  • Publication number: 20090068404
    Abstract: The invention concerns a decorative casing fabricated by bonding a film having a polarizing characteristic to the surface of the casing body via an adhesive layer, and an object of the invention is to provide the casing with enhanced decorativeness by designing the adhesive layer so as to render various color effects in addition to the effect rendered by the polarizing characteristic. The polarizing film is bonded to the surface of the casing body via the adhesive layer containing a special-effect material having a color effect. According to the present invention, by directly bonding the polarizing film to the casing via the adhesive layer that produces a desired color effect, other effects such as color hue can be conferred in the film bonding step, and thus a casing having an excellent decorative effect can be manufactured by a simple process without increasing the number of process steps.

  • Publication number: 20090005699
    Abstract: An input system executes an input to an information processing apparatus depending on the hand motion of a person. At least one myoelectric sensor is provided on an area between a wrist of the person and bases of a second finger to a fifth finger, and detects a myoelectric signal depending on the hand motion. A standard value obtaining portion outputs a command to make the person maintain a hand in a constant posture in a state where the myoelectric sensors is worn on the hand, and obtains a value based on the myoelectric signal detected by the myoelectric sensor after the output of the command, as a standard value. A calibration portion calibrates a myoelectric signal depending on the hand motion after the standard value is obtained by the standard value obtaining portion, with the standard value.
