Abstract: The vented heat shield is a device with a plurality of shapes, materials or colors which prevents sunlight from heating the roof or exposed surface of a vehicle by blocking the sunlight from the roof or exposed surface of the vehicle and creating an air gap allowing the movement of air in the gap to dissipate heat from both the protected surface and the heat shield. The action of blocking the heat from the sun reduces the rate of heat build up inside the vehicle and the air gap provides a means for ambient air flow to dissipating the heat from the protected surfaces of the vehicle and the heat shield. The shield can be permanent or removable. It is intended that the device be functional whether the vehicle is moving or stationary.

Abstract: Method and apparatus for providing data recovery in a one or multiple disk loss situation in a RAID5 like system. A data storage apparatus has a plurality of n disks storing data comprising a plurality of n data groupings stored across the plurality of n disks. Each one of the n data groupings comprises a data portion and a redundancy portion. The size of the data portion relative to the redundancy portion is as H to Q, where H/Q<(n?m)/m, where m is the maximum number of disks that may be lost at any given time. Advantageously, the n data portions are recoverable from any and all combinations of n-m data grouping(s) on n?m disk(s) when the other m data grouping(s) are unavailable, where 1?m<n.
