Abstract: Methods, systems, and apparatuses for circuit boards are provided herein. An electrically insulating material is formed over one or more traces on a circuit board. One or more further electrically conductive features are present on the circuit board. A layer of an electrically conductive material is formed over the one or more traces that is electrically isolated from the one or more traces by the electrically insulating material, and is in electrical contact with the one or more further electrically conductive features. The electrically conductive material confines magnetic and electric fields produced when the one or more traces conduct an alternating current. By confining the magnetic and electric field distributions in this manner, problems of interference and/or crosstalk with adjacent signal traces are reduced or eliminated.

Abstract: A packet loss concealment method and system is described that attempts to reduce or eliminate destructive interference that can occur when an extrapolated waveform representing a lost segment of a speech or audio signal is merged with a good segment after a packet loss. This is achieved by guiding a waveform extrapolation that is performed to replace the bad segment using a waveform available in the first good segment or segments after the packet loss. In another aspect of the invention, a selection is made between a packet loss concealment method that performs the aforementioned guided waveform extrapolation and one that does not. The selection may be made responsive to determining whether the first good segment or segments after the packet loss are available and also to whether a segment preceding the lost segment and the first good segment following the lost segment are deemed voiced.

Abstract: A system and method is described for compensating for the effects of a corrupted Continuously Variable Delta Slope Modulation (CVSD) decoder memory state on a decoded audio signal. In accordance with the system and method, a first estimated step size associated with a first frame of the decoded audio signal is calculated and a second estimated step size associated with a replacement frame generated to conceal bit errors in the first frame of the decoded audio signal is calculated. At least a second frame of the decoded audio signal is then modified based on the first estimated step size and the second estimated step size.

Abstract: A system and method for encoding and decoding speech signals that includes a specially-designed Code Excited Linear Prediction (CELP) encoder and a vector quantization (VQ) based Noise Feedback Coding (NFC) decoder or that includes a specially-designed VQ-based NFC encoder and a CELP decoder. The VQ based NFC decoder may be a VQ based two-stage NFC (TSNFC) decoder. The specially-designed VQ-based NFC encoder may be a specially-designed VQ based TSNFC encoder. In each system, the encoder receives an input speech signal and encodes it to generate an encoded bit stream. The decoder receives the encoded bit stream and decodes it to generate an output speech signal. A system and method is also described in which a single decoder receives and decodes both CELP-encoded audio signals as well as VQ-based NFC-encoded audio signals.

Abstract: A voice activity detection (VAD) dependent retransmission scheme is described that mitigates the effect of packet loss on an audio signal transmitted between terminals in a wireless communication system in a manner that is generally more robust than conventional state-of-the art packet loss concealment algorithms but that consumes less terminal power as compared to conventional retransmission schemes. In one implementation, this is achieved by allowing retransmissions to be requested by a terminal only when a packet received by the terminal is deemed bad and when a portion of an audio signal currently being received by the terminal is deemed to comprise active speech. In other implementations, the processing of retransmission requests received by a terminal is inhibited or turned off entirely during periods when a portion of an audio signal currently being transmitted by the terminal is deemed not to comprise active speech.

Abstract: Packet loss concealment (PLC) systems and methods are described that use time-warping to merge a concealment signal generated to replace one or more bad frames of an audio signal with a received signal representing one or more subsequent good frames of the audio signal in a manner that avoids signal discontinuity and audible artifacts resulting therefrom. Prediction-based PLC systems and methods are also described that use time-warping to conceal the loss of one or more frames containing a transition region in a manner that will not result in an audible artifact.

Abstract: A bit error concealment (BEC) system and method is described herein that detects and conceals the presence of click-like artifacts in an audio signal caused by bit errors introduced during transmission of the audio signal within an audio communications system.

Abstract: A tokenization platform and method is described for accurately tokenizing character strings, including but not limited to non-delimited character strings of the type commonly used in Internet domain names and computer filenames, to accurately identify words and phrases occurring therein. In one embodiment, a phased tokenization approach is used in which the final phase is a lexical analysis-based tokenization using a dictionary. The dictionary may be advantageously created and updated based upon one or more query logs associated with respective information retrieval systems, thereby ensuring that the dictionary accurately reflects currently-used terminology and captures alternative spellings and presentations of words and phrases submitted by users.

Abstract: A method of generating an aggregated forecasting landscape for a particular advertiser's bidded term constructs standardized forecasting landscapes for each marketplace, rescales, by the advertiser's clickability in the respective marketplace, each of the standardized landscapes corresponding to the previous appearance of the advertiser's ad in that marketplace and whose appearance was attributed to the bidded term, and adds together the rescaled landscapes, thereby giving the advertiser a more accurate representation of how many total clicks he can expect for his advertisement as a function of how much he is willing/able to pay. In particular, estimation variance is reduced by introducing rank into the construction of the standardized landscapes, which increases the accuracy of the calculations.

Abstract: Methods, systems, and apparatuses for performing rate control for encoding of video frames are provided. A first timestamp is received that indicates a capture time for a prior video frame. A second timestamp is received that indicates a capture time for a current video frame. A time difference between the second timestamp and the first timestamp is determined. An average video data bit encoding rate is multiplied by the determined time difference to calculate a bit budget. An indication of a number of video data bits that have been encoded is received. The number includes a number of encoded video data bits of the prior video frame and of any further video frames encoded subsequent to the prior video frame and prior to the current video frame. A virtual buffer fill level is adjusted based on a difference between the indicated number of video bits that have been encoded and the calculated bit budget. A quantizer parameter is adjusted based on the adjusted virtual buffer fill level.

Abstract: Methods, systems, and apparatuses for determining battery state of health are provided. A battery that is substantially uncharged is charged with a substantially constant charge current. A time duration of the charging of the battery with the substantially constant charge current is determined. A state of health of the battery is estimated based upon the determined time duration and the constant charge current. The state of health of the battery may be calculated by multiplying the determined time duration with a value of the constant charge current to determine a total accumulated charge, and applying a predetermined factor to the accumulated charge to determine the state of health. The predetermined factor is a fixed percentage of the total charge capacity of the battery that corresponds to the battery type.
