Systems, methods, apparatuses, and computer program products for audio output device testing. For example, some embodiments described herein may provide for audio output device testing in an objective and consistent manner Specifically, some embodiments may provide a system that can be used to determine an array of tests for an audio output device, cause the audio output device to be tested according to the array of tests, compare a performance of the audio output device to a baseline performance, and intelligently and objectively determine a score for the audio output device. In addition, the system may trigger, or perform, certain actions with respect to the audio output device based on the score.

A system is provided to analyze cross-modulation distortion in audio devices, which may include testing with audio frequencies. One or more distortion signals from the audio device may be measured for an amplitude, phase, and or frequency modulation effect. In another embodiment a musical signal may be used as a test signal. Providing additional test signals to the audio device can induce a time varying cross-modulation distortion signal from an output of the audio device. Also utilizing at least one additional filter, filter bank, demodulator and or frequency converter and or frequency multiplier provides extra examination of distortion. Also frequency and or phase response can be measured with the presence of a de-sensing signal and or another signal that induce near slew rate limiting or near overload condition of the device under test.

An automatic testing system includes a platform; a carrier fixed on a surface of the platform for carrying a device under test (DUT); a function test module for testing functions of the DUT; and a shifting module for shifting the function test module.

A display panel and a method for testing for an occurrence of a crack in a display panel are provided. The display panel includes a panel body, a ground line, a first ground connecting portion, a first testing portion, a second ground connecting portion, a second testing portion, and a switch. By measuring a voltage, a resistance, or a current between the first testing portion and the second testing portion, an open circuit in the ground line and a crack in a non-display area can be detected. Therefore, difficulty of confirming if a crack occurs in the display panel is reduced.

An electronic circuit triage device diagnoses functionality of various electronic circuits of an electronic device. The electronic circuit triage device detects whether an electronic circuit is functioning properly by measuring a magnetic field pattern associated with the electronic circuit and comparing the magnetic field pattern to an expected magnetic field pattern.

The test cable includes a patch cable section having a plurality of wires surrounded by a sheath, a first adapter connected to an end of the patch cable section, a plurality of sub-cables that emerge from patch cable section, each sub-cable including a pair of wires continuing from the plurality of wires in the patch cable section, and a plurality of sub-cable adapters connected to the plurality of sub-cables. Characteristically, each sub-cable has a sub-cable adapted thereto. A method for applying the test cable is also provided.

The present disclosure relates to a system for automatically identifying product information, including a lamp information collection module, a controller, and a user terminal. The controller has a built-in comparison table setting different power information intervals for different lamp categories, and sends to-be-collected power information to the lamp information collection module. The lamp information collection module is used to collect corresponding power information according to the received to-be-collected power information and send the collected power information to the controller. The controller is further used to determine a category of a lamp according to the collected power information corresponding to the lamp and the power information interval comparison table, and send information of the lamp to the user terminal. The user terminal includes a human-machine interface and is used to display the information of the lamp on the human-machine interface.
