Abstract: Tents and canopies are ubiquitous for outdoor recreation and gatherings. Tents and canopies are poorly lit, especially during night time. Camping lights such as lanterns are ineffective for lighting the entire space of a tent or canopy. To address these issues, a lighting apparatus can improve the quality of lighting inside a tent or a canopy by lighting a tent using a plurality of flexible strips having lighting elements thereon and providing a housing enclosing a lighting controller circuit for controlling the lighting elements. The flexible strips are electrically coupled to the lighting controller and extends away from the lighting controller. The housing can be hung inside, near the top center point of the tent or canopy to illuminate not only the area inside the tent or canopy, but also the tent or canopy itself. The lighting apparatus has a unique physical design suited for tents, canopies, and automobiles.

Abstract: A system for identifying an animal comprises an identification tag/transponder device surgically implanted into tissue of the animal and a scanning unit. As the animal passes in a vicinity of a scanning unit, the system causes the identification device to send a signal to a receiving portion of the scanning unit, and processes the signal, and identifies the animal from the signal. The system is of particular benefit to veterinary surgeries in assisting their smooth operation.
