Abstract: A system for management of SMT stencils includes: a plurality of controllers (5), each of which is connected to a sensor (7) for generating a signal when a piece of PCB is passing through an SMT machine (4) on which an SMT stencil is mounted and for adding one to each of current cumulative operation times and current continuous operation times of the stencil; and a server (1) including: a data obtaining module (12) for obtaining signals from the controllers; a parameter setting module (13) for presetting parameters of each stencil; an analyzing module (14) for obtaining the current cumulative operation times and current continuous operation times of the stencil; and a determining module (15) for determining a usage condition of the stencil by comparing the current cumulative operation times and current continuous operation times with respective preset parameters, and generating different messages according to different usage conditions of the stencil. A related method is also disclosed.

Abstract: A procedure downloading system includes a web server (2), a database server (1), a video server (6), and monitor computers (5) linking to the web server through a communication means (4). The web server includes: an IP (Internet Protocol) address obtaining module (22) for obtaining IP addresses from said monitor computers; an IP address determination module (23) for determining whether an obtained IP address is already in the database server; a download request receiving module (24) for receiving a procedure download request from a monitor computer if the obtained IP address is not in the database server; a procedure downloading module (25) for downloading a communication procedure to the monitor computer according to the received procedure download request; and a procedure installing module (26) for installing the downloaded communication procedure in the monitor computer. A related procedure downloading method is also disclosed.

Abstract: A system for remotely controlling cameras includes an application server (3), a database (5), and a plurality of client computers (1). The application server includes: a connecting module (31) for connecting a corresponding camera to the application server; a camera controlling module (32) for controlling and adjusting the cameras to obtain clearer signals; a video signal collecting module (33) for collecting video signals; a video signal compiling module (34) for compiling the video signals into video data that can be viewed by users; and a data transmitting module (35) for transmitting the video data to the client computers. A related method for remotely controlling cameras is also disclosed.

Abstract: A remote audio controlling system for providing remote audio controlling services over a network environment includes a web server (2), a database (1), a number of monitor computers (5), a number of cameras (60), and a number of audio information output apparatuses (62). The monitor computers, cameras and audio information output apparatuses link to the web server through a network (4). The web server includes a video data obtaining module (22) for obtaining video data from the cameras; an audio data receiving module (23) for receiving audio data from the monitor computers; and an audio data transmitting module (24) for transmitting the received audio data to the audio information output apparatuses. A related remote audio controlling method is also disclosed.
