|20140216909||MECHANICAL VIBRATION SWITCH - A mechanical vibration switch having a magnet connected to a bar that rotates about an axis, an inertial mass connected to the bar, a magnetic material part disposed in a predetermined spaced apart relation from the magnet, a spring, a stop, and an electrical relay mechanically actuated by the bar. The magnetic material part is adjusted parallel to the magnet such that the magnetic force varies approximately linearly with the common surface area S between the face of the magnet and the face of the magnetic material part.||08-07-2014|
|20110079084||VIBRATION SENSOR WITH MECHANICAL ISOLATION MEMBER - An apparatus and system for sensing vibration in rotary or reciprocating machinery, such as motors, pumps, fans, gearboxes, compressors, turbo-machinery or high-speed spindles, which comprises a mechanical isolation member (||04-07-2011|
|20100244813||BRIDGE SENSOR WITH COLLOCATED ELECTRONICS AND TWO-WIRE INTERFACE - A transducer, including: a housing; a bridge sensor circuit disposed within the housing and including at least one micro electro-mechanical systems (MEMS) sensing elements and first and second output ports; circuitry disposed within the housing; and an input/output (I/O) line electrically connected to the circuitry, accessible at an exterior of the housing, and adapted for receipt of input voltage or current. The circuitry is for generating a single data signal that combines respective outputs of the first and second output ports, and transmitting the DC-coupled single data signal on the I/O line. The circuitry is for generating and transmitting to the bridge sensor circuit an excitation current or voltage using the input voltage or current.||09-30-2010|
