Abstract: Disclosed are various embodiments for controlling the switching frequency of a switching device of a power converter. Measured or computed parameters are obtained. One or more of the parameters are real-time measurements from one or more sensors. A controller selects one of the parameters as a target parameter. The target parameter is represented as an objective function that defines criteria for optimizing the objective function as minimizing, maximizing, or obtaining a particular value for the target parameter. The controller implements a machine learning algorithm to determine a selected switching frequency of the switching device that optimizes the objective function, and controls the switching device to operate at the selected switching frequency.

Abstract: Thermal interface system, and method thereof, are configured to constrain or limit an amount of compression applied to a thermal interface during insertion of an electronic device into a cage, rack, chassis, or other mounting assembly. The thermal interface system and method provide a thermal interface that is embedded within a pocket or cavity formed either on a surface of the device, a surface of the mounting assembly, or both. The thermal interface may be made of any suitable thermally conductive interface material that is resilient or has elastic properties. The pocket or cavity provides a seating for the thermal interface and operates to limit the compression or clamping force directed through the thermal interface. Such an arrangement helps prevent the full compression or clamping force used to secure the electronic device from being applied to the thermal interface.

Abstract: A drink container has a liquid-tight film pouch which is collapsible into a substantially flat condition. Drink ingredients in a solid or condensed liquid state can be stored in or added to the pouch through an opening in an upper portion of the pouch. A cover with a liquid tight seal closes the opening. A dispense opening with a straw may be provided, or the beverage can be dispensed through the fill opening. The openings, straws and cover are located and contoured to conform with the desired substantially flat storage condition.
