  • Patent number: 6847885
    Abstract: An information providing center calculates an estimated traveling time to elapse before a vehicle arrives at a destination by using traveling information transmitted from an on-vehicle system and determines contents information to be provided to the on-vehicle system in conformance to the calculated traveling time. The information providing center prepares a program list containing the contents information that has been selected, information indicating the order in which the contents information is to be played and media information indicating how the contents information is to be obtained and transmits the program list to the on-vehicle system. The on-vehicle system obtains and plays the contents information as indicated in the transmitted program list.

  • Patent number: 6835906
    Abstract: A plating layer (or vapor deposition layer) which exhibits a metallic color is formed on the surface of a molded resin part. A color film with transmittance which is molded and which has a desired color for design is formed on the surface of the above plating layer (or vapor deposition layer). This color film comprises moldable materials such as resin including, for example, polymer compounds such as PET, PC, urethane or combinations of these. Thereby, a press button switch can be gained which imparts a feeling of high quality through a metallic finish design, of which the degree of design freedom is high and which can prevent color unevenness of the key top from occurring.
