Abstract: A system includes a display and a processor coupled to the display. The processor determines a position of a vehicle relative to a road lane and causes the display to depict a set of position indicators to convey the position of the vehicle relative to the road lane. In one state, the set of position indicators include a plurality of empty shape outlines and at least one filled shape outline. The processor also determines a position of a hazard relative to the vehicle and causes the display to depict a set of hazard position indicators to convey the position of the hazard relative to the vehicle. In one state, the set of hazard position indicators include a plurality of empty shape outlines and at least one filled shape outline.

Abstract: A method includes a mobile device receiving data from a first beacon in a plurality of beacons, wherein the data indicates a plurality signals strengths of signals received by the first beacon from the other beacons in the plurality of beacons. The mobile device uses multivariable regression based on the data received from the first beacon and signal strengths of signals received by the mobile device from the other beacons in the plurality of beacons to determine distances from the mobile device to the beacons. The mobile device determines a location of the mobile device based on the determined distances.

Abstract: A method includes a mobile device traveling in a vehicle scanning for Bluetooth devices. When the mobile device detects a Bluetooth device, it then determines that the Bluetooth device is a work zone tag. The mobile device then issues a warning that indicates that the vehicle is near a work zone based on the work zone tag.

Abstract: A precision servo control system for a pneumatic actuator has a piston positionable over a stroke of the pneumatic actuator using a supply of pressurized gas. A brake and a sensor system are connected to the actuator and to the servo control system. The servo control system operates to initiate the forward thrust from the pressurized gas to move the piston along the stroke. When a braking point along the stroke is determined, the servo control system initiates a reverse thrust from the pressurized gas while maintaining the forward thrust and simultaneously begins to selectively apply the brake to stop the piston within a predetermined tolerance of a desired stopping position.

The precision servo control system is easily programmable in a manner similar to that of a control system for electrical actuators. The precision servo control system can maintain the predetermined tolerance even under changing loads, long stroke lengths or vertically oriented stroke directions.
