An impact sensing device including a plurality of accelerometers orthogonally oriented with respect to each other and attachable at a body location, each capable of producing a signal indicative of an impact. In one example, a triggering region is designated. The application transfers at least the position of the memory area, an identifier for specifying a parameter, and the setting value of the parameter to the printer driver or function extension module to set the setting value in the parameter specified by the identifier of the memory area. A low-adhesion energy surface with a water contact angle of at least 90 degrees is provided on an inner surface of the primary liquid chamber. Since the external indicators are kept off during picking up the image, the sight line of a person to be authenticated does not move to the external indicators thus picking up an iris image without blurs. These contain a resin part for transmitting black colorant and a resin part for absorbing black colorant.
