Abstract: Provided is an automatic collection device for dew on wild herbaceous plants. The automatic collection device includes an electric lifting member, a rotary motor, an electric telescopic rod and a dew collector. The rotary motor drives the dew collector to rotate in a horizontal direction, and a rotation radius is gradually adjusted by the electric telescopic rod. During the rotation of the dew collector, after multiple comb teeth pass through the herbaceous plant, the dew on the multiple comb teeth drops on a water transfer membrane, and the dew is sent by the water transfer membrane into a water collection and guide groove for collection. After the dew collection in one circular area is completed, a tester can uniformly guide the dew into a collection bottle through a water outlet of the water collection and guide groove.

Abstract: This present disclosure is about a wind tunnel balance axial section. A wind tunnel balance is a sensor that measures six force/moment components from a test model in a wind tunnel. An axial section, one of the six measurement sections in the balance, is the hardest section to design because it is often required to measure an axial force which is much smaller than other force components. Therefore, there is a specific design requirement for the axial section to selectively amplify the axial force response and suppress the non-axial responses. This disclosure presents a sensor mechanism composed of elastic linkages to achieve this design requirements for the axial section.

Abstract: An apparatus attaches to a microscope slide to form an enclosed fluidic chamber with input and output ports, where a tissue or cell sample on the slide can be processed using techniques such as immunohistochemical staining. Flow of reagents within the chamber can be laminar and highly uniform across the sample surface to achieve staining that is free of gradients. The sample can be imaged prior to, during, or after any given processing step. Methods for staining and imaging a sample can be implemented through one or more rounds of labeling, label removal or erasure and imaging. Samples can be imaged many times to achieve very high multiplexing levels. Samples can be placed on an imaging apparatus at various times and removed from the imaging apparatus for certain steps.

Abstract: A substation power transformer monitoring system having a transformer monitor that receives oil level signals, nitrogen flow rate signals, 52b breaker status signals, and valve actuator position signals, and then executes instructions based on those signals to determine when predefined radiator section isolation conditions are met. When the conditions are met, control signals are sent to valve actuators of the valves of each radiator section to close or open those valves based on the predefined radiator section isolation conditions, or based on remote manual commands, to isolate particular damaged radiator sections. Thus, the system can address terrorism and/or vandalism of a power transformer in a substation. If some radiator fins are shot or otherwise damaged, causing oil to flow out of the cooling system of the transformer, the system can quickly detect and isolate the leak to prevent further damage to the transformer, while also preventing a larger oil spill.
