A power supply system is mounted in the capsule device, comprises an electrode pair including at least two electrodes provide on an outer wall surface of a capsule main body, for example, an aluminum electrode and a catalyst-supporting carbon electrode, generates power when immersed in an electrolytic solution consisting of gastric juice or intestinal juice, and supplies the power to constituent portions in the capsule device.

Abstract: In a non-reading mode, a bar code is detected by irradiating it with a laser beam from a laser source, power consumption of which is reduced, and it is determined whether or not the detected bar code is correct. The mode is changed from the non-reading mode to a reading mode in which the laser source operates at substantially full power if it is determined that the code symbol is correct. The non-reading mode continues if it is determined that the code symbol is not correct. This enables an auto-trigger function that triggers reading of the bar code automatically. Therefore, it is possible to eliminate conventional parts and/or special-purpose circuits for realizing the auto-trigger function so that the optical-information-reading apparatus can be downsized.

Abstract: In the information presentation apparatus of the present invention, it is possible for the user to effectively present information relative to first information. A memory stores first information including at least one part corresponding to second information. The first information is displayed and the user indicates the part corresponding to the second information in the displayed first information. In response to the indication, a summary of the second information is read from a data file and stored in the memory. The summary is displayed in addition to the first information. Therefore, the user can previously know an outline of the second information.

Abstract: A virtual reality data presentation system capable of improving naturalness of the system operation and data presentation.

Abstract: A realistic image display system includes an input section, a storage section, a light source data specifying section, a parameter specifying section, a polygon generating section, an image generating section, and a display section. The polygon generating section generates a set of polygons indicating the effects of a light source on three-dimensional space on the basis of three-dimensional object data including a three-dimensional object, the location of the object in the three-dimensional space, and a three-dimensional object attribute, and parameters specified at the parameter specifying section. The image generating section performs coloring on the three-dimensional object and the set of polygons on the basis of the three-dimensional object data, the light source data, and the parameters, thereby generating a display image.
