RELATED APPLICATIONS 
       [0001]    This patent application claims the benefit of U.S. Provisional Patent Application No. 62/198,064 to Chawla et al., filed on Jul. 28, 2015, the content of which is incorporated herein by reference in its entirety. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to the field of beverage preparation. More particularly, the present invention relates to an automated device for making tea latte, which includes the capability to use pre-packaged pods containing tea leaves and spices for the preparation of tea latte. 
       BACKGROUND 
       [0003]    The problem the present invention addresses is automating the process by which tea latte is brewed and prepared. 
         [0004]    Tea latte is a combination of tea and milk. Masala chai (Indian spiced chai-tea latte) comprises water, milk, loose tea, various spices and sweetener. Spices used to make chai tea may include ginger, cardamom, pepper, cinnamon, mint, lemon grass, cloves, star anise, fennel seeds, saffron, nutmeg, coriander, basil, licorice, rose, etc. 
         [0005]    Tea latte is typically prepared through a manual process. It would be desirable to at least partially automate the process of preparing tea latte. The traditional manual preparation process for tea latte is a process whereby water and milk is boiled, either together or separately, and to which fresh tea leaves and spices are added. The tea is then allowed to brew by immersion for a selected period of time, after which the mixture is filtered and served. 
         [0006]    The obvious problem of the traditional manual process of preparing tea latte is the effort and attention needed to brew good quality tea latte and to do it in a consistent and repeatable way. Additionally, cleaning required significant effort, as the vessels used are not specifically designed for brewing tea latte. 
         [0007]    The current marketplace contains some devices that attempt to automate the process of creating tea latte. However these devices are almost always repurposed automated coffee brewing devices that have been repurposed in attempt to use them to brew tea latte. 
         [0008]    Problems with current automated solutions to brew tea latte include but are not limited to the following: 
         [0009]    (1) Current devices for brewing tea latte use flow-through brewing instead of immersion brewing, whereas immersion brewing is the optimal method for brewing tea-latte; 
         [0010]    (2) Current devices do not include automated methods for frothing fresh milk and adding it to the tea-spice mixture; 
         [0011]    (3) Current pod-based devices for brewing tea latte use dried milk powder not fresh milk; 
         [0012]    (4) Current pod-based devices for brewing tea latte use instant tea instead of tea leaves; 
         [0013]    (5) Current devices for brewing tea latte were originally designed for brewing coffee, which has different temperature and time requirement than those required for tea latte. 
         [0014]    In addition, while there are several current automated solutions U.S. Pat. No. 9,107,533, U.S. Pat. No. 8,733,234, and U.S. Pat. No. 7,669,517 that address sub-components of the problem for heating and frothing milk they differ from and are less efficient than the present invention in several important ways. 
         [0015]    U.S. Pat. No. 9,107,533 describes a standalone milk foamer with a magnetic frothing mechanism. A key different between U.S. Pat. No. 9,107,533 and the present invention is that the present invention uses a planar linkage instead of a protrusion linkage between the magnetic frothing drive mechanism and the frothing mechanism inside the carafe. This means that in U.S. Pat. No. 9,107,533 there is a hollow pin formed into the bottom of the carafe that must be aligned with a protrusion in the base of the frothing drive unit to properly function. This is because U.S. Pat. No. 9,107,533 relies on a diametric magnetic linkage to drive their frother, in which the frother driver fits within the inner diameter of the frother itself. Whereas in the present invention a planar magnetic linkage is utilized between frother and drive. Which means that there are no protrusions the need to be aligned for the frother to function properly. Rather a gross indexing feature consisting of a dish-shaped relief consisting of a slight ramp around the edges of the carafe is used to get the carafe closely enough aligned so that the magnets in the frother inside the carafe and the magnetic drive mechanism housed in the base can couple properly. The benefits of the method of the present invention is the operator does not need to align the carafe to the protrusion. It also allows a design that supports simply sliding or putting the carafe in place which the method of U.S. Pat. No. 9,107,533 does not support. Also the lack of protrusions in the present invention means the unit is easier to clean. 
         [0016]    Additionally, U.S. Pat. No. 9,107,533 describes a system where a cuff and stacked coil induction heater is utilized. This means that the carafe has to be lifted up and then dropped several inches into a recessed bucket for the induction heater to couple with the carafe properly. This contrasts with the present invention where the carafe is simply slid into place by the user and only drops down by itself a few millimeters into the shallow dish-shaped relief that the carafe sits in. 
