Abstract: The present invention relates to an interactive touch system on a transparent medium and more particularly, the present invention relates to a method and system for improving the contrast of writing on an interactive touch system on a transparent medium. The interactive device has an interactive surface having an interior side and an exterior side. The interior side is observed by at least one emitter and at least one detector. The interactive surface has a privacy layer; the privacy layer transforming between a transparent and a non-transparent state. A processing structure executing instructions detects a pointer contacting the interior side of the interactive surface; and applies a signal to the privacy layer to transform the privacy layer into the non-transparent state.

Abstract: An interactive board comprises an interactive surface; at least one user selectable element; and processing structure in communication with at least one imaging device and configured to process data received from said at least one imaging device to locate at least one pointer positioned in proximity with said interactive surface and update digital ink according to pointer location, said processing structure being further configured to send said digital ink to one or more devices in communication with the interactive board in response to selection of said at least one user selectable element.

Abstract: An interactive input system comprises at least one imaging device having a field of view looking into a region of interest. At least one radiation source emits radiation into the region of interest. A pliable bezel at least partially surrounds the region of interest. The pliable bezel has a reflective surface in the field of view of said at least one imaging device.

Abstract: A system for providing a portable touch system comprises a bezel having a first and a second end, and a housing that is adapted to receive the first and second end of the bezel such that a display area is bounded by the housing and the bezel. At least one camera system is coupled to the housing and is operable to capture within at least a portion of the display area images of an object located within a field of view of the at least one camera system.

Abstract: A display panel for an interactive input system comprises first and second touch surfaces on opposite major sides thereof and a touch detection arrangement to detect touch input on one or both of the touch surfaces.

Abstract: A method for preparing a substrate having an adherent, durable, flexible, and stain resistant layer. The layer is formed by applying a composition that includes (i) the reaction product of a polyester and a polyoxetane having at least one carboxylic acid end group and at least one pendant —CH2—O—(CH2)n—Rf group and (ii) an amino resin curative. The substrate may be printed or embossed or both. The coated substrate has both stain resistant properties and dry erase properties.

Abstract: A method of calibrating an interactive input system comprises receiving images of a calibration video presented on a touch panel of the interactive input system. A calibration image is created based on the received images, and features are located in the calibration image. A transformation between the touch panel and the received images is determined based on the located features and corresponding features in the calibration video.

Abstract: A touch panel for an interactive input system and interactive input system incorporating the touch panel is provided. The touch panel includes an optical waveguide layer and a resilient diffusion layer. The resilient diffusion layer is against the optical waveguide layer and causes light traveling within the optical waveguide layer to escape only when compressed against the optical waveguide layer at one or more touch points.

Abstract: A reactive fluorinated polymer having polyester and polyether segments is mixed with a reactive melamine resin to form a coating composition. The polyether segment can include monomeric units from an oxetane monomer having pendant fluorine groups that are linked to the oxetane via an ether group. The melamine resin can be a lower alkyl etherified melamine-formaldehyde. The composition can be disposed on a substrate and treated to form a laminate.

Abstract: A polyester polymer includes at least one hydroxyl terminated polyoxetane block containing repeat units derived from polymerizing at least one oxetane monomer having a pendant —CH2—O—(CH2)n—Rf group wherein said Rf group is partially or fully fluorinated. A preferred process for forming said polymer is by reacting a hydroxyl terminated polyoxetane with a polycarboxylic acid under appropriate conditions to form an ester linkage and then adding and reacting that product with polyester forming reactants. The polyester polymer containing at least one polyoxetane block therein when reacted with an amino resin curative can be used as a coating on a substrate wherein the coating has dry erase properties. The coated substrate can be used as prepared or applied to yet other substrates.

Abstract: The present invention involves a system and method which allows a sponsoring organization access to a physician's prescription process. The system electronically processes prescriptions via a personal digital assistant (PDA). First, the physician is provided with a PDA for generating prescription. The PDA transmits the prescription data over a network. A sponsor finances the PDA use and has the ability to direct messages to the physician on the PDA.
