摘要： The invention relates to a hygiene device, having a material body, which covers a region in the intended positioned state, and in particular has multiple plies (a, b, c) of material, in particular moisture absorption material, which is made of a plastic material, wood, paper, and/or granular material, wherein the hygiene device has at least one sensor (4) for measuring a parameter. It is proposed that the hygiene device has at least one transmitter module (5) on or in the material of the material body, the at least one sensor (4) is integrated in the transmitter module (5), and the transmitter module (5) is designed for the contactless transmission of sensor data of the at least one sensor (4) and without its own electrical energy source.

摘要： A spindle for a disc drive which can be assembled without the use of adhesives is disclosed. Stator electromagnets are encapsulated in a plastic overmold. The stator is clamped to the base with a clamp spring arrangement. An offset between the stator surface and the base flange is covered by a clamp spring such that binding of the clamp spring by a fastener allows for an adjustable biasing force to secure the stator in place. The magnet and flux shield are attached to the rotor sleeve by an easily positioned retaining ring. An elastic foam washer provides a controlled force to secure the magnet and flux shield in place on the rotor. A second elastic foam washer and a shield provide a controlled biasing force to hold magnetic fluid and magnetic poles to the rotor. Bearings are laser welded to the rotor and the shaft to rotatably mount the rotor about the shaft.

摘要： A vibration generator causes a carrier to oscillate, rather than the housing of the vibration generator. The vibration generator is placed within the housing, which itself is not induced to oscillate, thus reducing or eliminating undesired noises due to excessive oscillations of the housing. The vibration generator transfers vibrations to the carrier for Petri dishes using at least one connecting element that is arranged between the carrier and the vibration generator. The connecting element protrudes through the wall of the housing and is sealed by a sealing element with respect to the wall.

摘要： A head-arm assembly having a pair of trapezoidal-like shaped coil bobbins for improved torque and moments of inertia in a voice coil motor (VCM) for a disk drive. The VCM includes a magnetic structure that employs three magnet polarity zones having two flux transition zones. The magnetic structure is able to employ relatively thin pole pieces without saturation or leakage. The thin pole pieces permit use of a thicker magnet in the same envelope size. The result is an increased flux density in the air gap of the VCM, giving higher torque and shorter access time. In addition to improving the torque and moments of inertia, the present invention allows use of thicker magnets (thinner pole pieces) and allows the option of using a thinner coil that is wider radially. In another version, an oval-shaped coil may be used for increased effective length when disposed within a magnetic field of a VCM.
摘要翻译：一种头臂组件，具有一对梯形线状线圈架，用于在用于磁盘驱动器的音圈电机（VCM）中改善扭矩和转动惯量。 VCM包括采用具有两个磁通过渡区域的三个磁极区域的磁结构。磁性结构能够使用相对薄的极片而没有饱和或泄漏。薄极片允许使用相同信封尺寸的较厚磁铁。结果是VCM气隙中的磁通密度增加，提供更高的扭矩和更短的存取时间。除了提高扭矩和转动惯量之外，本发明还允许使用较厚的磁体（较薄的极片），并且允许使用更宽的径向更薄的线圈的选择。在另一种形式中，当设置在VCM的磁场内时，可以使用椭圆形线圈来增加有效长度。
