Latest Patents

One of his latest patents is the Gravity Actuated X-ray Scanner. This digital scan projection radiography system is particularly adapted for portable deployment. The system scans by gravity, utilizing a cam mechanism that raises the pivot of a pivotally suspended scanner assembly. This assembly includes the source, detector, and other components, rendering gravitational potential energy approximately linear with respect to angular scanning displacement. This feature enables the limitation of scanning angular velocity to a constant value with the aid of only a friction brake. Additionally, it causes the detector scanning path to more closely approximate a linear path than an arcuate path, which would result from simple pivotal pendulum scanning.

Another significant patent is the Radiation Data Acquisition system. This radiation imaging system features a radiation source that directs a thin spread beam of radiation toward a detector assembly aligned with the radiation beam. The detector assembly includes a printed circuit board with a bowed configuration and bearing board circuitry. An array of photodiode detector elements is attached to the board, which includes a front and a rear array of elements arranged one behind the other. The circuit board defines a slot between the front and rear arrays, allowing a radiation filter to be removably and slidably interposed. The detector elements are recessed in the outer surfaces of the circuit board, ensuring that contact fingers of the elements are flush with the unrecessed surface of the board. Radiation-sensitive phosphor material is positioned over each of the respective front and rear detector element arrays.
