  • Patent number: 8805553
    Abstract: A method for dynamically controlling the output of a computerized manufacturing process includes storing a product target parameter in a computer memory of a computer system associated with the manufacturing process equipment. Control limit values for a product delivery statistic are provided and a product delivery parameter is continually monitored and values are stored in the computer memory. A unit product over-delivery amount is determined from the difference between the product delivery parameter and the product target parameter. A cumulative over-delivery amount is determined by summing the difference up to the current sequence number between monitored value for the previously-produced unit products and the product target parameter. A net difference is then determined between the unit product over-delivery target parameter and the cumulative over-delivery amount.

    Abstract: Systems and methods provide for the controlled application of forces to a structure during assembly, machining, manufacturing, and/or transportation operations. According to embodiments described herein, a contour control system includes a number of force control modules that are communicatively linked to a control system. The control system receives or retrieves data indicating the shape of the structure and a shape associated with a desired structure, and determines if the structure is consistent with the design specifications and any associated tolerances. The control system controls the force control modules to apply calculated forces to the structure to control the contours of the structure and/or to maintain the structure in a desired configuration. According to embodiments, the force control modules include support cradles, air cushion pads, vacuum cups, and/or other structures for selectively applying dynamic and/or static forces to the structure.

  • Patent number: 8682481
    Abstract: A media processing device, a control method for a media processing device, and a control program for the same can accurately detect the last one or specified number of media stored in the media stacker. Media stackers store media in a stack. Media processing units write data and/or print a label on the media. A media transportation mechanism has a transportation arm that can hold the media and move vertically, and transports the media between the media stackers and the media processing units by movement of the transportation arm. A control unit controls the media processing units and the media transportation mechanism 31. The control unit has a measurement unit that measures the height of media stacked in the media stacker when media is removed from the stacker by the media transportation mechanism, and a comparison unit that compares the measured media height with a reference value to detect the difference therebetween, and determines the remaining media count in the media stacker.

  • Patent number: 7920961
    Abstract: Methods and apparatuses enable generation of a managed space layout model defining permissible pathways for travel through the managed space. Each permissible pathway can be defined as a line segment or an edge bounded by coordinate pairs. Items and locations within the managed space are associated with permissible pathways, which association defines how the items/locations can be reached via travel through the managed space. The information can be saved as a network of nodes, which defines the intersection of the permissible pathways and includes information about the pathways. With the layout model, a path can be determined through the managed space to accomplish work in the managed space. The layout data allows a path distance to be calculated for a given work task that involves travel through the managed space.

    Abstract: A grinding method wherein the correlation between the amount of inertial grinding occurring in performing spark-out by a grinding unit and the maximum load current in a motor of the grinding unit is grasped, and a correction value for the amount of inertial grinding corresponding to the maximum load current is preliminarily obtained. When the wafer thickness measured by a thickness measuring gauge has reached the sum of a desired value and the correction value (=the amount of inertial grinding) corresponding to the maximum load current, the spark-out is started. Accordingly, the wafer thickness becomes the desired value after the inertial grinding in performing the spark-out.

  • Patent number: 7751923
    Abstract: A process for the automatic control of the thickness of extruded film lowers the deviations in the thickness of the film more quickly after the start of the extrusion process. The process includes the measurement of the thickness profile of the film just extruded by means of a thickness-measuring probe. The thickness-measuring probe is moved along the surface of the film substantially perpendicular to the conveying direction of the extruded film. The thickness-measuring probe records a thickness profile of the film for each measuring cycle at least over parts of the expansion of the film perpendicular to its conveying direction. While providing statistical values in relation to older measured values, the latest measured values during a predetermined time-frame at the start of the extrusion process are more heavily weighted by a computer than those measured during the normal operation.

  • Patent number: 7047097
    Abstract: Devices being controlled electronically via physical manipulation often display a resonance. In many circumstances, the frequency range of operation is not close to the resonance frequency. In these cases, the resonance can be removed through the use of simple compensation techniques such as filters. However, when the resonance frequency is close to the frequency range of operation and when the resonance frequency can change depending on temperature, time, and physical position of the device, simple compensation techniques cannot be used. The present invention presents a non-mechanical technique for providing compensation for devices with a shifting resonance. The non-mechanical technique allows for the compensation to be performed via computation.

    Abstract: A method of designing a product for use on a body used to develop a preferred product configuration using a computer-based virtual product development and testing system. A virtual wearer sub-model is created of the body and a virtual product sub-model is created of a product for use on the body. An environment sub-model is generated so that environmental factors affecting the product or the body are also used in designing or evaluating the product. Instructions defining how the wearer sub-model, the product sub-model and the environment sub-model interact are introduced in an interaction model. The sub-models and the interaction defined by the interaction model are then combined to create a virtual use model simulating the use of the virtual product sub-model by the virtual wearer sub-model. The use model determines the forces, deformations and stresses caused by movement and interaction between the virtual wearer sub-model and the virtual product sub-model using numerical method analysis.

    Abstract: Only a shadow casting object 2 is rendered using a light source placed in a virtual space as a viewpoint. As a result, a Z value corresponding to each pixel of a two-dimensional image of the object seen from the light source is written into a Z-buffer. After the rendering is completed, a mesh model 4 is generated from a plane object 3. That is, the Z value of a pixel corresponding to each vertex of the plane object 3 is read from the Z-buffer, and a Y-coordinate of each vertex is determined based on the read Z value. A shadow rendering process is executed according to a shadow volume technique using the mesh model 4 generated as described above. As such, it is possible to generate a shadow volume by a fixed and simple process without the need for exception handling.