         [0017]    Not only do these two improvements provide a distinct benefit to the ease of use but they also improve the ability to clean the unit. In the present invention there are no large protrusions that have to be cleaned around or deep vertical walls. Rather the present invention with a shallow dish-shaped relief that the carafe sits in, is free from any major interruptions to the surface. This means that it is easy to wipe clean. 
         [0018]    U.S. Pat. No. 8,733,234 describes a frother that uses steam to froth milk not a magnetic drive mechanism used by the present invention. Frother that use steam to froth milk usually require operator intervention, whereas the magnetic driven frother mechanism of the present invention is entirely automated. 
         [0019]    U.S. Pat. No. 7,669,517 describes a frother with a vertical axis that is offset from the median vertical axis. In contrast the present mechanism utilizes a frother with a centered vertical axis. This centered vertical axis of the present invention, allows the present invention to optimally use an induction heater, which to some extent relies on concentricity of the fields produced and the target to be heated for optimal efficiency. Additionally, the present invention in one embodiment of the present invention, is therefore free from mechanical constraints that would otherwise require the intentional reduction of the height of the vortex created during the milk frothing process. Therefore, the present has less constraints on vortex height than the invention described in U.S. Pat. No. 7,669,517. 
         [0020]    In summary, the problem of providing an automated device that automates the process of creating tea-latte in a way that mimics the quality and expertise of manual methods has not been solved. Thus, there is a need for a device that automates the process of creating high quality tea-latte in a repeatable way and makes cleaning and maintenance easier. 
       SUMMARY 
       [0021]    Embodiments of the present invention pertain to an apparatus and method that automates the way in which tea latte is made. 
         [0022]    The approach of the present invention is to automate the process and methods used to create high quality tea latte in a repeatable manner and reduce cleaning and maintenance tasks. The present invention is distinct from other current solutions in several important aspects. 
         [0023]    The present invention can brew tea latte using freshly brewed tea and fresh milk. The present invention is designed specifically for the brewing of tea latte and is not a re-purposed coffee maker as is the case for other current solutions. 
         [0024]    The present invention steeps tea via immersion in hot water, rather than the flow through method that is typical of other machines. 
         [0025]    Additionally, the present invention is designed to accept purpose-specific tea pods, containing loose tea and spices that will drop into the boiler, presenting a benefit for tea brewing over space-constrained flow through coffee pods. Only when loose tea is allowed an unconstrained space to open and bloom can high quality tea latte be achieved. Current solutions with space-constrained flow through coffee pods do not allow enough space for the tea to open and properly brew. 
         [0026]    Due to these reasons and others, no other current automated device can consistently produce fully flavored and high quality tea latte that can be achieved with the present invention. 
         [0027]    In one embodiment of the present invention, the automation of the manual methods and processes of an expert tea latte maker, is accomplished with a programmable microprocessor which controls the various device sensors and actuators based on custom developed software for the present invention. The microprocessor is at the heart of the device providing the automated control and monitoring of the brewing process. 
         [0028]    According to one embodiment of the present invention an apparatus includes a body, a removable first container for water for positioning on the body and a removable second container for milk for positioning on the body. An interface is positioned on the body to accept preparation parameters for tea latte from the user of the device. A boiler within the body receives water from the first container and milk from the second container. In one embodiment of the present invention a removable sieve is placed within the boiler for containing the tea and spices during the brewing process is inserted. In one embodiment of the present invention a single tubular heater adjacent to the boiler heats the water and the milk in accordance with at least one preparation parameter. In one embodiment of the present invention the boiler is a thin thermal vessel designed to decrease time to raise temperature and is therefore more energy efficient. In one embodiment of the present invention the power of the heater is controller by a PID or fuzzy logic controller with inputs from a thermistor embedded in the body of the boiler. A temperature sensor measures the temperature of the liquid inside the boiler. An electronically controlled valve controls the flow of the liquid from the boiler. A magnet activated frothing wheel is mounted to the body for frothing of milk and the final mixing of the brewed tea, spices and milk. In one embodiment of the present invention a microprocessor via the use of various sensors and actuators monitors and controls all actions of the sub-components within the present invention. In one embodiment of the present invention is the apparatus is designed to accept purpose-specific tea pods, containing loose tea and spices that will drop into the boiler, presenting a benefit for tea brewing over space-constrained flow through coffee pods. In one embodiment of the present invention, a Wi-Fi component is included within the apparatus for communication to external devices and systems such as mobile devices and the internet cloud. In one embodiment of the present invention the milk carafe is treated with a non-stick coating to aid in manual or automatic dishwashing. 
