Abstract: An apparatus and method for automatic balancing and inertial damping of vibrations in a rotor are disclosed. According to one embodiment, a rotor drive shaft is adapted to mount a rotor and rotate the rotor. A lower drive shaft connects to a source of rotation. A flexible coupling attaches the rotor drive shaft to the lower drive shaft and transfers a rotational force applied by the source of rotation to the rotor while permitting relative lateral motion between the rotor drive shaft and the lower drive shaft. An inertial coupling is coupled to the rotor drive shaft and provides inertial resistance to the relative lateral motion. A clamping collar is coupled to the inertial coupling to couple the inertial coupling to a chassis and permit the relative lateral motion between the rotor drive shaft and the lower drive shaft.

Abstract: An energy information system and sub-measurement board for use therewith allows an energy information service provider to measure energy usage at a customer location. The sub-measurement board is connected to an energy distribution panel located at the customer location and measures energy usage of individual circuits of the distribution panel. The sub-measurement board outputs a load profile that is accessible by the customer. The sub-measurement board receives three three-phase voltages and nine single-phase currents. The voltages and currents are compared to the voltages and currents of the same individual circuit of the distribution panel to calculate the load profile of the individual circuits. A utility meter can be connected to the sub-measurement board and output electric pulses thereto which the sub-measurement board uses to calculate cumulative periodic consumption data of the metered utility.

Abstract: A plurality of semiconductor devices are provided on a carrier for testing or burning-in. The carrier is then cut up to provide single chip-on-carrier components or multi-chip-on-carrier components. The carrier is used as a first level package for each chip. Thus, the carrier serves a dual purpose for test and burn-in and for packaging. A lead reduction mechanism, such as a built-in self-test engine, can be provided on each chip or on the carrier and is connected to contacts of the carrier for the testing and burn-in steps. The final package after cutting includes at least one known good die and may include an array of chips on the carrier, such as a SIMM or a DIMM. The final package can also be a stack of chips each mounted on a separate carrier. The carriers of the stack are connected to each other through a substrate mounted along a side face of the stack that is electrically connected to a line of pads along an edge of each carrier.
