The interface card 325 may be a removable card or, alternatively, it may be affixed inside the upper portion 210 of the beverage tower 100. It will be understood that the interface card 325 may also be affixed to the front of the upper portion 210 of the beverage tower 100 rather than being situated inside the upper portion 210. If the interface card 325 is inserted inside the upper portion 210 of the beverage tower 100, it may be viewed and accessed through an upper portion opening 330 situated in the front of the upper portion 210. The interface card 325 may provide indicia identifying the various flavor syrups and/or beverages available for dispensing from the beverage tower 100, the available size selections, other user selectable options, as well as marketing indicia. The indicia may be printed on the interface card 325 and/or may be at least partially formed integrally into the interface card 325. The flavor syrups and/or beverages corresponding to that shown on the interface card 325 may be programmed into the interface and control cassette 320, as explained in greater detail below. When desired, such as when the flavors provided by the beverage tower 100 are changed and/or the control logic of the interface and control cassette 320'is changed, a different interface card 325 may be inserted into the . beverage tower 100. For example, the interface card 325 may be changed as the selection of flavor shots and beverages dispensed by the beverage tower 100 changes. It will be understood by those of skill in the art that the interface card 325 and the interface and control cassette 320 maybe .distinct components as shown in FIG. 3 or, alternatively, some or all of the aspects of one of the components may be incorporated into the other component. For example, the ability to display available flavor shots and beverages may be incorporated into the interface and control cassette 320 by providing a touch screen display on the interface and control cassette 320 from which a user can both view and select available flavor shots and beverages. As another example, the interface card 325 may be disposed remote from the interface and control cassette 320 but include the ability to receive user input and transmit any received user input to the interface and control cassette 320. The interface card 325 may be configured to receive user input by incorporating suitable user input devices into the interface card 325 such as, for example, push buttons, contact switches, mouse and/or keyboard, touch screen displays, or capacitive resistance input devices.

The input tubing 230 may be coupled to the flow control block 310 of the beverage tower 100. More specifically, each tube of the input tubing 230 may be coupled to an associated or corresponding orifice or valve 405 of the flow control block 310. An orificeor valve 405 may be provided for each flavor syrup 105 or water 110 provided to the flow control block 310. The flow rate may be individually controlled for each flavor syrup 105 or water 110 by the orifice or valve 405. Additionally, the flow rate for each flavor syrup 105 or water 110 may be set so that it remains constant for each flavor syrup 105 or water 110. It will be understood that the flow control block 310 may be any suitable device for regulating the flow of one or more liquids. It will also be understood that the one or more orifices or valves 405 of the flow control block 310 may be situated or positioned in a staggered or offset array, thereby requiring relatively little space and, consequently, at least partially contributing to a relatively small footprint for the beverage tower 100. The orifices or valves 405 of the flow control block 310 maybe constructed from any suitable materials such as, for example, plastic, rubber, or a combination of plastic and rubber. The flow control block 310 may also be constructed from any number of suitable materials such as, for example, plastics, rubber, acrylics, metals, polymers, synthetic materials, OT a combination of any such materials. When a flavor syrup 105 or water 110 exits the flow control block 310, it may then be transported to the solenoid block 315 by solenoid input tubing 415. The solenoid input tubing 415, which may or may not be insulated, may be any tubing suitable for transporting a liquid from the flow control block 310 to the solenoid block 315 such as, for example, rubber or plastic tubing. The solenoid input tubing 415 may be terminated at the edges of the solenoid block 315, as explained in greater detail below. Alternatively, the solenoid input tubing 415 may further extend into the solenoid block 315 to one of more solenoids 410 included within the solenoid block 315. One or more suitable devices such as, for example, pins, staples, or braces, may secure the solenoid input tubing 415 in place at the solenoid block 315, Although the flow control block 310 and the solenoid block 315 are depicted as two separate and distinct components of the beverage tower 100, it will be understood that the flow control block 310 and the solenoid block 315 may be integrally formed as a single component of the beverage tower 100, The solenoid block 315 may include one or more solenoids 410 that control a gate in the flow path of a flavor syrup 105 and/or water 110 through the solenoid block 315. A solenoid 410 may be provided for each flavor syrup 105 and for water 110. When' a solenoid 410 is actuated or opened, a flavor syrup 105 or water 110 may be allowed to flow past the solenoid 410 and through the solenoid block 315 and then exit into output tubing 420, which carries the flavor syrup 105 or water 110 to the nozzle block 402, where it can be dispensed by the beverage tower 100. The interface and control cassette 320 may control the actuation of the various solenoids 410 of the solenoid block 315 based on user input, thereby allowing a user of the beverage tower 100 to select a flavor syrup 105 or beverage for dispense from the beverage tower. 