Abstract: Disclosed is a system capable of simultaneously performing a thermal test, an electrical test, and a mechanical test in an environment similar to the installation environment of a dynamic cable. The system includes a seawater tank module configured to form a seawater environment for a test cable, a mechanical test module configured to perform mechanical aging of the test cable according to an actuator operation, an electrical test module configured to perform electrical aging of the test cable by applying a voltage to each of opposite ends of the test cable, a thermal test module configured to perform thermal aging by applying a current to a dummy cable formed independently of the test cable, and a control module configured to perform data input, control processing, monitoring, and storage of the seawater tank module, the mechanical test module, the thermal test module, and the electrical test module.

Abstract: An improved apparatus for reducing flickers of an encoder capable of advantageously reducing flickers occurred when video signals are converted from a non-interlace scanning method to an interlace scanning method in the digital method, which includes a graphic controller for outputting a pixel signal by a line unit and for outputting a pixel clock, a horizontal synchronous signal and a vertical synchronous signal; a synchronous signal converter for converting a pixel clock, a horizontal synchronous signal and a vertical synchronous signal outputted from the graphic controller to a pixel clock, a horizontal synchronous signal and a vertical synchronous signal of an interlace scanning method; a control signal generator for outputting a control signal by receiving a pixel clock, a horizontal synchronous signal and a vertical synchronous signal of an interlace scanning method outputted from the synchronous signal converter; a line store unit for selecting a pixel data corresponding to nth even scanning line among
