An automatic faucet system includes a sensor and a controller. The sensor includes an emitter constructed and arranged to emit light having a first polarization toward an object. The sensor further includes a detector configured to detect light reflected from the object having a second polarization that is different from the first polarization. The controller is operatively coupled to the detector. The controller is configured to supply water to a faucet, or other water supply, upon sensing by the detector the light having the second polarization. By sensing in such a manner, the level of false positive readings in the system is reduced. The detector is further configured to determine the location of the object so that the faucet is only activated when the object is in close proximity to the faucet.

A surface capacity parameter is determined for a surface of an article having irregularities therein that can be characterized by peaks and valleys relative to a reference point. Initially, an area of interest on the surface of the article and a lateral resolution of that area of interest are determined. An apparatus generates a visual representation of the area of interest on the surface of the article. A deflection contact part factor for the article is calculated, and a bearing ratio curve level is determined based upon the calculated deflection contact part factor and the magnitude of the height or distance between the tallest peak and the lowest valley on the surface of the article. The volume of the material comprising the peaks in the surface of the article and the volume of the space in the surface of the article that is available for the retention of a fluid, such as a lubricant, are determined. Lastly, a surface capacity parameter is calculated as the ratio of the volume of the material comprising the peaks in the surface of the article to the volume of the volume of the space comprising the valleys in the surface of the article.

Method and apparatus for measuring, analyzing, and characterizing irregularities on a surface of an article

A method for measuring irregularities on the outer surface of an article employs an apparatus to obtain qualitative information regarding a first portion of the outer surface of the article, which can be used to generate a visual representation of a first portion of the outer surface of the article. Then, the article is moved by a predetermined amount, and the apparatus is again used to generate a visual representation of a second portion of the surface of the article. This process is repeated to obtain a plurality of visual representations that together span across a predetermined amount of the surface of the article. Then, the plurality of visual representations are processed to generate a single comprehensive enlarged visual representation of a relatively large surface area of the article, which is preferably shaded, colored, or otherwise highlighted to illustrate the irregularities that are formed therein. The single comprehensive enlarged visual representation can be used to analyze the nature of such irregularities.

A nondestructive method and apparatus for the inspection of impact treated surfaces to predict impact treatment process variables which acquires a multi-dimensional map of an impact treated surface, characterizes the multi-dimensional map to develop surface texture parameters, and develops relationships between the surface texture parameters and the impact treatment process variables.

A method for storing elastic bands makes use of an annular storage device, larger in diameter than the unstretched length of the elastic bands to be stored. The device has a series of clogs around its circumference, thereby creating a recessed area between each pair of adjacent clogs. The elastic bands to be stored are sequentially applied to the device, each elastic band being stretched between diametrically opposed recesses, thereby spanning the center. The elastic bands are then later removed in reverse order, as needed.
