Abstract: The present invention provides a method and apparatus for amplifying a nucleic acid sequence by polymerase chain reaction (PCR). The method comprises placing a PCR sample in a container which is heated by only a single heat source that provides a high temperature for denaturation in the bottom of the PCR sample, while annealing and extension automatically occur in different regions of the PCR sample due to the convection induced by a temperature gradient descending from the bottom of the PCR sample to the surface of the PCR sample.

Abstract: A liquid crystal display device includes a noise-receiving module for receiving external noise signals, a liquid crystal display module, and a frequency-switching means for switching scanning frequencies of the liquid crystal display module according to frequencies of the noise signals received by the noise-receiving module.

Abstract: An electrostatic discharge (ESD) protection apparatus for programmable device is provided. This ESD protection device provides a high impedance along the electrical path from the pad to the power system for preventing the programmable device from damages induced by ESD event; and the impedance can be intentionally decreased during the normal reading and writing operations.

Abstract: A multiple-time programming apparatus and method using one-time programming (OTP) elements are provided. The apparatus comprises a first adjusting OTP element, a second adjusting OTP element and a calculation device. An adjusting data is written into the first adjusting OTP element. When a modification in an IC is desired, the difference between a desired data and the prior adjusting data is written into the second adjusting OTP element. The calculation device adds the first OTP signal outputted from the first adjusting OTP element and the second OTP signal outputted from second adjusting OTP element, and outputs the resulting OTP signal with desired value. Thus, the apparatus and the method according to an embodiment of the present invention allow modification of data using the OTP elements that prevents from using expensive multiple-time programming elements.

Abstract: The present invention discloses a rotation apparatus of a dish antenna for adjusting a dish antenna to direct to a satellite. The rotation apparatus of the dish antenna includes an elevation bracket and a dish bracket. The elevation bracket includes two wings, a base and a cover, where the two wings are approximately parallel, the base connects the bottoms of the two wings and is approximately perpendicularly to them, and the cover is approximately perpendicularly connected to the front end of the base. The dish bracket includes a top plate and an arc plate, where the top plate includes at least one concentric groove, and the arc plate having at least one arc groove is approximately perpendicularly connected to top plate.

Abstract: A mouse interface converter is provided, which allows a mouse to be connectable to a computer system, such as a personal computer (PC), installed with either an RS-232 serial port or a PS/2 port. This mouse interface converter allows the mouse to be connected directly to PS/2 port and via an adapter to RS-232 serial port. The mouse interface converter includes a mode-detection circuit for detecting which type of port the mouse is currently being connected. The mode-detection circuit can generate a mode-indicating signal indicative of the type of the currently connected port, which is then used to set a control circuit to convert the mouse data to the corresponding format. The mouse interface converter further includes a driving circuit that allows the mouse to be more compatible with various signals of either the PS/2 port or the RS-232 serial port. This feature allows the mouse to be considerably reduced in power consumption that allows the mouse to be suitable for use on notebook computers.
