摘要:
A composite board for use as backerboard for tile includes outer reinforcement portions and a polystyrene layer disposed between the two outer reinforcement portions, at least one of the outer reinforcement portions being an outer mat fabric reinforcement layer with a mat fabric, and a non-shrinking cement compound saturating and connecting the two outer portions with the polystyrene substrate. A method of installing a composite tile backerboard involves placing the composite board against a fixture protruding from a flat surface, pressing the composite board against the fixture to emboss the features of the fixture on the surface of the composite board, and cutting a hole in the composite board based upon the features of the fixture embossed on the composite board.

The present invention relates to an apparatus and method for controlling access to protected web pages on a web server by using a method of authentication. The method according to the invention is divided into a general method for authenticating the client and a downstream method for granting authorization to access the protected web pages by generating a session ID of which the client is notified after successful authentication, and by inserting the session ID as part of the new request. This ensures that even the links on the protected-access web page are covered and are provided with a session ID to serve as access authorization. The session ID is preferably given a validity date. The present invention fits into the existing browser infrastructure without any alterations being needed for this purpose. The use of a chip card increases the security of the method of authentication.

An improved articulator for monitoring and correcting masticatory surfaces of the upper and lower jaw portions of a dental prosthesis model is provided. The improved articulator includes a frame and two reproduction bodies movably mounted on the frame that are respectively designed to carry an upper and lower jaw portion of a dental prosthesis. Articulation means connected to the reproduction bodies move the bodies three-dimensionally in relation to one another to copy the articulative movements of a patient. Compensation means connected to at least one of the reproduction bodies provides three-dimensional adjustment of a jaw model portion in relation to the reproductive body, when the jaw model is attached to the body.

A method for forming a thin-film transistor gate insulating layer over a substrate disposed in a processing chamber is provided. The method includes: introducing a processing gas for producing a plasma in the processing chamber; heating the substrate to a substrate processing temperature of between 50 and 350° C.; and depositing silicon oxide, silicon oxynitride, or silicon nitride over the heated substrate by sputtering a target assembly at a medium frequency.

The present invention describes a device and a method for performing cashless payments between a customer and a dealer. The advantages of the present invention lie in that payments can be performed over the Internet without implementing special payments commands stored in the customer chip card. It is sufficient to use a normal chipcard with a file structure. Such a file structure can be used in different file system cards and does not depend on the chipcard's operating system. Therefore, the inventive method can be used in a variety of chipcards without implementing special payments commands. The protocol is designed such that per payment only three steps of communication are required.
摘要:
A signal voltage (E) based upon a supply voltage must be converted to a signal voltage (A) with ground reference so as to enable further processing in a logic circuit. A simple level converter comprises a series connection of a MOSFET (T1) connected to the supply voltage; the MOSFET also comprises a resistor (T2). The source terminal of the MOSFET (T1) is located at the potential of the supply voltage. The voltage to be converted is applied between the gate terminal and the source terminal, and the converted voltage occurs at the resistor (T2). The two voltages are each limited by one Zener diode (D2, D1).

Computer-based methods and systems are described wherein at least one content provider, a portal and a user are coupled to a communications network or content delivery network. The content provider provides means for generating information in a markup language and for sending the information to a portal. The portal comprises means for combining information received from one or more content providers and for sending the combined information to the user.
摘要:
A computer program product and programmed method for performing cashless payments between a customer and a dealer via a bank. The invention is embodied in an on-line computerized process between customer and dealer to define the payment method, check the availability frame, issue a voucher to describe the transaction, issue a payment instruction, signature of the issued voucher by the dealer and signature of the payment instruction by the dealer and the customer. In another embodiment, the information is gathered and the voucher and payment instructions are generated off-line. A subsequent on-line process between the dealer and bank transfer the signed payment instruction and signed voucher to the bank where computer coded checks the dealer and customer signature, checks the allocation between payment instruction and voucher, replaces the dealer and customer identity data with information for performance of the payment instruction, and performs the payment instruction and stores the voucher. An advantage of the process is that no sensitive customer data such as account number, credit card number etc. is stored on the customer card and hence misuse by unauthorized persons is minimized. In addition the process serves to define the payment methods required by the customer for mechanical processing and to minimize the risk to the customer upon loss of the customer card. The process also allows customers who do not have a bank account, such as children for example, to have access to an electronic payment means with limited availability frame. The customer card can be either a card with contacts or a contactless card.
摘要:
The voltage (U.sub.DS) on a power MOSFET (1) is compared with a voltage (U.sub.V) derived from the sum of the voltages of a Zener diode (3) and the threshold voltage (U.sub.T) of a second MOSFET (5) to detect a short circuit in a load (2) in series with the power MOSFET (1). When this total voltage is exceeded, the second MOSFET conducts. Its load current is then evaluated as the short circuit signal.
摘要:
A semiconductor component with a power MOSFET and control circuit for controlling the power MOSFET. Both the power MOSFET and the control circuit have separate semiconductor bodies. The semiconductor body of the control circuit is arranged on one of the main surfaces of the semiconductor body of the power MOSFET. The control circuit is electrically insulated from the MOSFET by an insulating layer and mechanically coupled to the MOSFET by means of a bonding layer. The MOSFET is fastened to a cooling body which serves as a heat sink for the semiconductor component. The terminals of the control circuit and the MOSFET are attached to housing connections with leads.
