Abstract: System and methods are provided for warning a worker of a rail vehicle, or an operator of the rail vehicle of the worker. The system includes a worker device, a vehicle device, and a central server. The devices and server operate on one or a combination of actual or simulated satellite navigational signals, and beacon signals to determine the position of the devices, to generate a warning. The position determination may prioritize beacon signals over satellite navigation signals. The position determination may involve correcting a calculated position based on a measured power level of the beacon signal received from the beacon transmitter, an elapsed time since a previous beacon signal was last received by the device from the beacon transmitter, an elapsed time since a previous satellite navigation signal was received by the device, or an accuracy of the position of the device based on the satellite navigation signal.

The example method further includes identifying a QoE priority associated with the second device and adjusting the window size based on the QoE priority. Further, the example method includes transmitting the data packet to the second device.

Abstract: Techniques directed to utilizing networked devices to enhance user experience are described. In an example, sensor data received from sensor(s) associated with a facility can be used to determine a presence of a user equipment (UE) within or proximate to the facility. Based at least in part on the sensor data, an account associated with the UE can be accessed. Based at least in part on account data associated with the account, a distribution of network technology can be modified to temporarily enable the UE to access a service that is not otherwise available to at least one other UE within or proximate to the facility.

Abstract: A circuit for performing clock recovery according to a received digital signal. The circuit includes at least an edge sampler and a data sampler for sampling the digital signal, and a clock signal supply circuit. The clock signal supply circuit provides edge clock and data clock signals offset in phase from one another to the respective clock inputs of the edge sampler and the data sampler. A digital phase detector determines if the data clock is early, late or synchronized with respect to data value transitions in the digital signal, and based on that determination provides a phase adjustment signal to the clock signal supply circuit, which is operable to vary phases of the data and edge clock signals accordingly.
