Techniques are provided to enable a controller in a mining vehicle to manage proximity detection sensors associated with removable battery assemblies. In some aspects, the controller determines that a current battery assembly currently connected to the mining vehicle will be disconnected from the mining vehicle, removes the at least one proximity detection sensor mounted to the current battery assembly from a set of proximity detection sensors associated with the mining vehicle, thereby generating an updated set of proximity detection sensors associated with the mining vehicle, determines that a new battery assembly is connected to the mining vehicle, and adds the at least one proximity detection sensor mounted to the new battery assembly to the updated set of proximity detection sensors associated with the mining vehicle, thereby generating a further updated set of proximity detection sensors associated with the mining vehicle.

VEHICLE AND METHOD FOR CORRECTING DISTANCE IN NON-LINE-OF-SIGHT SENSING OF A REMOTE OBJECT IN UNDERGROUND MINING
A method in a controller of a mining vehicle entails detecting a remote object, determining a distance between the mining vehicle and the remote object and determining that the remote object is not in a direct line of sight with respect to the mining vehicle. The method entails adjusting the determined distance using a compensation factor, thereby obtaining a compensated distance between the mining vehicle and the remote object. The method entails performing a collision avoidance action based on the compensated distance between the mining vehicle and the remote object.

VEHICLE, CAP LAMP SYSTEM AND METHODS FOR COLLISION AVOIDANCE
A vehicle includes a first sensor to sense a first beacon emitted by a first beacon-emitting device worn by a person. The vehicle includes a collision-avoidance processor that determines if the person is located in an unsafe location relative to the vehicle based on a first signal generated by the first sensor. The collision-avoidance processor controls the vehicle in response to determining that the person is located in the unsafe location. A second beacon-emitting device near a seat in the vehicle emits a second beacon detectable by a second sensor worn by the person when the person sits in the seat. The second beacon has lower power and less range than the first beacon. The second sensor generates a second sensor signal in response to sensing the second beacon when the person sits in the seat, the first beacon-emitting device being deactivated in response to the second sensor signal.

For measuring the weight of a mining vehicle there is received a first load signal from a strain sensor arrangement, indicative of a weight of the vehicle. A first orientation signal from an orientation sensor arrangement is indicative of a relative orientation of at least one load-carrying part of the vehicle. A first movement signal from a motion sensor arrangement is indicative of a movement of the vehicle as a whole. An end of an unloading event is determined us-ing at least said first orientation signal, and a following stand-still event is determined using at least said first movement signal. A tare value of said first load signal is determined at said stand-still event and used to represent the measured empty weight of the vehicle.
