CONTEXT-AWARE COLLISON DEVICES AND COLLISON AVOIDANCE SYSTEM COMPRISING THE SAME

摘要

Personnel and vehicle collision avoidance devices configured to be used in collision avoidance systems are disclosed. The collision avoidance devices are configured to be aware of the context (e.g. position, location, state, status, etc.) in which the person or vehicle is. This awareness allows the devices to avoid transmitting non-hazardous proximity warnings when the context does not warrant the transmission of proximity warnings, and to transmit special critical proximity warnings when the context warrants the transmission of such proximity warnings. To detect the context, the devices comprise one or more context-awareness mechanisms (e.g. user input interfaces, sensors, infra-red receivers, etc.), each of which being capable of detecting one or more particular contexts. A collision avoidance system comprising these personnel and vehicle collision avoidance devices is also presented.

主权项

1) A collision avoidance device comprising:
a) a processing unit; b) a transceiver comprising an antenna, the transceiver being in communication with the processing unit and being capable of establishing wireless communications with other collision avoidance devices in communication range to transmit and/or receive proximity warnings; c) a user interface in communication with the processing unit; d) at least one context awareness mechanism in communication with the processing unit, the at least one context awareness mechanism being configured to detect a context in which the collision avoidance device is and to transmit data related to the detected context to the processing unit; wherein the processing unit is operable to 1) disable the transmission of proximity warnings to at least some devices if the processing unit determines that the detected context is non-hazardous, 2) cause the transmission of regular proximity warnings to at least some devices if the processing unit determines that the detected context is hazardous, or 3) cause the transmission of critical proximity warnings, different from regular proximity warnings, to at least some devices if the processing unit determines that the detected context is critically hazardous. wherein the collision avoidance device being integrated into a cap lamp
