Abstract: A disc for indicating a position of a ball valve is provided herein. The disc includes a body having an outer circumferential edge and an inner circumferential edge. The inner circumferential edge defines an aperture configured to receive a valve stem. The disc further includes a first indicia and a second indicia circumferentially spaced about the outer edge of the body and circumferentially from one another. When connected to the ball valve, the first indicia is configured to indicate that the ball valve is in an open position and the second indicia is configured to indicate that the ball valve is in a closed position.

Abstract: Disclosed embodiments include apparatuses, systems, and methods for assessing collateral ventilation. An illustrative embodiment includes an occlusion device insertable into a bronchial passageway to selectively seal the bronchial passageway to occlude a lobe of a lung. A flow lumen sealably extends through the occlusion device to a distal end and has a proximal end receptive of a positive pressure flow. A check valve is coupleable with the flow lumen to permit the positive pressure flow to pass to the distal end of the flow lumen and prevent a backflow of pressure from the flow lumen. A flow meter is couplable with the flow lumen to measure the positive pressure flow through the flow lumen. The occlusion device is insertable into the passageway to the isolated lobe. Measurements of the flow meter of the positive pressure flow into the occluded lobe are monitorable to assess collateral ventilation from the occluded lobe.

Abstract: Disclosed embodiments include apparatuses, systems, and methods for assessing collateral ventilation. An illustrative embodiment includes a flow meter input communicatively coupleable with an electronic flow meter positionable to monitor a positive pressure flow into a selectively occluded lobe of a lung. A processing logic circuit is communicatively coupled with the flow meter input to process measurements of the positive pressure flow and to generate a digital representation of the positive pressure flow into the occluded lobe over time. A display device is configured to receive the digital representation and visually present the positive pressure flow over time, a continual decrease over time of the positive pressure flow into the occluded lobe indicating a lack of collateral ventilation from the occluded lobe and a stabilization over time of the positive pressure flow into the occluded lobe indicating a presence of collateral ventilation from the occluded lobe.

Abstract: A system and method are described for providing biometric authentication to mobile nodes, such as mobile nodes seeking a mobile Internet protocol (mobile IP) connection to a network. The mobile node sends a registration request that includes biometric data. If the biometric data is authenticated, the mobile node is provided with a network address, such as an IP address, to use in network communications.
