Abstract: A device and method for rated voltage detection and charging of electric batteries. The method comprises the steps of measuring a terminal voltage of the battery having first or second rated voltages, comparing the terminal voltage to a number of threshold voltages between a minimum threshold voltage and a maximum threshold voltage, determining a condition of the battery, which can be ready to charge or fault, based on a comparison of the terminal voltage to the threshold voltages, determining that the rated voltage of the electric battery is the second rated voltage if the determined condition of the electric battery is ready to charge, conducting a pre-charge process if the determined condition of the battery is neither ready to charge nor fault, determining the rated voltage of the electric battery based on a response to the pre-charge process, and charging the electric battery according to the determined rated voltage.

Abstract: Embodiments disclosed herein provide methods and systems for auto-voltage detect chargers. One disclosed method comprises the steps of determining a condition of a battery based at least in part on a measured response to a predetermined test charge; and determining a voltage rating of the battery based at least in part on the condition of the battery and a response to a precharge process.

Abstract: A windshield wiper comprises a wiper blade including a squeegee portion for contacting a surface and a body supporting the squeegee portion. A primary spline is engaged with the body and has a first closed end and a second open end. A support structure is provided to attach the wiper to a wiper arm on a vehicle. At least one spoiler is slidingly disposed on the primary spline above the secondary spline. A secondary spline is slidingly disposed between the body and the support structure, whereby the secondary spline is retained in place by caps disposed at the first and second ends of the primary spline. The secondary spline is removably disposed between said wiper blade and said support structure and retained in place by end caps.

Abstract: A windshield wiper frame connector assembly for a windshield wiper assembly for motor vehicles which accommodates different size wiper arms, wherein the assembly accommodates connectors adapted to receive regular and large hook type wiper arms, pin type wiper arms, reverse hook arms, or straight and two-hole bayonet type wiper arms. The wiper blade frame is designed to accommodate a majority of commercial vehicle wiper arms.
