Present embodiments relate to a revolving mailbox cluster and central package delivery system. More specifically, without limitation, present embodiments relate to a revolving mailbox cluster that includes: substantially circular layers stacked vertically, where a second layer sits atop a first layer, and wherein each substantially circular layers includes: vertically opposed bottom top plates, divider plates perpendicular to the bottom and top plates, and a center ring, where the bottom and top plates, dividers, and center ring define individual mailbox units, each of which has an opening disposed opposite the center ring; a first motor for moving the substantially circular layers vertically; and a second motor for rotating the substantially circular layers.

A parcel box includes an external shell and upper and lower baffles. The external shell includes left and right side walls, a front wall, a rear wall, a base, a cover and a door. Each of the cover and the door are movable between closed and opened positions, respectively. When opened, the cover facilitates access by parcels through a top opening and into a storage area. When opened, the door facilitates removal of parcels from the storage area and through a bottom opening. The upper baffles are pivotally coupled to the front wall, independently movable about an upper common pivot axis between deployed positions and depressed positions, and independently spring-biased toward the deployed positions. The lower baffles are pivotally coupled to the rear wall, independently movable about a lower common pivot axis between deployed positions and depressed positions, and independently spring-biased toward the deployed positions.

A delivery door extension that attaches to an existing door jamb and engages with an existing door is provided. The delivery door extension includes a panel having a planar body with opposing front and rear surfaces extending between first and second side surfaces, a top surface, and a bottom surface, wherein the panel body includes an opening. The delivery door extension also includes a delivery window body configured to move between an open position and a closed position, a hinge mechanism attached to the first side surface of the panel, a blocking mechanism on the second side surface that restricts movement of the existing door, and a frame that includes first and second portions.

A retractable arm device, system, and method with a locking mechanism for preventing items placed in a device or receptacle from getting stuck, damaged, or torn. The retractable arm includes an inner tube, a pawl, and an outer tube surrounding the inner tube. The inner tube slides within the outer tube and the pawl preventing the retractable arm from moving into an extended position under particular conditions. The retractable arm may be placed in a receptacle for items to prevent the door from being reopened before the door is fully closed.

A locker system for delivering heat sensitive products comprising a plurality of lockable compartments including at least one refrigerated lockable compartment, a control unit for controlling said plurality of lockable compartments, a cooling device comprising an expansion chamber receiving liquid CO.sub.2 from a reserve of liquid CO.sub.2 and delivering gaseous CO.sub.2 in each of said refrigerated lockable compartments through at least one common duct, and an extraction system to avoid excessive concentration of CO.sub.2 in a building where the locker system is located.

Method and its enabling device for remote wireless micro-latching for security purposes, comprising at least one user or controller, one mobile communication device, and one secured device, whereas said user is enabled to open or close a micro-latch in said a secured device, for instant a safe box or a medical cabinet, allowing access to secured content, including money, ID card, checks, as well as medicine. Also disclosed is a multiplicity of said devices and their preprogrammed remote control by computer or mobile app. The micro-latching can be amplified to macro-latching, for instance by a micro-solenoid switching a high power electrical switch bank or relay, which in turn initiates industrial processes.
