Abstract: A testing method of a multiband antenna is provided. The testing method includes the following steps. Firstly, whether a testing angle of a multiband antenna is less than a default value is determined, and if the testing angle is less than a default value, then the testing frequency is set equal to a first default frequency according to the frequency table so as to obtain a first testing result corresponding to the first default frequency when the multiband antenna is at the testing angle. Next, whether the testing frequency needs to be changed is determined, and if the testing frequency needs to be changed, then the testing frequency is set equal to a second default frequency according to the frequency table so as to obtain a second testing result corresponding to the second default frequency when the multiband antenna is at the testing angle.

Abstract: An enhanced structure for the base with roller and belt of hardshell zipper case is provided, including a hardshell zipper case main body, a plurality of hidden roller units, a retractable belt unit, and an auxiliary wheel set. The hidden roller units and the retractable belt unit are placed inside the roller housing trench and the belt housing trench located at the bottom of the hardshell zipper case main body. When the hidden roller units are not in use, the roller units are entirely hidden inside the roller housing trench so that the roller unit will not be damaged due to careless handling. To move the hardshell zipper case, the outer rim of the roller units are exposed outside of the surface of the roller housing trench so that the roller units can roll along when moved. The belt of retractable belt unit can be easily pulled out from one end of the bottom of the hardshell zipper case.

Abstract: A method for detecting SECAM-L signals is disclosed. First, a SECAM-L signal is received and demodulated into a demodulation signal. Then high frequency components of the demodulation signal are filtered out and a low frequency signal, including many sync pulses and many data pulses, is obtained. Next, the low frequency signal is inversion into an inversion signal, having many inversion sync pulses and many inversion data pulses. Afterwards a voltage level of the inversion signal is detected continuously whether it is a lowest level. After that, the lowest level is determined whether belonging to the inversion sync pulses when the voltage level of the inversion signal is the lowest level, and a detection signal is outputted. When the lowest level belongs to the inversion sync pulses, a voltage level of the detection signal is high, and the demodulation signal is an inversion SECAM-L demodulation signal.

Abstract: Routing schemes are provided for a communication network. In one scheme, destination terminals and associated neighboring terminals are listed in a routing control cache at each communication terminal in the network, and packets are routed toward the destination terminal through the associated neighboring terminals. In another scheme, a single path from a source terminal to a destination terminal is automatically expanded into multiple paths. In yet another scheme, packets are routed as long as this does not increase the number of hops to the destination terminal. These schemes enable multiple paths to be established by a simple procedure not requiring complex distance calculations. In still another scheme, routing is restricted to the shortest path and paths up to a given number of hops longer than the shortest path, permitting paths to diverge in multiple directions from the source and destination terminals.

Abstract: In a wireless communication system, the communicating stations reduce their transmitting power level when they detect interference exceeding a certain level. Interference is detected by down-shifting the received signal to place the desired signal in the baseband, then sampling the down-shifted signal, first at a sampling frequency high enough to catch the interference, then at a lower sampling frequency that excludes the interference. This system is useful for vehicle-to-vehicle communication in an environment in which vehicle-to-roadside communication may also be present at various nearby frequencies, because it does not require exact knowledge of the interfering frequencies and allows communication to continue even when interference is present.

Abstract: An echo canceler uses an adaptive filter to remove an echo of a far-end input signal from a near-end input signal. Filter coefficients are calculated and updated while the far-end signal is active. While the far-end signal is silent, substitute filter coefficients are similarly calculated to be swapped in as initial values for the filter coefficients when the far-end signal changes from silent to active. The substitute filter coefficients are generated from a simulated far-end signal and a simulated near-end signal obtained by combining corresponding samples in different intervals of the far-end and near-end input signals. To facilitate convergence of the substitute filter coefficients, use of the simulated far-end and near-end signals is disabled when the corresponding samples cancel out.

Abstract: Disclosed is a method of manufacturing a semiconductor device that does not have a defect, such as wire breakage, due to an uplifted portion created at a rewiring pattern in a multilayer wire structure. Before a wiring layer is formed on an insulation layer, the insulation layer is exposed via a mask. The mask has a weak exposure part and a strong exposure part. The mask is positioned such that the weak exposure part corresponds to an arrangement position of a wire line of an underlying wiring layer, and such that the strong exposure part corresponds to an arrangement position of a via part of the underlying wiring layer. The underlying wiring layer is a layer immediately below the insulation layer.
