Abstract: An animal training device is configured to encourage an animal with a clicking sound and a gelatinous reward. The animal training device has a housing, joined to a housing end cap at a housing first end and a dispenser head at a housing second end. A dowel rod is arranged within the housing and through a dispensing lever. A push bar is arranged within the housing and joined to the dispensing lever with a drive plate and a first compressor spring; wherein the push bar further comprises a push bar first end and a push bar second end. A tube is fit over the end cap and accommodates the gelatinous reward. Depressing the dispensing lever moves the drive plate and thus the push bar, pushing the gelatinous reward through the dispenser head.

Abstract: An apparatus for directing light to an eye for exciting a photosensitizer includes a high output or super bright LED and an optic that receives light from the LED and concentrates the light so that it is nearly collimated. The LED is a single light source that is used for both therapy and for diagnostics or aiming.
