Abstract: Apparatus and associated methods relate to a seeker for a Semi-Active Laser (SAL) guided missile. The seeker has a Short-Wave InfraRed (SWIR) camera and a Pulse Timing Logic (PTL) detector. The PTL detector has a SWIR photo detector axially aligned with a lens stack of the SWIR camera. The SWIR photo detector is configured to detect a sequence of SWIR pulses generated by a SAL target designator and reflected by a designated target. The PTL detector has a pulse timer configured to identify a sequence pattern of the detected sequence of SWIR pulses, and to predict a timing of a next SWIR pulse in the identified sequence pattern so as to synchronize exposure of the SWIR camera to capture a next image of the designated target at the predicted timing of the next SWIR pulse. Such exposure timing can advantageously improve the signal to noise ratio of the next image.

Abstract: A sensor assembly comprises a remote data concentrator (RDC) and an optically powered transducer module (OPTM). The RDC transmits a first optical pulse including a parameter request signal along an optical fiber. The OPTM is connected to the optical fiber, and comprises a photodiode, an energy storage device, a sensor, a processor, and a laser. The photodiode receives the first optical pulse, and the energy storage device is charged by the photodiode. The sensor, processor, and laser are powered by discharging the energy storage device. The sensor senses a parameter specified by the parameter request signal. The processor generates a signal packet from the output of the first sensor. The laser transmits a second optical pulse including the signal packet along the optical fiber to the RDC

Abstract: A differential pressure sensor may include a body with a first end, second end and wall wherein the first and second ends comprise isolator diaphragms connected to first and second process fluid inlets. A MEMS pressure sensor including a pressure sensing diaphragm with first and second sides may be mounted on a hollow pedestal adhesively attached to an annular bottom of a cylindrical cavity wherein the first side of the sensor is coupled to the first isolator diaphragm by a first fill fluid and the second side of the sensor is coupled to the second isolator diaphragm through the interior of the hollow pedestal by a second fill fluid volume wherein the first and second fill fluid volumes are separated by an adhesive seal between the bottom of the cylindrical cavity and the bottom of the hollow pedestal wherein the cylindrical cavity comprises a first cylindrical wall with a first diameter in contact with the annular bottom, a frustroconical portion in contact with the first cylindrical wall and in contact with a second cylindrical wall with a second diameter larger than the first diameter such that the increased distance between the pedestal and the cylindrical wall prevents adhesive moving up the space between the pedestal and cavity wall from the bottom of the cavity when the pressure sensor and hollow pedestal are mounted in the cavity. The sensor further includes sensor elements on the MEMS diaphragm that provide an indication of pressure differences between the first and second process fluids.

Abstract: Apparatus and associated methods relate to aligning a taxi-assist camera such that each image frame of real-time video that the camera generates has a standard presentation format. The taxi-assist camera is configured to be mounted on an aircraft and oriented such that each image frame includes both a specific feature of the aircraft and of nearby objects external to the aircraft. The specific feature of the aircraft is detected and a location within the image frame of the specific feature is determined. The determined location within the image frame is compared with a reference location. A transformation operator is generated to transform the image frame such that the specific feature of the aircraft will be located within the image at a location corresponding to the reference location. The transformation operator is then applied to each of the image frames of the real-time video that the camera generates.

Abstract: Apparatus and associated methods relate to determining liquid-water concentration in a cloud atmosphere based on a frequency of resonance of a magnetostrictive resonator and/or a temporal variation of the resonant frequency of the magnetostrictive resonator. The magnetostrictive resonator is configured to resonate at a resonant frequency indicative of a measure of ice accumulation upon an exterior surface of the magnetostrictive resonator. When in liquid-water ambient, however, the magnetostrictive resonator has a resonant frequency less than a baseline resonant frequency. When in the liquid-water ambient, the magnetostrictive resonator also has temporal variations in resonant frequency that exceed one part in ten thousand. Using one or both of these resonant-frequency responses to liquid-water ambient, a signal indicative of liquid-water content can be generated.

Abstract: Apparatus and associated methods relate to generating a signal indicative of a differential pressure using a first absolute pressure sensor and a second absolute pressure sensor, each having a positive relation transducer configured to generate an electrical signal that increases in response to increasing pressure and a negative relation transducer configured to generate an electrical signal that decreases in response to increasing pressure. The first and second positive relation transducers of the first and second absolute pressure sensors, respectively, are electrically connected as a first leg of a Wheatstone bridge at a first output node. The first and second negative relation transducers of the first and second absolute pressure sensors, respectively, are electrically connected as a second leg of a Wheatstone bridge at a second output node. Both positive and both negative relation transducers are connected to a first and a second bias node of the Wheatstone bridge, respectively.
