Abstract: Selon l'invention, des données concernant des échantillons sont collectées, lesquelles présentent des caractéristiques qui changent au fil du temps et qui sont contenues dans un réseau de conteneurs disposés en une relation spatiale entre eux. Une matrice de cellules est présentée dans une relation spatiale entre les cellules qui correspond à la relation spatiale entre les conteneurs. Une entrée utilisateur est acceptée dans au moins une des cellules de la matrice présentée, afin d'introduire au moins une valeur d'au moins une des caractéristiques qui changent au fil du temps pour au moins un des échantillons qui correspondent à la ou aux cellules de la matrice présentée. Grâce à l'interface utilisateur de la matrice, un utilisateur peut introduire un grand nombre de points de données par minute, en comparaison avec les systèmes classiques dans lesquels un utilisateur peut être appelé à balayer un code-barres, à introduire un indice ou à introduire une position rangée/colonne pour un échantillon avant d'introduire des données. Pour programmer la collecte des caractéristiques des échantillons, on peut également stocker des valeurs passées des caractéristiques des échantillons qui ont été collectées dans une base de données pendant au moins un intervalle de temps passé et stocker des règles dans une base de règles. Ces règles déterminent si une caractéristique d'un échantillon doit être collectée et, si tel est le cas, elles identifient la caractéristique qui doit être collectée, sur la base des valeurs passées des caractéristiques de l'échantillon. Ces règles sont appliquées à des valeurs passées qui sont stockées dans une base de données, afin d'identifier des échantillons cibles devant être collectés et afin d'identifier au moins une caractéristique cible devant être collectée pour les échantillons cibles qui sont identifiés.

Inventor: KOSIOR EDWARD
IPC: B29C48/04
Filed: 2000-09-18
Abstract: A process for preparing food contact grade PET from a waste stream containin g PET and non PET materials is disclosed. The process involves the steps of sorting at least some of the non PET materials from the waste stream, follow ed by dividing the PET containers into flakes of preferable maximum size approximately 10mm, followed by washing the flakes in a hot aqueous medium containing alkaline materials and surfactants, preferably non-ionic, to remo ve particulate and absorbed contaminants from the surfaces of the flakes. This step is followed by de-watering and then drying the flakes to a moisture content of 0.1 % w/w maximum, and more preferably 0.01 % w/w maximum. The ne xt step involves removing absorbed contaminants and moisture by heating and vigorously mixing the flakes under vacuum, preferably 1-10 millibar, more preferably 2-7 millibar and at a temperature less than the melting point of PET, preferably in the range 170-220 ~C for at least 30 minutes, preferably at least 60 minutes. The final step involves melting the flakes in a screw extruder equipped for vacuum processing and extruding the molten material to  form strands that are pelletised.

Abstract: A steerable endoscope has an elongated body (102) with a selectively steerab le distal portion (104) and an automatically controlled proximal portion (104).  The endoscope body is inserted into a patient and the selectively steerable distal portion is used to select a desired path within the patient's body. When the endoscope body is advanced, an electronic motion controller (140) operates the automatically controlled proximal portion to assume the selecte d curve of the selectively steerable distal portion. Another desired path is selected with the selectively steerable distal portion and the endoscope bod y is advanced again. As the endoscope body is further advanced, the selected curves propagate proximally along the endoscope body, and when the endoscope  body is withdrawn proximally, the selected curves propagate distally along t he endoscope body. This creates a serpentine motion in the endoscope body that allows it to negotiate tortuous curves along a desired path through or aroun d and between organs within the body.
