Patent attributes
A system for controlling prisoners and protecting security personnel or victims of domestic violence is disclosed. The system includes a first wearable device configured to be secured about an appendage of a person, and includes a GPS receiver module, an electroshock module and wireless receiver. A second wearable device is configured to be worn about an appendage of a person, and includes a GPS receiver module, a transmitter and activation switch. If the first wearable device is within a predefined radius of a second wearable device, activation of the activation switch causes the transmitter to send a signal to the receiver to activate the electroshock module. Additionally, the system may include a server that can selectively activate the electroshock module and display the location of the wearable devices on a map or floorplan.
