20090108605 | Robot Gripper and Method for Its Manufacture - The invention relates to a robot gripper having a fixing flange for detachably attaching it to a robot manipulator arm, and at least one actuator element which is supported in a frame, that actuates at least two gripper jaws indirectly or directly kinematically via at least one articulated unit. At least the fixing flange, the frame and the actuator element are manufactured integrally using a generative manufacturing method, and the actuator element is in the form of a bellows, enclosed an internal volume, which can be filled with a medium via at least one opening, and is capable of expanding, when filled with a medium, along a linear axis predetermined by the bellows design of the actuator element and of contracting, when the volume is emptied, in the opposite direction. | 04-30-2009 |
20120118705 | DEVICE AND METHOD FOR FEEDING A MATERIAL LAYER ONTO A CONSTRUCTION PLATFORM, OR ONTO AT LEAST ONE MATERIAL LAYER LOCATED ON THE CONSTRUCTION PLATFORM, FOR PRODUCING AN OBJECT IN THE COURSE OF A GENERATIVE PRODUCTION METHOD - A device and a method are described for feeding a material layer onto a construction platform, or onto at least one material layer located on the construction platform, for producing an object, which is mounted so it is linearly movable relative to a material reservoir and the construction platform along a motion plane, to which the material reservoir and the construction platform can be orthogonally deflected. A circulating band IS stretched around at least two molded bodies, which contacts at least in segments the molded bodies. a drive circulates the band around the at least two bodies. The band has a band segment which can be fixedly assigned relative to at least one body in the longitudinal section around the at least two molded bodies. The band segment at least in segments contacts the material stored in the material reservoir during the linear motion from the material reservoir to the construction platform so that at least a part of the material can be stripped off from the material reservoir and can be applied as the material layer to the construction platform to compress the material layer. | 05-17-2012 |

20140300542 | PORTABLE DEVICE AND METHOD FOR PROVIDING NON-CONTACT INTERFACE - A method for controlling operations of a portable device through a touch-free user input in the portable device having a projector module is provided. To this end, once the projector module is driven, an application execution screen is projected through the projector module, and if a proximity event is detected, a camera module is activated to acquire an image from which a user gesture is recognized. The pointer on the projected image is controlled corresponding to the user gesture. The user gesture is used to dispatch an application as well as to control the pointer. In this way, a user may view an image projected from the projector module of the portable device without jittering while intuitively manipulate the portable device without touching the touch screen, such that user convenience is maximized. | 10-09-2014 |
20150042621 | METHOD AND APPARATUS FOR CONTROLLING 3D OBJECT - A method for controlling a 3D objects includes photographing an image of an external object that operates 3D objects displayed in a user device, extracting, from the obtained image, one or more feature points included in the external object, determining, from the extracted feature points, one or more effective feature points used in operation the 3D objects; and tracing the determined effective feature points to sense an input event associated with the operation of the 3D object. An apparatus includes a camera configured to obtain an image of an external object for operating 3D objects, and a controller configured to extract feature points of the external object from the obtained image, determine one or more effective feature points used in operation the 3D objects from the extracted feature points, and trace the determined effective feature points to sense an input event associated with the operation of the 3D objects. | 02-12-2015 |

20090248345 | Probe Calibration - A method of calibrating a probe is disclosed said probe being mounted on a machine and having a stylus with a workpiece contacting tip, comprising calculating calibration information for the probe for a first orientation of the probe, and rotating the calibration information by an angle to obtain a probe calibration information for when the probe is oriented by that angle with respect to the first orientation. Also disclosed is a method of calibrating a probe during a measurement process. The calibration information may include a vector which relates probe head axes to machine axes; a calibration matrix; datum data; an inertial matrix. The stylus tip may be datumed at the orientation of the probe or inferred from datum information obtained at different orientations. The rotation step may be carried out by a software/computer program which may be stored on a controller for the machine. | 10-01-2009 |
20100101104 | APPARATUS AND METHOD FOR CALIBRATING A SCANNING HEAD - A method of calibrating a measurement scale in a motorised scanning head using a reference artefact is described. The method comprises the step of rotating a surface sensing device, such as a scanning probe, mounted on the scanning head about at least one axis of the scanning head to move the surface sensing device into a plurality of different angular orientations relative to the reference artefact. A step is then performed of measuring, with the surface sensing device, at least one property of the reference artefact at each of the different angular orientations. An error map or function is then created for at least one measurement scale of the scanning head using the properties of the reference artefact measured and optionally known or calibrated properties of that reference artefact. The method may comprise use of co-ordinate positioning apparatus, such as a co-ordinate measuring machine, to move the scanning head. The reference artefact may comprise a single feature or an array of features. | 04-29-2010 |
20100119104 | APPARATUS AND METHOD FOR SURFACE MEASUREMENT - A method of determining the dimensions and location of a surface feature, for example a valve seat. The surface of the feature is measured, for example using a spiral scan path with a tactile probe and the multiple data points acquired from the scan are used to create a digitized image. The digitized image is fitted to a nominal image (e.g. CAD data) of the surface feature. The deviation of the digitized image from the nominal image is used to determine at least one of the dimensions, location and form deviation of the surface feature. | 05-13-2010 |
20100132432 | SURFACE SENSOR OFFSET - A method of operating a coordinate positioning apparatus having a surface sensor that is rotatable about at least a first axis. The method comprises obtaining a first measurement with the surface sensor at a first angular orientation and obtaining a at least a second measurement with the surface sensor at a second angular orientation. The first and second angular orientations are different to each other such that any offset of the surface sensor from an expected position will have at least a partially opposing affect on the first and second measurements. The method then compensates and/or establishes for the offset using the first and second measurements. | 06-03-2010 |
20110184695 | MEASUREMENT METHOD - This invention relates to a method for measuring a feature of an object that comprises obtaining a representation of at least the feature on the object by acquiring multiple data points via surface measurement of at least the feature. A model substantially replicating at least the feature of the object is fitted to the representation. The model comprises parameters defining at least two independently alterable portions that are linked at a common point. The fitting comprises changing the form of the model by altering at least one of the at least two independently alterable portions. The method also comprises obtaining information regarding at least the feature from the fitted model. | 07-28-2011 |
