  • Form factored and flexible ultracapacitors
    Patent number: 8274781
    Abstract: Advanced ultracapacitor construction of irregular shape is provided, having higher utilization of the available energy storage shape in various electronic and electromechanical products over the prior art ultracapacitors. Said irregular shape of ultracapacitor is achieved by using flexible and pliable cell materials in layers, blanked into any desired shape, and stacked. The layers may be also bent to follow any contour. More capacity in given irregular volume is thus accomplished.
    Type: Grant

  • Low cost conversion of any internal combustion vehicle into hybrid electric vehicle
    Publication number: 20080236910
    Abstract: This invention pertains to an economical method of easy conversion of any internal combustion fueled vehicle into a fuel saving hybrid electric vehicle (HEV) by an add-on kit, without replacing the engine and with a minimal modification of the vehicle body. The converted vehicle has a substantially longer driving range on the same amount of fuel than the vehicle before this conversion.
