Abstract: An illustrative embodiment of a disclosed physical layer interface device includes: a first transmitter and a first receiver for a primary data path; a second transmitter and a second receiver for a secondary data path; a third transmitter and a third receiver for a non-redundant data path; and a multiplexer. The third receiver is coupled to provide a data stream received from the non-redundant data path concurrently to the first and second transmitters, and the multiplexer provides the third transmitter with a selected one of the data stream received via the primary data path and the data stream received via the secondary data path. Disclosed network switch embodiments employ the illustrative physical layer interface to provide internal or external data path redundancy for traffic handled by the network switch.

Abstract: A wearable device includes one or more sensors of information from a subject. The wearable device may have an electronic assembly supported by a base. The electronic assembly may include a sensor data collection system configured to control collection of sensor data related to one or more characteristics of a subject and one or more processors. the sensor data collection system may include a controller configured to control sequencing and scheduling of the sensor data collection, and a buffer configured to receive and buffer data corresponding to the sensor data collected from the one or more sensors in accordance with a signal provided by the controller. The one or more processors may be configured to receive the buffered data from the buffer in accordance with a wake signal; process the received data; and output the processed data.

Abstract: A biosensor screening system and method is disclosed that assesses functional integrity/capacity of biosensor samples and identifies the biosensor samples that may potentially cause failure such as shutdown of biosensor during normal use. Features of the disclosed biosensor screening system and method may include connecting to a biosensor to a biosensor screening test apparatus, conducting a biosensor screening test using the biosensor screening apparatus on the biosensor connected to the biosensor screening test apparatus, collecting data attributes from the biosensor after completing the biosensor test, scaling the collected data attributes, and obtaining a screening test score.
