  • Publication number: 20180232067
    Abstract: A navigation device with distance detecting function can utilize a distance detecting mechanism to detect a distance relative to a working surface. The distance detecting mechanism includes a base, a connecting component, a feature unit and a detection unit. The connecting component partly protrudes from the base. The connecting component optionally contacts against or is spaced from the working surface to generate a distance variation relative to the base along an axial direction. The feature unit is disposed on the connecting component. The detection unit is connected to the base. The detection unit can detect parameter difference of the feature unit according to the distance variation of the connecting component relative to the base, so as to determine the distance between the working surface and a bottom of the base via the parameter difference.

  • Publication number: 20180226231
    Abstract: Elastomeric components, such as a shoe outsole, are treated with a plasma application to clean and activate the elastomeric component. The application of plasma is controlled to achieve a sufficient surface composition change to enhance adhesion characteristics while not adversely physically deforming the elastomeric component. The plasma treatment is applied to increase carbonyl functional group concentrations within an altered region of the elastomeric component to within at least a range of 2%-15% of carbon atomic percentage composition. The cleaning and activation is controlled, in part, by ensuring a defined height offset range is maintained between the elastomeric component and the plasma source by a generated tool path. The elastomeric component may then be adhered, with an adhesive, to another component.
