According to one aspect of the present disclosure, a device and technique for impact detection and indication is disclosed. The impact indicator includes a first member having a reservoir for holding an indicator fluid; a second member couplable to the first member; and a disc member disposed at least partially between the first and second members and extending over the reservoir. A capillary gap is formed at an interface between the disc member and a surface of the first member facing the disc member. Responsive to receiving a predetermined level of impact, the indicator fluid moves from the reservoir to the interface between the disc member and the first member and wicks into the capillary gap via capillary action, the indicator fluid disposed within the capillary gap providing a visual indication of the received predetermined level of impact.

An impact detector includes a case, an impact indicator disposed on a front side of the case, to indicate an impact history of the impact detector, a first weight that moves inside the case to a side to which the case falls, causing the impact indicator to indicate the impact history by moving through at least one of a first transition path and a second transition path, a first guide member to guide the first weight to a first impact detection position along the first transition path when the case falls in a first direction, and a second guide member to guide the first weight to the second impact detection position along the second transition path when the case falls in a second direction. The first transition path at least partly overlaps with the second transition path on a projection plane on the front side of the case.

The invention discloses a method and a system for automatically partitioning urban spatial form. The method comprises the following steps: acquiring basic data of urban spatial form within a given range, and obtaining a plurality of spatial units; for each spatial unit, a summary table of urban spatial morphological characteristics is generated automatically according to the set urban spatial morphological indexes. The matrix corresponding to the summary table of urban spatial morphology features is clustered by unsupervised clustering algorithm. In the clustering process, different clusteringparameters are set to cluster several times, and the clustering results are scored to determine the best clustering results. According to the best clustering result, the result of automatic partitionof urban spatial morphology is obtained. Furthermore, the correlation between the indicators can be analyzed and the key impact indicators can be obtained. The invention can objectively and comprehensively understand the characteristics of the urban spatial form, thereby forming the result of the automatic zoning and the key influence index, and avoiding the problems of subjective judgment or single dimension of inspection and the like that easily occur in the traditional method.

The application discloses a blunt impact indicator method. Systems and methods using fluid-filled hollow microspheres to assist in monitoring or indicating high-energy blunt impacts on structures such as aircraft. A multiplicity of microspheres may be adhered to or embedded in a coating applied on a surface of a substrate (e.g., a tape or an applique), which substrate in turn can be adhered to a surface of a structure to be monitored. The microspheres are designed to rupture at one or more specified pressure thresholds. In some embodiments, the microspheres are filled with electrically conductive fluid which, if released from ruptured microsphere, changes the electromagnetic state of the substrate. In response to the detection of a sufficiently large change in the electromagnetic state of the substrate, a blunt impact indication is generated. The impact site may then undergo nondestructive inspection.
