Abstract: An analog frontend (AFE) interface is dynamically programmable. A single AFE circuit can interface with multiple different analog devices, and dynamically configure its input for efficient interfacing with each different analog device. The AFE receives multiple unprocessed analog input signals and samples the analog input signals. A preprocessor element in the AFE analyzes the input signals and generates control signals based on the analyzing. The control signals dynamically adjust how the AFE samples the analog input signals, and can improve the efficiency of the operation the AFE.

Abstract: A wearable device (“WD”) stores a token after its wearer completes a successful strong authentication on a primary protected device (“primary PD”). Other protected devices (“secondary PDs”) recognize the stored token as representing a strong authentication and grant the user access while the user continues to wear the WD within a “digital leash-length” proximity. The WD constantly monitors whether the user continues to wear the device. Upon sensing that the user has removed the WD, the WD deletes, disables, or invalidates the token, The user must then repeat the strong authentication to gain further access to the protected devices.
