Abstract: A smart Electric Vehicle Supply Equipment (“EVSE”) that will accept input from different sources to determine the max rate of charge an Electric Vehicle (EV) can be safely charged at without overloading the electrical system of the residence. The system will also communication signals from the power company, fire department and police to reduce or eliminate the charging of the battery in the EV if the situation requires. The smart EVSE further comprises a non-invasive current and/or load sensing unit coupled to the power source for recharging the battery or batteries in the EV, cables to connect the load sensing unit to the EVSE, and optional wireless communication transmitter (sensor to EVSE), EVSE unit with compensating ability.

Abstract: The various implementations of the present invention provide a high efficiency “wye” rotor hub that is introduced into the airflow of the compressed air as the compressed air is delivered to the blades of the helicopter. The hub assembly has a plurality of hollow tubes that more efficiently guide the compressed air into the hollow blades, thereby improving the efficiency and performance of the engine. The hollow rotor tube hub insert looks much like a “ram's horn” where the flow area of the compressed air entering the hollow mast from the air compressor is diverted equally into a plurality of generally circular tubes, with each tube having a substantially equal cross-sectional diameter and area and where the number of circular tubes is equal to the number of rotor blades.
