Abstract: An item dispensing device having a wheel with a dispensing bucket formed into the wheel wall. The device can have a number of features to prevent items being dispensed from interlocking and thereby preventing further dispensing. These features can include protrusions on the cylinder wall, and a torsion spring to agitate the items to be dispensed, and a reed sweeper to help prevent jamming of an item during dispensing. Further, the device includes an ejection arm having an ejection face configured to dispense items in a manner that are engaging for a pet.

Abstract: Blood glucose levels in an individual are determined by aligning a region of the retina of the eye of an individual with an instrument, measuring a regeneration rate of the retinal visual pigment of the individual, and using the measured regeneration rate to calculate the blood glucose level. The apparatus for measuring the blood glucose comprises a blood glucose analysis instrument adapted to determine blood glucose concentration from information regarding regeneration rate of the visual pigment in the retina region of an eye, and an alignment mechanism adapted to align the retina region with at least a portion of the device.
