  • System and method for monitoring the state of charge of a battery
    Patent number: 8154252
    Abstract: A process for monitoring the status of a battery. Steps of the process include measuring a battery current and comparing the battery current to a predetermined threshold. A battery status is determined as one of charging, discharging and quiescent. For a battery charging status determination, the charging state of charge of the battery is computed. For battery discharge status determination, the discharge current is compared to a predetermined threshold. Based upon the discharge current comparison, a basis for the discharge current is selected from one of a plurality of predetermined discharge conditions and the discharging state of charge of the battery is computed for the select discharge condition. For a quiescent status, the quiescent state of charge of the battery is computed. The computed state of charge of the battery is provided in a quantitative form.

  • Self-Closing Barrier Screen
    Publication number: 20120025685
    Abstract: There is described a horizontally slidable self-closing screen assembly which comprises at least one screen material connected to a roller biasing the screen to an open position, the roller being operably connected to a counterweight and wherein the load provided by the weight is greater than the force provided by the roller biasing the screen. There are also described a housing unit containing the slidable screen assembly and a cabinet fitted with such a housing unit.
