  • Publication number: 20080275576
    Abstract: A system for motion control in which an application is developed that is independent from the actual motion control hardware used to implement the system. The system comprises a software system that employs an application programming interface comprising component functions and a service provider interface comprising driver functions. A system programmer writes an application that calls the component functions. Code associated with the component functions relates these functions to the driver functions. A hardware designer writes driver code that implements the driver functions on a given motion control hardware product. The driver functions are separated into core and extended driver functions. All software drivers implement the core driver functions, while the software drivers need not contain code for implementing the extended driver functions.

  • Patent number: 7310560
    Abstract: A drive device for a load (18a) comprises a device for detecting accidental collisions with a motor (14a), a first, respectively a second position sensor (15a, 16a) disposed upstream, respectively downstream of a transmission assembly (12a) providing first and second values of position. A calculation unit (20) makes it possible to calculate an error signal (d) corresponding to the difference of these position values. Ways to discriminate are devised so as to analyze the successive error signals as a function of the path (xR) traversed by the load in a spatial reference frame (xR, d). Filters with rectangular spatial window or with exponential spatial window are particularly adapted for discriminating between errors due to an accidental collision and those due to other causes attributable to normal operation. One thus obtains particularly reliable and sensitive collision detection with a very low detection threshold.

  • Patent number: 7203552
    Abstract: A method, or corresponding apparatus, for controlling deformation of a structure, in part, includes applying a command signal at a first signal level to at least one actuator mechanically coupled to a structure, the first signal level known to produce an energy level in the actuator(s) substantially the same as an energy level currently stored by the actuator(s). The method enables the actuator(s) to respond to the command signal by applying an electrical reference to the actuator(s). The method drives the command signal from the first signal level to a second signal level, changing the actuator(s) in at least one dimension as a function of the command signal, which results in a corresponding deformation of the structure. The method electrically disables the actuator(s) by removing the electrical reference, which results in maintaining deformation of the structure defined by energy stored by the actuator(s).

  • Patent number: 7013183
    Abstract: A multiplexer (MUX) driver system controls a deformable mirror, in part, by enabling and disabling individual or multiple actuators, mechanically coupled to the deformable mirror, through use of switches (e.g., solid-state switches) electrically coupled between the actuators and a reference node. In operation, the driver system enables actuator(s) by closing respective switch(es) and driving the enabled actuator(s) to deform respective portions of the deformable mirror in a controlled manner. The driver system disables the actuator(s) by opening the respective switch(es) to decouple the actuator(s) from the reference node. The switches, in the open state, prevent respective actuators from discharging, thereby allowing a desired surface figure of the deformable mirror to be maintained for long periods of time without having to refresh the actuators.

  • Patent number: 7006084
    Abstract: The invention relates to a computer-based method and system to facilitate quality control for manufactured assemblies based on computer aided design (CAD) files. The instant invention mitigates the problems encountered with large CAD files by decomposing each of such files into a multi-file format. A large CAD file is thereby broken-down into smaller files that organize the information contained in the larger file. The organization is performed in such a way that the information pertinent to the measurement process is segregated into a different smaller file than the information not needed to calculate measurements. Thus, the computer running the computation accesses a smaller file containing a higher percentage of required information. Additionally, assisting the user in coordinating a match-up between the physical surfaces being measured and the proper associated CAD model version of that surface further increases the handling speed.

    Abstract: The present invention discloses a method, system and apparatus for use in a roll grinding machine. Data is read from an RFID tag automatically by providing an RF read/write sensor on a movable cylinder rod. The RF sensor is held away from the work roll area while the work roll is loaded or removed. When the work roll is placed in the position for grinding, a signal to rotate the roll is sent to the grinding machine, and also operates to advance the cylinder rod. An RFID tag embedded in the work roll and containing identification and other data related to the work roll, is read by a read/write sensor, and the data is then transferred from the sensor to a serial control interface, which converts the data and transmits the information to the grinding machine control desk and the computer control management data base.

  • Patent number: 6973355
    Abstract: A positioning system including a sensor, a drive sequencer and an actuator. The sensor senses the actuator position and provides position signals to drive the sequencer which responsively computes and drives the actuator in open loop moves containing dwell intervals of position. The actuator positions a mirror or other load means to reflect an optical beam as desired. Either preprogrammed or non-repeating sequences of actuator stopping positions can be synchronized with a laser. During dwell times, mirror position accuracy better than 10 microradians is suitable for tuning CO2 pulse burst or CW lasers.

