Abstract:
A method of controlling and a system for charging a battery power supply unit for a bicycle electronic device, even in critical temperature conditions, is provided. Heat energy is supplied to the power supply unit when its temperature is lower than or equal to a lower temperature threshold within a closed charging temperature range characteristic of the power supply unit.
Abstract:
A bicycle-implemented transmission method is applied in a transmitter electronic component of a bicycle electronic system. The system includes at least one receiver electronic component, each system component having zero or more pieces of information attributable thereto and candidate to communication within the system. Each of the attributable pieces of information includes an identifier which is unique in the bicycle electronic system. According to the method, basic-payloads, each containing at least the unique identifier of a respective one of the attributable pieces of information, are formed and grouped together in a payload. The payload is then sent to the at least one receiver electronic component as value of a characteristic of a Bluetooth Low Energy (BLE) service.
Abstract:
A bicycle-implemented transmission method is applied in a transmitter component of a bicycle electronic system. Each component of the system has zero or more pieces of information attributable thereto and is candidate to communication within the system. Each of the attributable pieces of information includes an identifier which is unique in the bicycle electronic system. According to the method: a payload is formed, including an attributable piece of information and an identifier of an instruction executable by an addressee component; a value of a characteristic of a Bluetooth Low Energy (BLE) service of a Generic Attribute Profile (GATT) server of a BLE network architecture is set to the payload; and the characteristic is transmitted to the addressee component or to a receiver component to which the addressee component is directly or indirectly connected.
Abstract:
A detector for a bicycle that includes a magnet, which generates a generated magnetic field, and a magnetic field sensor. The mutual position of the magnet and of the sensor is fixed, and the sensor is immersed in the generated magnetic field. A length of a path intended for a non-diamagnetic movable element is immersed in the generated magnetic field; if in said path length there is at least one actual portion of the movable element, the sensor detects the magnetic field perturbed by the actual portion of the movable element. Bicycle equipment and a bicycle derailleur are also described.
Abstract:
A bicycle wireless electronic derailleur, comprising a support body, a movable body, comprising a chain guide, actuation means configured to move the movable body with respect to the support body, comprising an electric motor, a controller of the electric motor, a wireless communication device, part of or in communication with the controller, configured to receive gearshifting request signals from a wireless transmitter and housed in a first casing, and a bicycle movement detector configured to emit a wake signal for the wireless communication device. The movement detector is at least partially housed in at least one second casing different from the first casing, and is in communication through at least one cable with the wireless communication device.
Abstract:
A bicycle-implemented communication method is applied in a first electronic component of a bicycle electronic system. The first electronic component is connected with a second electronic component in a Bluetooth Low Energy (BLE) network, and with a third electronic component in a non-BLE network. The method includes steps al-a3 and/or steps b1-b3 of: a1) receiving from the third electronic component a data packet having a payload according to a non-BLE communication protocol; a2) setting to the payload a value of a characteristic of a GATT service; a3) transmitting the characteristic to the second electronic component; b1) receiving a characteristic of a GATT service from the second electronic component, the characteristic having a value; b2) encapsulating the value as payload in a data packet according to a non-BLE communication protocol; and b3) transmitting the data packet to the third electronic component.
Abstract:
A bicycle electronic equipment configured to be attached to a location of the bicycle includes a data processing system, a multicolour light source, and a switch. The switch includes a push-button and a two-state electric circuit. The data processing system is configured to: (a) make the light source emit cyclically repeating N coloured light emitting patterns, with N>=3, wherein coloured light emitting patterns immediately consecutive in the cyclical repetition differ in color and/or type of emitting pattern; (b) monitor the state of the switch during execution of step (a); and (c) perform a different action among N different actions according to which of the N coloured light emitting patterns the source is emitting upon the state switching of the switch.
Abstract:
A method for controlling a motor of a derailleur of a bicycle electronic gearshift during a displacement from an initial position (A) towards a destination position (B) includes the step of feedback controlling the current (I(t)) absorbed by the motor. A controller of an electric motor of a derailleur of a bicycle electronic gearshift is configured to carry out a feedback control of the current (I(t)) absorbed by the motor during a displacement from an initial position (A) towards a destination position (B).
Abstract:
An electronically servo-assisted bicycle gearshift is disclosed, comprising a derailleur and control electronics to drive the derailleur in accordance with a table of command values, wherein the derailleur is configured to emit a derailleur model identification signal, and the control electronics is configured to receive the derailleur model identification signal and, if it has an available table of command values suitable for the derailleur model, to use it to drive the derailleur, if not, to prevent the actuation of the derailleur.
