Publication number: 20200408681Abstract: An enclosure permits ingress of an infrared light beam and ultrasonic signal entering the enclosure from two different locations and facilitates their exit from the enclosure along a substantially similar egress path. The enclosure contains fluid which propagates the ultrasonic wave and a glass element which reflects the ultrasonic wave from its ingress direction onto an egress path. The fluid is an index matching fluid having a refractive index the same as the refractive index of the glass element, rendering the glass element transparent to the infrared light beam. Thus, the infrared light beam, having been induced into the enclosure on an entry path directed through the glass element, passes through the glass element without being reflected or refracted by it, placing the infrared light beam on a substantially similar path to that of the ultrasonic wave for egress of both waves from the enclosure at substantially the same point.Type: ApplicationFiled: June 25, 2020Publication date: December 31, 2020Inventor: Craig Newswanger

Publication number: 20200408723Abstract: A sensor or receiver array includes first and second pyroelectrically active electrodes formed of polyvinylidene difluoride and separated by a spacer layer that acts to electrically separate the pyroelectric layers while keeping them close enough such that they see effectively the same vibration or background acoustic excitation while maintaining sufficient separation to ensure that they generate significant differences in their pyroelectric responses. The structure provides two distinct signals (at separate timestamps), the difference between which provides a more accurate signal. An ultrasound detection system includes the tri-laminar sensor, disposed within a detection zone in which a test element can be positioned. The apparatus includes a processing unit, which comprises a detector unit coupled to the first and second pyroelectric elements and configured to derive a differential signal from the first and second pyroelectric elements.Type: ApplicationFiled: June 28, 2019Publication date: December 31, 2020Inventor: Bajram Zeqiri
