Abstract: A treating system includes a controller and a treating device having a treating unit for treating a part of a body of a subject. An imaging arrangement is configured to obtain image data. The controller is configured to analyze the image data to identify a boundary between the part of the body of the subject and the environment around the part of the body; and determine the position of the treating device relative to the part of the body of the subject based on a position of the boundary in the image data.

Abstract: There is provided a treating system, comprising a controller; and a treating device, the treating device comprising a treating unit for treating a part of a body of a subject; and an imaging arrangement that is configured to obtain image data; wherein the controller is configured to analyse the image data to identify a boundary between a part of a body of a subject and the environment around the part of the body; and determine the position of the treating device relative to the part of the body of the subject based on a position of the boundary in the image data.

Abstract: A tap sensitive alarm clock has a housing (20), a vibration sensor (22) mechanically coupled to the housing for receiving a shock due to a user tapping the housing, and a control circuit (24) coupled to the vibration sensor for controlling a function of the alarm clock. An audio unit (26) is coupled to an audio circuit (25) for generating sound, e.g. a loudspeaker in an alarm clock or a wake up light. To avoid interference of the sound and the vibration sensor, the alarm clock is provided with a filter (23) coupled to the vibration sensor and the control circuit. The filter has a filter curve matched to block frequencies occurring in the sound. Advantageously it is avoided that the sound frequencies trigger the function, while the sensor is sensitive to other frequencies up to the frequency range of the sound for reliably detecting the tapping.
