Abstract: There is disclosed a missile comprising an outer skin, an electronics unit, and a thermal link between the electronics unit and the outer skin. The thermal link comprises a jumping drop vapour chamber arranged such that, when the outer skin is at an elevated temperature relative to the electronics unit, the electronics unit is thermally insulated from the outer skin; and such that, when the outer skin is at a lower temperature relative to the electronics unit, the electronics unit is thermally linked to the outer skin.

Abstract: A system, method and apparatus that provides buying information and recommendations to help consumers purchase products from retail merchants when prices are at their lowest relative point rather than when the consumer runs out and needs to purchase at a higher price. The system provides electronic access to a plurality of product information from a plurality of retail merchants in a plurality of markets. For each regularly purchased product the system displays the lowest price available from a plurality of retail merchants. It also displays a price index that indicates how the current lowest price compares with the high and low price recorded for the product over a defined period of time, a re-order index that forecasts when the consumer is expected to run out of the product and a unit price index that indicates how the current unit price compares with the unit prices of a group of similar products.
