Patents by Inventor Yasuyuki NANAUMI

Yasuyuki NANAUMI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11853736
    Abstract: Ensuring that a control program of a programmable electronic component included in an optical module updatable as well while a control program of a microprocessor included in the optical module is in operation. A module that functions by causing an electronic component to operate, a microprocessor located in the module and coupled to a host device via communicating device uses data in the S-record format downloaded from the host device using the communicating device to update a control program of the electronic component.
    Type: Grant
    Filed: September 2, 2019
    Date of Patent: December 26, 2023
    Assignee: NTT ELECTRONICS CORPORATION
    Inventors: Yasuyuki Nanaumi, Atsushi Kusayama, Kiyoshi Kido, Yuji Akahori
  • Patent number: 11333950
    Abstract: An optical module of a configuration that ensures use of commercially available electronic components and reduction of the number of current generation circuits and electric wirings. The optical module includes an electronic component mounted on a separate board from a light wave circuit board provided with an optical component such as an optical switch, and they are each electrically connected by wire bonding. For this reason, the optical module can use a commercially available electronic component. In addition, the module has a configuration in which heaters of optical switches, which do not simultaneously flow currents, are grouped and a current from one current generation circuit is supplied to any one of the heaters in the group by means of one electrical switch. For this reason, the optical module does not have to be prepared with the same number of electrical switches and current generation circuits as the number of heaters.
