An oral-care system includes an oral-care device having a treatment head, a position-determination unit for determining position information of the treatment head in relation to a user's treatment area at a plurality of time instances during a treatment session, a sensor unit for determining treatment-parameter values of at least one treatment parameter at the plurality of time instances, a processor unit for processing the determined position information and the determined treatment parameter values to generate at least position-resolved treatment data, a memory unit for storing at least the position-resolved treatment data, and a control unit for triggering an action of the personal-hygiene system based at least on a current position information and on the stored position-resolved treatment data.

Personal-hygiene system

A device and a method for determining a position of a user's body portion. The device includes a camera, configured to capture the body portion, and a display for providing visual feedback. A sensor determines at least one of a roll angle, a pitch angle, and a yaw angle of the device, and an interface receives picture data related to a pictorial representation of the body portion captured and sensor data related to the determined angle of the device. An analyzer analyzes, based on the picture data, whether the captured body portion is within a predetermined region of the picture and, based on the sensor data, whether at least one of the roll angle, the pitch angle, and the yaw angle is within a predetermined angle range. The method includes capturing the body portion, providing visual feedback, receiving angle data, receiving picture data, and analyzing whether the captured body portion is within a predetermined region and whether at least one of the roll, pitch, and yaw angles is within a predetermined angle range.

Interactive system setup concept

An apparatus for determining a body portion of a user treated by the user using a personal hygienic device. The apparatus includes a camera configured to capture the user to obtain a pictorial representation of the user while treating the body portion using the personal hygienic device; an interface configured to receive sensor data from at least one inertial sensor residing in the personal hygienic device; and an analyzer configured to analyze the pictorial representation and the sensor data to determine the body portion.

The present invention provides for a fastenable device for oral area position detection that is fastenable to oral care implements.

Fastenable device for oral cavity position detection

A personal hygiene system includes a personal hygiene device having a receiver unit, a control unit, and a functional unit; and a separate control device having a transmitter unit. The control unit drives the functional unit in at least one of a first functional mode and a second functional mode different from the first functional mode. The control unit inhibits provision of the second functional mode while the control unit is in a default state. The transmitter unit sends at least a first signal to the receiver unit of the personal hygiene device when the separate control device is switched from a default control mode to a first control mode. The control unit can be switched from the default state into a first state when the first signal is received by the receiver unit, in which first state the control unit permits provision of the second functional mode at least during a first allowance period.
