Abstract: A warning triangle includes a warning board and a warning strip. The warning board includes at least two wheels for mobility and the warning strip is placed along the road between an automobile and the warning board. A first warning strip terminal is connected to the warning board, and a second warning strip terminal includes a power interface to connect to an automobile power source. The warning board receives power via the power interface, the warning board and the warning strip are configured to output a distance warning mark or a request for assistance.

Abstract: A voltage-drop testing system, including a voltage-drop control apparatus, and a voltage-drop testing method adapted for the voltage-drop testing system based on LABVIEW department platform. When the LABVIEW department platform 12 is running, different groups of test data may be transferred to the PLD tester 20, when the PLD tester 20 finishes the testing based on all groups of test data, the PLD tester 20 feeds back the test results to the LABVIEW department platform 12, and the LABVIEW department platform 12 creates the voltage-drop testing graphic frame displaying the test results for the electronic device under test 2 for the convenience of a user.

Abstract: An electromagnetic interference (EMI) inhibiting device which prevents EMI from being transferred through a server cable from the outside to the inside or vice versa. Metal oxide powders packed between the cylinder and the cable act as an absorbant and dissipator of any EMI.

Abstract: A container data center includes a container defining a wire hole therein, a cable extending through the wire hole of the container, and an EMI shielding device preventing electromagnetic radiation from entering into the container from the outside environment or leaking from the container to the outside environment through the wire hole of the container. The EMI shielding device includes a metal cylinder through which the cable extends and an effective amount of metal powder packed between the metal cylinder and the cable for shielding EMI. The metal cylinder has an end thereof inserted into the wire hole of the container and engaged with a circumferential edge of the wire hole. The disclosure further relates to an EMI shielding device.

Abstract: A conductivity measurement device comprises a first body, a second body, a baseplate, a extension rod and a contact pad. The extension rod is positioned inside the first body, the baseplate is positioned on one end of the extension rod, and the contact pad is positioned on the other end of the extension rod. The contact pad contacts the surface to be tested and measures the electrical conductivity thereof with no resulting damage to the surface.

Abstract: An electromagnetic wave absorbing and heat dissipation material includes thermal conductive grains, electromagnetic wave absorbing particles, and thermal conductive adhesive to bond the thermal conductive grains and the electromagnetic wave absorbing particles together. Weight of the thermal conductive grains accounts for total weight of the electromagnetic wave absorbing and heat dissipation material in a range from about 15% to about 25%, weight of the electromagnetic wave absorbing particles accounts for the total weight of the electromagnetic wave absorbing and heat dissipation material in a range from about 25% to about 30%, and weight of the thermal conductive adhesive accounts for the total weight of the electromagnetic wave absorbing and heat dissipation material in a range from about 50% to about 60%.

Abstract: A cooling pad capable of absorbing electromagnetic interference (EMI) is used to be connected between a cooling device and an electronic component. The cooling pad conducts heat generated by the electronic component to the cooling device, thereby to cool the electronic component. The cooling pad includes an EMI absorbing net made of electromagnetic absorbing material. Therefore, the cooling pad is capable of absorbing EMI generated by the electronic component.
