Abstract:
Some embodiments are directed to an unmanned vehicle for use with a companion unmanned vehicle. The unmanned vehicle includes a position unit that is configured to determine a current position of the unmanned vehicle. The unmanned vehicle includes a memory unit that is configured to store a planned path of the unmanned vehicle. The unmanned vehicle includes a control unit that is configured to determine that the unmanned vehicle is off-course based on the current position of the unmanned vehicle and the planned path assigned to the unmanned vehicle, generate a delay and a corrected path for the unmanned vehicle, and communicate the delay and the corrected path to the companion unmanned vehicle. The control unit is further configured to control a movement of the unmanned vehicle along the corrected path after the delay.
Abstract:
Methods, systems, and computer-readable media are described herein for simulating a view of a horizon at night. The positions of a number of light sources may be determined from the perspective of a viewer location. A number of light attributes associated with the light sources are determined. A horizon view visualization is provided that includes a number of light representations corresponding with the light sources. The light representations are depicted according to the determined positions and light attributes.
Abstract:
A method performed by a first rolling stock, comprising: receiving one or more communications from one or more second rolling stock, with a railroad network comprising the first rolling stock and the one or more second rolling stock; executing, by the first rolling stock, one or more of a local rule and a global rule; determining, based on executing, a speed for the first rolling stock relative to a speed of at least one of the one or more second rolling stock; and controlling the speed for the first rolling stock in accordance with the determined speed, wherein controlling promotes avoidance of a collision between the first rolling stock and the at least one of the one or more second rolling stock.

Abstract:
A non-transitory processor-readable medium storing code causes a processor at a first vehicle (e.g., a first autonomous vehicle) to generate a first planned path based on a current position of the first vehicle and a mission requirement assigned to the first vehicle. A first planned path associated with a second vehicle (e.g., a second autonomous vehicle), which is based on a current position of the second vehicle and a mission requirement assigned to the second vehicle, is received at the first vehicle. After the first planned path associated with the second vehicle is received, a second planned path is generated based on the first planned path associated with the second vehicle and at least one of the mission requirement assigned to the first vehicle or the first planned path of the first vehicle. The second planned path of the first vehicle is transmitted to the second vehicle.
Abstract:
Vehicles and other objects (4a, 4b, 4c, 5, 6, 7, 8) in a surface mine (1) are equipped with monitoring devices (12) that communicate by radio in order to detect the risk of collisions. The devices (12) are equipped with GNSS-receivers (15). At least one of the objects (4a, 4b, 4c) has two devices (12a, 12b) mounted to it. Each of the two devices (12a, 12b) determines its position independently, which in turn allows to determine not only the position, but also the orientation, of the object.
Abstract:
An apparatus and method is provided for avoiding collisions by detecting multiple targets and making an alert. The apparatus has transmit and receive functions. The transmitter transmits signals that are processed by PDMA protocol. The receiver detects a plurality of targets based on the PDMA protocol to determine a hazardous situation. Multi trails, such as operators of vehicles with the apparatus can be aware that there is another trail or a quick vehicle by alert and avoid collisions in a severe environment.
Abstract:
Some embodiments are directed to an unmanned vehicle for transmitting signals. The unmanned vehicle includes a transmitting unit that is configured to transmit a signal towards an object. The unmanned vehicle also includes a control unit that is in communication with at least one companion unmanned vehicle. The control unit is configured to determine a position of the at least one companion unmanned vehicle relative to the unmanned vehicle. The control unit is further configured to control the transmitting element based on at least the position of the at least one unmanned vehicle such that the transmitting element forms a phased-array transmitter with a transmitting element of the at least one companion unnamed vehicle, the phased-array transmitter emitting a transmission beam in a predetermined direction.
Abstract:
A computer implemented method of real-time condition monitoring of UMVs, the method including the steps of: receiving, in a control centre computer processing system, unmanned vehicle (UMV) condition data from a UMV; receiving, in the control centre computer processing system, UMV condition data from a network of condition-sensing UMV tracking stations: comparing, in the control centre computer processing system, the condition data from the UMV and the condition-sensing UMV tracking stations; and instructing, by the control centre computer processing system, the UMV to take an action in response to the comparison of condition data.
Abstract:
A method is provided for automatically detecting an obstacle from a moving vehicle using a planar sensor mounted on the vehicle. The method includes the steps of: (a) receiving data at a computer system from the sensor, said data comprising a series of points defied by a planar coordinate system relative to the sensor where the sensor detected a return during a frame, and receiving data at the computer system indicating the vehicle's geo-referenced location and orientation; (b) identifying, by the computer system, an obstacle candidate profile from the series of points; (c) transforming, by the computer system, the obstacle candidate profile from a sensor-relative representation to a geo-referenced representation; (d) repeating steps (a) to (c) for a given number of frames; and (e) detecting, by the computer system, an obstacle when the obstacle candidate profiles in the geo-referenced representation for each of the given number of frames substantially coincide.
