  • Patent number: 11747009
    Abstract: A lighting apparatus includes a light head, a driver box, multiple separating columns and a light source module. The light head has an Edison cap and a head body. The head body has a rotatable connector. The driver box has a first side and a second side for containing a driver circuit. The first side of the driver box has a fixing unit corresponding to the rotatable connector of the head body to selectively attach or detach the light head from the driver box by rotating the rotatable connector with respect to the fixing unit. The light source plate has a light source plate mounted with LED modules. The light source plate is fixed to the driver box with the multiple separating columns. The separating columns form an air gap between the driver box and the light source for heat dissipation.

  • Patent number: 10955382
    Abstract: An experimental device for studying the propagation characteristics of stress wave in jointed rock mass at high temperatures. The device includes a launch system, a loading system, a measuring system and a heating device. The heating device can be heated in sections to meet complicated test requirements. The measuring system includes two sets of measuring devices to ensure test accuracy. One measuring device uses a strain gauge to measure the local displacement of rock, thus obtaining the change of wave velocity; this method can be used when sample temperature is low. The other device adopts digital image processing technology. The experimental device can control the initial wave form and initial wave velocity, which can better meet the test requirements. The position of the sample can be fine-tuned to avoid the impact of errors left by rock processing on the test results.

  • Patent number: 9781252
    Abstract: The invention provides an information processing method, system and a mobile terminal, which can detect a motion trajectory of the mobile terminal after the mobile terminal receives a call request, and execute a first process when the motion trajectory meets a preset condition. It can be seen that, in the invention, whether a user will answer the call request is determined by the judgment to the motion trajectory of the mobile terminal after the call request is received. After it is determined that the user will answer the call request, the processes, such as automatically answering the call request, closing a screen touching function of a touch screen, or adjusting screen brightness, can be executed, so that the user does not need to perform any manual operation, which on one hand, improves execution efficiency, and on the other hand, avoids a misoperation caused by a manual operation.
