  • Publication number: 20240338235
    Abstract: A data parallel pipeline may specify multiple parallel data objects that contain multiple elements and multiple parallel operations that operate on the parallel data objects. Based on the data parallel pipeline, a dataflow graph of deferred parallel data objects and deferred parallel operations corresponding to the data parallel pipeline may be generated and one or more graph transformations may be applied to the dataflow graph to generate a revised dataflow graph that includes one or more of the deferred parallel data objects and deferred, combined parallel data operations. The deferred, combined parallel operations may be executed to produce materialized parallel data objects corresponding to the deferred parallel data objects.

  • Patent number: 12065876
    Abstract: A motorized window treatment may provide a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment may include a covering material (e.g., a cellular shade fabric or a roller shade fabric), a drive assembly for raising and lowering the covering material, and a motor drive unit including a motor configured to drive the drive assembly to raise and lower the covering material. The motorized window treatment may comprise one or more battery packs configured to receive batteries for powering the motor drive unit. The batteries may be located out of view of a user of the motorized window treatment (e.g., in a headrail or in a battery compartment). The motorized window treatment may use various power-saving methods to lengthen the lifetime of the batteries, e.g., to reduce the motor speed to conserve additional battery power and extend the lifetime of the batteries.

  • Publication number: 20170113827
    Abstract: A method, system, and apparatus for transferring a label from a strip of labels to an attachment location includes a presenter jig that includes a label flow path between first and second guides for guiding the strip of labels, a cylinder for advancing the strip of labels, a label alignment lock that centers and locks into place one label from the strip of labels, and an installation jig. The installation jig includes a pickup tool having at least one suction cup for lifting the label from the strip of labels. The pickup tool is rotatable to align the pickup tool with a receiving location. The pickup tool releases the at least one suction cup to drop the label onto the receiving location.