         [0029]    According to another embodiment of the present invention an apparatus includes a body, a removable first container for water for positioning on the body and a removable second container that is a combination milk carafe and boiler for positioning on the body. An interface is positioned on the body to accept preparation parameters for tea latte from the user of the device. Two boilers and heaters are contained within the body. The first boiler receives water from the first container. The second boiler receives milk from the second container. In one embodiment of the present invention a removable sieve is placed within the first boiler for containing the tea and spices during the brewing process is inserted. In one embodiment of the present invention two heaters are provided. The first heater is a tubular heater adjacent to the boiler that heats the water in accordance with at least one preparation parameter. The second heater is an induction heater adjacent to the boiler that heats the milk in accordance with at least one preparation parameter. In one embodiment of the present invention both boilers are thermally and otherwise functionally optimized for their individual tasks, and therefore require reduced heat up times compared to off the shelf vessels that are often used for brewing tea latte. In one embodiment of the present invention the power of the heater is controller by a PID or fuzzy logic controller with inputs from a thermistor embedded in the body of the boiler. A temperature sensor measures the temperature of the liquid inside the boiler. An electronically controlled valve controls the flow of the liquid from the boiler. In one embodiment of the present invention after the tea and spices have been brewed in the first boiler an electronically controlled valve controls their flow into the second boiler containing the milk. A magnetically driven or directly mechanically driven frothing wheel is mounted to the body under the second boiler for milk for the frothing of milk and the final mixing of the brewed and strained tea latte and milk. In one embodiment of the invention after the final brewing the brewed tea latte is drained through an electronically controlled valve into the milk container, from which it is then served. In one embodiment of the present invention a microprocessor via the use of various sensors and actuators monitors and controls all actions of the sub-components within the present invention. In one embodiment of the present invention is the apparatus is designed to accept purpose-specific tea pods, containing loose tea and spices that will drop into the boiler, presenting a benefit for tea brewing over space-constrained flow through coffee pods. In one embodiment of the present invention, a Wi-Fi component is included within the apparatus for communication to external devices and systems such as mobile devices and the internet cloud. In one embodiment of the present invention the milk carafe is treated with a non-stick coating to aid in manual or automatic dishwashing. 
         [0030]    According to one embodiment of the present invention when the invention contains a single boiler to boil both water and milk together, the process flow for brewing tea latte is as follows: 
         [0031]    1. The user first selects a recipe using display. The recipe may be custom made directly before brewing or preloaded and saved to the device. 
         [0032]    2. When the recipe is selected the user will be prompted to fill the milk carafe to a designated level, fill the water tank if empty and insert a tea pod into the pod mechanism. Optionally loose tea and spices may be added in lieu of using a pre-packaged pod containing tea and spices. 
         [0033]    3. After the pod is inserted and the lid is closed, the machine will pump the selected volume of water from the reservoir to the boiler using a pump and flow meter under the control of the programmable microprocessor of the device. The machine will then pump the selected volume of milk from the reservoir to the boiler using a pump and flow meter under the control of the programmable microprocessor of the device. 
         [0034]    4. The water, tea leaves, spices and milk will then he heated together using a tubular heater, until the extraction level reaches the level dictated in the recipe. The extraction level is dictated by brew time and temperature as specified in the selected recipe. 
         [0035]    5. When both the tea and the milk are sufficiently processed, the tea mixture may be briefly mixed with the magnet frothing device and the machine will default to a “keep hot” mode. 
         [0036]    6. The user will be prompted to remove the pod and remove and clean the sieve. 
         [0037]    7. The device will be ready for another cycle when the sieve and carafe are sufficiently cleaned, the pod has been removed and the water reservoir is suitable full. 
         [0038]    According to one embodiment of the present invention when the invention contains separate boilers, one for water and tea, and one for milk, the process flow for brewing tea latte is as follows: 
         [0039]    1. The user first selects a recipe using the display. The recipe may be custom made directly before brewing or preloaded and saved to the device. 
         [0040]    2. When the recipe is selected the user will be prompted to fill the milk carafe to a designated level, fill the water tank if empty and insert a tea pod into the pod mechanism. Optionally loose tea and spices may be added in lieu of using a pre-packaged pod containing tea and spices. 
         [0041]    3. After the pod is inserted and the lid is closed the pod is punctured and the tea falls into the boiler. The machine will pump the selected volume of water from the reservoir to the boiler using a pump and flow meter under the control of the programmable microprocessor of the device. 
         [0042]    4. The water tea leaves and spices will then he heated together using a tubular heater, until the extraction level reaches the level dictated in the recipe. The extraction level is dictated by brew time and temperature as specified in the selected recipe. 
         [0043]    5. In parallel with this process, the milk will be heated and textured by an induction heater and a frothing wheel. 
