Title: The Innovations of Donald L Brand
Introduction
Donald L Brand is a notable inventor based in Bend, Oregon. He holds a total of 3 patents that showcase his contributions to technology and innovation. His work primarily focuses on advancements in digital time bases and optical detection systems.
Latest Patents
One of his latest patents is titled "Digital time base with corrected analog interpolation." This invention provides a variable reference voltage to ensure that the period of an analog ramp is equal to the time interval between range clock pulses. The method involves determining a time base error by establishing a zero reference level on a test pulse and a maximum level corresponding to the maximum value of the analog ramp. A microprocessor then provides a corrected reference voltage to equalize the maximum delay of the analog ramp with the clock pulse interval.
Another significant patent is the "Optical detector with storage effects reduction." This invention improves optical detection by inserting an optical modulator between the optical signal and the detector. The modulator is typically off and only activated during the sampling period, which helps to reduce storage effects in the optical detector.
