Abstract: It is disclosed that a mobile scanner includes only the minimum components to operate as a scanner. The disclosed scanner does not have a separate power supply to energize the components to work. Further, unlike many scanners in the market, there is not a single microcontroller in the disclosed mobile scanner while the performance thereof could outperform those scanners commanded traditionally by a microcontroller in the scanners. The disclosed scanner is coupled by an interface engine to a computing device that provides system control signals and power supply. The interface engine comprises a control circuit providing logic control signals to the scanner to operate in response to the system control signals. As such, the scanner is of high performance and low cost and so lightweight that it can be used in any conditions.

Abstract: Distinct designs are provided to reduce dimensions of an image sensing module without affecting the sizes of the original individual components in the image sensing module. According to one embodiment, a mirror is mounted before an optical focus system and used to collect and redirect reflected light from a scanning object being illuminated by an illumination source in the image sensing module, wherein the scanning object is parallel to the optical focus system.

Abstract: An image sensor employing multiple arrays of photodetectors is disclosed. According to one aspect of the present invention, every two of three arrays are shielded with a non-transparent material. When charge signals are generated in the non-shielded array in response to light reflected from a scanning document illuminated by one of three colored lights, the charge signals are shifted to a next adjacent shielded array so that another set of charge signals can be generated under another one of the three colored lights. Essentially, the shielded arrays are used as buffers to separate the charge signals independently generated under three different colored lights. Subsequently, the charge signals corresponding to the same colored light can be accumulated to produce a much stronger scanning signal.

Abstract: A banknote validation device includes a light source array which includes multiple light emission units; a light receiver configured to receive light emitting from the light emission units and to generate, upon receiving the light emitting from the light emission units, a detection signal corresponding thereto; a banknote channel arranged between the light source array and the light receiver; and a control circuit electrically connected to the light source array and the light receiver. The banknote channel is configured to receive a banknote to be validated to pass therethrough. The light receiver is arranged to correspond to multiple light emission units. The control circuit is configured to control the light emission units of the light source array to sequentially emit light according to a preset timing sequence of lighting. The present invention allows for inspection of a banknote to be validated with a simplified structure at the same accuracy.

Abstract: A method for automatically controlling the length of a projection screen and an apparatus thereof are proposed. They dispose a code stripe on at least a side of the projection screen and then exploit a detector of an auto-controlled hoister to read the code stripe. The detected signal is converted into digital data for comparison with the data stored in a storage device of the auto-controlled hoister so that the auto-controlled hoister can control the length of the projection screen exactly. Hence, a multi-purpose apparatus can be provided.

Abstract: A method and apparatus for providing images in 2-D scanners are disclosed. According to one aspect of the system, a series of images are successively generated from a sensing module in a scanner as the scanner is moving across a scanning document. A first image is initially kept in a memory. When a second image becomes available, an overlapping between the first image and the second image is located. From the overlapping, it is to determine if the stored first image is precisely registered with the second image. If the two images are registered, a signal-to-noise enhanced image is obtained by averaging the two images. If the two images are not registered, a combined image is obtained by combining the two images. Either the signal-to-noise enhanced image or the combined image is then stored in the memory to work with the next image. The process is repeated till all the images are processed. As a result, a signal-to-noise enhanced image or a combined image representing the entire document is produced.

Abstract: The disclosed architecture for an image sensor and the associated method employ an internal switching mechanism controlled by a much reduced number of shift registers to facilitate the readout of electronic signals generated by the photodetectors in the image sensor. The switching mechanism comprises resolution switches that can act sequentially or simultaneously so that image resolution can be controlled within the image sensor. Further, the overall performance of the image sensor is improved.
