Abstract: Techniques relating to information technology (IT) are disclosed. These techniques include identifying a token relating to embodied emissions for an IT hardware component. The techniques further include determining embodied emissions for the IT hardware component that have been offset, based on the token. The techniques further include recording the offset of the embodied emissions for the IT hardware component, including: modifying a sticky bit for the IT hardware component, wherein the sticky bit reflects the offset of the embodied emissions, wherein the modification of the sticky bit is irreversible, and wherein the sticky bit is integrated into the IT hardware component.

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.

Abstract: Disclosed embodiments provide methods, systems, and computer program products for implementing predictive three-phase power distribution unit (PDU) output load switching for input phase balancing. Disclosed embodiments measure PDU output port power values for powering a plurality of loads over time, perform pattern recognition on the PDU output port power values over time to produce recognized power patterns; and create switching rules based on the recognized power patterns to provide input phase load balancing, wherein the switching rules include at least one of (i) predicted output port power values for a periodic time interval, or (ii) predicted output port power values based on the measured PDU output port power values associated with the loads. Disclosed embodiments switch input phase connection to one or more PDU outputs based on the switching rules.

Abstract: Tamper-respondent sensors with random three-dimensional security patterns and methods of fabrication are provided. The method includes 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 obtaining in three-dimensions boundaries for the security circuit of the tamper-respondent sensor. The boundaries define a sensor volume within which the security circuit is to reside. 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 within the sensor volume, and the at least one trace configuration establishes, at least in part, the security circuit pattern. The process further includes fabricating the tamper-respondent sensor using, at least in part, the established security circuit pattern.
