An oral care system and method for applying a fluid to an oral surface, including a method of manufacturing the same. In one embodiment, the invention can be an oral care system comprising: a toothbrush; and a dispenser detachably coupled to the toothbrush, the dispenser comprising: an internal reservoir containing a fluid; and a conduit in fluid communication with the reservoir and terminating in an orifice for dispensing the fluid; and a plug having a proximal plug portion disposed within the conduit and a distal plug portion disposed within a socket of the toothbrush.

The present invention relates to a new optical component comprising an anisotropic diffuser (5,10) with patterned anisotropy; and means (9, 11, 14, 16, 17, 20, 21, 30, 32) for providing a colorshift observable upon changing viewing angle (6) and / or changing angle of incident light (2). It also relates to methods for making such an optical component and uses of such optical components as security elements with a very high level of security.

The invention aims at providing an electromagnetic semi-active vibration isolator achieving the quasi-zero rigidity characteristic through an asymmetric magnetic tooth structure. The electromagnetic semi-active vibration isolator comprises supporting plates, end covers, armatures, shells and bases. The end covers are arranged above the shells through screws. The bases are arranged below the shells through screws. The armatures are arranged in the shells. Shafts are installed in the centers of the armatures. The supporting plates are arranged above the end covers. First mechanical springs are arranged between the supporting plates and the end covers. Supporting columns are arranged in the first mechanical springs. The upper ends of the supporting columns are connected with the supporting plates through screws. The lower ends of the supporting columns penetrate the end covers and are connected with the armatures. First linear bearings and second linear bearings are arranged between the armatures and the shafts. Shaft sleeves are arranged between the first linear bearings and the second linear bearings. Second mechanical springs are arranged between the armatures and the end covers. Third mechanical springs are arranged between the armatures and the bases. The negative rigidity can be changed by adjusting the current, and accordingly system quasi-zero rigidity is easier to obtain.

The invention relates to an electrolytic type oxy-hydrogen generation device which comprises an electrolytic cell, an evaporator and a tempering prevention device which is connected with the outlet of the evaporator, wherein a cooling pipe which is connected with a compressor is arranged in the evaporator, the electrolytic cell is connected with a direct current power supply and arranged in a closed tank body to from an isopiestic body and consists of a set of standard masterplate type electrode baffles and water diversion baffles, the water diversion baffles are in a frame structure, diversion stiffeners are arranged at both ends of each water diversion baffle in a staggering way, and each baffle are sealed and fixed at the edge part. Based on the electrolytic cell structure and a circulating system, designed in the invention, an electrode distance between every two electrode baffles in the electrolytic cell can reach below 2mm without resulting in the phenomena of short circuit, arcing and the like between every two electrodes, thereby achieving the purposes of normal running of the electrolytic cell with low voltage and large current, greatly enhanced electrolysis efficiency, energy saving and environmental protection.

The invention relates to an apparatus for connection to a gearbox actuating element of an engine gearbox, having sensors (5, 6, 7) for sensing gearbox shifting positions of a shifting apparatus, and to an interface (2) for transferring the evaluation signals of the sensors (5, 6, 7) to the control electronics of a gearbox actuating element, wherein the sensors (5, 6, 7) are arranged in such a way that their spacing from the interface (2) is smaller than the spacing between the interface (2) and the shifting apparatus which is to be sensed.
