Title: Auxiliary structure for connecting connector for use in portable telephone
Inventor: HAYASHI MASAHIKO
IPC: H01R13/52
Filed: 2001-10-25
Granted: 2004-09-28
Abstract: The auxiliary structure for connecting a connector for use in portable telephones of the present invention provides structure for connecting a connector for charging a telephone body and/or performing data communication with the telephone body to a socket exposed from an opening provided on the telephone body. Removably attached to the opening is a connecting auxiliary member which is made of softer material than the one used for a casing of the telephone body. The connecting auxiliary member is formed with an insertion hole for the connector to be fitted into and formed with a guide face for guiding an end portion of the connector to a position of engagement with the socket.      Accordingly, when the connector is connected to the socket of the telephone body, the end portion of the connector can easily be engaged with the socket, and the connector is unlikely to be damaged.

Abstract: Cette invention se rapporte à un dispositif à disque optique, qui est capable d'empêcher toute erreur d'enregistrement ou toute erreur d'effacement sur d'autres surfaces d'information que la surface d'information en cours d'enregistrement, pendant une opération d'enregistrement sur un disque optique comportant plusieurs couches de surfaces d'enregistrement. Une unité de contrôle de focalisation surveille toute augmentation des signaux d'erreur de focalisation, ou une unité de contrôle de quantité de lumière de réflexion contrôle toute réduction de la quantité de lumière de réflexion ou détecte les couches déplacées des surfaces d'information pendant l'enregistrement. Sur la base des résultats de ce contrôle et de cette détection, une unité de commande d'intensité de lumière abaisse l'intensité d'un faisceau lumineux à un niveau d'intensité de reproduction. En outre, lors de l'enregistrement des signaux sur plusieurs couches de surfaces d'enregistrement, l'unité de commande d'intensité de lumière abaisse l'intensité de lumière temporairement à un niveau d'intensité de reproduction et déplace ensuite une couche dont la trace a été gardée par la focalisation d'un faisceau lumineux, avant que l'intensité du faisceau lumineux soit à nouveau augmentée à un niveau d'intensité d'enregistrement.

Title: Method and system for electronic commerce
Inventor: SKOG BENGT ROBERT
IPC: H04W8/20
Filed: 2000-02-25
Granted: 2005-09-20
Abstract: The present invention relates to a method and a system for electronic commer ce as well as a method for checking that a buyer has electronically registered a purchase before delivery of a purchased merchandise. A problem is to secure who the buyer (SBS) is without him or her having established a relationship in advance with the seller. The invention solves the problem by letting the seller offer his/her merchandise from an application (AP1-AP3) in an interna l packet data network (CSN). The packet data network is connected to a GSM- network. The buyer (SBS) is provided with a mobile terminal (MS), and to activate it, he/she gives a code. A session with the application can be set up only from a mobile terminal, and the application then receives information about the identity of the terminal. With reference to this identity, the application sends an order back to the GSM-network. According to one embodiment, the order means that a payment order shall be registered in a payment node, which is controlled by the operator of the GSM-network, for later charging of the buyer. According to another embodiment, a given accoun t number is checked.

Abstract: A method and system are provided to permit a network operator to capture transaction data relating to transactions between a subscriber (16) and a service provider that are conducted via a communications network established by the network operator, such as a cable television network (12). In operation, the subscribers are provided with information relating to items offered by one or more service providers. The subscriber can transmit a purchase order. A headend (14) of the communications network receives and analyzes the purchase order to capture transaction data. If the service provider is different than the network operator, the headend also relays a copy of the purchase order to the third party service provider such that the purchase order can be filled. Since the network operator has captured information relating to the purchase order, however, the network operator can charge the service provider and/or the subscriber for utilizing its network to facilitate the transaction.

Abstract: This disclosure provides an improved system for culturing human pluripotent stem cells. Traditionally, pluripotent stem cells are cultured on a layer of feeder cells (such as mouse embryonic fibroblasts) to prevent them from differentiating. In the system described here, the role of feeder cells is replaced by components added to the culture environment that support rapid proliferation without differentiation. Effective features are a suitable support structure for the cells, and an effective medium that can be added fresh to the culture without being preconditioned by another cell type.  Culturing human embryonic stem cells in fresh medium according to this invention causes the cells to expand surprisingly rapidly, while retaining the ability to differentiate into cells representing all three embryonic germ layers. This new culture system allows for bulk proliferation of pPS cells for commercial production of important products for use in drug screening and human therapy.
