Abstract: A shield assembly includes a closing structure configured to be disposed over an opening of an enclosure. The closing structure includes an inner surface configured to face an inside of the enclosure when the closing structure is closed and a finger bracket structure mounted on the inner surface, the finger bracket structure having a bracket and one or more finger gaskets coupled to the bracket. An electromagnetic interference (EMI) shielded gasket disposed along a portion of the opening of the enclosure shields an edge of the opening of the enclosure or a radio frequency (RF) fence bracket coupled to a frame disposed around the opening of the enclosure creates a narrow path between the frame and the closing structure, the narrow path attenuating RF signals passing through the narrow path and shielding an edge of the opening of the enclosure.

Abstract: A door assembly is described. The door assembly includes a door structure that is mounted over an opening of an enclosure. The door structure includes a body that includes a first surface and a second surface opposite to the first surface. The first surface may face an inside of the enclosure when the door structure is closed. The door structure includes a number of finger bracket structures mounted on the first surface. Each one of the finger bracket structures includes a bracket and one or more finger gaskets coupled to the bracket. The finger gaskets of the finger bracket structures may contact enclosure brackets mounted around an edge of the opening of the enclosure when the door structure is closed. A combination of the finger gaskets in contact with enclosure brackets may create an electromagnetic interference (EMI) shield at the edge of the opening of the enclosure.

Abstract: A method for remotely witnessing a medical workflow is provided. The method includes authenticating a clinician at a witnessing device. The method also includes receiving, at the witnessing device, a request to perform a medical workflow. The method further includes determining, at the witnessing device and based at least in part on the medical workflow, that a witness is required to observe the medical workflow. The method also includes initiating, at a witnessing client remotely coupled with the witnessing device, a witnessing session, wherein the witnessing client allows a witness to remotely observe the medical workflow. The method also includes enabling, in response to at least the initiation of the witnessing session, completion of the medical workflow. Related systems and articles of manufacture, including apparatuses and computer program products, are also disclosed.
