  • Publication number: 20220365072
    Abstract: Methods and devices are provided herein for identifying a cell population comprising an effector cell that exerts an extracellular effect. In one embodiment the method comprises retaining in a microreactor a cell population comprising one or more effector cells, wherein the contents of the microreactor further comprise a readout particle population comprising one or more readout particles, incubating the cell population and the readout particle population within the microreactor, assaying the cell population for the presence of the extracellular effect, wherein the readout particle population or subpopulation thereof provides a direct or indirect readout of the extracellular effect, and determining, based on the results of the assaying step, whether one or more effector cells within the cell population exerts the extracellular effect on the readout particle. If an extracellular effect is measured, the cell population is recovered for further analysis to determine the cell or cells responsible for the effect.

  • Patent number: 11481005
    Abstract: In a display assistant device, a speaker is mounted in a waveguide structure which is at least partially disposed beneath a display screen. The waveguide structure is mounted in an exterior housing which includes speaker grills distributed on a plurality of surfaces of the exterior housing, permitting sound waves from the speaker to be projected outside the exterior housing. A cover structure is disposed on top of the waveguide structure to conceal the waveguide structure and speaker within the exterior housing. The cover structure has a tilted bottom surface configured to be suspended above the waveguide structure and to be separated by a first space. Sound waves projected from an upper portion of the speaker are reflected by the tilted bottom surface and are guided through the first space to exit the device from a speaker grill portion located on a rear side of the exterior housing.

  • Publication number: 20220323091
    Abstract: An articulated instrument and method of its manufacture includes a plurality of segments connected to one another end-to-end, each having a hollow tubular shape defined by a wall, the wall comprising three or more rectangular panels connected along their respective edges at acute angles. A plurality of tendons extends at least partially through the plurality of segments and is configured to apply tension that selectively causes two adjacent segments from the plurality of tendons to bend relative to one another along a pivot joint disposed between the two adjacent segments. The plurality of segments is formed by staggered rectangular portions of a single sheet of stock material, each rectangular portion being folded to form the hollow tubular shape and connected to an adjacent rectangular portion by a tab, each tab defining a respective pivot joint.

  • Publication number: 20220277667
    Abstract: The present disclosure is directed to a system and method for surgical training with low cost, reusable materials and a highly customizable virtual environment for skill-building. According to various embodiments, a surgical training tool is usable in conjunction with a support structure configured to at least partially constrain the tool movement. Meanwhile, the tool is tracked in real-time with off-tool detectors to generate a tool path driving a virtual rendering of the surgical training tool in an operative environment. The virtual rendering may be visually observable via a display device and may include a customizable and/or selectable operative environment with one or more structures that can be operated on by the virtual surgical training tool. By tracking the virtual tool interaction with the virtual structures, a task path may be established for documenting and/or objectively assessing the performance of one or more operative tasks.

  • Patent number: 11316914
    Abstract: A system for intermediated communication between applications running on the same computer is presented. The system routes communication between a first application and a second application through a data broker on a remote server to avoid direct communication between the applications. The first application may be a desktop application, such as a word processing application, that has an add-in installed to facilitate communication through the data broker. The second application may be a web browser that includes a web client implemented using standard functionality of the web browser, without an application-specific plug-in. The data broker operates on a remote server to receive and direct communication between the applications. By eliminating direct communication between the applications, the data broker improves system security and reliability by utilizing communication protocols and capabilities already existing within the computer.

  • Patent number: 11290489
    Abstract: A computing system performs adaptive clustering of machines (e.g., computing devices) and/or machine users in an organization for attack surface reduction (ASR) responsively to event feedback including system-based exclusion events and user-based requests for exclusion. The cluster adaptation may be applied to conventional vector-quantization clustering algorithms, for example K-Means, expectation-maximization (EM) clustering, or affinity clustering, to provide adaptable clusters of machines or users. The adaptation enables aggregation or disaggregation of endpoints into clusters to minimize negative business impacts on the organization while maximizing security in view of changes in the organization that occur dynamically such as varying roles for users, new applications and updates being released, and the like.

  • Publication number: 20220026180
    Abstract: Embodiments include active protection systems and methods for an aerial platform. An onboard system includes one or more radar modules, detects aerial vehicles within a threat range of the aerial platform, and determines if any of the plurality of aerial vehicles are an aerial threat. The onboard system also determines an intercept vector to the aerial threat, communicates the intercept vector to an eject vehicle, and causes the eject vehicle to be ejected from the aerial platform to intercept the aerial threat. The eject vehicle includes a rocket motor to accelerate the eject vehicle along an intercept vector, alignment thrusters to rotate a longitudinal axis of the eject vehicle to substantially align with the intercept vector, and divert thrusters to divert the eject vehicle in a direction substantially perpendicular to the intercept vector. The eject vehicle activates at least one of the alignment thrusters responsive to the intercept vector.
