Abstract: The disclosed techniques relate to an apparatus including: a pump body, an occlusion bed; and a rotor. The rotor includes: a shaft body; a roller body slidably mounted to the shaft body; and a lock mechanism selectively positioned between a first position and a second position. In the first position, the lock mechanism engages with the roller body to lock the roller body at a first roller body position relative to the shaft body where the one or more rollers can compress tubing disposed in the apparatus against the occlusion bed with a first level of compression. In the second position, the lock mechanism disengages the roller body so the roller body can slide along the track relative to the shaft body to a second roller body position configured to cause decreased or no compression of the tubing against the occlusion bed by the one or more rollers.

Abstract: The invention provides improved modular gun stocks and their methods of manufacture. Advantageously, gun stocks of the invention require fewer parts than conventional gun stocks. The lower stock supports of the improved modular gun stocks can be removed and replaced in multiple ways so that a variety of gun stocks can be created as desired. The invention also eliminates the undesirable rattling noise that modular gun stocks often have after assembly.

Abstract: The full face flexible oxygen mask for use with flight helmets includes an elastic face seal with an oronasal cone that seals around the nose and mouth of the wearer, and flexible sealing flaps along the perimeter of the face seal to adapt the face piece of the mask to seal against the surface of a flight helmet. The mask face piece has two large sealing surfaces or channels down each side of the mask that overlap and flex to adapt to seal to a variety of flight helmets. The top of the face seal has an inner and outer flap that work together to seal the exposed face visible between the sides of the flight helmet.

Abstract: A mask and harness system for use in providing breathing oxygen and protection from pollutants for the eyes and respiratory system as might be encountered in high altitude aviation environments. In one preferred embodiment, the mask system has a face seal, a soft flexible lens, a pneumatically-actuated harness, and a regulator with microphone to control the flow of oxygen and to facilitate communications in aircraft flight decks and other aircraft compartments. The system is designed for required five-second donning with one hand and because of the flexible lens, is capable of storage in the relatively preferred on crowded flight decks. It is connected to an oxygen source and, optionally, with aircraft communications. The regulator controls the flow rate of oxygen to the wearer based on altitude and physiological requirements. The regulator includes a valve for purging the condensation-prone moist gases from the lens area and provides positive pressure in the mask.

Abstract: An optical orientation piece for use with reflector telescopes for the rotation of the viewed image at the eyepiece to allow for land based viewing. The orientation piece comprises a housing with standard optical interfaces to allow it to be inserted between the telescope focusing mechanism and the eyepiece. The orientation piece design allows it to be rotated about the axis of the telescope drawtube to a point at which the reflected image appears properly oriented to the users real world viewing. The device is capable of rotating the image to any desired angle.

Abstract: An automated system for post-discharge follow-up of discharged patients automatically contacts each discharged patient after a predetermined period of time. The discharged patient is presented with a series of questions and an answer to each question is collected and analyzed. If the analysis detects an anomaly, an alert message is sent to a predetermined contact person to permit an investigation to be conducted.

Abstract: A valve assembly (20) including a valve body (24) and a position-indicating knob assembly (28) is provided wherein the assembly (28) indicates three different valve positions, namely valve closed, partially opened and full open positions. The preferred assembly (28) includes a rotatable knob (44) including a viewing port (80) therein, together with an indicator ring (40) having three differently colored regions (62-66) corresponding to the different valve positions. A coupling assembly (42, 80, 70, 90) operably couples the knob (44) and indicator (40) so that the individual colored regions (62-66) come into view through the port (80) when the valve body (24) reaches the different valve positions. The assembly (28) is particularly useful with valves requiring greater than one revolution between valve closed and valve full open positions, such as valves used in conjunction with emergency oxygen cylinders on aircraft.

Abstract: A compact, lightweight latch (38) especially adapted for use with an emergency deployment oxygen mask container (20) is provided which is made up of a minimum of parts and which can be delatched in multiple ways. The latch (38) includes a latch assembly (40) designed to be mounted in the oxygen mask container box (22) and a cooperating latch pin (44) secured to a cover (24). The assembly (40) has a primary latch body (46) supporting a diaphragm (48), latch member (50) and shiftable piston (52); the latch member (50) includes a plurality of laterally displaceable, hook-shaped locking legs (86) configured to interfit with latch pin (44). The piston (52) is shiftable in opposite axial directions within latch member (52), and cooperating surfaces on the member (50) and piston (52) serve to positively displace the latching legs (86) in response to piston movement. During pneumatic operation, the piston (52) is shifted within latch member (50) under the influence of diaphragm (48).

Abstract: A modular, dropout passenger oxygen mask container (10) is provided which allows the container (10) to be used in a variety of different aircraft mask deployment areas presenting respective openings (20) without container modification. The container (10) includes a box (14) having an openable lid (16) and a universal series of component mounts (36-54) in the walls thereof which allow attachment of physically separate oxygen inlet, lid latch and mask oxygen valve components (72,74,76) at multiple locations within the box (14). The components (72,74,76). A separate cover (18) is attached to the lid (16) and is designed to mate with a specific opening (20); preferably, the cover (18) is affixed to lid (16) by means of Velcro (68,70).

Abstract: Inflatable harness respiratory apparatus (10) is provided having an improved comfort control assembly (16) allowing reduction in the engagement force exerted by the fitting surface (20) of the mask (12) against the face of the user. The mask (12) is equipped with an inflatable harness strap element (26) having terminal ends (28, 30) supported on stationary, tubular mask mounts (36) via housing assemblies (38). In one embodiment, the terminal ends (28, 30) are releasably locked onto the mounts (36) by means of locks (52), but are axially shiftable along the length of the mounts (36) in order to adjust the effective distance between the fitting surface (20) and the terminal ends (28, 30). An adjustment button (78) may be depressed in order to disengage the locks (52) and permit shifting of the associated terminal end (28, 30). Alternately, an intermediate comfort position is pneumatically achieved by controlled pressurization of an internal cavity (128) within the housing assembly (88).
