Latest Patents

Nguyen's latest patents include a "System and method for optical port inspection for telecommunication systems and devices." This invention relates to a system and method for in situ inspection of optical ports for occlusions that might impede an optical signal. The invention utilizes a mini-borescope with an insertion tube of less than two millimeters in diameter. The mini-borescope may utilize a video camera for capturing images of the target and adjustably magnifies the target image for display. Additionally, a plurality of component type borescope-to-optical port adapters is coupled to the mini-borescope insertion tube, allowing for compatibility with various optical components. The design also includes a protective sleeve that enhances the rigidity of the insertion tube, reducing the risk of accidental bending during insertion.

Another significant patent is the "High current test signal converter circuit." This interface circuit converts high current output signals from test equipment to corresponding low voltage signals for testing digital relays used in power transmission systems. The circuit includes a current sensing resistor that converts high current output signals to low voltage signals, which are then amplified to the appropriate voltage level. The gain of the amplifier is adjustable, making the circuit versatile for different digital relays with varying input signal requirements.
