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.

Methods are described that perform a dispatched consumer-to-store return or swap logistics operation for an item being replaced using a modular autonomous bot apparatus assembly and a dispatch server. The method begins with receiving a return operation dispatch command that includes identifier information, transport parameters, and designated pickup information for the item being replaced/returned, along with authentication information related to an authorized supplier of the item being replaced. Modular components of the bot apparatus are verified to be compatible with the dispatched logistics operation. The MAM then autonomously causes the bot apparatus to move to the designated pickup location, notifies the authorized supplier of an approaching pickup, receives supplier authorization input to permissively allow access to a payload area within the bot apparatus, monitors loading as the item being replaced is received along with return documentation, and then autonomously causes movement of the bot apparatus back to the origin location.

A containment basin comprising a plurality of interlocking modular panels, wherein said modular panel are free-standing. The interlocking modular panel for use in a containment basin, comprise: a base section; and a side section; wherein said base section panel and side section panel being fixedly connected to one another at an edge and comprising a plurality of rib elements bridging the side section and base section.

This disclosure provides a container wallboard module and a container. The container wallboard module includes a wallboard body and two side columns. The side columns deviate from two ends of the wallboard body in a length direction. The wallboard body is provided with assembly holes for detachable connection with other wallboard modules. The side column includes a column riser body and two connecting ends respectively formed at upper and lower ends of the column riser body. The connecting ends protrude from the column riser body in a front-back direction, and the connecting end is provided with a connecting hole for detachable connection with other wallboard modules. The container includes two side wall modules, a roof panel module, a bottom plate module, a front wall module and a rear wall module, all of which are detachably connected. The side columns, a top gusset and a bottom gusset form a column frame.

According to a first aspect of the present application, a self-cleaning sectional panel tank is provided. The tank comprises at least one side wall for joining other side walls in forming the sectional panel tank. The at least one side wall comprises: a first unit panel having a first extension at its edge for supporting the first unit panel; and a second unit panel having a second extension at its edge. The first unit panel and the second unit panel are joined together contiguously at the first extension and the second extension by at least one fastener; and at least one directional sprinkler nozzle connected to the at least one side wall configured to discharge a cleaning and/or disinfectant solution onto interior surfaces of the self-cleaning sectional panel tank.

A modular door assembly is provided and includes a storage container and a modular door. The storage container includes a body defining an interior storage space, a door opening positioned at a door end of the body that is communication with the interior storage space, and a pair of container doors each secured to the door end of the body by a container door hinge. The container doors are movable between a container closed position to cover the door opening and a container open position allowing access therein. The modular door is removably attachable to the door end of the body and closes the door opening with the container doors in the open position.

Methods perform one or more dispatched medical logistics operations using a modular autonomous bot apparatus assembly and a dispatch server where the operations are related to a diagnosis kit for treating a patient. The MAM of the bot receives a dispatch command, verifies compatibility of the bot assembly with the dispatched operation(s), receives a diagnosis kit in the CSS, has the MAM autonomously causing the MB to move to a destination location while notifying the authorized delivery recipient for the diagnosis kit of the approaching delivery. With appropriate authentication input received, the MAM coordinates with the CSS to provide access to the kit, monitor unloading of the kit, provide instructional information on use of the kit, and autonomously cause the MB to return to the original location with a return item related to the diagnosis kit with notification to personnel at the medical entity about the return item.

A liquid containment structure such as a frac pond has a perimeter wall; a floor liner bounded by the perimeter wall; and a platform underneath the floor liner, the platform formed of a plurality of mats laid edge to edge and whose upper faces collectively define a support surface. Related methods of use of the structure include installing the structure at a well site, and in some cases using the structure as a frac water pond. A drain channel may be defined in the support surface below a portion of the floor liner, with the portion of the floor liner extending downward into the drain channel.

A gasket arrangement (122) for providing a substantially fluid-tight seal between at least two corresponding mating surfaces (120), comprising a first member (124) and a second member (126), the second member (126) being arranged at least in part to provide a fluid-tight seal about the first member (124); wherein the second member (126) is capable of deforming the first member (124) while maintaining the fluid-tight seal when compressed.
