Patent number: 11513680Abstract: An information processing apparatus includes a display unit, a touch sensor disposed on the display unit and detects contact with an object on the display unit, a main system, and an embedded system. The embedded system generates image data of an input area for a virtual input device, output image data of the input area to the main system by using a first general-purpose interface protected by the main system, and output input information, which is based on detection information detected in the input area by the touch sensor, via the virtual input device to the main system by using a second general-purpose interface protected by the main system. The main system displays, on the display unit, the image data of the input area output by the embedded system.Type: GrantFiled: September 30, 2021Date of Patent: November 29, 2022Assignee: Lenovo (Singapore) Pte. Ltd.Inventors: Yoshimitsu Imanishi, Seiichi Kawano, Kazunori Yamamura, Yoshitsugu Suzuki, Mitsuhiro Yamazaki, Ryohta Nomura

Patent number: 10444841Abstract: A haptic actuator for generating haptic feedbacks to provide perceptions of different characteristics is provided. The haptic actuator includes a vibration mechanism and a striking mechanism. The vibration mechanism, in response to a receipt of a predetermined electric power, applies a steady vibration to a vibrating body. The striking mechanism, in response to the receipt of an electric power larger than the predetermined electric power, strikes the vibrating body in order to provide a haptic feedback to the vibrating body. The haptic actuator is able to apply a vibration according to the vibration mechanism and a vibration according to the striking mechanism to the vibrating body.Type: GrantFiled: August 30, 2017Date of Patent: October 15, 2019Assignee: LENOVO (SINGAPORE) PTE LTDInventors: Fusanobu Nakamura, Mitsuhiro Yamazaki, Atsushi Nagashima, Kazunori Yamamura
