There is presented a reliable technique for measuring condition change in nonlinear data such as brain waves. The nonlinear data is filtered and discretized into windowed data sets. The system dynamics within each data set is represented by a sequence of connected phase-space points, and for each data set a distribution function is derived. New metrics are introduced that evaluate the distance between distribution functions. The metrics are properly renormalized to provide robust and sensitive relative measures of condition change. As an example, these measures can be used on EEG data, to provide timely discrimination between normal, preseizure, seizure, and post-seizure states in epileptic patients. Apparatus utilizing hardware or software to perform the method and provide an indicative output is also disclosed.

The detection of devices with duplicate media access controller (MAC) addresses in a cable network. A cable modem (CM) having a MAC address is connected by the cable network to a cable modem termination system (CMTS) having a gateway interface address. A centralized storage of historical cable modem MAC address / giaddr pair data is used to identify cable modems (CM's) that report duplicate MAC addresses. A server tracks the CM MAC address / giaddr pair data of all CM requests that it receives and stores the MAC address / giaddr pair data into a datastore (such as a database). When a CM seeks to access the network, the server looks into the datastore to determine whether the CM MAC address of the CM has previously been stored with a different associated giaddr, which would imply that there are multiple CMs attached to different CMTSs where the CMs share the same MAC address. If such duplication is detected, a appropriate remedial response is taken.

Described are collection view objects, which provide a user interface view over a data collection, where each view may have its own sort order, filter and / or grouping criteria, as well as current item semantics. A user interface element is bound to a data collection, such as via markup language (e.g., XAML). At runtime, a collection view object is instantiated as an indirection between the data collection and the user interface element, whereby a collection of data items is viewed according to how each collection view object is currently configured with respect to sorting, filtering and / or grouping. Multiple collection views may be specified on the same data collection, whereby distinct simultaneous views of the data items may be presented in different user interface elements. The collection view object dynamically updates the displayed data as changes are made in the data collection. A current item may be selected within the collection view.
