摘要:
A mobile terminal, and an information providing method and system which immediately provides information, which the user of the mobile terminal desires, for the mobile terminal. Area and related service information are stored in corresponding relationship in a database. An information server which includes means for calculating the area of the destination of the mobile terminal loads information on the destination area from the database to the mobile terminal which moves toward the destination area, using radio communication means before the mobile terminal arrives at the destination area.

Data is compressed/encrypted for communication between application programs without addition of any modification to the application programs. In a communication system where a plurality of personal computers are connected to each other using communication lines, a personal computer is provided with a communication program and an application program, the application program uses a command offered by the communication program for transmission and reception of data with another personal computer, a hooking program for discriminating the command related to the data communication issued by the application program is provided and, after the hooking program has compressed or encrypted the data of application program depending on a type of the command, the command is transferred to the communication program.

A radio LAN system based on a frequency hopping control scheme in which a deviation between frequency hopping timing in a cell and frequency hopping timing in another cell is measured, and as the deviation increases close to such a degree that causes interference, a frequency hopping pattern currently used in the cell is replaced with another frequency hopping pattern, or the order on the frequency hopping pattern is changed to avoid interference between the cells.

Disclosed herein is a computer system which comprises a plurality of input/output devices, an adapter device coupled to the plurality of input/output devices and a main processing unit for supplying an input/output request to each of the plurality of input/output devices through the adapter device. A plurality of input/output commands are respectively issued to the plurality of input/output devices from the main processing unit as one input/output start command. The adapter device specifies to which input/output devices the plurality of input/output commands included in the one input/output start command correspond. Further, the adapter device supplies input/output commands to the specified input/output devices respectively.

A diffusion sheet includes a light-transmissive base member, a plurality of structures, and a flattened portion. The light-transmissive base member has a first main surface and a second main surface. The plurality of structures have convex shapes, which are randomly formed on the first main surface. The flattened portion is formed among the plurality of structures on the first main surface and has a surface roughness (Ra) equal to or lower than 0.6 μm.

摘要:
In a method of diagnosing deterioration of a paint film, a probe is applied to the surface of a paint film. A voltage having a predetermined waveform is applied by a preamplifier across the probe and a base metal on which the paint film is formed. A current flowing through the paint film is measured by the preamplifier. An analog signal indicative of a measured current value is converted to a corresponding digital signal by an analog-to-digital converter. A personal computer operates to analyze the digital signal in accordance with a predetermined analyzing procedure so that the degree of deterioration of the paint film is determined. The resultant determination is displayed on the display.
