Patent number: 8150057Abstract: Systems and methods for wireless communication can include a first unit configured to synchronously transmit a first digital audio packet redundantly in at least a first dedicated slot and a second dedicated slot over a time period, and a second unit configured to receive wireless transmissions from the first unit. In certain embodiments, the second unit does not listen for a transmission in the second dedicated slot if the first digital audio packet is received in the first dedicated slot. In certain embodiments, the units are encoded with a group code that identifies group members, such that the units only receive data packets transmitted by group members with the same group code.Type: GrantFiled: December 31, 2008Date of Patent: April 3, 2012Assignee: Etymotic Research, Inc.Inventor: William Frank Dunn

Patent number: 7555134Abstract: Wireless earphone systems provide earphones configured to be supported entirely by the ear canals of the wearer and to provide stereophonic reproduction of sound to the wearer based on a two-channel stereophonic signal from a transceiver that is attachable to a device. Certain systems include earphones configured such that channel reception can be switched between the earphones. Certain systems include an earphone that includes: a housing; a ground plane comprising circuitry; and a multi-segmented antenna configured to receive a signal from a transceiver, wherein the antenna and the ground plane are disposed within the housing, wherein the antenna is substantially parallel to the ground plane, and wherein the antenna and the ground plane are separated by a distance.Type: GrantFiled: August 31, 2007Date of Patent: June 30, 2009Assignee: Etymotic Research, Inc.Inventors: William Frank Dunn, Timothy Milam, Kelly Kodama, Mead Killion, Viorel Drambarean, David Michael Friesema

Patent number: 6581449Abstract: Method and apparatus (200) for monitoring vehicle tire pressure and warning the driver when a low tire inflation pressure condition occurs includes transponder tags (220a . . . 220d, 300, 300a) and associated sensors (e.g., pressure, temperature) for each tire and a monitor (230a . . . 230d, 400 disposed in close proximity to each tire (204a . . . 204d). In this case manner, a low-powered radio transmission can take place between each tire tag and an associated one of the monitors. Each monitor is connected to a vehicle data bus 206, 430) for communicating, preferably bi-directionally, with a computer (208), and a central display (212) provides visual (or audible) warnings to the operator of the vehicle. The system is simple in operation, economical to manufacture, easy to install, and highly reliable, and conforms to standards established for heavy vehicles, and can be used on passenger car applications as well.Type: GrantFiled: February 11, 2002Date of Patent: June 24, 2003Assignee: The Goodyear Tire & Rubber CompanyInventors: Robert Walter Brown, William Frank Dunn

Patent number: 6538569Abstract: A sealed container is provided with a sensor capable of monitoring the physical and/or chemical condition of materials stored in the container. The sensor may or may not have its own power source. In the embodiment where the sensor does not have a power source, a communicator induces a signal in the sensor and receives a return signal with the desired data. The container may be a metal or a nonmetal.Type: GrantFiled: March 1, 2001Date of Patent: March 25, 2003Assignee: The Goodyear Tire & Rubber CompanyInventor: William Frank Dunn

Patent number: 6139401Abstract: A method for correcting the balance of a pneumatic tire mounted in a tire uniformity machine modified for balance screening such tires. After balance screening of the tires, tires which are unacceptably imbalanced are maintained at the second rotational speed of the balance screening routine. A grinding wheel is brought to the position of maximum radial and/or lateral deflection causing tire material to be removed from deflected portions of the tire. The tire is once again balance checked and if the balance is still unacceptable, the grinder is advanced an incremental unit of distance toward the center of the tire, more tire material is removed, and the balance is again checked. The steps of advancing the grinder, removing material, and checking the tire imbalance are performed until the tire is found to have acceptable static and couple imbalance.Type: GrantFiled: October 28, 1998Date of Patent: October 31, 2000Assignee: The Goodyear Tire & Rubber CompanyInventors: William Frank Dunn, John Michael Maloney, George Jeffrey Lipczynski

Patent number: 5703680Abstract: When the pressure on a reinforced rubber object is varied, weaker portions of the object expand more than surrounding areas of the object. By (a) illuminating the object with single phase monochromatic light which is separated into more than one beam, (b) causing the object to distort by abrasion or expansion, (c) observing the interference patterns on the object as it distorts and (d) analyzing stress patterns revealed by the interference patterns, these physical changes can be detected, recorded and analyzed.Type: GrantFiled: January 16, 1996Date of Patent: December 30, 1997Assignee: The Goodyear Tire & Rubber CompanyInventors: William Frank Dunn, John Michael Maloney, Michael Lynn Hooper, Wayne David Maas

Patent number: 5638732Abstract: An apparatus for cutting an elongated body of elastomeric material includes a tensioned wire which is oscillated in a generally up and down motion while traversing through the elastomeric material. The wire acts as a cutting blade and prepares the cut surface of the elastomeric material to improve splices. The wire is suspended between a pair of pivotally mounted arms so that the wire oscillates as the arms are rocked by an eccentric mounted to a rotating shaft. The cutter wire passes through the body of elastomeric material at an angle relative to the plane in which the body of elastomeric material lies. The body of elastomeric material is secured in place by clamp segments which conform themselves to the cross-sectional shape of the body. The cutter wire is traversed through the elastomeric material on a cutter frame which is moved by a ball screw driven by a variable speed electric motor.Type: GrantFiled: September 2, 1994Date of Patent: June 17, 1997Assignee: The Goodyear Tire & Rubber CompanyInventors: Michael Lee Becker, Klaus Beer, Daniel Ray Downing, William Frank Dunn, James Michael Hart, Dennis Alan Lundell
