Abstract: An electronic device includes: a communication device configured to communicate with a server device that provides data; a storage device; and a control device that cyclically accesses the server device using the communication device to check whether or not new data has been provided from the server device, determines, based on a predetermined probability, whether to download the new data from the server device or to postpone download when the new data has been provided, and stores, in the storage device, the new data downloaded from the server device.

Abstract: A reservation support method includes: acquiring a progress status of reading by a user for a book; specifying a recommended reservation time of a facility based on the progress status; presenting the specified recommended reservation time to the user; and accepting a reservation.

Abstract: A replacement support apparatus is provided for supporting replacement of a plurality of electronic apparatuses each including a plurality of device components. The replacement support apparatus is provided with: a communication circuit, a storage, a processing circuit, and an output device. The communication circuit receives, from a plurality of existing electronic apparatuses, operation information indicating operation conditions of the device components during operation of the existing electronic apparatuses. The storage stores specifications information indicating specifications of new electronic apparatuses as replacement candidates.

Abstract: A projection device is provided, which is capable of suppressing or preventing problems that result from a light emission delay of a light source. The projection device includes a plurality of light sources respectively emitting a laser light; a scanning part enabling the laser light to scan; and a controller controlling an output of the laser light. In a scanning range including a first scanning range and a second scanning range, the controller controls such that the output has a first light amount in the first scanning range and has a second light amount which is greater than the first light amount in the second scanning range.

Abstract: A portable communication device which is improved in operationality for taking pictures of a landscape and the like by its camera, and ensures excellent portability. The portable communication device comprises: a main body which has an operation section including operation keys and buttons on its main surface; a cover which has a display section for showing information, and is foldably joined to the main body; and a camera having an objective lens. The cover includes a rotation supporting section which is supported for rotational movement relative to the main body on a first axis, and a display section which is supported for rotational movement relative to the rotation supporting section on a second axis running at right angles to the first axis. The rotation supporting section is provided with the objective lens in a position facing the operation section on the main body when the portable communication device is folded up.

Abstract: The present invention relates to an eddy current testing probe, which is suitable for used in a nondestructive test. The eddy current testing probe is provided with an excitation coil (2, 2a, 2b) which generates an alternating magnetic field to generate an eddy current (12) in a specimen (10), and a pair of detection coils (1a, 1b) differentially connected and arranged in phase. A central portion (C1) of the pair of detection coils and a central portion (C2) of the excitation coil (2, 2a, 2b) are arranged to be located at an identical or an almost identical position in a plan view taken in the direction toward the specimen (10), and a flaw (11) on the specimen (10) is detected based on a difference between voltages generated in the pair of detection coils (1a, 1b) due to the eddy current (12).

Abstract: A signal processing apparatus includes a 2-dimensional conversion processing section, a 2-dimensional emphasis and attenuation processing section and a 2-dimensional smoothing processing section. The 2-dimensional conversion processing section maps an observation signal in a first coordinate system onto a second coordinate system to output a 2-dimensional converted signal. The observation signal includes a detection object component and a noise component to be attenuated. The noise component is composed of a first noise component and a second noise component. The 2-dimensional emphasis and attenuation processing section attenuates the first noise component to emphasize the detection object component and outputs a 2-dimensional filtered signal in which the detection object component is emphasized.
