20140037073 | NETWORK AUDIO TESTING SYSTEM AND NETWORK AUDIO TESTING METHOD THEREOF - A network audio testing system and a network audio testing method thereof for testing the performance of a network communication, system during communication are disclosed. The system includes a processing system and a sound simulation device. The processing system is for generating a near-end simulation signal and a far-end simulation signal. The sound simulation device is for receiving and making a near-end simulation sound. The near-end simulation sound is received by a microphone of the network communication system to generate a first test signal. The processing system further simultaneously makes the sound simulation device sounding the near-end simulation sound and a speaker sounding a far-end simulation sound to obtain a second test signal. The processing system compares the first and the second test signal to obtain an attenuation degree of the near-end simulation signal and a residual energy of the far-end simulation signal. | 02-06-2014 |
20140028247 | ANGLE ADJUSTABLE CONNECTING MODULE - An angle adjustable connecting module comprises a casing and a connecting assembly. The casing has an opening. The connecting assembly includes a connecting portion, a shaft and at least an elastic member. The connecting portion is connected with the shaft, an end of the elastic member is connected with the shaft and the other end of the elastic member is connected with the casing, and the shaft is rotatably disposed at the casing for allowing a part of the connecting portion to be movably exposed to the opening. Thus, the wear problem generated as connecting with the game controller can be reduced for ensuring that the functions are normally operated to extend the lifetime of the game controller. | 01-30-2014 |
20130241374 | Isolation Device - An isolation device includes a frame body and a cover body. The frame body is formed through stamping, and includes a base body and an abutting member. The abutting member is connected at a periphery at a side of the base body. The cover body includes a main body and a clamping member. The clamping member is connected at a periphery of the main body, and is inserted in the frame body at the cover body. The abutting member abuts tightly against the clamping member, thereby seamlessly integrating the cover body and the frame body. After the cover body is inserted in the frame body, the abutting member abuts tightly against the clamping member, achieving a seamless integration effect. | 09-19-2013 |
20110194320 | Power Device - A power device includes a power supply module, a first electrical isolation unit, a second electrical isolation unit, a feedback control unit, and a comparing unit. The power supply module includes a feedback compensating terminal and an output terminal, the feedback compensating terminal provides a related voltage of output power, and the output terminal provides an output voltage. When the related voltage of output power is smaller than the predetermined voltage, the comparing unit controls the first electrical isolation unit to change operation of the feedback control unit and the second electrical isolation unit, to allow the power supply module to adjust the output voltage. | 08-11-2011 |
20100043032 | Electronic Device for Supporting Multimedia Over Coax Alliance Standard - The invention discloses an electronic device for supporting a multimedia over coax alliance (MoCA) standard. The electronic device is coupled with a coaxial cable. The electronic device includes an input terminal, a back stage processing unit, and a band pass filter. The input terminal is coupled with the coaxial cable. The band pass filter is coupled between the input terminal and the back stage processing unit, and it receives an input signal from the input terminal. The band pass filter allows a plurality of television channel signals in a predetermined frequency range to pass through and transmits them to the back stage processing unit to be processed. The band pass filter rejects a MoCA standard system signal to prevent it from entering the back stage processing unit. | 02-18-2010 |
20090273908 | NETWORK TRANSFORMER, NETWORK MODULE THEREOF, AND ELECTRONIC DEVICE THEREOF - The invention discloses a network transformer, a network module thereof, and an electronic device thereof The network transformer includes a plurality of coil sets, an insulating board, a casing and a plurality of pins. The pins are disposed on the casing. The network transformer is disposed on a PCB via the pins. The insulating board is disposed in the casing and connects with at least two side walls of the casing to form a plurality of isolation chambers, each of which is for containing one coil set. | 11-05-2009 |
20090211800 | ELECTROMAGNETIC SHIELDING DEVICE - An electromagnetic shielding device includes a frame and a cover. The frame is formed by bending a strip structure and disposed on a circuit board with an electronic component, and it encloses the electronic component. The cover has a top portion and a plurality of side portions. The side portions are expended and bent from the top portion. When the cover is combined with the frame to enclose the electronic component, the side portions are closely connected to the frame. The cover and the frame are combined to form a shielding space. | 08-27-2009 |
