IPC: H02J7/00
Filed: 2007-06-05
Abstract: A method of boosting a vehicle battery includes supplying a current to the battery, detecting an engine crank event, and, upon detecting the engine crank event, dynamically adjusting (i.e., first substantially increasing, and then decreasing) the current in response to battery voltage. The method may also include verifying a crank-ready condition in the battery by comparing one or more of battery voltage, battery current, and battery charge accumulation to respective crank thresholds. In certain embodiments, this verification step occurs only after a minimum charging time has elapsed, and may time out after a maximum charging time. Once the crank ready condition is detected, the operator may be so signaled. At the conclusion of the boost and crank cycle, the current to the battery may be interrupted and the engine status-started or not started-may be detected. The battery may also be monitored for error conditions.

IPC: B04C5/14
Filed: 2006-03-24
Abstract: A system and process for separating high and low density materials by air flow. Mixed solid material is delivered into an entrance of a cascade separation chamber where it is allowed to free fall and tumble over inclined surfaces. A fan forces air through a "closed" path that includes a duct from the fan outlet to return air to the separation chamber, and a branch duct that supplies an air knife disperser arranged to direct a high velocity air jet against free falling material in the chamber. The fan draws air that has entrained relatively light materials in the chamber, and thereby separates the same from the heavy materials, from the chamber through a duct connected to the inlet of an air cleaning device such as a cyclone separator. Cleaned air exhausted from the cyclone cleaning device and driven by the fan is continuously returned to the separation chamber. Air flow through the chamber is generally in counter-flow relation to the movement of heavy material through the chamber.
