Abstract: A method for operating a drive unit of an electric bicycle is disclosed. The method includes: determining a cadence of a crank drive of the electric bicycle, and operating the drive unit in a controlled manner to generate a drive power as a function of the determined cadence and on the basis of a power characteristics map of the drive unit. The power characteristics map includes a power characteristic curve which defines a predetermined relationship between the drive power of the drive unit and the current cadence, and the power characteristics map includes a maximum power range within which the power characteristic curve defines a maximum drive power of the drive unit. The maximum power range is within a cadence range that can be set by a rider of the electric bicycle.

Abstract: A drive system of a vehicle which is operable using muscular energy and/or motor power. The drive system includes a drive unit and a frame interface, the drive unit being at least partially situated between a first wall and a second wall of the frame interface. The drive system further includes a holding device, which holds the drive unit on each of the two walls, the holding device being fixed in place on the second wall; and a tolerance compensation element. The first wall has a first wall opening. The tolerance compensation element is developed in the form of a sleeve and is situated inside the first wall opening. A part of the holding device is disposed inside the tolerance compensation element in an axially movable manner.

Abstract: An electronic device includes a frame and a battery. The frame is configured to be worn on a user's body. The battery is supported by the frame and includes a first cell and a second cell in electrical parallel. The first cell has a first capacity and the second cell has a second capacity that is different from the first capacity.

Abstract: A measurement assemblage for measuring the torque on a shaft, and in particular the torsional moment of the shaft, having a sensor device that is configured to measure a magnetic field carried or generated by the shaft; a sensor holder for holding the sensor device and for disposing the sensor device with respect to a region of an outer circumferential surface of the shaft; and at least one force element that is configured to dispose the sensor holder, by force impingement, in stationary fashion with respect to the region of the outer circumferential surface of the shaft, the at least one force element being configured to exert a tensile force on the sensor holder in such a way that the sensor holder is pulled against the region of the outer circumferential surface of the shaft as a result of the tensile force.

Abstract: An enhanced parallel protection circuit is provided. A system using separate battery packs in a parallel configuration is arranged with multiple protection circuit modules (PCMs). The PCMs are configured to detect fault conditions, such as over voltage, under voltage, excess current, etc. The PCMs can be configured to control associated switches and/or other components. When a fault condition is detected by an individual PCM, the individual PCM transitions to a fault state, and the PCM triggers an output causing one or more actions, e.g., causing a device to shut down or isolate one or more components. In addition, by the use of the techniques disclosed herein, the individual PCM can generate a control signal that causes other PCMs to transition to a fault state. The individual PCM can also receive a control signal from another PCM to cause the individual PCM to transition to a fault state.

Abstract: Techniques for enabling multi-pack and component connectivity detection are provided. In some configurations, individual PCMs can test the connectivity between components of a device without the need to operate the components. For example, PCMs configured in accordance with the present disclosure can test the connectivity between a motherboard, a display circuit, a camera, and a number of battery packs without the need to operate the motherboard, display circuit, camera, etc. In some configurations, conductors that are part of cables and connectors used to connect the components can be used to determine the state of one or more connections. When a signal that runs through the conductors meets one or more criteria, the PCMs of a device cause a predetermined delay prior to enabling one or more components. By testing the connectivity between components before each component transitions to an operational state, other problems caused by faulty connections can be mitigated.
