Title: Improved culture of stem cells
Inventor: BERGENDAHL VEIT
IPC: C12N5/0735
Filed: 2008-01-17
Abstract: While culture medium and systems have been described that permit the culture and proliferation of human embryonic stem cells in feeder free and animal product free conditions, these conditions will not readily support cloning of an embryonic stem cell culture meaning, at least here, the initiation of a sub-culture using one or a very few originating cells. It has been found here that a class of small molecules that are inhibitors of kinase enzymes will increase the efficiency of cloning of stem cell cultures sufficiently to make such cloning practical in the defined medium and in other media as well.

IPC: C12Q1/68
Filed: 2007-02-05
Abstract: The invention relates to a method for determining mastitis resistance in bovine subjects, wherein mastitis resistance comprise resistance to both sub-clinical and clinical mastitis. In particular, the method of the invention involves identification of genetic markers and/or Quantitative Trait Locus (QTL) for the determination of mastitis resistance in a bovine subject. The determination of mastitis resistance involves resolution of the specific microsatellite status. Furthermore, the invention relates to a diagnostic kit for detection of genetic marker(s) associated with mastitis resistance. The method and kit of the present invention can be applied for selection of bovine subjects for breeding purposes. Thus, the invention provides a method of genetically selecting bovine subjects with mastitis resistance, thereby yielding cows less prone to mastitis.

Title: Wireless communication method and system for controlling data bit rates to maintain the quality of radio links
Inventor: MILLER JAMES M
IPC: H04B17/40
Filed: 2004-02-11
Abstract: A wireless communication method and system for controlling the current data bit rate of a radio link (RL) to maintain the quality of the RL.  The system includes a core network (CN), a radio network controller (RNC) and at least one wireless transmit/receive unit (WTRU). The RL is established between the RNC and the WTRU. The RNC establishes a guaranteed data bit rate, a maximum data bit rate and a current data bit rate associated with the RL. When the RNC senses an event which indicates that the quality of the RL has substantially deteriorated, the RNC reduces the value of the current data bit rate. Then, in a recovery process, if a similar event does not occur during an established waiting period, the RNC restores the current data bit rate back to the maximum data bit rate.

Filed: 2008-03-06
Abstract: Un produit de multiplication scalaire sur courbes elliptiques mettant en jeu un scalaire et un point de base est déterminé d'une façon qui sert de contre-mesure aux attaques par canal latéral. Une stratégie de fragmentation de clé appelée fragmentation par addition utilisant une division met en jeu la sélection d'un entier aléatoire et la détermination d'un quotient entier et d'un reste par la division du scalaire par l'entier aléatoire. Le produit peut ensuite être exprimé en tant que somme de multiplications scalaires, qui peut être évaluée à l'aide d'une combinaison d'un procédé de fenêtrage à séquence fixe avec le procédé d'entrelacement connu. Lorsque le quotient entier et le reste sont impairs, des collisions majeures peuvent être évitées lors de la détermination du produit. En conséquence, l'entier aléatoire qui détermine si ou non le quotient entier et le reste sont impairs peut être soumis à un certain contrôle.

Patent CA-2695536-A1 (CA)
Inventor: TAKEDA SHIRO
IPC: A45D40/00
Filed: 2009-01-14
Abstract: A mechanism for opening and closing an opening portion is disclosed.  The mechanism can simply and reliably open and close the opening portion without requiring a spring but using a simple mechanism and can stably maintain the closed state of the opening portion. When the opening portion is closed by a lid, with the head end side of the opening and closing member being protruded from the opening portion, the head end of the opening and closing member makes contact with the surface of the lid which faces the inner side of the opening portion, causing the lid to rotate about one end thereof which is rotatably supported by a rotation supporting shaft. This changes the state of the opening portion from the closed state to the opened state. When the head of the opening and closing member retracts into the opening portion from the state in which the opening and closing member is protruded from the opening portion, the protrusion of the opening and closing member will be made to engage the head end of a wound section of the lid, causing the lid to rotate about the one end of thereof which is rotatably supported by the rotation supporting shaft. This changes the state of the opening portion from the opened state to the closed state.

Abstract: A system for connecting supply power to a motor control center pull-out (16) subunit with moveable supply power contacts (4S,48,50). After a motor control center subunit is secured into a motor control center compartment, the supply power contacts (46,48,50) may be advanced to engage supply power buses (88,90,92).
