Abstract: A sensor module for a wearable vital sign monitoring device is disclosed. The sensor module includes a substrate having a first side and a second side opposite the first side. The sensor module also includes a sensor die mounted to the first side of the substrate. The sensor die is configured to monitor a vital sign of a user. The sensor module further includes a waterproof coating that conformally covers the sensor die, at least a portion of the first side of the substrate, and at least a portion of the second side of the substrate.

Abstract: Herein disclosed are approaches for protecting sensitive information within a fingerprint authentication system that can be snooped and utilized to access the device, secured information, or a secured application. The approaches can utilize encryption keys and hash functions that are unique to the device in which the fingerprint authentication is being performed to protect the sensitive information that can be snooped.

Abstract: There is disclosed herein examples of systems and methods for compressing a signal. Samples of the signal can be segmented and the samples within each of the segments can be averaged to produce a value that can represent the samples within the segment. The number of samples to average in each segment may be determined based on an error threshold, such that the number of samples being averaged can be maximized to produce less data to be transmitted while maintaining the representation of the samples within the error threshold. In some embodiments, a signal can be separated into a timing reference, a representative periodic function, and a highly compressible error signal. The error signal can be utilized for reproducing a representation of the signal.
