Latest Patents

One of Okada's latest patents is a communication apparatus designed to improve the way users identify callers. Traditionally, when a mobile phone receives an incoming call that goes unanswered, users can only see the caller's name or number along with the time of the call in their call history. Okada's invention addresses this limitation by displaying an image of the caller after the call ends, allowing users to recognize who called them. Additionally, this apparatus shows the caller's image during call waiting, enabling users to identify the caller later.

Another significant patent is for a mobile terminal that efficiently handles message storage and duplication checks. This device receives messages transmitted via radio through the telephone network and stores them in nonvolatile memory. Upon energization, it calculates a checksum for the stored message and saves the result in RAM. When a new message is received, the checksum is compared with those stored in RAM. If a match is found, the messages are compared, and if they are identical, the new message overwrites the old one in nonvolatile memory. This innovation allows for quicker detection of duplicate messages.
