Abstract: The disclosed technology relates to imaging catheters. A method is provided that includes: receiving, from a plurality of transducers disposed on a catheter probe, a corresponding plurality of analog signals; selectively sampling the plurality of analog signals; multiplexing to produce a sequence of samples; and transmitting the sequence of samples to a receiver circuit. The receiver circuit includes a clock; an analog to digital converter (ADC) in communication with the clock; and a sampling phase correction circuit in communication with the clock and the ADC. The method further includes: determining optimum sampling times based on measured signal delays associated with the system; adjusting a phase of the clock based on the measured signal delays; and communicating the phase-adjusted clock to the transmitter circuit for the selective sampling of the analog signals. Certain embodiments of the disclosed technology may further be utilized in conjunction with beamforming.

Abstract: An erosion control transition mat for reducing scour and destructive erosion at the transition between hard armor and soft armor erosion control surfaces. The erosion control transition mat is provided with a riser and a plurality of voids which collect to slow and divert effluent from the hard armor to reduce scour and impact on the soft armor. The erosion control transition mat is lightweight and of a low-cost manufacture, and may be installed without the need for large equipment.
