A device for transport of air in the tire P or close to it consisting of a chamber K in the shape of a hollow compressible channel, placed along at least a part of the tire perimeter, characterized by the fact that a ring OK is placed at the inner side of the chamber K with the distance of its outer side from the tire axis of rotation equal to 1 to 1.1 multiple of the distance of the bottom side of the chamber K from the axis of rotation of the tire P.

A method of intelligently controlling power generation based on an efficiency map may include performing a power generation control selection mode in which voltage change speed control is performed based on a load map or a driving torque map of an alternator after power generation control of the alternator is performed by a controller while a vehicle travels.

A support structure for a vehicle roof panel includes a solar panel module. The solar panel module is disposed within an opening defined by an outer periphery of a support structure. The solar panel module includes a first part configured to slide underneath a second part containing a solar array adhered to a flange. The flange has a plurality of ribs extending across the solar array. The ribs have a V-shaped cross-section to support the solar panel module within the second part.

A light emitting device for an automobile wheel, is capable of generating electrical energy through torque of an automobile wheel, illuminating an advertisement member using the generated electrical energy, and controlling the advertisement member to display advertisement contents at a correct posture without being tilted in response to a reverse magnetic field generated during the electricity generation process.

A system for distributing auxiliary power onboard of a train including a first car, a second car, and a third car equipped each with electric loads, including: a power distribution line extending across the cars; a first, a second and a third auxiliary power generators each configured to supply power to the electric loads on the first, second and third cars, respectively; a first and a second auxiliary power switching devices positioned along the power distribution line between the first and second auxiliary power generators and between the second and third power generators, respectively; a third and a fourth auxiliary power switching devices positioned along the power distribution line at the second car. When one of the auxiliary power generators is faulty, loads installed on the car affected by the faulty generator are supplied by one of the other auxiliary power generators via switching of the power switching devices.

Systems and methods are disclosed for providing a work vehicle with an auxiliary air conditioner and/or an auxiliary heater. The systems include power conversion circuitry configured to convert AC power from an AC power source to power conditioned to drive the auxiliary air conditioner and/or auxiliary heater. The AC power source may be configured to drive various loads, and accordingly may include control circuitry to manage the power provided to the various loads, including the auxiliary air conditioner and/or auxiliary heater.

A power generation system is provided configured for installation within a wheel of a vehicle. The system includes a stator having a plurality of face-mounted permanent magnets; and a rotor having a plurality of windings configured to rotate, with rotation of the wheel, in proximity to the permanent magnets thereby generating a current. The stator is mounted to a brake caliper of the vehicle. Also provided is a wheel-based vehicle display system including a light emitting diode (LED) array arranged on or within a wheel of a vehicle; a power source connected thereto; and a controller connected to the LED array. The display system is configured to display at least one of: textual information, visual images or full-motion video.

A mixer drum driving apparatus having a mixer drum carried on a frame of a mixer truck to be free to rotate and a drive source configured to drive the mixer drum to rotate includes a rotary motor configured to drive the mixer drum to rotate as the drive source, a power supply configured to supply power to the rotary motor, and a power generator configured to generate power as the mixer drum rotates and charge the generated power to the power supply.

A multi-functional active container (e.g., luggage or suitcase) with a plurality of sensors and actuators is described. The container may include a body defining an enclosure and having at least one opening. The container may include a processor, a wireless receiver, and an electronically controllable lock. The processor can selectively lock or unlock the electronically controllable lock based on signals received via a wireless receiver (e.g., via Wi-Fi or BLUETOOTH connections). In some examples, a distance between the active container and a remote device (e.g., a smart phone) can be determined (e.g., based on relative GPS signals or connection strength) and if the distance exceeds a threshold, the electronically controllable lock can be activated to secure the container. Further, the container may include a rechargeable power source for powering external devices and an integrated weight sensor for detecting the weight of the container.
