Abstract: A treatment system for treating tissue is disclosed in which a handle with an elongate shaft projecting from the handle, a sheath axially slidable relative to the elongate shaft, and an electrode mounted on a proximal portion of the sheath is provided. A substrate having an elongate portion may be located within the handle. A plurality of first and second capacitive sensors may be positioned along the elongate portion. The electrode may be configured to slide along the elongate portion during movement of the sheath. The electrode may maintain contact with at least one of the first capacitive sensors at least one of the second capacitive sensors during movement of the sheath. The substrate may be configured to determine an axial position of the electrode based on a coupling capacitance caused by an electrode overlapping one or more of the first capacitive sensors and one or more of the second capacitive sensors.

Abstract: A hitching mirror for viewing a hitch at the rear of a towing vehicle includes a first panel having a lower reflective surface, a second panel with a suction cup for securing the hitching mirror to a rear window and an incremental adjuster for incrementally adjusting the position of the reflective surface relative to the hitch.

Abstract: A thin film photovoltaic panel includes a backcap for protecting the active components of the photovoltaic cells from adverse environmental elements. A spacing between the backcap and a top electrode layer is preferably filled with a desiccant to further reduce water vapor contamination of the environment surrounding the photovoltaic cells. The contamination of the spacing between the backcap and the cells may be further reduced by passing a selected gas through the spacing subsequent to sealing the backcap to the base of the photovoltaic panels, and once purged this spacing may be filled with an inert gas. The techniques of the present invention are preferably applied to thin film photovoltaic panels each formed from a plurality of photovoltaic cells arranged on a vitreous substrate. The stability of photovoltaic conversion efficiency remains relatively high during the life of the photovoltaic panel, and the cost of manufacturing highly efficient panels with such improved stability is significantly reduced.
