Patents by Inventor Jerry Doniger

Jerry Doniger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Multi-engine autothrottle providing automatic engine EPR equalization
    Patent number: 4410948
    Abstract: A throttle controller for a vehicle, such as an aircraft, having a plurality of engines (36-42). Each engine is regulated by a throttle. The controller includes a thrust sensor (44), a speed sensor (IAS), and an actuator (10). The thrust sensor (44) responds to the engines (36-42) to produce a plurality of thrust signals (22). These thrust signals correspond to the thrust produced by a different corresponding one of the engines. The speed sensor (IAS) can produce a speed signal corresponding to aircraft speed. The actuator (10) can adjust the throttle of each engine. The actuator is connected to the speed (IAS) and thrust sensors (44) and can respond to their signals to adjust each throttle and balance the thrust of the engines.

  • Controller for a dual servo system
    Patent number: 4370706
    Abstract: A controller (FIGS. 1, 2) is provided in a dual servo system that drives a controlled element (22) with mechanically coupled first and second servos (24 and 44). This controller has a first (10, 110, 112) and second (14, 108, 114) digital process subsystem. The first digital processing subsystem can simultaneously drive the first and second servos. This first processing subsystem is operable to measure the responsiveness of the servos to the first processing subsystem and provide a self-checking indication. The second digital processing subsystem measures the responsiveness of these servos to the first digital processing subsystem and can provide an independent indication of failure. The foregoing can be extended to multiple channels for controlling independent multiple elements such as aircraft control surfaces. Preferably, two different types of computers (10, 14; 108, 110, 112, 114) with different programs can be employed to control three control channels.

  • Digital flight guidance system
    Patent number: 4217486
    Abstract: A digital flight guidance system includes a pair of processors, each with its own memory means and arranged with common input and output means for providing monitored guidance of an aircraft when the craft is in cruise modes or when the craft is performing a critical maneuver such as landing, terrain following, or the like.
