Abstract: L'invention concerne une attelle de cheville permettant de soutenir confortablement la cheville d'un utilisateur par inhibition d'un mouvement entre le pied et la jambe inférieure de l'utilisateur. L'attelle de cheville est constituée d'un matériau stratifié drainant l'humidité au niveau des parties jambe et pied et améliorant le confort pendant des activités sportives. Les parties jambe et pied sont combinées avec des renforts central et latéral supportés dans des pochettes de la partie jambe, de manière à conférer une stabilité centrale et latérale à la cheville. Une unité de bandage est utilisée également pour améliorer la stabilité et elle comprend deux bandes conçues dans le même morceau de matériau stratifié que la partie pied et s'étendant vers le haut à partir de la partie pied de manière à se croiser sur la cheville et à se fixer sur la partie jambe. Le fait de construire les bandes dans le même morceau de matériau que la partie pied présente un caractère avantageux en ce que des éléments de fixation ne sont plus nécessaire, en ce que le matériau ne se chevauche plus et en ce qu'il est possible d'utiliser l'attelle de cheville avec une chaussure standard.

Abstract: A synchronized data transfer system (200) including storage processor nodes (103), a backbone communication switch 101, multiple titles subdivided into subchunks (113a) - (113e) and distributed across the nodes, a user process (207) executed on a first node (201), a transfer process (215) executed on a second node (203), and a management process (219) executed on a management node (205). The user process sends a timestamped read request to request a corresponding subchunk. The transfer process sends a message to the management process for each received read request, where each message identifies source and destination nodes. The management process broadcasts transmit commands to initiate sequential transmit periods, receives the messages, and selects from among the received messages to ensure that each node sends or receives only one subchunk during each transmit period. The management process sends a transmit request for each selected message, and the transfer process sends a subchunk identified by a transmit request in response to the transmit command.

Abstract: An automatic tank cleaning system includes a water recycling unit having a weir therein and a conically-shaped bottom, a cutting box having a portable weir therein, a hydrocyclonic separator, and a mud tank. Tank slop is pumped from the mud tank to the water recycling unit where solids collect at the bottom. The solids are removed and collected in the cutting box. Water in the recycling unit may be pumped through the hydrocyclonic separator. Solids removed by the separator are collected in the cutting box and the water is directed into a clean water compartment defined by the weir within the recycling unit. Water in the cutting box is collected by the portable weir therein and pumped to the clean water compartment. Water from the clean water compartment is pumped to one or more rotary jet heads within the mud tank. Overflow from the water recycling unit may be directed to the cutting box. A chemical inductor may be used to add cleaning chemicals to the water prior to being directed through the wash nozzle.

Abstract: Different papers known in prior art develop only moderate resistance to fats or contain fluorocarbon compounds or chromium complexes in the mass or in an impregnating liquor in order to develop great fat and oil penetration resistance. Said fluoride or chromium compounds represent substances that are known to be or at least seriously suspected of being unhealthy. Hence, the aim of the invention is to create a paper that is free from unhealthy components while being provided with great fat and oil penetration resistance, being easy to print, and being recyclable. Said aim is achieved by obtaining great fat and oil penetration resistance by using a paper that is made of thoroughly ground fiber materials and is glued with alkenyl succinic anhydride in the mass during impregnation inside or outside the papermaking machine with an impregnating liquor containing polyvinyl alcohols, ethylene-vinyl alcohol copolymers, polyvinyl butyrals, carboxymethylcellulose, gelatin, alginates, galactoglucomannans, and/or starch derivatives, polyvinyl alcohol and gelatine being preferred.

Title: Tumor grading from blood volume maps
Inventor: BJORNERUD ATLE
IPC: A61B5/0275
Filed: 2007-03-08
Granted: 2014-07-08
Abstract: An embodiment of the invention is to make possible a non-invasive grading of a tumor based on parameters determined from a frequency distribution (histogram) of values in a map representing cerebral blood volume (CBV) or cellular metabolism in the tumour. The method is especially applicable to brain tumors such as gliomas where histological grading is difficult. The invention provides a precise and consistent grading since it relies on values selected from the whole tumor (not just from hot spots); since it takes the diversity or heterogeneity of the vascularization into account by analyzing the frequency distribution (not just a mean value); and since it involves and allows for a more automated procedure wherein any subjective contributions from human operators is not critical to the resulting grading. CBV maps may be obtained by perfusion imaging using MRI or CT scanning. Cellular metabolism maps may be obtained from a glucose metabolism map obtained by positron emission tomography (PET).
