Publication number: 20050054611Abstract: The nutritional deficiencies which constitute a serious side-effect of intestinal cleansing procedures can be alleviated or entirely avoided by a composition and method according to the present invention, wherein a complex carbohydrate is administered to the patient in a form and an amount which gives a blood glucose response similar to that following a normal meal, and stabilizes the blood glucose level above 3.5 mmol/l, preferably above about 4 mmol/l, thus preventing hypoglycaemia. The composition and method is suitable for all patients, but in particular for weakened, elderly or diabetic patients. The composition and method significantly improves the well-being of the patients, and does not reduce the cleansing effect achieved by conventional intestinal cleansing preparations or procedures, and has no known side effects. The preferred complex carbohydrate is native corn starch, and the composition may also include a simple carbohydrate, e.g. sucrose.Type: ApplicationFiled: September 12, 2003Publication date: March 10, 2005Inventors: Mats Lake, Ulf Smith, Mette Axelsen, Eva Olausson

Patent number: 6551912Abstract: On a semiconductor die, a conductive layer is formed by first attaching a semiconductor wafer to a support wafer, then cutting the semiconductor wafer into dies, and finally depositing a conductive layer on the sides of the dies. The conductive layer is preferably a metal layer, which extends into the support wafer, which ensures that, when the support wafer is removed, the conductive layer extends all the way over the sidewall of the semiconductor die. The method allows the simultaneous application of the conductive layer to many dies. The conductive layer reduces the resistance for currents in the radio frequency range flowing close to the edges of the die due to the skin effect.Type: GrantFiled: April 26, 2001Date of Patent: April 22, 2003Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Torkel Amborg, Ulf Smith

Patent number: 6400252Abstract: A resistor has a resistor body of polycrystalline silicon and electric contact regions arranged on and/or in the resistor body, so that a resistor part is formed between the contact regions, which gives the resistor its resistance. The material in the resistor body is doped with for example boron to define its resistance. To give the resistor a good long term stability the resistor part is protected by one or more oxide based blocking layers produced from transition metals. These blocking layers can prevent movable kinds of atoms such as hydrogen from reaching the unsaturated bonds in the polysilicon. Such movable kinds of atoms can for example exist in passivation layers located outermost in an integrated electronic circuit in which the resistor is included. The blocking layers can be produced from layers having 30% titanium and 70% tungsten, which are oxidized using hydrogen peroxide.Type: GrantFiled: February 14, 2000Date of Patent: June 4, 2002Assignee: Telefonaktiebolaget LM EricssonInventors: Ulf Smith, Matts Rydberg

Patent number: 6313728Abstract: A resistor has a resistor body of polycrystalline silicon and electric terminals arranged on and/or in the resistor body. A resistor portion is thus formed between the terminals, which gives the resistor its resistance. The material in the resistor body is doped with for example boron. In order to block unsaturated silicon bonds in grain boundaries to a sufficient extent and thereby give the resistor a good long-time stability, fluorine atoms are added to the material. They are added in such a high concentration that all of the otherwise unsaturated bonds are coupled to fluorine atoms. Further, it is provided in the manufacture of the resistor that the concentration is maintained at the originally high value. When ion implanting dopants and fluorine atoms it can be accomplished by performing an annealing after implanting dopants at a high temperature and then a further annealing operation at a low temperature after the subsequent implantation of fluorine.Type: GrantFiled: September 20, 2000Date of Patent: November 6, 2001Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Ulf Smith, Matts Rydberg
