A method and corresponding system for updating or installing new software loaded into the memory of an implantable medical device implanted within a body of a patient is described. Accordingly, the electric circuit parts are prevented from being damaged andor burnt by the electrical discharge and the high-voltage generator is miniaturized. Digit currents are provided in parallel in the digit lines at substantially the same time as the bit line current. The valve may provide a desired discharge of refrigerant from a sump oil accumulation while controlling sump pressure and loss of the oil. The system may present query refinement options, the query refinement box being populated with the prior search queries as suggested queries for possible selection by a user, the identified possible spelling corrected search queries, and the received query completion suggestions. The injection port is configured for localized coupling and injection to the corresponding product dispenser.
