Latest Patents

One of Endo's latest patents is the "Programmable television game and training system with adaptable operator." This invention features a television-connected microprocessor system designed primarily for use as a television game or educational system. The system accepts source programming from interchangeable cartridges, which utilize either ROM or RAM to store the source programming. The source program is stored in a higher-level language, such as BASIC, and is interpreted for use by the microprocessor. Each ROM cartridge includes a keyboard entry device that is uniquely adapted to the programming in the cartridge, allowing users to engage with the games or training sequences effectively. Additionally, by using a RAM cartridge, users can enter their own source programs via a general-purpose keyboard or tape recorder, with keyboard overlays adapting the keyboard to the specific game or training sequence.

Another significant patent is the "Color pattern and alphanumeric character generator for use with raster-scanned CRT display devices." This invention simplifies the apparatus used for generating color background patterns and characters in an integrated manner. The viewing area of the raster-scan CRT is divided into a matrix of character cells, each further divided into color cells. A display RAM, addressed by a microprocessor, stores display information, allowing for a more complex and easily varied color pattern display than previously possible.
