Abstract: A modular patella trial system and method is provided. A modular patella trial includes an articular element and at least one sizing element. The articular element has a length, a width, and a thickness. The articular element has a posterior and anterior surfaces separated by their thickness. The anterior surface has protrusions extending outwardly. Any of the sizing elements have a length, width, and thickness. Any such sizing elements have posterior and anterior surfaces separated by their thickness. At least one aperture extends through the posterior and anterior surfaces of the sizing elements. Such apertures are capable of receiving a corresponding protrusion of the articular element. The modular patella trial has a thickness substantially equal to the total of the thicknesses of the articular element and the sizing elements used in conjunction with the articular element.

Abstract: A system and method for digital space estate management and content distribution is described. This system and method is comprised of an allotted number of time slots of fixed or variable duration, which are analyzed as digital space estates and devoted to content distribution. This system is configured to provide a web service portal which allows users to view available digital space estates, and either purchase them for a fixed price or variable price by proposing a higher acquisition offer amount than potential other users who have submitted offers on the same digital space estate. The system is further configured to utilize attributes of time slots and digital display nodes to recommend time slots to users. The system is configured to allow users to resell acquired digital space estates to other users.
