Paul Lawson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7730883
    Abstract: An article for protecting the cam of a compound bow that includes a member extending from a limb of the compound bow and disposed in overlapping arrangement with the cam. The member extends beyond the cam such that the cam is elevated from a surface upon which the compound bow is placed. The member is positioned at an angle of greater than 0 and less than 180 degrees relative to the bow limb such that the member may be used as a stand and to provide vibration dampening functions.
    Type: Grant

  • Patent number: 4349775
    Abstract: A voltage regulator for use in photovoltaic charging of storage batteries includes a temperature compensated reference voltage. The circuitry of the invention permits fixed temperature coefficient and variable temperature coefficient temperature compensated regulation.The voltage regulator comprises an operational amplifier including a linearly temperature dependent current source coupled to an input terminal of said operational amplifier and a voltage source having a selectable voltage which is connected to another input of said operational amplifier, said reference voltage circuit being operable to provide a reference voltage about equal to a maximum charging voltage for said batteries;a comparator for comparing said reference voltage with an output voltage of said photovoltaic array; anda switch responsive to said comparator to inhibit charging whenever said array output exceeds said reference voltage.
