Abstract: A load shed module configured to be connected in series between a power supply and a load is disclosed. A separate load shed module is connected in series between each load and the power supply. The load shed module determines the frequency of the voltage supplied from the power supply. Based on the frequency, the load shed module determines if utility power is connected or if a generator is connected. If the generator is connected and the frequency of the voltage goes outside of a desired operating range for a preset time, the load shed module disconnects the load from the power supply. Each load shed module includes a priority setting and reconnects its corresponding load after a predetermined time corresponding to the priority setting.

Abstract: Data is migrated. For instance, in response to detection of a failed group in a drive of groups comprising respective blocks, it is determined whether the total number of groups in the drive that have failed is less than a predetermined threshold. Data associated with the failed group is migrated to a reserved group in a reserved space of the drive according to a determination that the total number is less than the predetermined threshold; and a read/write (I/O) request to the failed group is redirected to the reserved group based on a mapping relationship from the failed group to the reserved group. Consequently, data does not need to be repaired on an entire drive due to one failed write request and replacing the drive is avoided, thereby saving resources, time and labor, and improving the impact of the failed write request on the performance of a storage system.

Abstract: A user selects a node that specifies an operation for a dataset. In response, a computer system displays data values for the dataset, in a grid in a data pane. The grid includes a first column and a second column. In the grid, the user edits a first data value in the first column in a first row. The user input changes the first data value to a replacement data value. The computer system identifies a second data value in the second column in the first row, and identifies one or more additional rows in the grid, whose data values for the first column and the second column match the first data value and the second data value. The computer system then updates the data value in the first column for a second row in the grid to the replacement data value.

Abstract: A method prepares data for subsequent analysis. The method displays a user interface that includes a plurality of panes, including a data flow pane and a data pane. The data flow pane includes a flow diagram having a plurality of nodes, each node specifying a respective primary operation or specifying a plurality of secondary operations to clean a respective data set. The data pane includes a plurality of data values in rows and columns. The data values correspond to a selected node in the data flow pane. A first user input selects a first data value in a first column and receives a second user input to edit a second data value in a second column according to one or more predefined conditions. The method then highlights the second column. When the predefined conditions are met, the method changes the second data value to a replacement data value.

Abstract: Systems and methods for controlling isochronous data streams are disclosed. Particular aspects of the present disclosure are designed to be used with almost any isochronous data stream, but are well-suited for use with the Universal Serial Bus (USB) protocol. Further, aspects of the present disclosure are flexible to accommodate existing configuration possibilities within the USB protocol as well as accommodate proposed future changes in the USB protocol. The flexibility of the systems and methods is provided by calculating: (1) drift between a USB host system time and the application and (2) drift between the USB host system and a USB device clock. Based on these two drift calculations, a time stamp may be synthesized to program a next delivery schedule. Using this time stamp, jitter correction can take place and uniformly-sized packets may be assembled to pass to an application processor.

Abstract: A lock comprising a shackle and a shackle-receiving portion. The shackle can comprise a resilient flexible portion, which, absent any external deformation forces, can retain an overall substantially U-shaped form. The shackle-receiving portion can comprise a locking mechanism operable to secure the shackle to the shackle-receiving portion. The substantially U-shaped form can comprise substantially straight and parallel legs. The flexible portion can further comprise a heat-treated coil spring that maintains the overall substantially U-shaped form, and the shackle can further comprise a cable.

Abstract: Methods, systems, and devices are described for media synchronization. Multi-stream media processes may include media streams captured with respect to different clock rates. Multi-processor implementations may involve separate clocks associated with different media streams, such as audio and video, respectively. The separate clocks may tend to drift from one another, becoming further out of sync as time passes. Selecting a reference time of one of the processors to function as a “wall clock,” recording frame capture times with respect to the reference time, accounting for propagation delays, and transmitting frame capture times in terms of the reference time may aid in AV synchronization at a device where audio and video streams are received.
