Title: David Purdy: Innovator in Wireless Technology

Introduction

David Purdy is a notable inventor based in Westminster, CO (US). He has made significant contributions to the field of wireless technology, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is titled "Method and apparatus for automatic gain control of a wireless receiver." This invention provides a method for compensating gain control operations during disruptions in received signals. The automatic gain control circuit remembers control state information from just before a disruption, allowing it to reset or maintain control during the disruption. This ensures that the receiver gain control signal remains accurate and effective.

Another significant patent is the "Oscillating circuit and method for calibrating same." This invention involves a quartz crystal oscillator that generates a clock signal synchronized to a master signal during lock-in periods. When access to the master signal is lost, the oscillation frequency function predicts the crystal oscillation frequency based on physical parameters like time and temperature. The predicted frequency is then compared to a standard frequency to generate an error signal, which is used to calibrate the oscillation signal of the circuit.
