This invention discloses a wind field system and laser processing method for laser patterning, belonging to the field of laser patterning technology. The ion wind component is divided into a central cavity, a first cavity, and a second cavity. The central cavity serves as a blowing channel; in blowing mode, air compressed by an air compressor is ionized under the high pressure of electrodes, forming a charged compressed air stream, which is then blown out from the outlet to the processing area. Both the first and second cavities serve as extraction channels; in extraction mode, the suction force of a dust collector removes processing byproducts from the processing area. The ion wind component is fixedly connected to the laser processing head and can move with the laser processing head, generating a synchronously moving local ion wind field. This allows for timely, uniform, and stable removal of processing byproducts during large-format laser patterning with a small equipment size and low cost, while ensuring wind field uniformity and appropriate force.

A customizable drug delivery system and method utilizing a laser pattern generator (LPG) to define application of a drug delivery payload (DDP) contained within a drug delivery device (DDD) to a drug delivery target (DDT) is disclosed. A computer control device (CCD) supervises the LPG to select a drug payload pathway (DPP) from a drug pathway database (DPD) and writes the selected DPP to the DDD. This pathway patterning process (PPP) modifies the hydrophilic properties of the DDD and enables the DDD to selectively attract and absorb the DDP. The DDD is then injected with the DDP or exposed for drug exposure time (DET) by the CCD and DPD during which the DPP written to the DDD absorbs a controlled amount of DDP. The DDD when subsequently inserted into a drug delivery target (DDT) delivers the DDP to the DDT under controlled delivery rates defined by the DPP and the DET.

This invention relates to the field of UAV visual obstacle avoidance technology, specifically to a UAV binocular visual obstacle avoidance system and its ranging and obstacle avoidance methods. By adding a laser module to a dual-UAV binocular visual obstacle avoidance system to emit customized patterns combined with filters, it solves the obstacle avoidance problem in low light or when binocular vision is abnormal. The laser module can supplement environmental texture and light, allowing binocular vision to function normally again. Alternatively, a monocular ranging and coordination scheme can be used, projecting the laser pattern onto the reflective surface of the obstacle.

It achieves flexible adaptation between normal binocular operation and abnormal switching, significantly improving the stability of UAV obstacle avoidance and its adaptability to complex environments.
