Abstract:
The invention provides a three-party video conference system and method. The three-party video conference system, according to the invention, uses a second terminal apparatus, which can transmit data in different protocols for receiving and transmitting the compressed digital signals transmitted from a first terminal apparatus and a third terminal apparatus. Therefore, even though the first terminal apparatus and the third terminal apparatus can not transmit compressed digital signals to each other with the same protocol, the user still can achieve three-party video conferencing communication with the three-party video conference system.
Abstract:
The invention discloses a cursor control method applied to a presentation system. The presentation system comprises a computer, an imaging plane, an optical pointer, a camera, and a projector. The projector is a mobile or built-in projector of the computer for projecting output from the computer onto the imaging plane, wherein the output of the computer comprises an internal cursor generated by the computer. The optical pointer is used for projecting an external cursor onto the imaging plane. The camera is a mobile or built-in camera of the computer for capturing an image of the imaging plane. After capturing the image, a processor of the computer detects both a first position of the external cursor and a second position of the internal cursor corresponding to the image, calculates a shift vector between the first and second positions, and moves the internal cursor based on the shift vector.
Abstract:
A mobile phone can include an application processor and a baseband processor. The application processor has a first file system and the baseband processor has a second file system. The baseband processor is connected to a host interface unit of the application processor via a memory bus. The baseband processor can set registers and FIFO queues of the host interface unit and thereby control the application processor to achieve the goal of exchanging information. The invention provides a bridging file system for bridging the file systems in the two processors. Thus, the first file system of the application processor can access files in the second file system of the baseband processor.
Abstract:
The invention discloses an apparatus for increasing the display gray levels. The apparatus includes a signal transformation circuit, an error diffusion circuit, and an operation circuit. According to a first predetermined manner, the signal transformation circuit transforms a set of image signals into a set of transformed signals. The error diffusion circuit receives the set of transformed signals and generates a set of diffused signals according to a judging rule. The operation circuit receives the set of diffused signals and generates a set of output image signals according to a second predetermined manner and a predetermined operational rule.
Abstract:
This invention discloses a transforming apparatus, according to a transforming curve, for transforming a first image to a second image. The first image includes a plurality of pixels. The transforming apparatus includes a differentiating module, a first transforming module, an adjusting module and a second transforming module. According a predetermined value, the differentiating module transforms the transforming curve into a plurality of sub-curves. The first transforming module generates a plurality of straight lines corresponding to the sub-curves. According to the sub-curves, the straight lines and a predetermined threshold, the adjusting module adjusts the straight lines to generate a plurality of approximate lines. According to the approximate lines and the pixels of the first image, the second transforming module generates the second image.
Abstract:
A multi-state recognition device of a server blade system is provided. The multi-state recognition device comprises a logic circuit set for receiving a system state signal to control a multi-color LED set, and the multi-color LED set which illustrates the current sate of the blade server. The multi-state recognition device of the blade server receives plural signals outputted by the blade server and plural signals outputted by the system management unit. The blade server, the system management unit, and the multi-state recognition device all receive a main power source signal. The multi-state recognition device comprises a logic circuit set and a multi-color LED set, wherein the logic circuit set controls the multi-color LED set according to the plural signals outputted by the blade server and the plural signals outputted by the system management unit, so that the multi-color LED set generates various light signal states.
Abstract:
An auto-extending replicator includes a replicator body, a forcing mechanism, an extended unit and a control mechanism. The extended unit includes an extended body and a blocking member. The forcing mechanism connected between the replicator body and the extended body exerts a force on the extended body along a direction of extending. The blocking member connected with the extended body has a stepped structure. A control mechanism second end blocks the blocking member from extending out. When a control mechanism first end is displaced, a contact position between the blocking member and the control mechanism second end is changed so that the extended body together with the blocking member move extendedly along the direction of extending.
