Abstract: Systems and methods for improved operation of hand tools are disclosed. Sensors may be configured to monitor one or more operational parameters of a hand tool and collected data may be communicated to the hand tool operator. The data may be compared to predetermined limits for an operational parameter to enable real-time operational diagnostics and quantitative control. Data can be collected across a manufacturing facility and analyzed to help account for variations in technique and skill among operators. An understanding of relationships between monitored operational parameters can lead to improved consistency among finished products and reduction in manufacturing costs. Data may also be stored for future recall and analysis.

The process comprises the successive application of at least two free-flowing compositions which comprise nanoscale inorganic solid particles comprising at least one of a polymerizable and a polycondensable organic group to a surface of the crystalline substrate and the polymerization and/or polycondensation of the organic groups of the solid particles to form organically crosslinked layers on the substrate and a single-stage thermal consolidation of these layers with a burnout of organic constituents thereof. The at least two compositions give rise to layers with different refractive indices.

Abstract: A linear motion electrical connector includes an outer component having a bore defined by an inner surface and a cylinder within the bore. The cylinder has an outer surface. An annular groove is formed on one of the outer surface of the cylinder or the inner surface of the outer component. The annular groove has an axial length. A conductive spring is fit within the annular groove and provides electrical contact between the outer component and the cylinder. The conductive helical spring is adapted to roll along the axial length of the annular groove to maintain electrical contact when the cylinder is translated relative to the outer component.
