International Classification:

G02B 27/02

US Classification:

362 97, 362 98, 349200, 359802

Abstract:

A box-like illuminator includes a top wall having a flat sheet of clear material through which an illuminated image is viewed. A bottom wall of the illuminator is also formed of a flat sheet of clear material and is positioned atop the object to be illuminated. Light from an LED is directed in a first, downward direction onto a deflection wall where it is deflected into a substantially horizontal plane, substantially orthogonal to the first direction. The deflected light impinges upon a horizontally-disposed diffuser that bends the light about ninety degrees so that it travels though the diffuser a first time in a first direction and illuminates the object atop which the illuminator is positioned. The light is then reflected by the object, travels upwardly through the diffuser a second time in a direction opposite to the first direction, and is viewed by the user through the clear material.

International Classification:

US Classification:

362 97, 362 98, 349200, 359802

Abstract:

A magnifier for use by people with low vision includes a large LCD display upon which an enlarged image appears. Light from an LED is directed in a first direction onto a deflection wall where it is deflected into a direction substantially orthogonal to the first direction. The deflected light impinges upon a diffuser that bends it so that it illuminates an object upon which the magnifier is placed. The light is then reflected by the object, through the diffuser, and onto a mirror positioned at an angle relative to the object. The mirror directs the light onto a camera lens and the lens focuses the light onto a sensor that drives the LCD display so that the image appears on the LCD screen. The camera is slideably mounted so the user can make the image larger or smaller by sliding the camera toward or away from the mirror, respectively.

International Classification:

G08B 522

US Classification:

34082544

Abstract:

A selective call device (130) has a receiver (204) for receiving information at a first rate and a switch (229, 230) for selecting a streaming mode for providing the information. A processor (210) for determining when the streaming mode is selected, and in response thereto, creates a buffer (221, 222) for retaining the information. The processor (210) transfers the information from the buffer (221, 222) at a second rate for a display (228) to present the information that is transferred from the buffer (221, 222) as a continuous stream.

International Classification:

G09B 21/00
G09B 21/02
G06F 3/01

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.
