摘要： A micro-electromechanical device includes a semiconductor body, in which at least one first microstructure and one second microstructure of reference are integrated. The first microstructure and the second microstructure are arranged in the body so as to undergo equal strains as a result of thermal expansions of the body. Furthermore, the first microstructure is provided with movable parts and fixed parts with respect to the body, while the second microstructure has a shape that is substantially symmetrical to the first microstructure but is fixed with respect to the body. By subtracting the changes in electrical characteristics of the second microstructure from those of the first, variations in electrical characteristics of the first microstructure caused by thermal expansion can be compensated for.

摘要： The variable capacitance (1) according to the invention is based on a novel principle: a dielectric fluid (20) is placed in the air gap constituted by two capacitor electrodes (12, 14), the fluid being able to be displaced in a direction and outside the cavity (10) formed between said two electrodes (12, 14). Advantageously, the dielectric fluid (20) is displaced according to the principle of communicating vessels, with the presence of a second cavity (30) in fluidic relation with the first cavity. Actuation electrodes (46, 48) in the second cavity (30) induce the deflection of a membrane (44) in order to modify the relative heights of fluidic liquid in the two cavities (10, 30).

摘要： A chassis panel for a computerized device includes ventilation elements that visually obscure electronic components disposed within an associated chassis and that minimize airflow resistance. Each ventilation element includes a first angled ventilation portion having openings that provides limited visual access to the electronic components disposed within the chassis. Each ventilation element also includes a second angled ventilation portion having openings that provide no visual access to the electronic components disposed within the chassis. As such, the ventilation elements visually obscure the electronic components disposed within the chassis without the need for additional materials such as screens, mesh, or foam. Also, the openings of the first and second ventilation portions provide the chassis panel with a relatively large free area ratio, such as between about 42% and 48% or greater depending on hole pitch values and opening sizes. As such, the ventilation elements help to maximize air flow through the chassis to allow cooling of the electronic components disposed therein.
摘要翻译： 用于计算机化设备的底盘面板包括视觉上模糊设置在相关联的底盘内的电子部件并且使气流阻力最小化的通风元件。 每个通风元件包括具有开口的第一成角度的通风部分，其提供对设置在底盘内的电子部件的有限的可视通路。 每个通风元件还包括具有开口的第二成角度通风部分，该开口不提供设置在底盘内的电子部件的可视通路。 因此，通风元件在视觉上掩盖了设置在底盘内的电子部件，而不需要诸如屏幕，网眼或泡沫的附加材料。 此外，第一和第二通风部分的开口根据孔间距值和开口尺寸，使底盘面板具有相对较大的自由面积比，例如约42％至48％或更大。 因此，通风元件有助于使通过底盘的空气流最大化，以允许冷却设置在其中的电子部件。

摘要： The disclosure describes a variable capacitor device, which is formed by a linear motor and a variable capacitor having at least one stator electrode and a movable electrode. A piezoelectric transducer of the linear motor is frictionally coupled to the movable electrode. Application of electrical signals to the piezoelectric transducer of the linear motor produces a motion of the surface of the piezoelectric transducer. The frictional coupling between the piezoelectric transducer surface and the movable electrode transmits a fraction of piezoelectric transducer motion to the movable piston electrode thereby changing the capacity of the variable capacitor. The amount and sign of the capacitance change is selectable by the operator through control of the electrical signals applied to the piezoelectric transducer.
