    摘要： Catadioptric area-of-interest display projectors produce displays having resolution of substantially less than 10 arc minutes per line over a wide field of view. Such projectors include an external entrance pupil for receiving images of substantially collimated light, and optics for conveying such light onto and through an opening in the surface of an aspheric mirror, and then through an opening in a spherical mirror so that light emerging from the opening in the spherical mirror is displayed on a curved screen surface with such high resolution.A projector system includes this projector and a mirror for steering collimated light from the entrance pupil of the projector into the projector optics. This system, when placed in a flight simulator at the periphery of a flight simulator dome for projection of such light images onto the inner curved surface of the dome, provides high resolution images to viewers located at the center of the dome.

    摘要： A system and a method for the transmission and reception of digital data wirelessly using acoustic tones comprises a device having an encoder, a modulator system, a demodulator system, and a decoder. The modulator system uses dual tone multiple frequency (DTMF) tones that are amplitude modulated. The received signal is demodulated and detected by Fourier analysis. An expanded Hamming code based decoder is used for correcting errors occurring during transmission.

    摘要： An improved computer graphic work station is disclosed of the type that includes a digitizer for allowing an artist or other user to input a drawing into a computer, and an imaging device to produce an image of the drawing as it is being drawn. A beam splitter reflects at least a portion of the produced image to the eye of the user. The position and orientation of the beam splitter may be varied by a user relative to the imaging device in order to allow the user to align the workstation by causing the reflected image to appear, in the user's eye, to be substantially coincident with the drawing. Once aligned, the user may adjust the position and orientation of the digitizing surface without upsetting the alignment.

    摘要： An optical virtual touch pad system wherein reflective optics are used to superimpose a virtual image of a television screen display onto a touch-sensitive digitizing surface being operatively contacted by a user-controlled contact member. Alternatively, the system uses reflective optics to superimpose an uninverted virtual image of the digitizing surface and the contact member operating thereon onto the surface of the display. The system thereby, for example, can be used as a user interface to control interactive content on a home television.

    摘要： A special effect system and method includes an image panel having a surface coated with phosphor particles and a video screen that projects a transmitted predetermined display. The phosphor coated surface of the image panel is placed in close proximity to the video screen. The phosphor particles that overlap and are thus exposed to the predetermined display are excited by the wavelength emissions of the display and undergo phosphorescence in a wavelength range of human-visible light. Thus, when the panel is removed from the screen, a glow in the dark, "secret" message or image, special effect is revealed.
