Publication number: 20230377481Abstract: 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.Type: ApplicationFiled: August 1, 2023Publication date: November 23, 2023Inventors: Patrick Murphy, Todd Conard, Bradley S. Davis, Maarten van Egmond

Publication number: 20230252911Abstract: 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.Type: ApplicationFiled: February 9, 2022Publication date: August 10, 2023Inventors: Todd Conard, Walter van Tujil, Patrick Murphy, Maarten van Egmond

Publication number: 20100082535Abstract: 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.Type: ApplicationFiled: September 30, 2008Publication date: April 1, 2010Applicant: Yahoo!

Patent number: 6421011Abstract: 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.Type: GrantFiled: October 22, 1999Date of Patent: July 16, 2002Assignee: Lucent Technologies Inc.Inventors: Maarten Van Egmond, Keith V.
