Abstract: An image may be obtained from one or more cameras coupled to a first vehicle. The image may be provided as input to a machine learning algorithm configured to determine whether an object depicted in the image corresponds to another vehicle and to determine size information and location information for the object. Output from the machine learning algorithm enables obtaining features including size and location information for a second vehicle that is identified in the image. The features may be used to determine whether the second vehicle is depicted within a predetermined region of the image including a predicted travel path of the first vehicle. The features may also be used to determine whether the second vehicle is within a predetermined proximity of the first vehicle. Thereafter, a determination may be generated as to whether there is a significant risk of collision between the first vehicle and the second vehicle.

Abstract: Methods, apparatuses and computer programs are disclosed for estimating, or at least for generating information usable to estimate, the heading of at least one axis of interest of a rigid body. Rigid body is equipped with an antenna of a navigation satellite system (NSS) receiver, and with sensor equipment comprising sensors such as a gyroscope, an angle sensor, and accelerometers, depending on the form of the invention. Rigid body is subject to a known motion comprising causing a point's horizontal position to change, the point being referred to as “point B”, while keeping another point's position, the point being referred to as “point A”, fixed relative to the Earth. Considering the motion constraint, an estimation of the heading is generated using sensor equipment data and NSS receiver data. The estimation of the heading may for example be used to estimate the position of any point of rigid body.

Abstract: An automatic point layout system identifies points and their coordinates using vertical planes of laser light. Laser controllers aim vertical laser light planes that will cross at any desired point on the jobsite floor. The user views a virtual jobsite illustration on a remote controller touchscreen display, and selects a point of interest. Commands are sent to the two laser controllers, which aim their laser transmitters at that point of interest, showing visible laser light lines that intersect directly at the point of interest, for staking. The user selects a second point of interest on the touchscreen display, commanding the laser transmitters to rotate to a new set of coordinates. The user performs these functions seamlessly; the remote controller allows the user to quickly move from one point of interest to the next, without having changing to any other operating mode between the identifying and staking of each new point.

Some solutions feature the integration of real-time, high-rate global navigation satellite system (“GNSS”) displacement information with acceleration and/or velocity data within a single device to create very high-rate displacement records. The mating of these two instruments allows the creation of a new, very high-rate displacement measurement device that has the full-scale displacement characteristics of GNSS and high-precision dynamic motions of seismic technologies. Such a device can be used for earthquake early warning studies and other mission critical applications, such as volcano monitoring, building, bridge and dam monitoring systems.

Abstract: The invention relates to a method carried out by a navigation satellite system (NSS) receiver or a processing entity receiving data therefrom, for estimating parameters useful to determine a position. The NSS receiver observes NSS signals from NSS satellites over multiple epochs. A first filter, called “timely estimator”, and second filter, called “precise estimator” and delayed with respect to the timely estimator, are operated. The estimators use state variables, and make use of NSS signals observed by the NSS receiver or information derived therefrom. The precise estimator further computes its state variable values based on observations that are not derived from NSS signals observed by the NSS receiver. The values of some of the state variables computed by the timely estimator are recurrently replaced by values from the precise estimator. A corresponding system is also disclosed.
