摘要： The present invention provides a system and methods for filtering fluid using filter papers, stationary paper, cloth sheets or any other porous material. In one embodiment, the present invention uses the lateral flow direction along the porous sheets, instead of conventional vertical flow direction, for the removal of bacteria and particle contamination in the range from nanometers to millimeters. The pore sizes in the filter media along the lateral direction are modulated by controlling the compression of the porous sheets, instead of conventionally designing filters with different pore sizes. The lateral flow fluid filter system is scalable simply by increasing the feed area, feed length, and the number of porous sheets. The invention presents a universal fluid filtration system for wide range of applications such as water purification, food processing, chemical industry, oil and gas industry, and biological applications.

摘要： State-of-the-art object detection algorithms (e.g., EfficientDet, Faster-RCNN, and YOLO) and their variants are integrated into an end-to-end IoT cloud-based system deployment. The system can (1) receive real-time video streaming (RTSP/RTMP/SDP) from most CCTV systems and devices with cameras, (2) extract frames from the video streams, (3) feed the frames to multiple AI models simultaneously, and (4) compute a probability for the presence of fire and/or smoke. Based on custom risk thresholds, the outputs can be compiled programmatically into a video clip that is sent to a user automatically for real-time alerts.

摘要： A method of manufacturing a microfluidic analytical device comprising providing a top lamination layer and a bottom lamination layer, wherein each of the top lamination layer and bottom lamination layer comprises an outer layer and an inner layer, cutting out one or more channel spaces from the at least one of the top lamination layer and the bottom lamination layer, wherein the one or more channel spaces form a microfluidic path, positioning at least one middle layer between the top lamination layer and the bottom lamination layer, such that each of the two inner layers face the at least one middle layer, and subjecting the top lamination layer and the bottom lamination layer to a process, wherein the process allows both the inner layers to permeate substantially through the at least one middle layer.
