Abstract: An ultrasonic measuring device for the measurement of a flow of a fluid, includes a measuring tube, a first chamber and a second chamber. The measuring tube has a central axis, which defines a flow direction for the fluid; The first chamber has a first ultrasonic transducer arranged therein. The second chamber has a second ultrasonic transducer arranged therein. The measuring tube includes an inlet and an outlet for the fluid. The first ultrasonic transducer and the second ultrasonic transducer bound a rectilinear measuring section for the fluid, the first chamber and the second chamber being configured and arranged such that the fluid is capable of flowing around each of them. The first ultrasonic transducer and the second ultrasonic transducer are arranged such that the measuring section extends in the flow direction.

Abstract: A method for providing illumination to a timepiece includes providing an array of LEDs arranged around a periphery of a substantially planar surface such that each LED in the array of LEDs emits light toward a center of the periphery. The substantially planar surface overlays a timepiece movement having a watch hand pinion that extends through a hole in the substantially planar surface. The substantially planar surface is bounded by a casing of the timepiece. The method also includes situating each of the LEDs in a diffuser layer extending across the substantially planar surface to scatter light emitted by each LED. The method also includes applying power to the array of LEDs such that each LED is driven at a current lower than a specified current for normal operation of the LED.

Abstract: It has been found that target optics produce non-specular, augmented optical returns when interrogated by a laser pulse. This non-specular radiation is detected by an active laser search system employing a direct-reading, thresholded focal plane detector that is able to detect non-cooperating targets with optics that employ a detector or optical element at the focal plane of their receiving optics. The pulses returned from such target optics have a width commensurate with the original transmitted pulse width, whereas passive background noise and the spread out active returns from the ground exhibit temporally long returns. By setting the sensor threshold sufficiently high, the system discriminates against noise and clutter while at the same time reducing the number of sweeps required to detect a target within the search area.

Abstract: A sensor is provided for analyzing an object at a focal point of a lens. The sensor includes a focused radiant energy source directed at the lens. The focused radiant energy source transmits a first beam of energy to the lens, vaporizing a portion of the object at the focal point of the lens. A second beam of energy is emitted from the vaporization of the object. A spectrometer is positioned to receive the second beam of energy emitted from the object. The second beam of energy is at least partially transmitted anti-parallel to the first beam of energy.

Abstract: A focal plane architecture is provided which includes direct reading of an array of infrared detectors, each coupled to its own threshold circuit, the output of which is coupled to one input of a NAND gate, with the other input to the NAND gate being provided with a delayed threshold circuit output, thus to permit discrimination against ground clutter. This architecture results in an ultra fast frame read out, inherent discrimination of compact targets, photon counting at infrared wavelengths, and programmable range gating by exterior selection of array events within an expected return time for a transmitted pulse.
