Patent number: 8070455Abstract: A primary scotch yoke and a secondary scotch yoke are coupled in opposing arrangement and rigidly attached to a linearly reciprocating element. Each scotch yoke includes a rotary actuator with a cam follower and a yoke attached to the reciprocating element. Each yoke has a cam with an open gap through which the follower may be disengaged from the cam and stopped to an idle position. The follower of the secondary scotch yoke is kept idle in a position similarly disengaged from its cam. A controller detects a failure in the primary scotch yoke, disengages the cam follower of the primary yoke from its cam, and energizes the secondary scotch yoke, thereby causing its cam follower to engage its yoke and continue to provide uninterrupted motion to the reciprocating element, in particular the portable pneumatic pump driving an artificial heart.Type: GrantFiled: July 7, 2009Date of Patent: December 6, 2011Assignee: Syngardia Systems, Inc,.Inventor: Frank A. Tinker

Patent number: 8021422Abstract: A pneumatic pump comprises two coaxial cylindrical pumping chambers, each enclosing a piston connected to the other through a partition by a tube, thereby forming a monolithic piston assembly that is driven axially by a common electrical actuator providing reciprocating motion. The volume in the bottom chamber is selected as needed to provide the desired pressure in the left ventricle of an artificial heart driven by the pump. The diameter of the tube connecting the pistons is selected such that the stroke volume of the top chamber is reduced with respect to that of the bottom chamber as needed to match the reduced pressure requirements of the right ventricle of the artificial heart. Check valves are used in each chamber to ensure venting of excess pressure during the blood ejection phase and to limit the vacuum during the fill phase.Type: GrantFiled: May 18, 2009Date of Patent: September 20, 2011Assignee: Syncardia Systems, Inc.Inventor: Frank A.

Patent number: 7801830Abstract: The present invention relates to systems and methods for intellectual property marketing, management, and maintenance. An intellectual property marketing system manages the marketing of an intellectual property asset, where the intellectual property asset is based at least in part on an innovation submission of an innovator. An innovation maintenance management system manages rewarding of the innovator based at least in part on the innovation submission.Type: GrantFiled: December 29, 2000Date of Patent: September 21, 2010Assignee: AT&T Intellectual Property I, L.P.Inventors: Scott M.

Patent number: 7610894Abstract: The efficiency of a multi-cylinder engine is optimized by coupling the volume change in each cylinder to a common coordinate under conditions such that, at each point in the engine's cycle, the energy necessary to produce a differential volume change is reduced substantially to zero. Each cylinder is coupled to the common coordinate through a cam or through a variable-length connecting rod. The same efficiency optimization may be achieved with various combinations of cylinders in a two-cycle engine, a four-cycle engine, or a multi-cylinder compressor.Type: GrantFiled: May 25, 2007Date of Patent: November 3, 2009Assignee: FSNC, LLCInventor: Frank A.

Patent number: 7454883Abstract: A device for removing a closure from a container includes a hollow needle, a piston for driving the needle into the closure and a compressed gas cartridge for driving the piston. Once the needle has been driven into the closure so that an end of the needle is inside the container, the piston can reciprocate to force air through the needle and pressurize the container in order to eject the closure. The piston can also reciprocate to evacuate air from the container through a stopper with a check valve when leftover contents of the container are to be preserved.Type: GrantFiled: August 15, 2006Date of Patent: November 25, 2008Inventors: Robert Q. Hoyt, Frank Tinker

Patent number: 7441530Abstract: A conservative force coupled to the piston of a reciprocating-piston engine, refrigerator, or compressor acts to counter the pressure force on the piston that arises from the change of volume of the working substance accompanying a change in the piston position. As a result, the efficiency of the engine, refrigerator, or compressor is improved to approach the theoretical thermodynamic limit of the underlying process.Type: GrantFiled: May 16, 2005Date of Patent: October 28, 2008Assignee: FSNC, LLCInventor: Frank A.

Patent number: 6954423Abstract: Analog phase-shift elements connect each of a plurality of input nodes to each of a plurality of output nodes, wherein each component is adapted to produce a phase shift in a periodic signal processed therethrough. A linear transformation of a data set of discrete values of a given function provided as a set of analog signals to the input nodes is achieved by judiciously adjusting the signal amplitude produced at the output of the phase-shift components and summing the resulting output signals as required to simulate the transformation of interest.Type: GrantFiled: January 21, 2003Date of Patent: October 11, 2005Inventor: Frank A.

Patent number: 6386390Abstract: A dispenser has a container for a liquid, a vent opening to allow air into the container, a valve to control the admission of air into the container, and a dispensing opening for the liquid to be dispensed therefrom. The dispenser is mounted with the dispensing opening at the bottom. When the valve is closed, a pressure differential is created that prevents the liquid in the container from flowing out. Upon opening of the vent valve, the pressure differential is reduced and dispensing can continue. Such a dispenser can be used to dispense fluids of varying viscosities and even nonporous solids. In one embodiment of the invention, an infrared radiation emitter and an infrared radiation detector are arranged in such a manner that, when a hand is placed below the dispenser, radiation from the emitter impinges on the hand and is reflected to the detector.Type: GrantFiled: December 1, 1999Date of Patent: May 14, 2002Inventor: Frank A.
