GEO-REFERENCING IDENTIFICATION (GRID) TAG
20190219703 · 2019-07-18 ·

A system for tagging and tracking assets anywhere in the world under any environmental condition. Geo-Referencing Identification (GRID) tag, GRID satellite (GRIDSAT) tag and associated cloud infrastructure and user interface meet the objectives of a robust global tagging and tracking system. The GRID tag can be used to identify pieces of equipment or storage containers for low-value or aggregate equipment. GRID tags communicate with each other using a mesh radio in each tag. The GRIDSAT tag consists of a satellite modem, global positioning system (GPS) receiver, and mesh radio and can be used by itself for high-value items, large shipping containers, or vehicles and vessels to track and locate them, or used in concert with GRID tags that communicate with each other and with the GRIDSAT tag by means of mesh radio.

20190208381 · 2019-07-04 · ·

The present disclosure relates to a location determination system that includes acoustic transmitting devices, location tags, and a wireless mesh network, where the wireless mesh network uses battery-powered devices. A location tag receives acoustic signals (e.g., ultrasound signals) from an acoustic transmitting device. Clocks from members of the wireless mesh network are synchronized by observation of clock pairings, each clock pair formed by respective clocks in a transmitting device that transmits a message and a receiving device that receives the message. By analyzing the observed clock pairings, a best fit between the clock pairings may be determined. After selecting a reference clock, an acoustic transmission schedule may be propagated to the respective acoustic transmitting device.
