Abstract: Input devices such as satellites, field sensors, electronic pads, cellular phones, and/or radio transmitters communicate information representing queries, reports, and/or instructions to an intention determination system that is accessible by a user interface with a display. The intention determination system includes an input module for processing the information received from the input devices; a language converter for converting the information from a natural language format to a restructured form in a position-based format; a database system for storing the received information, the restructured information, and reference information; and a rule-based analyzer for periodically retrieving and processing the stored information. The analyzer sends an alert to the user interface to notify the user if execution of one the instructions creates a potential conflict with the other stored information.

Abstract: A rechargeable battery having a user-selected charge capacity whereby a user of the battery can select the voltage at which the battery is charged, and thus can control the capacity of the battery. The battery has a rigid casing with an exterior surface thereof, and a rechargeable electrochemical cell within the casing. A plurality of charge contacts are accessible at the exterior surface of the casing and are in conductive contact with the electrochemical cell to allow charging of the electrochemical cell when a current is placed across the charge contacts. The battery also has a charge control circuit in conductive contact with at least the charge contacts and the electrochemical cell, and the control circuit includes a voltage regulator that regulates the charge voltage from the charge contacts to the electrochemical cell.

Abstract: A disclosed tool provides convenient use thereof. In a described embodiment, a refrigerant charging tool has two separately formed handles pivotably attached to each other. One of the handles has a container piercing member mounted thereon. A spacer is configured for attachment to the other handle, so that a relatively small container may be biased against the container piercing member when the handles are pivoted toward each other.
