    Poa sana liquidating trust

    A flat panel liquid crystal display (12) with an integrated touch panel has a multitude of pixels (28) arranged in multiple columns and multiple rows.

    The pixels (28) of the first column (54) and last column (66), and of the first row (60) and of the last row (72) are controlled in conjunction with emitters...

    The apparatus of claim 1 wherein the detection means includes a second reflection means for redirecting the light reflected by the reflection means toward a second column of elements, the second column of elements being controllable for assuming a transparent state and an opaque state, the light redirected by the second reflection means propagating through an element in the second column whenever that element is in the transparent state.3.

    The processing device is configured to determine a data entry to the touch screen by deciphering the coordinates of an interrupt in the light created in the free space adjacent the touch screen device when a data entry is being made to the touch screen device.filling the negative grooves with an optically transparent material and thereby optically coupling the plurality of optical elements and the plurality of grooves filled with the optically transparent material respectively., further comprising molding the waveguide substrate from a material having a first index of refraction and filling the grooves with the optically transparent material having a second index of refraction, wherein the second index of refraction is greater than the first index of refraction., further comprising molding the waveguide substrate such that the plurality of the negative waveguide grooves extend on a first surface of the substrate and a second surface of the substrate, wherein the first surface and the second surface are either perpendicular or parallel to one another., wherein molding the waveguide substrate further comprises molding the waveguide substrate into one of the following shapes: a one a straight substrate; square; L-shaped, rectangle, triangle, round, or an oval shape., further comprising connecting a processing device to the imaging device, the processing device configured to determine a data entry to the touch screen by deciphering the coordinates of an interrupt in the light created in the free space adjacent the touch screen device when a data entry is being made to the touch screen device., wherein the molding of the waveguide substrate further comprises molding the waveguide substrate using one of the following molding techniques: injection molding; compression molding; embossing; optical micro-molding.wherein filling of the negative grooves further comprises over-filling the grooves with the optically transparent material such that the optically transparent material has poor adhesion to said treated portion; and This application is a divisional application of and claims priority U. One conventional approach to providing a touch or pen-based input system is to overlay a resistive or capacitive film over the display screen. Foremost, the film causes the display to appear dim and obscures viewing of the underlying display.After the substrate is molded, the grooves are filled with an optically transparent material to optically couple and align the plurality of lenses and the plurality of grooves respectively. 4, 2004, which is incorporated herein in its entirety and for all purposes. Field of the Invention The present invention relates generally to light generation and reception for touch screen displays, and more particularly, to an inexpensive, simple to make, self-aligning molded waveguide array made of an optically transparent material that can be used to generate a grid or lamina of light and receive the light for detection with touch screen displays. Description of the Related Art User input devices for data processing systems can take many forms.In one application, the molded waveguide substrate is positioned adjacent a touch screen device. Two types of relevance are touch screens and pen-based screens.A method for adaptively fabricating a waveguide comprises: measuring misplacement of a photonic device relative to a substrate; generating computer readable instructions for using a plurality of graphics primitives to form the waveguide; and photocomposing the waveguide on the substrate in accordance...A method for adaptively fabricating a waveguide comprises: measuring misplacement of a photonic device relative to a substrate; generating computer readable instructions for using a plurality of graphics primitives to form the waveguide; and photocomposing the waveguide on the substrate in accordance with the computer readable instructions.A facet of the modulator is etched by reactive ion etching (RIE) which allows integration of the PEWE lens on a common substrate (14).The lens is manufactured using a polymer film on a dielectric cladding layer.The pixels (28) of the first column (54) and last column (66), and of the first row (60) and of the last row (72) are controlled in conjunction with emitters (52, 58) and detectors (64, 70) with associated mirrors (74, 80, 82, 84) to create a sequence of light beams that extend across the display panel (12) in both the X and Y directions.Whenever a stylus (86) is placed near the display panel, two orthogonal light beams are interrupted corresponding to the X and Y positions of the stylus (86) relative to the display panel (12).(b) emitter means associated with a first column of elements for projecting light toward those elements, the first column of elements being controllable for assuming a transparent state and an opaque state, the light propagating through any one of the first column of elements that is in the transparent state;2.After the substrate is molded, the grooves are filled with an optically transparent material to optically couple and align the plurality of lenses and the plurality of grooves respectively.In one application, the molded waveguide substrate is positioned adjacent a touch screen device.This section may be referred to as Polymeric Elongated Waveguide Emulating (PEWE) lens.In the exemplary embodiment the first optical component is a modulator (11), and the other optical component is an optical fiber (13).The fabrication relies on the remelt and reflow properties of polymer films to provide a smooth adiabatic mode contraction from a circular (optical fiber) mode (≈6µm in diameter) to a semiconductor mode (≈1µm) over a length of 250 µm.
