Abstract: A system for preventing collision of a vehicle with a neighboring vehicle in an aisle of a warehouse, includes: aisle wireless tags; and at the vehicle: a wireless tag transceiver to determine a position of the vehicle in the aisle; a wireless vehicle transceiver to receive a neighboring position of the neighboring vehicle; and a proximity assessing unit comprising an Ultra-Wide Band interface to determine a distance between two vehicles and their relative speeds; and to generate a stimulus, in function of the position and the neighboring position, and/or in function of the distance, and/or in function of the speed of the vehicles.

Abstract: An apparatus for enabling proximity awareness, including: a proximity assessing unit having an Ultra-Wide Band interface to determine a distance between said apparatus and a neighbouring device and/or an orientation of said apparatus with respect to a neighbouring device; a first determining unit determining one or more apparatus parameters; a second determining unit determining one or more neighbouring device parameters; a stimulus generating unit generating a stimulus; and a selecting unit selecting a type and/or an intensity of said stimulus in function of a combination of said distance and/or said orientation, said one or more apparatus parameters and said one or more neighbouring device parameters.

Abstract: A proximity awareness device (101; 200) is able to establish proximity awareness on neighbouring devices (102, 103, 104). The proximity awareness device (101, 200) thereto comprises: a first transceiver (201) configured to implement a ranging protocol to determine a distance and/or angle between the proximity awareness device (101; 200) and at least one of the neighbouring devices (102, 103, 104); and a second transceiver (202) configured to implement a discovery protocol to discover presence of the neighbouring devices (102, 103, 104). The second transceiver (202) consumes less power than the first transceiver (201). In order to further optimize the energy efficiency of the proximity awareness device (101; 200), the first transceiver (201) is controlled to operate according to a first duty cycle (321, 322; 421, 422), and the second transceiver (202) is controlled to operate according to a second duty cycle (323, 324; 423, 424).

Abstract: A method is provided for time accurate execution of MAC logic on a processor able to drive a radio interface. In a first step, a chain of commands is received annotated with a target chain execution time. In a second step, start execution times for the commands are calculated based on the target chain execution time. Then, the chain of commands is executed on this processor at the start execution times.
