This technology overcomes several serious difficulties related to aligning and attaching transducers on opposite sides of a barrier like a submarine hull or the like, when the vessel is in a body of water, or other barriers where one or both sides of the barrier may be in a hostile environment, such as under high pressure, high temperature or nuclear conditions, or a liquid environment. This technology utilizes mounting members with threaded bolt holes at their periphery.

This technology relates to ultrasonic transducer arrangement for transmitting and receiving ultrasonic data and power to and from a barrier. Many transducer designs suffer from uneven pressure between critical surfaces, which results in warped components and degraded performance. This technology provides a transducer design that avoids these issues and provides improved performance in high temperature andor high pressure environments.

This technology relates to a full spectrum broad wavelength emission white light source fabricated using a graded composition optically clear substrate that enables high efficiency, high flux, narrow or wide spectral width, large area, low cost LEDs with
