Abstract: The invention relates to a powered wheelchair (100, 200) for transporting a person comprising a seat frame (40) for supporting the person, a pair of opposing drive wheel assemblies (20, 30) configured to drive said powered wheelchair (100, 200) and connected to the seat frame (40), and a supporting wheel assembly (50) arranged spaced apart from the pair of opposing drive wheel assemblies (20, 30) and connected to the seat frame (40). The pair of opposing drive wheel assemblies (20, 30) comprising a first drive wheel assembly (20) and a second drive wheel assembly (30). The first drive wheel assembly (20) includes a first driving wheel (24) having a first rotation centre (R1) and operatively connected to a first rotation mechanism (26) via a first linkage member (28), said first rotation mechanism (26) is operable to rotate said first drive wheel assembly about a first pivot point (P1), wherein said first rotation centre is offset from said first pivot point.

Abstract: A caster wheel arrangement for a powered wheelchair, the caster wheel arrangement comprising: a caster wheel module comprising: a wheel rotatably connected to a first linkage member, wherein the wheel is rotatably arranged about a first axis of rotation of the wheel; and a support element rotatably connected to the first linkage member through a joint configured to allow a rotation of the first linkage member relative to the support element around a second axis of rotation perpendicular to the first axis of rotation; a second linkage member connected to the support element at a third axis of rotation, wherein the third axis of rotation is essentially perpendicular to the second axis of rotation of the first linkage member, to allow rotation of the caster wheel module about the third axis of rotation, wherein the third axis of rotation passes adjacent to the second axis of rotation.

Abstract: A sensor for three dimensional detection of the position of a ball joint 1 in which two emitters 14-15 and two collectors 20-21 are located in the ball 4 and socket 5, respectively, of the ball joint 1, and at least one more emitter or collector is located in either the ball 4 or socket 5. Each of the emitters emits a unique signal characteristic and each of the collectors detects and decodes the signals from all emitters. By analyzing the influence of all the emitters on each of the collectors, the position of the ball joint can be deduced. The emitters can be coils or light emitting diodes that emit unique signal frequencies and the collectors can be coils or photo transistors which detects the ratio of signals from each of the emitters. Alternatively, a rotating magnetic field can be induced by three emitter coils in one of the joint halves and detected by three collector coils located in the other joint half.
