The portable laser monitoring system can collect nano-scale vibration information (caused by sound) of different items by laser under the condition of long distance and noisy environment, and then restore clear sound by algorithm.

Multi-functional Drug Analyzer is a powerful handheld drug analyzer.It can rapidly detect the presence of specific drugs in human specimens (urine/saliva/hair) that exceed the cut-off concentration, to get qualitative or quantitative results.
It can be used with a matching colloidal gold reagent card or fluorescent reagent card, to qualitative or quantitative rapid detect the presence of specific drugs in human samples that exceed the cut- off concentration.

C4I-801 is a non-linear junction detector. It can detect any electronic equipment hidden in walls, floors, ceilings, lamps, furniture or containers. Whether these electronic devices are transmitting signals or not, they are alerted by display, vibration and sound prompts, so that the detectors can focus on the hidden targets

C4I-420 3D through wall radar is a detection device based on UWB radart echnology and biomedical engineering technology. It can penetrate obstacless uch as building walls, and obtain real-time information such as 3D imaging, position, posture, and quantity of human targets. It is widely applied for variety of emergency search tasks include but not limited to street fighting, counter terrorism, hostage rescue, border security, etc.

Portable intelligent reconnaissance robot is rugged, small and lightweight, perfect to carry on as a back-pack. The robot survives dropping on ground and can be quickly deployed in narrow spaces, moving quietly and fast, equipped with cameras and pickups to collect real-time audio and video data of on-site environment, even in darkness.
Individuals can remotely manipulate the robot to certain places or dangerous areas while maintaining a safe distance, monitoring the place or target objects in real time, so as to make decisions and actions quickly. The robot weighs 3.2 kg, and survives dropping from a height of 5 meters to concrete. It supports rapid replacement function modules, equipping with 3D LiDAR mapping module to build 3D point cloud model, 2D LiDAR to create layout of environment for autonomous navigation and obstacle avoidance, robotic arm to handle hazardous materials.

Pupil changes are primarily influenced by the central nervous system, After drug use, the central nervous systemis impaired, leading to abnormal pupil responses to light. The pupil detection device applies a light stimulus to the eye (based on the principle of the pupillary light reflex). This stimulus inevitably causes changes in the pupil which are then analyzed to determine whether the subject is suspected of drug use. Our approach combines pupil feature detection with traditional methods for detecting eyeball lesions (e.g., identifying concave spots, speckles, radial patterns, pigmentation, ciliary features, and other detailed characteristics),significantly enhancing accuracy.

Thrown Detective Robot is a small detective robot with light weight, low walking noise, strong and durable. It also takes into account the design requirements of low power consumption, high performance and portability. The two-wheeled detective robot platform has the advantages of simple structure, convenient control, flexible mobility and strong cross-country ability. The built-in high-definition image sensor, pickup and auxiliary light can effectively collect environmental information, realize remote visual combat command and day and night reconnaissance operations, with high reliability. The robot control terminal is ergonomically designed, compact and convenient, with complete functions, which can effectively improve the working efficiency of the command personnel.
