Abstract: An electronic apparatus allows communication devices to be connected thereto, and has a plug-and-play function of automatically setting a communication device to be connected. A communication monitoring module monitors the communication statuses of the communication devices connected to the electronic apparatus. A registry stores information indicative of the priorities in use of the communication devices connected to the electronic apparatus. A switching module uses a plug-and-play function to switches the communication devices such that one communication device is used exclusively, on the basis of the communication statuses of the communication devices obtained from the communication monitoring module and the information stored in the registry.

Abstract: According to one embodiment, an information processing apparatus includes a display device, a wireless networking adapter including a function of making an inquiry whether an e-mail transmitted to a predetermined address is newly received to a mail server, and a notification unit configured to notify a newly received e-mail via the display device when the wireless networking adapter detects a newly received e-mail.

Abstract: According to one embodiment, an information processing apparatus, includes a communication unit making communication with a mail server and obtaining a mail, a searching unit discriminating whether or not a new mail has arrived at the mail server, a main controller controlling the communication unit and the searching unit, and obtaining a new mail, a main power supplier supplying power to the main controller, and a sub-controller. The sub-controller discriminates whether or not a new mail has arrived on the predetermined timing by the searching unit during suspension of the main controller, obtains the new mail via the communication unit if the new mail has arrived, and urges the main power supplier to supply the power and sets the main power supplier in an operable state if any item of information included in the new mail meets a predetermined condition.

Abstract: According to one embodiment, an information processing aparatus including a function of performing dial-up access to a server computer through a radio base station forming a radio service area in a predetermined geographic area, includes a monitoring unit configured to monitor whether or not the processing aparatus is placed in a radio service area to which the processing aparatus belongs when dial-up access is performed successfully, and an automatic log-off unit configured to forcibly terminate use of the processing aparatus when the monitoring unit detects that the processing aparatus departs from the service area.

Abstract: A network access control method comprises setting certificate information for each of user terminals, the certificate information including a user identification and access right information indicating a limited access right to a network, determining whether the user terminal is authenticated based on a user identification, and controlling access to the network in accordance with the certificate information when the user terminal is authenticated.

Abstract: An electronic apparatus performs wireless communication selectively using one of a first wireless communication device for performing wireless communication by a first wireless communication system and second wireless communication device for performing wireless communication by a second wireless communication system. The electronic apparatus includes a unit for storing base station information relating to a position of a base station corresponding to a first wireless communication system and a position of a base station corresponding to a second wireless communication system, a unit for detecting a current position of the electronic apparatus, and a unit for switching between the first wireless communication device and the second wireless communication device based on the detected current position of the electronic apparatus and the base station information.

Abstract: This invention provides an information device which disenables unselected wireless devices by directly controlling hardware, and thus can prevent interference between wireless devices using the same frequency band. In this invention, a BIOS controls an EC for a wireless module selected based on a user instruction, thereby controlling power supply to a Bluetooth module and power supply to a wireless LAN module. This makes it possible to enable either one of the modules and disenable the other module.

Abstract: A control system which is capable of selectively using any of a plurality of communication devices. When an operator selects a desired communication device from a plurality of communication devices, state information concerning each of the communication devices is rewritten so as to render only the selected communication device usable. The control system uses properties of the OS to temporarily stop all the communication devices, and thereafter controls only the selected communication device usable in accordance with the changed state information.

Abstract: An atmospheric pressure, elevated temperature gas desorption apparatus which enables quanitiative analysis of impurities absorbed in or on the surface of a solid sample (semiconductor wafer, optical disc, etc.) is disclosed. The atmospheric pressure, elevated temperature gas desorption apparatus for desorbing impurities absorbed in or on the surface of a plate-like solid sample 18 into a carrier gas 19 in a chamber 6 under an atmospheric pressure while increasing the temperature of the solid sample 18 includes a desorption room 7A provided in the chamber 6 and connected through to a first gas supply system 1 for supplying the carrier gas 19, for desorbing impurities absorbed in or on the surface of the solid sample 18 into the carrier gas 19. A sample support room 7B is provided in the chamber 6 and is separated from the desorption room 7A by a partition member 6A. The solid sample 18 is in close contact with the partition member 6A.

Abstract: An X-ray tomography scanner and an optical tomography scanner are combined to obtain an optical image indicting metabolism in the body. Optical projection data indicating light pulse transmissions in the body are compensated by using a light scattering coefficient distribution determined by an X-ray tomogram image discriminated into individual internal organs or tissues. The compensated projection are back-projected.

Abstract: A rotating drum for use in a magnetic recording system. A magnetic head is mounted on the rotating drum, and a magnetic recording medium is wound on the rotating drum, and the rotating drum is rotated so as to read and write signals. Alternatively, the magnetic recording medium is mounted on the rotating drum, and signals are read and written by a magnetic head fixed exteriorly of the rotating drum. The rotating drum has at least one opening or notch in a magnetic recording medium-winding surface thereof. In order to restrain the deformation of the rotating drum during the rotation thereof, the center of gravity of the drum is disposed substantially in registry with the axis of rotation of the drum.
