An exemplary dispenser includes a housing and a refill unit. The refill unit being removable and replaceable. The dispenser also includes a processor, memory, a dose count stored in memory that is indicative of the number of doses in a full refill unit, a level sensor for detecting a predetermined level the refill unit and a dispense count indicative of the number doses of product dispensed from the refill unit. In addition, the dispenser includes memory and has logic stored in the memory for recalibrating the number of doses remaining in the refill unit as a function of the dose count, the number of doses of product dispensed and the predetermined level of product. The number of doses of product remaining in the refill unit may be displayed on the dispenser, on a remote station, or on both the dispenser and a remote station.

A dispenser having a projector is disclosed. The projector has a body with a cavity sized and shaped to receive a battery, a lens holders sized and shaped to receive at least one lens for focusing an image, a first protrusion sized and shaped to be received by a first wall of the dispenser, and a second protrusion sized and shaped to be received by a second wall of the dispenser. The projector further includes a lens assembly, a lamp, and a circuit board. The lens assembly is disposed in the lens holder, the lamp is configured to project a light through the lens assembly, and the circuit board is in electrical communication with the lamp.

A hand operated device for storing, measuring, and dispensing powder or granular materials, with a simplified structure and reduced number of parts. The housing integrates a material storage container with a dispenser, comprising: special compartments and sound damper, made of elastic porous material that makes use of the device quiet; a one touch assembly and disassembly of an inner space of the device where the dispenser is located; structural elements for dispensing a predetermined volume of the material or its fraction, including a way to reduce the length of the working stroke of the dispensing mechanism; wall extensions to prevent bridges of sticky particles forming; separating walls to allow delivery a more than one material stored in one device including more than one material transporting mechanisms inside the dispenser; and structural elements providing exact measuring, and sifting or pouting of the materials.
