Introduction

Jason J Hoendervoogt is an accomplished inventor based in Phoenix, AZ. He holds three patents that showcase his expertise in digitizer technology. His work has significantly contributed to advancements in the field of electronic instruments.

Latest Patents

One of his latest patents is a "Digitizer with capacitive and inductive coupling." This invention features a battery-powered oscillator in a freely movable pointer that drives a coil and a divider. A grid of spaced conductors in a base unit is inductively coupled to the coil. A conductive plate that lies parallel to the conductor grid capacitively couples the signal from the divider to a phase-locked loop, providing a reference signal that maintains a constant phase in relation to the oscillator. The detection circuitry utilizes the signals induced in selected grid conductors and the phase reference signal to determine the pointer's location relative to the conductors. An alternative method involves combining the signal induced in an idle reference conductor with the capacitively coupled reference signal to aid in demodulating the induced signals. Additionally, the coil may be driven by a signal capacitively coupled from the base unit instead of using an oscillator in the pointer.

Another notable patent is the "Position digitizer circuit for a moveable instrument." This invention is a digitizer circuit in a peripheral system for a computer, comprising a moveable instrument and a planar grid. An excitation signal in either the instrument or grid generates an induced signal in the other, with the phase difference between the excitation and induced signals indicating the instrument's position relative to the grid. The system includes means for summing the excitation and induced signals to produce a sum signal, along with means for generating an output signal whose frequency is a function of the amplitude of the sum signal.
