Abstract: A method of printing a multi-material part in a layer-wise manner with an extrusion-based 3D printer includes providing a sliced digital model of a multi-material part and determining a number of materials in each of the slices of the digital mode. The method includes utilizing a digital model of a purge tower having N subdivisions having a closed geometry, wherein N is the number of print heads needed to print the part that is greater than or equal to three, each adjacent subdivision contact one another along an interface and assigning each print head to one subdivision and to tool paths forming the one subdivision in each layer. The method includes reassigning the assigned subdivision within the purge tower of an inactive print head in a layer to a print head that is active in the layer of the multi-material part.

Abstract: A system includes a processor configured to perform operations, including receiving, from a client device, a request, associated with a user identifier, for rendering of a graphical user interface (GUI), and obtaining, based on the request and from persistent storage, a framework definition that specifies a first plurality of components and a layout thereof within the GUI. The operations also include determining a second plurality of components by way of a machine learning model and based on attributes associated with the user identifier, and determining, for each respective component of the second plurality of components, a corresponding visual format and a corresponding position within the GUI. The operations further include updating the framework definition by combining the first plurality of components and the second plurality of components based on the corresponding visual format and the corresponding position, and transmitting the framework definition as updated to the client device.

Abstract: A system includes a processor configured to perform operations, including receiving a request for a graphical user interface (GUI). The operations also include, in response to the request, generating a representation of the GUI to include navigational components and a fixed panel component, where the navigational components are positioned at predetermined locations within the GUI. A particular navigational component is configured to, in response to selection thereof, cause display of a corresponding plurality of child components arranged according to a corresponding predetermined hierarchy. The fixed panel component is positioned at a further predetermined location within the GUI and configured to, in response to a repositioning of the particular navigational component from its corresponding predetermined location to the fixed panel component, display the corresponding plurality of child components as a hierarchical list based on the corresponding predetermined hierarchy.

Abstract: A portable sink includes a container for holding wash water, an inlet line to bring fresh water into the container, and an outlet line to remove wastewater from the container. A float valve on the inlet line maintains wash water at a selected level within the container. A faucet attached to the float valve may further provide a separate source of clean water to the user. The outlet line further includes a siphon to draw the wastewater from the container to a selected discharge location. The inlet and outlet lines may form an assembly with an inverted U shape so that the device may straddle the wall of a bucket so that no piping penetrations are made through the wall. The siphon preferably includes an airlock to prevent the ingress of air at the discharge end under conditions of less than maximum flow.

Abstract: A method for extinguishing a candle at timed intervals using a combustible material is disclosed. In one exemplary embodiment, the method includes: utilizing a combustible composition adapted for application to a wick segment; utilizing a combustible first wick segment; coupling a combustible second wick segment to the combustible first wick segment; placing the combustible second wick segment adjacent to the first wick segment; and configuring the combustible second wick segment to, as the combustible first wick segment, once ignited, burns down to the combustible second wick segment, interrupt and slowly self-extinguish the burning of the first wick segment. The candle wick is configured to be relit, post extinguishment, without having to physically remove a non-combustible barrier. A combustible composition also is disclosed. A candle further is disclosed.

Abstract: A method, apparatus, computer implemented method and computer programmed product for recovering data from a split sector associated with an inoperable servo timing mark. Instead of using a servo timing mark to synchronize the read/write head to the spin speed variation of a storage media, the trailing end of the data fragment preceding the inoperable servo timing mark is used as a reference point. After detecting the reference point, the read operation is halted a predetermined delay time after which the read operation is resumed recovering the data from the sector relying on the inoperable servo timing mark.

Abstract: a firm ware based technique related to managing defective data sector information in a disk drive. Specially, technique provides for a dynamic method by which the number of spare or served alternate sectors and their locations can be allocated in the event defective data sectors exist. One advantage of the present invention exists for certain applications where the capacity and/or configuration of the drive are configured at run time. The present invention also has the advantage of improving performance when accessing “grown” defects by allowing the block relocation information to be placed physically closer to the location of the defective blocks.

Abstract: The invention comprises a magnetic disk storage system and comprises method for configuring the magnetic disk storage system. The magnetic disk storage system facilitates write and read operations that compensate for variances that are experienced with magnetic disk storage systems. When writing data to a data sector, the magnetic disk storage system utilizes a phase lock oscillator field that has a length that is specified for that data sector. When reading from a data sector, the magnetic disk storage system utilizes an incremental read delay that has a duration that is specified for that data sector. Data sectors with shorter data sector delay periods can have shorter phase lock oscillator fields than data sectors with larger data sector delay periods. This frees-up memory space and increases the capacity and performance of the magnetic disk storage system.
