Abstract: In an aspect, an asset tracking coordination component estimates a time of a beacon transmission from a wireless energy charging-capable device coupled to an asset within a threshold proximity of a scanning device based on an estimated distance between the asset tracking coordination device and the scanning device and timing information associated with a wireless energy transmission, and schedules a beacon scanning window for the scanning device to scan for the beacon transmission based on the estimated time. In a further aspect, a scanning device may both provide a wireless energy transmission and may also scan for beacon transmission(s) from wireless energy charging-capable device(s) during a beacon scanning window.

Abstract: This disclosure provides systems, methods, and devices for Electronic Shelf Label (ESL) systems that support positioning of ESL devices. In a first aspect, a method includes: transmitting, to each ESL device in a group of ESL devices deployed within an environment via a wireless network associated with the environment, a command to emit one or more flashes of light over a flash interval associated with the group; receiving, from a mobile device via the wireless network, visual data collected for the group by a camera during the flash interval; detecting, within the visual data, the one or more flashes emitted by each ESL device in the group over the flash interval; and determining a location within the environment of each ESL device in the group based on the one or more flashes emitted by each ESL device in the visual data. Other aspects and features are also claimed and described.