  • Patent number: 6968258
    Abstract: A system and method 100 of using residual feedback in a control loop in a manner that substantially eliminates the steady state error in the predicted states that results from the mismatch in gain between the plant and the model. The control effort used by the estimator to predict the next position is modified to compensate for this difference in gain. By integrating the residual, and modifying the apparent control effort accordingly, the residual is driven to have a mean value of zero. When the residual goes to zero, by definition, the steady state error in the position state goes to zero; and to the extent that the model matches the plant, the velocity state also approaches zero such that the steady state error in the predicted states are substantially eliminated, allowing for improved control.

  • Patent number: 6961629
    Abstract: This invention provides an output service provision system which is capable of allowing a user to easily receive a provided output service, providing an output service responsive to the user and flexibly coping with situational variations. Upon determining that a virtual object B is in an area-in state with respect to a virtual object A, a virtual object management device can transmits an area-in notification to a projector. Upon receiving the area-in notification, the projector can transmits a projector display data transmission request to a portable terminal and receives projector display data transmitted in response to the transmission request. The projector can then executes a projection process by a projection device on the basis of the received projector display data. The portable terminal can transmits the projector display data to the projector in response to the projector display data transmission request.

  • Patent number: 6934591
    Abstract: A control system (102) operates within a dynamic range, and a follow-up system (104) is commanded to reduce a positional error between the follow-up system and the control system when the dynamic range is exceeded. A linear follow-up command may be initially provided once a dead band value (208) is exceeded. The follow-up system (104) is driven relative to its base mount (103) in a direction to reduce the positional error to within a null value range (214). The follow-up command may also implement a decay function to control the follow-up system (104). A control variable transfer function may also be utilized to gradually subtract the dead band value from the follow-up system position error command as a function of time. The decaying function may include linear as well as non-linear decaying functions. In one embodiment, a figure eight-type hysteresis control function may be implemented to control the inertial position of an inertial element.

  • Patent number: 6920363
    Abstract: An acceleration and deceleration control in which, for a relation between speed and acceleration, the low speed part need not be symmetrical with the high speed part, is performed such that an actual acceleration curve may lie along a restricted acceleration curve as much as possible. A curve representing actual acceleration-speed, corresponding to time-speed transition to be planned, approaches a restricted acceleration curve. When supplying a movement command which has been subjected to acceleration and deceleration processing to a servo control section, acceleration in the acceleration and deceleration processing is determined such that a speed-acceleration curve of the movement command which has been subjected to acceleration and deceleration processing may lie along predetermined speed-acceleration curve. The speed-acceleration curve is set for each axis and dependent on acceleration or deceleration, using parameters.

  • Patent number: 6912444
    Abstract: A position transducer is connected to merely one input circuit. The outputs of the input circuit are connected, transmitted or routed, in part, to a first and to a second counter circuit. For the counting process, the first counter circuit uses the digital signals of the input circuit, while the second counter circuit generates digital signals from the analog signals and uses them for the counting process. It is, thus, possible, in spite of a not fully two-channel processing of the signals of a position transducer, to set up a reliable position monitoring using only one position transducer.

  • Patent number: 6889099
    Abstract: A distributed control system having system components (1, 2, 3). The positions of the system components (1, 2, 3) are stored in respective memories (11, 12, 13) as component-specific data, which represent the spatial coordinates of the positions. The system components (1, 2, 3) transmit their respective positions to a configuration unit (4) via a communications channel (5). By means of a layout plan, e.g., in the form of a piping and installation diagram, the component-specific data of the individual system components (1, 2, 3) is assigned to the configured system components. In addition, a respective physical address is assigned to each of the system components (1, 2, 3). This achieves simple and reliable configuration of the system components (1, 2, 3). The distributed control system is used, in particular, in process apparatuses.

  • Patent number: 6885908
    Abstract: A determining method of movement sequence and a positioning apparatus of the invention are arranged in such a manner that, in order to measure positions of plural marks as being measurement targets provided on a wafer within a shorter time, a group including executable movement sequences is generated out of a group of movement sequence candidates, each indicating a measurement order of these marks, and a movement sequence that accomplishes a movement operation between the marks within the shortest time is obtained from the group thus generated. For efficiently searching an optical system as a globally optimal solution within a shorter computation time, independently of an initial solution given, a designing method of optical system of the invention obtains the optimal solution of the optical system to be designed, using an evolutionary computation method (genetic algorithm) having a genetic operator for handling continues values explicitly.
