Abstract: Apparatus for heating and humidifying respiratory gases comprise a housing, a gas permeable member and generating material. The housing includes an inlet adapted for connection to a tracheal tube and an outlet adapted for connection to a tube for passing respiratory gases. The inlet and the outlet are positioned so that respiratory gases passing through the housing pass therebetween. The gas permeable member, for example, a conventional heat and moisture exchanger member, is positioned in the housing between the inlet and the outlet and is adapted to exchange heat and moisture with respiratory gases passing through the housing. The generating material, for example, a carbon dioxide absorbing component, is located in the housing between the inlet and the outlet and is adapted to generate water, and preferably heat, available to humidify, and preferably heat, respiratory gases passing through the housing.

Abstract: During electronic film development, an area of conventional photographic film is scanned several times using a single scanning station, and at each subsequent time this scanned area is advanced incrementally along the film with multiple levels of overlap with previous scans. The new image scanned at each new time is aligned to an accumulating image that has been extrapolated to the image at the new time, and then the new image is added to the accumulating image in parametric summations that allow an image to be interpolated to any time free of seams where the scans overlap. The invention further teaches a method of steering the alignment by warping the leading edge of the alignment, and a registration method of aligning multiple images that takes advantage of known fixed alignments between images.

Abstract: A chip carrying socket includes a base and at least one and preferably two cam shafts journaled or supported within the base in a spaced relationship for rotational movement relative to the base. A plate is supported upon the base and extends between the cam shafts. The plate has a plurality of openings formed therein which receive the leads of an IC. In a BGA type IC, these leads are semi-spherical balls which depend from the lower face of the IC. Conductors or pins adapted for connection to testing or operative circuitry are carried by the base and extend into proximity with the leads of the IC as it is supported upon the plate. Each cam shaft engages the plate so as to shift the plate relative to the base causing the conductors carried by the base to forcibly engage the leads of the IC when in one shifted position and causing the conductors to be released from such forcible engagement with the leads of the IC when in a second shifted position. A top located over the base movable between upper and lower positions relative to the base and the underlying plate is provided. The top engages each of the cam shafts to rotate the shafts causing the plate to be shifted between its previously mentioned positions as the top is moved between its upper and lower positions. The top also releases a latch which holds the IC in place, as the top is moved to the lower position. In addition, adjustable locators which serve as a guide for the IC when it is placed upon the plate are provided and may be selectively positioned upon the plate depending upon the accommodating size of the IC and selected position of the IC upon the plate.
