  • Wavelength conversion film, light-emitting member, authentication device, wristband type electronic apparatus and biometric device
    Patent number: 11774653
    Abstract: Disclosed is a wavelength conversion film including at least two or more dyes and absorbing irradiation light to emit light at a longer wavelength than that of the irradiation light. The wavelength conversion film includes a first dye having a maximum absorption wavelength in a red light region, and a second dye absorbing excitation energy of the first dye to emit light in a near infrared region.
    Type: Grant
    Filed: January 16, 2020
    Date of Patent: October 3, 2023
    Assignee: KONICA MINOLTA, INC.
    Inventors: Mio Watanabe, Kenichi Tabata, Ryo Nakabayashi, Yasuo Miyata

  • Work machine, management system and management method
    Patent number: 10541875
    Abstract: A work machine includes: an electronic device; a signal line to which the electronic device is connected; a memory unit which stores at least identification information for identifying the electronic device; a communication unit which wirelessly communicates to an outside of the work machine; and a processing unit, wherein when the identification information acquired from the electronic device via the signal line is different from the identification information stored in the memory unit, the processing unit stores the identification information acquired from the electronic device in the memory unit and transmits the acquired identification information to the outside of the work machine via the communication unit.
