Abstract: A combination of an optical module and a transmitting and carrying structure includes an optical module, at least one carrying seat, and two rollers. The at least one carrying seat is combined with the optical module, for mounting the two rollers. The two rollers are located at the two opposite sides of the optical module. The two opposite sides of the optical module are perpendicular to the movement direction of the optical module. Thus, the at least one carrying seat and the two rollers are used to support and transmit the optical module, so that the optical module may be well balanced. In addition, the assembly height and the cost of fabrication are reduced.

Abstract: A scanning module having an adjustable height includes a CIS module having two ends along a longitudinal direction each provided with a distance adjusting member. Thus, when the CIS module is scanning the reflective document and the transparency, the distance adjusting member may be adjusted to change the distance between the CIS module and the glass window for the to-be-scanned document to be placed on. Thus, under scanning of the CIS module, both of the reflective document and the transparency may obtain a clear image effect.

Abstract: A method for improving the use of a transmission spectrum in a multi-sector wireless communication system includes generating a first signal, processing a first signal with a first Auto Tune Combiner, transmitting the first signal on an antenna associated with a first sector, sampling the first signal with a radio frequency test device, generating a second signal, processing the second signal with a second Auto Tune Combiner, transmitting the second signal on an antenna associated with a second sector, and sampling the second signal with the radio frequency test device.

Abstract: An apparatus for improving the use of a transmission spectrum in a wireless communications system. The apparatus includes a first radio source for generating a first signal, a first Auto Tune Combiner for processing the first signal, a first antenna associated with a sector for transmitting the first signal, a first radio frequency test device for sampling the processed first signal and producing a first feedback signal, a second radio source for generating a second signal, a second Auto Tune Combiner for processing the second signal, a second antenna associated with the sector for transmitting the second signal, a second radio frequency test device for sampling the processed second signal and producing a second feedback signal, and a multicoupler for directing the first and second feedback signals to the first and second radio sources.

Abstract: A vibration reduction gear structure of an image input and output device includes a first gear supporting a second gear, and a vibration reduction portion made of vibration reduction material mounted on at least one of the first gear and the second gear. The other gear is rested on the vibration reduction portion. In such a manner, when the first gear and the second gear are rotated synchronously, the vibration between the first gear and the second gear may be reduced by the vibration reduction portion.

Abstract: 7A modular scanner has a housing with a transparent platform upon which a document may be placed. A first control board for controlling operations of the scanner is disposed within the housing. A scanning module is also installed inside the housing and is electrically connected to the first control board. The scanning module is used to scan a document placed on the transparent platform to generate corresponding image data. A first input device is disposed on the housing to provide an input interface. The first control board is removably installed inside the housing, and the first input device is removably connected to the housing. The first control board and the first input device are capable of being replaced, respectively, with a second control board and a second input device.

Abstract: A bushing assembly having a self-alignment function includes inner bushings mounted in outer bushings. A center adjustment unit is mounted between the outer bushing and the inner bushing, and includes convex arcuate faces mating with concave arcuate faces. Thus, the inner bushing may micro-adjust an assembly angle automatically, to maintain at the same axis with other inner bushing, thereby facilitating passage and mounting of a shaft. In addition, the outer bushing or the inner bushing is formed with a slit, or the outer bushing may be made detachable, so that the outer bushing and the inner bushing may be combined easily.

Abstract: A transparency scanning mechanism of a CIS scanner for scanning a transparency includes a plane light source mounted on the upper cover of the scanner, for projecting the transparency. A guide device is mounted on the upper cover and located adjacent to the plane light source for guiding the transparency to face the plane light source. Thus, the CIS scanner may be used to scan the transparency. The scanning mechanism and the upper cover may be made integrally, thereby decreasing cost of fabrication. In addition, the upper cover may be provided with a driving device and/or a retaining device adjacent to the guide device, to mate with movement of the transparency, so that the transparency may be moved conveniently, thereby preventing the transparency from being tilted and deviated.
