Utility
Electronic distance meter and method of determining a distance with an electronic distance meter
29 Nov 22
An electronic distance meter comprises a coupler located between a laser source and a target and adapted to divert a portion of measurement light emitted by the laser source into a calibration portion connected to a photodetector and comprising an attenuator between said coupler and said photodetector for varying the luminance value of the light passing through the calibration portion, said calibration portion having a known length and said processor being configured to perform distance measurements through the calibration portion at a variety of luminance values achieved by said attenuator to derive calibration values from said distance measurements and said known length, said processor being further configured to use said calibration values for determining a target distance based on a return pulse signal.

Utility
Area Coverage Planner with Replenishment Planner
24 Nov 22
A method of area coverage planning with replenishment planning includes receiving information of a boundary of the work area, location information of one or more refill stations, and information of a current amount of the material left in the autonomous vehicle, laying a plurality of tracks within the boundary of the work area so as to minimize a total distance of the plurality of tracks, generating a coverage trajectory, and based on (i) the coverage trajectory, (ii) the location information of the one or more refill stations, (iii) the current amount of the material left in the autonomous vehicle, and (iv) a nominal full amount and a nominal consumption rate of the material by the autonomous vehicle, determining one or more logistic points along the coverage trajectory at which a remaining amount of the material reaches a threshold, for each logistic point, generating a replenishment trajectory.
