Abstract: The present application relates to a device for treating skin (1) comprising a housing (2), a shaft (14) located in the housing (2) having a longitudinal axis (‘A’) and an end for receiving a skin treating part (3). The device (1) further comprises a drive means configured to cause the shaft to rotate about its longitudinal axis, and to oscillate in a direction along the longitudinal axis, wherein the drive means comprise a rotational drive unit for rotating the shaft (14) and an oscillation generator (26) for oscillating the shaft. The oscillation generator (26) is located about the shaft (14) such that the shaft is rotatable relative to the oscillation generator. Furthermore, the oscillation generator (26) comprises a solenoid (39) and a flux assembly (25), and the flux assembly (25) is moveable along the shaft (14) relative to the solenoid (39).

Abstract: A device for storing optical discs is disclosed. The device includes a housing, a carousel arranged in the housing for movement relative to the housing, the carousel having a plurality of storage compartments each for storing a disc, an opening in the housing through which a disc can pass, drive means for driving the carousel relative to the housing to align each of the storage compartments and a disc stored in that storage compartment in registry with the opening, and an ejection system to eject a disc from a storage compartment and through the opening in said housing. The ejection system is powered by a motor and a clutch system, and control means is provided to cause said carousel to rotate and to cause the ejection system to operate as instructed by a user.

Abstract: The present invention relates to the field of sensing apparatus (10) in detecting particles in air sampled from a number of locations. In one aspect the present invention provides for the determination of the time of flight of a signal transmitted between a transmitter (42, 44) and a receiver (44, 42), comprising: transmitting a first signal comprising at least one characteristic waveform feature; transmitting a second signal comprising at least one characteristic waveform feature and a waveform modification introduced at a predetermined point in time of the duration of the second signal; receiving said first and second transmitted signals; determining a point of diversion between corresponding characteristic waveform features of the first and second received signals comprising super positioning said first and second received signals such that said point of diversion corresponds to an arrival time of the introduced waveform feature modification at the receiver.
