A system includes a wheel including a center cap having a first portion configured to rotate with the wheel and a second portion configured to remain stationary. The second portion includes a light source and a power storage module. The system further includes a generator configured to generate power and output the power to at least the power storage module, a power converter coupled between the power storage module and the light source, and a control module. The control module is configured to receive a signal indicative of a key associated with the vehicle being within a defined distance, and in response to receiving the signal, control the power converter to output the power generated by the generator and stored in the power storage module to the light source. Other examples systems and methods for controlling a light source in a wheel of a vehicle are also disclosed.

A vehicle wheel-based computing device includes a display device that can be at least partially attached to a wheel of a vehicle, and a control circuit. The control circuit can obtain content to be provided for presentation on a display screen of the display device, receive vehicle data indicating a motion parameter associated with the vehicle, and perform a transformation of the content based on: (i) a refresh rate associated with the display device, and (ii) the motion parameter associated with the vehicle.

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 wheel includes illumination built into the wheel, such as one or more LEDs disposed within the wheel itself. Unlike add-one lighting accessories, the LEDs may be integrated with the wheel to avoid disconnection from the wheel. The wheels can include a centrally located power supply and a switch. An optional cover may be disposed over the wheel. With the LEDs formed into the wheel, the optional covers may be flush with and shaped in a shape to match the wheel. The wheels may be wheels from cars, trucks, trailers, recreational vehicles, all-terrain vehicles, motorcycles and the like. When the wheel may be visible from both sides, as in the case with motorcycles, the LEDs may be disposed and integrated in both sides of the wheel.

An apparatus for noise reduction of a tire reduces noise within a particular frequency range generated in the tire during operation of a vehicle. The apparatus includes a housing mounted on a wheel rim, the tire being fitted over the wheel rim, and the housing having an inner space; a resonant cover provided in the inner space of the housing; and a resonance hole formed in the resonant cover to allow the inner space of the housing and an inside of the tire to communicate with each other so that the resonant cover controls pulsation via air entering and exiting through the resonance hole.

Device for maintaining the orientation of an emblem in an automobile wheel includes maintaining the emblem in a substantially vertical orientation. Maintaining the emblem in a substantially vertical orientation comprises a detection component for detecting the orientation of the emblem. The emblem also comprises a motor provided with an output shaft. The output shaft of the motor rotates integrally with the emblem such that the motor rotates the emblem to place it in a substantially vertical orientation depending on the orientation of the emblem detected by the detecting component.
