  • Patent number: 9413648
    Abstract: The embodiments described herein present methods and apparatuses for on-path CAC operations in a MPLS-VPN environment. In an example embodiment, an ingress PE device receives a quality of service (QoS) resource reservation request; constructs an outgoing message that includes information allowing an egress PE device to identify the virtual private network routing and forwarding table (VRF) associated with a resource reservation resulting from the QoS resource reservation request; and transmits the outgoing message to the egress PE device, where the information allowing VRF identification is echoed back by the egress PE device and used by the ingress PE device to identify the VRF associated with the resource reservation resulting from the QoS resource reservation request. Other embodiments are described.

  • Patent number: 9384726
    Abstract: A noise-cancelling system includes headset for generating a feedback signal for noise-cancellation in response to sound externally generated from the headset. The noise-cancellation feedback signal can also be described as a noise-cancellation “feed-forward” signal. An encoded microphone signal is generated in response to the first feedback signal. An audio generator can be used to generate a noise-cancellation signal in response to the encoded microphone signal and to generate an electronic audio signal in response to the encoded microphone signal and a first output audio signal. An audio connector is provided to couple the encoded microphone signal from the headset to the audio generator and to couple the first electronic audio signal to the headset.

  • Patent number: 9264217
    Abstract: In at least some embodiments, an electronic device includes a data sink and a buffer coupled to the data sink. The buffer is configured to receive streaming data in transit to the data sink. The electronic device also includes a clock drift compensation controller coupled to the buffer, wherein the clock drift compensation controller is configured to apply either of two predetermined clock drift compensation values to a clock rate for the buffer whenever a buffer fullness status value is offset from a predetermined threshold.

  • Patent number: 8385563
    Abstract: A system and method for controlling a sound level of a mobile audio device are disclosed herein. In accordance with at least some embodiments, a system includes a transducer, a phase estimator, and a sound level control. The transducer converts an electrical signal applied to the transducer into audible sound. The phase estimator estimates a phase difference between a voltage and a current of the electrical signal applied to the transducer. The sound level control controls the loudness of sound produced by the transducer based, at least in part on the estimated phase difference.

  • Patent number: 8190794
    Abstract: Instantiating a plurality of buffers in a random access memory by storing in the random access memory (RAM) a plurality of descriptors each containing a base address, at least one address pointer and a size to define a corresponding one of the plurality of buffers. Transferring data in any one of the plurality of buffers by using a control function within an accessing module to generate a buffer address by accessing and updating the address pointer in the corresponding descriptor. In a processor that accesses the circular buffers, the control function is one or more complex instructions tailored for computing read and write addresses to access the circular buffer using fields within the corresponding descriptor. In a DMA module that accesses the circular buffers, the control function is a hardware controller that computes read and write addresses using the fields within the corresponding descriptor to access the circular buffer.

  • Patent number: 8179235
    Abstract: A tactile input to a system having a speaker located in an enclosure with an audio port can be detected by generating a sound wave in response to a signal and sensing the phase relationship between the current phase and the voltage phase of the signal. While the audio port is open a baseline current and voltage phase difference is established. When the audio port is obstructed by a finger touch, the current and voltage phase difference is altered in response to the obstruction. While the altered phase difference is detected, a tactile event is indicated.

  • Patent number: 8064611
    Abstract: A system comprising audio logic adapted to convert captured sound into an audio signal. The system also comprises transmission logic which causes noise to be added to the audio signal. The system further comprises processing logic adapted to at least partially remove the noise from the audio signal by subtracting a noise waveform from the audio signal to produce a result signal. The processing logic generates the noise waveform using power level information associated with the transmission logic. The transmission logic transmits the result signal to another electronic device.

  • Patent number: 8050641
    Abstract: In at least some disclosed embodiments, a wireless electronic system includes a decoder module coupled to a processor. The decoder module is configured to send a signal to the processor based on a less than completely acquired burst of data. The less than completely acquired burst of data is part of a complete burst of data, and the complete burst of data is contiguous. The processor causes a reduction in power consumption of the wireless electronic system based on the signal.
