1. A rod-less cylinder device adapted to longitudinally displace loads, said device comprising: a shaft;a nut confined to move longitudinally within the shaft;a slider circumscribing said shaft and coupled to said nut;a drive adapted to displace said nut within said shaft, anda sensing means, wherein said sensing means is adapted to affect a signal sent via wireless means towards said drive. 2. The rod-less cylinder device of claim 1, wherein said device is adapted to selectably lower from and lift appliances into storage compartments thereby enabling to implement an overhead kitchen system. 3. The rod-less cylinder device of claim 1, wherein said wireless means is optic means. 4. The rod-less cylinder device of claim 3, wherein said optic means comprises a light source and a light detector, and wherein said sensing means determines whether light emitted by said source is detected by said detector. 5. The rod-less cylinder device of claim 4, wherein said optic means comprises a reflector adapted to reflect light received from said source along a path towards said detector, and wherein said sensing means is adapted to bias said reflector and thereby deflect the light away from said detector. 6. The rod-less cylinder device of claim 5, wherein said sensing means is associated with an object being biased by said nut, said object being adapted to slightly move in relation to said nut when abutting an obstacle, wherein said slight movement urges said sensing means to bias the reflector. 7. The rod-less cylinder device of claim 4, wherein said optic means comprises a reflector mounted to said sensing means, and wherein at least at one position of said sensing means said light from said source is reflected along a path towards said detector. 8. The rod-less cylinder device of claim 4, wherein said optic means comprises a reflector adapted to reflect light received from said source along a path towards said detector, and wherein at least at one position of said device said sensing means blocks light being emitted from said source or being reflected towards said detector. 9. The rod-less cylinder device of claim 8, wherein said sensing means is associated with an object being biased by said nut, said object being adapted to slightly move in relation to said nut when abutting an obstacle, wherein said slight movement urges the sensing means to block said light being emitted from said source or being reflected towards said detector. 10. The rod-less cylinder device of claim 8, wherein said sensing means is a plate. 11. The rod-less cylinder device of claim 10, wherein said plate is coupled to said nut. 12. The rod-less cylinder device of claim 5, wherein said reflector is a retro reflector. 13. The rod-less cylinder device of claim 1, wherein said device comprises a lead screw adapted to move said nut along said shaft. 14. The rod-less cylinder device of claim 13, wherein said sensing means is adapted to sense the movement of said nut according to the rate of rotation of said lead screw. 15. The rod-less cylinder device of claim 14, wherein said sensing means comprises a magnet. 16. The rod-less cylinder device of claim 15, wherein each time said magnet rotates a predefined angle a signal is sent to said sensing means. 17. The rod-less cylinder device of claim 16, wherein at given time intervals said sensing means determines movement rate of said nut according to the rate of signals received. 18. The rod-less cylinder device of claim 17, wherein a deviation in movement rate between subsequent time intervals being above a predetermined threshold stops said drive. 19. The rod-less cylinder device of claim 1, wherein said sensing means stops the movement of said nut. 20. The rod-less cylinder device of claim 17, wherein the movement is stopped if an object being biased by said nut reaches an end of the shaft or abuts an obstacle. 21. The rod-less cylinder device of claim 1, wherein said cylinder is configured to displace a same load, wherein said device controls the movement provided by each cylinder to be similar. 22. A rod-less cylinder device adapted to longitudinally displace loads, said device comprising: a shaft;a lead screw adjusted along the longitudinal axis of said shaft, said lead screw being adapted to receive a nut, wherein said nut is confined to move longitudinally within the shaft;a bearing cage adapted to accommodate bearing elements, wherein said bearing cage circumscribes said shaft and wherein said bearing cage is mechanically coupled to said nut;a slider circumscribing said bearing cage, wherein said slider is mechanically coupled to said nut;a drive adapted to selectably rotate said screw, wherein the direction of longitudinal displacement of said nut within said shaft depends on the direction of rotational movement of said drive. 23. The rod-less cylinder device of claim 22, wherein said device is adapted to selectably lower from and lift appliances into storage compartments thereby enabling to implement an overhead kitchen system. 24. The rod-less cylinder according to claim 22, comprising a formwork coupled to said slider and being adapted to slightly move in relation to said slider when abutting an obstacle. 25. The rod-less cylinder according to claim 24, wherein said slight movement of said formwork affects a safety mechanism that stops the drive.
