Abstract: An information processing apparatus includes: a storage that stores first detection object information; and a processor that acquires second detection object information, in which the processor determines whether an undetected object that has not been detected in the first parking is present, based on the first detection object information and the second detection object information, and changes an aspect of the notification when the undetected object is present.

Abstract: A preparation process of block copolymers which comprises conducting living polymerization of a (meth)acrylic ester substantially in the absence of water, by using a macromolecular compound having a functional end group represented by the formula (1): ##STR1## Wherein R is H or an n-alkyl group having from 1 to 3 carbon atoms and R' is H or an alkyl group having from 1 to 6 carbon atoms, as a polymerization initiator and in the presence of a Lewis acid or in the presence of a donor compound of an anion selected from HF.sub.2.sup.-, (CH.sub.3).sub.3 SiF.sub.2.sup.- or F.sup.-, as well as novel block copolymers prepared therefrom are disclosed.

Abstract: The present invention provides shaped articles having good transparency and high oxygen permeability in a specific direction thereof, which have been made from a block copolymer (a) composed of a polyalkyl methacrylate segment and a silicone-based polymethacrylate segment, or a block copolymer (b) or graft copolymer (c) containing a polyorganosiloxane as one component, according to a process permitting the creation of a specific higher-order structure. These shaped articles have high oxygen permeability at relatively low silicone contents and, therefore, can provide oxygen-permeable products having high tear strength and surface hardness.

Abstract: An antistatic agent capable of imparting a permanent antistatic property to a methacrylic resin is prepared as follows. First, an alkyl methacrylate is subjected to living polymerization in an atmosphere substantially free of water in the pressure of at least one compound acting as a source for supplying an anion selected from HF.sub.2.sup.-, (CH.sub.3).sub.3 SiF.sub.2.sup.- and F.sup.- by using as an initiator a compound represented by the formula (I) or (II): ##STR1## wherein R is H or CH.sub.3 and R.sup.1 is H or alkyl; second, a methacrylic acid ester comprising at least 80 mole % of a methacrylic acid ester represented by the formula (III): ##STR2## wherein R.sup.2 is alkyl and m is from 1 to 6, is subjected to living polymerization in the presence of the polymer obtained in the first step, to prepare a di-block or tri-block copolymer; and then, amino groups of segments derived from the methacrylic acid ester of the formula (III) in the block copolymer are quaternized.
