The application discloses a kind of based on double light activation layer's super-sensitivity phototransistor.The phototransistor described in the application is sequentially composed of gate electrode (Si), dielectric layer (HfO2), photoactive ion layer (PbI2), channel (WSe2) and source-drain electrode (Au) from bottom to top.The phototransistor described in the application exhibits extremely high sensitivity advantage: on the one hand, it meets the test demand in extremely weak light environment, and the dark field light intensity detected by it is lower than that of commercial phototransistor by 4 orders of magnitude;On the other hand, its responsivity is higher than that of commercial product by 4 orders of magnitude.PbI2, a photoactive ion layer, is introduced into the traditional phototransistor structure based on traditional two-dimensional material for the first time, which greatly improves the sensitivity of the device and provides a new idea for the development of extremely dark field detection technology.

A stroboscopic device to use a camera and a light source with software that generates synthetic and real video frames, compares the frames via a discriminator, repeat until a convergenc point is achieved where the discriminator can't reliably tell the real video frames from the synthetic video frames, analyzes a dense optical flow field between a first and second frame in a sequence of video frames to detect a motion, and controls a light activation to achieve a stroboscopic effect, wherein once achieved, a system identifies an object and automatically detects movement or vibration of the idenfied object using a trained model, enabling precise visualization and analysis of fast motions in video sequences.

The preparation method of a phosphorescent group 7H-indole [2,3-c] quinoline series derivative with light response belongs to the field of organic intelligent materials. Several organic phosphorescent materials with NBCz as the core provided in the application can realize a color change from green or yellow-green afterglow to orange-yellow afterglow under the influence of different light activation times of a 365nm ultraviolet lamp, so as to achieve light-induced phosphorescent color change-stimulative response, and therefore can be widely applied to anti-counterfeiting, data encryption and sensing applications. The organic phosphorescent material with NBCz as the core has the following advantages: (1) simple and easy-to-follow synthesis route; (2) simple light activation condition; (3) large stokes shift, and remarkable effect.

A feature-rich, improved vehicle traffic signal control system that uses network technology is provided herein. For example, the improved vehicle traffic signal control system may include a control box and light heads that include processors. The control box in the improved vehicle traffic signal control system may include fewer components and / or fewer wires extending therefrom as compared to a typical control box. In particular, the control box in the improved vehicle traffic signal control system may not include relays, a conflict monitor, or other similar components. Rather, the improved control box may simply include a controller that is coupled to various light heads via Ethernet cables. The Ethernet cables can carry electrical power, thereby providing power to the light heads. The light head processors can use network technology to control light activation, to perform conflict monitoring, to receive data from various sensors to adjust traffic flow, etc.

An agricultural vehicle having a cart operably coupled thereto. The agricultural vehicle may include a guidance system for controlling operation of the agricultural vehicle and the cart and including: at least one processor; and at least one storage medium storing instructions thereon that, when executed by the at least one processor, cause the guidance system, during an agricultural operation, to: capture image data of a plurality of transport vehicles; analyze the captured image data to identify a candidate target transport vehicle of the plurality of transport vehicles; activate a light emitting device of an intended target transport vehicle; detect light emitted by the light emitting device to verify the candidate target transport vehicle matches the intended target transport vehicle; and responsive to identifying and verifying the candidate target transport vehicle of the plurality of transport vehicles, cause the agricultural vehicle to automatically align with the candidate target transport vehicle.
