Location determination system having mesh infrastructure to reduce power consumption
The present disclosure relates to a location determination system that includes acoustic transmitting devices (104), location tags (112), and a wireless mesh network (106), 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.
Locating systems and methods for wireless seat belt monitoring in vehicles with removable or reconfigurable seats
Locating systems and methods for wireless seat belt monitoring in vehicles with removable or reconfigurable seats are provided herein. An example remote transceiver can be centrally located on a seat that is configured to be rearranged within a vehicle. The remote transceiver can include a processor and memory for storing instructions that include a unique code identifying the remote transceiver. The processor executes the instructions to receive low power signals from transmitters within an interior of the vehicle, determine received signal strength values of the low power signals. The received signal strength values are used by the vehicle receiver to determine a location of the remote transceiver within the vehicle.
