Abstract: A system and method for providing compliance predictions for using a respiratory pressure therapy device in a treatment regimen is disclosed. The system includes a respiratory pressure therapy device having a transmitter and an air control device to provide respiratory therapy to a patient. The respiratory pressure therapy device collects operational data and transmits the collected operational data. Demographic data of the patient is collected. A predicted compliance with the treatment regimen is determined based on inputting operational data and demographic data to a machine learning compliance prediction model having a compliance prediction output. The machine learning model is trained from the operational data and demographic data of a population of patients using respiratory pressure therapy devices.

Abstract: An electronic scale performs a post-weighing calibration in which the user steps on the scale, and the scale provides an estimated weight based on the scale's stored tare weight determined after the previous weighing performed by the scale. The person steps off of the scale while the estimated weight is displayed, and the scale automatically performs the calibration process to determine the scale's tare weight and verifies the weight. The estimated weight is shown with an orange ellipsis, and the verified weight is shown with a green checkmark. The scale compares the stored tare weight with the new tare weight, and if the difference between the stored tare weight and the new tare weight is within a variation threshold, the scale identifies the weight as being verified. If the difference exceeds the variation threshold, the scale recalculates the weight, displays the corrected weight, and produces a tone as an alert.

Abstract: Systems and methods for waking a controller from a sleep mode are described. In one example, the controller may be woke in response to an estimated amount of time that it will take for a temperature in an evaporative emissions system to be within a threshold temperature of ambient temperature.

Abstract: Methods and systems are provided for assessing a state of a vent hose that fluidically couples a crankcase of an engine to an engine air intake system. In one example, a method may include sealing the crankcase from the vent hose, initiating cranking of the engine, monitoring a series of pressure pulsations during a monitoring window duration via a pressure sensor positioned between a crankcase oil separator and the vent hose, and indicating a presence of degradation associated with the vent hose based on the series of pressure pulsations and the monitoring window duration. In this way, diagnosis of a state of the vent hose may be reliably assessed without crankcase pressures confounding pressure measurements as recorded via the pressure sensor.

Abstract: Methods and systems are provided for monitoring a crankcase ventilation system. In one example, a method may include diagnosing a breach in a crankcase vent tube based on a regression of measurements of pressure in the crankcase vent tube. The regression allows the pressure measurements to be extended across an entire range of operating air flows and the breach may be identified by comparing the regressed pressure measurements to expected crankcase vent tube pressures.

Abstract: Systems and methods are provided that provide respiration entrainment cues to a user to encourage relaxation or a sleep state. The entrainment cues may be audible, visible, or tactile (or any combination). The entrainment cues include a rhythmic component associated with a target respiration rate and may include sub-components associated with a target breath architecture, such as an inhale-exhale cycle. The systems and methods detect the user's respiration to determine whether the user's respiration matches the entrainment cues or whether the user has fallen asleep.

Abstract: Methods and systems are provided for diagnosing a positive crankcase ventilation (PCV) system. In one example, a diagnostic method for a PCV system is provided that includes, when an intake manifold air pressure is above a threshold boost value, determining a PCV system breach based on a pressure determined using a pressure sensor positioned on a clean side of an oil separator coupled to a crankcase and receiving crankcase gas from the crankcase. In the PCV system a ventilation line provides fluidic communication between the oil separator and an intake conduit upstream of a compressor.

Abstract: Provided are methods and systems for measuring and controlling nozzle areas of variable area fan nozzles. A control system attached to a nozzle may include a cable having one end connected to a linear displacement measuring device, such as a string potentiometer. The other end of the cable may be connected to a petal. A reference portion of the cable extends across multiple petals of the nozzle and, in some embodiments, substantially parallel to the nozzle circumference. The linear displacement measuring device measures any changes in the length of this reference portion as the petals actuate outwardly or inwardly during operation of the nozzle. The output of the linear displacement measuring device may be used to control actuators that move the petals. In some embodiments, potentiometer's output may be combined with one or more outputs from other sensors, such as a linear variable differential transducer and/or thermocouple.

Abstract: Environmental risk levels are leveraged to provide dynamic, user-tailorable, actions to detect network compliance and/or to remediate via manual and/or automatic means to bring the network into compliance given the risk level. The risk levels can be based on a combination of business, security, and operation factors and the like. Potentially different remediation steps can be performed on a network-wide basis and/or on individual items of the network based on a current level of environmental risk. Instances can include a management console that can provide a centralized point of administration that allows an organization to review a state of compliance with a security policy across a network environment and/or select a current level of risk which can drive a configuration management engine appropriately. The configuration management engine can utilize existing components to facilitate in detection and/or remediation of the computer network.
