  • Patent number: 7025466
    Abstract: A rugged portable projector unit is suitable for transport and easy set-up. A projector is mounted to a rigid subframe by a mounting platform. A shock absorbing element is provided between the subframe and the mounting platform. The subframe is mounted within a hardened carrying case. Shock absorbing elements are provided between the subframe and the carrying case. The top of the carrying case is removable. A mirror is hingedly attached to the top of the subframe to reflect images produced by the projector. Access panels and cooling doors are provided in the carrying case to permit access and ventilation to the projector. The carrying case is provided with wheels to allow it to be rolled along the ground. The carrying case is also provided with offset handles on its sides so that the unit naturally tilts to aid in loading and unloading from raised surfaces.

  • Patent number: 6224774
    Abstract: The separation of a contaminant from a substrate that carries the contaminant is disclosed. The process comprises contacting the substrate to a carbon dioxide fluid containing an amphiphilic species so that the contaminant associates with the amphiphilic species and becomes entrained in the carbon dioxide fluid. The substrate is then separated from the carbon dioxide fluid, and then the contaminant is separated from the carbon dioxide fluid.
