Abstract: Systems and methods of electronic document handling permit organizations to comply with legal or regulatory requirements, electronic discovery and legal hold requirements, and/or other business requirements. The systems described provide a unified approach to data management that enables compliance, legal and IT personnel to focus efforts on, e.g., a single data repository. The systems permit users to define and utilize information governance policies that help automate and systematize different compliance tasks. In some examples, organizations may push data in any third-party data format to the systems described herein. The systems may permit compliance or IT personnel to detect when a legally sensitive production file has been changed or deleted. The systems may also provide a unified dashboard user interface. From a dashboard interface, users may perform searches, participate in collaborative data management workflows, obtain data management reports, and adjust policies.

Abstract: A power adaptor for a computer discovers the power environment when it is plugged into a socket and sends a signal to the computer along the power line indicating the environment, so that the computer can configure operations accordingly.

Abstract: A portable computer searches for preprogrammed wireless stations when it boots, and if it does not recognize any, stops booting the O.S. so that data cannot be accessed. In this way, should the portable computer be stolen and removed from its intended vicinity, data on the computer cannot be accessed by the thief.
