The present invention provides an adaptive process control and profit depiction system which is responsive to both process measurement input signals, economic inputs, and physical environment inputs. The process control system features an interactive optimization modeling system for determining manipulated process variables (also known as setpoints). These manipulated process variables are used to position mechanisms which control attributes of a manufacturing system, such as a valve controlling the temperature of a coolant or a valve controlling the flow rate in a steam line.

A computerized model provides a display of a physical environment in which a communications network is or will be installed. The communications network is comprised of several components, each of which are selected by the design engineer and which are represented in the display. Errors in the selection of certain selected components for the communications network are identified by their attributes or frequency characteristics as well as by their interconnection compatibility for a particular design.

Disclosed are methods and apparatus for implementing a reality overlay device. A reality overlay device captures information that is pertinent to physical surroundings with respect to a device, the information including at least one of visual information or audio information. The reality overlay device may transmit at least a portion of the captured information to a second device. For instance, the reality overlay device may transmit at least a portion of the captured information to a server via the Internet, where the server is capable of identifying an appropriate virtual billboard. The reality overlay device may then receive overlay information for use in generating a transparent overlay via the reality overlay device. The transparent overlay is then superimposed via the device using the overlay information, wherein the transparent overlay provides one or more transparent images that are pertinent to the physical surroundings. Specifically, one or more of the transparent images may operate as “virtual billboards.” Similarly, a portable device such as a cell phone may automatically receive a virtual billboard when the portable device enters an area within a specified distance from an associated establishment.

The present invention is directed to a system and method for tracking objects, such as customers in a retail environment. The invention is divided into two distinct software subsystems, the Customer Tracking system and the Track Analysis system. The Customer Tracking System tracks individuals through multiple cameras and reports various types of information regarding the tracking function, such as location by time and real world coordinates. The Track Analysis system converts individual tracks to reportable actions. Inputs to the Customer Tracking System are a set of analog or digital cameras that are positioned to view some physical environment. The output of the Customer Tracking System is a set of customer tracks that contain time and position information that describe the path that an individual took through the environment being monitored. The Track Analysis System reads the set of customer tracks produced by the tracking system and interprets the activities of individuals based on user defined regions of interest (ROI). Examples of a region of interest are: (1) a teller station in a bank branch, (2) a check-out lane in a retail store, (3) an aisle in a retail store, and the like.
