Title: Innovations of Donald P Labriola, II

Introduction

Donald P Labriola, II is a notable inventor based in La Verne, CA (US). He holds a total of 12 patents that showcase his contributions to the field of technology and engineering. His work primarily focuses on advancements in antenna technology and position sensing systems.

Latest Patents

One of his latest patents is the "Compact Frequency Adjustable Portable Antenna." This innovative antenna is designed to quickly and quietly self-adjust to minimize Voltage Standing Wave Ratio (VSWR). It features a compact tuning coil and a rolling contact, with a reentrant cap serving as a capacitive top hat. The spiral cut enhances the efficiency of this very short antenna. Additionally, a tough insulating tube covers the antenna to protect the user from RF burns. The use of rolling contacts on a smooth inside diameter of the tuning coil significantly reduces the force required to move the contactor, as well as the acoustical noise generated during tuning. A controller drives a servo motor to position the contactor optimally within the tuning coil and selects the impedance to connect between the unused end of the tuning coil and the feed point of the antenna to optimize VSWR.

Another significant patent is the "Integrated Multi-Turn Absolute Position Sensor for High Pole Count Motors." This invention integrates absolute multi-turn position sensing within the structure of a hybrid stepper motor by sharing the magnetic structure of the motor with the sensing means. An alternating magnetic field is generated from a single magnet within the stepper motor rotor, utilizing alternating flux paths directed to large Barkhausen jump effect sensing elements. The pulses generated from the large Barkhausen sensing are decoded electronically and stored in non-volatile memory to accurately locate the motor position within a fraction of one electrical cycle over an arbitrary range. This coarse position sensing can be enhanced by using a higher resolution absolute within-electrical-cycle sensing means to provide integrated high-resolution position sensing over an arbitrary number of revolutions.
