Abstract: Methods of fabricating tamper-respondent sensors with random three-dimensional security patterns are provided. The methods include establishing a security circuit pattern for a security circuit of a tamper-respondent sensor to enclose, at least in part, one or more components of a circuit board within a secure volume. The establishing includes determining in three-dimensions boundaries for the security circuit of the tamper-respondent sensor. The boundaries define a sensor volume which the security circuit is to fill in three dimensions. The establishing also includes generating at least one trace configuration for the security circuit pattern. The at least one trace configuration defines a random, three-dimensional security pattern to fill the sensor volume, and the at least one trace configuration establishes, at least in part, the security circuit pattern.

Abstract: Rechargeable battery monitoring and control is provided using a non-linear rate-of-change failure threshold. A non-linear rate-of-change failure threshold is obtained indicative of an operational state abnormality in a rechargeable battery cell, and during the operational state of the rechargeable battery cell, a control compares an actual voltage rate-of-change of the rechargeable battery cell to the non-linear rate-of-change failure threshold. Based on the actual voltage rate-of-change of the rechargeable battery cell exceeding the non-linear rate-of-change failure threshold, the control identifies the operational state abnormality in the rechargeable battery cell. Based on identifying the operational state abnormality in the rechargeable battery cell, the control discontinues the operational state of the rechargeable battery cell.
