An apparatus and method for establishing triggers for the opening of one or multiple gates to a mold cavity of an injection molding system, followed by a sequence of predetermined valve pin movements over the course on an injection cycle. In one embodiment, the invention provides a graphical user interface and control system enabling a user to select from and arrange a plurality of virtual icons into a user-defined virtual sequence that define associated triggering events and actuator controlled pin movements over the course of an injection cycle. In various embodiments, the apparatus and method allows the system operator to view a simulated profile of such triggers and movements and to compare the simulated profile to an actual profile to access differences and make adjustments to the triggers and sequencing more quickly and efficiently. This is particularly useful in sequential molding systems where multiple gates need to be programmed and adjusted to compensate for variations from a predetermined sequence.

A manipulation system includes: a manipulator that operates a microscopic object; a first input unit that generates a first movement command signal for moving the manipulator to a manipulator position corresponding to an input operation position; and a second input unit that generates a second movement command signal for moving the manipulator to a manipulator stored position stored in a storage. When the input operation position of the first input unit is a predetermined input operation position, the manipulator is enabled to be moved by an operation of the first input unit, or the manipulator is enabled to be moved by an operation of the second input unit.

A motor control device capable of promptly positioning a driven object at a target position, while suppressing backlash. The motor control device includes an operation command generation section for generating a first operation command and a second operation command for first and second motors to move the driven object; a preload command generation section for generating a first preload command which is added to the first operation command and a second preload command which is added to the second operation command in order that drive axes of the first motor and the second motor provide the driven object forces in opposite directions; and a preload command adjustment section for adjusting the first preload command and the second preload command in order that an absolute value of the above forces is decreased when an operation amount exceeds a predetermined threshold value.

A power tool includes a motor having an output shaft, an extensible member driven by the motor, a working assembly movable in response to contact with a distal end of the extensible member, a first sensor configured to detect a home position of the extensible member, a second sensor configured to detect rotation of the motor output shaft, and a controller in electrical communication with the first and second sensors. The controller is configured to drive the motor output shaft in a first rotational direction a predetermined number of revolutions counted by the second sensor, thereby displacing the extensible member from the home position. The controller is also configured to drive the motor output shaft in an opposite, second rotational direction to thereby return the extensible member until the home position is detected by the first sensor.

Method for positioning and orienting a first object relative to a second object. The method includes positioning a near field transducer having an aperture on the first object, and directing a laser light toward the aperture of the near field transducer on the first object to create an evanescent wave on the other side of the aperture. Positioning a sensor on the second object for detecting the effervescent wave from the near field transducer. Providing an algorithm, and using information obtained from the sensor on the second object in the algorithm to control a nanopositioning system to position one of the first object and the second object in a desired position and orientation relative to the other one of the first object and the second object.

A servo motor controller includes: a servo motor; a driven member which is driven by the servo motor and in which a load acting on a drive axis is varied depending on the position of the driven member; a position detection portion and a speed detection portion for the driven member; and a motor control portion, where the motor control portion includes: a position control portion which calculates a speed command based on a positional error between a position command for the driven member and the position FB; a speed control portion which calculates a torque command by multiplying a speed error between the speed command and the speed FB by a speed gain and/or adding a torque offset to the speed error; and a change portion which changes at least one of the speed gain and the torque offset according to the position of the driven member.

A motor controller which controls a servo motor for driving a machine, includes: a speed command unit which commands the speed of the machine; a speed detection unit which detects the speed of the servo motor; and a speed control unit which produces a torque command based on a speed command and a motor speed detected so as to control the speed of the servo motor, where the speed control unit includes a filter which approximates the inverse characteristic of a transmission characteristic from the servo motor to the machine, the filter has a transmission characteristic F(s) based on a frequency , a vibration damping coefficient and a cutoff frequency .sub.adj which are adjustment parameters and the frequency is adjusted so as to be equal to or more than an antiresonant frequency .sub.0 of the machine but less than a resonant frequency .sub.p.

A system and method for designing scleral lenses includes a computer, a camera and a lathe connected by a network. The camera captures a set of sagittal images at each of a set of sagittal places of an eye. A combined sagittal image is created from each set of sagittal images. A spline curve is defined for each combined sagittal image creating a set of spline curves. A set of back surface curves if created from the set of spline curves. A back lens surface is generated from the set of surface curves. A front lens surface is generated adjacent the back lens surface. A point cloud is generated from the back lens surface and the front lens surface. The point cloud is converted to a lens image. The lens is converted to a test file for use by the lathe to cut the scleral lens.
