Patent number: 11395067Abstract: A microphone-loudspeaker integrated apparatus includes a plurality of microphones, a loudspeaker, and a synthesis unit. The loudspeaker is disposed between the plurality of microphones. The synthesis unit synthesizes sounds collected from the plurality of microphones. A distance between the plurality of microphones is set so as to fall within a range within which sound at a frequency needed for recognizing voice is collectable and within a range within which a noise amount due to vibration of the loudspeaker is allowable, when voice recognition is performed based on sound obtained through synthesis by the synthesis unit.Type: GrantFiled: March 18, 2019Date of Patent: July 19, 2022Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATION, YAMAHA CORPORATIONInventors: Keizoh Kawaguchi, Ichiro Shigetomi, Kunito Takahashi

Publication number: 20210014623Abstract: A speech communication module that is to be attached in a cabin of a vehicle includes: a microphone; a loudspeaker; and a controller. The controller includes a memory storing a table that information indicating a corresponding relation between an acoustic environment parameter of an interior of the cabin of the vehicle and a vehicle type of the vehicle is stored in individually for each vehicle type. The controller is configured to acquire information indicating the vehicle type of the vehicle that the speech communication module is to be attached to from the vehicle, to read an acoustic environment parameter corresponding to the acquired vehicle type from the table, and to automatically adjust an acoustic parameter of the microphone and the loudspeaker in accordance with the read acoustic environment parameter.Type: ApplicationFiled: March 11, 2019Publication date: January 14, 2021Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATION, YAMAHA CORPORATIONInventors: Keizoh KAWAGUCHI, Ichiro SHIGETOMI, Kunito TAKAHASHI

Patent number: 9738254Abstract: A tire theft alarming system includes a vehicular device mounted to a vehicle and a mobile device carried by a user of the vehicle. When a main power supply of the vehicle is in an OFF state, the vehicular device transmits a radio wave including a first alarm based on having a variation in air pressure or acceleration of a tire, which is mounted to the vehicle, detected by a sensor transmitter for detecting and transmitting the air pressure of the tire or the acceleration applied to the tire. The mobile device carries out a warning notification to a user based on having reception of a radio wave including a first alarm transmitted by the vehicular device.Type: GrantFiled: November 26, 2013Date of Patent: August 22, 2017Assignee: DENSO CORPORATIONInventor: Ichiro Shigetomi

Patent number: 8896492Abstract: In a U-shaped deformed folded dipole antenna, a first parallel section having a feeding point includes first and second L-shape sections, and a second parallel section without a feeding point includes first and second opposing side portions and a connecting side portion coupling ends of the first and second opposing side portions. Portions of the first and second L-shape sections arranged in parallel with the first and second opposing side portions have a width W1. Portions of the first and second L-shape sections arranged in parallel with the connecting side portion have a width W2. The first and second opposing side portions have a width W3. The connecting side portion has a width W4. An impedance of the deformed folded dipole antenna is controlled by setting the width W2 to be larger than the widths W1, W3, and W4.Type: GrantFiled: November 10, 2010Date of Patent: November 25, 2014Assignee: Denso CorporationInventors: Shiro Koide, Katsuhiro Ohara, Seishin Mikami, Masaaki Hisada, Ichiro Shigetomi

Patent number: 8736501Abstract: A multi-band antenna includes two conductive wirings and unit circuits cascaded along the conductive wirings. Each unit circuit includes a communication unit, a first capacitor and a second inductor. The communication unit connects between the conductive wirings through a first inductor and a second capacitor connected in series with the first inductor. The first capacitor and the second inductor are inserted in at least one of the conductive wirings. The second inductor is connected in parallel with the first capacitor. Alternatively, the unit circuit includes a communication unit connecting between the conductive wirings through a first inductor, and a first capacitor inserted in at least one of the conductive wirings. The first inductor, the first capacitor, a third capacitor disposed between the conductive wirings, and a third inductor disposed on at least one of the conductive wirings satisfy a relationship expressed by the expression 2.Type: GrantFiled: March 20, 2012Date of Patent: May 27, 2014Assignees: DENSO CORPORATION, Nippon Soken, Inc.Inventors: Takafumi Nishi, Yuji Sugimoto, Masayuki Nakabuchi, Ichiro Shigetomi

Patent number: 8605002Abstract: In an antenna device, a first helical part of a first antenna and a second helical part of a second antenna is disposed in a dielectric body on a ground plane. Each helical part is helically wound up in a direction perpendicular to the ground plane and includes a plurality of one-turn portions. Each one-turn portion of the first helical part has a peripheral length of M times a wavelength ? of use, where M is a positive natural number. One of the one-turn portions of the second helical part closest to the ground plane has a peripheral length Ks that is N times the wavelength ? of use, where N is a positive natural number greater than M. One of the one-turn portions of the second helical part farthest away from the ground plane has a peripheral length Ke, and (M·?)<Ke<Ks(=N·?).Type: GrantFiled: February 28, 2011Date of Patent: December 10, 2013Assignees: Denso Corporation, Nippon Soken, Inc.Inventors: Takafumi Nishi, Akira Takaoka, Shiro Koide, Ichiro Shigetomi
