Abstract: For controlling operation of a light source, a method of associating a light source with an area for which the light source is positioned to provide lighting comprises: identifying, based on a determined physical position of a light source, one of a plurality of areas as the area for which the light source is positioned to provide lighting; identifying at least one desired lighting condition for the identified area; and controlling, using a processor, operation of the light source based on the identified at least one desired lighting condition for the identified area.

Abstract: Disclosed are instruments used in collecting fluid samples from a subject such as, for example, aqueous humor samples. The instrument involves a linear actuator that, when engaged by the user via a switch, causes a syringe held within the instrument to collect a defined amount of sample. Kits comprising the instrument as well as methods of using the instrument to collect fluid samples are also disclosed.
