  • Publication number: 20240027290
    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.

  • Publication number: 20220206875
    Abstract: A processor is described. The processor includes model specific register space that is visible to software above a BIOS level. The model specific register space is to specify a granularity of a processing entity of a lock-step group. The processor also includes logic circuitry to support dynamic entry/exit of the lock-step group's processing entities to/from lock-step mode including: i) termination of lock-step execution by the processing entities before the program code to be executed in lock-step is fully executed; and, ii) as part of the exit from the lock-step mode, restoration of a state of a shadow processing entity of the processing entities as the state existed before the shadow processing entity entered the lock-step mode and began lock-step execution of the program code.

  • Publication number: 20220091652
    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).
