Abstract: Immersible ultrasonic probes and methods of making are disclosed that provide nondestructive examination, imaging, and assessment of submerged targets in various liquid media including corrosive and optically opaque media at harsh conditions. In one embodiment the probe is a phased-array ultrasonic testing probe that includes an array of piezoelectric elements configured to transmit ultrasonic signals at selected frequencies through an opaque medium that enables nondestructive examination, characterization, and imaging of targets in the opaque medium.

Abstract: A system, method, and device are described for ultrasonic treatment of viscous fluids, including, e.g., crude oils that provide a variety of desired modifications. The invention includes a container having a circumvolving outer wall configured to allow passage of a quantity of a material within a passageway therein and ultrasonic transducers that attach to and circumvolve the outer wall of the container. The ultrasonic transducers transmit ultrasonic energy into material within the container at preselected frequencies thereby achieving desired effects.

Abstract: Systems and techniques for detecting the presence of foreign material in food utilizing optical backlighting and/or ultrasonic inspection are presented. In optical backlighting, a substantially monochromatic light source optically backlights a food stream with source light having a wavelength between about 500 and 600 nm. An image of the food stream is captured and the presence of foreign material is determined when a portion of the detected image exceeds a predetermined threshold. The technique is especially suitable for the detection of bone in chicken meat, and the light source can be a planar array of green LEDs. In ultrasonic inspection, a process stream is interrogated with pulses of ultrasound and the presence of foreign material is determined based on the detected off-angle ultrasound scattering response.

Abstract: A multiparameter acoustic signature inspection device and method are described for non-invasive inspection of containers. Dual acoustic signatures discriminate between various fluids and materials for identification of the same.

Abstract: A method and apparatus are described for determining the doneness of food during a cooking process. Ultrasonic signal are passed through the food during cooking. The change in transmission characteristics of the ultrasonic signal during the cooking process is measured to determine the point at which the food has been cooked to the proper level. In one aspect, a heated fluid cooks the food, and the transmission characteristics along a fluid-only ultrasonic path provides a reference for comparison with the transmission characteristics for a food-fluid ultrasonic path.

Abstract: An ultrasound inspection apparatus particularly adapted to examine containers (sealed or unsealed) containing a liquid or solid bulk material. The apparatus has an overall configuration of a hand held pistol with a front transducer contact surface that is positioned against a front wall of the container. An ultrasound pulse is transmitted from the apparatus to be reflected from a back wall of a container being investigated. The received echo pulse is converted to a digital waveform. The waveform is analyzed relative to temperature, travel distance of the pulse(s), and time of travel to ascertain characteristics of the liquid or other materials and to provide identification of the same.

Abstract: A system and technique for detecting the presence of foreign material is presented. An ultrasound transmitter interrogates the bulk material and an array of detectors receives the off angle ultrasound scattering response of the bulk material. The presence of foreign material is determined when the off angle scattering response exceeds a predetermined threshold. The technique is especially suitable for the detection of bone in meat.
