Abstract: A method and system to provide visualization of high resolution terrain for use in real-time simulation for digital image displays that is derived directly from source data including imagery, classification, elevation and vector data at run-time with little or no off-line manipulation of the source data. The fidelity of the visualization is scalable based on the graphic system's capability. Readily available worldwide data exists for imagery, classification, elevation, vector and airport runway data.

Abstract: An insect repellent composition that includes a blend of either all natural oils or synthetic ingredients, a sunscreen vitamin F, volatile silicones to extend the effective repellent life of the spray and a film forming polymer to resist water wash off. The natural oils and extracts can include citronella and orange and the synthetics can include D-limonene and phtalic acid.

Abstract: A method for increasing the firmness of a pillowtop or any other soft mattress. The method includes providing a rectangular sheet of cotton fabric material having hook fasteners on one end and loop fasteners on an opposite end to attach the sheet of material around the mattress. The firmness of the mattress is increased by tightly wrapping the sheet of material around the mattress using the fasteners. The sheet of material is sized appropriately to fit entirely around the mattress with overlap. Preferably, the sheet of material is sized and manufactured for wrapping longitudinally around the mattress.
