Method and system to fully-automatically measure the ST-segment level of electrocardiograms in real-time ECG monitoring
A system for determining the Q and J points of an electrocardiogram (ECG) combines a WLT-based Q, J detection algorithm with signal quality assessment for lead selection. A Q, J detector (24) receives a beat-cycle waveform for the beat under consideration from each of a plurality (N) of ECG leads, and assesses signal quality for each lead using signal quality assessor (SQA) components 261, 262 . . . 26N. The leads with “good” signal qualities are employed for a multichannel waveform length transform (WLT), which yields a combined waveform length signal (CWLS). The Q and J points are then determined from the CWLS. |

Real-time biometric detection of oscillatory phenomena and voltage events
A system and method for identifying changes in a state or activity is described. A real-time event monitoring application, implemented in a hardware processor, computes features over varying sampling periods, which are stored in cascading buffers. The various sampling periods enable determination of trends of a computed feature, comparison of the trends of the computed feature with trends of other features, normalization of the computed feature based on the same or different features at the same or different time scales, scaling of the normalized computed feature relative to other features at the same or different time scale, and identification of a change in state or activity based on a scaled normalized computed feature. |

Measurement configuration and reporting with diverse traffic
A network node receiving a preference for a power optimized configuration for a user equipment (UE) can in response change the UE's minimization of drive test (MDT) configuration to conserve UE power. For example, this change can be from immediate reporting of MDT measurements to connected mode logging MDT measurements or no reporting of MDT measurements; or to a longer interval for reporting them, or to drop the reporting of available location information with MDT measurements. Other teachings have actions by the UE, autonomous of the network, to conserve power. A UE receiving a MDT configuration having an MDT measurement reporting or logging interval, and also one or both of a discontinuous reception or paging configuration having a DRX/paging interval can adapt the MDT configuration autonomously of the network to conserve its battery power. For example, the UE can change the MDT measurement reporting/logging interval to be equal to or shorter than the DRX/paging interval, or it can ignore or reject the MDT configuration. |

Special case handling for merged chroma blocks in intra block copy prediction mode
Innovations in intra block copy (“BC”) prediction facilitate handling of special cases when chroma blocks are merged for purposes of the intra BC prediction. For example, encoding includes intra BC prediction for a set of adjacent units (e.g., prediction units of a coding unit). An encoder derives a block vector (“BV”) value for secondary component blocks (e.g., chroma blocks) of the set of adjacent units using one or more of the BV values associated with the adjacent units. The encoding includes special case handling for any derived BV value referencing sample values outside a boundary (e.g., picture boundary, slice boundary, tile boundary). The special case handling can use constraints on values of the BVs, clipping of the derived BV value, or padding of sample values at the boundary. In some implementations, corresponding decoding includes special case handling. |
| US09591322B2 |
Coding using a redundant dictionary, such as video coding using a self-adaptive redundant dictionary including spatial and/or temporal prediction candidate atoms
An example video encoder uses a self-adaptive dictionary that only depends on the block location, without requiring real time design/redesign of the dictionary. A mean-removed block may be directly represented using a redundant dictionary including all possible inter-prediction candidates with integer motion vectors (mean-removed). In general the dictionary may also contain some intra-prediction candidates and some pre-designed fixed dictionary atoms. The coefficients may be determined by minimizing the L0 norm of the coefficients subject to a constraint on the sparse approximation error. Using such a self-adaptive dictionary can lead to a very sparse representation, with significantly fewer non-zero coefficients than using the DCT transform on the prediction error. Some example embodiments consistent with the present invention use a modified orthogonal matching pursuit (“OMP”) algorithm to orthonormalize each new chosen atom with respect to all previously chosen and orthonormalized atoms. Each image block is represented by the quantized coefficients corresponding to the orthonormalized atoms. |

More specifically, PUs of specified restricted sizes in bi-predicted slices (B slices) are forced to be uni-predicted. |

Dynamic request rerouting
A point of presence includes edge servers having IP addresses and storing content, a switch/router that receives and forwards requests for content to the edge servers, a health monitoring server that gathers health information from the edge servers, and a dynamic request rerouting (DRR) server. The DRR server is connected with each of the edge servers.
