A system for classifying the usage of a handheld consumer device having a sensor and an analyzer. The sensor determines usage data at successive time instants and provides a temporally successive sequence of usage data during a usage session. The analyzer classifies the usage of the device with respect to at least one set usage classes and assembles a temporally successive sequence of input tuples of usage data relating to a predetermined time period of the usage session, each of the input tuples having at least one element representing the usage data at the respective time instant and for inputting the sequence of input tuples into at least one artificial neural network arranged to output at least one output tuple comprising a number of elements in accordance with the number of usage classes, each element of the output tuple representing a prediction value that the usage of the consumer device at the given time instant relates to a respective usage class.

An electric toothbrush includes a handle with a motor and a light source located in a proximal end. A brush head is in a distal end of the toothbrush, and a drive shaft conveys kinetic energy from the motor to the brush head. The drive shaft includes a light guide from the light source to the distal end and contains two layers of an optical medium of differing refractive indices to enable TIR within the light guide. The brush has a tuft plate having bristles and is made of a polymer such that the water contact angle of the tuft plate is less than 90 degrees and is at least partially transparent. The handle and the tuft plate have electrical contacts to make a contact sensor and a movement sensor provides movement data. A computing device processes movement and contact data to determine when to activate the light.

Tooth brushing monitoring system is disclosed that includes a toothbrush with sensors and a base station. The sensors record data regarding the quality, quantity and location of brushing and the system can analyze the data to provide feedback on the quality of brushing. This feedback provides motivation for users to increase their brushing habits, leading to a decrease in plaque, tooth decay and gingivitis
