Abstract: A cooling system for an electronics chassis includes a plurality of centrifugal blowers arranged to motivate cooling air through the electronics chassis. The centrifugal blowers are arranged in one or more sets, each having blowers oriented with respective inlets in mutual facing relationship. The orientation, positioning, and alignment of the centrifugal blowers facilitates a compact arrangement of the plurality of blowers that achieves increased aerodynamic efficiencies to reduce noise output and energy consumption.

Abstract: A cooling fan module for motivating air flow through an electronics chassis includes an enclosure having an air inlet through which cooling air flow is motivated by at least two centrifugal blowers disposed within the enclosure. The centrifugal blowers operate in parallel to motivate the cooling air flow along a first direction vector, while the respective axes of rotation of the centrifugal blower impellers are in substantial axial alignment with one another, and parallel to the first direction vector.

Abstract: A system for and method of rotating a transfer wheel providing heat and/or moisture exchange between two counter-flowing air streams. The system comprises: a frame; a transfer wheel including a transfer matrix mounted and rotationally secured relative to the frame so that the wheel can rotate through the two counter-flowing air streams and heat and/or moisture can be transferred between the two counter-flowing air streams; and a first plurality of motor components fixedly mounted relative to the wheel so that components of the first plurality function as a rotor of a motor, and a second plurality of motor components fixedly mounted relative to the frame so that components of the second plurality function as a stator of a motor; wherein power supplied to motor components of the second plurality causes the transfer wheel to rotate through the two counter-flowing air streams.

Abstract: An apparatus 10 provides an angled mirror 24 on a rear portion of the motor vehicle 12 that will be viewable in the side view mirror 12 to permit the driver 18 to see perpendicularly approaching traffic while backing out. The apparatus 10 is to be mounted on both sides of the vehicle 12 and may be manufactured in new vehicles or retrofit to existing ones. When manufactured in new vehicles 12, the apparatus 10 may be selectively adjusted by the driver using controls and technology similar to that currently in use for adjusting side view mirrors such as cables or RF signals. Furthermore, the mirror may be retractable to sit flush with the body of the vehicle 12 to maintain the aerodynamic properties thereof. Many other features may be integrated with the apparatus 10 such as a heating element for defrosting/defogging the mirror, a protective door that covers the mirror when in the retracted position and so forth.
