Abstract

A sensor unit includes a sensor section adapted to detect a motion, and an announcement section adapted to announce a state of an output signal of the sensor section.

Claims

1. A sensor unit comprising:

a sensor section adapted to detect a motion of a measurement object; and

an announcement section adapted to announce whether or not the measurement object is in a rest state.

2. The sensor unit according to claim 1, wherein

the announcement section performs a first determination on whether or not a value of an output signal of the sensor section becomes lower than a first threshold value in a predetermined period, and announces a result of the first determination.

4. The sensor unit according to claim 1, wherein

the announcement section announces whether or not transmission of an output signal of the sensor section to another device connected to the sensor unit is complete.

5. The sensor unit according to claim 1, wherein

the announcement section makes an announcement using at least one of light, a sound, and a vibration.

6. The sensor unit according to claim 1, further comprising:

a housing adapted to house the sensor section,

wherein at least a part of the announcement section is disposed on a side surface of the housing.

7. The sensor unit according to claim 1, further comprising:

a holding section adapted to attach a housing to the measurement object, the holding section adapted to house the sensor section,

wherein at least a part of the announcement section is provided across ends of the holding section.

8. A motion detection device comprising:

the sensor unit according to claim 1; and

an analysis unit adapted to analyze the motion of the measurement object.

10. The motion detection device according to claim 8, wherein

the sensor unit transmits an output signal of the sensor section to the analysis unit,

the analysis unit analyzes the output signal, and then transmits a trigger signal to the announcement section of the sensor unit when a predetermined condition is fulfilled, and

the announcement section makes an announcement upon reception of the trigger signal.

12. The sensor unit according to claim 1, the announcement section adapted to announce when the measurement object is in the rest state and to announce when the measurement object is not in the rest state.

15. The sensor unit according to claim 1,

the announcement section including an output unit adapted to provide signals to a user,

the announcement section being adapted to announce a plurality of states of the sensor unit using differences in the signals provided to the user.

3. A sensor unit comprising:

a sensor section adapted to detect a motion of a measurement object; and

an announcement section adapted to perform a second determination on whether or not a value of an output signal of the sensor section exceeds a second threshold value, and announce a result of the second determination.

9. A motion detection device comprising:

the sensor unit according to claim 3; and

an analysis unit adapted to analyze the motion of the measurement object.

11. The motion detection device according to claim 9, wherein

the sensor unit transmits an output signal of the sensor section to the analysis unit,

the analysis unit analyzes the output signal, and then transmits a trigger signal to the announcement section of the sensor unit when a predetermined condition is fulfilled, and

the announcement section makes an announcement upon reception of the trigger signal.

13. The sensor unit according to claim 3, the announcement section adapted to announce when the measurement object is in the rest state and to announce when the measurement object is not in the rest state.

14. A sensor unit comprising:

a sensor adapted to detect a motion of a measurement object;

an analysis device adapted to determine, based on the detected motion of the measurement object, whether the measurement object is in the rest state or is not in the rest state;

an announcement device adapted to announce that the measurement object is in the rest state when the analysis device determines that the measurement object is in the rest state, and to announce that the measurement object is not in the rest state when the analysis device determines that the measurement object is not in the rest state.
