  • Patent number: 11433202
    Abstract: In certain embodiments, a ventilator may provide interactive guidance for obtaining a subject's expiratory flow limitation results. In some embodiments, the ventilator may cause a progressive color component to be presented, where the progressive color component indicates a progression from one color proximate one side of the progressive color component to another color proximate another side of the progressive color component. The ventilator may cause a forced oscillation to be continuously applied to an airway of the subject for a time period. The ventilator may monitor the subject's degree of expiratory flow limitation based on output signals generated by one or more sensors as the forced oscillation is continuously applied for the time period. The ventilator may cause, based on the monitoring, a movable component's position on the progressive color component to be continuously updated during the time period to indicate the degree of expiratory flow limitation.

  • Patent number: 11295021
    Abstract: Approaches for monitoring a host operating system. A threat model is stored and maintained in an isolated execution environment. The threat model identifies for any process executing on a host operating system how trustworthy the process should be deemed based on a pattern of observed behavior. The execution of the process and those processes in a monitoring circle relationship thereto are monitored. The monitoring circle relationship includes a parent process, any process in communication with a member of monitoring circle relationship, and any process instantiated by a present member of monitoring circle relationship. Observed process behavior is correlated with the threat model. Upon determining that a particular process has behaved in a manner inconsistent with a pattern of allowable behavior identified by the threat model for that process, a responsive action is taken.

  • Patent number: 10792457
    Abstract: A humidifier for an airway pressure support system, includes a base, a number of side walls extending from the base, and a top wall provided opposite the base, wherein the base, the number of side walls, and the top wall are made from an elastomeric material and at least partially define an internal chamber for receiving and holding a liquid. The humidifier also includes a plurality of support structures provided on or within the humidifier, each support structure extending along at least the number of side walls, wherein the humidifier is structured to collapse from an initial, expanded condition to a collapsed condition when a compressive force is applied to the top wall in the initial, expanded condition and to automatically return to the initial, expanded condition when the force is removed.

  • Patent number: 10534384
    Abstract: A current mode switching regulator circuit and operating method includes a variable duty cycle power switch controller, a voltage feedback loop that provides a feedback signal based on the output voltage, a current feedback loop that provides a current sense signal based on the output current, and an offset circuit having an external signal input and coupled to the current feedback loop. The power switch controller controls the switching regulator circuit to generate an output voltage and an output current. The offset circuit is configured to provide an offset output control signal, independently of the voltage feedback loop, to control the power switch controller so as to vary a duty cycle of the power switch controller based on the current sense signal and an external offset signal applied to the external signal input.

  • Patent number: 9514507
    Abstract: The present disclosure is directed towards methods and systems for maintaining state in a virtual machine when disconnected from graphics hardware. The virtual machine is one of a plurality of virtual machines hosted by a hypervisor executing on a computing device. A control virtual machine may be hosted by a hypervisor executing on a computing device. The control virtual machine may store state information of a graphics processing unit (GPU) of the computing device. The GPU may render an image from a first virtual machine. The control virtual machine may remove, from the first virtual machine, access to the GPU. The control virtual machine may redirect the first virtual machine to a GPU emulation program. The GPU emulation program may render the image from the first virtual machine using at least a portion of the stored state information.

  • Patent number: 9110700
    Abstract: The methods and systems described herein provide for preventing a non-trusted virtual machine from reading the graphical output of a trusted virtual machine. A graphics manager receives a request from a trusted virtual machine to render graphical data using a graphics processing unit. The graphics manager assigns, to the trusted virtual machine, a secure section of a memory of the graphics processing unit. The graphics manager renders graphics from the trusted virtual machine graphical data to the secure section of the graphics processing unit memory. The graphics manager receives a request from a non-trusted virtual machine to read graphics rendered from the trusted virtual machine graphical data and stored in the secure section of the graphics processing unit memory, and prevents the non-trusted virtual machine from reading the trusted virtual machine rendered graphics stored in the secure section of the graphics processing unit memory.

  • Patent number: 8924571
    Abstract: The methods and systems described herein are directed to providing, to virtual machines, access to data associated with a connection to a wireless local area network, in a computing device executing a hypervisor hosting a first virtual machine and a second virtual machine. A first driver executed by a first virtual machine of the first physical computing device establishes a network connection to a second physical computing device, via a wireless local area network interface of the first physical computing device. The first driver receives from a second driver executed by a second virtual machine of the first physical computing device, a request for a characteristic of the network connection. The first driver provides, responsive to the request, data comprising the requested characteristic to the second driver.
