Patent number: 9939926Abstract: A pointing device is disclosed. The pointing device includes an operation cap having an operation surface fitted into a stud. The stud is fixed to a keyboard plate with a screw from below together with a sensor plate. A waterproof material is provided between the stud and the keyboard plate. Multiple pressure sensors are arranged below the keyboard plate. The pressure sensors are applied with a predetermined pressure beforehand. When the operation surface is depressed, the stud and the sensor plate slide and move downward while being tilted to reduce the detection pressures of the pressure sensors. Since the pressure sensors exist below the keyboard plate, the operation cap can be downsized, and the pressure sensors can be protected from impact to the operation cap.Type: GrantFiled: February 4, 2016Date of Patent: April 10, 2018Assignee: LENOVO (SINGAPORE) PTE LTDInventors: Fusanobu Nakamura, Mitsuhiro Yamazaki, Akihiko Mizutani

Patent number: 9847192Abstract: A keyboard device is disclosed. The keyboard device includes a base, a key top, a film actuator, a position sensor, and a controller. The key top is movably arranged on the upper surface side of the base. Disposed between the base and the key top, the film actuator bends according to an applied voltage. Also disposed between the base and the key top, the position sensor detects a position of the key top. The controller applies a voltage to the film actuator in order to generate a repulsive force corresponding to the position of the key top detected by the position sensor.Type: GrantFiled: March 17, 2015Date of Patent: December 19, 2017Assignee: LENOVO (SINGAPORE) PTD LTEInventors: Akihiko Mizutani, Fusanobu Nakamura, Mitsuhiro Yamazaki

Patent number: 9430056Abstract: A pointing device for a portable computer is disclosed. The pointing device includes an operation cover for covering a first and second pressure sensors. The pointing device also includes one front operation surface and two rear pressure faces. Detection axes are arranged in a vertical direction, and the pressure faces are so inclined that normal lines will approach each other above the operation surface. The operation surface is applied with depression pressure P1 including a horizontal component Ph and a vertical component Pv. Even when any position on the operation surface is pressed down, pressure P2a detected by the first pressure sensor becomes greater than pressure P3a detected by the second pressure sensor.Type: GrantFiled: July 22, 2014Date of Patent: August 30, 2016Assignee: LENOVO (SINGAPORE) PTE LTDInventors: Akihiko Mizutani, Fusanobu Nakamura, Mitsuhiro Yamazaki

Patent number: 8499143Abstract: A computer system having an operating environment configured for enabling boot up in a relatively short time is disclosed. A hard disk is utilized to store a boot file. A run process list registers a process to be run during boot up. When the computer system is being booted up, if the run process list registers a process to load the boot file, a process control unit does not control a process management unit, so that the process is run as usual. If the process is not registered, the process management unit suspends the process. When the suspended process is called by another process later, the process control unit makes the process resumed on demand.Type: GrantFiled: October 25, 2010Date of Patent: July 30, 2013Assignee: Lenovo (Singapore) Pte LtdInventors: Hiroshi Itoh, Akihiko Mizutani, Susumu Shimotono, Kunihiko Miwa
