Abstract: Methods and systems are provided for a transportation vehicle. One method includes configuring a listening threshold value for a Type A, universal serial bus (USB) port on the transportation vehicle; providing an initial power to the USB port without any attached USB device; in response to attaching a USB device to the USB port, detecting an increase in current greater than the listening threshold value; temporarily turning off the initial power to the USB port; setting an operating threshold value, and providing operating power to the USB port; detecting a drop in current when the USB device is disconnected; and resetting the listening threshold value and providing the initial power to the USB port.

Abstract: Embodiments described herein relate to managing wireless connections within a spatially-dense setting like a passenger vehicle, thereby improving quality and reliability of individual wireless connections. An example method includes detecting a connection request from a passenger device requesting a wireless connection with a seatback device in a first in-vehicle location. The method includes defining a density zone that includes other in-vehicle locations surrounding the first in-vehicle location. The density zone localizes an area within which other wireless connections may be disruptive to the wireless connection. The method includes determining, via a token server that stores connection tokens that each describe an existing connection, a number of particular tokens that describe existing connections located within the density zone.

Abstract: A method for generating a ventilation harm index. The method includes accessing data from a plurality of ventilators in operation, analyzing an aggregate of the data, and generating the ventilation harm index based on the analyzed aggregated data.

Abstract: A method for ventilator report generation includes accessing data from a plurality of ventilators in operation, analyzing an aggregate of the data, and generating a ventilator report of a ventilator of the plurality of ventilators based on the analyzed aggregated data.

Abstract: A method for suggesting ventilator protocols includes accessing data from a plurality of ventilators in operation, analyzing an aggregate of the data, and suggesting a protocol for a ventilator of the plurality of ventilators based on the analyzed aggregated data.

Abstract: A method for generating a ventilator avoidance report. The method includes accessing data from a ventilator in operation, comparing the data from the ventilator in operation with associated historical data of another ventilator, and generating a ventilator avoidance report of the ventilator based on the comparison.

Abstract: A method for analyzing medical device data. The method includes accessing data from a plurality of ventilators in operation; analyzing an aggregate of the data; and determining a ventilator operation trend of a ventilator of the plurality of the ventilators based on the analyzed aggregated data.

Abstract: Disclosed is a positive pressure full-face mask comprising a foam cuff, preferably made from a non-reticulated ester polyurethane. The disclosed face mask provides a superior seal to the user's face compared with face masks with air-filled cushion or silicone gasket cuffs, while providing a more comfortable user experience. Also disclosed is a nasal mask with a foam cushion that is more comfortable to the user.
