Description

1. Technical area

The present invention relates to an analysis device for determining foam and a method for determining volumes, in particular for foaming drinks or flowable substances, according to the features in the preamble of independent claim 1.

2. State of the art

Beverage containers, such as beer glasses or beer mugs or wine, sparkling wine, cocktail glasses, soft drinking glasses, etc., have defined quantities and are usually provided with calibration marks, on the basis of which the consumer can check whether a sufficient amount of the drink to be paid has been. In practice, especially at events such as marquee farms, beer gardens or the like, but is often not immediately recognizable and verifiable, whether the amount of the beverage is the amount purchased, for example, whether "a measure" beer 1.0 liter or " a half "beer comprises 0.5 liters. The reason for this is in particular that the Einschenkvorgang is carried out very quickly and that filled in the beverage container beverage when serving consists of several phases such as the beer phase and the foam phase. Only after a certain time, the phases combine and it is visible, which is the actual amount of drink to be paid, for example beer, in the drinking vessel. In the case of transparent drinking vessels, the process of connecting the several phases can be followed optically and the quantity of the beverage phase to be paid can be shown. However, the time would have to wait until the phases have joined. This time is not available in practical operation, because on the one hand the operation must serve other guests and not wait as long idle and on the other hand, the consumer freshly tapped his drink, i. immediately after serving, want to consume.

In the case of opaque drinking vessels, for example of stoneware, it is not possible for the consumer to determine from the side the level of the foam phase.

It is of interest in practical operation to be able to estimate which portion of beverage is contained in a foam phase in order to be able to estimate how much volume of the beverage liquid will result after dissolution of the pubic phase.

There are already known devices and / or methods which are concerned in particular with the filling of substances in connection with special drinking vessels.

In the catering industry special drinking vessels, which have appropriate configurations and built-in sensors, too expensive and hygienic difficult to handle, because the measuring shaft in the drinking vessel, possibly mounted on the inside of the drinking vessel sensors and the corresponding electronics not for general cleaning operation in hot water or are suitable in steam. Specially shaped drinking vessels are also expensive and are not accepted in practice for standardization reasons and for reasons of recognition and advertising.

It is also known to carry out foam measurements with devices of the laboratory environment on the basis of defined measuring containers and to measure the time course of the volume decrease in the foam dissolution and to evaluate the measured values. These devices are not mobile and at the time of measurement do not allow the beverage content of a foam phase in any beverage container to be predicted.

It is therefore an object of the present invention to provide a mobile, easily carried, for example, in a handbag, jacket or trouser pocket device and a method, with / a user, such as a consumer, a cook, a host or a bartender who Foam phase of a served in any beverage container beverage cost, reliable and with the highest possible accuracy, quickly, locally, automatically and largely independent of the position of the beverage container and / or determine the device and determine the volume of the currently contained therein content of beverage liquid immediately and can spend.

3. Summary of the invention

The present invention achieves this object by an analysis device according to independent claim 1 and by a method according to independent claim 10. Further preferred embodiments of the present invention are defined in the dependent claims.

Level parameters for the purposes of this invention are actual values of the volumes of the cavities of a beverage container and / or the respective filling level phases. A fill level phase is the phase of a liquid beverage phase or the phase of a gaseous foam phase which partly contains a beverage liquid or a gas phase which is optionally arranged in the beverage container over said phases and which consists essentially of the ambient air. The foam phase or the beverage phase can each go to zero in volume. In the case of a completely filled beverage container, the gas phase in the volume can assume the value zero. The foam phase may protrude beyond the rim and over the cavity of the beverage container.

A foam density s in the sense of this invention is a volume fraction V _{SB of} a beverage liquid per volume fraction V _{S of} a foam phase. The context is as follows: s = V _SB / V _S.

The foam density s (t) is a variable size of the Einschenkparametern to be detected according to the invention, namely the type of beverage liquid, the type of Einschenkvorgangs, the shape and size of the beverage container and from time ti the measurement with respect to the time t0, in which the Einschenkvorgang the filling phase of the beverage liquid and the foam is completed, depends.

The fill level parameters are assigned respective one-dimensional or areal volume characteristics.

These characteristics include, for example, volume characteristics of the beverage container such as, for example, depending on availability and input option of the computer program optionally available or determined by the analyzer values for its nominal volume, container type, size, height, width, radius, shape and / or cross-sectional shape and / or position of the central axis and with respect to a filling phase of the filled beverage or a flowable substance the determined volume characteristic. From this, the corresponding volume value V _{S of} the foam phase and optionally the volume value V _{B of} a beverage phase are determined on the basis of the volume characteristic values of the beverage container.

