Publication number: 20060084902Abstract: A suspension system for the care and prevention of wounds on the body of a user includes an array of removable suspension devices forming a flexible sheet. Each suspension device is removably coupled to at least on other suspension device. The suspension devices are selectably removable from the array in order to define a space within the sheet which approximates the size of a target area on the body of the user. A disposable garment for the body of a user includes an absorbent portion and a wound are and prevention suspension portion. The absorbent portion has fluid pervious inner sheet, a fluid impervious outer sheet and at least one layer of absorbent material disposed between the inner and outer sheets. The wound are and prevention suspension portion is coupled to the absorbent portion.Type: ApplicationFiled: December 6, 2005Publication date: April 20, 2006Inventors: Thomas Schleicher, R.

Publication number: 20050184758Abstract: An integrated circuit includes first circuitry and sleep transistor circuitry. The first circuitry receives input signals and processes the input signals. The first circuitry also retains data in a sleep state that has low leakage. The sleep transistor circuitry is coupled to the first circuitry and receives a sleep signal that has a negative voltage. The sleep circuitry reduces power consumption of the first circuitry in the sleep state to have low leakage based on the sleep signal while retaining the data in the first circuitry.Type: ApplicationFiled: January 20, 2005Publication date: August 25, 2005Inventors: Barry Hoberman, Daniel Hillman, William Walker, John Callahan, Michael Zampaglione, Andrew Cole

Publication number: 20050177855Abstract: Methods and apparatus for performing dynamic compensation for delays over extant infrastructure within a content-based network. In one embodiment, the network comprises a cable network, and the infrastructure comprises that nominally used for on-demand (OD) services such as VOD. The method includes periodically or situationally assessing variable delays within the system associated with functional commands (such as “trick mode” commands), and dynamically compensating for these variable delays in order to improve the accuracy and timeliness of the user's trick mode command. This approach increases user satisfaction, and obviates the issuance of additional compensatory trick mode commands that only further degrade the performance of the network.Type: ApplicationFiled: February 11, 2005Publication date: August 11, 2005Inventors: Stephen Maynard, Tho Autruong, John Callahan, Nicholas Nielsen

Publication number: 20050055685Abstract: A resident application (RA) in set-top terminals (STTs) is updated by providing an upgrade channel application (UCA) over a network. Those STTs that are selected to receive the UCA are identified. The selected STTs download the UCA from the network. Once the UCA begins to execute on an STT, it retrieves the user parameters stored in the STT, and transmits them to a remote location for storage. A new RA is then installed in the STT. The original user parameters are converted at the remote location to become compatible with the new RA. The converted user parameters are transferred to the STT for use by the new RA.Type: ApplicationFiled: September 5, 2003Publication date: March 10, 2005Inventors: Stephen Maynard, Jed Reed, John Callahan, Benjamin Payne

Patent number: 5604694Abstract: An improved charge pump circuit uses standard low-voltage fabrication process for programming an anti-fuse memory cell from a high-voltage current source. A column-selection transistor which has a gate terminal connected to a control terminal. The column-select transistor is connected between a high voltage programming current source and one terminal of an anti-fuse link. The other terminal of the anti-fuse link is connected through a word-selection transistor to ground. The gate terminal of the word-selection transistor is connected to a word selection line. Two oppositely phased charge pumps provide a boosted voltage. A trapping-diode-connected transistor isolates the boosted voltage from the gate terminal of the column-selection transistor. A charge-kicker circuit further boosts the voltage on the gate of the column-selection transistor to turn on and pass current from the high voltage programming current source through the anti-fuse link.Type: GrantFiled: January 16, 1996Date of Patent: February 18, 1997Assignee: VLSI Technology, Inc.Inventor: John Callahan

Patent number: 5465009Abstract: Novel processes and apparatus permit lift-off, alignment, and bonding of materials and devices. The processes involve first depositing a device layer on a sacrifical layer situated on a growth substrate. A device may be defined in the device layer. The device layer or the device is coated with a carrier layer. The sacrificial layer and/or the growth substrate are then etched away to release the combination of the device layer and the carrier layer from the growth substrate. The device layer or device can then be aligned and selectively bonded to a host substrate. Other processes and apparatus are set forth for facilitating lift-off, bonding, handling, and patterning of he device layer or device.Type: GrantFiled: February 15, 1994Date of Patent: November 7, 1995Assignee: Georgia Tech Research CorporationInventors: Timothy J. Drabik, Kevin P. Martin, John Callahan

Patent number: 4242575Abstract: Price encoder for delivering pulses corresponding to the price of gasoline or other liquid petroleum products dispensed by a pump. The encoder is removably mounted on the existing mechanical price computer in the pump and includes an input gear for engaging a drive gear on the computer. A pulse generator coupled to the input gear provides pulses at a higher rate than required for the output, and this pulse rate is reduced by a counter to provide a desired number of pulses per unit price. The counter is reset in response to the application of operating power to eliminate errors which might otherwise arise when the pump is reset.Type: GrantFiled: February 7, 1978Date of Patent: December 30, 1980Assignee: RF Products Corp.Inventors: John A. Callahan, Allan S. Ottenstein

Patent number: 4109777Abstract: A ticket printer is disclosed. A motor equipped with a centrifical speed governor, opposing ticket rollers and ticket transport tray rolls a blank, multipage ticket form past seven needle printing heads which are solenoid actuated and two sequencing switches. The ticket to be printed is inserted into the ticket transport tray and engages a motor operate switch which rotates certain ticket rollers at a governed speed. The ticket advances, pinched by opposing rollers and moves beneath the seven parallel needle printing heads and also actuates a print start switch which initiates electronic operation. The ticket continues its advance while being printed for N digits until the ticket disengages the motor start switch whereupon the drive motor rotates sufficiently to expel the ticket from the tray and printer. The apparatus accepts N digits of BCD formated data in serial fashion.Type: GrantFiled: August 2, 1976Date of Patent: August 29, 1978Assignee: Research Fuels, Inc.Inventors: Allan S.
