Abstract: The SAW sensor in a stainless steel button package having a diaphragm and mounted on a threaded port. Package can hermetically seal a sensor and RFID-antenna assemblies from media. Sensor diaphragm is exposable to media. Sensor and RFID antennas communicate electrically with SAW sensor and RFID device, respectively, for sensor measurements and identification. Antennas receive RF interrogation signal from a nearby interrogator/transceiver and send reflected RF signals back to the interrogator unit containing sensor measurement and sensor ID. TRF signal excites a SAW resonator inside the sensor and causes the SAW to resonate wherein resonant frequency changes with pressure and temperature applied to the sensor. Antennas could be printed circuit board antennas, helical antennas, loop antennas, any other commercially available off-the-shelf antennas or a combination of these.

Abstract: A wireless and batteryless pressure sensor apparatus comprises of a SAW sensor and an antenna mounted on a printed circuit board. Optionally, and RFID tag in used in combination with the SAW sensor. A sensor antenna and a RFID antenna can be located on the printed circuit board such that the antennas communicate electrically with the sensor and the RFID device. The sensor can be interrogated utilizing a radio frequency, which is used to excite a SAW crystal inside the sensor. The interrogation signal causes the SAW to resonate wherein a resonant frequency changes with the pressure and temperature that is applied to the sensor. An interrogator can receive a return (echo) signal representing a change in SAW sensor properties (e.g., diaphragm change). A printed circuit board can be mounted on a stainless steel port and overpackaged with standard processes for hermetically sealing the sensor, or sensor and RFID device with at least one antenna.

Abstract: A photosensor is provided with a control circuit that is capable of varying the frequency of light pulses which energize a light source of the sensor. When four consecutive light pulses result in an identical status of a light sensitive component, the frequency of light pulses is slowed to conserve energy. However, when a change in state is recognized by the circuitry of the present invention, the frequency of light pulses is increased in order to more rapidly determine whether or not a change of status has actually occurred. This permits the photoelectric sensor to conserve energy while also being able to rapidly determine whether or not the light path of the photoelectric sensor has changed state from obstructed to unobstructed or, conversely, from unobstructed to obstructed.

Abstract: A voltage regulator circuit is provided for a sensor that is connected in a two-wire scheme to a circuit comprising a power supply and a load. The circuit regulates the current flowing through the load when the sensor output is inactive and provides power to the sensor during periods of time when the input power of the regulator circuit is insufficient to do so. A current monitor and a voltage monitor are provided which utilize common circuit elements to control the current flowing through the circuit. The operational characteristics of a MOSFET device are used advantageously to control the magnitude of current flowing through the sensor and regulate the current as a function of both the magnitude of current and the magnitude of a voltage potential across a bulk capacitor.
