A sectional panel tank comprises one or more side wads that are joined together in forming the sectional panel tank. One of the side wall comprises a first unit panel having a first extension at a first edge of the first unit panel and a second unit panel having a second extension at a second edge of the second unit panel. By combing the second extension to the second extension, the second unit panel is joined to the first unit panel for providing a continuous surface of the side wall. No gasket is needed between the first extension and the second extension. A method of making the sectional panel tank is also disclosed. A method of making prefabricated unit panels with lining sheets is further disclosed for the sectional panel tank.

Methods and enhanced apparatus used in such methods are described that a dispatched logistics operation for a deliverable item from a hold-at-location (HAL) logistics facility having a secured storage and using a modular autonomous bot apparatus assembly and a dispatch server. The bot apparatus assembly picks up and delivers the item from the HAL facility in response to a delivery dispatch command from the dispatch server. In response, the MAM of the bot verifies compatibility of modular components for the operation, controls receiving of the deliverable item from the secured storage at the HAL facility, then autonomously causes movement to the delivery destination. The MAM notifies the customer before delivery of the approaching delivery, authenticates delivery is to the authorized customer, provides access to the item within the bot apparatus assembly, monitors unloading of the item, then autonomously moves back to the HAL facility.

A main body for a carrying box includes first and second side walls, and a pair of first connection walls and a pair of second connection walls that are pivotally hinged to opposite ends of the first and second side walls and are pivotally hinged to each other. The main body further includes a latch assembly having a bracket and a latch disposed at the first and second side walls, respectively. When the first and second connection walls pivot, a distance between the first and second side walls is reduced and a volume of the main body is reduced. The bracket is automatically fastened to the latch as the bracket and the latch are pressed toward each other.

What is disclosed is an assembly system to create customizable, mobile, lightweight containers and container-like products ranging in size from consumer and commercial storage products to shipping containers and small mobile buildings. The system uses slidable interconnection of various profile shapes of elongated panel modules with same length standardized linear and corner panel connectors, to create container sleeves retained by customizable end framing to become container shells. The container shells are customized to size needed by the number of interconnected panel modules used and the length to which they are cut. Assembly of their few basic parts is simple with a limited range of tools and skills needed. The system further provides for simple, seamless, solid and reversible structural attachment of third party components, without welding or riveting, to achieve specific customization goals as needed. Finally, the system provides for easy and scar free disassembly for shipping, storage reconfiguration, or recycling.

A container includes a first contoured edge of a first wall panel, a second contoured edge of a second wall panel, and a spline with a first channel that receives the first contoured edge and a second channel that receives the second contoured edge to form a spline joint securing the first and second wall panels together. The first and second channels are symmetrical with openings in opposite directions

A plastic article useful as a riser for a septic tank or as a water tank article is comprised of a multiplicity of plastic rings which are attached vertically to each other at joints. Ring pairs which alternately have inward and outward sloping conical walls nest within each other for shipment or storage. A lid is shaped for use with the topmost ring to cover the opening irrespective of which conical shape the ring has.

In an exemplary embodiment, a modular secondary containment unit is adapted to surround an above-ground fluid storage tank and includes a plurality of corner assemblies. Two or more components of each of the corner assemblies are composed of one or more reinforced resin composite materials. In several exemplary embodiments, the modular secondary containment units and the above-ground fluid storage tanks are used in oil and gas exploration and production operations. In an exemplary embodiment, an assembly for a modular secondary containment unit includes a track segment including first and second channels, a wall segment mounted on the track segment and extending within the first channel of the track segment, and a brace engaged with the wall segment and extending within the second channel of the track segment. In an exemplary embodiment, a method of constructing a modular secondary containment unit is provided.

A modular mobility base for a modular autonomous bot apparatus transporting an item being shipped including a mobile base platform, a component alignment interface, a mobility controller, a propulsion and steering system, and sensors. The component alignment interface provides an alignment channel into which another modular component can be placed and secured on the platform. The mobility controller generates propulsion control signals for controlling speed of the modular mobility base and steering control signals for navigation of the modular mobility base. The propulsion system is connected to the platform and responsive to the propulsion control signal. The steering system is connected to the mobile base platform and is responsive to the steering control signal to cause changes to directional movement of the modular mobility base. The sensors are disposed on the platform provide feedback sensor data to the mobility controller about a condition of the modular mobility base.

A detachable modular mobile autonomy module (MAM) for a modular autonomous bot apparatus includes a housing with latching points, an autonomous controller, location circuitry, external sensors monitoring an environment external to the MAM and providing sensor data to the controller, multi-element light panels on the housing driven by the controller; and a modular component power and data bus. The bus has a bottom side modular component electronics interface disposed on the housing that mates to a corresponding interface on another proximately-attached modular component of the bot. The MAM receives sensor data from the external sensors, receives outside sensor data from additional sensors disposed on a mobility unit of the bot, generates steering and propulsion control output signals based on location data from the location circuitry, external sensor data, mobility unit sensor data, and destination information data maintained by the controller, and generates transport and delivery information for the light panels.

Methods are described that perform a dispatched inventory operation related to an inventory item within a modular autonomous bot apparatus assembly and a dispatch server. modular mobile autonomy control module (MAM) receives an inventory dispatch command from the dispatch server and a modular cargo storage system (CSS) receives the inventory item at an inventory hub location. The MAM autonomously causes the assembly to then move to a remote business facility as a destination location, receive authentication input from an authorized delivery recipient, coordinates with the CSS to provide selective access to the inventory item, detects when the inventory item has been removed from within the CSS, and autonomously causes the assembly to move on a return route back to the inventory hub location after removal of the inventory item.
