Abstract: A method for determining a degree of degradation of a user interface worn by an individual during one or more uses of a respiratory therapy system includes receiving data associated with the user interface. The method further includes determining, based at least in part on the received data, a value of at least one degradation indicator associated with the user interface. The method further includes determining the degree of degradation of the user interface based at least in part on the value of the at least one degradation indicator.

Abstract: Methods and systems for forecasting demand for items across multiple channels are disclosed. In some implementations, multi-channel demand forecasting may be performed on a per-item, per-location basis, by selectively generating item-location forecasts for each item and location within a supply chain for each channel, or disaggregating a chain level forecast on a per-item basis to each location. Particular selection of an appropriate model, and selective training of models, allows for efficient computation of such forecasts across a large supply chain with thousands of locations and hundreds of thousands, or millions, of items for which forecasts are generated.

Abstract: Provided are apparatuses and methods for non-invasively and continuously measuring physiological parameters of a mammal subject. The apparatus includes multiple sensor systems attached to the mammal subject, and a microcontroller unit (MCU). The sensor systems are time-synchronized and communicate with each other wirelessly and bidirectionally. Each of the sensor systems includes at least one sensor configured to detect a vital sign of the mammal subject and generate a corresponding one of the physiological parameters. The MCU is in wireless communication with the plurality of sensor systems. In operation, the MCU receives, from the sensor systems, and displays the physiological parameters of the mammal subject. The apparatus and method can be used in applications such as developing therapeutics or vaccines for a disease, or diagnosing a disease.
