Abstract: Tilt and swivel adjustment of a flat panel display including detents for landscape and portrait positions and a kickout feature for preventing contact between the flat panel display and its base. A stand for the display includes a neck member coupled to the base member and a riser member which is slidable with respect to the neck member. The display is mounted to an upper portion of the riser member via a swivel apparatus which allows a user to pivot the display between landscape and portrait orientations. The swivel apparatus includes a cam and corresponding ramp. When the display is pivoted between the portrait and landscape orientations, the cam and ramp cause the display to be tilted with respect to the stand such that a lower portion of the display is tilted away from the base member, thereby preventing contact therebetween. The swivel apparatus includes a bearing member which is mounted between the display and a portion of the swivel apparatus which is pivotable with respect to the display.

Abstract: The humidity and/or temperature of a gas sample is monitored so that these system parameters can be accounted and/or actively monitored and controlled. In one embodiment, a gas analyzer system (10) includes an input flowline (12) for receiving a sample stream from a patient respiratory circuit via a patient input module (14), an analyzer instrument (16) for obtaining composition information regarding the gas sample, a humidity sensor module (18) containing a temperature sensor (40) and a humidity sensor (42), and a vacuum pump (22) for drawing the gas sample through the analyzer system (10). A processor (28) receives information from the analyzer instrument (16) and the humidity sensor module (18) and determines composition information regarding the gas sample based on such inputs. The analyzer system (10) thereby allows for improved composition measurements and for monitoring the humidity of the gas sample to stay within specifications or preferred operating ranges of certain analyzer instruments.
