Attachable toothbrush'S posture or movement tracking device

An attachable apparatus, comprising:

• a housing having an accommodation space;
• a sensor disposed in the accommodating space and configured to sense at least one of posture or movement of a toothbrush and generate a sensing signal;
• a circuitry disposed in the accommodating space and configured to process the sensing signal;
• and
• an elastic fastening member including one portion coupled with the housing and the other portion coupled with a toothbrush handle,
• wherein the other portion of the elastic fastening member having a toothbrush insertion groove configured to insert a portion of the toothbrush handle,
• wherein the sensor includes a three-axis sensor includes a circuitry element senses at least one of toothbrush's posture and movement information to the sensed signal, and
• wherein the circuitry element detects a load state of the toothbrush in response to at least one of oscillation frequency and amplitude change of the sensed signal.

An attachable apparatus, comprising:

• a housing having an accommodation space;
• a sensor disposed in the accommodating space to sense at least one of a toothbrush's posture and movement;
• and
• a sensing circuitry disposed in the accommodating space to process sensing signals of the sensor,
• wherein the sensing circuitry detects a load state of the toothbrush in response to at least one of a vibration frequency and an amplitude of the sensed signals, and
• wherein the sensor includes a three-axis acceleration sensor, and wherein the sensing circuitry includes a circuitry part converting a sensor signal to at least one of toothbrush's posture and movement information, a wireless transmitter transmits the information, and a battery supplies a power to the three-axis acceleration sensor and the wireless transmitter.
