Abstract: A non-secure network gateway 11 and a secure network gateway 12 are realized by mutually independent computers, and are connected, by standard protocol communication portions 20 and 25, to a non-secure network 1 and a secure network 2 using a standard protocol the standardized specifications of which have been published. Data exchange between nonstandard protocol communication portions 22 and 23 of the sub-gateways 11 and 12 is performed using a nonstandard protocol the specifications of which have not been published, and data exchange between the nonstandard side and the standard side is performed only in the application layer. Protocol conversion portions 21 and 24 refers to relay permission settings tables 30 and 31 to confirm relay permission for communication data, and perform protocol conversion only when relaying is permitted. Even in the event that illicit communication data from one network has penetrated into a gateway, penetration of the communication data into the other network can be prevented.

Abstract: A judgment unit judges the pass/fail of DUTs. A power supply circuit has changeable characteristics, and supplies a power supply signal to the DUTs. A condition setting unit performs a pilot test before a main test for the DUTs, and acquires a test condition to be used in the main test. The condition setting unit executes: (a) measuring a first device characteristic value for each of multiple pilot samples sampled from among the DUTs while emulating a power supply characteristic close to what is used in a user environment in which the DUT is actually used; (b) measuring a predetermined second device characteristic value for each of the multiple pilot sample devices while emulating a power supply characteristic close to what is used in a tester environment in which the main test is performed; and (c) determining the test condition based on the first and second device characteristic values.

Abstract: An object is separately located from a touch panel in a touch panel coordinate system, and visible by a user via the touch panel. A touch position detector detects the user's touch position on the touch panel. The user's touch position is converted to a touch position in a world coordinate system using a position information of the touch position detector in the world coordinate system. A half-line connecting the touch position and a view position of the user is generated in the world coordinate system. It is decided whether the half-line crosses the object using a position information of the object in the world coordinate system.