Parameters of the physical and / or chemical nature, such as the temperature, the CO2 content, the pressure, the alcohol content, the acidity or the pH, the sugar content or the Oechsle value in wine and / or the biological nature , such as the yeast content of the beverage to be filled or alternatively a flowable substance, have an influence on the consistency of the foam phase and are referred to as state parameters in the context of this invention. Condition parameters of the foam phase or individual phases of a beverage liquid or alternatively a flowable substance are optionally provided as default and / or entered by the user and / or current actual values are detected via sensors of the analysis device according to the invention and converted into corresponding foam parameters.

The analysis device according to the invention comprises means for detecting the actual value of the foam volume V _S and optionally the volume V _B of the beverage liquid present in the beverage container and optionally the state parameter of the foam phase and / or of a phase of a beverage liquid already filled into a beverage container or in the filling process.

The analysis apparatus comprises means for detecting the size and shape of the beverage container, means for detecting the type of pouring operation, means for detecting the type of beverage liquid and means for detecting the timing of the analysis with respect to the time of completion of the pouring operation and optionally for detecting the Condition parameters of the beverage liquid and / or the foam phase.

The means for detecting the size and shape of the beverage container are either already stored in the analyzer or in a connected remote computer and either manually by user input or automatically by pattern recognition selecting these Einschenkparameter and the associated Schaumkennwerte.

The means for detecting the type of pouring operation consist in a preset selection and / or manually by user input selecting these Einschenkparameter and the associated Schaumkennwerte. For example, it is detected whether it is a Einschenkvorgang with a dispenser and, where appropriate, which pressure and which CO2 content prevails or whether the Einschenkvorgang from a bottle or by decanting takes place, which temperature has the filled beverage liquid, which type of beverage it is etc. Alternatively, the detection of individual Einschenkparameter via optional sensors of the analyzer and thus acquired state parameters.

These Einschenkparameter determine the foam characteristics, which are used according to the invention for temporal correlation of the foam density. Depending on the combination of the Einschenkparameter different temporal courses of the foam density are used. At time ti the measurement, the actual foam density is determined from the determined foam characteristics about a program stored in the analyzing device or in a connected remote computer computer program s (ti) and using the likewise determined by the analysis device the volume of the foam phase V _S that at this time ti in the foam phase contained volume V _{SB of} the beverage liquid according to the context V _SB = s (ti) * V _S determined and output to the user and / or stored in the analysis device or in a connected remote computer.

According to the invention, the computer program determines the foam characteristics using, for example, an assignment table the foam parameters or, for example, user-entered or optionally preset foam parameters using the slip parameters acquired by the analysis device, for example by user input and / or sensors, and assigns these to the foam density as a function of time from completion the pouring process too. The different courses of this function are stored either as a mathematical function or in the form of one or more assignment tables (lookup tables) assigned to the slip parameters in the analysis device or in a connected remote computer.

Preferably, this relationship is mapped from time t0 through a non-linear function such as the exponential curve of an e-function. Preferably, the relationship is in the form s (t) = S0 · e ^ (- t / tau) displayed. However, other non-linear or linear relationships of the temporal evolution of the foam density from time t0 to the imaging are also possible.

Where s (ti) is the foam density at the time of measurement ti. The time of the measurement is referred to the time t0 at the completion of the Einschenkvorgangs and represents the time elapsed since the time t0 to the time of measurement ti. In practical operation, either the first measurement immediately after the Einschenkvorgang done and the computer program as t0 be used. Alternatively, for the time of pouring to the first measurement, for example, immediately after serving, a defined time period is detected or accepted as a time offset. From this time offset calculates the computer program for the current and possibly following measurements back to the time t0. In the context of the implementation according to the invention, values for a time offset in the range from 0 seconds to 240 seconds, in particular in the range between 60 seconds to 180 seconds, are used.

One of the foam characteristics in this example is S0, the foam density at the time of the pouring process. S0 depends mainly on the type of Einschenkvorgangs and prevailing at the time of Einschenkvorgangs state parameters such as pressure, temperature, CO2 content. These values are different, for example, when the Einschenkvorgang from a bottle or from a dispensing system and they are different depending on the type of beverage liquid. Advantageously, various types of pouring operations and / or beverage liquids can be selected by the user as a Einschenkparameter via means for input such as via a touch-sensitive display unit via the input menu. From this, the computer program determines the associated foam characteristics, which are to be used to determine the current foam density s (ti). In the context of the implementation according to the invention, values for S0 in the range from 0.1 to 0.7, in particular in the range between 0.25 to 0.45, are used.

