Abstract: A rear trailer hostler can be used to move a parked trailer without otherwise disengaging pneumatic brakes thereof. For example, the rear trailer hostler can lift the wheels of the trailer off of the ground, thereby allowing a front hostler to move the trailer without a gladhands connection to the trailer pneumatic lines. Alternatively, the rear trailer hostler can move the trailer independently. For example, the trailer can be parked atop the rear trailer hostler and disconnected from the truck. With the rear trailer hostler supporting the locked wheels and the landing gear, the trailer can be moved without requiring the pneumatic brakes to be disengaged. The rear trailer hostler can also provide one or more safety or convenience features, such as a bridging platform or a safety door stop.

Abstract: A metal fused deposition printer can use the thixotropic properties of a metal (e.g., alloy) to control the viscosity of the material being deposited. The viscosity of the metal can be controlled by shearing the metal before, during, or after the deposition process. Use of the thixotropic properties can allow the viscosity of the metal to be controlled independent of the temperature of the metal. This can allow for more precise control of the temperature differential between the layer being deposited and the substrate layer, for example, such that the temperatures are substantially the same.

Abstract: Systems and methods for autonomous sterilization of vehicles includes coded logic or processing instructions to determine (i) when sterilization should occur (or not occur), (ii) where sterilization should occur (or not occur), and/or (iii) how sterilization should occur (e.g., which method to use, how long to conduct, and/or which parameter values/settings to employ). The sterilization system may autonomously determine when it is safe to sterilize an environment/location and/or how such sterilization should be carried out. Autonomous sterilization systems and/or processes described herein may permit facilities and/or services to remain open and/or available at higher rates than current offline processes permit, thereby increasing availability.

Abstract: A system can have an electromagnetic radiation (EMR) detection and ranging (DAR) device, such as a LIDAR device. A shock mount can couple the EMR DAR device to a vehicle. The shock mount can isolate the EMR DAR device from impulse shocks experienced by the vehicle. An inertial measurement unit (IMU) can be coupled to the EMR DAR device or a first portion of the shock mount. The IMU can measure movement of the EMR DAR device. Alternatively or additionally, the EMR DAR can detect locations of a reference feature of the vehicle at different times and can use the detected locations to determine movement of the EMR DAR relative to the vehicle. Data of the EMR DAR device indicative of detected features can be adjusted based at least in part on the movement measured by the IMU.

Abstract: Battery powered quadrotors or drones have a limited operation time. To extend operation time, a powered tether can be used. This tether provides power to the drone allowing it to stay up indefinitely. Most tethered drones are captured to the base station. The tether can reel in and out as the drone moves, but the drone can't go higher or further than the maximum length of the tether. If the tether can be automatically disconnected, the drone could fly off for some remote mission, assuming the drone had an onboard power source such as rechargeable batteries. The present invention relates to a self-powered drone tether that comprises a rechargeable drone in flight which is referred to as the rechargeable drone, a drone that carries a powered tether which is referred to as the tether drone, a coupling mechanism between the rechargeable drone and the tether drone, and a base station with a powered tether and tether deployment system.

Abstract: An autonomous vehicle can comprise winter servicing equipment, such as a snowplow, salt spreader, etc. A controller can be supported by the vehicle and can be operatively coupled thereto. The controller can be configured to control the vehicle to autonomously move through an area along a planned route to effect servicing (e.g., snow removal or remediation) of the area. For example, the controller can be configured to discretize the area into a plurality of cells and to determine a quantity of snow in each cell. The route through the area can be planned by the controller based at least in part on simulated movements of the snow quantities in the cells.
