Damper sealing strip

A sealing strip (10) for a vertically disposed damper (12) for the passage of air from a source to an output having a plurality of pivotal generally planar vanes (15) with a groove (27) at one periphery of the width thereof and a projecting flange (25) at the other periphery of the width thereof, each flange interfitting with the grooves of an adjacent vane when the damper is closed, the sealing strip having an attachment portion (30) of generally U-shaped configuration for engaging the flange of a vane, the generally U-shaped configuration having a pair of spaced legs (35, 36), and a sealing lip (46) projecting from one of the legs for contacting the planar engaging portion (48) of an adjacent vane during closure of the damper.

Sealing strip for damper system

A signal filter method and apparatus for removing portions of a signal indicative of erroneous data, an exemplary apparatus including means for receiving the signal, means for adjusting a threshold by increasing the threshold a first predetermined amount when the signal is in a predetermined relationship with the threshold and for decreasing the threshold a second predetermined amount when the signal is in a second predetermined relationship with the threshold, and means for comparing the signal with the adjusted threshold and for transmitting the signal if the signal bears a first predetermined relationship to the threshold. Disclosed herein are digital and analog implementations of the signal filter method and apparatus, particularly suited for use with catheter-type oximeter apparatus.
