US11403924B2 Radiobeacon data sharing by forwarding low energy transmissions to a cloud host
Remote actuation of machines or machine systems is realized by a system for coupling a radiobeacon to a smart device and in turn to a broader network. The smart device is configured as a proximity-actuated “community nodal device” by an application that operates as part of the system. The community nodal device is given instructions to function as a “soft switch”: to automatically “upswitch”, amplify, and broadcast low energy, local area radiobeacon “messages” to a cloud-based server, where the message is interpreted according to rules or policies established by an operator, and a command is transmitted for execution to a remote device. Conventional smart devices generally discard data not addressed to the owner of the smart device. Instead of discarding third party messages, the system preempts their handling, and using a soft switch formed from background resources, anonymously, without access to the message by a user interface of the proxy device, and without waiting for a network query from the host, engineers an “upswitched transmission” of radiobeacon-generated data to a cloud host. Advantageously, confidential sharing of ad hoc community resources results in a negligible load on background resources of the community nodal device. Messages may include a sensor data payload. Bit overloading enables a sensor data payload to be compressed into a few hundred bytes or less.
