Abstract: The present invention relates to a circuit and a method for improving operation life of original various internal or external nonvolatile memories by means of long-life nonvolatile memory chips. In the case that the hardware structure, interface type, packaged type and operation condition of existing various nonvolatile memories are not changed yet, only long-life nonvolatile memory chips are added into original hardware structure, and correspondingly, long-life nonvolatile memory addresses are added into original memory addresses in main boot-block for the memories, the original device driver or operating system is modified, so as to increase operation life of the memories greatly.

Abstract: A noise-suppressing receiver is provided. A noise pick-up and a receiver are fixed within a cylinder-like body. An insulation layer is set between the noise pick-up and the receiver. The insulation layer divides the cylinder-like body into a receiver module and a noise-collecting module. A reticulate cover is provided at an end of the cylinder-like body, and a front cap is provided on the other end. A circuit device is added onto the inner side of the front cap described above. The invention has the stronger capability of attenuating environmental noise and the good effect of suppressing noise, because of its unique structure and the corresponding circuit device.

Abstract: An individual-type or combined-type of high performance noise-canceling pickup with front and rear sound inlets that are roughly toward the same direction or perpendicular to each other is provided to be composed of a plurality of noise-canceling sensors. The noise-canceling performance of that pickup is much better than that of only individual-type noise canceling pickup with the sound inlets on the front wall of the front cover and the rear wall of the rear cover. Even in the extremely bad circumstances of high volume of noise, high signal/noise ratio can be still maintained so that voice is distinct.

Abstract: An automobile alarm system includes: (1) a face identification and discrimination system, which consists of low-light, visible light, infrared light, and thermo-luminescence camera and/or digital camera device for photograph of inside and outside of automobiles, and face identification and discrimination hardware and software system for testing whether a mask or facial adornments or whether his/her face is directed at the camera; (2) redundancy device and/or redundancy function modules, anti-interference system for communication and anti-destructive detection system; (3) a automobile status recorder, which can record the statuses on the inside and outside of the automobile before, during and after an emergent event picked up by the camera; (4) a multi-functional burglar, anti-destructive and anti-hijacking alarm for automobiles, which can transmit a radio image to a remote equipment for reporting an incident. This invention can also be used for every supervision systems.

Abstract: A noise canceling pickup with an electret is provided with a cylinder body having a front cover and a rear cover, said front cover is provided with sound passing holes, said cylinder body is provided with an oscillating membrane of the electret, a back electrode sheet and a back electrode base, wherein said cylinder body is composed of a front cylinder body and a rear cylinder body, said oscillating membrane is provided into said front cylinder body, said rear cover of said cylinder body is provided with at least one sound passing hole, and said rear cover is provided with electric elements therein. With the arrangement according to the present invention, the distance between the opposite front and rear sound passing holes can be made smaller. The noise canceling pickup with an electret, can be used in the higher frequency band and in a wide frequency range to cancel the noises more effectively.
