Abstract: In an intelligent monitoring system, a wireless signal processing device transmits a wireless signal toward a first target object in a monitored area, receives a wireless status signal, and generates a monitoring signal corresponding to the first target object according to the wireless status signal. In addition, at least one signal-relaying device receives a back scattering signal, which is reflected from the first target object in response to the wireless signal, transfers the back scattering signal into the wireless status signal, and transmits the wireless status signal to the wireless signal processing device. The signal-relaying device includes a power supply device for supplying power for operations of the signal-relaying device, and the signal-relaying device is disposed in the monitored area between the first target object and the wireless signal processing device.

Abstract: A characteristic impedance of an electric transmission line is measured by way of extraction. In the method, a first probe and a second probe are provided, wherein the first probe and the second probe are separable and independently operable probes. A first characteristic impedance of a first circuit where a first terminal of the first probe and a first terminal of the second probe are directly interconnected to each other is first measured. Then a second characteristic impedance of a second circuit where the first terminal of the first probe and the first terminal of the second probe are connected to opposite terminals of the electric transmission line, respectively, is measured. The characteristic impedance of the electric transmission line can then be obtained according to the first characteristic impedance and the second characteristic impedance.

Abstract: An interlaced array antenna includes first and second groups of antenna units, which are of the same size in the same group and different sizes in different groups. Each antenna unit is polygon-shaped with even-numbered edges, and has feed-in terminal and coupling terminal at two corners. A preceding one and a succeeding one of the antenna units included in the first group are interconnected via a specified one of the antenna units in the second group. An input signal is transmitted through the feed-in terminal and then the coupling terminal of the preceding antenna unit, the feed-in terminal and then the coupling terminal of the specified antenna unit, and the feed-in terminal and then the coupling terminal of the succeeding antenna unit in sequence. Configurations of adjacent two antenna units in the same group are identical once one of them is flipped about the x-axis.
