Patent number: 7328571Abstract: In accordance with a first aspect of the present invention, an aircraft having a scramjet engine is provided. The scramjet engine includes a flowpath which varies in three dimensions. In accordance with a second aspect of the present invention, a method for launching an aircraft having a scramjet engine with a nozzle section and a solid rocket booster positioned within the nozzle section is provided. The method includes the steps of igniting the solid rocket booster to accelerate the aircraft to a speed at which the scramjet engine can operate, clearing the nozzle section by ejecting the solid rocket booster from the nozzle section upon exhaustion of the solid rocket booster; and injecting fuel into a flow of air passing through the scramjet engine and igniting the fuel and the air to provide thrust to the aircraft.Type: GrantFiled: November 29, 2004Date of Patent: February 12, 2008Assignee: United Technologies CorporationInventors: Alan Drake, Daniel Guinan

Publication number: 20080024233Abstract: An inverting circuit comprises a first inverter in a main path having a first input and a common ouput. A second inverter receives the first input and is coupled with a first voltage controlled pass gate to the common output. A third inverter couples a second input to the common output using a second voltage controlled pass gate. A fourth inverter couples the second input to the common output using the first voltage controlled pass gate. A ring oscillator is formed using a number N of the inverting circuits with each common output coupled to the first inputs forming a main ring of a ring oscillator. The second inputs are coupled to feed-forward signals from selected outputs. The resulting signals at the common outputs are an interpolation of the first and second input signals modulated by a control voltage coupled to the first and second pass gates.Type: ApplicationFiled: September 4, 2007Publication date: January 31, 2008Applicant: International Business Machines CorporationInventors: Alan Drake, Fadi Gebara, Jeremy Schaub

Publication number: 20070168786Abstract: A scanned value is stored by loading the value into at least three latch stages, generating an output value based on a majority of the latch stage outputs, and feeding the output value back to the inputs of the latch stages to reload the latch stages with the latch circuit output value. Refreshing of the latch stages in this manner repairs any upset latch stage and restores the latch circuit to its original scanned state. The latch circuit may be repeatedly refreshed, preferably on a periodic basis, to prevent failures arising from multiple upsets. The feedback path may include a front-end multiplexer which receives the scan-in line and the output of the majority gate. Control logic selects the output value from the majority gate to pass to the latch stages during the refresh phase. The latch stages may be arranged in a master-slave configuration with a check stage at the slave level. The method is particularly suited for self-correcting scan latches of a microprocessor control system.Type: ApplicationFiled: July 28, 2005Publication date: July 19, 2007Inventors: Alan Drake, Aj Osowski, Andrew Martin

Publication number: 20070028157Abstract: A latch circuit having three latch stages generates a majority output value from the stages, senses when the latch stage outputs are not all equal, and feeds the majority output value back to inputs of the latch stages to reload the latch stages. The latch circuit uses a not-equal gate whose output is an error signal that can be monitored to determine when a single-event upset has occurred. A master stage is controlled by a first multiplexer which receives one system clock signal, while a slave stage is controlled by a second multiplexer which receives another system clock signal, and the latch stage outputs are connected to respective inputs of the not-equal gate, whose output is connected to second inputs of the multiplexers. The latch circuit is part of a latch control system, and reloading of the latch stages takes less than one cycle of the system clock (less than 500 picoseconds).Type: ApplicationFiled: October 3, 2005Publication date: February 1, 2007Inventors: Alan Drake, Aj KleinOsowski, Andrew Martin

Publication number: 20060103441Abstract: A circuit and method of correcting the duty cycle of digital signals is disclosed. The duty cycle of an input digital signal is measured and compared to a desired duty cycle. The leading edge of the input digital signal is passed to an output. The circuit and method adjust the falling edges at the output to achieve the desired duty cycle. The falling edges occur in response to rising edges of a delayed version of the input digital signal.Type: ApplicationFiled: November 12, 2004Publication date: May 18, 2006Applicant: International Business Machines CorporationInventors: Gary Carpenter, Alan Drake, Fadi Gebara, Chandler McDowell, Hung Ngo