         [0044]    6. When both the tea and the milk are sufficiently processed, a solenoid valve on the boiler for the tea will open and the tea will combine with the milk. At this stage the tea latte mixture may be briefly mixed and device will default to a “keep hot” mode. The tea-latte is served from the milk container. 
         [0045]    7. The user will be prompted to remove the pod and remove and clean the sieve. 
         [0046]      8 . The device will be ready for another cycle when the sieve and carafe are sufficiently cleaned, the pod has been removed and the water reservoir is suitable full. 
         [0047]    These and other features, aspects and advantages of the present invention will be more fully understood when considered with respect to the following detailed description, appended claims, and accompanying drawings. Of course, the actual scope of the invention is defined by the appended claims.

     DETAILED DESCRIPTION 
     I. Apparatus and Method for Making Tea Latte with an One Embodiment of the Present Invention 
       [0053]    Embodiments of the present invention provide an apparatus and method for making tea latte. 
         [0054]      FIG. 1  is a side view of an apparatus  100  for preparing tea latte. The apparatus  100  includes a body  102  that supports a first container  104  holding water and a second container  106  holding milk. Either container may be removable. In the case of the container holding milk, it is desirable to have a removable configuration so that unused milk can be placed in a refrigerator. The base of each container has a movable disc (e.g., spring loaded) for engagement with a valve, as discussed below. 
         [0055]    The body  102  supports a display  108 . The display  108  accepts preparation parameters for tea latte. For example a slider  110  may be used to specify a tea latte serving size. Other sliders may be used to specify the strength of the tea latte (ranging from a light to dark scale). Another slider may be used to specify fluid mixture percentage (ranging from 100% water to 100% milk). The sliders may be mechanical devices. Alternately, display  108  may be a touch display responsive to physical gestures. The display also includes a start button  112 . The start button  112  may present process information, such as heating, brewing, ready and the like. 
         [0056]    The body  102  defines an aperture  114 . A cup  116  may be placed in the aperture to receive brewed tea latte. 
         [0057]      FIG. 2  is an interior view of the apparatus of  FIG. 1 . The interior view is not to scale. The body includes a first valve  200  to interface with the first container and a second valve  202  to interface with the second container. Fluid from each valve drips into boiler  204 . Alternatively, pumps may be used to transport the fluids. Boiler  204  has an associated heater  206 . The boiler has a third valve  208  to dispense brewed tea latte. A filter may be positioned between the boiler  204  and valve  208  to trap residue. In one embodiment, the filter is removable. 
         [0058]    A microprocessor  210  is connected to a memory  211 . The memory  211  stores instructions to control the brewing process. A mix module  212  includes instructions executed by the microprocessor  210  to process a preparation parameter related to percentage of water and milk. The mix module  212  may also include instructions to process a preparation parameter related to serving size. 
         [0059]    A heat module  214  includes instructions executed by the microprocessor  210  to control the heater  206  and therefore the brewing process. A dispense module  216  includes instructions executed by the microprocessor  210  to control valves  200 ,  202  and  208 . Thus, the dispense module  216  controls fluid intake to the boiler  204  and the dispensation of tea latte to a cup. An actuator  218  may be controlled by the microprocessor  210  to move a tea cartridge  220  into the boiler  204 . 
         [0060]    Preferably, the apparatus is configured for some manual operations. For example, the first container and the second container need not be used. Rather, the boiler  204  may be removed from the body  108 . A milk, water and tea combination may be prepared in the boiler  204  while outside the body  108 . The boiler may then be placed within the body  108 . A user may then specify tea latte strength on the interface  108  and push the start button  112 . 
         [0061]    An embodiment of the present invention relates to a computer storage product with a non-transitory computer readable storage medium having computer code thereon for performing various computer-implemented operations. The media and computer code may be those specially designed and constructed for the purposes of the present invention, or they may be of the kind well known and available to those having skill in the computer software arts. Examples of computer-readable media include, but are not limited to: magnetic media, optical media, magneto-optical media and hardware devices that are specially configured to store and execute program code, such as application-specific integrated circuits (“ASICs”), programmable logic devices (“PLDs”) and ROM and RAM devices. Examples of computer code include machine code, such as produced by a compiler, and files containing higher-level code that are executed by a computer using an interpreter. For example, an embodiment of the invention may be implemented using JAVA®, C++, or other object-oriented programming language and development tools. Another embodiment of the invention may be implemented in hardwired circuitry in place of, or in combination with, machine-executable software instructions. 
