Abstract: An injection apparatus, including: a needle configured to be inserted into a tissue; a light source to deliver light to the tissue to generate reflected light; a detector to detect the reflected light from the tissue; a processor coupled to the detector and configured to: analyze the reflected light from the tissue to identify a tissue type associated with the reflected light, and provide an output to a user based on the identified tissue type.

Abstract: A field assembleable wildlife observation shelter having an assembled configuration as that of a naturally occurring environmental element is provided. The shelter, which is modular in design, includes a plurality of rigid wall forming panels. Each of the rigid wall forming panels of the plurality of rigid wall forming panels has perimeter edges, and an arcuate cross section. Opposing side perimeter edges of each of the rigid wall forming panels are adapted such that adjacently paired rigid wall forming panels are reversibly securable in furtherance of forming a wall for substantially surrounding a wildlife observer. The plurality of rigid wall forming wall panels are configurable so as to form a transportable stack, more particularly, to define a secured bundle.
