Abstract: An electrical generator, comprising a rotatable impeller locatable within a flow path of a conduit. The impeller is rotated by fluid flowing along said flow path. The impeller comprises a magnetic portion, the generator further including a stator located external of the flow path. The stator generating electrical power in response to rotation of the magnetic portion.

Abstract: An image projector assembly including a mountable image projection device and a docking station adapted for mounting said device. The image projection device is the optical engine and typically includes an image generating apparatus and a light source to project through said apparatus to thereby provide for an image. The docking station includes a signal generating apparatus to provide a signal to the image generating apparatus representative of a visual image and includes a power source for the optical engine. The demountable aspect of the assembly provides for easy replacement and maintenance of the optical engine as well as its portability to use in different optical engines thereby saving on cost.

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.

Abstract: A personal entertainment unit including a chair having at least one arm within which is housed a projector. The arm includes a door enabling an image to be projected from the projector outside of the arm. The door, when closed, hides the projector from view. Alternatively, the door may be located on top of the arm and a periscope configuration is used to project the image upwardly and then horizontally from the arm to be displayed on a surface. The door is generally electrically driven and, when in a closed position, is flush with the upper surface of the arm.

Abstract: An image projecting system for mounting in a hidden location such as a ceiling or a piece of furniture such as a desk. The system includes an image producing apparatus and a plurality of optical components. At least one of the optical components is a mirror that can move between two positions. In the first position the mirror is flush with the ceiling or the desk so that the system is hidden from view. In the second position the mirror is at an angle to the ceiling or the desk so as to project an image externally of the hidden location and onto a screen or other surface.

Abstract: A dual image displaying apparatus (10) is disclosed including a first light source (12) for emitting light through a first image (14) onto a surface and a second light source (20) for emitting light through a second image (22) onto the same or another surface. The first image may be produced by a slide whilst the second image is produced by a display receiving and converting electrical image information into the second image. Typically, this is a liquid crystal display (LCD). The apparatus further includes a plurality of filters and other optical components (16, 24, 30, 32) to assist in producing a good quality image as well as protecting the LCD. Instead of a slide, the first image may also be produced by an LCD.
