Abstract: Safety head wear for use for example in high risk activities such as sports and industrial purposes where protection from head injuries is required. Components are provided inserted between the liner and outer shell and consists of two parts; a pod and a foam or foam like surrogate or structure. The foam or foam like material is contained in the chamber and is positioned in such a way to create constant force between the surface of the shell and head. The device provides a method of managing compression force characteristics of the helmet around the head designed to decrease brain trauma resulting from high linear acceleration during impacts to the helmet.

Abstract: Disclosures of databases for secondary purposes is increasing rapidly and any identification of personal data may from a dataset of database can be detrimental. A re-identification risk metric is determined for the scenario where an intruder wishes to re-identify as many records as possible in a disclosed database, known as a marketer risk. The dataset can be analyzed to determine equivalence classes for variables in the dataset and one or more equivalence class sizes. The re-identification risk metric associated with the dataset can be determined using a modified log-linear model by measuring a goodness of fit measure generalized for each of the one or more equivalence class sizes.
