Abstract: In an example, a method comprises providing a layer of build material on a support, and applying energy to the layer of build material using an energy source. The method may further comprise reducing a spacing between the energy source and the support and following the reduction of the spacing, applying energy to the layer of build material using the energy source to cause fusion in at least part of the layer of build material.

Abstract: Example embodiments disclosed herein relate to a computing system including a controller hub to control system sleep states, and an embedded controller including an internal timer. The embedded controller is to remove power from the controller hub when the system enters a sleep state and to enable power to the controller hub prior to the system wake time. The internal timer is to determine when to enable power to the controller hub. Example methods and machine-readable storage media are also disclosed.

Abstract: A power supply system (10) and method (150) are disclosed. The system (10) includes a power converter (16) to provide an output voltage to a load (12) based on an input voltage that is generated from an AC supply voltage. The system (10) also includes a power monitor (16) to monitor the load (12). The system (10) further includes a filter stage (14) to dynamically filter high frequency currents generated by the power converter (16) from the AC supply voltage to substantially maximize a power factor associated with the power supply system (10).

Abstract: The specification may disclose a computer system and related method of checking for proper operation of a computer system, and taking corrective action if the computer system is not functioning properly. A monitoring device within the computer system may be programmed to actively monitor computer system operation, and take corrective action upon a failure of one or more computer system components.
