Abstract: In summary, the present invention relates to a device, a method and a computer program enabling a rotating and translating movement by means of a single motor. An electric motor (102) for linear and rotary movement can comprise a stator (104) having a multi-phase coil arrangement including a number of coils or coil sets and a rotor (106) being movable along a direction of its rotational axis and having a number of poles respectively comprising at least one permanent magnet. A control unit (108) may determine currents based on at least the number of coils or coil sets, an angle of rotation of the rotor and a parameter depending on an axial position of the rotor, and supply the determined currents to the coils or coil sets.

Abstract: An apparatus for determining roll angle of a motorcycle (1) as when taking a curve or bend in a road. The apparatus includes a first gyro sensor (11) that provides a roll rate signal, a second gyro sensor (12) that provides a yaw rate signal, and a velocity sensor (36). The apparatus is configured to integrate the roll rate signal to obtain a first intermediate roll angle value and to determine a second intermediate roll angle value from the yaw rate and the vehicle velocity. The apparatus combines the two intermediate roll angle values into an output value for the roll angle that can be used by a servo (50) to adjust the orientation of the headlamp so that the beam pattern remains leveled with the horizon when the motorcycle (1) rolls when taking a curve.

Abstract: An inductive transmission system for inductive transmission of power and full duplex data signals between first and second devices. The transmission system includes a bi-directional inductive channel between the two devices; a transmitter for transmitting a power signal at a first frequency from the first device to the second device over the inductive channel; a first modulating device for modulating a first data signal at a first modulation frequency; and a second modulating device for modulating a second data signal at a second modulation frequency. Further transmitters transmit the modulated first data signals from the first device to the second device over the inductive channel, and transmits the modulated second data signals from the second device to the first device over the inductive channel. The first modulation frequency and the second modulation frequency are at least a factor two apart.
