Patent number: 10174679Abstract: A method of controlling a startup sequence of a gas turbine. A turbine of the gas turbine may include a rotor that has a rotor velocity and a rotor acceleration during the startup sequence. The method may include the steps of: determining an originally scheduled startup duration for the gas turbine; measuring an intermediate rotor velocity at an intermediate time within the startup sequence; determining a recalculated remaining startup duration that is a duration calculated as necessary to achieve the final rotor velocity given the intermediate rotor velocity; determining a remaining portion of the originally scheduled startup duration based on the intermediate time; calculating a time multiplier based on a comparison of the recalculated remaining startup duration to the remaining portion of the originally scheduled startup duration; and scaling the rotor acceleration per the time multiplier for a duration until the final rotor velocity is achieved by the turbine.Type: GrantFiled: March 10, 2017Date of Patent: January 8, 2019Assignee: General Electric CompanyInventors: Mathew Doyle Angel, Michael John Carney

Patent number: 8904393Abstract: Provided are techniques for increasing transaction processing throughput. A transaction item with a message identifier and a session identifier is obtained. The transaction item is added to an earliest aggregated transaction in a list of aggregated transactions in which no other transaction item as the same session identifier. A first aggregated transaction in the list of aggregated transactions that has met execution criteria is executed. In response to determining that the aggregated transaction is not committing, the aggregated transaction is broken up into multiple smaller aggregated transactions and a target size of each aggregated transaction is adjusted based on measurements of system throughput.Type: GrantFiled: September 11, 2012Date of Patent: December 2, 2014Assignee: International Business Machines CorporationInventors: Michael James Beckerle, Michael John Carney

Patent number: 7085246Abstract: An apparatus for acquiring a pseudo-random (PN) sequence timing for a code division multiple access (CDMA) radiotelephone. A buffer stores samples of representations of at least one pilot signal. A correlator coupled to the buffer is operable to correlate at least a portion of the samples with a PN sequence at each of a plurality of different PN offsets to produce corresponding correlation energies. A controller coupled to the correlator interrupts the correlator as soon as the PN sequence at a particular PN offset produces a correlation energy at least equal to an energy threshold.Type: GrantFiled: April 25, 2000Date of Patent: August 1, 2006Assignee: Motorola, Inc.Inventors: Christopher Peter LaRosa, Brian David Storm, Michael John Carney, Christopher Becker, Tracie Ann Schirtzinger, Dave Steckl

Patent number: 6243410Abstract: By time-sharing demodulator hardware between a primary data path (165), a power control data path (161), and a received signal strength indicator (RSSI) path (163), an entire power control data path (161) can be implemented in a demodulator (140) of a spread spectrum subscriber unit receiver with a low increase in gate count. The primary data path (165) and the power control data path (161) time-share a complex conjugate generator (270), a complex multiplier (280), and a real component extractor (290). Due to timing requirements, though, the channel estimation filter (240) of the primary data path cannot be time-shared with the power control data path. Instead, dynamic coefficient scaling is added to an infinite-duration impulse response (IIR) filter in the RSSI path (163) so that the IIR filter (250) with dynamic coefficient scaling can be time-shared between the RSSI path (163) and the power control data path (161).Type: GrantFiled: June 3, 1998Date of Patent: June 5, 2001Assignee: Motorola, Inc.Inventors: Christopher Peter LaRosa, Michael John Carney, Christopher John Becker

Patent number: 6228792Abstract: Supported Ziegler-Natta catalyst component adapted for the polymerization of ethylene is provided. More specifically, certain organomagnesium compounds (e.g., dibutylmagnesium) which do not contain an oxygen linkage between the organo moiety and the magnesium are impregnated into a porous inorganic oxide support (e.g., agglomerated silica particles) to form a first reaction product. The first reaction product is halogenated, e.g., with HCl, to convert the organomagnesium derived component to MgCl2 thereby forming a second reaction product. The second reaction product is then treated with a transition metal compound (e.g., TiCl4), a particular type of electron donor (e.g., 2,6-dimethyl pyridine) and optionally at least one Group 2 or 13 organo metal compound (e.g., diethylaluminum chloride). The combination of the particular organomagnesium compounds and electron donor impart a low melt flow ratio and enhanced activity to resulting catalyst component.Type: GrantFiled: February 27, 1998Date of Patent: May 8, 2001Assignee: W.

Patent number: 5903825Abstract: The digital FM receiver back end receives an analog intermediate frequency signal from a radio frequency front end (310) having a heterodyne circuit (312) and an intermediate frequency filter (314). In the receiver back end (307), a digital demodulator (330) having a hard limiter (333), a direct phase digitizer (336), and a phase differential circuit (339) produces a digital phase differential signal from the analog intermediate frequency signal. Next, a digital processor (360) filters and reduces noise in the digital phase differential signal using a bandpass filter (362), a de-emphasis filter (364), and an expandor (366). Finally, a pulse-width-modulation audio amplifier (380) prepares the signal for reproduction on an audio speaker (390). The digital FM receiver back end avoids inherent DC offset problems common to analog FM receivers, and it also offers a reduced complexity, size, and power consumption alternative to conventional digital FM receivers.Type: GrantFiled: June 27, 1996Date of Patent: May 11, 1999Assignee: Motorola, Inc.Inventors: Steven Howard Goode, James Clark Baker, Michael John Carney

Patent number: 5661433Abstract: In the digital FM demodulator (330), a hard limiter (333) receives a modulated analog IF signal and limits the voltage of the IF signal to two levels. Next, a direct phase digitizer (336) uses zero-crossings of the limited IF signal to generate N-bit digital words. A phase differential circuit (340) computes the phase shift of the signal from the direct phase digitizer over a predetermined time interval. The dynamic range of the phase differential signal can be increased by replacing the phase differential circuit (340) with a high-resolution phase differential circuit (700). After digital demodulation and filtering and gain control by audio processor (360), the recovered signal is forwarded to a speaker (390) to produce an audio output. Thus, the digital FM demodulator both avoids problems common to analog discriminator circuitry and offers a reduced complexity, size, and power consumption alternative to conventional digital FM demodulators.Type: GrantFiled: June 27, 1996Date of Patent: August 26, 1997Assignee: Motorola, Inc.Inventors: Christopher Peter LaRosa, Michael John Carney
