Abstract: A microelectronic device that in operation generates or includes component(s) that generate heat, in which the device comprises a heat conversion medium that converts such heat into a light emission having a shorter wavelength than such heat, to thereby cool the device and dissipate the unwanted heat by such light output. The heat conversion medium can include an upconverting luminophoric material, e.g., an anti-Stokes phosphor or phosphor composition. The provision of such heat conversion medium enables thermal management of microelectronic devices, e.g., optoelectronic devices, to be achieved in an efficient manner, to prolong the operational service life of devices such as LEDs, laser diodes, etc. that are degraded in performance by excessive heat generation in their operation.

Abstract: The present invention relates to apparatus for the storing and dispensing of products. A cartridge includes at least one sealing element adapted to engage an outer surface of an end of the cartridge to close the end of the cartridge and thereby contain dispensable contents of the cartridge. A substantially rigid outer casing is adapted to receive the cartridge. A removable member is configured to engage the at least one sealing element. The at least one sealing element is adapted such that the at least one sealing element is removed for removal from the cartridge upon removal of the removable member in a single step to enable the contents of the cartridge to be dispensed from the end of the cartridge.

Abstract: The present invention relates to a fabric sail (1) which maintains a minimal surface. An elastic boundary is attached to the edges of an elastic membrane, and the edges (4) are shaped so that the membrane of the sail maintains a minimal surface configuration despite being deformed by the boundary. The sail therefore distributes strain across the sail surface and is thus free of wrinkles and creases. Points on the elastic membrane itself can be displaced but still form a minimal surface as defined by the boundary and the displaced surface connection points. In addition, strain matching allows the boundary and the elastic membrane to optimally share the strain caused by any deformation.
