Latest Patents
One of Kitagawa's latest patents is a personal digital assistant that includes a loss detector. This device is designed to detect a lost state and retain a value assessment index, which consists of numerical values indicating data values. When a lost state is identified, the device determines a data recovery sequence based on these values and transmits the data to another terminal. The recovery sequence calculation takes into account the electrical energy required for data transmission, referencing a power consumption table and the remaining battery power level.
Another significant patent is a personal authentication system aimed at simplifying the authentication process when using information technology devices or cards. This system utilizes a combination of RFID tags worn by the user, which are stored during the authentication process. When authentication is needed, these RFID tags are detected again. The system allows for continuous use of previous authentication based on the degree of coincidence between detected RFID information and stored combinations. Additionally, it references a past archive to create an RFID list, calculating a weighted coefficient based on usage frequency to enhance reliability.
