A multidirectional input device includes ring-shaped resistance element layer 18, first conductive layer 22 and second conductive layer 23 shaping in arcs corresponding to resistance element layer 18, and knob 14 having ring-shaped protruded section 14D. Frequency or Time-frequency correlation-based scheme, with exploitation of time-frequency correlation characteristics of the pilots, may be used for identifying the positions of the pilots in frequency or time and frequency dimensions consisting of received symbols. The sampling module includes a second sampling unit and a third sampling unit. A sealing member is fitted into the closure cap to close the dispensing opening in the reservoir. The arms are restored to their normal orientation once the impact shock dissipates. The sensor is secured to a wheel rim whereby prolonged exposure to liquid tire fill material is avoided, even when the wheel is oriented with the sensor at a lower-most location of the wheel rim.
