Abstract: The golf club scrubber is a device that clamps on to a pipe and holds two brushes at convenient angles and height so that golfers can clean (scrub) their golf club faces on them. Water and a cleaning solution is provided for cleaning the clubs by way of spray bottles and/or the use of a pail. The person cleaning the golf club first wets the face of the club using spray bottles or by dipping it into a pail of water and then scrubs the club face against the angled brush or brushes. The dirty water drips from the brush on to the ground (crushed rock) past the pail of clean water. This process can be repeated as many times as required to clean the club head, then a final spray rinse can be given before the club head is dried.

Abstract: Un système infographique génère un modèle tridimensionnel d'un objet de manière interactive sous la commande d'un opérateur. Un modèle initial de l'objet à modéliser est affiché à l'opérateur, illuminé à partir d'une direction d'illumination particulière et projeté sur un plan d'image. L'opérateur peut actualiser l'ombrage d'un pixel sur le plan d'image et, sur la base de l'ombrage actualisé, le système infographique génère un vecteur perpendiculaire actualisé pour le pixel actualisé, lequel identifie la perpendiculaire de la surface de l'object projeté sur le pixel actualisé. L'utilisation du champ du vecteur perpendiculaire actualisé et d'un champ de hauteur, lequel représente la hauteur de la partie respective de l'objet projetée sur les pixels respectifs du plan d'image, permet au système infographique de générer une valeur de hauteur actualisée pour le pixel actualisé, actualisant ainsi le champ de hauteur. Le champ du vecteur perpendiculaire actualisé et le champ du vecteur actualisé définissent le modèle actualisé de l'objet, lequel correspond à la forme actualisée de l'objet tel qu'elle est actualisée sur la base de l'ombrage actualisé. Le système infographique peut alors afficher à l'opérateur une image de l'objet telle qu'elle est définie par le modèle actualisé. Si le modèle actualisé est satisfaisant, le système infographique conserve le modèle actualisé comme modèle final. En revanche, si le modèle actualisé n'est pas satisfaisant, l'opérateur peut à nouveau actualiser l'ombrage et permettre au système infographique de générer un autre champ de vecteur perpendiculaire actualisé et un autre champ de hauteur actualisé, afin de générer ainsi un autre modèle actualisé de l'objet. Les opérations peuvent être répétées jusqu'à ce que l'opérateur détermine que l'objet est satisfaisant.

Title: Method and device for calculating dialysis efficiency
Inventor: STERNBY JAN
IPC: G01F/
Filed: 1998-06-02
Abstract: A method and apparatus for calculating the mass of a composition in a fluid volume or efficiency of exchange of said composition with an exchange fluid, especially urea in the body of a dialysis patient.  Calculations are based on total mass of urea in the body. The concentration c d of urea in the effluent dialysate is measured, and the total removed mass U of urea is calculated by integrating the product of the urea concentration c d and the dialysate flow Q d. The momentary relative efficiency of the removal (K/V) is determined essentially by calculating the slope of the logarithm of the concentration curve and the momentary mass is determined therefrom. Then, the pre-treatment mass of urea in the body can be determined very accurately. Moreover, the momentary relative efficiency in any point is determined by using the removed urea U. The dialysis dose is calculated by integrating the momentary efficiencies.

IPC: H04L47/30
Filed: 2000-03-20
Abstract: A system and method for reducing the overall cell loss ratio in switching networks, while maintaining service fairness during periods of traffic congestion. The method includes controlling data flow in a data switching system having an ingress and an egress. The method commences by detecting an egress congestion condition. Data flow in the switching system is then decreased in response to the detected egress congestion condition. If an ingress congestion condition is then detected, data flow in the switching system is increased. The switching system has an ingress and an egress, and includes a switch fabric for switching data units from the ingress to the egress. An egress card has a first feedback link to the switching fabric. The egress card has an egress congestion monitor for detecting an egress congestion condition and for notifying the switch fabric, through the first feedback link, to decrease data flow to the egress upon detecting the egress congestion condition. An ingress card has an alternate forward link to the switch fabric, and an ingress condition monitor for detecting an ingress congestion condition and for notifying the switch fabric, through the alternate forward link, to increase data flow from the ingress upon detecting the ingress congestion condition.
