LIQUID DISPENSING WITH BLINK DETECTION

摘要

PROBLEM TO BE SOLVED: To provide a device for accurately and cleanly dispensing a liquid or mist into an eye.SOLUTION: A liquid dispensing device 100 includes one or more electronic sensors 101 to sense an open state or closed state of an eye 105. The one or more sensors 101 include an emitter 102 and a detector 103. The emitter 102 emits a beam 106 which reflects off a reflecting point 104 and back to the detector 103. A processor 109 may receive input from one or both of the emitter and the emitter 102 and the detector 103. Executable software causes the processor to be functional to calculate the amount of reflection of the beam 106.SELECTED DRAWING: Figure 1
