Abstract
The subject-matter of the present disclosure relates to a personal care apparatus. The personal care apparatus comprises: a handle; a head at an end of the handle and having a connection portion for a device to connect to and disconnect from; an inertial measurement unit, IMU, sensor within the handle; and a controller. The controller is configured to: monitor measurements from the IMU sensor over time; compute one or more measurement values from the monitored measurements; identify a connection event or a disconnection event when the one or more measurement values fall within a classification boundary; and output the identified connection event or disconnection event as a signal.
Claims13
A personal care apparatus (10) comprising:
- a handle (12);
- a head (14) at an end of the handle and having a connection portion (16) for a device (18) to connect to and disconnect from;
- an inertial measurement unit, IMU, sensor (40) within the handle (12);
- and
- a controller (42) configured to:
- monitor measurements from the IMU sensor (40) over time;
- compute one or more measurement values from the monitored measurements;
- identify a connection event or a disconnection event when the one or more measurement values fall within a classification boundary (50);
- and
- output the identified connection event or disconnection event as a signal,
- wherein the IMU comprises an accelerometer for measuring acceleration and a gyro for rotational velocity.
A computer-implemented method of detecting a connection event in response to connecting a device (18) to a connection portion (16) of a head (14) of a personal care apparatus (10), or detecting a disconnection event in response to disconnecting the device (18) from the connection portion (16) of the head (14) of the personal care apparatus (10), the computer-implemented method comprising:
- monitoring (S1) measurements from an inertial measurement unit, IMU, sensor (40) over time, the IMU sensor (40) positioned within a handle (12) of the personal care apparatus (10), the head (14) at an end of the handle (12);
- computing (S2) one or more measurement values from the monitored measurements;
- identifying (S3) a connection event or a disconnection event when the one or more measurement values fall within a classification boundary (50);
- and
- outputting (S4) the identified connection event or disconnection event as a signal,
- wherein the IMU comprises an accelerometer for measuring acceleration and a gyro for rotational velocity.
