Patent number: 11061135Abstract: A method for detecting a buried non-conductive pipe includes transmitting, by a radio frequency (RF) transmitter, guided RF energy through one end of the non-conductive pipe, receiving, by a RF receiver, electromagnetic signals due to RF energy leaks in one or more locations along the non-conductive pipe, and processing, by one or more processors, the received signals to determine a location of the non-conductive pipe. A system for detecting a buried non-conductive pipe includes a RF transmitter configured to transmit guided RF energy through one end of the non-conductive pipe, a RF receiver configured to receive electromagnetic signals due to RF energy leaks in one or more locations along the non-conductive pipe, and one or more processors configured to process the received signals to determine a location of the non-conductive pipe.Type: GrantFiled: November 9, 2018Date of Patent: July 13, 2021Assignee: Heath Consultants IncorporatedInventors: Ben Allen Abbott, Donald R.

Patent number: 10445930Abstract: A method of using a learning machine to provide a biomechanical data representation of a subject based on markerless video motion capture. The learning machine is trained with both markerless video and marker-based (or other worn body sensor) data, with the marker-based or body worn sensor data being used to generate a full biomechanical model, which is the “ground truth” data. This ground truth data is combined with the markerless video data to generate a training dataset.Type: GrantFiled: May 17, 2018Date of Patent: October 15, 2019Assignee: Southwest Research InstituteInventors: Kase J. Saylor, Daniel P. Nicolella, David R. Chambers, Travis D. Eliason, Donald R. Poole