         [0062]    Now referring to  FIG. 3  of the present invention.  FIG. 3  is a flow diagram of the brew process for an embodiment of the invention with a single heater and boiler, according to one embodiment of the present invention. The detailed description of the process flow for  FIG. 3  will include references to components previously referred to in the detailed description above of  FIGS. 1 and 2 . In step  310  the user selects a recipe via the display  108 . In step  312  once the recipe is selected, the microprocessor  210  prompts the user via the display  108  to fill the water tank  104  and milk tank  106  to their proper levels. In step  312  the microprocessor  210  also prompts the user via the display  108  to insert a pod and close the lid. 
         [0063]    Still referring to  FIG. 3  of the present invention, in step  314  the microprocessor  210  activates a pump and valve  200  and monitors a flow meter to pump water from the water reservoir  104  into the boiler  204 . In step  316  the microprocessor  210  activates a pump and valve  202  and monitors a flow meter to pump milk from the milk reservoir  106  into the boiler  204 . In step  318  the microprocessor  210  activates the heater  206  to begin the brewing process. In step  318  the microprocessor  210  starts a timer and begins monitoring temperature in accordance with the recipe selected by the user in step  310 . 
         [0064]    Still referring to  FIG. 3  of the present invention, in xf selected in step  310  have been reached. If not the brewing process continues. If the time and temperature parameters related to the selected recipe have been achieved the process proceeds to step  324 . 
         [0065]    In step  324  the microprocessor  210  turns the boiler  206  off and the device enters the “keep hot” mode. Optionally at this point, based on the user-selected recipe, the microprocessor  210  activates the frothing mechanism to mix and froth the combined mixture of tea latte and milk. In step  326  the user is prompted to remove the pod and clean the sieve. 
       II. Apparatus and Method for Making Tea Latte with a Second Embodiment of the Present Invention 
       [0066]    Embodiments of the present invention provide an apparatus and method for making tea latte. In one embodiment of the present invention, the apparatus includes two heaters and two boilers. One boiler for tea and water is fixed; the second boiler for milk also acts as a removable carafe. 
         [0067]    Now referring to  FIG. 4  of the present invention.  FIG. 4  is an overview block diagram of the major components of a tea latte apparatus consisting of two heaters and two boilers, according to one embodiment of the present invention. The block diagram is not to scale. 
         [0068]    Still referring to  FIG. 4  of the present invention, in one embodiment of the present invention, which includes two boilers, one fixed and one removable and two heaters, the apparatus includes a base  400 . 
         [0069]    Still referring to  FIG. 4  of the present invention, mounted on the base  400  the apparatus includes a water reservoir  410 , which the user will be prompted to fill after selecting a recipe if the current water level is insufficient to execute a brew. Connected to the water reservoir  410  is an outgoing water line  450  which is connected to a pump  448  located within the base  400  according to one embodiment of the present invention. Connected to the pump  448  is a water line  452  that supplies water to the tea boiler  432  and is connected to the tea boiler  432  via a valve  418  located near the top of the tea boiler  432  according to one embodiment of the present invention. 
         [0070]    Still referring to  FIG. 4  of the present invention, according to one embodiment of the invention, the apparatus further contains a brew housing  470 , which houses among other components, the pod mechanism  414 , the tea boiler  432 , the heater  420 , the sensor  434 , the valve  422  and other sub-components contained within these above mentioned components. 
         [0071]    Still referring to  FIG. 4  of the present invention, the apparatus further includes a removable sieve  430 , into which a tea and spice mix will be dropped via the puncture of a removable pod  412 . The removable sieve  430  is placed into and located within the tea boiler  432 . 
         [0072]    Still referring to  FIG. 4  of the present invention, the removable sieve  430  is inserted into the device previous to inserting a removable pod  412 . To insert a removable sieve  430  into the device, first the pod lid  458  is raised, then a hollow sieve lid  460  is raised and then the removable sieve  430  is dropped into place in the tea boiler  432 . 
         [0073]    Still referring to Fig. of the present invention, the apparatus further includes a pod mechanism  414 , into which the user will insert a removable pod  412  containing a pre-packaged fresh tea and spice mix. In one embodiment of the present invention, the removable pods  412  are constructed of a flexible plastic body and a foil lid. To insert a removable pod  412 , the pod lid  458  is raised and a removable pod  412  is inserted with the foil side of the removable pod  412  facing downwards. When the pod lid  458  is closed, the puncture mechanism  416 , centered on the bottom of the pod lid  458  presses down on the plastic part of the removable pod  412 , which causes the plastic casing of the removable pod  412  to deform and press against and rupture the foil lid of the removable pod  412 . This deformation and inversion action is much like turning a sock inside out.
