摘要： A millimeter-scale pulse jet engine comprises an engine body that defines a combustion chamber, a fuel, an air intake, and an exhaust. The fuel inlet is arranged to inject fuel directly into the combustion chamber. The air intake and the exhaust are in fluid communication with the combustion chamber, and the combustion chamber is configured such that air from the air intake and fuel from the fuel inlet cyclically combust in the combustion chamber to produce exhaust gases.

摘要： In order to discriminate between laminar flow and turbulent flow states, and to provide an indication, e.g. to a pilot of an aircraft of air flow over an aircraft wing, a sensor mounted on the wing provides an analogue signal of airflow, and an intermittency value of the analogue signal is derived in analogue circuitry including an AC coupling of the signal to an integrator for integrating the signal for a preset time. The integrated value is compared with a threshold value to indicate whether the intermittency represents quiet laminar flow or noisy turbulent flow.

摘要： To provide an indication of whether airflow is separated, as opposed to other states of flow, over a surface, two or more adjacent sensors at a location on the surface each produce an analogue signal representative of airflow. The analogue signals are correlated with each other, and the degree of correlation indicates whether the airflow is in a separated state. The correlation may be carried out by comparing processed values of the analogue signals, and thresholding the comparison result.
摘要翻译： 为了提供气流与表面上的其它流动状态相对应的指示，表面上的位置处的两个或更多个相邻传感器产生代表气流的模拟信号。 模拟信号彼此相关，并且相关程度指示气流是否处于分离状态。 可以通过比较模拟信号的处理值和阈值比较结果来执行相关性。

摘要： A sensor device for sensing air flow speed at the exterior of an aircraft, comprising a substrate having an upper side on which is mounted a diaphragm over an aperture or recess in the substrate, the diaphragm being thermally and electrically insulative, and mounting on its upper surface a heating element comprising a layer of resistive material, and wherein electrical connections to the heating element are buried in the diaphragm and/or the substrate, and provide electrical terminals at the lower side of the substrate. The heating element is exposed to the environment, but the remaining electrical parts of the device are not exposed.

摘要： A bonding tool and method A bonding tool and method for bonding together layers of a MEMS transducer device, including at least one layer of a piezoelectric material, and an intermediate reinforcing layer of titanium, or other metal, comprising: positioning the layers above one another and spaced apart by means of spacing members, heating said layers to a bonding temperature, and retracting the spacing members so as to bring the layers together under pressure to effect a bond between adjacent surfaces of the layers, wherein a press head is employed with a compliant caul for evenly distributing the press force; and permitting said layers to cool to an operating temperature in which said piezoelectric layer is under compressive strain and the titanium layer is under tensile strain.
