A client device generates a plurality of application windows. For example, a first application window may be provided by a first application that has a first session established with a server system, and a second application window may be provided by a second application that has a second session established with the server system. The client device detects user activity in the first window. Based on the user activity in the first window, the client device sends a message to the server system. The message providing an indication of user activity in one or more of the plurality of windows. The message causes the server system to maintain the second session as active despite inactivity in the second application window.

A communication system is provided. The communication system includes slave modules outputting collected data to a master module, and outputting data priority processing request information to the master module; and the master module connected to slave modules, collecting data from the slave modules, and processing, by priority, data from a corresponding slave module based on the data priority processing request information received from at least one slave module.

Superconducting devices with enforced directionality and related methods are provided. In one example, a device including a first Josephson junction transmission line (JTL) for propagating a first set of quantum signals in a first direction and a second JTL for propagating a second set of quantum signals in the first direction is provided. The device may include a logic gate having a first input terminal for receiving the first set of quantum signals via the first JTL, and a second input terminal. The device may include a unidirectional buffer having a first input terminal for receiving the second set of quantum signals via the second JTL and an output terminal for coupling the second set of quantum signals to the second input terminal of the logic gate, where the unidirectional buffer may be configured to propagate quantum signals in only the first direction.

A computer-implemented method includes writing, by a producer, data to one or more buffers. The one or more buffers include a plurality of cells and together form a circular buffer, and an input cursor indicates which cell of the plurality of cells the producer writes to. The method further includes reading, by a consumer, data from the one or more buffers, where an output cursor indicates which cell of the plurality of cells the consumer reads from. It is detected that the consumer is overrun by the producer. A throughput of the consumer is compared to a throughput of the producer, responsive to detecting that the consumer is overrun by the producer. The output cursor is synchronized to a new position, by a computer processor, where the new position is selected based on comparing the throughput of the consumer to the throughput of the producer.

Techniques for enabling filter-level access to a virtual disk (VMDK) are provided. In one set of embodiments, an application can invoke a first application programming interface (API) for opening the VMDK, the invoking of the first API causing an ordered group of filters associated with the VMDK to be instantiated. The application can further coordinate with a target filter in the ordered group of filters to establish a communication channel with the target filter and can receive, from the target filter, a handle to the target filter via the communication channel. The application can then issue an I/O request to the VMDK via the target filter using the handle, the issuing causing data associated with the I/O request to be filtered by other filters that are downstream from the target filter in the ordered group.

Memory efficient methods determine corrected color values from image data acquired by a nucleic acid sequencer during a base calling cycle. Such methods may: (a) obtain an image of a substrate (e.g., a portion of a flow cell) including a plurality of sites where nucleic acid bases are read; (b) measure color values of the plurality of sites from the image of the substrate; (c) store the color values in a processor buffer of the sequencer's one or more processors; (d) retrieve partially phase-corrected color values of the plurality of sites, where the partially phase-corrected color values were stored in the sequencer's memory during an immediately preceding base calling cycle; (e) determine a prephasing correction; and (f) determine the corrected color values. In various implementations, these operations are all performed during a single base calling cycle. In certain embodiments, the methods additionally include using the corrected color values to make base calls for the plurality of sites. Sequencers may be designed or configured to implement such methods.

A display device includes an organic light emitting display panel and a control module. The organic light emitting display panel includes a first display part and a second display part bent from the first display part with respect to a bending axis and configured to display a gradation image. The control module is configured to control images displayed in the first and second display parts. At least one of color, brightness, and chroma of the gradation image is varied along a direction crossing the bending axis of the organic light emitting display panel. A user perceives that an image distortion caused by a shape of the organic light emitting display panel is caused by the gradation image.

Various structures and methods are disclosed related to configurable scrambling circuitry. Embodiments can be configured to support one of a plurality of protocols. Some embodiments relate to a configurable multilane scrambler that can be adapted either to combine scrambling circuits across a plurality of lanes or to provide independent lane-based scramblers. Some embodiments are configurable to select a scrambler type. Some embodiments are configurable to adapt to one of a plurality of protocol-specific scrambling polynomials. Some embodiments relate to selecting between least significant bit (LSB) and most significant bit (MSB) ordering of data. In some embodiments, scrambler circuits in each lane are adapted to handle data that is more than one bit wide.

According to embodiments of the invention, methods, computer system, and apparatus for virtual channel management and bus multiplexing are disclosed. The method may include establishing a virtual channel from a first device to a second device via a bus, the bus having a first bus capacity and a second bus capacity, the second bus capacity having greater capacity than the first bus capacity, determining whether a store command is issued for the first bus capacity, determining whether the first bus capacity is available, and allocating the second bus capacity and marking the second bus capacity as unavailable in response to the store command if the first bus capacity is unavailable.
