A method for integrating an IC and a MEMS component includes the following steps: S1) providing a SOI base (20) having a first area (21) and a second area (22); S2) fabricating an IC on the first area through a standard semiconductor process, and simultaneously forming a metal conductive layer (26) and a medium insulation layer (25c) extending to the second area; S3) partly removing the medium insulation layer and then further partly removing the silicon component layer so as to form a backplate diagram; S4) depositing a sacrificial layer (32) above the SOI base; S5) forming a Poly Sil-xGex film (33) on the sacrificial layer; S6) forming a back cavity (34); and S7) eroding the sacrificial layer to form a chamber (36) in communication with the back cavity. Besides, a chip (10) fabricated by the above method is also disclosed.

A monolithic triaxial gyro includes a mass block, a number of electrode groups and a drive comb group. The mass block includes main masses and a coupling mass coupled with the main masses. The main masses are positioned on opposite sides of the coupling mass and are symmetrical with each other along a Y-axis. The electrode groups include a first electrode group within an orthographic projection of the mass block, a second electrode group within an orthographic projection of the coupling mass and a third electrode group including a group of immovable slender flat plates and a group of movable slender flat plates. The drive comb group is connected to the main masses for driving movement of the main masses when signals are inputted into the drive comb group.

Discriminative pretraining technique embodiments are presented that pretrain the hidden layers of a Deep Neural Network (DNN). In general, a one-hidden-layer neural network is trained first using labels discriminatively with error back-propagation (BP). Then, after discarding an output layer in the previous one-hidden-layer neural network, another randomly initialized hidden layer is added on top of the previously trained hidden layer along with a new output layer that represents the targets for classification or recognition. The resulting multiple-hidden-layer DNN is then discriminatively trained using the same strategy, and so on until the desired number of hidden layers is reached. This produces a pretrained DNN. The discriminative pretraining technique embodiments have the advantage of bringing the DNN layer weights close to a good local optimum, while still leaving them in a range with a high gradient so that they can be fine-tuned effectively.

A siphon drainage type rainfall remote measurement device with self-compensation function is provided. The bottom existence of a rain collection barrel (2) is connected via a flexible tube (14) to the bottom of a rainfall measuring tube (13) to which a siphon (5) is attached. The tube (13) and a measurement instrument (6) are installed on a holding frame (9). The instrument (6) is connected to a pressure sensor (12) and an accumulator (11) at the bottom of the tube (13). The whole device is fixed in an outer barrel (1). According to the pressure of the bottom of the tube (13), the sensor (12) measures the height of the water level in the tube (13) which is directly proportional to the rainfall. The sensor (12) signal processed by the instrument (6) is transformed into the rainfall, processed by a compensation algorithm and sent by GSM or GPRS.

A cooling device includes an inner sleeve with an outer surface, an outer sleeve surrounding the inner sleeve, and two end portions extending between the inner sleeve and the outer sleeve at the ends. The inner sleeve, the outer sleeve and the end portions define a peripheral space. A flow guiding structure defines N channels in the peripheral space for coolant to flow, where N is an integer equal to or greater than 1. Each channel has at least two branches, and N pairs of inlet and outlet corresponding to the N channels. The branches of each channel are in fluid communication with a respective pair of inlet and outlet. Each branch extends over a half circumferential part of the outer surface of the inner sleeve. An electric motor incorporating the cooling device is also provided.

An electric motor, especially a brushless PMDC motor, has a stator and a rotor rotatably installed inside of the stator. The stator has a housing with an open end, an end cap fixed to the open end of the housing, a stator core fixed to an inner surface of the housing, and windings wound on the stator core. The rotor includes a plurality of permanent magnetic poles. The housing has a flange bent inwardly from the open end of the housing and abutting against the end cap inwardly and axially to thereby fix the end cap to the housing. The length of the flange measured along the circumferential direction of the housing is greater than half of that of the housing.

A method for reconstructing three-dimensional, plural views of images from two dimensional image data. The method includes: obtaining two-dimensional, stereo digital data from images of an object; processing the digital data to generate an initial three-dimensional candidate of the object, such process using projective geometric constraints imposed on edge points of the object; refining the initial candidate comprising examining spatial coherency of neighboring edge points along a surface of the candidate.

摘要:
A method for manufacturing a MEMS sensor and a thin film thereof includes steps of etching a top surface of a single-crystal silicon wafer in combination of a deposition process, an isotropic DRIE process, a wet etching process and a back etching process in order to form a pressure-sensitive single-crystal silicon film, a cantilever beam, a mass block, a front chamber, a back chamber and trenches connecting the front and the back chambers. The single-crystal silicon film is prevented from etching so that the thickness thereof can be well controlled. The method of the present invention can be used to replace the traditional method which forms the back chamber and the pressure-sensitive single-crystal silicon film from the bottom surface of the silicon wafer.
