  • Patent number: 11129042
    Abstract: Presented herein are systems and methods for detecting a boundary line crossing based on Round Trip Time (RTT) measured for wireless signals transmitted between and initiator wireless transceiver and a responder wireless transceiver deployed to form a straight boundary line. The initiator wireless transceiver transmits wireless probe signal(s) to the responder wireless transceiver, receives a wireless response signal transmitted by the responder wireless transceiver in response to the wireless probe signal(s), calculates an RTT combining a travel time of the wireless probe signal(s) and the travel time of the wireless response signal(s), compares the RTT to a reference RTT computed for a wireless probe signal and a corresponding wireless response signal transmitted in a clear straight transmission path while the boundary line is clear of obstacles and determines whether an object is blocking the straight transmission path based on a deviation of the RTT from the reference RTT.

  • Publication number: 20200389288
    Abstract: A computing device comprises a network element configured for receiving messages sent over a network from a control facility, a reduced instruction set computer processing circuitry comprising a central processing unit (CPU) and a secure hardware-implemented module adapted to verify that a signed PKI message is encoded in the received messages at a plurality of sequential intervals and to either switch the CPU from an operational state to a safe state, or prevent switching of the CPU from the safe state to the operational state, when a receipt of a signed PKI message is not verified in one of the sequential intervals. In the operational state, the CPU accesses a memory address space in the processing circuitry for executing software-based commands. In the safe state the CPU is prevented from executing the software-based commands while access to the memory address space is retained.
