Abstract: A controlled access aerosolized particle enclosure for isolation of airborne contaminants includes a frame defining a patient isolation region over a patient bed. A linkage attaches the framed enclosure to a patient treatment vehicle, and a flexible elasticized barrier is suspended by the frame for enclosing the patient isolation region. The barrier is formed from deformable planer sheets of a flexible transparent material and extending adjacent to the patient treatment surface forming a draped edge around the bed or transport. A low pressure source is in fluidic engagement with the enclosure for reducing a pressure within the enclosure below that of ambient surroundings, such that the low pressure source provides a pressure for drawing the elasticized barrier against the patient treatment surface for restricting airborne particle passage from the enclosure to the ambient surroundings, but limits the negative pressure to avoid substantial deformation or collapse of the enclosure.

Abstract: An irradiation method and system for irradiating a target volume, the method comprising: providing thermal neutron absorbing nuclides (such as in the form of a high neutron cross-section agent) at the target volume; and producing neutrons by irradiating nuclei in or adjacent to the target volume with a beam of particles consisting of any one or more of protons, deuterons, tritons and heavy ions, thereby prompting production of the neutrons through non-elastic collisions between the atoms in the path of the beam (including the target) and the particles. The neutron absorbing nuclides absorb neutrons produced in the non-elastic collisions, thereby producing capture products or fragments that irradiate the target volume.

Abstract: The present application discloses a hearing prosthesis configured to alert a user of the presence of sound while operating in a sound awareness mode of operation. When a user of the hearing aid removes the external sound processor and microphone, traditionally, a hearing prosthesis does not produce any audio stimulus. Here, the systems and methods will alert a user to sounds in his or her environment when the external sound processor and microphone are decoupled from the internal components of the hearing prosthesis. In some embodiments, the hearing prosthesis may have an acoustic receiver that is implanted in the recipient. The implanted acoustic detector may be used to detect an aspect of a sound above a threshold level. The threshold may be chosen so the detected sound is a loud sound such as a fire alarm.
