Patents by Inventor Kaoru NAKAGAKI

Kaoru NAKAGAKI 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: 11307304
    Abstract: An object detection device includes: first and second transmission/reception units transmitting and receiving an exploration wave to detect a peripheral object; and a processing unit determining a position of an object based on reception results of the first and second transmission/reception units. The processing unit calculates a first point based on first and second exploration waves, calculates a second point based on third and fourth exploration waves, determines that the object exists on a line segment interconnecting the first and second points when a distance between the first and second points is less than a predetermined value, and determines that the object exists on the line segment and line segments extended from both ends of the line segment when the distance between the first and second points is equal to or greater than the predetermined value.

  • Patent number: 11294053
    Abstract: An object detection device includes: first and second transmission/reception units spaced apart from each other and configured to transmit an exploration wave and receive the exploration wave reflected by an object; and a processing unit configured to calculate a position of the object based on reception results by the first and second transmission/reception units. The processing unit includes: a distance processing unit configured to calculate first and second points based on the reception results, and calculates a separation distance between the first and second points; a position calculation unit configured to calculate the position based on the first and second points; a reflection intensity processing unit configured to calculate a reflection intensity indicating an intensity of the exploration wave received by the first and second transmission/reception units; and a position correction unit configured to correct the position based on the separation distance and the reflection intensity.
