  • Publication number: 20210016037
    Abstract: A tracheostomy guard couples with a patient interface to reduce the risk of occlusion of the patient interface. The tracheostomy guard has features that may prevent accidental disconnection from the patient interface while enabling suction to be applied to a patient. The tracheostomy guard may prevent patient secretions from being communicated with a caregiver in use.

  • Publication number: 20200106604
    Abstract: In one embodiment, an apparatus captures a memory dump of a device in a sandbox environment executing a malware sample. The apparatus identifies a cryptographic key based on a particular data structure in the captured memory dump. The apparatus uses the identified cryptographic key to decrypt encrypted traffic sent by the device. The apparatus labels at least a portion of the decrypted traffic sent by the device as benign. The apparatus trains a machine learning-based traffic classifier based on the at least a portion of the decrypted traffic sent by the device and labeled as benign.

  • Publication number: 20190209801
    Abstract: A respiratory humidification system humidifies a flow of respiratory gases supplied to a user. The system can include a main housing that receives a humidification chamber, a heating plate included in the main housing and positioned to contact the humidified chamber and transfer heat to the humidifier chamber, and a heating element that provides heat to the heating plate. The heating element can include a temperature sensor disposed in a central region of the heating element. Disposing the temperature sensor in the central region can reduce a likelihood that conductors of the heating element will cause an incorrect temperature measurement by the temperature sensor.

  • Publication number: 20190022344
    Abstract: This invention relates to connectors to be provided into fluid communication or engagement either directly with, or via a component to be associated with, a terminal end of a breathing conduit. In at least one embodiment, the connector comprises a body having a first end and a second end, and an internal lumen for the passage of gas between the ends. The first end engageable with a terminal end of a conduit or a component to be associated therewith. The second end engageable with another connector. An internal surface of the body at the second end comprises internal connection features for connection with another connector to be received internally therein. An external surface of the body comprises one or more external alignment feature(s) for aligning the connector or another connection into an aligned orientation for connection therebetween.

  • Patent number: 9483659
    Abstract: Some embodiments involve methods and systems for instant personalization security. For example, a social networking system can provide a platform for a user to open applications and/or access external websites. In some cases, an application does not have access to the user's fully identifying profile (e.g., UID or other public information). Instead, the application has access to a pseudonymous profile corresponding to a hashed ID that is generated by the platform and provided to the application. Access to the pseudonymous profile enables the application or an external website to personalize its environment without breaching the security of the platform.

  • Publication number: 20160082218
    Abstract: A connector is described that may be configured to connect between a first tube and a second tube. The connector has an internal component and an external component. The external component has a first end and a second end. The first end has an external taper and an internal coupling face that may be configured to interact with the first tube and the second end may be configured to interact with the second tube. The internal component may be configured to rotate independently to the external component. The external component has a gripping region to aid the user in disconnection of the connector. An attachment mechanism may attach the second tube to the internal component.

  • Publication number: 20140351614
    Abstract: A method of operation of a data storage system includes: providing a standby power source; detecting activity on a communication channel with an upstream re-driver powered with the standby power source; generating a signal-detect output from the upstream re-driver based on the activity; determining a link status with a power control unit based on the signal-detect output, the power control unit powered with the standby power source; and generating a power output from a power supply unit based on the link status, the power supply unit controlled by the power control unit.

  • Patent number: 8875247
    Abstract: A method and system for instant personalization security are provided. The system includes a platform for a user to open applications and/or access web sites. When an application is integrated with the platform, the identification of the application can be combined with the ID of the user and encrypted into a hashed ID. The application does not have access to the user's fully identifying profile (e.g., UID or other public information). Instead, the application only has access to a pseudonymous profile (e.g., the hashed ID, first name, last initial, small profile pictures, and/or other non-fully identifying profile information) of the user. One or more options are then provided for the user to authorize or reject the application to access the user's fully identifying profile. Upon the user's authorization, an access token is provided to the application to access a subset of the user's fully identifying profile.

  • Publication number: 20110078782
    Abstract: Methods, systems, and apparatuses are described for implementations of an Internet protocol (IP) communication device (e.g., an IP phone) that contains a firewall. The IP communication device is coupled between a computer system and a network. A data packet is received at a first port of the IP communication device. The data packet is filtered with the firewall included in the IP communication device. The filtered data packet may be transmitted from a second port of the IP communication device (in modified or unmodified form), or may be canceled based on the filtering. In one implementation, the first port is coupled to the network and the second port is coupled to the computer system. In another implementation, the first port is coupled to the computer system and the second port is coupled to the network.
