Hybrid trailer system
InactiveUS20080169144A1Easily retrofit into new and used trailerReduce maintenanceAuxillary drivesConvertible cyclesCapacitanceCapacitive storage
A system and related method for a regenerative braking system on a towed vehicle, such as a trailer or semi-trailer. The system provides power and braking to the respective trailer wheels, as needed, to help stabilize the trailer. Power is regenerated during braking. While batteries may be used to store the energy, the system also may use capacitive storage units, which charge and discharge large amounts of energy at a fast rate. A multiple-axis sensor system in conjunction with wheel sensors, load sensors, and proportional control of the brakes and motor power to the axles and wheels, is used to achieve superior load stabilization. The invention can be easily retrofit into new or used trailers, and is self-contained with low maintenance.

Self Heating Battery System
ActiveUS20120126753A1Supply will become excessiveHigh switching rateBatteries circuit arrangementsSecondary cellsCapacitanceCapacitive storage
A battery self heating system for batteries that experience battery impedance or internal battery resistance when temperature drops. The system comprises an energy storage element applied to the battery terminals to draw energy from the battery. The energy is stored in a magnetic or capacitive storage device. The system is self-resonant so that energy transfer from the storage device to the battery will occur at a frequency and load level that is compatible with the current state of the battery. Internal heating of the battery is accomplished by a cycle comprising the out flux and influx of energy through the impedance of the battery. Energy losses due to battery impedance are converted to heat thereby heating the battery internally.

Cascaded switching power converter for coupling a photovoltaic energy source to power mains
InactiveUS20110032734A1High energyLarge outputAc-dc conversionSingle network parallel feeding arrangementsCapacitanceCapacitive storage
A cascaded switching power converter for coupling a photovoltaic (PV) energy source to power mains provides a high-efficiency and a potentially simple control mechanism for AC solar energy conversion systems. The PV energy source charges a capacitive storage element through a DC-DC converter, and an inverter couples energy from the capacitive storage element to the mains supply. The DC-DC converter is controlled so that ripple present on the capacitive storage element due to current drawn by the inverter is not reflected at the input of the DC-DC converter, which is accomplished by varying the conversion ratio of the DC-DC converter with the ripple voltage present across the capacitor. The average voltage of the capacitor can also be increased with increases in the available power output from the PV energy source, so that a corresponding increase in power is transferred to the mains supply.

Each of the data objects is stored in non-volatile memory. The dynamic data objects and static data objects requiring frequent access are stored in volatile memory. A record of static data objects is maintained in non-volatile memory and a record of dynamic data objects is maintained in volatile memory. Upon power loss, the present value of each dynamic data object is copied to non-volatile memory. When power is restored, the values of both the dynamic data objects and the static data objects that require frequent access at run-time are copied from non-volatile memory to volatile memory.
