Abstract: One or more computers may close a purchase order by use of rules. Certain embodiments use values of attributes of a line in a purchase order (PO) to identify a rule among multiple rules. The PO line's attributes which are used to identify the rule are internal to a buyer. When the rule which is identified is disabled, the line is retained unchanged in the purchase order. When the identified rule is not disabled, a user-specified logic which is identified in the rule is used to determine a new value of a numeric term, the numeric term having a preexisting value previously agreed upon by the buyer and the seller, e.g. in units of quantity or units of money. Subsequently, an indication of the line being changed in the purchase order is transmitted to the seller. User may specify different logics in different sets of rules, for different business units.

Abstract: In an electrical power system of a diesel powered system having at least one diesel-fueled power generation unit, the electrical power system having a synchronous machine including a field winding being coupled to the diesel-fueled power generation unit, a battery for selectively providing a starting current during a starting mode of the electrical power system, and an inverter receiving the starting current for driving the synchronous machine and generating an inverter current, a circuit and method for reducing a voltage being developed across the field winding is described. The circuit includes a current conditioner for conditioning the inverter current and a parallel circuit interposed between the inverter and the current conditioner comprising a first branch including a resistance and a second branch including the field winding of the synchronous machine so that the parallel circuit is isolated from a voltage developed across the current conditioner during cranking.
