Abstract: Revision of a part specification document, such as a drawing, a part specification, or a bill of materials, prompts execution of an automated notification process. A unique part number associated with the revised part specification document is employed in searching open purchasing documents for purchase orders or request for quotes containing the part number. Electronic mail addresses for outside supplier contacts are kept in the database and linked to the supplier master of the open purchasing documents containing the part number. An electronic mail notification of the part specification document revision is generated and transmitted to each electronic mail address identified as being associated with an open purchasing document containing the subject part number.

Abstract: A charge-transfer voltage converter transforms a high voltage to a lower value without the use of a conventional transformer. Two capacitors are connected together to form an electrical circuit. The circuit is then broken in one place and a switch is inserted to form a continuous circuit. One of the two capacitors is charged to a high voltage. The switch is turned on and off rapidly and this transfers a charge from the charged capacitor to one which was initially uncharged. By controlling the duty cycle and/or repetition rate of the switch between the two capacitors, the output voltage of the capacitor which was initially uncharged can be maintained between the limits of zero volts and the value to which the supplying capacitor was initially charged. Thus, voltage transformation has been achieved without the use of a conventional transformer.
