Abstract: A method and a device for communication failure detection are provided. The method includes the following steps. Obtaining a piece of located path information of an unmanned vehicle. The piece of located path information indicates the unmanned vehicle is located at the located path of a plurality of paths in a route. Selecting one of a plurality of allowable periods as a located path allowable period according to the located path information. Setting a timer and starting the timer according to the located path allowable period. Under a condition that a communication module receives a periodic message before the timer reaches the located path allowable period, resetting the timer. Under a condition that the communication module does not receive the periodic message when the timer reaches the located path allowable period, determining that a communication failure occurs.

Abstract: A method and system of measuring a radio wave distribution of a radio signal source and estimating corresponding radio characteristics by using a flying vehicle is provided. The method includes the following steps. At a number of flight positions during a measurement process, a number of first radio signals transmitted by the radio signal source are measured by the flying vehicle. A position of the radio signal source is estimated according to the first radio signals and a radio channel model. A number of first radio characteristics of the first radio signal are obtained, and a radio wave distribution of the radio signal source is estimated according to the first radio characteristics of the first radio signals and a number of second radio characteristics of a number of second radio signals in the radio wave distribution are estimated according to the first radio characteristics of the first radio signals.

Abstract: A method and a system for vehicle head direction compensation are disclosed. The method includes the following. A relative position between each of a plurality of sensors disposed on a vehicle and a plurality of base stations is obtained through the sensors and a relative coordinate system is established by a processor to obtain a vehicle head direction of the vehicle in the relative coordinate system and a deviation angle between an X-axis of the relative coordinate system and a true north azimuth. An angle compensation is performed by the processor on the vehicle head direction of the vehicle in the relative coordinate system based on the deviation angle.

Abstract: An exemplary embodiment of a system for updating electronic shelf labels (ESLs) comprises multiple ESLs, and a gateway connected to the multiple ESLs to update data of the multiple ESLs. Each ESL comprises a transceiver having a media condition detector to detect whether other ESL(s) perform an update at the time slot, a controller, a memory, and a random number generator randomly selecting one of multiple time slots of a frame when an ESL update procedure begins, wherein the time slot corresponds to an index stored in the memory by the controller. The ESL performs the update at this time slot when none of said other ESL(s) performs the update at the time slot. When said other ESL(s) performs the update at the time slot, the controller enables the random number generator to randomly select another time slot from a next time frame.
