bottom at the chine, vertically then upwardly and outwardly in a concave curvature, the form of which will load the side skin in tension. At a preselected point above the hull bottom, the sharp edged bow is truncated in a conical, forward sloping surface to provide an upward hydrodynamic force to lift the hull over waves which are higher than the gunwale. The parallel after body is located above the after planing surface, and a conical transom closes the stern. The two zero deadrise planing surfaces, of fluted section will present a positive angle of attack to the water surface when the hull has a zero angle of trim. The craft planing surfaces are step connected.
