A method and device for filtering an input signal received by an input module in order to produce a filtered input signal, wherein the received input signal is converted such that it has either a HIGH input state or a LOW input state each having a time duration characteristic of the input module, and the filtered input signal is represented by an ON filtered state and an OFF filtered state. By working with smaller blocks, the image processing may begin before an entire image is scanned or before the entire image is loaded into a memory or buffer. The valve rod has a plurality of fluid passages spaced longitudinally along the valve rod, and the valve rod is movable to align each fluid passage with an inlet or outlet port in the first chamber to allow fluid to flow through selected inlet or outlet ports corresponding to selected fluid passages. The input data includes the speed and acceleration of the vehicle, whether the vehicle’s brakes are being applied, collision warning sensitivity, driver distraction modifiers, road condition data, such as wiper speed and outside air temperature, etc. In accordance with the invention, the locking means are declutchable, so as to enable the end-piece to be dismounted from the front end of the spine member. These parameters may allow a network operator to guide M2M application behaviour in accordance with potentially limited recourses in the network.
