Patent number: 8664816Abstract: A permanent magnet is rotated about an axis extending between opposing north and south poles. The magnetic field of the rotated permanent magnet interacts with magnetic fields of permanent magnets carried by a shuttle for repelling and attracting the fixed permanent magnets, and providing a linear reciprocating movement of the shuttle responsive to the favorable rotary motion of the rotated permanent magnet where the force of the linear motion is captured by an energy storage device.Type: GrantFiled: March 15, 2013Date of Patent: March 4, 2014Assignee: Magnamotor, LLCInventors: John W. Edwards, Robert M. Herrin, Johnny M. Tharpe, Jr.

Patent number: 8336409Abstract: A magnetic piston includes a housing having a tapered bore extending along an axis thereof and a piston having a tapered outside wall mating with the tapered bore of the housing for providing radial and longitudinal movement within the tapered bore about a rotational axis of the piston. A shaft is connected to the piston for movement along its longitudinal axis thereof, wherein the axes of the tapered bore and piston are generally aligned along the longitudinal axis. A first set of magnets is embedded within the outside wall of the piston and a second set of magnets is embedded within a surface of a wall forming the bore of the housing. The polarity for each of the magnets within the sets provides attracting and repelling forces causing rotation of the piston relative to the housing and a linear movement of the shaft along the longitudinal axis.Type: GrantFiled: December 10, 2009Date of Patent: December 25, 2012Assignee: Magnamotor, LLCInventor: John W.

Patent number: 6766479Abstract: Disclosed is a novel structure and process for detecting protocol errors on a communications bus. According to one aspect of the invention, a protocol error detector comprises a physical error detector, a sequential error detector, and a logical error detector, each detecting physical, sequential, and logical protocol violations, respectively, and signaling a bus transaction error when a protocol violation is detected. In one embodiment, the protocol error detector substantially simultaneously checks each bus transaction for physical, sequential, and logical protocol violations. In another embodiment, the protocol error detector signals a detected bus transaction protocol violation substantially coincident with the bus transaction.Type: GrantFiled: February 28, 2001Date of Patent: July 20, 2004Assignee: Stratus Technologies Bermuda, Ltd.Inventor: John W.
