The invention discloses an aluminum film baffle device and a pulse solid engine applying the same. The aluminum film baffle device takes a flexible aluminum film baffle as a fracture element and is matched with a hollow-carved baffle support in a cross-shaped supporting structure. The aluminum film baffle can bear high pressure and cannot be fractured in the direction where the aluminum film baffle is supported by the baffle support while the flexible aluminum film baffle can be fractured easily in the direction where the aluminum film baffle is not supported by the baffle support. One side of the aluminum baffle, which cannot be fractured, is dead against a first pulse grain so as to prevent the aluminum baffle from being fractured during the burning process of the first pulse grain of the engine. Therefore, a second pulse grain of the engine can be protected. When the second pulse grain is ignited, the aluminum film baffle rapidly is fractured so that gas passes through the aluminum film baffle device. The device provided by the invention has stable and reliable performance and the material of the baffle is easy to get and process. The fragments of the fractured aluminum film baffle can not affect the operation of the engine and the device has no special requirements on a loading device and an igniter.

The invention provides a non-contact differential type speed encoder, which is positioned on the outside of gear teeth of a speed measuring gear and comprises a magnetic element and hall elements, wherein the hall elements are arranged on / in a shell and symmetrically distributed, and two hall elements are symmetrically distributed. The hall elements output high levels when meeting a strong magnetic field and output low levels when meeting a weak magnetic field. The backs of the hall elements generate a magnetic field by using a permanent magnet. When gaps of the gear aim at the hall elements, magnetic lines of force are dispersed and the hall elements output the low levels; and when the teeth of the gear aim at the hall elements, magnetic lines of force are concentrated and the hall elements output the high levels. Thus, the higher the rotation speed of the gear is, the higher the frequency of output signals is. Then the rotation speed of a motor can be detected. Because the gear is not in contact with a detection element, the non-contact differential type speed encoder has no mechanical friction and has long service life; and because dust, water and the like do not affect work, the non-contact differential type speed encoder has strong adaptation to environment. In addition, because the gear can be arranged outside the motor, a hot environment in the motor is avoided.

Projection cloth with touch function and imaging touch system of projection cloth
InactiveCN102646001AImprove flexibilityEasy to hideProjectorsInput/output processes for data processingUltra fineIntegrated circuit
The invention discloses a piece of projection cloth with a touch function. The projection cloth comprises a base material, wherein the front surface of the base material is a touch operation surface; an imaging layer and a conducting wire layer which is used for sensing a touch signal are pasted and covered on the back surface of the base material in sequence; the imaging layer is an orthographic projection imaging layer or a back projection imaging layer; the conducting wire layer is a warp and weft net which is formed by winding and crosswise interlacing ultra-fine conducting wires along an X axis direction and a Y axis direction respectively, and the ultra-fine conducting wires are insulted with one another at the cross points; a space defined by each grid forms a sensing unit; and the output end of the conducting wire layer is connected with an induced signal acquisition control integrated circuit. The imaging touch system has an effect of projection imaging and the touch function, can effectively perform human-computer interaction while displaying information, and realizes real-time, convenience and high-efficiency of meetings, school-teaching and lectures.
