Publication number: 20120219068Abstract: Techniques are disclosed for employing a set of stream processors to greatly accelerate common video encoding and transcoding tasks, with the goal of making these tasks run at a reasonable rate on off-the-shelf hardware. Stream processors are most commonly found in the graphics processing unit (GPU), a commodity piece of computer hardware used to generate images for display. Embodiments of the invention are particularly advantageous to accelerate video encoding and transcoding tasks in which the blocks being processed have dependencies on their neighboring blocks.Type: ApplicationFiled: May 3, 2012Publication date: August 30, 2012Applicant: Elemental Technologies, Inc.Inventors: Jesse J.

Publication number: 20120175616Abstract: A thin film field effect transistor is disclosed which provides improved time-based channel stability. The field effect transistor includes first and second disordered semiconductor layers separated by an insulator. In an embodiment a carrier injection terminal is provided in a thin semiconductor layer closest to the gate terminal. An electric field is established in the thin semiconductor layer. At sufficient field strength, the electric field extends into the second semiconductor layer, which is in contact with the source and drain terminals. At sufficient field strength a channel is established in the second semiconductor layer, permitting current to flow between source and drain terminals. Above a certain gate voltage, there is sufficient free charge is induced in the first semiconductor layer so that the field does not extend into the second semiconductor, effectively shutting off current between source and drain. Single-device transition detection (as well as other applications) may be obtained.Type: ApplicationFiled: March 21, 2012Publication date: July 12, 2012Applicant: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Sanjiv Sambandan, Ana Claudia Arias, Gregory Lewis Whiting

Publication number: 20120148122Abstract: An apparatus for reducing noise in fingerprint sensing circuits is disclosed in one embodiment of the invention as including a fingerprint sensing area onto which a user can apply a fingerprint. An analog front end is coupled to the fingerprint sensing area and is configured to generate an analog response signal. An analog-to-digital converter (ADC) samples the analog response signal and converts the sample to a digital value, which may be received by a digital device such as a processor or CPU. To reduce the amount of the noise that is present in the analog response signal and therefore reflected in the digital value, the digital device may be shut down while the ADC is sampling the analog response signal.Type: ApplicationFiled: February 13, 2012Publication date: June 14, 2012Inventors: Gregory Lewis Dean, Richard Alexander Erhart, Jaswinder Jandu, Erik Jonathan Thompson