100. The control signal from the interface and control cassette 320 may be provided to the solenoids 410 via the solenoid wires 425, which may be any type of wire suitable for communicating an electrical signal to the solenoids 410. The solenoid block 315 may form a centralized manifold for the array of solenoids 410. Use of a single block such as, for example, an acrylic block may decrease leak points and help maintain steady flow rates and pressure drops across the solenoid array. An acrylic block may also be easily machined and, if a clear acrylic block is utilized, the clear acrylic block may allow for increased visibility of the internal components of the solenoid block 315, thereby providing for easier trouble shooting of the solenoid block 315. A plurality of solenoids 410 maybe laid out in a staggered array in the solenoid block 315, as illustrated. The staggered array may be a unique arrangement of the solenoids 410 that requires relatively little space, and, consequently, at least partially contributes to a relatively small footprint for the beverage tower 100. In the illustrative embodiment, the solenoid block 315 may be an acrylic block to which the plurality of solenoids 410 are attached, but it will be understood by those skilled in the art that many materials besides acrylic can be used to construct the solenoid block 315, Each solenoid 410 may include a coil of wire encased in a housing with a moving plunger or shaft. When electricity is applied to the coil of a solenoid 410, the resulting magnetic field may attract the plunger, and pull it into the solenoid body, allowing flavor syrup 105 or water 110 to pass through the solenoid 410. When electricity is removed, the solenoid plunger may return to its original position via a return spring or gravity, preventing the flow of a flavor syrup 105 or water 110 through the solenoid 410. It will be understood by those of skill in the art that a variety of different solenoids could be utilized in the present invention including, but not limited to, AC solenoids, DC solenoids, linear open frame solenoids, linear tubular solenoids, rotary solenoids, or variable positioning solenoids. Each solenoid 410 in the solenoid block 315 maybe any suitable solenoid such as, for example, a ST-021 solenoid manufactured by KIP, Inc. When a flavor syrup 105 or water 110 enters the solenoid block 315 through the solenoid input tubing 415, the flavor syrup 105 or water 110 may flow to the one or more solenoids 410 via input channels 412 (FIG. 4B) integrated into the solenoid block 315. It will be appreciated that the solenoid input tubing 415 may extend into the solenoid block 315 as an alternative to integrating input channels 412 into the solenoid block 315. Electricity may be applied to the one or more solenoids 410 by way of the •solenoid electric wires 425, actuating the plunger to allow the flavor syrup 105 or water 110 to flow past the individual solenoid 410 into output channels 414 {FIG. 4B) integrated into the solenoid block 315 and then into output tubing 420, which may then carry the flavor syrap 105 or water 110 to the nozzle block 402. Electricity may be applied according to the control logic of the beverage tower 100, as will be explained in greater detail below. As shown in FIG. 4A, the output tubing 420 may terminate at the edge of the solenoid block 315; however, it will be appreciated that the output tubing 420 may extend into the solenoid block 315 as an alternative to integrating output channels 414 into the solenoid block 315. The output tubing 420 may or may not be insulated and may further be any tubing suitable for transporting a liquid from the solenoid block 315 to the nozzle block 402 such as, for example, rubber or plastic tubing. One or more suitable devices such as, for example, pins, staples, or braces, may secure the output tubing 420 in place as it passes from the solenoid block 315 to the nozzle block 402. FIG. 4B is a cross-sectional view of a solenoid 410 situated in a solenoid block 315 utilized by a beverage tower 100, according to an illustrative embodiment of the present invention. The solenoid block 315 may include input channels 412 and output channels 414 for each solenoid 410. The input channels 412 may be connected to the solenoid input tubing 415 and the output channels 414 may be connected to the output tubing 420 at the edges of the solenoid block 315. The solenoid 410 is situated operationally opposite the input and