  • Publication number: 20080278317
    Abstract: A real-time monitor system including at least one public facility, a second wireless transceiver, and a control center is provided. The public facility includes a power generator, a load, a signal generator, and a first wireless transceiver. An initial power provided by the power generator drives the load. The signal generator determines whether or not to output a condition signal and a positioning signal according to whether the load is driven. Then, the condition signal and the positioning signal are emitted to the second wireless transceiver by the first wireless transceiver. Therefore, the control center determines the service condition of the public facility according to the information of the condition signal or whether the condition signal is received, and determines the position of the public facility according to the positioning signal.

  • Patent number: 7002414
    Abstract: A digital adjustable chip oscillator comprises a voltage control oscillator, a reference voltage circuit, a voltage regulation circuit, a digital tuning circuit, a frequency detector and a programmable controller. The oscillator generates an oscillation signal and receives a control voltage and an operating voltage from the voltage regulation circuit and the reference voltage circuit to stabilize and adjust the frequency of oscillation signal. The digital tuning circuit receives a digital code stored in a programmable memory to adjust the control voltage. The frequency detector detects and compares the frequency of oscillation signal with a first and second frequency, wherein when the frequency of the oscillation signal lies between the first and second frequency, the frequency detector outputs a high voltage signal and otherwise the frequency detector outputs a low voltage signal. The programmable controller receives the high voltage signal to stop a programmable counter to acquire the digital code.

  • Patent number: 6704322
    Abstract: A smart different prime code multiplexing system. Using the characteristic that two different prime codes do not interfere with each other, these two prime codes are combined to replace the conventional asynchronous division multiple access. Without affecting the user and the original data, in the original optical fiber transmission system, other users or data are dynamically added to improve the insufficient capacity of the prime code system. The decoding capacity is thus raised to achieve the objective of multiple access. Furthermore, in the invention, a synchronous parallel prime code is used to increase the original asynchronous decoding capacity. Therefore, a decoding capacity in the asynchronous system similar to that of the synchronous system is obtained. Characteristics such as ultra-high capacity and ultra-high operating speed can also be achieved.
