摘要:
A content display apparatus which processes protected information configured, with an aim to prevent access from any unauthorized program, to include: a process managing unit which manages a plurality of processes operable in the content display apparatus; and an access detecting unit configured to detect access to the protected-information access detecting unit which detects access to the protected information. The process managing unit includes an application execution control unit which temporarily stops the operation of each of at least one process other than a process which accesses the protected information among the plurality of processes when the access to the protected information is detected by the protected-information access detecting unit.

A gaseous constituent supply device for supplying an air vortex ring containing a gaseous constituent includes a first chamber for holding the gaseous constituent, a compressing portion for compressing air in the first chamber, and a second chamber communicating with the first chamber through an opening. The second chamber holds the gaseous constituent therein. The air vortex ring is generated in the second chamber such that air blown from the first chamber into the second chamber through the opening takes in the gaseous constituent in the second chamber. The second chamber has an emitting outlet, through which the generated air vortex ring is emitted, and the emitting outlet is provided opposite to the opening.

An authenticator apparatus which makes it difficult for an unauthorized user to masquerade and enhances safety includes an authenticating information holding unit (102) previously stores characteristic information indicating an input and output characteristic involving an environment change of an authentic authenticatee apparatus entitled to be authentic, an authenticating information transmitting unit (107) which transmits authenticating information to a portable medium (2), a response information receiving unit (108) which receives response information outputted from the portable medium (2) in response to an input of the authenticating information, an environment selecting unit (105) which identifies an environment of the portable medium (2), and a response information confirming unit (109) which determines whether or not the authenticating information and the response information satisfy the input and output characteristic indicated in the characteristic information stored in the authenticating information holding unit (102), and judges that the portable medium (2) is authentic in the case where the input and output characteristic is satisfied, the authenticating information and the response information being in the environment identified by said environment identifying unit.
摘要:
A device (110) according to an implementation of the present invention, having a plurality of virtual machines (1002, 1003, 1004, and 1005), includes a virtualization software (1001) which manages the virtual machines. The virtualization software includes an application VM creating unit (1300) which creates a virtual machine for executing a program. A first virtual machine (1002) determines whether a first program is to be executed on the first virtual machine or to be executed on a virtual machine other than the first virtual machine. When the first virtual machine determines that the first program is to be executed on the other virtual machine, the application VM creating unit creates a second virtual machine for executing the first program.
摘要:
A vehicle air conditioner includes a cooling heat exchanger arranged in a casing, a compressor control portion which controls a compressor such that a cooling temperature at the cooling heat exchanger approaches a target cooling temperature, and a dryness determination portion which determines whether an outer surface of the cooing heat exchanger is dry or not based on a humidity in the casing. A target temperature determination portion determines the target cooling temperature to be any one of target temperatures including a first target temperature that is lower than a dew-point temperature in the casing, when the dryness determination portion determines that the cooling heat exchanger is not dry. The target temperature determination portion determines the target cooling temperature to be any one of the target temperatures other than the first target temperature, when the dryness determination portion determines that the cooling heat exchanger is dry.
摘要:
The sunlight collection system is provided with a reflecting mirror which is placed on the surface of the ground to reflect sunlight, a light receiving means which is disposed above the surface of the ground and has an incident portion into which the sunlight reflected by the reflecting mirror is made incident, light amount sensors which are mounted at least at two locations facing each other at an outer edge of the incident portion of the light receiving means, a turning mechanism which allows the reflecting mirror to turn around at least one axis, and a direction control unit which obtains light amounts detected respectively by the light amount sensors that face each other, while allowing the reflecting mirror to turn by driving the turning mechanism, thereby adjusting an angle of the reflecting mirror on the basis of the light amounts.
摘要:
In the key management software having a key database with a tree structure, a high-speed data encryption/decryption process is achieved by changing the tree structure without reducing the security strength when deleting or adding a key from/to the tree structure. The key management software having the key database with the tree structure, when deleting or adding a key from/to the tree structure, refers to the encryption strength comparison table and the process time comparison table to change the tree structure without reducing the security strength. This reduces the number of times an encrypted key is loaded onto the encryption/decryption processing device during the data encryption/decryption process, thus achieving a high-speed data encryption/decryption.
