| 20120091531 | Flexible Integration of Logic Blocks with Transistors of Different Threshold Voltages - An integrated circuit constructed according to an arrangement of logic blocks, with one or more logic blocks including transistors of a different threshold voltage than in other logic blocks. Spacing between neighboring active regions of different threshold voltages is minimized by constraining the angle of implant for the threshold adjust implant, and by constraining the thickness of the mask layer used with that implant. These constraints ensure adequate implant of dopant into the channel region while blocking the implant into channel regions not subject to the threshold adjust, while avoiding shadowing from the mask layer. Efficiency is attained by constraining the direction of implant to substantially perpendicular to the run of the gate electrodes in the implanted regions. | 04-19-2012 |

| 20110125423 | THERMAL INSPECTION SYSTEMS - A thermal inspection system includes a fluid source configured to supply a warm flow and a cool flow, indirectly or directly, to internal passage(s) of a component. The system includes an imager configured to capture a time series of images corresponding to a transient thermal response of the component to the warm and cool flows. The system further includes at least one flow meter configured to measure the warm and cool flows supplied to the component and a processor operably connected to the imager. The processor determines the transient thermal response of the component around a transition time. The flow supplied to the component switches from the warm flow to the cool flow at the transition time. The processor compares the transient thermal response around the transition time with one or more baseline values or with an acceptable range of values to determine if the component meets a desired specification. | 05-26-2011 |

| 20080229128 | System and Computer Program Product for Dynamically Managing Power in MicroProcessor Chips According to Present Processing Demands - A method, system, and computer program product are disclosed for dynamically managing power in a microprocessor chip that includes physical hardware elements within the microprocessor chip. A process is selected to be executed. Hardware elements that are necessary to execute the process are then identified. The power in the microprocessor chip is dynamically altered by altering a present power state of the hardware elements that were identified as being necessary. | 09-18-2008 |
| 20110271079 | MULTIPLE-CORE PROCESSOR SUPPORTING MULTIPLE INSTRUCTION SET ARCHITECTURES - A multiple-core processor supporting multiple instruction set architectures provides a power-efficient and flexible platform for virtual machine environments requiring multiple support for multiple instruction set architectures (ISAs). The processor includes multiple cores having disparate native ISAs and that may be selectively enabled for operation, so that power is conserved when support for a particular ISA is not required of the processor. The multiple cores may share a common first level cache and be mutually-exclusively selected for operation, or multiple level-one caches may be provided, one associated with each of the cores and the cores operated as needed, including simultaneous execution of disparate ISAs. A hypervisor controls operation of the cores and locates a core and enables it if necessary when a request to instantiate a virtual machine having a specified ISA is received. | 11-03-2011 |

| 20100215193 | Speaker Distortion Deduction System and Method - Many speakers, especially small speakers are susceptible to distortion if too much power is applied in certain vulnerable frequency bands. The distortion can be prevented by applying equalization to the audio signal driving the speaker. An equalizer can be configured to suppress the audio signal in the vulnerable frequency bands. The equalizer monitors the power in the vulnerable frequency bands and suppresses those vulnerable frequency bands only when they have sufficient power to distort. In this fashion, undesired audio effects due to the equalization can be avoided. | 08-26-2010 |
| 20110002471 | SYSTEMS AND METHODS FOR TRANSDUCER CALIBRATION AND TUNING - Audio transducers (headphones, speakers, microphones) inherently do not accurately reproduce the signal presented to them at the input. This can be compensated for by taking into account the transducer characteristics and transforming the input signal using a digital signal processor (DSP) to counteract the inaccuracies. However, for the compensation to take place, the DSP needs to know the characteristics of the transducer. For systems with built-in transducers (like laptops with internal speakers) the characteristics of the internal speakers can be stored on the hard-drive of the laptop and the DSP can read this data and make the appropriate compensations. Because a transducer (headphone, speaker, microphone) has its own characteristics that need to be compensated for separately, a profile is supplied to the DSP either by a database lookup based on an identification made by the user or transducer itself or by profile information stored on the transducer. Once the characteristics of a transducer are known, many additional DSP algorithms can be applied in order to improve the audio performance and even safety of the system. | 01-06-2011 |
| 20120002819 | AUDIO DRIVER SYSTEM AND METHOD - A grounding switch is described which operates properly even in the presence of negative voltages on a signal line. The grounding switch uses isolated field effect transistors that have their substrates tied to different voltages. The isolated field effect transistor has gate voltage and substrate voltage which can be pulled down to negative voltage when the signal line has a negative voltage allowing the switch to remain open even with a negative voltage. | 01-05-2012 |
