摘要:
An interdental treatment device, such as a toothbrush, includes a handle configured to accommodate an electric power source, a head carrying an interdental treatment tool, and a neck between the handle and the head. The head or neck includes a mechanical motorized vibratory device, including a drive which causes the head to vibrate. Electrical connections are operably connected to the mechanical vibratory device and the electric power source to power the mechanical vibratory device via the electrical connections. At least parts of the electrical connections are formed by tracks of an electrically conductive plastic material. In various embodiments, a vibration-damping structure dampens vibration transmission from the head to the handle.

摘要:
In a projection system for projecting a video picture composed of picture points on a screen with at least one light source which emits a light bundle and can be varied in intensity and with a deflecting device which deflects the light bundle to illuminate the picture points on the screen, a transformation optical system having at least two stages is arranged between the deflecting device and the screen and is corrected according to the tangent condition so as to be free of distortion. The transformation optical system has at least two optical stages. The first optical stage produces an intermediate image plane which is imaged on the screen by means of the subsequent optical stage (s).
