Abstract: A method and apparatus are provided for producing a multicomponent feedstock being delivered through a print head of a 3D printer. Multiple component lengths are produced from separate feedstocks and are aligned to form the multicomponent feedstock which is fed into the print head for extrusion. The method includes providing at least two sources of feedstock of different material, feeding a distal end of a first feedstock along a feed path, cutting the first feedstock at a pre-determined length to provide a length of first feedstock having a proximal end. The method includes feeding a distal end of a second feedstock along the feed path and aligning the distal end of the second feedstock with the proximal end of the length of the first feedstock. The second feedstock is cut at a pre-determined length to provide a length of the second feedstock serially aligned with the length of first feedstock, to form a length of multicomponent feedstock. The length of multicomponent feedstock is fed into the print head.

Abstract: The accuracy of directional surveys may be improved using accelerometers, magnetometers, or both. A control system containing accelerometers is configured specifically to correct errors in bias and gain of each accelerometer by requiring the measured field strengths to be as constant as possible over several tool face angles over multiple points in a wellbore, even when all measurements are within a tangent or lateral section of a wellbore. Corrections for the bias and gain errors determined based on one or more measurements from the accelerometers are applied to measurements at other survey points to improve the accuracy of surveys and the efficiency of drilling operations.

Abstract: Devices and techniques are generally described for generating personalized search query suggestions. In some examples, a first search query entered by a user into a search field may be determined. A first keyword associated with the first search query may be determined based at least in part on past interactions of the user with content. In various examples, first string data comprising at least a portion of the first search query and the first keyword may be generated. A data store may be searched using the first string data. A first suggested search string associated with the first string data may be determined. In some examples, the first suggested search string may be displayed on a display in association with the search field.

Abstract: Disclosed are one or more embodiments for a unique and personalized experience for a user interacting with an electronic commerce site by identifying user-preferred item attributes using supervised machine learning and presenting items to the user in an arrangement that is based on the identified item attributes. A shopping mission is determined according to user interactions with an electronic commerce site. The shopping mission is applied to an attribute prediction model that is trained to detect user-preferred item attributes for items included the item category and estimate a likelihood that an item containing a particular attribute will be purchased or interacted with during the interactions with the electronic commerce site.

Abstract: Systems and methods are described for analyzing one or more online shopping missions to determine an estimated stage of a user within the mission and to adjust content for display to the user based on the estimated stage of the user within the mission. The estimated stage of the user within the mission may be determined using a model, such as a machine learning model, that accepts as input signals corresponding to the online shopping mission. The signals may represent user interface interactions and/or other data relating to the user and the mission.
