An antenna device includes: a ground electrode; a first dielectric layer which is provided on one surface of the ground electrode; a feed plate which is provided on a surface of the first dielectric layer opposite from the ground electrode, and which is shorted to the ground electrode; a feed line which feeds to the feed plate; a second dielectric layer which is provided in such a manner as to sandwich the feed plate in combination with the first dielectric layer; and a radiation electrode which is provided on a surface of the second dielectric layer opposite from the feed plate, and which is fed by being electrically connected to the feed plate at a feed point and thereby radiates or receives a radiowave with a first frequency.

Antenna device

A wireless communication apparatus including a first sensor and a second sensor, the apparatus includes: a memory; and a processor coupled to the memory, configured to: input a detection value of the first sensor and a detection value of the second sensor; determine whether or not an object that is located at the wireless communication apparatus exists, based on the detection value of the first sensor; determine a gradient of the wireless communication apparatus, based on the detection value of the second sensor; and regulate transmit power of a radio wave, based on the determination by the first sensor.

Wireless communication apparatus

An input unit inputs input data. A priority determination unit determines priority of the data input by the input unit. A speed control unit sets the communication speed of the wireless communication of the data to be output from an output unit according to the priority of the data determined by the priority determination unit, and also, when input of the data is not detected, sets the communication speed of the wireless communication of the data to be output from the output unit to be lower than the communication speed when the input of the data is detected. The output unit outputs output data by the wireless communication at the set communication speed.

Wireless communication apparatus, information processing apparatus, and wireless communication control method

In a communication apparatus data is inputted to an input section. A priority determination section determines priority of the data inputted by the input section. If the priority of the data determined by the priority determination section is higher than a determined value, then a speed control section sets a transmission speed of the data outputted from an output section to a high value. On the other hand, if the priority of the data determined by the priority determination section is lower than the determined value, then the speed control section sets the transmission speed of the data outputted from the output section to a low value. The output section outputs the data at the set transmission speed.

Communication path speed determining method based on priority of the destination address

An information processing apparatus has a decrypting part configured to receive decrypting key information from a managing apparatus which manages the decrypting key information for decrypting information to decrypt the information; a monitoring part configured to communicate with the managing apparatus, after the decrypting until the information is encrypted again, and a terminating part configured to terminate processing carried out on the information, when the monitoring part cannot receive a predetermined response from the managing apparatus.
