    • Disclosed is an electric toothbrush (1) comprising a handle part (2) and an attachment part (3), e.g. a bristle head (4). Preferably, the bristle head (4) can be driven by a first drive unit (6.1) encompassing a first electric motor (7.1). A reservoir (8.1) for a care substance is connected to a duct (11.1) extending into the bristle head (4) by means of a pump (10.1) which can be driven by a second drive unit (6.2) encompassing a second electric motor (7.2). The first and the second electric motor (7.1, 7.2) are powered by a disposable or a rechargeable battery (12). A housing (16) of the handle part (2) is subdivided into a first and a second chamber (19, 20) by means of a liquid-tight partition (17) that extends in the longitudinal direction of the handle part (2). The first and the second drive unit (6.1, 6.2) and the disposable or rechargeable battery (12) are arranged in the first chamber (19) while the reservoir (8.1) and the pump (10.1) are disposed in the second chamber (20). The pump (10.1) can be driven by the second drive unit (6.1) via a lever (15), pumping movements (A′-B′) being transmitted from the lever (15) to the pump (10.1) via an integrated soft membrane (18) of the partition (17) by means of non-positive contact or via a liquid-tight slide passage (21) in the partition (17).
    • 公开了一种电动牙刷(1),其包括手柄部分(2)和附接部分(3),例如, 刷毛头(4)。 优选地,刷毛头(4)可以由包围第一电动机(7.1)的第一驱动单元(6.1)驱动。 用于保养物质的储存器(8.1)通过泵(10.1)连接到延伸到刷毛头(4)中的管道(11.1),泵(10.1)可以由包括第二电动机的第二驱动单元(6.2)驱动 (7.2)。 第一和第二电动机(7.1,7.2)由一次性或可再充电电池(12)供电。 手柄部分(2)的壳体(16)通过在手柄部分(2)的纵向延伸的液密分隔件(17)被细分为第一和第二腔室(19,20) 。 第一和第二驱动单元(6.1,6.2)和一次性或可充电电池(12)被布置在第一室(19)中,同时储存器(8.1)和泵(10.1)设置在第二室(20) )。 泵(10.1)可以经由杆(15)由第二驱动单元(6.1)驱动,泵(15)的泵运动(A'-B')通过一体式软件 通过非正接触或通过分隔件(17)中的液密滑动通道(21),隔板(17)的隔膜(18)。

    • A central operating input and information output system for the control of a plurality of optional instruments in a vehicle has a display for displaying information and an option menu. A first control input controls the functions of the optional instruments and selects the option menu from a basic menu. The option menu indicates the functions of the optional instruments controllable by the first control input. The system has a second control input which controls at least one optional instrument and accesses at least one basic function of the system, irrespective of the option menu currently selected. This allows a central operating input and information output system to have a favorable ergonomic design, to be operated simply, and require a minimum of space. In addition, a high degree of safety is insured by the simplified controls, which minimizes the diversion of the driver from the traffic situation, while allowing him to obtain extensive information concerning the condition of the vehicle and the traffic situation.
    • 用于控制车辆中的多个可选仪器的中央操作输入和信息输出系统具有用于显示信息和选项菜单的显示。 第一个控制输入控制可选仪器的功能,并从基本菜单中选择选项菜单。 选项菜单指示可由第一个控制输入控制的可选仪器的功能。 该系统具有控制至少一个可选仪器并且访问系统的至少一个基本功能的第二控制输入,而与当前选择的选项菜单无关。 这允许中央操作输入和信息输出系统具有有利的人机工程学设计,简单地操作,并且需要最小的空间。 另外,通过简化的控制,保证驾驶员从交通状况上的转移,使他获得有关车辆状况和交通状况的广泛信息,从而保证了高度的安全性。

    • The present disclosure relates to an apparatus and method for estimating a parameter of interest in a downhole fluid using a fluid analysis module. The fluid analysis module may include: a first transducer configured to generate a surface wave in a fluid. The first transducer may include one or more of: a piezoelectric crystal, a electromagnetic transducer, and a surface acoustic wave crystal. The apparatus may use the first transducer or a second transducer to generate a signal indicative of the dissipation of the surface wave in the fluid. The apparatus may include a compensator configured to reduce mechanical pressure on the transducer. The method may include estimating a parameter of interest of the fluid using a signal indicative of the dissipation of the surface wave.
