    摘要: The projector of the present invention provides a means for interactively displaying and annotating a document image at two separate locations. The projector consists of an image plate having an array of picture elements for displaying the image; a projection mechanism for projecting the image displayed by the image plate onto a projection screen; and a digitizer having a coordinate input array which corresponds to the array of picture elements of the image plate, wherein the image displayed by the image plate changes in response to coordinate inputs to the digitizer. A method for interactively annotating an image communicated between a remote and local image includes the procedure of simultaneously transmitting to the remote projector, annotations made to an image in the local projector.

    摘要: A polarization converter for polarizing a light beam by converting all light waves to the same orientation comprises 1) a first beam dividing matrix of refractory material for dividing a single, large light beam into smaller sub-beam 2) a second beam focusing matrix for polarizing select portions of the sub-beams, and 3) a series of narrow and shallow polarizing cells. The second beam focusing matrix further comprises a plurality of concave lenses for redirecting each sub-beam and quarter wave retarders disposed in alignment with, and adjacent to, the reflective side of an equal plurality of mirror segments. The polarizing cells include either a first beamsplitter or a second beamsplitter, where the first beamsplitters and second beamsplitters are disposed in opposing diagonal fashion and in an alternating manner. Lightwaves of a selected polarization pass directly through the first beamsplitter and out of the polarizing cell, while all other lightwaves are horizontally reflected by the first beamsplitter and directed onto the second beamsplitter where they are redirected toward the quarter wave retarder. The reflected light passes through the quarter wave retarder, reflects off of the mirror and again passes through the quarter wave retarder. The wavelength of the light is retarded ninety degrees as a result of the two passes through the quarter-wave retarder, thus re-orienting the light to the selected orientation. The re-oriented p-waves pass through the second beamsplitter and exit the polarizing cell, join the original p-waves exiting the polarizing cells, and form a beam of polarized light.

    摘要: An apparatus and method for detecting the presence of ringer signals in a telephone which samples the incoming telephone signals within a prescribed time interval, windows the signals, and computes a set of auto-correlation coefficients. These coefficients are normalized, and their absolute values are calculated and summed and compared with an empirically-derived threshold. If the coefficient sum exceeds the threshold, a high degree of correlation within incoming signals is indicated, distinguishing the incoming signal as containing ringer signal constituents.

    摘要: A polarization converter polarizes an incident light beam having a first component with a first plane of polarization and a second component with a second plane of polarization orthogonal to the first plane. The polarization converter comprises a planar matrix for concentrating and collimating the incident light beam; a polarizer parallel to the planar matrix for refracting the first component and reflecting the second component; quarter-wave retarding means, parallel to the planar matrix and disposed between the planar matrix and the polarizer, for delaying the second component one-quarter wavelength relative to that of the first component; and reflection means, between the quarter-wave retarding means and the planar matrix, for reflecting the second component back through the quarter-wave retarder. The planar matrix may include on a top surface an array of first lenses and on a bottom surface an array of second lenses. The first and second lenses operate jointly to concentrate and collimate the incident light beam. The polarizer divides the concentrated light beam based on their planes of polarization into the first and second components, thereby enabling the quarter-wave retarder and the reflection means to orient only the second component to match the orientation of the first component.
