The revolutionary and yet simple design of the Ettridge Carbon Brush Commutator uses proven low carbon brush technology to achieve the same results as an electronic controller for a Stepper or Synchronized electric motor or generator.

Home automation is building automation for a home, called a smart home. A home automation system will monitor or control home attributes such as lighting, climate, entertainment systems, and appliances. It may also include home security such as access control and alarm systems.

In recent years, aluminum alloys have become the dominant material for body-in-white (BiW) and battery enclosures (“BE”) in electric vehicles (“EV”) due to their low density. Aluminum BiW and BE, or other platform parts, typically provide weight savings of ~40% compared to equivalent commercially-used steels.

High-Occupancy Vehicle (HOV) Systems

Our design idea solves the problems of cheating in High-Occupancy Vehicle (HOV) carpool lanes. HOV is a traffic management strategy experiencing a large, planned expansion. HOVs are used globally to reduce traffic congestion and promote public transportation use for encouraging ride-sharing.

The NerraTrac continuously variable transmission (CVT) utilizes a traction drive in a traction fluid (high viscosity lubricant) that ‘solidifies’ momentarily between two hardened metal surfaces under high contact pressure, thus providing a traction force. It employs the same elasto-hydrodynamic lubrication principle used by all current automotive CVT transmissions.
