Patent number: 11915259Abstract: A computerized system for transacting the purchase and sale of consumer motor fuels between motor fuel merchants and retail consumers through software on a mobile or desktop connected device for periods in the future through the simultaneous execution of multi-party, multi-layered contingent transactions and pricing algorithms to ensure that all inter-related motor fuel merchant transactions are simultaneously transacted upon a retail consumer purchase execution. Motor fuels include refined products such as gasoline and diesel fuel, renewable fuels (e.g. ethanol, biodiesel), natural gas (including liquefied natural gas), jet fuel and electricity.Type: GrantFiled: September 2, 2021Date of Patent: February 27, 2024Assignee: Gasmart, LLCInventors: Joseph H. LeBlanc, Jr., Nick DiCosola, Sagy P. Mintz, Leo E. Murphy, Robert A. Miller, William K. Ward, William F. Kerins, Luis R. Luque, Parker P. Drew, James V. Blanton

Patent number: 6831544Abstract: A method and apparatus to layout planar magnetic coils on a PCB consists of maximizing the layer to layer overlap, and consequently maximizing total inductance for the given layout area, by spiraling alternating layers inward and outward. A further benefit of the matching opposite spirals is the ability to make the layer to layer electrical contacts within the magnetic field area, thus reducing leakage inductance, and minimizing the wasted extra conductor line length needed to make the connections outside the magnetic field. The reduced conductor line length results in reduced conductor line resistance. The method is applicable to voltage transformers and isolation transformers as well as simple inductors and other magnetic devices. In the transformer case the odd numbered layers are typically connected together in series to provide a larger turn ratio, and the even numbered layers are typically single turns (i.e., no spiral) connected together in parallel to provide more current capability.Type: GrantFiled: October 9, 2003Date of Patent: December 14, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Raoji A. Patel, James E. Drew, Raymond A. Pelletier, Brian R. McQuain
