  • Patent number: 10760322
    Abstract: In a state that an engine is started up by using a mobile device from outside a vehicle, a power mode changeover switch is switched from a fixed contact OFF to a fixed contact START while avoiding a fixed contact ACC and a fixed contact ON, and the power mode changeover switch is maintained at the fixed contact START even after the engine is placed in an operation state. When an electric power is not supplied through the fixed contact ACC, a detection unit places itself in a state in which a detection operation is possible, and when the electric power is supplied, the detection unit places itself in a detection operation prohibition state.

  • Publication number: 20100152549
    Abstract: A biological information detection apparatus includes a sensor, a memory unit, and a control unit. The sensor is worn by a subject and continuously detects the biological information of the subject. The memory unit stores biological information detected by the sensor. The control unit takes control so that a predetermined part of the biological information stored in the memory unit is transmitted to a management apparatus on a regular basis. The control unit takes control so that, when the biological information detected by the sensor exceeds a predetermined reference value, the amount of information, which is larger than the amount of information regularly transmitted, is transmitted to the management apparatus.

  • Patent number: 7194816
    Abstract: A mobile terminal apparatus 1 uses an acceleration sensor as a tilt angle sensor 24, and realizes various applications based on this detection result. A processing unit 10 counts the number of steps of a human based on acceleration components of low frequency detected by the tilt angle sensor that detects the acceleration components. At that time, the acceleration component of an axis among three axes which most approximates a gravity axis is mainly used. A viewpoint relative to a three-dimensional object or a three-dimensional space displayed on a display unit 36 is moved. By effectively utilizing the detection result of the tilt angle sensor, it is possible to realize a mobile terminal apparatus 1 featuring greater usefulness.

  • Patent number: RE45023
    Abstract: A hybrid three-axis magnetic sensor for calculating the accurate direction of the earth magnetism. The hybrid three-axis magnetic sensor includes: a flux gate type magnetic sensor which is so formed that a base serves as a main member and detects two axis components of a magnetic vector defined by a plane parallel to the base; a Hall element which detects another component of the magnetic vector orthogonal to the base; a tilt sensor which detects a tilt angle of the base; and a CPU, wherein the flux gate type magnetic sensor and the Hall element are integrally structured together as a hybrid IC. The thus detected three dimensional magnetic vector is corrected in the light of inclination of the base, so that the direction of the earth magnetism is accurately calculated.
