Abstract: In an electronic device and a method of generating composite electrical signals, a plurality of post-processing software is installed. An output file, which comprises times and voltages of data points that represent an electrical signal, of an electronic circuit simulation software is loaded, and is read using the installed post-processing software. A time interval of outputs of the electrical signal is obtained by selecting an output type of the electrical signal. The worst bit combination of outputs of the electrical signal is analyzed according to the times, the voltage, and the time interval, and a composite electrical signal is generated according to the worst bit combination.

Abstract: A printed circuit board (PCB) includes a positive differential signal line including first and second segments, a negative differential signal line including third and fourth segments, first and second connecting elements soldered on opposite surfaces of the PCB. The first segment and the fourth segment are located in a first straight line which has a first permittivity. The third segment and the second segment are located in a second straight line which has a second permittivity different from the first permittivity. The first connecting element is connected between the first segment and the second segment. The second connecting element is connected between the third segment and the fourth segment.

Abstract: A method for simplification of a matrix based boosting algorithm divides a feature set comprising a plurality of feature data into several subsets, and assigns a number to each subset. The method selects a plurality of number groups including N subsets randomly. The method further computes a value by boosting algorithm according to each of the number groups for obtaining an acceptable false positive value.

Abstract: A system and method for extracting feature data of dynamic objects selects sequential N frames of a video file up front, where N is a positive integer, and divides each of the N frames into N*N squares. The system and method further selects any n frames from the N frames, selects any n rows and n columns of the n frames to obtain n*n*n squares, where n is a positive integer. The system and method further extracts feature data from the video file by computing averages and differences for pixel values of the n*n*n squares.

Abstract: A composition with catalyst particles for making a circuit pattern is provided. The composition includes an insulation material and a plurality of catalyst particles. The catalyst particles are distributed in the insulation material and not made of metal. When the composition is bathed in a chemical plating solution, a redox reaction takes place between some of the catalyst particles and the chemical plating solution so as to deposit a conductive pattern on the composition.

Abstract: A printed circuit board can support different connectors by selectively setting connection components on the printed circuit board without changing wiring of transmission lines or making new vias in the printed circuit board.

The loading module reads a chip package length file; a layout selecting module reads a layout file and selects high speed serial signals preset by a user; the data processing module selects pins information of a start chip and a terminal chip transmit the selected high speed serial signals and finds the chip package length information, and analyzes interrupt points of the layout character from the start chip and outputs the chip package length information of the start chip, the layout length information, and the chip package length information of the terminal chip in sequence to the output module, to convert into a table and displays the table via a display device.

Abstract: A differential signal transmission device transmits N differential signal pairs from a differential signal generator to a number of receiving terminals. The N differential signal pairs include N positive signals and N negative signals. The N positive signals are clustered at a first positive clustering point. The first positive clustering point is connected to a second positive clustering point via a first matching resistor. The second positive clustering point is grounded via a first grounding resistor, and outputs a number of positive signals to the number of receiving terminals respectively. The N negative signals are clustered at a first negative clustering point. The first negative clustering point is connected to a second negative clustering point via a second matching resistor. The second negative signal clustering point is grounded via a second grounding resistor, and outputs a number of negative signals to the number of receiving terminals respectively.
