Detection of Conductive Material in a Thin Film 

• U.S. Patent # 9,383,439  

The invention addresses the detection of conductive materials, particularly in thin films, even when surrounded by non-conductive or other conductive materials. Traditional metal detection methods face challenges in discerning conductive thin films, especially in the presence of metallic or dielectric surroundings. The invention introduces a handheld, battery-operated device utilizing a novel single-frequency technique, high-frequency radio waves, and a wideband antenna to accurately detect conductivity in thin films. The device ignores interference from nearby conductive or non-conductive materials, providing a reliable method for identifying metallic or non-metallic properties in thin films, crucial for applications like window tinting in vehicles. The invention offers instant feedback to the operator, distinguishing the presence or absence of conductive material based on a simple yes/no status. The invention enhances the accuracy and efficiency of conductivity detection, overcoming limitations of traditional metal detection techniques in various environments.

Apparatuses for Rotating a Sensing Device​

• U.S. Patent #9,106,814 

The invention involves apparatuses for rotating a sensing device, such as a camera, about a pan axis and a perpendicular tilt axis. Traditionally, adjusting the field of view of a camera within an enclosure required disassembly, manual adjustment, and reassembly, posing contamination risks. The described apparatus provides a solution by incorporating dials for easy and contaminant-free adjustments. It includes an outer shaft with a first dial for pan adjustment and an inner shaft with a second dial for tilt adjustment. A frame assembly rotates about the pan axis and includes a base supporting the sensing device, allowing both pan and tilt adjustments without disassembly. The invention enhances the efficiency and convenience of adjusting camera orientations within enclosures, which is particularly useful for security or surveillance cameras. 

Training Aid

• U.S. Patent # 11,696,568

The invention addresses the need for reliable field detection of biological agents and toxins. Traditional canine detection is effective but faces challenges in training due to the inherent dangers of using actual biohazards. The invention introduces a method to create safe canine training aids by capturing volatile organic compounds released by a target biological agent or toxin in a polymer layer. The aid is then rendered safe through sterilization, allowing for reliable canine training without exposing them to the actual biohazard, and ensuring safety for handlers, canines, and the environment. The training aids have a long shelf life and are applicable to various biological agents and toxins, making them valuable for efficient field detection in high-risk areas. The invention contributes to enhancing detection capabilities for public health, agriculture, and animal health.
