Abstract: Systems and techniques for personalized assessment and/or learning are provided. The system may select tasks and task content for a user consistent with an administrator's suggested learning regimen for the user, while also adapting the selection of tasks and task content based on the user's performance and/or context when the user is not being supervised by an administrator.

Abstract: A touchless interactive display system includes a display with a display area bounding the display. A reflective surface is located along an edge of the display. One optical sensor opposes and faces the reflective surface so that the optical sensor has a primary, non-reflected field of view and a secondary, reflected field of view that is reflected back from the reflective surface. The primary field of view covers a first portion of the display area that is less than the whole display area, and the reflected field of view covers a second portion of the display area, such that the first and second portions of the display area cover the entire display area. The optical sensor and a processor are operable to detect an object placed within at least one of its first and second fields of view without having the object touch the display.

Abstract: A fixed display system that can interact with a communication device includes a display system including a fixed display operable to display information. A sensor is operable to provide a first signature upon an occurrence of a predetermined event, and the communication device is also operable to provide a second signature upon the occurrence of the same predetermined event. A processor compares the first and second signatures and determines whether these first and second signatures describe the same predetermined event, whereupon the processor initiates a communication session between the display system and the communication device. In addition, personal information of the user on the communication device may be used locally or partially/fully transferred to the display system to provide a personalized interactive experience for the user.

Abstract: A system and method for estimating the position of wireless devices within a wireless communication network combines measured RF channel characteristics for the wireless device with one or more predicted performance lookup tables, each of which correlates an RF channel characteristic to some higher order network performance metric and/or a position within an environmental model. Measured RF channel characteristics for wireless devices are compared against the performance lookup tables to determine the sent of lookup tables that most closely match the measured RF channel characteristics. The positions within the environmental model corresponding to the selected set of matching lookup tables are identified as possible locations for the wireless device. The performance lookup tables are uniquely constructed by site-specific location, technology, wireless standard, and equipment types, and/or the current operating state of the communications network.

Abstract: The apparatus includes a memory for storing representations of a microcellular transmitter and a macrocellular transmitter. The representation of the microcellular transmitter is configured to transmit a representation of a first signal, the representation of the macrocellular transmitter is configured to transmit a representation of a second signal. A database is responsive to the memory. The database has a plurality of data structures, and the plurality of data structures comprise a map of a geographic area. A predetermined location is positioned on the map. A facet having a size and comprising at least three points defining a plane is associated with the predetermined location. First and second instruction sets are available to calculate a characteristic of the first and second signals. A processor responsive to the memory and the database uses one of the first instruction set and the second instruction set to calculate the characteristic at the predetermined location.
