An optically addressed spatial light modulator may be formed with an integrated light emitting device display. The new delivery form in question is a non-aqueous or oily injection formulation, which is obtainable by means of in-situ preparation and subsequent stabilisation of the free, relatively unstable base of the active ingredient. 5 \u03bcm to about 100 \u03bcm with a particle size distribution of no more than 15% of the median particle size, wherein the inorganic material comprises a metal oxide selected from silica, alumina, titania or zirconia. The tear tabs can be configured to break during deployment of the airbag. The actuator is coupled to the manipulandum. In another alternate embodiment of the invention, the current regulator is formed from an RSJ and a serially coupled damping impedance.
