Abstract: Systems and methods for measuring web tension distribution in roll-to-roll processes, for example, such as R2R processes employed in the fabrication of printed devices. Such systems and methods entail a web that travels between first and second rollers in a longitudinal direction of the web, inducing tension in the web in the longitudinal direction thereof such that tension is present in a flexible substrate of the web between the first and second rollers, and operating the system to determine an average tension and linear variation of tension present in the flexible substrate resulting from the tension induced in the web inducing a nonuniform tension distribution in the flexible substrate between the first and second rollers. The systems and methods utilize one or more devices that induce deflection in the web between the first and second rollers.

Abstract: In one embodiment, an apparatus includes: first and second cores to execute instructions, and an interface circuit coupled to the first and second cores. In a lockstep mode in which the first and second cores are to execute redundantly, the interface circuit is to identify a miscompare between the first core and the second core that is due to a corrected error in one of the first core or the second core, and indicate the miscompare as a recoverable error. Other embodiments are described and claimed.

Abstract: Examples described herein relate to at least one multi-core processor and a circuitry can determine and output energy usage of a process regardless of a core of the at least one multi-core processor that executes the process. The circuitry can determine the energy usage of the process based on cache operations and processor microoperations associated with the process. The energy usage of the process can be based on dynamic capacitance (Cdyn) levels and one or more of: temperature of the at least one multi-core processor, input voltage temperature to the at least one multi-core processor, and/or frequency of the at least one multi-core processor.

Abstract: Described is a controller that provides in-situ state retention using a closed loop global retention clamp. The controller addresses di/dt and reliability constraints using an adaptive scheme where steps with smaller current are quickly changed whereas steps with larger current are changed slowly. The loop controller of a voltage regulator is modified for controlling not only retention Vmin during a low power state (e.g., C1LP), but also to control fast wake up the low power state (e.g., from C1LP and from C6).
