| 20100171526 | PHASE-DISCRIMINATING DEVICE AND METHOD - A high-accuracy and computational efficient phase-discriminating device is provided and includes a phase-discriminating unit. The phase-discriminating unit converts an input and a reference signals into an input and a reference sequences respectively by a one-bit A/D conversion operation, determines a first value, an in-phase component and a quadrature component of the input signal in response to the input and the reference sequences, and produces an estimated phase of the input signal according to a relation among the first value, the in-phase component and a polarity of the quadrature component, wherein the first value is a certain integer being one of a first integer and a second integer, the first integer is a sampling count of the one-bit A/D conversion operation for producing the input sequence, and the second integer is a summation of an absolute value of the in-phase component and that of the quadrature component. | 07-08-2010 |
| 20100235708 | WIRELESS COMMUNICATION METHOD, INFORMATION ACCESS METHOD, AND VIRTUAL ANTENNA RADIATION PATTERN FORMING METHOD - A wireless communication method for transmitting information to the designated region with the boundary defined by the sharp cutoff is provided. Receivers outside the designated region are excluded from retrieving the encoded information. The boundary of designated region is adjustable. The wireless communication method can be applied to clearly defining the accepted region and rejection region in satellite communications. The wireless communication method includes steps of providing an information; encoding the information into an encoded data regarding a designated bit-energy-to-noise-ratio; transmitting the encoded data to form a virtual antenna radiation pattern covering a designated region with boundary defined by the sharp cutoff based on the designated bit-energy-to-noise-ratio; receiving the encoded data; and decoding the encoded data into the original information only when receivers within the designated region with bit-energy-to-noise-ratio no less than the designated bit-energy-to-noise-ratio. The critical feature of the method is clarified by experiments on the communication satellite ST-1. | 09-16-2010 |

| 20090103248 | Solid electrolytic capacitor - An electrolytic capacitor has at least one capacitor element and an insulating housing. Each capacitor element has a body and at least two leads. The leads connect to the body. The insulating housing has a base. The base has a top with at least one opening, a bottom, at least two holes and at least one chamber. The opening is sealed after the at least one capacitor element is mounted in the base. The holes are defined through the bottom and allow the leads to extend out and to be fastened with sealant. The chamber is formed in the base, communicates with the opening and the holes and receives the capacitor element. Because the electrolytic capacitor is simple, the electrolytic capacitor is assembled easily and quickly to lower cost. Further, the insulating housing is able to hold multiple capacitor elements, so the solid electrolytic capacitor has an increased capacitance. | 04-23-2009 |
| 20100296228 | Electrolytic capacitor - The electrolytic capacitor has an insulating casing, at least one capacitor element and multiple external terminals. The casing has multiple through holes and mounting protrusions. The at least one capacitor element is mounted in the casing and has multiple inner conductive pins connecting to a coil. Each external terminal is attached to a bottom panel of the insulating casing, connects to a corresponding inner conductive pin and has a main body, a connecting portion and two fixing portions. The connecting portion is formed on and extends from a side of the main body and has a conducting hole attached to a corresponding conductive pin. The fixing portions respectively extend from two ends of the main body and engage with the mounting protrusions. Each external terminal provides a soldering surface being flat and having large soldering area, therefore the electrolytic capacitor can be firmly soldered on a circuit board. | 11-25-2010 |
