  • Patent number: 9797820
    Abstract: The present disclosure provides an electro-mechanical fuse-type configuration built into the probe that contacts the specimen during materials testing. The design includes an internal pre-loaded compression spring and an electrical contact switch. The coil spring preloaded to the desired safety load results in the probe assembly directly passing the load from the probe tip to the load cell for loads under the point where the spring additionally compresses. Upon deflection of the spring in excess of safety preload, the spring internally compresses within the probe coupling rather than the probe tip continuing to displace into the specimen, thereby switching the state of the electrical contact switch and stopping operation of the materials testing device. In a further configuration, excessive travel of the load cell coupling is detected, and, in response, operation of the materials testing device is stopped.

An electrically powered variable speed motor carries an optical encoder to sense rotary direction and speed data, which is transmitted through circuitry to an associated computer for analysis to determine control data to maintain pre-programmed motor function. Computer software determines plunger position and resultant penetration into a fruit at either pre-determined plunger speed or constant plunger resistive pressure in fine increments over the plunger trajectory and stores this data in computer memory. The precision scale is used to determine the weight of the fruit before and after the penetration tests and the difference in weight is used to automatically calculate the Specific juice Content (SJC) of the fruit.

  • Patent number: 9032784
    Abstract: A hardness tester includes a CCD camera, a monitor, a clipper (a CPU and a clipping program), and a display controller (the CPU and a display control program). The CCD camera captures an image of an indentation formed on a surface of a specimen via field lenses. The monitor displays the image of the indentation captured by the CCD camera. The clipper clips a plurality of regions from the image of the indentation captured by the CCD camera, the plurality of regions each containing a respective vertex. The display controller simultaneously displays on the monitor images of the plurality of regions clipped by the clipper.

  • Patent number: 9003871
    Abstract: A hardness tester includes an image pickup control section, an indentation region extraction section, an indentation apex extraction section and a hardness calculation section. The image pickup control section obtains picked-up image data of a sample's surface. The region extraction section binarizes the image data, determines based on the binarized image data whether an indentation region candidate is extracted, and when determining that the candidate is not extracted, obtains curvature image data, binarizes the curvature image data, erodes and dilates the binarized curvature image data, performs distance transform on the eroded-and-dilated curvature image data, and extracts a closed region corresponding to the indenter's shape using the distance-transformed curvature image data. The apex extraction section extracts an indentation-measurement-use apex based on the closed region. The hardness calculation section calculates the sample's hardness based on the apex.

  • Patent number: 8887558
    Abstract: A hardness tester and testing method including a focuser, an image capturer, a test position setter, a focus position memory, an indentation creator, an image capture controller, and a measurer. The focuser focuses on the surface of the specimen. The image capturer captures an image of the surface of the specimen. The test position setter sets a test position at which the indentation is formed. The focus position memory measures a focus position, then associates the focus position with a test position within a predetermined range and stores the information in a memory. The indentation creator forms the indentation at the test position with the indenter. The image capture controller displaces the specimen, then captures an image of the formed indentation through the first field lens. The measurer measures the hardness of the specimen based on the indentation whose image has been captured.

  • Patent number: 8839671
    Abstract: In the measurement method, a vibrator (5) of a detection unit (4) is relatively moved against a plate (3) of which surface is flat having predetermined area. The vibrator (5) which is vibrating is moved closer to a surface of an object-to-be-measured (1) which is mounted on the plate (3) until the frequency thereof is varied. A position where the frequency of the vibrator (5) is varied is output as a contact position where the vibrator (5) is contacted to the object-to-be-measured (1). Then, thickness of the object-to-be-measured (1) is measured by comparing the position where the vibrator (5) is contacted to the object-to-be-measured (1) with a surface position of the plate (3).

  • Patent number: 8657180
    Abstract: For selecting suitable bonding parameters for forming wire bonds onto bond pads of a substrate, one or more indentations are made onto at least one bond pad of the substrate with an indentation tool by applying a series of predetermined forces onto the at least one bond pad with the indentation tool. A depth-force profile of the substrate is measured comprising a relationship between each predetermined force that is applied and a resultant depth of the indentation made by the indentation tool. An appropriate set of bonding parameters suitable for forming wire bonds on the substrate is determined based on the measured depth-force profile.