Tau is one of the foam properties mentioned, which is determined on the basis of the Einschenkparameter, such as size and the shape of the beverage container or the type of beverage liquid from the computer program, for example, from a stored table with associations between recorded Einschenkparametern and Schaumkennwerten. tau is a time constant dependent on the Einschenkparameters, which maps the time course of the foam density s (t) starting from S0. By way of example, the period of time from the moment of insertion can be used as dew, after which the original foam density S0 has decreased by about 66%. In the context of the implementation according to the invention, values are used for tau in the range of 50 seconds to 500 seconds, in particular in the range of 80 seconds to 100 seconds or in the range of 180 seconds to 240 seconds or in the range of 300 seconds to 450 seconds. Alternatively, in the case of other linear or nonlinear functions or table values, for example, it is also possible to use slopes or the derivative of the function for mapping the curve profile and / or to use sections for interpolation between a plurality of interpolation points of the function.

If these Einschenkparameter can be assumed to be constant in repetitive measurements and the same Einschenkparametern, these are optionally preset by the analyzer already preset. Optionally, the user can change the Einschenkparameter manually or the analyzer can change the default setting on detection of deviant values by an automatic selection. This could be the case, for example one of the default deviating size or shape of the beverage container is determined or other than assumed state parameters such as temperature, color, consistency, etc. of the filled beverage liquid can be determined.

The means for specifying Einschenkparametern include optical and / or touch-sensitive and optional acoustic and / or electrical input interfaces for optional specification of a Einschenkparameters and or foam characteristic value. Alternatively, it is optional to specify a slip parameter and / or foam characteristic via a wired or wireless input interface from a local or remote computer, such as an Internet server.

The means for detecting actual values comprise sensors for detecting the characteristic values of fill level parameters and / or optionally the characteristic values of state parameters and for converting the characteristic values into electrical signals that can be processed by the computer of the analysis device. Alternatively, known, assessable or presumable actual values may also be entered by the user and / or a local computer and / or via a remote computer such as an internet server via a wired or wireless input interface and thereby captured and provided for further processing.

Preferably, at least the actual volume characteristic value of the filling phase of the foam and optionally of at least one filling phase of a beverage is detected and in relation to the volumetric parameters of the beverage and / or the volumetric parameters also detected by the analyzer and / or predetermined and / or already stored by the user set flowable substance containing beverage container and determined from this correlation at least one level parameter of the level phase. The means for detecting at least one of the actual values are not permanently connected to the beverage container.

The means for evaluating the analysis device according to the invention can be a computer such as a smartphone, a tablet PC or the like and a computer program for calculating the results to be output, for example the determined volume of the foam phase V _S or the volume contained in the foam phase at the time of the measurement V _{SB of} the beverage liquid or the volume V _{B of} the liquid beverage phase. The calculation takes place on the basis of the parameters detected and / or entered with the mentioned means, wherein the means for evaluation are not permanently connected to the beverage container.

The means for output preferably comprise optical and / or acoustic and / or electrical interfaces for outputting the determined actual values of the fill level and / or state parameters and / or the corresponding characteristic values and the calculation results.

An optical sensor can be positioned on a transparent beverage container and detects according to the invention a one-dimensional linear or alternatively advantageously a two-dimensional planar projection of individual filling level phases and of the beverage container as volume parameters, converts these into electrical signal values which are transferred to a computer program for further processing. In this case, that central axis of the detected projection which is substantially perpendicular, i. has substantially the orientation of the solder axis, interpreted as a central axis of a rotationally symmetrical within a defined height substantially cylindrical cavity about the central axis with a defined radius. In the case of the two-dimensional areal registration, the distance of the central axis from the edge of the detected area is advantageously used as the radius. In one-dimensional detection, the calculation is based on defined parameters of the beverage container, which are passed by the user to a processing program. The processing program determines the assigned volumes of the corresponding cavities of the beverage container and the respective filling level phases from the one-dimensional or areal volume characteristics.

To distinguish individual filling level phases, for example, the effect is exploited that different filling level phases have different optical properties, such as color frequency, reflection or transmittance or refractive index, which can be detected distinguishable from the optical sensor. These differences are used for the differentiation and geometric delineation of the different filling level phases, either by the user marking the limits on the display unit by input or the computer program marking the boundaries automatically, for example by differentiating the transition boundaries from one filling level phase to another. If the computer program marks the transition limits, the user can optionally change these again.

The marked limits, for example, exempt the individual filling level phases. Likewise, when exempting the margins of the beverage container is moved. The Computer program distinguishes the individual volume characteristics and converts the signal values, which represent the volume characteristics optionally after correcting an inclination angle of the beverage container and / or the analyzer and / or a parallax error in the absolute volume values of level parameters of the individual beverage phases and the beverage container. Advantageously, the measurements are repeated at different times and the changes in the volume values of the individual beverage phases are determined. Advantageously, the computer program provides different processing options that are optionally selectable by the user by input.

The result can be output to the user via an output interface of the computer and / or can be stored for later use.

