An alarm method and system reduces costs, and the alarm method includes obtaining a detection signal from a terminal device, where the detection signal is a signal sent by the terminal device when the terminal device detects whether there is an available network, and performing an alarm operation when the detection signal meets a first condition.

Anti-theft method and apparatus

An anti-theft method and apparatus relating to the field of anti-theft technologies, and to reduce costs. The anti-theft method includes obtaining a detection signal from a terminal device, where the detection signal is a signal sent by the terminal device when the terminal device detects an available network, and performs an alarm operation when the detection signal meets a preset condition. The anti-theft method may be applied in daily life in order to ensure family property security.

Disclosed is a method of oxidizing a cycloalkane to form a product mixture containing a corresponding alcohol and ketone, said method comprising contacting a cycloalkane with a hydroperoxide in the presence of a catalytic effective amount of a crystalline MWW-type titanosilicate catalyst. Hydroperoxides may notably be tert-butyl hydroperoxide, tert-amyl hydroperoxide, cumene hydroperoxide, ethylbenzene hydroperoxide, cyclohexyl hydroperoxide, methylcyclohexyl hydroperoxide, tetralin hydroperoxide, isobutylbenzene hydroperoxide, and ethylnaphthalene hydroperoxide.

A parasitic lateral PNP transistor is disclosed, in which, an N-type implanted region formed in each of two adjacent active regions forms a base region; a P-type doped polysilicon pseudo buried layer located under a shallow trench field oxide region between the two active regions serves as an emitter; and a P-type doped polysilicon pseudo buried layer located under each of the shallow trench field oxide regions on the outer side of the active regions serves as a collector region. The transistor has a C-B-E-B-C structure which alters the current path in the base region to a straight line, which can improve the current amplification capacity of the transistor and thus leads to a significant improvement of its current gain and frequency characteristics, and is further capable of reducing the area and increasing current intensity of the transistor. A manufacturing method of the parasitic lateral PNP transistor is also disclosed.

A method of filling shallow trenches is disclosed. The method includes: successively forming a first oxide layer and a second oxide layer over the surface of a silicon substrate where shallow trenches are formed in; etching the second oxide layer to form inner sidewalls with an etchant which has a high etching selectivity ratio of the second oxide layer to the first oxide layer; growing a high-quality pad oxide layer by thermal oxidation after the inner sidewalls are removed; and filling the trenches with an isolation dielectric material. By using this method, the risk of occurrence of junction spiking and electrical leakage during a subsequent process of forming a metal silicide can be reduced.
