Abstract: A circularly polarized antenna includes first and second dielectric substrates, a grounding element, a feeding element, a coupling element, and a close-loop radiating element. The grounding element is formed on a first surface of the first dielectric substrate. The feeding element is formed on a second surface of the first dielectric substrate. The second dielectric substrate is disposed on the second surface of the first dielectric substrate and overlaps the feeding element. The coupling element is formed on the second dielectric substrate. The close-loop radiating element is formed on the second dielectric substrate.

Abstract: A method of manufacturing an array substrate of a transflective liquid crystal display is provided. Utilizing backward exposure and half-tone photo-mask to reduce the number of photo-masks used in the manufacturing process, only three to four photo-masks are used to manufacture a transflective liquid crystal display.

Abstract: The present invention provides a detachable data input device for use with a portable electronic apparatus. The data input device such as a keyboard includes a connecting device, a housing, and an adjustment unit. The connecting device includes at least one projection and a first slot. The housing has a second slot and an angle is formed between the extending directions of the first slot and the second slot. The adjustment unit is movable between a first end and a second end of the second slot and is pivotally connected to the connecting device by passing through the first slot and the second slot. When the adjustment unit moves to the first end, the projection extends out of the housing by a first length. When the adjustment unit moves to the second end, the projection extends out of the housing by a second length. The first length is different from the second length.

Abstract: The invention provides a photochromic dye of a structure containing a common structure of spirooxazine series compounds and three substituents. The photochromic dye according to the invention exhibits characteristics of a high heat stability, good light fatigue resistance, high sensitivity, extremely degradation rate and the like. This photochromic dye can be formulated with suitable organic solvents and used as photochromic functional colorants under UV light excitation. Further, this photochromic dye can be synthesized and purified in simple steps with cheap raw materials and hence at a greatly lowered production cost.

Abstract: A first compensation factor, a second compensation factor and a third compensation factor are provided to improve a capacitance-voltage (C-V) method for measuring an effective channel length of a metal-oxide-semiconductor field effect transistor (MOSFET), and an overlap length of a gate and a source and a drain of the transistor. The first compensation factor is calculated by measuring two unit length gate capacitances of the transistor. The second compensation factor is calculated by measuring two unit length overlap capacitances of the transistor. The third compensation factor is a ratio of the second compensation factor to the first compensation factor.

Abstract: An urgent power-supply arrangement using cascaded wireless mobile devices is provided. A first wireless mobile device has a load device and a battery device for supplying power to the load device. A second wireless mobile device is powered by a battery device. The second wireless mobile device is electrically connected to the first mobile device such that the battery device of the first wireless mobile device is cascaded with the battery device of the second wireless mobile device for supplying power to the load device of the first wireless mobile device.

Abstract: A pen type scanner (10) having an optically conductive light director (24) for directing light from a light emitting diode (20) onto a specific portion of textual data (78) on a page (76). Light reflected from the page is focused by a lens assembly (28) onto a sensor apparatus (30). As the pen type scanner (10) is moved across the page (76) a roller (34) activates a distance encoder (32). The pen type scanner (10) is connected to a parallel port (54) of a computer (56) through an interconnection cable (50) and a port adaptor component (58).
