Abstract: A heart monitoring system includes at least two sensors embedded in a seat, such as a driver's seat in a vehicle. One of the sensors obtains a phonocardiogram (PCG) of the driver's heart in addition to noise. Another sensor is a reference sensor that obtains a noise signal, but does not include the PCG signal. Processing circuitry receives the heart signal with the noise and the reference noise signal, and performs adaptive filtering to remove the noise from the heart signal. Further analysis detects a heart rate or other heart measurements in the heart signal, and may output an alert if a heart condition is detected.

Abstract: Reading, by a controller of the network, a first PLCA ID of each of N follower nodes of the network. First remapping, by the controller, each read first PLCA ID to one of N+1 unique remapped PLCA IDs. One PLCA ID of the N+1 unique remapped PLCA IDs is reserved for one of the follower nodes requesting a subsequent re-mapping of PLCA IDs. The N+1 unique remapped PLCA IDs start at a lowest PLCA ID and proceed through consecutive PLCA IDs.

Abstract: System and apparatus for real time electrocardiogram signal quality estimation. Systems and methods are disclosed for real time detection of corrupted segments of an electrocardiogram input signal and real time generation of an electrocardiogram based on an uncorrupted input signal. Systems and methods are provided for receiving a signal from an electrode, detecting corruption in a portion of the signal, and discarding the portion of the signal including the corruption.

Abstract: Disclosed herein are systems and techniques for content protection over synchronous data networks. For example, a method of communicating content protected data may include providing link synchronization information over a link of a synchronous bus, and providing content protected data over the link of the synchronous bus. The content protected data may be protected in accordance with the High-Bandwidth Digital Content Protection (HDCP) specification or the Digital Transmission Content Protection (DTCP) specification, for example.
