  • Patent number: 11005292
    Abstract: A wireless power supply device comprises a transmitting coil assembly and a receiving coil assembly. The transmitting coil assembly includes a first ferrite core having a receiving chamber with an opening and a transmitting coil disposed in the receiving chamber of the first ferrite core. The receiving coil assembly is adapted to be moved into the receiving chamber through the opening of the receiving chamber and located at a predetermined position in the receiving chamber. The receiving coil assembly is electromagnetically coupled with the transmitting coil assembly.

  • Publication number: 20200328423
    Abstract: An anode includes a mixed ionic-electronic conductor (MIEC) with an open pore structure. The open pore structure includes open pores to facilitate motion of an alkali metal into and/or out of the MIEC. The open pore structure thus provides open space to relieve the stresses generated by the alkali metal when charging/discharging a battery. The MIEC is formed from a material that is thermodynamically and electrochemically stable against the alkali metal to prevent the formation of solid-electrolyte interphase (SEI) debris and the formation of dead alkali metal. The MIEC may also be passive (the MIEC does not store or release alkali metal). In one example, the open pore structure may be an array of substantially aligned tubules with a width less than about 300 nm, a wall thickness between about 1 nm to about 30 nm, and a height of at least 10 um arranged as a honeycomb.

  • Patent number: 6533446
    Abstract: A light, such as for an airport taxiway, in which a base includes a light source which outputs light. The light source may be an LED (light emitting diode) light source which is highly energy efficient and which has a long life. A light guide receives and guides light output from the light source. The light guide further extends out from the light source. A reflector is positioned in the light guide and reflects the light guided through the light guide to provide the appropriate illumination.
