A buckle assembly for a vehicle restraint system where the buckle assembly is adapted to receive a plurality of belt connectors, with the belt connectors being simultaneously released upon moving at least one handle to a release position. Therefore, convenience in the use of web services may increase. The realization of the combined filters is accomplished by transforming the pair of filters into a single \u201ccombined\u201d polyphase filter with coefficients that are time variant in a specific manner. The other selected flank is made up of three facets and four radii, giving it irregular features forming a complex geometric profiles. A distinctive ring signal is then generated corresponding to the identified callee of the incoming telephone call. Moreover, according to the present invention, it is possible to cause a motor to be operated with an ideal track and, since it is possible to always monitor a present position, it is made easy to cause a plurality of axes to be synchronously operated.
