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.
Abstract:
Disclosed is a magnifier that is adapted to rest upon a table. The magnifier includes an articulated camera arm that permits an associated camera to be pointed in a number of different directions. This permits the camera to focus upon, and enlarge, both distant and nearby objects. The magnifier also includes pivotal support legs. The legs have a first locked position to support the magnifier upon a table and a second position wherein the legs are locked in position adjacent the housing of the magnifier. This permits the magnifier to be readily transportable and stowable to accommodate the needs of the user.
Abstract:
Disclosed is a video processor for a magnifier camera. In particular, the disclosure relates to a video processor that eliminates the use of a frame buffer. This, in turn, reduces the latency otherwise present in the video signal. The disclosed video processor also allows selected portions of the display to be shaded. This highlights the non-shaded portions of the display while at the same time allowing the entire object to be perceived by the user.
Abstract:
A portable magnifier camera with an associated display housing, base and handle. The camera can be selectively positioned into a variety of configurations, including: a first closed configuration wherein the display and base are in facing relation; a second opened configuration wherein the display is angled with respect to the base; and a third hand-held configuration wherein a handle is pivoted outwardly to permit a user to hold the camera relative to a distant object. The angle of the camera adjusts automatically in each configuration to ensure that the camera's light of slight is perpendicular to the object plane. These configurations enable a user to effectively view objects of differing size and at varying distances.
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:
Disclosed is a portable magnifier camera with both storage and deployed configurations. In the storage configuration, the entire assembly can be carried via an associated handle. The camera is designed to rest on a desktop, or other planar surface, in the deployed configuration. When deployed, a housing and camera arm are positioned in a cantilevered arrangement over top of an object to be viewed. A camera housing, with an associated camera, is pivotally connected to the camera arm and is positioned over the object upon the camera being placed into a deployed configuration.
