Abstract: A temperature indication pipe joint, including a shell, wherein a water conduit is arranged in said shell, and including a heat transmission unit which has a first end in said water conduit and a second end connected to the center of a spiral double sheet metal, said spiral double sheet metal further has an indicating needle extended from its other end. By utilizing the double sheet metal to sense the change of temperature and deform accordingly, the water temperature can be indicated, which can reduce the cost and achieve a simpler structure compared to the digital thermometer used before; when rotating the cover of the present invention, the quantity of water stream will be adjusted.

Abstract: A configuration structure of a spray nozzle and a shower head, adapted to a wall outlet, includes a three-way control valve, a connecting rod and a spray unit. The three-way control valve has an inlet connected to the wall outlet, a front outlet connected to an inlet tube extending from a rear side of the connecting rod, and a lower outlet connected to a hose of the spray unit. The connecting rod has a closed lower end, an upper end connected with the shower head, and at least one spray head at a front side thereof. With the three-way control valve and the connecting rod, the front and lower outlets of the three-way control valve are connected to the spray nozzle and the connecting rod respectively to form two water passages. The upper end of the connecting rod is connected with the shower head.

Abstract: A mounting structure of a spray nozzle and a shower head in conjunction with a wall outlet includes a three-way control valve, a connecting rod and a spray unit. The three-way control valve has an inlet connected to the wall outlet, an upper outlet connected to the shower head, and a lower outlet connected to the connecting rod. The connecting rod has a lower end connected with the spray unit and a lower part secured on a wall through a retaining bracket. The spray unit has a retaining seat movably coupled to the connecting rod for insertion of the spray nozzle. With the three-way control valve and the connecting rod, the upper and lower outlets of the three-way control valve are connected to the shower head and the connecting rod respectively to form two water passages. The lower end of the connecting rod is connected with the spray unit.

Abstract: An automatic valve includes a three-way valve body and a valve core disposed in the valve body. The valve core has a large flange and a small flange formed at middle and front sections, an axial hole therein, and a water outlet formed between the large and small flanges. The water outlet interconnects with the axial hole. The valve body has a front section connected with a connector. A retaining head is inserted into the connector to connect with the valve core. The small flange of the valve core is moved to seal the connector. The water flows into the axial hole, out from the water outlet of the valve core, and into the chambers of the valve body. The valve body may use one side port to connect with a feed pipe and the other side port and the lower port as outlets to connect with outlet devices.

Abstract: A combination heat sink form of a stack of radiation fins is disclosed. Each radiation fin has retaining flanges at two opposite lateral sides for securing another radiation fin. Each retaining flange has a bottom neck perpendicularly extending from the respective radiation fin, two pairs of vertically spaced retaining fingers respectively extending from two opposite lateral sides of the bottom neck in a parallel manner relative to the respective radiation fin for securing another radiation fin, a top retaining notch defined between the two pairs of vertically spaced retaining fingers above the bottom neck for accommodating the bottom neck of another radiation fin, and a retaining gap defined between each two vertically spaced retaining fingers for receiving another radiation fin.

Abstract: Techniques for an adaptive filter method are disclosed. According to one aspect of the techniques. According to one aspect of the present invention, an adaptive filter technique is disclosed.

Abstract: Techniques to enhance voice signals in a dual microphone system are disclosed. According to one aspect of the present invention, there are at least two microphones that are positioned in a pre-configured array. Two audio signals x1(k) and x2(k) are received and coupled to an adjusting module that is provided to control the gain of each of the audio signals x1(k) and x2(k) to minimize signal differences between the two signals. A separation module is provided to receive matched audio signals x?1(k) and x?2(k) from the adjusting module. The separation module separates the audio signals x?1(k) and x?2(k) to obtain a first audio signal s(k) containing mainly the voice and a second audio signal n(k) containing mainly the noise. An adaptive filtering module is provided to eliminate the noise component in the audio signal s(k) to obtain an estimated voice signal e_s(k) with a higher S/N ratio. Furthermore, the adaptive filtering module can be also configured to suppress echo in the audio signal s(k) at same time.
