Abstract: Disclosed modular animal collar systems include a D ring exoskeleton system, a breakaway latch tongue system and other systems. Disclosed collars may be self-orienting. Disclosed collars include auto release systems to ensure that collars do not choke or otherwise injure a pet. Collars include sophisticated electronics to commutate with a pet owner's smart phone but also include means of communication not requiring the use of a smart phone. Collars may include a base collar containing a micro controller and other computer related components. Surrounding modular components may contain additional equipment and may be added as needed by a pet owner. Disclosed collar functions are executed by the disclosed collars and facilitate the retrieval, care and training of a pet.

Abstract: An ultraviolet (UV) detector for detecting and verifying the authenticity of documents placed therein and exposed to ultraviolet light and ambient (white light) backlighting. The UV detector includes a detector housing, and a viewing chamber having a viewing mirror mounted therein for viewing documents. The detector housing also includes a document insertion slot for inserting documents into the viewing chamber adjacent to the viewing mirror. The detector housing further includes an LED holder for holding one or more LED's therein to provide a source of UV light in the viewing chamber which is transmitted to the viewing mirror and to the documents for identifying UV activated features on the documents, including UV holographic images and/or UV activated inks on the documents that are illuminated. The user looks into the viewing chamber for viewing the UV activated features on the viewing mirror.
