Abstract: A step count detection unit detects one step (a step count) on the basis of the acceleration from an acceleration sensor, and outputs the detection result to an acceleration accumulation unit. The acceleration accumulation unit calculates, within a period of time corresponding to the one step detected by the step count detection unit, an acceleration cumulative value (simple posture pitch angle) by accumulating the acceleration detected by the acceleration sensor. The posture detection unit detects, on the basis of the acceleration cumulative value calculated by the acceleration accumulation unit, the posture of a portion for which the acceleration sensor is provided.

Abstract: A position detection system according to an embodiment of the present invention includes a plurality of fixed stations 20; and a sensor unit 10 including an inertial sensor that detects movement history of a mobile body 51 and a distance sensor that detects separation distances between the mobile body 51 and the fixed stations 20. A position of the mobile body 51 is determined by detecting a first arrival position P1 obtained based on the movement history, a second arrival position P2 obtained based on the separation distances, and a relative distance L1 between the first arrival position P1 and the second arrival position P2, and by comparing a range value R1 obtained based on the movement history with the relative distance L1. The range value R1 is changed based on the movement history.

Abstract: In a position detection system that has a plurality of transmitters/receivers placed at least three positions: processing is executed to measure distances among the plurality of transmitters/receivers, each distance being measured a plurality of times, and obtain a minimum value for each distance; processing is executed to obtain an angle between each two adjacent straight lines, each of which is one of straight lines that mutually connect the plurality of transmitters/receivers, by using minimum values, each of which is the minimum value for each distance; and if the absolute value of the difference between 180 degrees and the sum of angles, each of which is the angle between each two adjacent straight lines, inside a triangle formed by straight lines that interconnect three of the plurality of transmitters/receivers is smaller than a predetermined value, processing is executed to take the minimum values as the true values of the distances.

Abstract: A tilt adjusting image including a captured image that is obtained by capturing a wearer wearing a spectacle-type electronic device, and a horizontal line image indicating a horizontal direction identified by a tilt identification part, is displayed. The wearer adjusts a position of the spectacle-type electronic device by a wearer's hand or the like while viewing the tilt adjusting image so that the spectacle-type electronic device becomes horizontal. When the wearer judges that the spectacle-type electronic device has become horizontal, the wearer operates an operation part and inputs a calibration instruction. When the calibration instruction is input, the calibration instruction is transmitted to the spectacle-type electronic device.

Abstract: A position detection system performs first through third processes to measure, using high-frequency signals, a position of a slave device in a measurement area surrounded by parent devices. The first process measures distances between the slave device and each of the master devices a plurality of times, to obtain a minimum value of each of the distances. The second process obtains a position of an intersection point of two arcs among arcs respectively having the minimum value of each of the distances as a radius from respective centers of the master devices when a number of intersection points of the two arcs within the measurement area is one. The third process regards a center of gravity of the intersection points as a true position of the slave device when the intersection points are densely arranged.

Abstract: Accelerations (Ax, Ay, Az) in directions along (X′, Y′, Z′) detected by an acceleration sensor 10 are converted, based on a correction angle γ, which is an angle between a first detection axis X′ and a first posture axis X, into accelerations (Bx By, Bz) in directions along three posture axes (X, Y, Z). A pitch angle α and a roll angle ß, which indicate a posture of a portion to which the wearable device is attached, are calculated based on the accelerations (Bx By, Bz) obtained by the conversion based on the correction angle γ.

Abstract: An operation signal generating unit 11 and a reset unit 12 are included in a first circuit unit 10 that operates based on a first power supply voltage V1 and an output operation of a second power supply voltage B2 is stopped by outputting a reset signal Sr from the reset unit 12 to a regulator 20 in accordance with an operation signal Si of the operation signal generating unit 11. Hence, unlike a conventional technique, a large transistor for cutting off a power supply line is unnecessary, and therefore a device size can be reduced.
