This invention relates to a rotatable device having two arms rotatably connected about a hollow hub wherein the arms include a cable extending through a passageway and the hub so as to minimize bending of the cables about each other when the arms are in a compact position. In particular this invention relates to a foldable GPS compass and a method relating thereto to present a compact folded device that is easier to install with minimal bending of the cables. The invention also discloses a detent disposed within the hub for accurate selective placement of the arms and method relating thereto.

The invention relates to a non-axial working End-of-Content mechanism which is geared by a hypocycloid gearing. The EoC mechanism comprises a first element (30, 109) having a first internal surface (36, 136) with a first internal diameter (D), and an EoC element (50, 150) having a second external surface (56, 156) with a second external diameter (d) being smaller that the first internal diameter (D). The EoC element (50, 150) is located inside the first internal diameter (D) of the first element (30, 109) and the first element (30, 109) and the EoC element rotates relatively to each other in a gearing ratio. The EoC element (150, 150) thus operating as the inner rolling circle of a hypocycloid counting the numbers of relative rotations. The EoC mechanism further has stopping means (45, 55; 113, 155)) provided for stopping the relative rotation in a predetermined position which position correlates to the initial injectable content of drug in the injection device such that a user cannot at any time set a dose larger than the quantum left in the injection device at any time.

An electrical steering column lock for an automotive vehicle capable of locking and unlocking the steering column is disclosed. The electrical steering column lock includes a bolt intended to move for locking and for unlocking the steering column, a cam wheel intended to rotate according a first rotation axis and to cooperate with the bolt for controlling the bolt movement, and an assembly for determining the rotational position of the cam wheel while the cam wheel is rotating.
