    • A power toothbrush (10) is disclosed having a handle (15), battery (12), ultrasonic drive circuit (14), motor (16), control unit (18), and toothbrush head (20). The toothbrush head includes bristles (26) and a waveguide (24) that is operatively connected to an ultrasonic transducer (22). The waveguide facilitates the transmission of acoustic energy into the dental fluid to achieve improved cleaning and stain removal and improved cleaning in interproximal and subgingival regions. In one embodiment an ultrasound transducer module (30) includes a plurality of piezoelectric elements (32, 34) that may be mechanically connected in series, and electrically connected in parallel. One or more contacts (36) connect the elements, and a waveguide structure (50). An impedance matching layer (38) may be provided between the waveguide and the ultrasonic transducer module. The waveguide may be formed from an relatively soft material, for example, a polymer having a hardness between 10 and 65 Shore A.
    • 公开了具有手柄(15),电池(12),超声波驱动电路(14),马达(16),控制单元(18)和牙刷头(20)的动力牙刷(10)。 牙刷头包括刷毛(26)和可操作地连接到超声换能器(22)的波导(24)。 波导有助于将声能传输到牙科液体中,以实现改善的清洁和污渍去除以及改善邻近和龈下区域的清洁。 在一个实施例中,超声换能器模块(30)包括多个压电元件(32,34),其可以串联机械连接并并联电连接。 一个或多个触点(36)连接元件和波导结构(50)。 可以在波导和超声换能器模块之间设置阻抗匹配层(38)。 波导可以由相对柔软的材料形成,例如硬度在10和65肖氏A之间的聚合物。

    • A golf swing training aid kit comprising three golf practice aids, each of which can be used independently or all three may be used together. The kit, a brief-case sized box opens to form a platform. A self-contained collapsible pole is affixed therein and is adjusted for user height. The pole, held rigidly upright by means of struts and the golfer's weight while standing on a portion of said box, further comprising horizontal bars which provides passive limits to the motion of the golfer's hips.A second aid comprises a chest harness to which a lanyard is attached and whereby said lanyard's free end is looped around the center most part of a golf club's hand grip. Thereby, training the golfer in correct arm and wrist movement.The third related aid, a brightly colored ribbon having eyelets, for attaching ground anchors, for marking out the correct path to be followed by the club head during the golfer's swing. Each of the three aids independently address different aspects of a golfer's swing whereas all three address most of the golfer's swing problems.
    • 一种高尔夫挥杆训练辅助工具包,包括三个高尔夫球练习辅助器,每个辅助工具可以独立使用,也可以全部三个使用。 该套件,一个简短大小的盒子打开形成一个平台。 将独立的可折叠的杆固定在其中,并根据使用者的高度进行调整。 杆杆在站立在所述箱体的一部分上时通过支柱和高尔夫球手的重量刚性地竖立,还包括水平杆,其为高尔夫球手的臀部的运动提供被动限制。 第二辅助装置包括挂绳挂在其上的胸带,由此所述挂绳的自由端围绕高尔夫球杆的手柄的大部分中心环绕。 因此,训练高尔夫球手正确的手臂和手腕运动。 第三个相关的辅助工具,一个带有孔眼的明亮色带,用于连接地面锚,用于标记高尔夫球员挥杆期间球杆头所遵循的正确路径。 这三种辅助工具中的每一种都独立地解决了高尔夫球员挥杆的不同方面,而所有这三种技能都解决了高尔夫球手摆动问题的大部分。
