Abstract: [Object] To propose an information processing device, wireless communication system, information processing method, and storage medium which can mutually authenticate communication partners simply and safely. [Solution] The information processing device including: an acquisition unit configured to acquire first identification information for identifying another terminal; and a communication unit configured to transmit information for mutual authentication between an own terminal and the other terminal to the other terminal specified based on the first identification information through a network service.

Abstract: A head-mounted display, a smart phone, a tablet terminal, an electronic book, or the like monitors conditions of the side of a power generation apparatus that charges a battery. An image display apparatus includes a power generation information acquisition means for obtaining power generation information on a power storage amount, a power generation amount, and the like of a secondary battery in each power generation apparatus, appropriately processes the obtained information, and displays it to a user via a display unit. The user can check the power generation amount of the power generation apparatus and the power storage amount of the secondary battery without stopping the use of the image display apparatus. When a power storage amount of a battery in use is lowered, the user can properly judge with which of the power generation apparatuses the user should replace the battery.

Abstract: There is provided a wireless communication apparatus including: a communication unit configured to use wireless communication to transmit and receive data related to a service provided by at least one of the wireless communication apparatus and another wireless communication apparatus with other wireless communication apparatuses present within a designated range; and a control unit configured to associate service information for identifying the service with user information for identifying a user using a wireless communication apparatus that provides the service, and include and transmit the associated information in the data.

Abstract: There is provided a semiconductor integrated circuit, including a test circuit, a plurality of signal cells, a power supply cell, and a control circuit. The test circuit performs a predetermined test on a test target circuit. A plurality of signal cells input an input signal into the test circuit and the test target circuit. The power supply cell supplies power to some of the plurality of signal cells in the test. The control circuit controls a value of the input signal from signal cells that include signal cells to which the power is not supplied and that are not used in the test, to be a predetermined value.

Abstract: An ultrasonographic system includes an electronic memory to store a table that relates subject information to a plurality of frequencies, and a frequency setting unit that sets the examination frequency to one of the frequencies stored in the table. The frequency setting unit sets the examination frequency based on selection of subject information from the table, and the examination frequency is used to perform ultrasound examination on the subject according to the selected information.

Abstract: The present technology relates to information processing apparatus and method, and a program, which are capable of presenting an operation input unit in a position in which a user easily performs an input operation. An imaging unit captures an image of a vicinity of a display unit. A hand recognition unit recognizes a hand by extracting a hand image obtained by capturing a hand, based on feature information of the hand, from the image captured by the imaging unit. The hand position detection unit specifies a real position on a display unit from information on a position in an image in which the hand image is present. A display control unit for an operation input unit displays an operation input unit in a position on the display unit which is specified based on the position of the hand detected by the hand position detection unit.

Abstract: A head- or face-mounted image display device includes an environmental information acquisition unit that acquires environmental information, a state information acquisition unit that acquires state information, a guidance information generation unit that generates guidance information for guidance into a state in which the influence of environment is reduced or increased based on at least one piece of environmental information acquired for each state, and a provision unit that provides the guidance information.

Abstract: There is provided a communication apparatus including a communication unit having an optical communication scheme and a different communication scheme from the optical communication scheme, a level setting unit configured to set a security level in data communication, and a communication scheme switching unit configured to switch communication schemes of the communication unit in accordance with the security level that is set by the level setting unit.

Abstract: There is provided a pacemaker apparatus including a course setting unit configured to set a movement course along which a user moves, a lap time data acquisition unit configured to acquire data of one or more lap times of one or more persons during movement along the course set by the course setting unit, and a target lap time generation unit configured to designate a lap time of a person selected by the user among the data of the one or more lap times of the one or more persons acquired by the lap time data acquisition unit as a reference lap time and generate a target lap time based on data of the reference lap time.

Abstract: Provided is an environment control apparatus including an input unit into which information from a medical device is input, and an environment control unit configured to control an environment perceived by a subject based on the information input into the input unit.

Abstract: An optical printing head for an optical printing device includes a long board with aligned light emitting diode arrays having a plurality of light emitting areas mounted and fixed on the board thereof, a holder provided with a staged portion therein, a fixing by pressure means for fixing the board to the staged portion of the holder by pressure and a lens array held at a predetermined position with respect to the board by the holder. This arrangement allows an optical printing head to be made small in scale and easy to be assembled without deteriorating printing quality.
