Latest Patents

One of Black's latest patents is the "High-speed magnetic encoding apparatus and method." This invention involves an apparatus designed for high-speed bulk magnetic encoding of lottery tickets. It features a web of tickets that passes by an encoding apparatus, which supports multiple skates equipped with wheels or rollers. These skates maintain a controlled gap between the web and a magnetic write head. Additionally, each skate includes a magnetic read head and an inkjet print head. After the encoding and printing processes, the perforations in the web are burst, and the web is sliced into individual magnetically encoded lottery tickets.

Another significant patent is the "Optical card reader utilizing area image processing." This optical card reader is designed to read marks made on the face of a preprinted card. It utilizes a video camera and a memory device to capture and store an image of at least a portion of the card. The card features printed positioning indices, and the reader contains stored information defining possible locations of valid marks relative to these indices. The centroids of the positioning indices are determined to define potential locations of valid marks. The densities and centroids of the marks located in these areas are analyzed to ascertain the presence of a valid mark.
