Abstract: A medical device hub power management system, method, and apparatus are disclosed. An example hub connectivity station includes a connectivity stage configured to provide a data connection with an external network. The hub connectivity station also includes at least one docking apparatus configured to connect to at least one medical device. The docking apparatuses are connected to the connectivity station in a stacked arrangement. The docking apparatuses and connectivity stage include power and data connectors to enable data and power to be provided through the hub connectivity station. To prevent electrical shock, a top power connector of each docking apparatus is disconnected from power when that docking apparatus is not connected to another docking apparatus or the connectivity stage. Power is provided to the top power connector after detecting another docking apparatus or the connectivity stage is connected to the top of the docking apparatus.

Abstract: A data classification system obtains a data set including first data associated with a first characteristic and second data associated with a second characteristic. In response to obtaining the data set, the system uses a classification model to generate a classification by classifying the first data into majority data and the second data into minority data. From the classification and using the classification model, the system determines a loss. The system modifies the classification model based on this loss to generate an updated classification model. The system uses the updated classification model to re-classify a subset of the first data into the minority data and a subset of the second data into the majority data.

Abstract: A respiratory treatment device comprising at least one chamber, a chamber inlet configured to receive air into the at least one chamber, at least one chamber outlet configured to permit air to exit the at least one chamber, and a flow path defined between the chamber inlet and the at least one chamber outlet. A restrictor member positioned in the flow path is moveable between a closed position, where a flow of air along the flow path is restricted, and an open position, where the flow of air along the flow path is less restricted. A vane in fluid communication with the flow path is operatively connected to the restrictor member and is configured to reciprocate between a first position and a second position in response to the flow of air along the flow path.

Abstract: A self-service kiosk includes a housing and an imaging device in a key fob receptacle in the housing. The imaging device captures an image of a master key fob placed in the receptacle. The kiosk includes a key fob dispenser having a dispensing slot to receive a duplicated key fob and a dispensing mechanism to dispense the duplicated key fob into the dispensing slot. The kiosk also includes a processor that receives an image from the imaging device, and detects a presence of the master key fob in the key fob receptacle based on an analysis of the received image. Upon detecting the presence of the master key fob, the processor reads codes stored on the master key fob, writes the codes on a blank key fob to generate the duplicated key fob, and causes the dispensing mechanism to dispense the duplicated key fob in the dispensing slot.

Abstract: Technologies are disclosed for providing name resolution services to components executing in a virtualized environment. A name resolution request generated by a component executing within a virtualized environment is intercepted and forwarded from the virtualized environment to a host operating system (“OS”). A user process is then executed that requests that the host OS resolve a name specified by the intercepted name resolution request. Once the user process has received a response to the name resolution request made to the host OS, a response to the original name resolution request made by the component executing within the virtualized environment can be generated based on the response received by the user process. The response to the original name resolution request can then be provided to the component executing in the virtualized environment that requested name resolution.

Abstract: Technologies are disclosed for enabling virtual private network (VPN) support in a virtualized environment. The presence or creation of a host VPN adapter on a host processing system providing a virtualized environment is detected and, in response thereto, a virtual network adapter is created in the virtualized environment. A guest operating system (OS) creates a guest VPN adapter in the virtualized environment. A software component is inserted between the guest VPN adapter and the virtual network adapter. The software component adds Ethernet frames to point-to-point protocol (PPP) packets received from the guest VPN adapter and removes Ethernet frames from packets received from the virtual network adapter.

Abstract: A network firewall is disclosed that operates between a virtualized environment and the processing system that provides the virtualized environment. The network firewall filters network traffic generated by and destined for program components executing in the virtualized environment. The network firewall can be located in a hypervisor, a flow steering engine, or at another location between the virtualized environment and the processing system. The network firewall utilizes a firewall policy that can be shared with a network firewall on the processing system that filters network traffic originating at or destined for the processing system. The network firewall can filter network traffic based upon a unique identifier assigned to a virtualized environment, upon port numbers assigned to program components in a virtualized environment, or upon profiles assigned to network interfaces. The network firewall can also filter loopback traffic between a guest operating system (OS) and a host OS.

Abstract: Technologies are disclosed for providing compatible network resources to program components executing in a virtualized environment. Virtual network adapters are created in a virtualized environment that correspond to network interfaces present on a host processing system. A virtual network interface is created in the virtualized environment and exposed to program components executing in the virtualized environment. Network packets are routed between the program components executing in the virtualized environment, the virtual network interface, the active virtual network adapter, and the network interface on the host processing system corresponding to the active virtual network adapter. Network control messages generated by program components executing in a virtualized environment are intercepted and forwarded to a host processing system for processing.

The identification module may also have a tip guide, configured to receive a tip of the shank of the existing key. The tip guide may have a slot that exposes a tip end of the shank. The identification module may also have an imaging assembly configured to capture an image of the tip end through the slot.

Abstract: A transaction classification system obtains a data set including first data associated with a first characteristic and second data associated with a second characteristic. In response to obtaining the data set, the system uses a classification model to generate a classification by classifying the first data into majority data and the second data into minority data. From the classification and using the classification model, the system determines a cost. The system modifies the classification model based on this cost to generate an updated classification model. The system uses the updated classification model to re-classify a subset of the first data into the minority data and a subset of the second data into the majority data.
