  • TRACTOR TRAILER REFRIGERATION UNIT
    Publication number: 20240131894
    Abstract: A reefer truck power unit employs a plurality of power sources including roof mounted solar panels, momentum generation, shore power and high capacity storage batteries. The refrigeration system is configured for refrigerating a payload area of the vehicle utilizing power from the power sources, and employs a voltage converter for augmenting the power from the propulsion vehicle source for use with a native vehicle charging//starting system, and a transport load transformer for converting power from the power sources to 3 phase power for powering the refrigeration system. A bank of batteries stores power from the sources for subsequent dispersal to the refrigeration unit.

  • Use of multiple laser sources for rapid, flexible machining and production of vias in multi-layered substrates
    Patent number: 6541731
    Abstract: A laser via drilling system, and a method of use thereof, is provided. The apparatus uses two or more laser systems to achieve processing parameter flexibility. The output beams from the independently controlled laser systems are combined using a beam splitter that combines the beams into single or multiple processing beams. The operational flexibility of the system can be further enhanced through the use of multiple EO modulators and a polarization sensitive beam splitter.
