Latest Patents
One of Maruyama's latest patents is the Asynchronous Delay Circuit. This invention employs a flip-flop circuit of the latch type to store logical values from two transmission lines. The circuit is designed to activate only when it is in an empty state, ensuring that the logical values of the outputs are coincident. The flip-flop can be constructed using either two NOR circuits or two NAND circuits. Additionally, multiple asynchronous delay circuits can be connected in a cascade arrangement to form an elastic store, enhancing the functionality of the system.
Another significant patent is the Picture Signal Transmission System. This system is designed for transmitting coded picture signals obtained from scanning images. It detects the difference between the representative level value of each picture element and a forecast value based on adjacent elements. The system transmits first level information, indicating whether the difference exceeds a predetermined threshold, and second level information, which provides details on specific picture elements that exceed this threshold.
