Abstract: A peristaltic pump for pumping a liquid, such as a juice concentrate, includes a rotor assembly attached to a housing, a band attached to the housing and surrounding at least a portion of the rotor assembly A tube is positionable between the band and the rotor assembly. The position of the band can be adjusted relative to the rotor assembly to adjust the pressure applied to the tube by the band and the rotor assembly. The rotor assembly includes rollers therein for pumping concentrate from a reservoir by drawing a vacuum.

Abstract: The present invention relates to the system, apparatus, and method for controllably mixing a concentrate with a dilution substance using closed-loop feedback in order to improve the resultant substance. The present invention discloses a system, apparatus and method for sensing the conductivity of a diluted substance to provide feedback information for adjusting dispensing of a concentrate used to produce the resultant or diluted substance. The present invention also includes a system for dispensing beverages using the conductivity sensor such that the system controllably adjusts the dispensing of concentrate to maintain the resultant beverage within a desired concentration range based on conductivity sensing. The present invention also includes the method for sensing the conductivity of the resultant beverage and adjusting the dispensing of concentrate in response to the conductivity of the resultant beverage. The invention includes a conductivity sensor coupled to a dispensing portion downstream of the introduction of concentrate into the dilution liquid. The conductivity of the resultant mixed beverage is measured and the dispensing of the coffee concentrate is adjusted to maintain the resultant beverage within a desired conductivity range.

Abstract: Apparatus for measuring the electrical conductivity of a subject comprises a coil for producing a substantially uniform magnetic field within a predetermined volume and a transport assembly for causing relative movement between the subject and the predetermined volume so as to move at least portions of the subject into and out of the volume. A measuring circuit is coupled with the coil for measuring the electrical conductivity thereacross and a control circuit causes the measuring circuit to measure the electrical conductivity across the coil a plurality of times during movement of the subject relative to the volume so as to obtain a plurality of measurements of the electrical conductivity across the coil with different portions of the subject within the volume. A method for measuring the electrical conductivity of a subject comprises producing a substantially uniform magnetic field within a predetermined volume; causing relative movement between said subject and said predetermined volume so as to move at least portions of said subject into and out of said volume; measuring the electrical conductivity across said magnetic field a plurality of times during movement of said subject relative to said volume so as to obtain a plurality of measurements of the electrical conductivity across said magnetic field with different portions of said subject within said volume.
