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.

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.

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.

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.

Abstract: The present invention provides an oxidation sensor for an electrical circuit or MEMS device that includes a conductor located on an insulating substrate and a sensor trace located on the insulating substrate adjacent the conductor. The sensor trace is located on the insulating substrate adjacent the conductor and is configured to oxidize at a rate greater than an electrical component associated with the sensor trace on the electrical circuit or MEMS device when the sensor trace and the electrical component are exposed to a same oxidizing environment. By oxidizing and thus becoming an open circuit more rapidly than any structure on a electrical circuit or MEMS device at a given relative humidity (i.e. in the same package), the oxidation sensor is designed to provide early warning of oxidation. Thus, the present invention serves as a sensor that will give advance warning of a leaky package and associated oxidation.
