The invention discloses a brake lamp monitoring apparatus and a method using the monitoring apparatus for monitoring invalidation of brake lamps; the monitoring apparatus comprises a bodywork controller (7), a meter (8), a tappet switch (4), the brake lamps (5) and a rear fog lamp (6), wherein, the bodywork controller (7) is connected with a meter (9) by a bus and is used for detecting the state of the brake lamp (5); when one of the brake lamps is out of work, a brake fault indicating lamp arranged on the meter is caused to twinkle after the meter (8) receives the information. When the two brake lamps (5) are out of work at the same time, the fog lamp (6) is controlled to be lightened, and the brake fault indicating lamps on the meter (8) are simultaneously controlled to be lightened. The brake lamp monitoring apparatus can ensure the wiring to be simpler by adding a tail lamp driving module (9). By utilizing the technical proposal of the invention, the substitute proposal can be adopted after the self of the brake lamp has fault and is out of work; the brake lamp monitoring apparatus can automatically warn the succeeding vehicles, and simultaneously notice the driver that the brake lamps are out of work and need to be repaired as soon as possible by using the meter, thereby leading the drive to be safer.

The invention relates to a system for signalling and locating vehicles involved in accidents, stopped vehicles and vehicles with mechanical problems in daytime and night-time conditions as well as in adverse weather conditions. According to the invention, the occupants of the vehicle can raise the alarm without leaving the vehicle such as to avoid any physical risk. The invention comprises a case and a hinged cover housing an air container. One end of the air container is connected to a gaseous fluid outlet pipe and to a manual quick-opening non-return valve which is located in the mouth of an empty aerostatic inflatable fluorescent body. The aforementioned body is folded inside the case when not in use and is deployed in the event of a vehicle impact by means of a device comprising an inertia sensor which is activated by a deceleration force exceeding 3G and which is powered by a power source comprising batteries or accumulators belonging to the electric circuit of the vehicle or independent batteries. Said source is solidly connected to an electrically-conductive cable terminating in a connector which is associated with a light flashing apparatus comprising an electronic flash unit, a light sensor which operates at night and a satellite-based mini-localizer comprising a global positioning system (GPS).

The present disclosure relates to an event reminding method and apparatus. The method comprises: when receiving a to-be-reminded event, determining whether a terminal is playing preset sound information by means of a wireless earphone connected to the terminal; and when a determination result is that the terminal is playing the preset sound information by means of the wireless earphone connected to the terminal, sending a silent reminding command to the wireless earphone according to the to-be-reminded event, wherein the silent reminding command is used for controlling the wireless earphone to perform a silent reminding operation. By means of the technical scheme, when the terminal receives the to-be-reminded event, if the terminal is playing the preset sound information by means of the wireless earphone connected to the terminal, the silent reminding command is sent to the wireless earphone, so as to enable the wireless earphone to perform the silent reminding operation, such as a vibration reminding operation, a light flashing reminding operation and the like, so that not only be the preset sound information which is being played will not interrupted but also normally reminding a user of a reminded event can be ensured, and the user experience is improved.

The invention provides a stable precise visual weld joint tracking system, which comprises a welding gun, a laser, a double-target-surface imaging device, a processor and a controller which are arranged on a moving platform, wherein the laser projects structured light to the periphery of to-be-welded seam; the double-target-surface imaging device acquires welding area image signals at the same time; the processor processes a structured light image modulated by the to-be-welded seam and controls the moving platform to perform rough adjustment through the controller; meanwhile, the processor acquires a space pose deviation parameter of the welding gun in real time according to an imaging feature parameter acquired by image fusion and according to relative pose parameters among the laser, the double-target-surface imaging device and the to-be-welded seam, and performs fine adjustment on the relative space pose of the welding gun through the controller. The stable precise visual weld joint tracking system has the beneficial effects that the moving platform is subjected to rough adjustment and the welding gun is subjected to fine adjustment, and the laser emits the structured light to the to-be-welded seam, so the influence of arc light flashing is resisted and the tracking system is more stable and precise.
