Abstract: The invention comprises a personal data sharing system comprising an aggregator for aggregating data from a plurality of disparate sources and for categorising said aggregated data into discrete groups of data, a platform configured to enable the assignment of an access permission level for each one of said discrete groups of data by allowing the user to configure said access permission level or by automatically assigning said access permission level from a number of pre-determined access permission levels; said platform being further configured to permit access to a discrete group of data dependent upon said access permission level.

Abstract: An umbrella is provided including a lower tube, an upper tube slidably coupled with the lower tube and a slider assembly including a slider slidably mounted along the upper tube. Also included is a retractable assembly mounted on the upper tube and connected to the slider of the slider assembly. The retractable assembly has a raised orientation for deploying the retractable assembly and a lowered orientation for retracting the retractable assembly. Also included is a pneumatic extender connected to the slider of the slider assembly for forcing the same to the raised orientation. When the retractable assembly is retracted, the same forms a protective shell about the tubes.
