  • Publication number: 20230377481
    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.

  • Publication number: 20230252911
    Abstract: Disclosed is a Braille display with protection against the ingress of contaminants. In one embodiment, contaminant protection is provided by a flexible film that is secured beneath the Braille dots of the display. This film both secures the dots and prevents contaminants from coming into contact with pin actuators within the display housing. In another embodiment, ingress protection is provided by air pressure supplied to a plenum located at the base of the dot pins.

  • Publication number: 20100082535
    Abstract: A method and system is disclosed for receiving advertisement content files within a digital advertisement platform operating on a server computing system. Data defining a compressed file is received at the server. The compressed file includes a hierarchical structure of folders and a number of advertisement content files disposed within the hierarchical structure of folders. The hierarchical structure of folders is automatically extracted from the compressed file. The extracted hierarchical structure of folders is automatically created within a content library maintained within the digital advertisement platform. The advertisement content files are automatically extracted from the compressed file. The extracted advertisement content files are stored within the hierarchical structure of folders created within the content library so as to mirror disposition of the advertisement content files in the hierarchical structure of folders within the compressed file.

  • Publication number: 20090011391
    Abstract: An electromechanical relief display device comprising: a frame; at least one tactile member provided in said frame which is movable between at least a first position and a second position such that by feeling for said tactile member a user determines in which position said tactile member is; an oblong piezoelectric flexion member which may be bent (in a bending plane) under the influence of voltages applied thereto and subsequently flex back if these voltages are removed or if voltages with and inverted polarity are applied thereto; and supporting means for supporting said flexion member on said frame at two opposite sides of the flexion member wherein the flexion member comprises a contact-location which is coupled to the tactile member for moving the tactile member between the first and second position by bending or flexing back the flexion member, wherein the flexion member is a bimorph flexion member wherein the supporting means comprises at least a first and second supporting member for supporting the

  • Patent number: 6421011
    Abstract: A non-conductive frame supports the resonators in a patch antenna assembly. The frame supports the resonators without making holes in the resonators and thereby avoids the problem of creating unwanted electric field polarizations. Additionally, the frame grasps the resonators in areas of low current density and thereby avoids creating additional disturbances in the radiation pattern. The frames may also include posts that are used to attach the frames to the feedboard without using additional components such as screws.
