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 translation: 盲文显示装置。 该设备支持具有相应触觉引脚的单个盲文单元阵列。 可以通过簧片选择性地提升销，以产生用户可以感受到的盲文字符。 盲文字符可以对应于可见字符，例如计算机屏幕上的字符。 显示屏可以刷新，以便顺序显示行，段落或页面。 根据本公开，盲文单元以最小化制造成本并且还允许显着减小的尺寸的方式构造。

Abstract: The present disclosure relates to a vision assistive device for use by blind or low vision users. The device includes an imaging unit for viewing objects positioned beneath the device. The device further includes a forwardly facing screen for displaying an enlarged view of the imaged object to the user. The imaging unit is configured to take multiple views of the object, each with a different area of focus. This can be accomplished by digitally changing the imaging sensor's area of focus or by pivoting the sensor via a focus motor. In either event, the resulting images are combined into a single, integrated, focused, and composite image. Combining images with differing areas of focus helps eliminate any blurry regions in the composite image. The device further includes a rearwardly positioned fin that facilitates positioning the device in multiple different orientations. In a first orientation, the device is vertically positioned upon a desktop. In a second orientation, the device is reclined and placed in the user's lap with the fin positioned between the user's legs.

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 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.

Abstract: Disclosed is a magnification device with multiple orientations. This allows a blind or low vision user to select the best orientation for the task being performed. The device includes both opened and closed orientations. It is further configurable into document reading, near object inspection, far object inspection, and self inspection modes. The camera of the device can be manipulated by the user depending upon which of these orientations is selected. Furthermore, the camera automatically adjusts itself into one of two pre-set configurations whenever the device is opened or closed.
