A centrifuge apparatus for separating whole blood into its serum and cell components. The device consists of a small centrifuge cup having a movable bottom wall formed by an upwardly movable piston. The cup is surrounded by a three-tiered ring-shaped container with the two upper tiers each containing a plurality of pockets. The centrifuge cup is spun at a high speed and the whole blood sample in the cup is separated, with excess sample expelled into the lowest tier. The multi-pocketed container is also spun as a centrifuge coaxially with the cup but at a lower speed. The bottom wall piston of the cup and the container are movable vertically relative to the cup by respective cams operated by a common timer-controlled motor. The container moves downwardy and the piston moves upwardly so that when the first multi-pocketed tier is adjacent the top of the cup, the piston is in a position to force the serum component out of the cup and into the tier pockets at this level; when the container moves further downwardly to bring the second multi-pocketed tier adjacent the top of the cup, the piston is in a position to expel the cell components into the pockets at this level.

There is provided a sensor including a housing, where the housing has an opening configured to receive a sensing element; an electric circuit operably connected to the housing, where the electric circuit is configured to detect at least one electrical characteristic across at least one pair of electrodes positioned on the sensing element; at least one gas-moving element in electrical communication with the electric circuit; and a reader in communication with the electric circuit, where the reader is configured to compare information about a gas volume external to the housing with information about a gas volume within the housing.

A ring-shaped cushion for a hearing protector or audio headset. The cushion has a circumferential contact pad for sealing on a wearer's head and an attachment for sealing with an earmuff. The cushion further has a sound insulation tube that inwardly defines an inner space. The sound insulation tube extends between the contact pad and the attachment. The cushion has a ventilation passage that extends entirely through the cushion between an inlet opening in the contact pad and an area outside of the inner space. The cushion may further include one or more physiological sensors to monitor the health of a wearer.

There is provided a fit testing method comprising: providing a respirator donned by a wearer; providing a sensor in electrical communication with a sensing element, where the sensor is configured to monitor a particulate concentration parameter of a gas space within the respirator, and a second particulate concentration parameter of a gas space outside the respirator, where the sensor is attached to the respirator such that the respirator such that the weight of the sensor is supported by the respirator; and providing a reader configured to communicate with the sensor, where the reader is configured to provide a respirator fit parameter based on a comparison of the particulate concentration within the respirator to the particulate concentration parameter outside the respirator.

A method of fit testing includes providing a respirator donned by a wearer, providing an aerosol generator with a known aerosol output parameter, providing an enclosure that is physically supported around the wearer's head, where the aerosol generator delivers aerosol with the known aerosol output parameter that is at least partially contained within the enclosure around wearer's head, providing a sensor in electrical communication with a sensing element, where the sensor is operably connected to the respirator, and where the sensor is configured to monitor a particulate concentration parameter within the respirator, and providing a reader configured to communicate with the sensor, where the reader is configured to provide a respirator fit parameter based on a comparison of the particulate concentration parameter to the known aerosol output parameter.
