  • Publication number: 20240233748
    Abstract: In some examples, a non-transitory computer-readable medium stores machine-readable instructions which, when executed by a processor, cause the processor to cause a playback device to produce a sound using an audio file; cause a recording device to record the sound; compare the audio file to the recorded sound; determine, based on the comparison, whether the recorded sound comprises a noise not present in the audio file; and cause, based on the determination, a second recording device to be selected, a multiplexer to select a second playback device, or a combination thereof.

  • Publication number: 20230355452
    Abstract: Device and method for turning a bedridden and immobile patient from left to right and vice-versa. It lessens the risk pressure wounds (bed wound, pressure sore). The device comprises a support surface having a variable geometry to create concave surfaces along the bed. The lowermost zone is formed to the left or to the right of the spine of the patient. Under the effect of gravity, the patient is turned towards the lowermost zone, softly. Once turned, the device also allows the centralisation of the patient towards the middle of the frame. The device may also laterally extend to give more space to a turned patient. By combining the shape change with a timer system, corporal pressure zones of the patient are cyclically displaced. It allows the turning of the patient based on current standards of care.

  • Patent number: 10151475
    Abstract: The present disclosure is directed to a system for determining scaling in a boiler. At least one sensor may monitor a boiler during operation and provide sensor data to a boiler monitoring module including a boiler scaling determination module that may determine an amount of scaling in the boiler. Example sensor data may comprise power input, a temperature of liquid in the boiler and an air temperature within an enclosure housing the boiler. The boiler monitoring module may determine thermal energy transfer to the boiler based on the liquid and enclosure temperatures. A machine learning engine may determine a rate of thermal energy transfer to the liquid in view of the power input, the rate of thermal energy transfer being evaluated by the machine learning engine to identify delay in the rate of thermal energy transfer that quantifies an amount of scaling in the boiler.
