    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: 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.
