Abstract: A touch-screen device includes a radiation source, a pliable waveguide configured to receive radiation emitted by the radiation source and to cause some of the received radiation to undergo total internal reflection within the pliable waveguide, a frustrating layer disposed relative to the pliable waveguide so as to enable the frustrating layer to contact the pliable waveguide when the pliable waveguide is physically deformed, the frustrating layer being configured to cause frustration of the total internal reflection of the received radiation within the pliable waveguide at a contact point between the frustrating layer and the pliable waveguide when the pliable waveguide is physically deformed to contact the frustrating layer such that some of the received radiation undergoing total internal reflection within the pliable waveguide escapes from the pliable waveguide at the contact point, and an imaging sensor configured to detect some of the radiation that escapes from the optical waveguide.

Abstract: A method and apparatus is provided in which a digital image is transmitted to a presentation projector resource over a wireless transmission medium using a reduced amount of bandwidth by transmitting a subset of the digital image data. The subset of image data may be a delta subset that represents those areas of the image that have changed since the previous transmission. The subset image data may also be a scalable vector graphics representation of the subset of the digital image. A projector discovery logic selects a suitable projector resource based on the order or signal strength of the discovery replies. A wireless image transmission session is established with the selected projector resource during which the projector is unavailable to other devices. The subset image data may be compressed and transmission coordinated with the projector resource so that the data is sent only when it is ready to be received.

Abstract: A projection system including at least a laser light source, an image generator, a projection lens assembly, and a despeckling device. The image image generator modulates laser light from the laser light source to form a projection image. The projection lens assembly is positioned downstream of the image generator and projects the projection image. The despeckling device limits laser speckle of the projected projection image.
