Publication number: 20230304687Abstract: A wireless network system is incorporated in an air conditioning system. A user is accessible to the wireless network system for controlling the air conditioner. The wireless network system includes an AP (access point) equipment, an air conditioning controller and a user-operable terminal. The terminal and the air conditioning controller are connected communicably and wirelessly when a dedicated application is actuated in the terminal. AP information (such as a password) is transmitted from the terminal to the air conditioning controller to establish coordination (i.e., pairing) between the terminal and the air conditioning controller in a state where the terminal and the air conditioning controller are connected mutually and wirelessly. The AP information identifies the AP equipment. In this coordinated state, the access to the AP equipment is executed based on the AP information. Authentication is performed when the terminal and the air conditioning controller are mutually and directly connected.Type: ApplicationFiled: March 28, 2022Publication date: September 28, 2023Applicant: DENSO WAVE INCORPORATEDInventor: Kensuke NAKAJIMA

Patent number: 11733622Abstract: An imaging system includes a belt roller extending in an axial direction, an endless belt to rotate about the belt roller, a steering roller located inside the endless belt and extending in the axial direction, a steering roller actuator located at an end portion of the belt roller in the axial direction to contact the endless belt, and a support. The steering roller actuator is displaceable in the axial direction in response to a shifting of the endless belt so as to tilt the steering roller with respect to the axial direction. The support supports the endless belt in a gap formed between the belt roller and the steering roller actuator when the steering roller actuator is displaced in the axial direction.Type: GrantFiled: October 20, 2020Date of Patent: August 22, 2023Assignee: Hewlett-Packard Development Company L.P.Inventors: Kensuke Nakajima, Satoru Hori, Yuji Aoshima

Patent number: 11422487Abstract: An imaging system includes an endless belt, a tension roller to engage the endless belt, a steering roller to contact the endless belt and a tilting mechanism to tilt the steering roller. The tension roller has a first end adjacent a first edge portion of the endless belt and a second end adjacent a second edge of the endless belt. A first belt meandering detection member is located at the first end of the tension roller. A second belt meandering detection member is located at the second end of the tension roller. The tilting mechanism operates the steering roller between a first mode wherein the first edge portion of the endless belt contacts the first belt meandering detection member, and a second mode wherein the second edge portion of the endless belt contacts the second belt meandering detection member.Type: GrantFiled: January 14, 2020Date of Patent: August 23, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventor: Kensuke Nakajima

Patent number: 11169470Abstract: An imaging system includes a pair of belt rollers, a steering roller, a wheel, and a link mechanism. The pair of belt rollers includes a first roller and a second roller to drive an endless belt along a belt path. The steering roller is between the first roller and the second roller. The steering roller is tiltable to engage the endless belt. The wheel is at an end of the first roller in abutment with an edge of the endless belt, to move in an outward direction along a rotation axis of the first roller, when the endless belt shifts away from the belt path toward the wheel. The link mechanism is between the wheel and the steering roller to tilt the steering roller in response to a sliding movement of the wheel in the outward direction, to urge the endless belt to shift toward the belt path.Type: GrantFiled: October 12, 2018Date of Patent: November 9, 2021Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Koji Miyake, Satoru Hori, Kensuke Nakajima, Yuji Aoshima
