摘要： Cardiac monitoring and/or stimulation methods and systems that provide one or more of monitoring, diagnosing, defibrillation, and pacing. Cardiac signal separation is employed to detect, monitor, track and/or trend a patient's posture using cardiac activation sequence information. Devices and methods in accordance with the present invention involve sensing a plurality of composite cardiac signals using a plurality of implantable electrodes. A source separation is performed using the composite cardiac signals, which produces one or more cardiac signal vectors associated with all or a portion of one or more cardiac activation sequences. A change in a patient's posture is detected using the cardiac signal vectors. Further embodiments involve sensing the plurality of composite cardiac signals during the patient's predominant cardiac rhythm before detecting the change in the patient's posture. Other embodiments involve discriminating between one of a postural related change and a cardiac rhythm related change using the cardiac signal vectors.

摘要： Cardiac monitoring and/or stimulation methods and systems provide monitoring, defibrillation and/or pacing therapies. A signal processor receives a plurality of composite signals associated with a plurality of sources, separates a signal using a source separation algorithm, and identifies a cardiac signal using a selected vector. The signal processor may iteratively separate signals from the plurality of composite signals until the cardiac signal is identified. The selected vector may be updated if desired or necessary. A method of signal separation involves detecting a plurality of composite signals at a plurality of locations, separating a signal using source separation, and selecting a vector that provides a cardiac signal. The separation may include a principal component analysis and/or an independent component analysis. Vectors may be selected and updated based on changes of position and/or orientation of implanted components and changes in patient parameters such as patient condition, cardiac signal-to-noise ratio, and disease progression.

摘要： A nondefibrillating and nonfibrillation-inducing energy is delivered at a first internal thoracic location. A first resulting electrical signal is detected at a second internal thoracic location in or near a target region of a heart. A first defibrillation threshold is estimated using the nondefibrillating and nonfibrillation-inducing energy, the first resulting electrical signal, and a target electric field strength. The defibrillation threshold represents an energy that when delivered at the first internal thoracic location creates an electric field strength in the target region of the heart that meets or exceeds the target electric field strength.

摘要： System and techniques for base station assisted Information Centric Network (ICN) are described herein. A mobile network base station receives an ICN packet from a user equipment (UE). The mobile network base station identifies an aggregate packet data unit (PDU) session with a user plane function (UPF) ICN gateway (ICN-GW) hosted in a mobile network core network (CN) for the ICN packet. Then, the mobile network base station transmits the ICN packet via the aggregate PDU session.

摘要： This disclosure describes systems, methods, and devices related to latency reduction. The device may set up a plurality of links between an access point (AP) multi-link device (MLD) and a non-AP MLD. The device may encode a frame for transmission on a first link of the plurality of links between a first AP of the AP MLD and a first STA of the non-AP MLD. The device may identify an indication received at a second STA of the non-AP MLD using an interference mitigation signal. The device may cause to stop the transmission of the frame on the first link based on the indication. The device may identify a second frame on the first link received from the first AP. The device may cause to resume the transmission of the first frame on the first link.

摘要： An antenna includes a metal tube, a coaxial cable disposed along a central axis of the metal tube, and a variable-impedance transmission wire structure. A dielectric body and a metal part are arranged along an axial direction of the cable. The antenna makes the resulting structure stable and reliable, achieves miniaturization of a multi-band antenna and provides a sufficiently wide bandwidth for each frequency band. The antenna also realizes easy control of the radiation pattern and is convenient for practical applications.

摘要： Systems and techniques for mission critical (MC) push notification mechanism in a high-reliability (HR) information centric network (ICN) are described herein. For example, a node may test network links to other nodes to classify the other nodes into proximate nodes and non-proximate nodes based on a reception metric. The node may then elect a set of leader nodes from the proximate nodes. Here, the set of leader nodes are selected based on link quality between respective leader nodes and non-proximate nodes. The node may detect an MC event and create an ICN data packet that contains data from the MC event. The node may then transmit the ICN data packet to the set of leader nodes that then relay the ICN data packet to the non-proximate nodes.

摘要： Disclosed is a dean production method for bamboo fibres, comprising the following steps: bamboo pieces are separated into filaments, and the filaments are twisted into ropes to obtain rope-shaped bamboo filaments; the rope-shaped bamboo filaments are refined by means of multiple alternating cold-hot treatments and rolling and rubbing to obtain coarse rope-shaped bamboo fibres (wherein same can be directly put into a drying device and then made into coarse bamboo fibres for a composite material); the coarse rope-shaped bamboo fibres are subjected to continuous biological degumming to obtain the rope-shaped bamboo fibres; the rope-shaped bamboo fibres are fed into a cleaning device for repeated cleaning, rolling and drying are performed, and then spraying-type oiling is performed to obtain thin rope-shaped bamboo fibres; finally, the thin rope-shaped bamboo fibres are subjected to opening and carding to make bamboo fibres for a textile material.
