The invention relates to a toothbrushing monitoring device (). In order to obtain an efficient monitoring device, the monitoring device comprises: an input device (), an acceleration sensor, a signal conditioner, a memory, a comparator which compares the numbers of brushing cycles registered by each teeth surface specific counter during brushing with corresponding reference values maintained in said memory, and an output device () which indicates that the brushing of the teeth region (L-U) in question is accepted.

Toothbrush monitoring device

The invention shows a method to control a pointing device with an angular, rate sensor, that comprises generating an ensemble of orthogonal unit vector associated signals by at least one angular rate sensor to represent angular rates in a dimensional space for each mutually orthogonal unit vector direction of said dimensional space, amplifying the at least one of said signal non-linearly for determination of cursor on a screen for (x,y) coordinates of the screen, applying a decision criterion to determine the state of the pointing device as based on said unit vector associated signals. The invention also shows a pointer utilizing the method and a system comprising such a pointer.
