Publication number: 20100308664Abstract: A self-powered switching system using electromechanical generators generates power for activation of a latching relay, switch, solenoid or latch pin. The electromechanical generators comprise electroactive elements that may be mechanically actuated to generate electrical power. The associated signal generation circuitry may be coupled to a transmitter for sending RF signals to a receiver which actuates the latching relay. The use of mechanically activated membrane switches on the deflector or on a keypad allows multiple code sequences to be generated for activating electrical appliances. The system also uses a communications protocol allowing the receivers to respond to signals from transmitters and/or repeaters. The use of one or more repeaters also increases the reliability of the system as well as extending its effective transmission range.Type: ApplicationFiled: May 22, 2009Publication date: December 9, 2010Inventors: Bradbury R. Face, Glenn F. Rogers, JR.

Patent number: 6780369Abstract: A method of finishing concrete using a vibrating tool to consolidate a “dry shake” aggregate into the upper layer of the concrete. The use of the vibrating tool causes moisture within the concrete mass to migrate into the surface layer where the moisture may hydrate the aggregates in the dry shake mixture. The ability to cause upward migration of water in the concrete mass provides a larger window of finishability for the concrete. The vibrations also provide thorough consolidation of aggregates in the upper layer of the concrete mass helping to prevent delamination.Type: GrantFiled: August 2, 1999Date of Patent: August 24, 2004Assignee: Face International Corp.Inventors: Darrell Darrow, Glenn F. Rogers, Jr., Samuel A. Face, Jr., David Francis, Michael Davis, Yuting Wang

Patent number: 6392329Abstract: A piezoelectrically actuated vibratory motor comprises actuators that are mounted “vertically” with their edges attached to top and bottom mounting members. An oscillating voltage applied to the actuators causes them to contract and expand to move the attached mounting members in a direction essentially parallel to the faces of the actuators. The force transmitted to the mounting members at the edges of actuators is greater than the typical force taken at the center of a face of the actuator.Type: GrantFiled: October 12, 1999Date of Patent: May 21, 2002Assignee: Face International Corp.Inventors: Timothy D. Bryant, Glenn F. Rogers, Jr., Samuel A. Face, Jr.

Patent number: 6101880Abstract: A method is disclosed for advantageously modifying the texture or character of a plastic work material by applying acoustic energy at the work material's natural resonant frequency via a transducer assembly including vibrating the transducer assembly in air to determine the natural resonant frequency of the transducer assembly; determining the natural resonant frequency of the work material and the transducer assembly together; subtracting the natural resonant frequency of the transducer assembly from the natural resonant frequency of the work material and the transducer assembly together to determine the natural frequency of the work material; and applying acoustic energy to the work material at the determined natural frequency of the work material. The transducer assembly includes piezoelectric actuators which provide the acoustic energy.Type: GrantFiled: March 25, 1998Date of Patent: August 15, 2000Assignee: Face International Corp.Inventors: Samuel A Face, Jr., Glenn F. Rogers, Richard P. Bishop

Patent number: 6013972Abstract: A vibrating mechanism comprised of piezoelectric elements which vibrate at a high frequency when a voltage is applied to them. The piezoelectric elements are mounted on a rib so that their free ends extend from the rib. When the piezoelectric elements are energized the free ends vibrate with a "wing-flapping" motion. Weights may be attached to the free ends of the piezoelectric element to increase the inertial component of vibration. In the preferred embodiment of the invention, the piezoelectric elements are prestressed. The invention will be an inexpensive substitute for other vibratory devices.Type: GrantFiled: October 15, 1997Date of Patent: January 11, 2000Inventors: Samuel A Face, Jr., Glenn F. Rogers, Jr., Richard P. Bishop

Patent number: 5837298Abstract: A vibrating hand trowel for finishing plastic concrete. The vibratory mechanism includes piezoelectric elements which vibrate at a high frequency when a voltage is applied to them. The trowel as a whole includes a top piece including a cover plate and handle, and a bottom piece including the piezoelectric elements mounted on a rib and a flat bottom which contacts the concrete. The top and bottom piece are preferably attached by a series of screws. The vibrating trowel is pulled over the concrete creating a smooth, wet layer useful for lubrication of the area where the trowel and concrete are in contact. This layer develops because the vibrations cause water and air to rise to the top of the concrete. The invention will allow for easy finishing of plastic concrete because of its lightweight and simple design. The invention will also create a smooth finish of the hardened concrete.Type: GrantFiled: October 15, 1997Date of Patent: November 17, 1998Assignee: Face International Corp.Inventors: Samuel A. Face, Jr., Glenn F. Rogers, Jr., Richard P. Bishop

Patent number: 5814232Abstract: Vibrational energy is introduced into a portion of a liquid-solid work mixture at a natural resonant frequency of that portion of the mixture while that portion of the mixture is in a fluid or semi-fluid state. A vibrating apparatus imparts controlled vibrations either onto the surface or beneath the surface of the liquid-solid work mixture in sequential stages, the frequency of vibrations generally increasing with each subsequent stage, corresponding to an increase in the natural resonant frequency of the progressively-narrowing liquid portion at the top of the liquid-solid work mixture. A resonant frequency-indicative condition of the liquid portion of the work mixture adjacent the vibrator apparatus is sensed as the vibrator apparatus moves across the top surface of the liquid-solid mixture, and the output frequency of the vibrating apparatus is correspondingly adjusted in accordance with the sensed condition as the vibrator apparatus travels.Type: GrantFiled: March 5, 1996Date of Patent: September 29, 1998Inventors: Samuel A. Face, Jr., Glenn F. Rogers, Jr., Richard P. Bishop, Darrell L. Darrow, Brad Face

Patent number: 5527175Abstract: Vibrational energy introduced into plastic concrete structures, such as concrete slabs, decks and similar or related concrete structures, at or near the natural resonant frequency of the liquid concrete mass, expedites the consolidation and setting of the concrete. A vibrating apparatus imparts controlled vibrations either onto the surface or beneath the surface of the concrete mass in sequential stages, the frequency of vibrations generally increasing with each subsequent stage, corresponding to the increase in the natural resonant frequency of the progressively-narrowing liquid concrete at the top of the structure. The relatively more consolidated and more dry concrete (typically near the bottom of the slab) is substantially unaffected by the non-resonant frequencies vibrations. In one modification, sensors determine the resonant frequency of the liquid concrete mass during each pass of the vibrator apparatus, and the frequency of the vibrating member is automatically adjusted, accordingly.Type: GrantFiled: December 3, 1993Date of Patent: June 18, 1996Inventors: Samuel A. Face, Jr., Bradbury R. Face, Glenn F. Rogers, Jr., Darrell Darrow, Richard P. Bishop
