Introduction

James B Abshire is a notable inventor based in Laurel, MD (US), recognized for his contributions to technology and engineering. With a total of 5 patents, he has made significant advancements in various fields, particularly in measurement and surface profiling technologies.

Latest Patents

One of his latest patents is titled "Time delay and distance measurement." This innovative method involves providing an electromagnetic radiation carrier frequency and modulating various parameters such as amplitude, phase, frequency, polarization, and pointing angle with a return to zero (RZ) pseudo random noise (PN) code. The RZ PN code features a constant bit period and a pulse duration that is less than the bit period. A receiver detects the electromagnetic radiation and calculates the scattering profile versus time or range by computing a cross-correlation function between the recorded received signal and a three-state RZ PN code kernel. This method can also be applied to pulse delay time communications.

Another significant patent is the "Method and system for determining surface profile information." This system is designed to determine the surface profile of an object and is particularly useful in industrial robots, such as automatic welders. The system is built to withstand severe operating environments, requiring a vision system with noise immunity and accuracy. A beam splitter allows the use of discrete optical detectors, which resolve many issues associated with previously used detectors, such as diode arrays and TV cameras. Additionally, an automatic gain control adjusts the intensity of a generated optical beam in response to the surface's reflectivity, enhancing the accuracy and noise immunity of the optical vision system for demanding industrial applications.
