The present disclosure includes in one instance an optical article comprising a data rich plurality of retroreflective meats that are configured in a spatially defined arrangement, where the plurality of retroreflective elements comprise retroreflective elements having at least two different retroreflective properties, and where data rich means information that is readily machine interpretable. The present disclosure also includes a system comprising the previously mentioned optical article, an optical system, and an inference engine for interpreting and classifying the plurality of retroreflective elements wherein the optical system feeds data to the inference engine.

Metal bond abrasive articles and methods of making metal bond abrasive articles via a focused beam are disclosed. In an aspect, a metal bond abrasive article includes a metallic binder material having abrasive particles retained therein, where the abrasive particles have at least one coating disposed thereon. The coating includes a metal, a metal oxide, a metal carbide, a metal nitride, a metalloid, or combinations thereof, and the at least one coating has an average thickness of 0.5 micrometers or greater. The metal bond abrasive article includes a number of layers directly bonded to each other. Metal bond abrasive articles prepared by the method can include abrasive articles having arcuate or tortuous cooling channels, abrasive segments, abrasive wheels, and rotary dental tools. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying a metal bond abrasive article; and generating, with the manufacturing device by an additive manufacturing process, the metal bond abrasive article based on the digital object. A system is also provided, including a display that displays a 3D model of a metal bond abrasive article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of the metal bond abrasive article.

Metal bond abrasive articles and methods of making metal bond abrasive articles

A device comprising an imaging unit for capturing an image of a target object and of an accessory. The accessory comprises a reference target object having a known retroreflective coefficient. The device also comprises a calculating unit for calculating a value of a retroreflective coefficient of the target object based on a comparison of the image of the target to the image of the accessory.

Measuring device, system, method, and program

A dental light irradiation device has sensing means for sensing a change of a position of the device, and an indicator for physically indicating the position change. The invention helps controlling the positioning of the device during use.

Dental irradiation device

Problem: To provide a device, system, method, and program able to easily measure retroreflective coefficients using a commercially available mobile terminal having an imaging unit. Resolution Means: A device is provided that has an imaging unit for capturing an image of a target object, an observation angle acquiring unit for acquiring an observation angle determined by a positional relationship between the imaging unit, a light source for emitting light for capture and the target object, an entrance angle acquiring unit for acquiring an entrance angle of light emitted for capture incident on the target object, a converting unit for converting image data of an image to a luminance value of the target object using capture information of the image, and a calculating unit for calculating a value of a retroreflective coefficient of the target object based on an illuminance value and the luminance value of the target object.
