Yutaka Uono 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).

  • Passenger protecting apparatus and method for protecting passenger
    Patent number: 7930080
    Abstract: A first control signal generating unit and a second control signal generating unit output a first control signal and a second control signal when magnitude of an impact corresponding to first and second sensor signals are greater than a first and second threshold. A third control signal generating unit outputs a third control signal when detecting disruption of the second sensor signal. An activating signal generating unit activates a protecting device when the first control signal is output, and when one of the second control signal and the third control signal is output. A fourth control signal generating unit outputs a fourth control signal when detecting an abnormality other than disruption of the second sensor signal. The third control signal generating unit restricts outputting the third control signal when the fourth control signal is output.

  • Vehicular occupant protection device
    Patent number: 7268445
    Abstract: An airbag device includes a squib, an ignition circuit, and a noise protection circuit. The noise protection circuit includes two zener diodes whose cathodes are facing each other and connected with each other. Further, the noise protection circuit is connected in parallel with the ignition element to thereby protect the ignition circuit from noise. This decreases the number of components in the noise protection circuit to thereby achieve the compact and low-cost airbag device.