output channels 412, 414 so that its plunger 430 may block the flow of a flavor syrup 105 or water 110 passing through the solenoid block 315, as described above. The solenoid 410 may be screwed via a threaded portion 435 into the solenoid block 315; however, it will be understood that a solenoid 410 may be attached to the solenoid block 315 in a variety of other ways such as, for example, by a bonding material, adhesive material, or by magnetic force. The plunger 430 may make contact with a solenoid chamber contact point 440 when the solenoid 410 is not actuated, thereby blocking a flavor syrup 105 or water 110 from passing through the solenoid block 315. The bottom of the plunger 430 and/or the top of the solenoid chamber contact point 440 may be comprised of an elastic material such as, for example, rubber. The elastic material may assist in forming a seal between the plunger 430 and the solenoid chamber contact point 440 when the solenoid 410 is not actuated to prevent any undesirable leakage. When a solenoid 410 is actuated, the solenoid plunger 430 may recoil so that it no longer makes contact with the solenoid chambeT contact point 440, and a flavor syrup 105 or water 110 may be permitted to flow from the input channel 412 to the output channel 414 and out of the solenoid block 315 at the flow rate defined by the corresponding valve 405 of the flow control block 310. According to an aspect of the present invention, the input channel 412 and/or the output channel 414 may include a bend 445. The bend(s) 445 may be situated in the channels 412,414 within the solenoid block 315. Additionally, the bend(s) of the input and output channels 412, 414 may be formed with gradual turns thereby helping to maintain constant pressure across the solenoid 410 and to avoid unwanted pressure drops in the solenoid block 315. It will be understood that many different slopes or gradients may be utilized for the bend(s) 440 such as, for example, a slope of approximately ninety degrees. With reference back to FIG. 4A, when a flavor shot 105 or water 110 exits the solenoid block 315, it may pass through the output tubing 420 to the nozzle block 402. From the nozzle block 402, the flavor shot 105 or water 110 may be dispensed by the beverage tower 100. The flavor shot 105 or water 110 may be dispensed by a nozzle 505 (FIGS. 5A-5D) included in the nozzle block 402, as will.be explained in greater detail below with reference to FIGS. 5A-5D. After being dispensed by the nozzle block 402, the flavor shot 105 or water 110 may pass through a nozzle cap 240. The nozzle cap 240 may assist in directing the flow of the dispensed flavor syrup 105 or water 110, thereby assisting in the prevention of splash, splatter, and/or overspray by the nozzle block 402. FIG. 5A is a front view of a nozzle block 402 utilized by a beverage tower 100, according to an illustrative embodiment of the present invention. The nozzle block 402 may be made of acrylic or any other suitable material such as, for example, plastic. As shown in FIG. 5B, the nozzle block 402 may be made of a clear acrylic. An acrylic block may also be easily machined and, if a clear acrylic block is utilized, the clear acrylic block may allow for increased visibility of the internal components of the solenoid block 315, thereby providing for easier trouble shooting of the solenoid block 315. A nozzle cap 240 and a nozzle 505 may be removably or permanently affixed or connected to the nozzle block 402. The nozzle 505 and the nozzle cap 240 have been removed from the nozzle block 402 in FIG. 5A. The nozzle 505 may be permanently affixed to the nozzle block 402 or incorporated into the nozzle block 402. Alternatively, the nozzle 505 may include a threaded portion that may be screwed or twisted into a corresponding threaded portion vrithin the nozzle block 402, thereby allowing the nozzle 505 to be removably attached to the nozzle block 402. It will be understood that a variety of other means may be utilized to permanently or removably attach the nozzle 505 to the nozzle block 402 such as, for example, screws, bolts, or adhesive. The inside of the nozzle-cap 240 may contain tabs (not shown) that may fit into corresponding grooves 510 on the nozzle 505 or nozzle block 402, thereby allowing the nozzle cap 240 to be removably attached to the nozzle 505 or • nozzle block 402. The nozzle cap 240 may be detached or removed from the nozzle block 402 in order to assist in the performance of maintenance on the nozzle block 402, nozzle 505 and the nozzle cap 240. It will be understood that the nozzle cap 240 may be connected in a variety of ways other than tabs and corresponding grooves. For example, the nozzle cap 240 may be connected to the nozzle block 402 or nozzle 505 by screws, snaps, corresponding threaded grooves, or an adhesive material. It will also be understood that the nozzle cap 240 may be permanently attached to the nozzle block 402 or nozzle 505. FIG. 5B is a bottom perspective view of a nozzle block 402 and nozzle 505 utilized by a beverage tower 100, according to an illustrative embodiment of the present invention. As shown in FIG. 5B, the nozzle block 402 may additionally include input receptacles 515 that receive or