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 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 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: 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.

Abstract: A weft supply system for a loom having a support frame with vertically extending support beams interconnected with substantially horizontal and vertically separated rods which form a plurality of vertically aligned creel support levels. Creel mounting means are provided on an upper surface of certain of the horizontal rods and a multi-bobbin creel is mounted by each of the creel mounting means. The weft yarn supply system includes yarn delivery apparatus associated with each creel support level. The yarn delivery apparatus includes a pneumatic threading system for threading the weft yarn through the yarn delivery apparatus.

Abstract: A holder (18) for receiving and frictionally securing a yarn package (12) wound onto tubes of various inner diameters. The holder comprises a base support which includes an arm (20) adapted to be attached to a textile machine. Extending at a right angle from the base arm is a cantilever contact are (24) which is rigidly connected to the base. The contact arm has a contoured support arm (28) pivotally connected to its free end and extending alongside the contact arm to a point near the base support which is biased outward by a spring (34). A second embodiment (118) has two contoured support arms, one (128) of which is pivotally connected to the contact arm (124) at a point (127) intermediate a free end portion. A resilient second contoured support arm (143) is affixed to the end of the contact arm and has a portion which extends generally transverse over the longitudinal axis of the contact arm.

Abstract: A holder (18) for receiving and frictionally securing yarn package (12) wound onto tubes of various inner diameters is disclosed. The holder comprises a base support which includes an arm (20) adapted to be attached to the textile machine. Extending at a right angle from the base arm is a cantilever contact arm 24 which is rigidly connected to the base. The contact arm has a contoured support arm (28) pivotally connected to its free end and extending alongside the contact arm to a point near the base support. A spring (34) is interposed between the contact arm (24) and the contoured support arm (28) and urges them apart, and against the inner walls of a yarn tube (13) placed about the contact arm and the contoured support arm.

Abstract: A yarn package holder device (10) is disclosed which includes a bracket plate (12) adapted to be mounted to a supporting structure (14). A circular cam (A) is rotatably journaled in the bracket plate and is eccentrically connected to a shaft (24) having a remote end affixed to an actuator lever (30) and handle (32). The actuator lever rotates the cam (A) and moves a cam surface (22) in an eccentric path. On the eccentric path, the cam surface (22) includes a lock position with the actuator lever (30) in a down set position. Lifting the actuator lever from the down set position quickly releases the cam lock provided between the cam surface (22) and a ribbed clamping surface (34) permitting rapid removal of an empty tube (38) from which a yarn package (40) has been withdrawn.
