Abstract: A flow splitter may include an inlet, at least two outlets, and an internal vane comprising a first end corresponding to the inlet and a second end corresponding to the at least two outlets, wherein the internal vane is configured to turn, between the first end and the second end, an internal flowing fluid from 0 degrees to a degree between about 60 degrees and 150 degrees. Methods of dividing fluid flow are also provided.

Abstract: There is provided a urine test device for detecting the presence of one or more compounds in urine. The test device comprises a base portion having a detection portion and a flexible attachment portion. The detection portion displays a change when the presence of any one of one or more compounds is detected in urine. The flexible attachment portion is movable from a first configuration to a second configuration in which the flexible attachment portion is extended to enable attachment to a toilet bowl.

Abstract: Implementations include systems and methods for scoring candidates for set recommendation problems. An example method includes repeating, for each code in code arrays for items in a set of items, determining a most common value for the code. In some implementations, the method includes determining that the most common value occurs with a frequency that meets an occurrence threshold and adding the code and the most common value to set-inclusion criteria. In other implementations, the method includes determining a value for the code from a code array for a seed item and adding the code and the most common value to set-inclusion criteria when the value for the code from the code array for the seed item matches the most common value. The method may also include evaluating a similarity with a candidate item based on the set-inclusion criteria and basing a recommendation regarding the candidate item on the similarity.

Abstract: A system for safely disposing of fly/bottom ash from the process of burning coal within a landfill. The system effectively isolates ash from other wastes avoiding reactions, produces little or no leachate, thus reducing treatment costs. It can be operated regardless of weather, is better able to comply with future regulations. Encapsulating fly/bottom ash in bags is far safer, avoids treatment costs and the need for dust control.

Abstract: An asymmetric system for obtaining recommendations is disclosed. A reference magnitude may be obtained from a seed and/or a user model. The reference magnitude may be utilized to adjust the magnitude of candidate vectors that represent one or more items in a multi-dimensional vector space. This permits an item to receive credit for a popularity up to a certain point. The dot products between the adjusted candidate vectors and the seed vector may be obtained and, in some configurations, ranked. The highest dot products may correspond to items that are preferred to be recommended according to an implementation.

Abstract: A user model may be generated using affinity and exposure values for each item a user interacts with in an embedded space. The user model may include exemplars which may refer to representative items in the embedded space. Based on the user model, a recommendation of items may be provided to the user. A truncated form of the user model and/or the recommended items may be sent to the user's mobile device.

Abstract: A cooking appliance includes an oven cavity adapted to be used in cooking foods and a control system includes a display device for presenting available programming options to a user through pictorial images, such as in prompting a user to input information relating to a food product to be cooked. The display device also presents graphical instructions relating to cooking the food product. A controller is provided for establishing a cooking operation within the oven cavity based on the selected programming options.
