Abstract: Packaging in the form of disposable,  low cost bags for cooked foods, such as chicken, fish, seafoods and hot baked specialties like pizza maintain the food in a hot crisp and appetizing condition until consumed with little or no sogginess occurring due to being in contact with water vapor/steam,  condensate or residual cooking oils/fats.   The bags have a nonlaminated multi-ply film composite consisting of at least a nonporous outer ply and an inner porous ply as a liner.  The plies are spaced so as to provide a gap in the form of enclosed fluid reservoir for collecting and separating fluids from the food for maintaining crispness with little back flow of condensate and oils to the food compartment.  Special materials and pads for absorption and retention of such fluids may be eliminated.

Des première (130) et seconde (140) valeurs d'état de caractéristiques correspondant aux données transitoires pour des périodes choisies au cours du cycle d'essai sont identifiées (150). Des premières et secondes valeurs de taux de variation (160) correspondant à la modification des états de caractéristiques aux périodes choisies sont alors calculées. Une valeur de constante de temps (170) est ensuite calculée par application de l'intervalle de temps et desdites première et seconde valeurs de taux de variation (160) à une fonction constante de temps. Une valeur de condition d'état stable prévue (180) est calculée ensuite par application de la seconde valeur de taux de variation (160), de la seconde valeur d'état stable (180) et de la valeur de constante de temps (170) à une fonction de condition d'état stable prévue (180). Cette valeur de condition d'état stable prévue est comparée à une valeur prévue précedemment calculée (200). La différence entre ces deux valeurs de condition d'état stable est alors comparée à une valeur seuil (210) afin de déterminer si une prévision satisfaisante de la condition d'état stable a été obtenue (220).

Abstract: A safety cover which securably and reliably locks the tip of a cannula in an interior chamber within the safety cover. The cover comprises an elongate body having the interior chamber and an axial through hole which extends along the entire length of the body, through the interior chamber and through which the cannula is slidably received. Displacing elements are positioned within the interior chamber, each of which includes a hole for receiving said cannula therethrough, and which displaces upon retraction of the tip of said cannula, thereby preventing subsequent advancement of said cannula tip. In a first embodiment the displacing elements are annular rings. In a second embodiment, the elements are rigid balls having through holes. In a third embodiment, the displacing elements are a pair of conical elements, one of which is spring biased, each of which includes an offset hole. In each embodiment, it is preferable that the cannula should include a thickened rib adjacent to said tip, and the safety cover should correspondingly include an annular section in the rear portion thereof. The through hole extending through the rear portion has a diameter which is smaller than said thickened rib of said cannula whereby the cannula tip may not be retracted from the safety cover.

Abstract: A pulse oximeter sensor (410) with a light source optimized for low oxygen saturation ranges and for maximizing the immunity to perturbation induced artifact. Preferably, a red (112) and an infrared light source (114) are used, with the red light source (112) having a mean wavelength between 700-790 nm. The infrared light source (114) can have a mean wavelength as in prior art devices used on patients with high saturation. The sensor of the present invention is further optimized by arranging the spacing between the light emitter (112, 114) and light detectors (116) to minimize the sensitivity to perturbation induced artifact. The present invention optimizes the chosen wavelengths to achieve a closer matching of the absorption and scattering coefficient products for the red and IR light sources. This optimization gives robust readings in the presence of perturbation artifacts including force variations, tissue variations and variations in the oxygen saturation itself.
