Patents by Inventor Kentaro Todoroki

Kentaro Todoroki 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: 10605906
    Abstract: A sanitary device includes a radio wave sensor, a control section. The radio wave sensor is configured to obtain information on a sensing target by a reflection wave of an emitted radio wave. The control section is configured to control operation of an instrument based on a sensing signal including a first signal and a second signal outputted from the radio wave sensor. Difference between a phase of the second signal and a phase of the first signal is not less than 60° and not more than 120°. The control section is configured to determine presence or absence of the sensing target based on sum of square of difference between a value of the first signal and a first reference value and square of difference between a value of the second signal and a second reference value.

  • Patent number: 6948194
    Abstract: An object of the present invention is to provide a toilet cleaning device which is capable of cleaning a toilet stool by supplying cleaning water in an appropriate quantity corresponding to the state of usage by a user, which is provided with a self-diagnosis function for diagnosing cleaning water stoppage or the like, and which has a simple constitution so that maintenance can be performed easily. The output of a Doppler sensor 11 is amplified by an amp 31, and a frequency spectrum is determined by an FFT calculation portion 32. A flow rate is determined by conversion in a flow rate calculation portion 33 on the basis of the frequency spectrum. A controller 34 operates other devices on the basis of the flow rate calculated by the flow rate calculation portion 33 and the operational state of a cleaning instruction button 16. Cleaning water supply valve 36 is opened and closed in accordance with instructions from the controller 34.

  • Patent number: 5735798
    Abstract: A toilet-installed digital sphygmomanometer provided with retractable cuffs. A housing (36) is arranged laterally of a toilet seat and two occluding finger cuffs (62) different in size are mounted to associated respective sliders (70) in a manner movable relative to the housing (36). In use, one of the sliders is moved to permit a cuff (62), of a size suited to the size of the user's finger, to protrude out of the surface of the housing (36) for engagement by the finger. When not in use, all the cuffs are retracted within the housing so that the cuffs are kept clean. In another embodiment, a plurality of pivoting arms are hinged to the housing and the cuffs different in size are mounted, respectively, to the associated pivoting arms. In still another embodiment, a plurality of cuffs different in size are mounted to a revolving member journaled to the housing and a particular cuff is selected by rotating the revolving member.
