This invention proposes a non-contact in-vehicle alcohol screening device and system. It includes a transmitting module, a receiving module, a main control and power module, a housing, and a light-shielding structure. The alcohol screening device is connected to a remote management platform. The device also includes a communication module for sending test results, test time, and device identification information to the remote management platform. The transmitting module uses dual Class 1 low-power lasers, combined with real-time current monitoring and a self-locking switch in the main control module, providing triple protection for human safety through light source, circuitry, and mechanical operation. This ensures that even direct laser light into the eyes is harmless, meeting the safety and compliance requirements of law enforcement scenarios. The receiving module is equipped with a bandpass filter with a corresponding center frequency to effectively suppress ambient stray light and circuit noise. Simultaneously, the dual-wavelength differential design, through the ratio calculated by the main control module, jointly cancels common interferences such as water vapor and window reflections, significantly improving the reliability of the screening signal in complex environments.

This application discloses a method, related equipment, and computer program product for preventing pets from attacking humans. By detecting the pet's multimodal data through a pet collar, it automatically identifies whether the pet exhibits aggressive tendencies and can accurately recall various scenarios where such tendencies might occur. Furthermore, when aggressive tendencies are determined, environmental information surrounding the pet is collected by an environmental sensing unit on the pet collar. If a human object is identified within this environmental information, it can be assumed that the pet has a high probability of attacking a human. In this case, the pet collar outputs deterrent measures to stop the pet's aggressive behavior. The pet collar provided by this application avoids meaningless deterrent measures (such as when the pet exhibits aggressive tendencies due to a sudden loud noise in the environment when there are no people around, in which case there is no issue of the pet attacking a human), while also effectively preventing pet attacks on humans and protecting human safety.

This invention discloses a feeding mechanism for a natural rubber pressing machine. By setting an auxiliary lifting device on the main lifting device, the main lifting device drives the auxiliary lifting device to move linearly up and down along the support. The auxiliary lifting device drives the clot hook to retract and lower, thereby feeding and pressing the rubber clot. This achieves a high degree of automation, eliminating the need for manual pushing of the clot, significantly reducing the labor intensity of feeding the pressing machine, improving feeding efficiency, effectively reducing labor costs, and ensuring the personal safety of workers. At the same time, by setting two sets of auxiliary lifting devices on the support, the main lifting motor drives the gear set to drive the main screw to rotate synchronously in opposite directions. This allows the auxiliary lifting devices on the two main screws to drive the clot hook to feed in an alternating and continuous manner, effectively improving the continuity of production, further increasing feeding efficiency, improving production efficiency, and reducing consumption.
