Patent number: 8988122Abstract: A terminal includes control logic to control a phase-locked loop to output a spread-spectrum clocking signal. The control logic controls the generation of the spread-spectrum clocking signal by adjusting at least one parameter of the phase-locked loop. The parameter may be a charge pump setting or a loop-filter capacitance of the phase-locked loop, or their digital equivalents. Adjustment of the parameter reduces a predetermined portion of a communications spectrum. The predetermined portion may be located within a range of frequencies allocated to a specific channel, and reduction of the spectrum in this range may serve to reduce noise associated with clocking harmonics.Type: GrantFiled: September 30, 2011Date of Patent: March 24, 2015Assignee: Intel CorporationInventors: Ewunnet Gebre-Selassie, Dawson W. Kesling, Steven J. Kirch, Rahul D. Limaye, Shah M. Musa, Fugao Wang

Publication number: 20100267013Abstract: The methods and apparatus disclosed herein concern nucleic acid sequencing by enhanced Raman spectroscopy. In certain embodiments of the invention, nucleotides are covalently attached to Raman labels before incorporation into a nucleic acid. In other embodiments, unlabeled nucleic acids are used. Exonuclease treatment of the nucleic acid results in the release of labeled or unlabeled nucleotides that are detected by Raman spectroscopy. In alternative embodiments of the invention, nucleotides released from a nucleic acid by exonuclease treatment are covalently cross-linked to nanoparticles and detected by surface enhanced Raman spectroscopy (SERS), surface enhanced resonance Raman spectroscopy (SERRS) and/or coherent anti-Stokes Raman spectroscopy (CARS). Other embodiments of the invention concern apparatus for nucleic acid sequencing.Type: ApplicationFiled: May 24, 2007Publication date: October 21, 2010Applicant: INTEL CORPORATIONInventors: Xing Su, Andrew Arthur Berlin, Selena Chan, Steven J.

Patent number: 7505193Abstract: A spatial light modulator may be adapted to receive bi-directional drive signals. The spatial light modulator may include a plurality of pixel elements having individual first electrodes and a common electrode providing a second electrode for each of the pixel elements. The pixel elements may be adapted to change between a first state and a second state in accordance with signals applied thereto, and the bi-directional drive signals may include at least a first drive signal and a second drive signal. Both drive signals are applied to change the pixel elements from the first state to the second state and from the second state to the first state.Type: GrantFiled: March 17, 2006Date of Patent: March 17, 2009Assignee: Intel CorporationInventors: Steven J.

Patent number: 7465578Abstract: The methods, compositions and apparatus disclosed herein are of use for nucleic acid sequence determination. The methods involve isolation of one or more nucleic acid template molecules and polymerization of a nascent complementary strand of nucleic acid, using a DNA or RNA polymerase or similar synthetic reagent. As the nascent strand is extended one nucleotide at a time, the disappearance of nucleotide precursors from solution is monitored by Raman spectroscopy or FRET. The nucleic acid sequence of the nascent strand, and the complementary sequence of the template strand, may be determined by tracking the order of incorporation of nucleotide precursors during the polymerization reaction. Certain embodiments concern apparatus comprising a reaction chamber and detection unit, of use in practicing the claimed methods. The methods, compositions and apparatus are of use in sequencing very long nucleic acid templates in a single sequencing reaction.Type: GrantFiled: July 7, 2004Date of Patent: December 16, 2008Assignee: Intel CorporationInventors: Andrew Berlin, Steven J.

Patent number: 7151521Abstract: A pixel is driven with pulse width modulation (PWM). A cycle for the PWM signal is divided into a plurality of super-intervals. Each of the super-intervals is divided into a plurality of intervals. An interval index is stored for the pixel. The timing at which the pixel is changed from one state to another is selected based on an enable signal and the stored interval index.Type: GrantFiled: March 31, 2003Date of Patent: December 19, 2006Assignee: Intel CorporationInventors: Thomas E.

Patent number: 5149974Abstract: An ion beam structure includes a gas container, such as a cylindrical can having first and second apertures through the center of the top and bottom walls respectively of the container such that a narrow ion beam is passed through the apertures and the center axis of the can and onto a target specimen such as a mask or chip or other article of manufacture disposed closely below the bottom of the can. The can may further include deflection means for applying voltages and/or magnetic fields to locations on the can (i.e., top, bottom, sides) to direct secondary charged particles such as electrons emitted from the specimen onto an electron detection means such that the structure functions as an imaging system. The electric and/or magnetic fields may be employed to increase the collection efficiency of the detector and thereby improve the quality of the image by increasing the signal to noise ratio.Type: GrantFiled: October 29, 1990Date of Patent: September 22, 1992Assignee: International Business Machines CorporationInventors: Steven J.

Patent number: 4923772Abstract: The present invention is a mask and methods for making masks for use with a laser projection etching system. The unique mask is able to withstand the fluences of the high energy and high power lasers used without degrading. Specifically, the new projection etching masks are fabricated of patterned multiple dielectric layers having alternating high and low indices of refraction on a UV grade synthetic fused silica substrate in order to achieve maximum reflectivity of the laser energy in the opague areas and maximum transmissivity of the laser energy in the transparent areas of the mask.Type: GrantFiled: April 17, 1989Date of Patent: May 8, 1990Inventors: Steven J.
