Abstract: In an actively controlled automotive suspension system, suspension characteristics are controlled on the basis of rolling and/or pitching energy representing parame­ters. A correction factor (S F ,S R ) representative of self-induced attitude change is derived on the basis of vehicular attitude change velocity (φ̇) for cancelling the self-induced rolling and/or pitching. By cancelling the self-induced rolling and/or pitching creative com­ponent from the rolling and/or pitching acceleration factor, higher rolling and /or pitching response characteristics can be provided so as to obtain satis­factorily high driving stability and riding comfort.

Abstract: A method for forming pads (11) of pressure sensitive adhesive coated sheets with similar discontinuities (e.g., printed indicia (10) or openings (13)) on the sheets substantially aligned. A strip (16) of pressure sensitive adhesive coated material is helically wound around the periphery of a roller (18) to form a roll (20) comprising a multiplicity of overlying layers of the strip (16) by rotating the roller (18) about its axis to pull the strip (16) along a predetermined path (22) onto the roller (18). Discontinuities are formed on the strip (16) along the predetermined path (22) at locations that are progressively increasingly spaced apart to compensate for the increasing circumference of the roll (20) and which result in at least one set of discontinuities being located along the periphery of the roller (18) in substantial alignment radially outwardly of the roller (18); and pads (14) containing such aligned discontinuities are then cut from the roll (20).

Abstract: The detector comprises only a single coil (1) within which a core (2), normally connected to a device whose position is to be determined, moves axially. The core (2) consists of a ferromagnetic rod (4) surrounded by a tube (5) made of a material which has a good electrical conductivity but a low magnetic permeability. An alternating current (I) is supplied to the coil and this produces eddy currents in the tube (5). The reduction in sensitivity due to the increase in the resistivity of the tube (5) as the temperature rises is compensated by an increase in sensitivity due to the increase in the permeability of the rod (4) as the temperature rises. The detector is lightweight and compact and its temperature compensation operates over a range from -40 DEG C to +250 DEG C.
