Patent number: 8120792Abstract: When a user enters control information for controlling a printing device, the information is stored in a user information storage unit. All combinations of items of the control information capable of being set by the user and values of items incapable of being set by the user, these having been selected so as to be the optimum values for the combinations, are stored as preset values in a combined information storage unit. An information storage unit compares a value in the user information storage unit with a value in the combined information storage unit. If a combination for which agreement is achieved is found in the combined information storage unit, this value is stored in a printing information storage unit and transmitted to the printing device. Thus, an optimum value can be selected and sent to the printing device even with regard to an item incapable of being selected by the user.Type: GrantFiled: March 3, 2011Date of Patent: February 21, 2012Assignee: Canon Kabushiki KaishaInventors: Takahiro Moro, Koji Yamada

Patent number: 8050837Abstract: In an inverted pendulum type mobile unit that performs inverted pendulum stabilization control and traveling control based on a velocity target value as an input variable, a change in tilt angle of a vehicle body occurring during traveling is smoothed. The target value generating portion in the inverted pendulum type mobile unit generates the velocity target value VREF of the mobile unit and the tilt angular rate target value ?REF of the vehicle body so that a second-order time derivative of VREF is continuous and ?REF is continuous with respect to time. The controller in the inverted pendulum type mobile unit calculates a torque command value Tcom for the motor drivers using VREF and ?REF as a control target to allow the mobile unit to travel at VREF while maintaining the state where the gravity center of the vehicle body or the gravity center of total mass of the vehicle body and a subject supported on the vehicle body is located above the rotation center of the wheels.Type: GrantFiled: August 28, 2007Date of Patent: November 1, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventor: Koji Yamada
