Abstract: The present invention provides a method and apparatus for deterring pets or other animals from biting or chewing into medication containers. In some embodiments, the invention consists of two or more conductive metal sheets or strips in layers around the side of the container, which are wired to complete a circuit when pressed by the force of an animal's bite or touched by an animal's tongue. In some embodiments, the sheets or strips are spaced or held apart so that a normal human grip would not have sufficient force to complete the circuit. In some embodiments, the device slides onto the medication container with a friction fit, and is removable for use on future containers. In some embodiments, the circuit includes a battery-powered alarm to deter the animal. In other embodiments, the circuit delivers a mild electrical shock to the animal's mouth or tongue through the metal strips or sheets.

Abstract: Computerized systems and methods for sharing identified cyber-threat information in a standardized and secure format. The sharing of cyber-threat information assists in preventing malicious actors from replicating successful cyber-attacks by informing potential targets of the methods employed by the malicious actors, and the defensive measures that those targets should to implement to prevent those methods from succeeding. By distributing cyber-threat information in a standardized format, the systems and methods enable participating entities to automatically analyze and implement defensive measures for cyber-threat information shared by any other participating entities. The systems and methods also permit an entity to control which threat information it shares and which other entities it shares it with in a secure manner in order to preserve that entity's security and reputation.
