Abstract: A personal defense device and method incorporating Bluetooth technology into a container with an irritant agent, such as pepper spray. The container is provided with Bluetooth-enabled wireless communication circuit that allows generation of an alarm signal every time pepper spray is dispensed. The alarm signal is capable of being received by a cellular telephone and capable of generating a predetermined responsive action by the cellular telephone, such as activation of a speakerphone, dialing of an emergency number, and activation of a global positioning system locator. A panic actuator is optionally provided on the container; the panic actuator is independently connected to the wireless communication circuit to generate the alarm signal even if the pepper spray is not dispensed.

Abstract: A device and method for executing self-defense using non-lethal form of weaponry provides for the use of capsaicinoids-containing repellant admixed with a solid marking agent. The marking agent contains material not soluble in water. The marking agent can be glitter particles having particle size of between 50 microns and 3000 microns. A canister containing pepper spray and the glitter particles can be carried by law enforcement personnel or civilians. Once the repellant agent is dispensed it deposits on the skin and clothing of a suspect, making it easier to identify the suspect.

Abstract: A card holder for building a three-dimensional structure from rectangular planar cards is disclosed. The card holder has an elongated body with a center part and a plurality of ribs radiating from the center part. Adjoining ribs form card-receiving V-shaped channels for securing edges of the cards when constructing a house or tower of cards.
