Abstract:
A mechanism is described for facilitating smart measurement of body dimensions despite loose clothing and/or other obscurities according to one embodiment. A method of embodiments, as described herein, includes capturing, by one or more capturing/sensing components of a computing device, a scan of a body of a user, and computing one or more primary measurements relating to one or more primary areas of the body, where the one or more primary measurements are computed based on depth data of the one or more primary areas of the body, where the depth data is obtained from the scan. The method may further include receiving at least one of secondary measurements and a three-dimensional (3D) avatar of the body based on the primary measurements, and preparing a report including body dimensions of the body based on at least one of the secondary measurements and the 3D avatar, and presenting the report at a display device.

A laser tube-cutting machine is disclosed. The tube-cutting machine may include a processing station where raw material enter the machine, a holding and positioning station configured to hold and position the raw material, at least one combined measurement and laser cutting station including a laser and at least one sensor configured to measure various aspects of the tube both before and after cutting, and an outflow processing station where cut material exit the machine.
Abstract:
A homography between two captured images of a planar object is decomposed into at least one possible solution, and typically at least two ambiguous solutions. The ambiguity between the two solutions is removed, or a single solution validated, using measurements from orientation sensors. The measurements from orientation sensors may be used by comparing at least one of the yaw, pitch, and/or roll angles derived from a relative rotation matrix for the one or more solutions to a corresponding at least one of the yaw, pitch, and/or roll angles derived from the measurements from the orientation sensors.
Abstract:
A method and a system for height triangulation measurement are disclosed. The method and the system are particularly useful for measuring the height of an object on a surface e.g., bumps or small wafer. Three steps do the measurement. The first step is illuminating the object from a known angle with a narrow strip of light being spatially incoherent, having a large numerical aperture along the light strip and a small numerical aperture perpendicular to the light strip. The second step is imaging the object from a known angle having said large numerical aperture along the light strip and the small numerical aperture perpendicular to the light strip, having an image that includes the object and the light strip and the last step is calculating the height of the object from the location of the light strip on the image.
Abstract:
The invention relates to a device for measuring work pieces using an image processing system. The inventive device comprises a camera, an evaluation unit and a support for positioning the work pieces in front of the camera. The invention enables the precise detection of work piece coordinates with regard to the contour of the work piece also when the contour of the work piece is not sharply displayed in the required viewing direction of the camera. To this end, the invention provides that the support (1) comprises at least one marking (6a, b, c) as a point of reference for the work pieces (3), and comprises a defined supporting surface (10) for the work piece (3) whose coordinates with regard to the marking (6a, b, c) are at least partially stored in advance.
Abstract:
The present invention concerns a method for inspecting the surface of an object (10) such as a wafer comprising tridimensional structures (11), using a confocal chromatic device with a plurality of optical measurement channels (24) and a chromatic lens (13) allowing optical wavelengths of a broadband light source (19) to be focused at different axial distances defining a chromatic measurement range, the method comprising a step of obtaining an intensity information corresponding to the intensity of the light actually focused on an interface of the object (10) within the chromatic measurement range at a plurality of measurement points (15) on the object (10) by measuring a total intensity over the full spectrum of the light collected by at least some of the optical measurement channels (24) in a confocal configuration.
Abstract:
The present invention concerns a confocal chromatic device, comprising : at least one chromatic lens (13) with an extended axial chromatism; at least one broadband light source (19); at least one optical detection means (20, 21); and at least one measurement channel (24) with a planar Y-junction (18) made with a planar waveguide optics technology, and arranged for transferring light from said at least one light source (19) towards said at least one chromatic lens (13) and for transferring light reflected back through said at least one chromatic lens (13) towards said at least one optical detection means (20, 21).
Abstract:
A method is provided for detecting one or more analytes in a sample. The method relies, in part, on the ability of functionalized particles added to the sample to partially or completely inhibit the transmission of electromagnetic radiation into and out of the sample through a detection surface in a reaction vessel containing the sample. In a microarray format, the invention can be used to screen millions, billions or more biological elements, such as an organism, cell, protein, nucleic acid, lipid, saccharide, metabolite, or small molecules. Methods, apparatuses and kits are described.
Abstract:
Embodiments described herein generally relate to methods and apparatuses for ensuring the integrity of probe card assemblies and verifying that probe cards are ready for testing. In one embodiment, an apparatus includes a stage that allows stable and precise movement of a sensor. The stage includes a first support, a second support, and a sensor carrier. A plurality of lifting devices is coupled to the second support and the sensor carrier, providing a more stable and precise movement for the sensor carrier.
