Abstract: A invisible radio frequency (RF) leash system is provided for controlling and confining an owner's dog to a predefined distance or radius. The system comprises a radio frequency (RF) smartphone hardware interface or dongle, electronic dog collar module, and mobile device application user interface. The system RF hardware preferably operates on the 433 MHz, 2.4 GHz, or other radio frequencies. The dog owner sets the distance and stimulus modality via the mobile device application and is provided with automatic correction when the dog reaches the perimeter boundary and the dog is confined to the perimeter. The RF hardware interface or dongle is comprised of radio hardware for distance ranging, data-link, and receiving information from the dog collar module. The dog collar tracks activity and location with a GPS module and transmits RF distance ranging signals, location, and activity data to the RF dongle for display on the owner's mobile device application.

Abstract: An invisible leash electronic dog collar system and mobile device user interface for training a pet dog to stay within a user-defined space, distance or radius from the user, or predetermined home space or local area map. Additional configuration settings and functionality is provided through a mobile device or smartphone application based user interface. An electronic dog collar or collar attachment is provided for the dog with electrical, vibrational, mechanical, and audible stimulus modalities. A mobile device or smartphone based application is provided for the dog owner to configure and adjust settings and functionality of the dog collar.
