Techniques for generating multiple auditory scenes via highly directional loudspeakers
In one embodiment of the present invention, a central communications controller creates customized hearing experiences without unnecessarily encumbering listeners. In operation, for each listener, the central communications controller selects distracting and/or confidential sounds and generates a cancellation signal that substantially attenuates (i.e., “cancels out”) the selected sounds without corrupting remaining sounds. To selectively filter the sounds for a listener, the central communications controller leverages one or more highly directional loudspeakers to deliver the cancellation signal directly to the ears corresponding to the listener. More specifically, for a given ear, the central communications controller transmits the cancellation signal to a highly direction loudspeaker that targets the location of the ear. In this fashion, the central communications controller provides a listener-customized listening experience—selectively cancelling sounds at Identify sounds to be suppressed and generate ears—without relying on constraining sound delivery systems such as headphones, in-ear auditory devices, and the like. |

System providing faster and more efficient data communication
A system designed for increasing network communication speed for users, while lowering network congestion for content owners and ISPs. The system employs network elements including an acceleration server, clients, agents, and peers, where communication requests generated by applications are intercepted by the client on the same machine.

Current mode analog to digital converter with enhanced accuracy
A family of current mode analog to digital converters, or TiADC, utilizing methods, circuits, and apparatuses, are disclosed with the following benefits: (1) There are normal and random non-systematic mismatch between devices in silicon manufacturing, that introduce non-linearity in current mode analog to digital converter's, or iADC, reference network. The iADC's linearity is improved by utilizing a thermometer current mode signal conditioning method, SCM. Successive applications of the SCM effectuates a segmented current reference network to function like a thermometer network, which operates based on the function of summation. Having a TiADC with a thermometer reference network, where current segments are summed or accumulated incrementally, would inherently reduce the impact of statistical distribution of component's random mismatch on the iADC's non-linearity. Accordingly, linearity of TiADC can be improved by the square root of the sum of the square of mismatch errors of the number of segmented current references in the thermometer network. (2) speed is improved by operating the TiADC in current mode, which is inherently faster. (3) voltage swings in current mode are small, which enables he iADC to operate at lower power supply voltages. (4) The TiADC can operate in subthreshold and at very low currents, which lower powers consumption. (5) the TiADC is asynchronous. Being clock free, TiADC has lower dynamic power consumption with reduces digital system noise. (6) the signal conditioning method or SCM utilized in TiADC provides concurrent functions of analog differencing and digital comparison. This trait enhances the dynamic response of iADC, wherein the digital output throughput accuracy degrades gradually and not abruptly as a function of increasing frequency of iADC's input signal. (7) No passive devices, such as capacitors or resistors, are required for the TiADC. (8) TiADC can be fabricated on low cost mainstream standard digital CMOS processes. |

Dynamic sequential approximation register (SAR) analog-to-digital converter (ADC) (SAR-ADC) clock delay calibration systems and methods
A time-interleaved SAR-ADC employs calibrated SAR-ADC circuits to convert sampled voltage levels into serial digital data. Variable delay clock circuits synchronize clock signals received at the respective SAR-ADCs to sampling points of analog serial data. IC and environmental fluctuations cause delay in the variable delay clock circuits to skew the clock signals. A calibrated SAR-ADC detects changes to the delays in the variable delay clock circuits. By delaying a first clock signal in the variable delay clock circuit, and comparing a phase of the delayed clock signal to a phase-shifted clock signal having a known phase shift relative to the first clock signal, a change in the delay of the variable delay clock circuit can be detected as a phase difference. Based on an indication of a phase difference, a delay control signal is generated to control the delay in the variable delay clock. |
