Abstract: A control method includes: converting a first write command received from a host to a second write command for each SSD belonging to an active pool, holding, with respect to the SSD, an end address of data written in the immediately prior second write command, and holding a discontinuity count, which is the number of times the end address and the write address for the newest second write command are discontinuous; and when the discontinuity count for a first SSD among the SSDs belonging to the active pool exceeds an upper limit value, copying a plurality of data, for all of the data held by the first SSD, to a region to which the write address is continuous in a second SSD that belongs to a standby pool and is initialized, deleting the first SSD from the active pool, and adding the second SSD to the active pool.

Abstract: In order to implement an external antenna of a radio device with a simple configuration, an antenna according to the present invention includes: a conductor plate; a first linear conductor including a portion disposed substantially in parallel to an edge of the conductor plate, and being curved halfway and connected to the conductor plate with a gap being interposed; a second linear conductor intersecting with a line extending from an end of the first linear conductor opposite to a connection end thereof connected to the conductor plate, and being connected to the conductor plate; a third linear conductor being connected to an end of the second linear conductor opposite to an end thereof connected to the conductor plate, and being disposed substantially in parallel to the first linear conductor; and a fourth linear conductor being disposed in a direction apart from the conductor plate at an end of the third linear conductor opposite to an end thereof connected to the second linear conductor.

Abstract: The wearable antenna device includes an antenna part—attached to a part of a garment including a body accommodation part—that accommodates a part of a body, and a functional element arranged in a position of the garment in such a way that at least a part of the functional element is opposed to the antenna part with the body accommodation part interposed therebetween.

Abstract: To display an image even on a projection surface having complex unevenness similarly to a flat, a projection device includes: a storage unit storing at least a pattern image for detecting distortion depending on a state of the surface, an expected image associated with a displayed image of the pattern image displayed on a flat, and a desired projection image; a projection unit projecting an image including the pattern image and the desired projection image; an image acquisition unit acquiring a displayed image of the pattern image, and extracting a distortion image; a distortion amount calculating unit calculating a distortion parameter for distortion by comparing the expected image with the distortion image; a distortion correction processing unit correcting the projected desired projection image by using the distortion parameter; and an image output unit outputting, to the projection unit, image data including the corrected desired projection image and the pattern image.

Abstract: A wireless communication apparatus (1) includes an information acquisition unit (10) for acquiring information about a wireless terminal when the wireless terminal is wirelessly connected to the wireless communication apparatus, a storage unit (11) for storing the information about an authorized terminal acquired by the information acquisition unit (10) in association with an individual identifier of the authorized wireless terminal, and an evaluation unit (12) for evaluating as to whether or not the wireless terminal wirelessly connected to the wireless communication apparatus is an authorized wireless terminal. The information includes at least fixed information other than the individual identifier. The evaluation unit (12) makes the evaluation based on a degree of matching between the information about the wireless terminal to be evaluated acquired by the information acquisition unit (10) and the information stored in the storage unit (11).

Abstract: A pill case (100) includes a pocket (9) which receives one pill (10) from an accommodation unit (8) in which a plurality of pills (10) are accommodated, and an extraction port (11) for ejecting the pill (10) in the pocket (9) to the outside. The pill case (100) includes a manipulation unit (for example, pill ejection button (4) and pill tray (5)) which converts a state in which the pill (10) in the pocket (9) cannot be ejected through the extraction port (11) to a state in which the pill (10) in the pocket (9) can be ejected through the extraction port (11) by being manipulated by a user. The pill case (100) includes a moving unit which is moved by indirectly or directly receiving a pressure from the pill (10) in the pocket (9) according to the moving manipulation to the manipulation unit, and a detection unit which detects that the moving unit is moved up to a position of the moving unit which corresponds to a state in which the pill (10) in the pocket (9) can be ejected.

Abstract: A difference management apparatus includes: a first difference management table which manages first difference map information; and a second difference management table in which, when an area-wide difference(s) has not occurred in a first management unit of the first difference management table, an entry(ies) for managing second difference map information associated with the first difference map information in the first difference management table is generated, the second difference map information indicating a location(s) of occurrence of a difference(s) in the first difference map information in a second management unit finer than the first management unit.
