A method and apparatus for adding inductance is disclosed. Inductance may be added to a transmission line coupled to a printed circuit board to increase the inductance associated with a transmission line by utilizing ferromagnetic materials.

Method and apparatus for adding inductance to printed circuits

A fluid moving system is disclosed wherein a plurality of stacked blowers may provide for the redundant supply of cooling fluid such as air. This system may be advantageously utilized to cool electronic equipment or other uses. One or more of the blowers may utilize an impellor design that allows for the axial flow of fluid through the blower in addition to a transverse fluid outlet. In addition, the blowers may incorporate a flow gate operative to reduce back flow should a particular blower have a reduced fluid flow.

Stacked redundant blowers

Embodiments of the present invention may provide for high-density and high speed interconnections while maintaining reduced signal interference. In some embodiments, differential signals are organized in connectors such that differential signal pairs are orthogonal to each other. In other embodiments, differential signal tri-conductor sets may be oriented such that they are generally orthogonal to each other. The orthogonal contact organization may provide for reduced coupling between differential signals.

Low cost high speed connector

A chassis with an adaptive fan control is provided for electronic equipment. The adaptive fan control is responsive to at least one condition within one or more airflow sections within the chassis and may increase or decrease airflow in response to the condition.
