Abstract: A method controls an operation of an actuator. A first control signal is determined to change a position of a moving element of the actuator according to a trajectory of the moving element. A second control signal is determined to compensate for a first component of an error of the operation due to uncertainty of a model of the actuator. A third control signal is determined to compensate for a second component of the error of the operation due to an external disturbance on the actuator. The operation of the actuator is controlled based on a combination of the first control signal, the second control signal, and the third control signal.

Abstract: A bicycle seat height adjustment method is provided for changing a height of a bicycle seat. The method includes operating an operating device to output a seat raising command which is received by a motorized seat height adjustment mechanism to adjust the seat height. The method further includes releasing the operating device after the operating of the operating device. The method further includes raising the bicycle seat using the electric motor to a higher seat position that is higher than a previous seat position existing immediately prior to the seat raising command, the raising of the bicycle seat occurring only after the releasing of the operating device such that the bicycle seat remains stationary until the operating device is released.

Abstract: This invention relates to a servo system for operating an exoskeleton adapted to encircle an object of interest and for supplying a force thereon. A servomotor is coupled to a power source and operates the position of the exoskeleton and thus the force exerted by the exoskeleton on the object of interest. A measuring unit measures a raw driving current signal Iraw supplied by the power source to drive the servomotor. A low pass filter applies a low pass frequency filtering on the measured a filtered current signal Ifiltered. A processing unit determines an actuated current signal Iactuated based on the servomotor setting parameters, where Iactuated indicates the contribution to Iraw from the servomotor when operating the position of the exoskeleton. The processing unit also determines a driving force current signal Iforce indicating the force exerted by the exoskeleton on the object of interest, where Iforce is proportional to the difference between Ifiltered and Iactuated.

Abstract: A servomotor includes a motor unit generating movement of a mechanical component, a position-detecting unit detecting the position of the mechanical component, and a control unit manually controlling the mechanical component. The manual control unit is inside a main enclosure, the manual control unit is actuated by an actuator located outside the main enclosure, and the main enclosure is connected to the motor unit and to the position-detecting unit, The position-detecting unit and the motor unit are located inside first and second enclosures that are distinct from the main enclosure and are removably connected to the main enclosure. The manual control unit can be actuated when the first and second enclosures are separated from the main enclosure.

Abstract: The present invention has a communication connection means (21) which mutually connects communicatably control units (Ca, Cb) for individually controlling operations of robots (Ra, Rb) to constitute a network, input means (37a, 37b) which are respectively installed in the control units and input operation instructions of the robots, and timing signal generation means (69a, 69b). The control units are selectively set to any one of an independent function execution mode, a master function execution mode, and a slave function execution mode, and among the control units, the control unit (Ca) to perform a master operation is set to the master function execution mode, and the residual control unit (Cb) is set to the slave function execution mode, and by correcting a minimum interruption period (Ts(b)) of the slave side control unit (Cb), a control time (ta11, ta12, ta13) to the master robot (Ra) of the master side control unit (Ca) is delayed by a predetermined time (T) to perform the cooperative operation.

Abstract: A manual operation device for controlling an instrument mounted on an automotive vehicle includes: an operating portion to be operated manually; an actuator for applying a force to the operating portion; a detection portion for detecting an operation position of the operating portion; a memorizing element for memorizing a force pattern; a receiving element for receiving the force pattern from an external device and for memorizing the force pattern in the memorizing portion; and a control element for reading out the force pattern memorized in the memorizing portion, for outputting the control data to the actuator on the basis of the read out force pattern and the operation position of the operating portion detected by the detection portion, and for outputting the operation signal to the instrument.

Abstract: The mechanism has a drive roller which engages the cord that opens and closes a closure member such as a drapery. An electric motor that rotates the driver roller is supplied with power through first and second timed switches. An adjustment associated with the first timed switch may be set to control the times at which power to the electric motor is initiated, while an adjustment associated with the second timed switch may be set to determine the interval after which power to the electric motor is terminated.
