Abstract: Systems and techniques for lobby chat with external anonymous guests are described. The described systems and techniques allow for two-way chat functionality while attendees of a virtual meeting are in a virtual lobby. A virtual lobby is a gateway to a virtual meeting where participants wait for admittance to the virtual meeting. “Lobby chat” refers to a chat within a virtual lobby of a virtual meeting. Advantageously, through the lobby chat, attendees within the virtual lobby can communicate prior to being admitted to the virtual meeting.

Abstract: A chest drainage system including a collection device configured to receive fluid from the pleural cavity of a patient. A sensor is included to detect a pressure differential in the fluid. A display is configured to display a trend in occurrences of changes in pressure of the fluid over time in predetermined time increments based on a number of detections of pressure differentials that exceed a predetermined pressure differential during each of the predetermined time increments. The trend is correlative to the percentage of time that the patient is deemed to have an air leak in the pleural cavity in the predetermined time increments. The trend is derived from a ratio of the quantity of respiratory cycles of the patient for which the predetermined pressure differential is detected (QRCleak) in the predetermined time increments to the total quantity of respiratory cycles of the patient in respective predetermined time increments (QRCtotal).

Abstract: Provided herein are submucosal lifting compositions and methods of using same. The submucosal lifting agents of the disclosure include a polysaccharide, a polyol, and a colorant.

Abstract: A method may include detecting, by a computing device based on a problem signature, that a system has experienced a problem that is associated with the problem signature, wherein the problem signature comprises a specification of a pattern of events indicative of the particular problem experienced by at least one other system; determining that the particular problem violates an operational policy of the system; and deploying one or more corrective measures that modify the system to resolve the problem.

Abstract: In various implementations, an electronic actuator may be coupled to a valve to provide the ability to shut off anhydrous ammonia flow through the valve (e.g., in emergencies). The valve may be coupled to anhydrous ammonia tanks, such as nurse tanks and/or storage tanks. The electronic actuator may include a handle and a bracket. The handle and the bracket may include at least two attractive components that are magnetically attracted to each other upon application of an electric current and the valve may be open. When the electric current is cut, the attractive components of the handle and the bracket may not be magnetically attracted to each other and the valve may be shut off. A controller (e.g., a switch) may be coupled to the electronic actuator to allow control of the electric signal to the electronic actuator.

Abstract: Systems and methods are provided for updating an agricultural prescription for a geographic region. An example computer-implemented method includes executing an agricultural prescription, via farming equipment, in a geographic region and receiving, during execution of the prescription, sensor data from the farming equipment and operating data representing local operating settings for the farming equipment. Task execution data for the agricultural prescription is generated based on the received sensor data and received operating data for the farming equipment, and compared to expected data for execution of the prescription by the farming equipment.

Abstract: A skateboard truck with a swinging arm having an adjustable plane of rotation is described. The truck has a base plate rotatably coupled with a pivoting plate via a pivot assembly. The pivot assembly comprises (i) a bolt about which the swinging arm of the pivoting plate rotates, (ii) an optional centering or biasing member that biases the pivoting plate from an off-center position to a center position, and (iii) a tapered spacer removably disposed between the base plate and pivoting plate. The tapered spacer couples with the pivoting plate in at least two different radial positions to create different angles between the skateboard and swinging arm for different riding styles and user preferences.

Abstract: A method of extracting a target text string includes: at a controller of a data capture device, obtaining an image of an item having the target text string thereon; at the controller, selecting a search area from the image; at the controller, processing the search area via a primary image classifier, to identify a candidate target string; at the controller, validating the candidate target string based on a validation criterion; and displaying the validated candidate target string via an output device of the data capture device.

Abstract: Disclosed herein are systems and methods for the creation, management, and utilization of a multi-region virtual overlay wide area network from a plurality of special purpose network appliances. In exemplary embodiments, multiple regions are created for the virtual overlay wide area network, each region having its own network topology. At least one network appliance from each region is in communication with at least one network appliance from each other region, for inter-region connectivity within the virtual overlay wide area network. A subnet sharing protocol can be utilized to exchange routing information among each network appliance within each region, and between each region.

Abstract: A method includes displaying, via a display device, first content with respect to which a first plurality of editing operations have been performed. The method further includes while displaying the first content, detecting, on the touch-sensitive surface, a first multi-finger gesture. The method further includes in response to detecting the first multi-finger gesture: in accordance with a determination that the first multi-finger gesture includes more than a first predetermined amount of movement in a first direction, undoing one of the first plurality of editing operations; and in accordance with a determination that the first multi-finger gesture includes more than a first predetermined amount of movement in a second direction that is different from the first direction, redoing one of the first plurality of editing operations.

Abstract: The present disclosure generally relates to managing phone calls. In some embodiments, an electronic device with a touch screen displays a phone call user interface which includes informational items associated with phone calls. In some embodiments, when the electronic device receives a request to initiate another phone call, the electronic device displays a contacts user interface including a plurality of contact user interface objects associated with respective contacts.

Abstract: The present disclosure generally relates to managing phone calls. In some embodiments, an electronic device with a touch screen displays a phone call user interface which includes informational items associated with phone calls. In some embodiments, when the electronic device is executing multiple phone calls and receives user input corresponding to an informational item, the electronic device suspends a first phone call and activates a second phone call.

Abstract: A technology is described for a repeater. A repeater can comprise a first port; a second port; a first-direction amplification and filtering path coupled between the first port and the second port; a multiplexer coupled between: the first-direction amplification and filtering path; and the second port; and a power amplifier (PA) coupled between the first port and the multiplexer. The repeater can further comprise an adjustable matching network coupled between the PA and the multiplexer, wherein the adjustable matching network is actively adjusted to match an impedance of an output of the PA at a selected channel over a frequency range for a first-direction signal with an impedance of an input of the multiplexer over the selected channel over the frequency range for a first-direction signal.
