  • Publication number: 20080155501
    Abstract: Disclosed is a system for revising an electronic draft having a first format. This system includes an extraction unit adapted to extract a part of the data of the electronic draft requiring revision, a transformation unit adapted to transform the extracted data into a second format, a first transmitting unit adapted to transmit the transformed extracted data to a first viewing unit, wherein the first viewing unit is adapted to display the transformed extracted data and an input unit adapted to receive revising input for revising the displayed transformed extracted data. The system further includes an editing unit adapted to edit the transformed extracted data according to the revising input and a second transmitting unit adapted to transmit the edited transformed extracted data to a second viewing unit wherein the second viewing unit is adapted to display edited transformed extracted data wherein the first format is adapted such that the electronic draft can not be edited using the editing unit.

  • Patent number: 6781834
    Abstract: A cooling device with an air shower is disclosed. The cooling device includes a heat mass with a plurality of spaced apart fins connected therewith. An air shower including an injector face with a plurality of disrupter orifices is positioned over the fins so that the disrupter orifices direct a second air flow into slots between adjacent fins. A first air flow flowing through the slots is impinged upon and is disrupted by the second air flow resulting in the generation of turbulence in the first air flow. Consequently, a thermal boundary layer in the first air flow is disrupted and a rate,of heat transfer from the fins and the heat mass are increased.
