Abstract: Embodiments disclosed herein improve digital stethoscopes and their application and operation. A first method detects of a respiratory abnormality using a convolution. A second method counts coughs for a patient. A third method predicts a respiratory event based on a detected trend. A fourth method forecasts characteristics of a future respiratory event. In a fifth embodiment, a base station is provided for a digital stethoscope.

Abstract: Systems and devices for, and methods of, interactive event casting, by: (a) scheduling a plurality of transactions, where the scheduling may be based on passing a system time and a channel usage schedule; (b) aggregating the plurality of transactions, where the aggregating results in minimizing data transfer traffic; (c) executing a data compression and error correction scheme, where the data compression scheme may be based on dynamically changing bitrate of a video data stream according to local access point data traffic; and (d) communicating between network devices using multi-cast for compressed video streams with error-correction code and (e) initiating an application, where the initiated application performs error correction, decompresses the received video data stream, and where the decompressed video data stream may be spooled.

Abstract: Systems, devices, and methods for encoding a plurality of images by an encoder where the encoder determines a set of subbands associated with an input image, determines a set of wavelet coefficients associated with each subband, generates a wavelet tree comprising a set of nodes and a maximum quantization level for a set of descendants of the set of nodes of the wavelet tree. Then, determines if the maximum quantization level is less than a threshold and sets the wavelet coefficient to zero if it is not, otherwise encodes the maximum quantization level, and encodes the set of wavelet coefficients for transmission in a bit stream comprising the encoded maximum quantization level and the encoded set of wavelet coefficients.

Abstract: Devices, methods, and systems for an orthogonal frequency division multiplexing (OFDM) receiver comprising a processor configured to execute a maximum likelihood timing estimator for OFDM symbol timing, a resampling filter for sampling clock frequency offset correcting via a loop filter, where the loop filter may be configured to receive a symbol timing loop error and provide, via a delay accumulator input signals to the resampling filter, and where the resampling filter may be configured to output a resampled signal for demodulating.
