A detection kit applied for detecting a body fluid sample of an organism includes a sampling device and a detecting device. The sampling device includes a sampling unit and a filtering unit detachably covering the sampling unit. The sampling unit collects the body fluid sample that is filtered by the filtering unit. The detecting device includes at least one reaction zone including a fiber substrate and a detecting reagent immobilized to the fiber substrate. The reaction zone is disposed as the fiber substrate contacts the body fluid sample collected by the sampling unit. The fiber substrate absorbs the body fluid sample collected by the sampling unit, so that the body fluid sample reacts with the detecting reagent for the detection. A detection method for detecting a body fluid sample is also disclosed. This invention is advantageous for simplified pretreatment, less amount of the reagent and rapid analysis.

The testing method comprises the following steps: 1) entering into the client of the automatic testing system of the production line and selecting the type of the test terminal equipment according to the interface prompt of the terminal testing program before testing the equipment; 2) setting the communication parameters; 3) carrying out functional test; 4) sending extra instructions; 5) testing the extra functions; and 6) inquiring the test record.

Disclosed is an LED light fixture power supply. The LED light fixture power supply comprises a primary circuit module, a secondary circuit module electrically coupled to the primary circuit module, a PWM light modulation control circuit module electrically connected with the secondary circuit module, and an EMI filtering module electrically connected with the PWM light modulation control circuit module. The PWM light modulation control circuit module is electrically coupled to the primary circuit module to obtain electric power and transmits light modulation signals to the secondary circuit module. The EMI filtering module, the PWM light modulation control circuit module and the primary circuit module form a loop for eliminating common-mode interference signals generated when the PWM light modulation control circuit module outputs PWM signals. The loop formed by the EMI filtering module inside the power supply can eliminate the common-mode interference signals generated when the PWM light modulation control circuit module outputs the PWM signals so that the common-mode interference signals are prevented from penetration into an EMI test network and the purpose of successful EMI testing is realized.

The invention discloses a system for simulating a USIM card in an LTE terminal test, comprising a test system, a man-machine interaction interface MMI, a terminal tested module, a simulated USIM module and an NV module; the method includes the following steps: S1, configuring NV test information ; S2. Read the configuration information and data items of the NV; S3. Set the data information of the simulated USIM system; S4. Use the information of the simulated USIM to search the network, use the data to authenticate the network, and use the simulated USIM system to replace the physical USIM card And update the information in the registration process in real time. The method and system proposed by the present invention have low production cost, convenient testing, automatic batch testing, and avoid test failure in abnormal situations. In the case of USIM card, card slot damage or poor contact of the machine card, the test can be continued. When the data of the physical USIM card is abnormal, you can directly enter the debugging work of the test case.

The invention discloses a test method for simulating system faults based on a USB disk. Connect the USB disk to the device under test; restart the target test system in the device under test to trigger the fault corresponding to the preset fault injection script; execute the test in the fault state; remove the target USB disk after the test is completed. The function of making a USB disk into a system installation startup disk, and connecting the USB disk with preset faults to the device of the system under test, so that the fault is directly injected into the system under test, at this time, the verification of the fault handling process can be carried out. Moreover, the fault can be automatically resolved after the USB disk is removed, so as to realize the next step of processing the system under test after simulating the fault repair, which not only achieves the purpose of the test, but also makes the test method more simple, direct and accurate.