Furthermore, input interfaces are provided, via which the user can input Einschenkparameter for determining the Schaumkennwerte or foam characteristics and individual data such as gender, height, etc. Furthermore, the user can input via the input interface which beverage is involved, such as water, beer [% alc.], Wine [% alc.], Liqueur [% alc.], Spirits [% alc.], Cocktails, Mixed drinks, Radler / Longdrink, etc. or which vessel type or shape has been selected, such as a glass of water, a beer glass, a Maßkrug, a champagne glass, a Weissbierglas, a wine glass or the like. The user may advantageously select a particular one from a molding table or vessel size such as 0.1 liter, 0.2 liter, 0.3 liter, 0.33 liter, 0.4 liter, 0.5 liter, 1.0 Liters, etc. meet.

The analysis device advantageously comprises the means for determining the foam characteristics, wherein the input means are provided for the input of foam characteristics or Einschenkparametern, from which the foam characteristics are determined by a table or a mathematical function.

Advantageously, further sensors which can be immersed in the beverage or attached to the beverage container can be connected to the computer program via a computer interface in order to transfer additional parameters such as the temperature, sugar content, alcohol content of the beverage to the computer program for further processing.

Submersible sensors are particularly advantageous in nontransparent beverage containers, as they may also include optical sensors that detect the filling level phases inside the nontransparent beverage container.

With the analysis device according to the invention and the analysis method according to the invention, the user is able, with the means available locally, for example with the aid of a smartphone, tablet or the like, within a very short time to relatively precisely contain that currently contained in a foam phase at the time of the measurement Volume V _{SB of} a beverage liquid as well as the level parameters and / or the state parameters or respectively the characteristic value of a filled, served beverage or a filled flowable substance to evaluate or adjust based on the results of various optional evaluation programs his drinking behavior. No changes to the beverage container or the beverage or the flowable substance are required. The vessel can be used as usual and its contents can be estimated and consumed.

Optionally, to determine the size of a beverage container, and thus the nominal volume, a reference article of known dimensions such as a matchbox or cigarette box or a standard size bottle or a measuring tape may be provided adjacent to the beverage container to be detected during the two-dimensional optical image acquisition. The reference object serves as a known comparison quantity in order to determine the still unknown size values of the beverage container.

Alternatively, a defined distance u can optionally be used as a measure for calculating the dimensions of the beverage container and thus for determining the volume parameters and nominal volume in the one-dimensional or two-dimensional optical detection of the beverage container. The size values of the beverage container can be determined therefrom, for example, at a defined zoom factor according to the ratios of the jet set or the geometric similarity. Either the user holds in the inventive detection of the beverage container a fixed distance u or from a list selectable distance u between the front edge of the beverage container and camera sensor or he optionally gives the distance u a he estimates or measures. It could, for example, the elbow length of an adult with about 40 cm with outstretched fingers are used as the standard distance u or a user measures his individual measure from once, enters this in the analysis device or stores it there and uses this in the future as a standard distance u. Optionally, the user adjusts the beverage container to be detected in a predetermined frame displayed by the analysis device in the display defined proportions at a defined distance u of, for example, a foot or about 30 cm and optional scaling. The optional scaling advantageously has a parallax correction with respect to the volume characteristic values recorded at a distance u into the absolute volume values of fill level parameters of the individual beverage phases and of the beverage container.

To determine the volume characteristics of the beverage container, the center axis of the detected projection, which is substantially perpendicular, i. has substantially the orientation of the solder axis, interpreted as the central axis of a cylindrical beverage container rotationally symmetrical substantially cylindrical cavity about the central axis with a defined radius. In the case of the two-dimensional areal registration, the distance of the central axis from the edge of the detected area is advantageously used as the radius. In the one-dimensional detection or, advantageously, in the two-dimensional areal detection, the calculation takes place on the basis of defined parameters of the beverage container, which are transferred by the user to a processing program.

In the case of rotationally symmetrical noncylindrical beverage containers, the determination of the volume characteristics of the beverage container is effected by subdividing the cross section of the beverage container, for example in height defined in cross-section disks, in particular at substantially right angles along the central axis. Advantageously, the height of the cross-sectional slices is chosen so small that result in approximately trapezoidal to rectangular cross-sectional slices. The volumes of the individual cross-section disks of a fill level phase are determined individually from the position-dependent volume parameters of the height and the radius, wherein the center axis is interpreted as the axis of rotation of the surrounding cavity and summed or integrated into Vges. The result Vges thus results in the nominal volume of the beverage container, which according to its cross-sectional shape of section or differential volume characteristics as a function of the distribution of the nominal volume in the interior of the beverage container as a function of the position along the central axis of the non-cylindrically shaped rotationally symmetrical beverage container, ie depending on shape, size and beverage container type, composed.
