Abstract: Among other things, beverages are dispensed from one or more beverage dispensers based on selections made by users. Information about the dispensing of the beverages is sent to a central server where it is used to manage a variety of functions including replacement of depleted supplies of components. Various features of the beverage dispensers enable the beverages that are dispensed to be uniform and appealing to users.

Abstract: Methods, systems, and computer programs are presented for estimating if a user belongs to an audience category. One method includes an operation for accessing events generated at a website. Each event comprises a data structure describing an operation performed by a user, from a group of users, when accessing the website. Further, the method includes an operation for providing event information and information of a first user, for a predefined time window, as input to an audience machine-learning (ML) model. The audience ML model is trained with training data comprising values for features that include event features, user information features, and audience labels. The method further includes operations for generating, by the audience ML model, a score for the first user indicating a probability that the first user belongs to the audience, and for determining if the user belongs to the audience based on the score.

Abstract: Methods, systems, and computer programs are presented for estimating a propensity to buy a product or service. One method includes accessing events generated at a website. Each event comprises a data structure describing an operation performed by a user when accessing the website. Further, the method performs operations, for each user from a group of users associated with an audience, comprising: providing event information for a time window, information of the user, and information for a product as input to a propensity machine-learning (ML) model, the model being trained with training data comprising values for features that include event features, user information features, and audience labels; and generating, by the propensity ML model, a score for the user indicating a probability that the user will purchase the product. Further, the method generates a forecast of purchases of the product for the users in the audience based on the scores.

Abstract: Among other things, a chiller for chilling water to be dispensed as part of beverages includes a tank configured to contain a cooling mass for chilling the water. A first tube in the tank is configured to be immersed in the cooling mass and to carry the water along a path from a source towards a location where the chilled water is to be dispensed as part of the beverages. A second tube is configured to be immersed in the cooling mass and to carry a coolant along a recirculation path from a coolant source and back to the coolant source. The coolant has a sufficiently low temperature to cause a frozen mass to be formed as part of the cooling mass within the tank and in the vicinity of the second tube. The first tube and the second tube are configured and positioned relative to one another within the tank so that the frozen mass occupies at least 30 percent of the volume of the cooling mass in the tank but does not touch the first tube.

Abstract: A grid valve assembly for a steam turbine is provided. The grid valve assembly may include an annular stationary member disposed between an upstream stage and a downstream stage of the steam turbine. The annular stationary member may define a plurality of stationary member openings extending radially therethrough from an outer circumferential surface to an inner circumferential surface thereof. The grid valve assembly may also include an annular rotatable member rotatably disposed about the outer circumferential surface of the annular stationary member. The annular rotatable member may define a plurality of rotatable member openings extending radially therethrough.

Abstract: Disclosed are a hydrogel dressing for covering or treating a wound and a method for preparing the same. The hydrogel dressing includes a matrix structure of a cross-linked mixture, and an elastic sheet coated with an elementary metal or ionic metal embodied in the matrix structure. The mixture comprises a hydrophilic polymer, about 0.5 to about 5 wt % of a photocatalyst agent and at least 80 wt % of water based on the total weight of the mixture.

Abstract: A target apparatus including a portable case; a target; and a drive contained within the portable case, the drive having a drive shaft accessible through an access opening in a side of the portable case. When the target is connected to the drive shaft for rotation relative to the portable case, the portable case provides stable support to the target apparatus.

Abstract: A shooting target apparatus has a portable base capable of staying put on a surface and a target holder for holding a target for shooting. The target holder is supported by the base for pivotal movement. There is a battery-operated drive mechanism in the base for causing movement of the target holder between a concealed position, concealing a target held by the target holder, and a revealed position, revealing the target. Also included is a control circuit controlling the drive mechanism, which includes a wireless signal receiver for receiving a wireless control signal to activate the drive mechanism to cause movement of the target holder from the concealed position to the revealed position and from the revealed position to the concealed position.
