Latest Patents
One of Okamura's latest patents is a coding equipment that provides compressed code. In this invention, a parallel digital signal delivered from an AD converter detects the '1' appearing in the bit position nearest to the most significant digit (MSD). This parallel digital signal is then converted into a serial digital signal, which consists of a weight character indicating the specific bit position and a data character indicating the numerical value of the data. Additionally, a weight bit is provided to change the weight of the output of the AD converter based on the analog quantity subjected to AD conversion, thereby reducing the number of bits required for coding the parallel signal.
Another significant patent is a protective relaying system designed to protect an electric power system under the control of a digital computer. In this system, the voltage and current of the electric power system are sampled at a predetermined frequency and converted into digital signals. The computer computes the product of these two digital signal inputs, which is then added to a preceding signal representing the product of voltage and current taken at a previous time. This process helps to remove unnecessary frequency components from the signals. The level of the resultant signal is compared with a reference signal, and if it exceeds the reference, necessary protective measures are taken to safeguard the electric power system.
