A device designed for the removal, storage, and installation of removable hardtops from convertible sport utility vehicles, either from the rear or side, comprising a wheeled base unit, a vertical support structure and a top clamping assembly, wherein the base unit is aligned below the top frame and the vertical support structure connects them together, wherein the device can be disassembled for simple shipping, is adjustable for height and depth to accommodate different SUV models, and includes markers for easy assembly.

A device for lifting a metal cover may include a rope having a first end and a second end and a magnet connected to the first end of the rope. The magnet may be configured to be applied to a manhole cover, and upon applying an upward force to the second end of the rope, the magnet pulls the manhole cover upward.

Presented herein are removable pull tabs that are configured to be detachably coupled to pluggable modules in a manner that facilitates removal of the pull tabs from the module without disassembling the modules. In particular, a removable pull tab may comprise a handle, first and second substantially parallel attachment arms extending from the handle, and a reinforcement line embedded in the handle and first and second attachment arms. The first and second attachment arms comprise first and second attachment mechanisms, respectively, disposed at a distal end of the respective attachment arm. The first and second attachment mechanisms are configured to detachably couple to first and second apertures, respectively, of a pluggable module.

The support mechanisms of the present invention comprise a vessel supported by suspension cables suspended from trollies that can move along the length (longitudinal) of a framework. The support system is such that waste material, even upon heating, cooling, etc., can constantly and smoothly move through the entire system, with the vessel generally being in a natural, balanced orientation.

Systems, methods, and apparatuses for engaging, lifting, and moving objects such as wheeled cargo trailers are provided. In one embodiment, a mobile apparatus includes a transport mechanism, a frame, and one or more lift assemblies. The lift assemblies may be adjusted using one or more attached actuators that position the lift assemblies and/or components thereof for engaging and lifting an object. The transport mechanism may be autonomously operated. A vision system may be used to locate and identify objects and/or guide the mobile apparatus into position to engage and lift the objects. An adapter for a pneumatic braking system of a wheeled cargo trailer is also provided. The adapter provides a pneumatic attachment for a pressurized air source that is separate from a glad hands connector attached to the braking system.

An unmanned aerial vehicle according to certain embodiments generally includes a chassis, a power supply mounted to the chassis, a control system operable to receive power from the power supply, at least one rotor operable to generate lift under control of the control system, and a winch mounted to the chassis. The winch includes a reel and a motor. The reel has a line wound thereon, the line having a free end. The reel includes a circumferential channel in which a wound portion of the line is wound onto the reel. The circumferential channel includes an inner portion, an outer portion, and a passage connecting the inner portion and the outer portion. The motor is operable to rotate the reel under control of the control system to thereby cause the line to wind onto and off of the reel, thereby causing the free end of the line to raise and lower.

An unmanned aerial vehicle according to certain embodiments generally includes a chassis, a control system, and at least one rotor. The chassis includes a first battery compartment configured to receive sliding insertion of a first battery, and a second battery compartment configured to receive sliding insertion of a second battery. The control system is operable to receive power from the first battery and the second battery when the first battery is received in the first battery compartment and the second battery is received in the second battery compartment. The at least one rotor is operable to generate lift under control of the control system when both the first battery and the second battery are installed to the chassis. The control system is configured to remain at least partially active under power supplied by the first battery when the second battery is removed from the second battery compartment.

A method according to certain embodiments generally involves operating a system including an unmanned aerial vehicle (UAV) and a base station. The base station includes a nest including an upper opening having an upper opening diameter and a lower opening having a lower opening diameter less than the upper opening diameter. The lower opening is accessible from within the base station. The method generally includes landing the UAV within the nest such that a portion of the UAV is accessible via the lower opening, releasably attaching a load to the UAV, and operating the UAV to deliver the load to a destination.

An example carriage is configured for mounting to an unmanned aerial vehicle. The carriage generally includes a housing assembly configured for mounting to the unmanned aerial vehicle, a movable grip mounted to the housing assembly for movement between a capturing position and a releasing position, a latch device, and a driver. The latch device has a latching state and an unlatching state, is configured to retain the movable grip in the capturing position when the latch device is in the latching state, and is configured to permit movement of the movable grip from the capturing position to the releasing position when in the unlatching state. The driver is operable to transition the latch device from the latching state to the unlatching state.
