摘要： A radio frequency (RF) die package includes a switch assembly comprising an RF transmission line and a plurality of conductive mounting pads formed on a first substrate. A switching mechanism selectively couples a first portion of the RF transmission line to a second portion of the RF transmission line. An inverted ground plane assembly is coupled to the plurality of conductive mounting pads such that an electromagnetic field generated between the RF transmission line and the inverted ground plane assembly does not permeate the first substrate in a region of the switch assembly proximate the switching mechanism.

摘要： A flexible magnetic membrane based actuation system comprising magnetic nanoparticles loaded into a polymeric material such as polyurethane and adapted to actuation of to and fro pumping motions of the membrane under application of magnetic field on the magnetic nanoparticles loaded membrane. More particularly, the present invention is directed to the said nanoparticles-loaded polyurethane magnetic membrane based actuation system adapted to function as displacement membrane for various activities requiring such to and fro motion. The magnetic membrane actuation is adapted to be controlled using electronic equipments to regulate the rate, force and frequency of displacement pulses. The magnetic membrane is thus capable of providing a simple, bio-compatible and cost effective means for displacement/mechanical work to assist functioning of various gadgets/medical devices including function as an artificial support system for heart, non-responsive diaphragm or a non-responsive sphincter, and thus capable of wide industrial applications.

摘要： Conventional devices have a valve needle and a shape memory element which, by the application of a controllable magnetic field, executes a control stroke travel that operates the actuator, and having a coil that excites the magnetic field which is situated in a magnet housing which, at its end face, is bordered with respect to an actuating axis by a front wall in each case, the front walls having a through opening radially within the coil. It is a disadvantage that the magnetic field excited around the coil is conducted unfavorably, so that at most a slight magnetic field develops in the shape memory element. The shape memory element has a magnetic field flowing through it, in the direction of its longitudinal extension, if at all. Since the shape memory element has a high magnetic resistance and is developed to be very long in the axial direction, only a very weak magnetic field can be induced in the shape memory element. In response to the magnetic field that is weak at most, the shape memory element can generate only a very slight lift of the valve needle. In the device according to the present invention, a strong magnetic field is conducted through the shape memory elements, and in this way, a large control stroke travel is achieved. The shape memory element(s) is/are positioned generally only in the through opening(s).
摘要翻译：常规装置具有阀针和形状记忆元件，其通过施加可控磁场来执行操作致动器的控制行程行程，并且具有激励位于磁体壳体中的磁场的线圈，在其端面处，在每种情况下通过前壁相对于致动轴线相邻，前壁具有径向在线圈内的通孔。不利的是，线圈周围激发的磁场是不利的，因此在形状记忆元件中最多产生轻微的磁场。形状记忆元件具有在其纵向延伸的方向上流经的磁场，如果有的话。由于形状记忆元件具有高磁阻并且在轴向上被显影为非常长，所以在形状记忆元件中只能产生非常弱的磁场。响应于至多为弱的磁场，形状记忆元件可以仅产生非常轻微的阀针的提升。在根据本发明的装置中，通过形状记忆元件传导强磁场，从而实现了大的控制行程行程。形状记忆元件通常仅定位在通孔中。
