Publication number: 20240133987Abstract: A system and method for L0 regularization-based compressed sensing (CS) may use a quantum-classical hybrid system consisting of coherent Ising machines (CIM) and classical digital processors CDP). The CIM and CDP each performs alternating minimization for L0 regularization-based compressed sensing (CS). A truncated Wigner stochastic differential equation (W-SDE) is obtained from the master equation for the density operator of the network of degenerate optical parametric oscillators.Type: ApplicationFiled: February 17, 2022Publication date: April 25, 2024Applicants: NTT RESEARCH, INC., TOKYO INSTITUTE OF TECHNOLOGYInventors: Toru AONISHI, Kazushi MIMURA, Masato OKADA, Yoshihisa YAMAMOTO

Patent number: 8938337Abstract: A laser sensor is located close to a rotation axis of a vehicle door and configured to emit a laser beam to a surface of the vehicle door and accept reflected light reflected from an obstacle for scanning a scanning plane shifted in a door-opening direction, in which the vehicle door is openable. A determination section determines whether an obstacle, which is possible to make contact with the vehicle door, exists in the door-opening direction of the vehicle door, based on a result of emission and acceptance of the laser beam of the laser sensor. An opening regulating section regulates an opening of the vehicle door in response to determination of the determination section that the obstacle exists.Type: GrantFiled: September 23, 2009Date of Patent: January 20, 2015Assignees: Denso Corporation, Nippon Soken, Inc.Inventors: Yohei Nakakura, Toshiyuki Konishi, Hideki Hioki, Yoshihisa Okada, Mitsuyasu Matsuura, Toshiki Isogai

Patent number: 8370021Abstract: A distance measuring sensor is arranged to a vehicle door, and measures a distance to an object in a direction corresponding to a scanning angle. A memory stores a standard angle and a comparison distance corresponding to the scanning angle. A distance-shortest scanning angle is defined by the shortest value of the measured distance. When the distance-shortest scanning angle is different from the standard angle, the scanning angle is corrected. The object is determined to be an obstacle having a possibility to contact with the door, when the measured distance is equal to or shorter than a corrected comparison distance corresponding to the corrected scanning angle.Type: GrantFiled: December 3, 2009Date of Patent: February 5, 2013Assignee: Denso CorporationInventors: Yoshihisa Okada, Toshiyuki Konishi, Hideki Hioki, Yohei Nakakura

Patent number: 8280593Abstract: A laser sensor projects laser light in the downward direction. If the laser sensor does not receive any laser light reflected by an obstacle or the ground, it is determined that the obstacle is present in the direction of projection of the laser light. It is thus possible to detect the presence of the obstacle, which will at least affect the opening of the vehicle door.Type: GrantFiled: March 2, 2010Date of Patent: October 2, 2012Assignee: Denso CorporationInventors: Yohei Nakakura, Toshiyuki Konishi, Hideki Hioki, Yoshihisa Okada

Patent number: 4921175Abstract: A food processor includes a main body with a graspable handle. A base plate is disposed in the main body. The base plate has a peripheral wall for defining a chamber. The peripheral wall has a discharge cutout along one circumferential part. A cover is removably placed over the base plate. A rotary blade supported on a driven shaft projects into the chamber between the cover and the base plate. An electric switch for the electric drive motor to the shaft includes a switch lever that pivots toward the main body to close contacts to the drive motor. A bar normally blocks for pivoting of the switch lever until the cover is placed on the base plate. The cover pushes the bar away from blocking the switch lever for enabling the switch lever to pivot to contact the contacts for activating the drive motor.Type: GrantFiled: September 1, 1989Date of Patent: May 1, 1990Assignee: Sanyei CorporationInventors: Yoshihisa Okada, Yoshihiro Enya

Patent number: 4921174Abstract: A food processor includes a main body with a graspable handle. A drive motor in the main body drives a shaft that projects up into a container and a rotor on the shaft processes food in the vessel. A cover removably disposed on the container is rotatable between an unlocked and a lockable position. An electric switch includes a switch lever pivotable up and down, and upon downward pivoting of the switch lever, the electric contacts to the motor are closed. A projection from the switch lever projects toward the body. A regulating member movable laterally of the body is contacted by the projection on the switch lever which prevents the switch lever from moving down. An operating piece projecting from the cover engages the regulating member and moves it out of the path of the projection. The operating piece on the cover has a cutout defined in it which receives the projection on the switch lever and enables the switch lever to be pivoted down to close the contacts.Type: GrantFiled: September 1, 1989Date of Patent: May 1, 1990Assignee: Sanyei CorporationInventors: Yoshihisa Okada, Yoshihiro Enya
