Abstract: A method for fabricating a layered sorbent film is disclosed. The method includes forming a first sorbent layer by adhering a particulate sorbent material to a first adhesive surface of an adhesive film, the adhesive film further including a second adhesive surface coupled to a sacrificial liner. The method also includes removing the sacrificial liner from the adhesive film by exposure to a release medium, uncovering the second adhesive surface, and then forming a second sorbent layer by adhering the particulate sorbent material to the uncovered second adhesive surface. The method may also include separating a first release liner from the first adhesive surface of the adhesive film, uncovering the first adhesive surface. The sacrificial liner may be sufficiently rigid that while the sacrificial liner is coupled to the second adhesive surface, the first release liner may be removed from the adhesive film without causing mechanical damage.

Abstract: Removable barrier devices (e.g., sleeves) for covering medical scanning devices to reduce the chance of cross-contamination between patients and/or to protect the scanning devices from physical damage. The barrier device can include a cover that has an integrated window for passing optical signals between the scanning device and an external environment.

Abstract: Transport Layer Security (TLS) connection establishment between a client and a server for a new session is enabled using an ephemeral (temporary) key pair. In response to a request, the server generates a temporary certificate by signing an ephemeral public key using the server's private key. A certificate chain comprising at least the temporary certificate that includes the ephemeral public key, together with a server certificate, is output to the client by the server, which acts as a subordinate Certificate Authority. The client validates the certificates, generates a session key and outputs the session key wrapped by the ephemeral public key. To complete the connection establishment, the server applies the ephemeral private key to recover the session key derived at the client for the new session. The client and server thereafter use the session key to encrypt and decrypt data over the link. The ephemeral key pair is not reused.
