United States Patent: 10,040,437
Brake Control Unit
This patent is a continuation of U.S. patent number 8,746,812. Towed vehicles can be extremely heavy. Accordingly, it is too much of a burden to the braking system of a towing vehicle to not have brakes on the towed vehicle. Controlling the brakes of the towed vehicle must be accurately applied otherwise undesirable conditions can be created. There is a need for a method for controlling braking of a towed vehicle. This method comprises receiving a first signal via a communication bus of a towing vehicle, the first signal relating to at least one operating condition of at least one the towing vehicle and a towed vehicle, sending a second signal to brakes of the towed vehicle, the second signal based on said first signal.
One of ten inventors on this patent.
Approximately 300K units produced per year using this patent.

Electric energy meter with power outage recovery circuit
A time registering electric energy meter for measuring usage of an AC energy quantity includes primary and secondary DC power supplies and a microprocessor, having a realtime clock maintained by the 60 Hz AC energy quantity, for maintaining realtime and for generating AC energy usage information determined by a number of time-related events. The meter further includes power outage recovery circuitry for measuring the duration of an outage of the AC energy quantity and for restoring the amount of lost realtime to the realtime clock of the microprocessor upon resumption of the AC energy quantity. The power outage recovery circuitry includes apparatus for iteratively updating the microprocessor realtime clock while comparing the updated realtime with the clock calendar times of the number of time-related events to account for the occurrence of such events during the outage of the AC energy quantity.
One of four inventors on this patent.
Approximately 50K units produced per year using this patent.

United States Patent: 4,633,220
Decoder using pass-transistor networks
A matrix comprised of pass transistor cells forms an address decoder circuit. By using pass transistor cells in a matrix format, a decoder which consumes a minimum of power and which may be constructed using a minimum of allotted space in an integrated circuit is achieved.
Only inventor on this patent.
Approximately 500K units produced per year using this patent.
