  • Facilitation of passive intermodulation cancelation via machine learning
    Patent number: 10187098
    Abstract: A passive intermodulation detection system is provided to remotely identify passive intermodulation at a base station site and diagnose the type of intermodulation and location of the non-linearity that is the source of the passive intermodulation. A passive intermodulation cancelation system can generate an equivalent signal to a received interference signal and use the equivalent signal to generate an error signal. The error signal can then be used to reinforce a learning system and converge on a steady state of the interference signal to cancel other interference signals.

  • Integrated humidifier chamber and lid
    Patent number: 10155097
    Abstract: A blower unit for use as part of an integrated blower/humidification system is described. The blower unit has an outer casing, which encloses and forms part of the blower unit, the casing including an air inlet vent. The blower unit further includes a humidifier compartment for receiving a humidifier unit with a separate gases inlet and outlet, the compartment having a heater base for heating the contents of the humidifier unit. The compartment also has a blower inlet port which aligns with the humidifier unit inlet in use, the blower providing a gases path through the casing between the inlet vent and the inlet port. The blower unit also includes a fan for providing a pressurized gases stream along the gases path, and a power supply unit for powering the fan. The gases path is routed over the power supply unit in order to provide a cooling air flow.

  • USABILITY FEATURES FOR RESPIRATORY HUMIDIFICATION SYSTEM
    Publication number: 20180296791
    Abstract: A humidification system for delivering humidified gases to a user can include a heater base, humidification chamber having an inlet, outlet, and associated fluid conduit, and breathing circuit including a supply conduit, inspiratory conduit, and optional expiratory conduit. The humidification system can include various features to help make set-up less difficult and time-consuming. For example, the supply conduit, inspiratory conduit, and optional expiratory conduit can be coupled into a one-piece circuit to aid set-up. Various components can be color-coded and can have corresponding structures to indicate which components should be connected to one another during set-up. Such features can also help make the set-up process more intuitive for an operator, which can reduce the need for specialized training and reduce the number of potential errors.

  • Remote diagnosis and cancellation of passive intermodulation
    Patent number: 10039022
    Abstract: A passive intermodulation detection system is provided to remotely identify passive intermodulation at a base station site and diagnose the type of intermodulation and location of the non-linearity that is the source of the passive intermodulation. The passive intermodulation detection system can generate a test signal in a first band that is transmitted by an antenna. Another antenna can receive a signal in another band, and the passive intermodulation detection system can analysis the received signal to determine whether an intermodulation product due to a non-linearity is present. Based on the type of intermodulation product, period, order, frequency, and etc., the type and location of the non-linearity can be identified.
