Abstract: In an example, a ventilator includes an outer container containing liquid, an inverted container submerged in the liquid to provide inverted container space between a closed top and an inner container liquid level; gas supply line to supply breathing gas to the inverted container space; and inhalation line having an inlet in the inverted container space to provide breathing gas to patient. The inverted container moves upward from a first elevation when the inverted container space reaches a hydrostatic delivery pressure and volume of the inverted container space increases. The inverted container stops moving upward and the gas supply line stops supplying when the inverted container reaches a second elevation above the first. Based on a breath demand signal or preset timing, the inhalation line opens to permit flow of breathing gas to the patient at the hydrostatic delivery pressure, lowering the inverted container due to lost buoyancy resulting in sinkage.

Abstract: An embodiment includes a method to increase the efficiency of security checkpoint operations. A security checkpoint kiosk serves as a Relying Party System (RPS). The RPS establishes a secure local connection between the RPS and a User Mobile-Identification-Credential Device (UMD). The RPS sends a user information request to the UMD, via the secure local connection, seeking release of user information associated with a Mobile Identification Credential (MIC). The RPS obtains authentication of the user information received in response to the user information request. The RPS retrieves user travel information based on the user information. The RPS determines that the user travel information matches the user information. When the user travel information matches the user information, the RPS approves the user to proceed past the security checkpoint kiosk.

Abstract: In an example, a patient using a user mobile-identification-credential device (UMD) requests the patient's medical record from a medical office using a relying party system (RPS). The RPS requests identification information of the patient from the UMD and receives, based on consent of the patient, some or all patient identification information associated with a mobile identification credential (MIC) previously provisioned to the UMD an authorizing party system (APS). The RPS receives verification of the received patient identification information, uses the verified user ID information to verify or not verify the identity of the patient, and verifies the identity of the patient before granting the request to provide the medical record to the patient. The patient has the option of releasing part or all of the medical record to a third party. In one embodiment, the patient stores the medical record with a service provider and authorizes, in advance, certain medical personnel to have access to it.

Abstract: Systems and methods are described, and an example system creates a transaction between a biometric station and a user in a group of users. Transaction includes establishing for the user, a ground-truth identity, capturing an image of the user in the biometric station, making a first determination of whether the image is sufficient for identification of the user. When the image is sufficient, the transaction derives biometric information from the image, converts the biometric information into a generic-form biometric information, agnostic of how the biometric information was obtained, and generated hashed user data by applying a hash function to the generic-form biometric information. The transaction makes a second determination, based on the hashed user data, of whether the user is represented in a gallery of sample images. The transactions are repeated for other users in the group.
