Patent number: 7813892Abstract: A motion detection apparatus includes an acceleration sensor which detects acceleration generated by motion of an electronic device; a motion detecting section including a statistical processing section which calculates the average value of data provided from the acceleration sensor, calculates the difference between the average value and the last value of the data obtained, and calculates a pseudo-variance value of the data from the calculated difference; a threshold comparing section which compares the pseudo-variance value calculated by the motion detecting section with a motion threshold to generate a signal value in response to determination that the pseudo-variance value has exceeded the motion threshold; a first buffer memory which sequentially stores signal values generated by the threshold comparing section at predetermined time intervals; and a signal generating section which includes means for adding up values in the first buffer memory, thereby appropriately associating with motion.Type: GrantFiled: November 1, 2005Date of Patent: October 12, 2010Assignee: International Business Machines CorporationInventors: Takashi Sugawara, Kohji Kawahara, Yuji Chotoku

Patent number: 7502952Abstract: A method and system are provided for thermal management of a CPU. Both hardware and software data are used to periodically calculate a power consumption index. An internal database is provided to convert power consumption data to rotational speed of an associated cooling fan for the CPU. Based upon a change in the calculated power consumption, the rotational speed of the fan may be adjusted to accommodate the change in power consumption. Accordingly, the method and system monitors and adjusts the rotational speed of the cooling fan based upon available hardware and software data.Type: GrantFiled: July 11, 2007Date of Patent: March 10, 2009Assignee: International Business Machines CorporationInventors: Yuji Chotoku, Rieko Kataoka, Takayuki Katoh

Patent number: 7409565Abstract: A power control method for a magnetic disk unit is disclosed. The method includes identifying a type of a last instruction sent to a magnetic disk unit and, in response to identifying the type, setting a wait time that varies according to the type. In response to the wait time having elapsed after a completion of processing ordered by the last instruction, an idle instruction is sent to the magnetic disk unit for placing the magnetic disk unit in an idle state in which power consumption is reduced.Type: GrantFiled: December 15, 2005Date of Patent: August 5, 2008Assignee: Lenovo (Singapore) Pte. Ltd.Inventors: Yuji Chotoku, Takashi Sugawara, Takashi Yomo

Publication number: 20060178108Abstract: An information processing device capable of controlling radio wave transmission is disclosed. The information processing device includes an acceleration detection unit and a flag setting unit. The acceleration detection unit detects an acceleration applied to the information processing device. In response to the magnitude of the detected acceleration and the magnitude of the tilt of an airplane determined from the detected acceleration being larger than a predetermined value, the flag setting unit sets a stopping flag. Then, the flag setting unit stops any radio wave transmission from the information processing device.Type: ApplicationFiled: February 9, 2006Publication date: August 10, 2006Inventors: Yuji Chotoku, Kan Sasaki
