Patent number: 7487854Abstract: A two-wheel drive motorcycle having a drive train that supplies power to the front wheel and includes a series of rigid shafts or other internalized drive systems. The front wheel drive consists of components located on the axis of steering within the head tube and positioned symmetrically in a counterbalancing fashion within the front fork in order to counteract the torque reactions from the rotating front wheel drive while providing a full range of steering. The front wheel drive lengthens and shortens in parallel with the shock-absorbing front fork. An engagement clutch, a one-way hub, and torque limiting clutch operatively engaged with the front wheel drive are also disclosed.Type: GrantFiled: January 3, 2008Date of Patent: February 10, 2009Assignee: Christini Technologies, Inc.Inventors: Steven J. Christini, Michael J. Dunn, Louis J. Allora, Robert Pigeon, Jeremy T. Shook

Publication number: 20080200767Abstract: A surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter, the retractor includes a first ring having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound. A second ring has a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound. A plurality of retraction elements are disposed in a generally cylindrical relationship to each other, between the first ring and the second ring. These elements extend through the wound to exert a radial retraction force on the wound which is dependent on the distance separating the first ring and the second ring. Retraction elements, both distensible and non-distensible are contemplated with appropriate attachment means at the rings to provide for variations in the retraction force. With a suitable retraction sleeve, a third ring can be provided to form a circumferential retainer to vary the retraction force.Type: ApplicationFiled: April 23, 2008Publication date: August 21, 2008Applicant: APPLIED MEDICAL RESOURCES CORPORATIONInventors: Richard C.

Patent number: 6463570Abstract: An apparatus and method for verifying a process step in the fabrication of an integrated circuit device is implemented. A ring oscillator is fabricated on the dice constituting the integrated circuit device being manufactured. The ring oscillator structure is adapted for sensitizing the ring oscillator to variations in the process step being verified. During test of the wafer containing the dice, a scan of the frequency of the ring oscillator across the wafer for each die under test is made. Deviations in the ring oscillator frequency from a preselected nominal value delimit regions of the wafer for which the process step is marginal.Type: GrantFiled: July 26, 2000Date of Patent: October 8, 2002Assignee: Advanced Micro DevicesInventors: Michael J.

Patent number: 5600706Abstract: A position system and method utilizes a plurality of range transceivers located at known fixed locations and which are adapted to transmit approximately synchronized digital range signals for receipt by both a primary receiver and a supplemental receiver, the former disposed at a known location and the latter disposed at an unknown location. The range transceivers are adapted to transmit pulse sequences which include an error portion corresponding to the approximate synchronization error of each range signal. This error portion is constantly updated in accordance with the last determined synchronization errors of the corresponding range signals received by a secondary transceiver. In an alternative embodiment employing Code Division Multiple Access (CDMA) technology, the range transceiver time stamp on transmitted range signals may be adjusted to account for the measured timing error for a given range transceiver.Type: GrantFiled: May 9, 1994Date of Patent: February 4, 1997Assignee: U S West, Inc.Inventors: Michael J.

Patent number: 5322644Abstract: A process for decontaminating radioactive material comprises the step of contacting the material with a dissolving composition to dissolve the contaminants in the material, said composition comprising a dilute solution of about 0.05 molar ethylene diamine tetraacetic acid, about 0.1 molar carbonate, about 10 grams per liter hydrogen peroxide and an effective amount of sodium hydroxide to adjust the pH of the composition to a pH from about 9 to about 11. Also included are the steps of separating the dissolving composition containing the dissolved contaminants from the contacted material and recovering dissolved contaminants from the dissolving composition that has been separated from the material. A composition for dissolving radioactive contaminants in a material, comprising a dilute solution having a basic pH and effective amounts of a chelating agent and a carbonate sufficient to dissolve radioactive contaminants is also provided.Type: GrantFiled: January 3, 1992Date of Patent: June 21, 1994Assignee: Bradtec-US, Inc.Inventors: Michael J.

Patent number: 5295180Abstract: A system for marking a plurality of zones within a cellular service area. One or more marker transmitters are disposed throughout a cellular area to transmit a zone identification signal that is independent of normal RF cellular coverage to a mobile or portable cellular receiver. Each zone identification signal is transmitted in a radio frequency coverage area that illuminates the zone to be identified and is constrained by a similar transmitter jamming the zone signal. The marker transmitters are programmed to transmit the zone identification signal during a predefined time slot so that more than one marker transmitter may simultaneously transmit the zone identification signal, thereby increasing the area in which the zone identification signal can be received by the mobile unit. In order to reduce the area in which a zone identification signal may be received by a mobile unit, the marker transmitters may transmit a jamming signal at the same time as the zone identification signal is transmitted.Type: GrantFiled: April 8, 1992Date of Patent: March 15, 1994Assignee: U S West NewVector Group, Inc.Inventors: Dino J. Vendetti, Don H. Atherly, Ching Chuang, Elliott H. Drucker, Michael J. Dunn, Ronald E. Foerster, David G. Schoenmaker
