    Abstract: A device that enlarges text and images to enable a low vision person to see the text and images includes a hollow structure including a top housing and a bottom housing that are connected to one another. A camera aperture is formed in the bottom housing and a transparent light guide lens is disposed in closing relation to the camera aperture so that all light entering the camera aperture must first pass through the light guide lens. A cavity formed in the light guide lens is bounded by walls that are positioned at a critical angle. Light-emitting diodes are positioned at critical locations about the periphery of the light guide lens to illuminate the object being viewed.

    IPC: G09B21/00

    CPC classification number: G09B21/003

    Abstract: Disclosed is a Braille display device. The device supports an array of individual Braille cells with corresponding tactile pins. The pins can be selectively lifted by way of reeds to generate Braille characters that can be felt by the user. The Braille characters can correspond to visible characters, such as characters on a computer screen. The display is refreshable to allow for the sequential display of lines, paragraphs or pages. In accordance with the disclosure, the Braille cells are constructed in a manner that minimizes manufacturing costs and that also permits the size of the display to be greatly reduced.

    Abstract: Systems and methods for imaging objects are provided. An imaging device includes a sensor to provide an image of an object. The sensor can have a sensor exposure time and a sensor gain and the image includes a plurality of frames, each of the plurality of frames that can depict at least a portion of the object. The imaging device includes a motion detector to determine whether there is movement of the at least a portion of the object between adjacent frames of the plurality of frames. The imaging device also includes a controller. The controller can set the sensor exposure time to a first value in response to a determination by the motion detector that there is movement of the at least a portion of the object between adjacent frames. The controller can also set the sensor exposure time to a second value in response to a determination that there is no movement of the at least a portion of the object between adjacent frames. The controller can also adjust the sensor exposure time, the sensor gain, or both to maintain a luminance value of the plurality of frames at a target luminance value.

    Abstract: Disclosed is a braille display that is impact resistant and that employs a modular construction. The impact resistance is achieved, in part, by molded and resilient end caps. Each end cap includes a centrally positioned slit that functions in absorbing lateral impacts to the display. The impact resistance is further achieved by an over molded housing that is positioned about an associated USB connector. The modularity of the display is achieved by way of a subassembly that is releasably secured within the interior of a main housing. The subassembly, in turn, includes a series of cell compartments that are arranged in groups. Each group of cell compartments is controlled by an individual shift register. This allows a grouping cell compartments to be removed and replaced as needed without disturbing the remaining cell components.