couple to the output tubing 420. Flow channels 517 may receive the flavor syrup 105 or water 110 from the input receptacles 515 and direct the flow of the flavor syrup 105 or water 110 to an output opening 518 (FIG. 5C) corresponding to an associated input opening 519 of the nozzle (FIG. 5C) positioned opposite and coupled to the output opening 518 of the nozzle block 402 when the nozzle 50S is securely coupled to the nozzle block 402. The nozzle 505 may additionally include flavor syrup injectors (or flavor shot dispensers) 520 and water injectors 525 (or water dispensers). The functionality of these components is described in greater detail below with reference to FIG. 5C. FIG. 5C is a cross-sectional view of a nozzle block 402 utilized by a beverage tower 100, according to an illustrative embodiment of the present invention. As shown in FIG. 5C, the input receptacles 515 may receive a flavor syrup 105 or water 110 from the output tubing 420, and the input receptacles 515 may then interface with the flow channels 517 that carry the flavor syrup 105 and water 110 through the nozzle block 402 to the nozzle 505. Additionally, the diameter of the input receptacles 515 may be greater than the diameter of the flow channels 517 to accommodate the coupling of the output tubing 425 to the nozzle block 402. This decrease in diameter of the flow channels 517 through the nozzle block 402 may increase by a desired amount the pressure of the transported flavor syrup 105 or water 110 at the point of dispense of the nozzle block 402. It will be understood that the decrease in diameter of the flow channels 517 through the nozzle block 402 may be many different values such as, for example, a decrease in the range of approximately twenty percent to approximately seventy percent Additionally, each of the flow channels 517 may include an output opening 518 at its distal end. The output opening 518 may be positioned at the interface of the nozzle block 402 and the nozzle 505. Additionally, each of the output openings 518 may be positioned opposite to and coupled to a corresponding input opening 519 of the nozzle 505. The input openings 519 may be positioned in the nozzle 505 at the interface of the nozzle 505 and the nozzle block 402. Each of the input openings 519 may additionally be incorporated into either a flavor syrup injector 520 or a water injector 525 of the nozzle 505, as explained in greater detail below. In operation, a flavor syrup 105 may flow from a flow channel 517 to a flavor syrup injector 520 via the output opening 518 of the flow channel 517 and the corresponding input opening 519 of the flavor syrup injector 520. Similarly, water 110 may flow from a flow channel 517 to a water injector 525 via the output opening 518 of the flow channel 517 and the corresponding input opening 519 of the water injector 525. In operation, when a flavor syrup 105, water 110, or blended beverage is dispensed by the beverage tower 100, it is dispensed through the nozzle 505. A flavor shot maybe a controlled dispense of a flavor syrup 105. Flavor shots may be dispensed from the nozzle 505 through one or more flavor syrup'injectors 520 situated in the center portion of the bottom of the nozzle 505, with each flavor syrup injector 520 opening along the bottom of the nozzle 505. A single flavor syrup injector 520 may be associated with each flavor syrup 105 supplied to the beverage tower 100 or, alternatively, each flavor syrup 105 may be dispensed through a plurality of flavor syrup injectors 520. Additionally, one or more of the flavor syrup injectors 520 may open at a slight angle towards the center point of the bottom of the nozzle 505, as explained in greater detail below. Water 110 may be dispensed from the nozzle 50S through a plurality of water injectors 525 situated in a ring around the flavor syrup injectors 520 on the bottom of the nozzle 505, as explained in greater detail below. Alternatively, the openings for the plurality of water injectors 525 maybe situated along the outer side wall of the nozzle 505, and the water injectors 525 may open at a slightly downward angle. As the water injectors 525 dispense water out of the side of the nozzle 505, the water flow may or may not be directed by the nozzle cap 240, as will be described in greater detail below. FIG. 5D shows the operation of the nozzle 505 and nozzle cap 240 of a beverage tower 100, according to an illustrative embodiment of the present invention. When a flavor shot is dispensed by the beverage tower 100, it may be dispensed from a flavor syrup injector 520 of the nozzle 505. The flavor syrup injector 520 may dispense the flavor shot from the bottom of the nozzle 505 at a slight angle 528 from a central longitudinal axis of the nozzle 505. Additionally, each of the flavor syrup injectors 520 may dispense flavor shots so that they pass through a focal point 530 that may be situated below, the nozzle 505 and/or the nozzle cap 240. Directing flavor shots at a single focal point 530 may help to minimize splash, splatter, and overspray. Additionally, it may provide for easier blending of the beverages dispensed from the beverage tower 100. It will be appreciated that many different values may be utilized for
