Abstract: An example of an information processing apparatus acquires action data based on an output of a sensor according to a fitness action performed by a player, and executes a game event. In the game event, the information processing apparatus designates at least one type of fitness event from among a plurality of types of fitness events. Each fitness event causes the player to perform a fitness action. During the game event, the information processing apparatus executes a fitness event that causes the player to perform a fitness action corresponding to the designated fitness event until an ending condition is satisfied. The information processing apparatus determines whether or not the achievement condition has been satisfied, based on the action data acquired during the fitness event. The information processing apparatus repeats designation and execution of the fitness event until it is determined that the achievement condition has been satisfied.

Abstract: Provided is an ultrasonic flow sensor with improved practicality. An ultrasonic wave is transmitted and received by an ultrasonic element. A first flow rate value of a fluid in a pipe is calculated based on a propagation time difference of an ultrasonic signal, a measurement value corresponding to an ultrasonic velocity, and a parameter for identifying an inner diameter of the pipe. A second flow rate value of the fluid in the pipe is calculated based on a frequency shift of the ultrasonic signal and the parameter. The first flow rate value is calculated using a propagation time of the ultrasonic signal as the measurement value in accordance with a correspondence relationship among a distance of a path through which the ultrasonic wave propagates through the fluid in the pipe, a time for which the ultrasonic signal propagates in the path, and the ultrasonic velocity.

Abstract: An objective of the present invention is to provide an amplification fiber having a cladding excitation configuration that improves amplification efficiency and an optical amplifier. An amplification fiber (10) according to the present invention is a multi-core amplification fiber having, from one end (E1) to the other end (EE), a plurality of cores (11b) in a cladding (11a), and a total distance from the one end (E1) to the other end (EE) in which rare earth ions are doped differs depending on the types of cores (11b). The cores (11b) are preferably disposed such that the cores of the same type are not adjacent to each other. By arranging the types of the cores in this manner, requirements for inter-core crosstalk can be mitigated since the bands of signal light in the adjacent cores are different. As a result, a density of cladding excitation light can be increased by shortening the inter-core distance, and thus the amplification efficiency can be improved.
