Patent number: 7703848Abstract: The invention includes a vehicle simulator for simulating the sounds and vibrations generated by a moving vehicle. The vehicle simulator includes a housing configured to receive any standard infant carrier including infant vehicle seats. An acoustic system, including an acoustic output transducer and a control unit, is coupled to the housing. The control unit provides a drive signal to the acoustic transducer, which the acoustic output transducer converts into sound waves that provide both vehicle movement sounds and vehicle movement vibrations. When an infant carrier in which an infant is seated is received within the housing, the vehicle movement sounds and vibrations are transmitted by the acoustic output transducer to the infant carrier where the sounds and vibrations create a soothing environment of sound and vibration designed to mimic the environment inside a moving vehicle.Type: GrantFiled: October 16, 2006Date of Patent: April 27, 2010Inventors: David B. Cochran, Bryce R. Hein, Michael Kung, Susannah A. Scholl, Gregory A. Tacchetti

Patent number: 6789767Abstract: An active satellite dispenser is preferably attachable to a reusable launch vehicle for deployment of one or more satellites into one or more desired orbits. The active satellite dispenser includes a center mast that releasably receives the satellite(s), a liquid propellant rocket, and an orbital control system on an avionics pallet. In the preferred embodiment, a pressurized gas selectively pressurizes the propellant tanks (which may include fuel and oxidizer tanks), to provide propellant to the rocket. In operation, the launch vehicle releases the satellite dispenser in a first deployment orbit. The active dispenser rocket and orbital control system then transport the active dispenser and satellite(s) into the final deployment orbit. In the preferred embodiment the active dispenser can operate multiple times to place individual satellites in different orbits.Type: GrantFiled: April 23, 2002Date of Patent: September 14, 2004Assignee: Kistler Aerospace CorporationInventors: George E.

Patent number: 6513760Abstract: An orbital vehicle (34) having a propulsion module (33) and a logistics module (36). The logistics module includes a generally cylindrical outer shell (56, 541, 542) with first and second ends. An openable cover (58) is coupled with the outer shell at the first end, thereby providing access to the interior of the logistics module. The second end is adapted to couple to the propulsion module. A cargo container (54) is disposed generally within the outer shell, the cargo container including a berthing mechanism (70) disposed to be accessible when the cover is opened. A retractable grapple fixture (176) is provided on the logistics module, selectively positionable between an extended position and a retracted position. When the grapple fixture is in the extended position a grapple shaft (78) can be accessed to secure the orbital vehicle. When the grapple fixture is retracted, it is enclosed within the orbital vehicle.Type: GrantFiled: December 11, 2000Date of Patent: February 4, 2003Assignee: Kistler Aerospace CorporationInventors: George E.

Patent number: 6082676Abstract: An aluminum cryogenic tank for launch vehicles has aluminum skirts that extend from each end of a peripheral wall of a tank body. The skirts provide a temperature differential between the tank body and the ends of the skirts so that composite panels can be used in locations longitudinally proximate to the tank body without over stressing either the skirts or the composite panels in regions near their junctures and without sacrificing structural integrity of the composite panels due to an excessively low temperature. The peripheral wall of the tank and the skirts provide a portion of a structural/aerodynamic wall or shell of the launch vehicle.Type: GrantFiled: February 25, 1998Date of Patent: July 4, 2000Assignee: Kistler Aerospace CorporationInventor: David B.

Patent number: 5298799Abstract: The provision of a clock chopper, pulse shaper, single-shot circuit with NOR gates a delay path and a set-reset latch. In response to a high input (for example) to a first NOR gate, the circuit output goes high and remains high until the output of the one NOR gate propagates through the delay one input of a second NOR gate whose other input is coupled to a set-reset latch. When the delayed output of the first NOR gate reaches the input of the second NOR gate, the circuit output falls, and the change in circuit output is fed back to reset the latch. The change in latch state changes the output state of the second NOR gate and resets the circuit for next input.Type: GrantFiled: December 31, 1992Date of Patent: March 29, 1994Assignee: International Business Machines CorporationInventors: David B. Cochran, Kathleen M. Owczarski

Patent number: 5262690Abstract: A high-speed clock delay circuit in which an external differential digital clock signal is connected to a pair of differentially connected, current switching transistors. Emitter follower drivers couple the switching transistors to differential delayed clock output terminals. A pair of diodes cross-coupled between the differential output terminals and the switching transistors provide a relatively large Miller Effect capacitance, the charging and discharging of which provides a delay in the switching of the transistor pair, as measured differentially. Changing the charging and discharging current through the emitter follower driver, changes the bias across the diodes and thus changes their effective capacitance.Type: GrantFiled: April 29, 1992Date of Patent: November 16, 1993Assignee: International Business Machines CorporationInventors: David B. Cochran, Michael C. Lee, Kathleen M. Owczarski

Patent number: 5020027Abstract: A memory cell responsive to a write enable signal for storing write signals present on a pair of write bit lines and responsive to a read enable signal for presenting stored data on a pair of read sense lines further includes a timed, active write load. The memory cell includes first and second NPN bipolar transistors having commonly connected emitters, and cross-coupled bases and collectors; and first and second PNP bipolar transistors configured as loads for the pair of NPN bipolar transistors. Write transistors are provided responsive to the write enable signal for draining current from a selected one of the first or second nodes. Transistors connected as diodes between the respective PNP bases and each of the cross-coupled NPN nodes are responsive to the current draining effected by the write transistors for biasing a selected one of the first or second PNP transistors into an active mode of operation.Type: GrantFiled: April 6, 1990Date of Patent: May 28, 1991Assignee: International Business Machines CorporationInventor: David B.
