Abstract: A compute device includes: a substrate; a circuit trace that is coupled to electronic components, wherein the electronic components include at least a processor, memory, and transceiver; a power source (battery and/or solar element) coupled with the electronic components; an antenna layer over the substrate that has at least one primary antenna element of at least one antenna assembly, wherein each antenna assembly is operationally coupled with the transceiver as a data communication link, and each primary antenna element is operationally coupled to the electronic components or power source as a structure of at least one ground plane for the respective primary antenna element; and a coupling member configured for being coupled to an object. In some aspects, the power source is selected from a, battery, solar element, or combinations thereof.

Abstract: A method may include collecting from each of multiple endpoint devices a set of anonymized interactions of the corresponding endpoint device with other endpoint devices. Each anonymized interaction in the set of anonymized interactions may be based on an ephemeral unique identifier of another endpoint device involved in a corresponding anonymized interaction with the corresponding endpoint device. The method may include, for each endpoint device, resolving identities of the other endpoint devices with which the corresponding endpoint device has interacted from the corresponding set of anonymized interactions.

Abstract: A method may include receiving a beacon from a first intermediate device via a first network, the beacon being received by the first intermediate device from an endpoint device via a second network. The beacon may include a hash value based at least in part on the identity of the endpoint device and a time unit when the beacon was generated. The hash value of the beacon may be validated based on the identity of the endpoint device and the time unit when the beacon was generated. The beacon may be forwarded to a server via a third network in response to the hash value of the beacon being valid.

Abstract: A system may include processing logic configured to execute instructions to cause a system to perform operations including receiving, from an intermediate device, data that originated at an endpoint node. The data may be associated with metadata that was associated with the data by the intermediate device. The operations may also include extracting one or more items from the metadata. The operations may include validating an activity of the intermediate device based on the one or more items that were extracted from the metadata.

Abstract: A system may include processing logic configured to execute instructions to cause a system to perform operations including receiving a beacon from a first intermediate device via a first network. The operations may also include identifying a characteristic of the beacon. The operations may include identifying, based on the characteristic of the beacon, a server that is associated with the beacon. The operations may include sending a beacon message to the server via a third network.
