  • Publication number: 20060244314
    Abstract: A power supply assembly for an electrical component whose largest load requirements during operation are intermittent includes a principal power supply for supplying the operating power for the electrical component for a major fraction of the period of operation of the electrical component yet is incapable of supplying the largest load requirements of the electrical component during the remaining and intermittent periods of operation of the electrical component. However, the power supply assembly further includes a plurality of ultra-capacitors for discharging electrical power to the electrical component during the intervals of time when the load requirements of the electrical component exceed the output capabilities of the principal power supply.

  • Patent number: 4934384
    Abstract: A tobacco pipe combustion maintenance accessory for maintaining continuous burning of tobacco in the bowl of a pipe once the tobacco is initially ignited. The device includes a generally flat body having a curvilinear concave reflective surface on one side of the body. When the body is held above the pipe bowl, the curvilinear surface, properly positioned, reflects heat and light waves emitting from the portion of burning tobacco back at the tobacco in focused or concentrated form to ignite the unlit portions of the tobacco at the point where the reflective rays focus. By manipulation of the device in very close proximity above the rim of the pipe bowl so that the rays are reflected downardly into the tobacco, the collected rays at their point of focus maintain the tobacco burning. The curvilinear surface is preferably a spherical segment and may also be structured similar to a fresnal lens having reflective concentric surfaces to achieve relative flatness and a shorter focal length.
