Latest Patents

One of Nakazawa's latest patents is titled "Methods and systems for selling voice data." This invention allows a voice expressed by a voice actor or actress to be electronized into voice data. The voice data and character data are stored in an associated relationship on a server device of an enterprise. A list of voice data stored in the server is sent to a user's information terminal over the Internet. Upon the user's request, the server selects the corresponding voice data and sells it to the user, along with image data of the character.

Another notable patent is for a "Data storage apparatus having volatile memory and nonvolatile memory." This invention enables data input from a key switch to be displayed on a liquid crystal display. Users can select whether to store the data in RAM or EEPROM using a selection switch. If EEPROM is chosen, a CPU activates a power switch to apply a high voltage to the EEPROM for data writing. The data stored in both RAM and EEPROM can be read out and displayed sequentially on the liquid crystal display, clearly indicating the source of the displayed data.
