    摘要： The present invention relates to lenses that are capable of post-fabrication power modifications. In general, the inventive lenses comprise (i) a first polymer matrix and (ii) a refraction modulating composition that is capable of stimulus-induced polymerization dispersed therein. When at least a portion of the lens is exposed to an appropriate stimulus, the refraction modulating composition forms a second polymer matrix. The amount and location of the second polymer matrix may modify a lens characteristic such as lens power by changing its refractive index and/or by altering its shape. The inventive lenses have a number of applications in the electronics and medical fields as data storage means and as medical lenses, particularly intraocular lenses, respectively.

    摘要： This invention relates to a steerable articulation coupler for effecting rapid connection of the two sections of a ground vehicle. The coupler also provides for rapid automatic connection of the power transmission shaft. The coupler consists of a socket member and an insertion member. The insertion member includes a forward semi-spherical support surface, a rearward large diameter support surface, a guide receptacle and a set of alignment members. Counterparts on the socket member cooperate with the insertion member to align the two members.
