Abstract: Disclosed is an apparatus and method for combating light sensitivity, or photophobia, for people with low vision. Both the apparatus and method filter particular wavelengths of light associated with photophobia. This filtering is achieved while maintaining a luminance that is acceptable to the user and that maintains contrast. The apparatus of the disclosure is a mechanical filter that can be applied over an electronic screen. The method utilizes software and a filtering module associated with either the CPU or GPU of a computer. The filtering module processes a video signal by eliminating certain targeted wavelengths of light.

Abstract: Screen magnification software on a touchscreen device detects when a low-vision user reaches the boundary of a magnified viewport. If additional canvas or menus lay on the other side of the boundary the present invention enables the low-vision user to maintain the same exploration gesture on the touchscreen while causing the underlying canvas to scroll into view in the direction of the gesture. This invention enables the low-vision user to navigate about the entire underlying canvas of a touchscreen graphic user interface with a single, intuitive touchscreen gesture even under magnification.

Abstract: The present invention discloses methods of archiving and optimizing lectures, presentations and other captured video for playback, particularly for blind and low vision individuals. A digital imaging device captures a preselected field of view that is subject to periodic change such as a whiteboard in a classroom. A sequence of frames is captured. Frames associated with additions or erasures to the whiteboard are identified. The Cartesian coordinates of the regions of these alterations within the frame are identified. When the presentation is played back, the regions that are altered are enlarged or masked to assist the low vision user. In another embodiment of the invention, the timing of the alterations segments the recorded audio into chapters so that the blind user can skip forward and backward to different sections of the presentation.

Abstract: A hand held tape dispenser for applying adhesive tape to a surface. The dispenser includes a housing for holding and dispensing a roll of tape and has a tape dispensing opening therein. A plurality of rollers are within the housing, the outer surfaces of which coact with each other and the tape to retain, guide and feed the tape through the opening. The outer surface of at least one of the rollers protrudes through the opening on one side thereof enabling frictional contact of the roller with the surface to be taped. When the tape dispenser passes over the surface in one direction the outer surface of the roller engages the surface and the tape causing it to roll and to coact and drive the other rollers. This causes the rollers to grip the surfaces of the tape and feed the tape through the opening enabling the tape to adhesively contact the surface and adhere thereto. The tape is cut off at the opening.

Abstract: A tape dispenser for applying adhesive tape to a substrate surface. The dispenser includes an exterior application surface with an opening therein. A plurality of rotatable cylindrical rollers are mounted within the housing, wherein the surfaces of the rollers coact with each other and the tape surfaces to retain, guide and feed the tape through the tape dispensing opening to the exterior application surface. At least two of the plurality of rollers are opposed rollers that engage the tape surfaces therebetween. The outer surface of at least one of the plurality of rollers protrudes through the opening enabling frictional contact of the roller surface with the substrate surface. When the dispenser is drawn over the surface, the outer surface of the this roller engages and rolls over the substrate surface. It also coacts with the outer surfaces of the other rollers, causing them to grip the tape and feed it through the opening, enabling the adhesive tape to be applied to the substrate surface.

Abstract: A tape dispenser for applying adhesive tape to a substrate surface, the tape having a first surface with a pressure sensitive adhesive thereon and a second surface. The dispenser includes a housing suitable for holding and dispensing a roll of tape. The housing has an exterior application surface that has a tape dispensing opening therein. A plurality of cylindrical rollers are provided within the housing, each roller having an outer surface. The outer surfaces of the rollers coact with each other and the tape surfaces to retain, guide and feed the tape through the tape dispensing opening to the exterior application surface. The outer surface of at least one of the rollers protrudes through the application surface on one side of the opening enabling frictional contact of the roller surface with the substrate surface.

Abstract: A system and method for characterizing burst data in a communication network detects the occurrence of burst information and categorizes the burst information into at least one category based upon either bits or frames. Because one second time intervals may contain multiple categories of burst information, the analysis of which may overwhelm a network management system, the burst categorization logic of the present invention allows the capture and analysis of multiple burst categories in a single time interval over a long period of time, thereby allowing the analysis of a large amount of information without overwhelming a network management system with data.

Abstract: An apparatus for sealing bags having an open end and being particularly suited for packaging diapers. The apparatus having application in line with a diaper production and bag filling machine. The open end has a pair of horizontal lips and a pair of vertical lips. An infeed conveyor intermittently conveys each one of the bags in turn from an existing production line to a sealing station. In the sealing station, advancing means continuously advance the bags past an alignment section, a vacuum and side tucking section, adhesive application sections, and folding sections. The vacuum section holds the horizontal lips in an open position while the side tucking section tucks in each of the vertical lips to form side tucks and an upper and lower horizontal flap.
