  • Patent number: 11550003
    Abstract: A sensing system, and method of operating same, can act as a highly sensitive gradiometer. A first non-magnetic element, such as a sphere, is driven at a first resonance frequency along an axis. A magnet is attached to a second non-magnetic element, such as a plate, and driven at a second resonance frequency along the axis. The first non-magnetic element and the second non-magnetic element are coupled by a force along the axis, in resonance. The gradiometer is configured to determine a gradient magnetic field acting on one or more of the first non-magnetic element and magnet based on change in at least one resonance characteristic.

  • Patent number: 11552247
    Abstract: An organic vapor deposition device comprises a print head, comprising a source channel, in fluid communication with a flow of carrier gas and a quantity of organic source material configured to mix with the carrier gas, a nozzle having a deposition outlet, in fluid communication with the source channel, and a shutter configured at least to open and close the deposition outlet, wherein the print heat is configured to allow the flow of carrier gas and the organic source material exit the deposition outlet when the shutter is in an open position, and to prevent the flow of carrier gas and the organic source material from exiting the deposition outlet when the shutter is in a closed position. A method of manufacturing a device comprising an organic feature on a substrate is also described.

  • Patent number: 11464559
    Abstract: Various aspects of a generator, ultrasonic device, and method for estimating a state of an end effector of an ultrasonic device are disclosed. The ultrasonic device includes an electromechanical ultrasonic system defined by a predetermined resonant frequency, including an ultrasonic transducer coupled to an ultrasonic blade. A control circuit measures a complex impedance of an ultrasonic transducer, wherein the complex impedance is defined as Z g ? ( t ) = V g ? ( t ) I g ? ( t ) . The control circuit receives a complex impedance measurement data point and compares the complex impedance measurement data point to a data point in a reference complex impedance characteristic pattern. The control circuit then classifies the complex impedance measurement data point based on a result of the comparison analysis and assigns a state or condition of the end effector based on the result of the comparison analysis.

  • Publication number: 20220230825
    Abstract: A method for performing a low energy pulse testing in a power distribution network that causes contacts to close and then open in about one fundamental frequency cycle of current flow time and close on a voltage waveform that produces symmetrical fault current. The method includes energizing a magnetic actuator to move the actuator against the bias of a spring to move a movable contact towards a fixed contact. The method also includes de-energizing the actuator when the movable contact makes contact with the fixed contact so as to allow the spring to move the movable contact away from the fixed contact so that the amount of time that the current conducts is about one fundamental frequency cycle of the current, where energizing the magnetic actuator occurs when an applied voltage on the switch assembly is at a peak of the voltage wave so that the current is symmetric.

  • Patent number: 11292245
    Abstract: A device includes a nozzle including a discharge end for discharging a fluid, a shutter plate including an aperture, the shutter plate positioned at the discharge end of the nozzle, a plurality of tethers coupled to the shutter plate, and a plurality of electrostatic actuators. Each of the plurality of electrostatic actuators are coupled to one or more of the plurality of tethers. The plurality of electrostatic actuators are configured to move the shutter plate between an open position and a closed position relative the discharge end of the nozzle. In the open position, the aperture is in fluid communication with the discharge end of the nozzle to permit fluid from the discharge end of the nozzle to flow through the aperture. In the closed position, at least a portion of the shutter plate inhibits fluid from the discharge end of the nozzle from flowing through the aperture.

  • Patent number: 11084215
    Abstract: A method for fabricating an electrode includes forming a 3D shell having a hollow interior and defining one or more openings, and directing an electrically conductive liquid through at least one of the one or more openings of the 3D shell, such that the 3D shell is at least partially filed with the electrically conductive liquid. The electrically conductive liquid can be caused to solidify within the 3D shell to form a solid electrode, or can remain a liquid to form a liquid electrode. The 3D shell can be formed having the one or more openings using a 3D printing process such as a two-photon writing system. The surface tension of the electrically conductive liquid aids in retaining the electrically conductive liquid within the 3D shell. The electrode can contact a tissue sample through one of the openings in the 3D shell.

  • Patent number: 10841331
    Abstract: A method for managing quarantines. A quarantine triggered by a network access policy is detected by a computer system. A determination is made by the computer system of whether to enforce a quarantine rule for the quarantine utilizing a quarantine enforcement model trained utilizing a machine-learning process to classify quarantine rules in response to detecting the quarantine rule. The quarantine is deactivated by the computer system when the quarantine rule is classified as inappropriate such that a risk of a threat is balanced with a group of operational considerations.

  • Patent number: 8739694
    Abstract: A control system for a controlled atmosphere room (“CA room”) for storing perishable commodities, such as fruits and vegetables. The control system includes an enclosure that can be placed within the CA room to store a representative sample of the commodities in the CA room. The control system includes an atmosphere valve selectively operable to provide atmospheric communication between the enclosure and the CA room or to isolate the enclosure from the CA room. The control system includes a sampling control system for determining a dynamic control value based on the isolated representative sample. The dynamic control value may be determined by monitoring the respiratory quotient in the enclosure while it is isolated. Once determined, the control system can use the dynamic control value to adjust the atmosphere of the CA room, thereby using tests on a representative sample to control the atmosphere for the full volume of commodities in the CA room.
