Abstract: A power generating apparatus for fluid flow conduits where the apparatus includes an impeller positioned in the path of the fluid flow. The impeller is either directly or magnetically coupled to an electric generator outside of the fluid flow conduit. As the fluid flows it causes the impeller to rotate thus causing the electrical generator to turn and thereby produce electricity. This can then be used to power various devices or to trickle charge batteries. The fluid flow conduits may be common commercial or domestic water pipes or other systems such as solar water heaters and distillation devices.

Abstract: The present invention relates to an image projection device of the type playing images receive via remote means or read from a stored data media. When a mobile phone, the device includes an image projection capability in addition to the standard display. Both the display and the image may be the same or may differ according to the user requirements. The device may also be a smart card or compact disc player that projects an image of the data. The device may further still include a camera to record an image and in the case of a mobile phone transmit it to another receiver. This allows the use of mobile phones for video conferencing.

Abstract: The present invention relates to a video projector (10) including a housing (18) and an optical engine (40) located therein for projecting an image onto a distal surface. The optical engine (40) includes a liquid crystal display (LCD) projector and further includes an objective lens (38) to focus the image. Such a configuration makes the projector (10) ruggedised in that the optical engine (40) securely holds all of the components necessary to project an image, including the objective lens (38). Furthermore, there exists a channel (42) between the optical engine (40) and the housing (18) which, together with a fan (58) and two strategically positioned cooling vents, allows for the optical components located within the optical engine (40) to be sufficiently cooled. The projector (10) operates through the use of a cooled transformer located in a base (12) which converts mains input, typically 240/110 V, to 12 V.

Abstract: An apparatus for the display of geographical information comprising a remote communication device having a display and a global positioning system adapted to provide information about the position of the device and transmit it to a remote location; and a remote database having geographical data, wherein the communication device transmits its current position to the database and the database transmits geographical information in relation to that position to the communication device, the information subsequently being displayed on the communication device display.
