Tablet dispenser with isolated delivery sensor
First Claim
1. A proof of delivery system for use with a solid product dispenser, comprising:
- a) an outlet conduit being light transmissive and including an interior surface and an exterior surface, the interior surface being exposed to humid conditions; and
b) a sensor mechanism proximate the exterior surface of the outlet conduit, the sensor mechanism sensing delivery of a solid product through the outlet conduit, the outlet conduit providing a barrier to the humid conditions thereby protecting the sensor mechanism from exposure to the humid conditions.

Abstract
A preferred embodiment proof of delivery system for use with a solid product dispenser includes an outlet conduit and a sensor mechanism. The outlet conduit is light transmissive and includes an interior surface and an exterior surface. The interior surface is exposed to humid conditions. The sensor mechanism is proximate the exterior surface of the outlet conduit, and the sensor mechanism senses delivery of a solid product through the outlet conduit. The outlet conduit provides a barrier to the humid conditions thereby protecting the sensor mechanism from exposure to the humid conditions.

7. A proof of delivery system for use with a solid product dispenser, comprising:
-
a) an outlet conduit being light transmissive; and
b) a light sensor mechanism including an emitter emitting a beam and a receiver receiving the beam, the emitter being positioned on one side of the outlet conduit and the receiver being positioned on an opposite side of the outlet conduit, the emitter emitting the beam and the receiver receiving the beam through the outlet conduit, the outlet conduit protecting the light sensor mechanism from contamination by residue within the outlet conduit. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A proof of delivery system for use with a solid product tablet dispenser, comprising:
-
a) a product tablet;
b) an outlet conduit through which the product tablet is dispensed, the outlet conduit being light transmissive; and
c) an infrared sensor mechanism including an emitter emitting a beam and a receiver receiving the beam, the emitter being positioned on one side of the outlet conduit and the receiver being positioned on an opposite side of the outlet conduit, the emitter emitting the beam and the receiver receiving the beam through the outlet conduit, the outlet conduit protecting the infrared sensor mechanism from contamination by residue within the outlet conduit, wherein as the product tablet is dispensed through the outlet conduit, the product tablet interrupts the beam within the outlet conduit, and the infrared sensor mechanism provides indication that the product tablet has been dispensed. - View Dependent Claims (16, 17, 18, 19, 20, 21)
