An earpiece includes an earpiece housing, a processor disposed within the ear piece housing, at least one inertial sensor disposed within the earpiece housing, the at least one inertial sensor operatively connected to the processor, and a wireless transceiver disposed within the earpiece housing and operatively connected to the processor. The earpiece is configured to exchange inertial data with a vehicle having one or more inertial sensors. The vehicle may be a motorcycle, moped, scooter, bicycle, electric bicycle, personal transporter, hover board, or other type of vehicle.

The present invention relates to a multifunctional lighting apparatus for a bicycle, which includes: a lighting apparatus ascending/descending support unit detachably mounted on a steering unit of a bicycle; an ascending/descending movement body part vertically movably located in the lighting apparatus ascending/descending support unit; and a main lighting lamp unit located in the ascending/descending movement body part and irradiating light, and as a result, a lighting lamp unit can be located at a position desired by a driver by adjusting a height of the lighting lamp unit, thereby enhancing both satisfaction and safety in use.

A vehicle includes a control switch that is configured to generate an operation signal, and a controller that is electrically connected to the control switch to receive the operation signal therefrom, and that is configured to, in response to receipt of the operation signal, transmit a control signal to a tilting mechanism for making the tilting mechanism operate in one of a locked state and an unlocked state. After the vehicle is powered on, the controller is further configured to, when the controller has continuously received the operation signal for a predetermined reception time, determine that the control switch is abnormal, stop transmitting the control signal and control a warning unit to output a warning signal.

A hydraulic disc braking system is disclosed. The system has a manually operated control device for a cyclist to issue a braking command. The system has a master cylinder assembly having a membrane dividing the hydraulic fluid tank into a variable volume filled chamber and a complementarily variable volume empty chamber. A membrane detector senses the presence of the membrane relative to a predetermined position in the tank and/or a meter measures the distance of the membrane from the ceiling of tank.

A diagnostic method for a bicycle hydraulic disc braking system, having a master cylinder assembly with a cylinder inside which a piston reciprocates against the action of a return spring. The master cylinder has a hydraulic tank with a bottom, a ceiling, and a membrane that divides the hydraulic tank into two chambers. The hydraulic tank is connected to the cylinder through the bottom. A metering device measures the distance between the membrane and the ceiling of the tank. The output signal of the metering device is evaluated to determine that operation is correct when the membrane temporarily approaches the ceiling by a predetermined extent range, or incorrect otherwise. A positive evaluation reflects the correct operating condition, and a negative evaluation reflects an incorrect operating condition.

A notification system for an electric power assisted vehicle includes two or more notifiers to notify a user that a remaining charge of a battery that supplies power to an electric motor is low, and a controller configured or programmed to control operations of the two or more notifiers. The two or more notifiers include two or more of a display panel to display the remaining battery charge, a lamp to emit light, and a sound component to produce sound. The controller is configured or programmed to compare the remaining battery charge with a predetermined value, and when the remaining battery charge is lower than or equal to the predetermined value, to notify the user that the remaining battery charge is low by a combination of the operations of the two or more notifiers.

An electric vehicle assembly includes an electric vehicle and a processing device. The electric vehicle includes a wheel, and an electric motor configured to drive the wheel to rotate and to output a value of torque force applied on the wheel and a speed measurement of the electric vehicle. The processing device stores a vehicle weight, and receives a value of torque force and two speed measurements of the electric vehicle from the electric motor, obtains an acceleration based on the speed measurements, obtains a current user weight based on the value of torque force, the acceleration and the vehicle weight, and outputs a notification when the current user weight is lower than an initial user weight by a predetermined ratio.
