摘要： A parasitically-coupled dual-band patch antenna is described. The antenna includes an inner conductor having one or more feed holes. The antenna also includes an outer conductor surrounding the inner conductor in a radial direction. The antenna further includes one or more feeds each having a vertical portion that passes through the feed holes and a horizontal portion that extends in an outward direction from the feed holes toward the outer conductor. The feeds are conductively connected to the outer conductor. The horizontal portion of each of the feeds is separated from and is conductively disconnected from a top surface of the inner conductor.

摘要： A method of area coverage planning for an autonomous vehicle includes, at a computer system, receiving information of a boundary of a work area, and laying a plurality of tracks within the boundary of the work area. The plurality of tracks is spaced apart from each other by a spacing. Laying the plurality of tracks includes, based on the information of the boundary of the work area, performing a multivariate optimization to: (i) determine an optimal direction of the plurality of tracks, and (ii) an optimal offset for a first track from the boundary, so as to minimize a total distance of the plurality of tracks. The method further includes generating a trajectory that is traversable by the autonomous vehicle to traverse the plurality of tracks.

摘要： A movable accessory for an automatic point layout system includes a laser receiver and an array of LEDs. Two laser controllers aim vertical laser light planes toward any desired point on the jobsite. The user moves the accessory into a first laser light plane, thereby impacting a photosensor on the laser receiver. The accessory's electronic controller translates that laser light impact and illuminates a corresponding LED in a first color. The user then moves the accessory into a second laser light plane, thereby impacting a photosensor on the laser receiver. The accessory's electronic controller translates that impact and illuminates a corresponding LED in a second, different color. The user then moves the accessory until the two LED colors intersect. When the intersect occurs, the accessory's electronic controller translates these impacts and illuminates a corresponding LED in a third, different color.

摘要： Some embodiments of the invention relate to methods carried out by an NSS receiver and/or a processing entity capable of receiving data therefrom, for estimating parameters derived from NSS signals useful to determine a position, and for generating protection level(s) for an application relying on NSS observations to produce an estimate of said parameters. A float solution is computed using NSS signals observed by the NSS receiver. A best integer ambiguity combination that minimizes an error norm is identified based on the float solution. Additional integer ambiguity combinations are identified, which have the smallest error norms that, together with the error norm of the best integer ambiguity combination, jointly satisfy the integrity risk. A measure of spread of the best and additional integer ambiguity combinations is computed. The protection level(s) is then generated from the measure of spread. Systems and computer programs are also disclosed. Some embodiments may for example be used for safety-critical applications such as highly-automated driving and autonomous driving.

摘要： A system for integrating high-density laser scanner data with mixed-reality is disclosed. In some implementations, the system may acquire, using a laser scanner, a collection of data points representing a three-dimensional point cloud, wherein the laser scanner includes: a laser configured to generate an optical beam; a beam-steering device configured to steer the optical beam; and a detector configured to receive light from the optical beam, after light from the optical beam is reflected from an object in an environment. The system may transmit data of the point cloud to the augmented-reality device, wherein the augmented-reality device comprises: one or more cameras configured to acquire images of the environment; and a display configured to render graphics on the display. The system may align a reference frame of the augmented-reality device to the data of the point cloud. The system may present a graphic on the display of the augmented-reality device, wherein the graphic is positioned on the display in relation to the environment based on the reference frame of the augmented-reality device being aligned to data of the point cloud.
