20090167530 | REMOTE PUBLIC FULL-TIME ANTI-THEFT SYSTEM - The invention relates to a remote anti-theft alarm system comprising a plurality of mechanical switches for collecting moving signals of protected objects, a plurality of self-induced infrared sensors for collecting signals of relative movements between protected objects and adjacent objects and a spot detecting-and-alarming circuit, wherein the mechanical switches and the self-induced infrared sensors connect in the spot detecting-and-alarming circuit which communicates with a remote supervision center through a public data communication network. This system is excellent in anti-theft effects and difficult to be damaged by a thief, especially suitable for anti-theft of valuables in public. | 07-02-2009 |
20090167523 | SELF-POSITIONING REMOTE BURGLARY ALARM SYSTEM - The invention relates to a self-positioning remote burglary alarm system comprising a plurality of sensors used for collecting signals related to burglary, a signal collecting and converting circuit used for receiving and converting signals collected by the sensors, a GPS signal receiving module used for getting a real-time geographical location coordinates information, a microcomputer used for generating alarm information codes, a communication module, a modem and a mobile phone. The invention sends alarm information to a control center or relevant personnel when collecting signals related to burglary. | 07-02-2009 |
20090166413 | ENTRANCE GUARD SYSTEM USING ARBITRARY CARD - This invention relates an entrance guard system using arbitrary card comprising one or more card readers for entrance guard controlling, one or more entrance guard controllers, a CPU and one or more guest information input devices, wherein each of the guest information input device includes a guest information reader, a entrance card writing device and a manual input device used for inputting an instruction of registering guest information to the CPU. The CPU acquires the card information captured by a said guest information reader and stores the card information and other guest information in a guest information database as the guest's identification information. This system can use an arbitrary electron card as entrance card. | 07-02-2009 |
20090166410 | MULTIFUNCTION ATTENDANCE CHECKING SYSTEM - This invention relates to a multifunction attendance checking system comprising a card reader for card-making, said system using the information acquired from an existed card of a user by the card reader for card-making as the user's identification information and using the existed card as a timecard of the user, further comprising a microprocessor, one or more card readers for attendance checking and a memorizer. This system allows an existed card of a user as a timecard. | 07-02-2009 |
20090166160 | MULTI-LEVEL MICRO-SWITCH - The present invention relates to a multi-level micro-switch comprising a housing and a fixed supporting cylinder disposed in the center of the housing and extending upwards along the axis of the housing, wherein a plurality of multi-level supporting cylinders are sequentially and flexibly contained in the fixed supporting cylinder. The bottom of the fixed supporting cylinder is connected to the housing and a plurality of beams is constantly arranged around the fixed supporting cylinder. A slide ring is arranged on the inner side of the housing which fits with the vacancy of the housing. An inner casing is contained in and flexibly connected to the housing, touching the slide ring at the bottom end, and a conductive ball is disposed in the vacancy above the beams. The invention may choose different thresholds of detection sensitivity for each application and be typically utilized as a movement-detection unit in an electronic surveillance system, especially an anti-theft system. | 07-02-2009 |
