| 20120105054 | DC RESPONSIVE TRANSDUCER WITH ON-BOARD USER ACTUATED AUTO-ZERO - An accelerometer is provided having a power circuit, a detection circuit, and a compensation circuit. The compensation circuit is operative to measure an offset voltage occurring between an output reference voltage from the power circuit and an output voltage from the detection circuit state, store the offset voltage during a zero acceleration, and output the stored offset voltage to alter the output voltage of the detection circuit. | 05-03-2012 |
| 20120086581 | WATER MONITORING SYSTEM - A water monitoring system includes a plurality of remotely-located nodes for measuring water characteristics, and transmitting measured data to a central gateway device over at least one local RF connection. The gateway is operative to transmit cumulative data received from the plurality of nodes over a single cellular or satellite connection to a central processing system. | 04-12-2012 |
| 20110233392 | METHOD AND SYSTEM FOR USING LIGHT PULSED SEQUENCES TO CALIBRATE AN ENCODER - An encoder to be mounted to a piston meter and configured to compute a volume of distributed fluid includes a light sensor configured to detect a light sequence and output signals indicative of the light sequence to a processing device, the processing device configured to determine if the light sequence is one of one or more authorized light sequences, wherein the processing device enters a calibration mode if the light sequence is one of the one or more authorized light sequences. | 09-29-2011 |
| 20110148399 | ENCODER USING MAGNET DROP OUT FEATURE FOR THEFT DETECTION - An encoder to be mounted to a shaft extending from a piston meter configured to compute a volume of distributed fluid includes a magnet affixed to the shaft via a floating magnet holder, a magnetic sensor configured to sense the flux density and direction of a magnetic field created by the magnet and to output a signal indicating the flux density and direction of the magnetic field to a printed circuit board, and the printed circuit board configured to output a signal indicating the volume of distributed fluid if the encoder has not been tampered with and configured to output an error signal if the encoder has been tampered with. | 06-23-2011 |
| 20090212899 | Low Pressure Transducer Using Beam and Diaphragm - A low-pressure transducer including a disc-shaped metal diaphragm to which a fluid pressure is applied, wherein the diaphragm contains a raised beam formed by thinning the entire exterior surface of the diaphragm except for the beam; and at least one silicon strain gage glass bonded to the beam, wherein the low-pressure transducer can accurately gage pressures at least as low as 15 psi. The present invention also comprises a method for manufacturing a pressure transducer including the steps of forming a cylindrical diaphragm having a top surface and a lower surface; establishing a diameter and a thickness of the diaphragm relative to an operational plane by a creating a hole axially through the transducer body that terminates at the lower surface; and creating a raised surface in the shape of a cross beam integral to the operational surface; and bonding one or more strain gages thereupon. | 08-27-2009 |
| 20090147627 | MULTILAYER BACKING ABSORBER FOR ULTRASONIC TRANSDUCER - A multilayer backing absorber for use with an ultrasonic transducer comprises an elemental multilayer having at least one metal layer and at least one adhesive layer, wherein the backing absorber is adapted to be coupled to a vibrating layer of the ultrasonic transducer. | 06-11-2009 |
| 20080278353 | TAMPER RESISTANT ELECTRONIC TRANSACTION ASSEMBLY - A tamper resistant user interface device includes a substantially planar sensor. The sensor includes a plurality of user activated membrane switches. At least one multilayer structure is folded around and overlays the planar sensor. The structure includes at least one layer to detect tampering with the sensor. | 11-13-2008 |
