Abstract: A scheme is provided for dynamically adjusting an amount of power drawn from individual power sources to optimize the power usage without violating power limits. Coarse adjustment is provided through dynamic phase reallocation while a fine adjustment is provided through dynamic current steering. By adding a control loop around current steering techniques in digital voltage regulator controllers, power drawn from multiple input rails is balanced. The apparatus allows users to maximize the power delivered to discrete graphics cards without violating PCIe specifications. This allows maximum performance with minimal bill-of-material (BOM) cost.

Abstract: This application relates to a portable electronic device that includes an integrated pressure sensor. The portable electronic device includes a housing that defines a cavity with a number of components disposed therein. The cavity is sealed to form a volume of air within the cavity that is vented to the external environment through a barometric vent fluidly coupled to a first opening in the housing. A sensor measures a characteristic of a second volume of air within an isolated chamber that is vented to the external environment through a second opening in the housing. The second volume of air is isolated from the first volume of air within the housing of the portable electronic device. In some embodiments, the portable electronic device is a mobile phone and the sensor is a pressure transducer.

Abstract: A fluid channel formed with generally triangular-shaped performance enhancement features is disclosed. The fluid channels may be incorporated into heat exchanger or humidifier devices, the performance enhancement features generally having heat transfer and/or mass transfer performance enhancement applications. The heat transfer or mass transfer enhancement features are formed along the inner surfaces of the fluid flow passages of either the heat exchanger or humidifier plates and generally have sharp leading edges that create vortices in the fluid flowing through the passages. The heat or mass transfer enhancements protrude out of the inner surface of the fluid flow passages while leaving the outer surface of the fluid channel free of perforations. Alternatively, heat or mass transfer enhancements may be formed on separate inserts that are affixed to the inner surface of the fluid flow passages.

Abstract: A plate and fin type heat exchanger has a heat exchanger core made from a plurality of stacked, alternating first and second heat exchange plates of a generally inverted, U-shaped cross-section. Each plate has a top wall, closed peripheral sidewalls and open ends, and the open ends of the first plates are oriented at 90° to the open ends of the second plates. The sidewalls of the plates have end portions, which in adjacent plates, are aligned to form corners of the heat exchanger core. Opposed U-shaped manifold bodies are provided having open ends and lateral walls joined in a fluid tight manner to the aligned plate sidewall end portions. End plates close off the open ends of the U-shaped bodies to form manifolds. The corners formed by the aligned plate sidewall end portions allow for an improved connection between the heat exchanger core and the U-shaped manifold bodies.
