Abstract: An abnormality detection apparatus (100) is configured to detect an abnormality of a lighting device (200). The abnormality detection apparatus (100) includes an illuminance sensor (110), a memory (120) and a controller (130). The controller (130) is configured to detect the abnormality of the lighting device (200) based on a criterion stored in the memory (120) and a difference between an illuminance detected by the illuminance sensor (110) during on state of the lighting device (200) and an illuminance detected by the illuminance sensor (110) during off state of the lighting device (200).

Abstract: In this azimuth angle sensor, original magnetic detection data is sequentially acquired as data points in a triaxial coordinate system by detecting magnetism on three axes. An offset derivation device provided to the azimuth angle sensor derives offset values for correcting the original magnetic detection data and generating corrected magnetic detection data. The offset derivation device uses a plurality of data points in the original magnetic detection data or in the corrected magnetic detection data to derive provisional offset values, then derives the magnitude of magnetism on such an occasion on the basis of the original magnetic detection data and the provisional offset values. When the magnitude of magnetism thus derived is within a predetermined correction success range, the offset values are updated using the provisional offset values. When the magnitude of magnetism thus derived is not within the predetermined correction success range, the offset values are not updated.

Abstract: The present invention involves a test subject performing a sit-to-stand (STS) operation while wearing a device (MD) that contains an acceleration sensor (11) on the front of the chest. The present invention derives a muscular strength index (maximum acceleration value per unit of muscle mass during STS activity) representing the muscular strength of a human body by obtaining maximum acceleration value data from a signal expressing the size of an acceleration vector comprising a tri-axial component in detected acceleration, and using the maximum acceleration value data and the muscle mass or body fat mass of the text subject.

Abstract: A subject performs a sit-to-stand operation while wearing a device (SU) that contains an acceleration sensor (11) on the front of the chest. The present invention derives a muscular strength index representing the muscular strength of a human body by obtaining maximum acceleration value data from a signal expressing the size of an acceleration vector comprising a tri-axial component in detected acceleration, and using the maximum acceleration value data and the muscle mass or body fat mass of the subject. The present invention has the ability to derive a physical activity amount from the acceleration detection results, and on the basis of the activity amount (ACT) during a prescribed activity target period and the muscular strength index at the start and end times of the activity target period, obtains an activity efficiency index that corresponds to changes in the muscular strength index in response to the amount of activity.

Abstract: For triaxial magnetic detection data sequentially acquired as data points in a triaxial coordinate system, an offset calculation unit 30 calculates virtual data points P1?-P6? by evenly parallel-translating each of data points P1-P7 so that a reference data point P7, for example, arbitrarily chosen from the data points P1-P7 coincides with an origin point O. A virtual offset point C? for which the sum of the distances between the virtual data points P1?-P6? and a curved surface H1 passing through the origin point O is minimized is then calculated. An offset value C for the magnetic detection data is then calculated by parallel-translating the virtual offset point C? so as to restore the parallel-translated portion.

Abstract: A decoding device improves a cache hit rate in a decoding process of compressed encoded image data. The decoding device, before the decoding process, generates a sort table for each reference picture for a plurality of MPEG data streams included in a GOP and having a frame type of P- or B-picture. The decoding device, by using the generated sort table, selects a group of pictures composed of a plurality of decoding target macro blocks that refer to the same reference macro block. The decoding device obtains, from the reference picture, four macro blocks including the same reference macro block referred to by the selected picture group, and stores the four macro blocks into the cache memory. The decoding device sequentially decodes each decoding target macro block included in the selected picture group, by using the four macro blocks stored in the cache memory.

Abstract: A vibration device separates foreign particles from a semiconductor device, and a suction interface of a suction device covers an opening portion of the semiconductor device. A space connected with a vacuum passage and a communication passage is formed between the semiconductor device and the suction interface. The suction device suctions the space, and fresh air is introduced into the space through the communication passage. As a result, a current of air is generated from the communication passage to the vacuum passage, and foreign particles are suctioned and removed from the space.
