Abstract: In some examples, an article may include a layer having a first surface marked with a first code. The article may include a second surface marked with a second code, the second code obscured by the layer to be unreadable through the layer. The first code and the second code may be associated in transaction data stored by a blockchain managed by a consensus network of nodes.

Abstract: The systems and techniques of this disclosure relate to improving work safety in confined spaces by, for example, using machine vision to analyze location marking labels in the confined space to control an unmanned aerial vehicle (UAV) within the confined space. In one example, a system includes a UAV that includes an imaging device and a processor communicatively coupled to the imaging device. The processor may be configured to receive, from the imaging device, an image of a confined space, detect a location marking label within the image, process the image to decode data embedded on the location marking label, and control navigation of the UAV within the confined space based on the data decoded from the location marking label.

Abstract: In general, techniques are described for a personal protective equipment (PPE) management system (PPEMS) that uses images of optical patterns embodied on articles of personal protective equipment (PPEs) to identify safety conditions that correspond to usage of the PPEs. In one example, an article of personal protective equipment (PPE) includes a first optical pattern embodied on a surface of the article of PPE; a second optical pattern embodied on the surface of the article of PPE, wherein a spatial relation between the first optical pattern and the second optical pattern is indicative of an operational status of the article of PPE.
