  • Patent number: 7954706
    Abstract: An added level of security is provided for charge card transactions. Upon presenting a charge card number for a purchase, for example, the cardholder receives a message on his cell phone or PDA that a charge authorization request has been received.

  • Patent number: 6835528
    Abstract: A photoresist which has high transparency at a wavelength of 157 nm and which therefore permits a greater layer thickness in photolithographic processes for the production of microchips. The photoresist includes a polymer that is prepared from a first fluorinated comonomer that includes a group cleavable under acid catalysis, a second comonomer that includes an anchor group, and a third comonomer whose degree of fluorination is tailored to the second comonomer so that at least one of the comonomers acts as an electron donor and the others act as electron acceptors in the free radical polymerization. Thus, in spite of a high degree of fluorination, the polymer can be prepared in a simple manner and in high yield.

  • Patent number: 6836440
    Abstract: Two methods check functional capability of electrical connections between address lines of a printed circuit board of a memory module and address line contacts of an integrated semiconductor memory chip mounted on the printed circuit board. Ruptured solder contacts are conventionally examined optically or investigated by electrical resistance measurements; however, the latter do not work in the case of memory modules with a number of semiconductor chips, the pin contacts of which are connected in parallel by the address lines. The methods make it possible to locate interrupted contacts on individual address lines by the indirect use of a write-read access to the semiconductor memory chip, specifically utilizing the misrouting of writing and reading commands produced by defective contact connections.

  • Patent number: 6836219
    Abstract: A sensor device having an incremental encoder and a measuring sensor generating a measuring signal is assigned to two control devices. A synchronization device generates a synchronization signal. A conditioned first measuring signal is generated in the first control device as a function of the measuring signal. A conditioned second measuring signal is generated in the second control device as a function of the measuring signal. The value of the conditioned first measuring signal at a predefined time after the reception of the synchronization signal in the first control device is transmitted to the second control device. The second control device synchronizes the conditioned second measuring signal as a function of the values of the conditioned first and second measuring signals that the signals have at the predefined time after the respective reception of the synchronization signal in the first and second control devices.

  • Patent number: 6836740
    Abstract: A method of determining a relative position of first and second imaging devices includes setting an image of a group of mutually different reference patterns and a basic pattern on an imaging medium, with the second imaging device. Each reference pattern of the group is assigned uniquely to one relative position. An image of at least one test pattern is set over the basic pattern by the first imaging device, for forming a combination pattern. A reference pattern having an area coverage coinciding with an area coverage of the combination pattern is identified from the group of reference patterns. A relative position associated with the identified reference pattern of the group of reference patterns is then identified. A printing form exposer, a printing unit, a printing unit group and a printing press for performing the method are also provided.

  • Patent number: 6836283
    Abstract: The method is for setting the line width of recorded image lines of a focused image beam in an exposer. The exposure point has a diameter and an area with a non-uniformly distributed power density. The recording material has a first exposure threshold and is exposed with an energy density near a second exposure threshold that is substantially higher than the first exposure threshold. The recording material can be a photopolymer printing plate. The line width of the recorded image lines is determined from the distribution of the power density over the area of the exposure point by integrating the time variation of the power density resulting from the exposure speed of the laser beam. The line width is set, by changing the diameter of the exposure point and/or by the laser power, such that the line width is substantially equal to the line spacing.

  • Patent number: 6834441
    Abstract: A shirt-smoothing device includes a lower part and an inflatable body fixed thereon. Because the inflatable body must be at least the same size as the shirt to be smoothed, the device has considerable height, however, the rigid components in the area of the inflatable body are lowerable to handle the device more easily and, more particularly, to stow it away easily. An internally disposed supporting frame and a button strip tensioner disposed in front of the inflatable body can be lowered after use into the lower part, whereby the inflatable body, which is exclusively connected to the supporting frame at the top becomes folded. The same applies to flexible inflatable support bodied and support nets disposed between the inflatable body and the supporting frame. The storage space required for the shirt smoothing device can be substantially reduced by the invention and the handling and storage thereof simplified.

  • Patent number: 6835666
    Abstract: A mask is fabricated by applying a sacrificial layer on a semiconductor wafer. The sacrificial layer is then processed with the aid of a first and a second lithographic process sequence in order to pattern the sacrificial layer in a first and a second direction. A hard mask layer is subsequently applied in order to completely enclose the patterned sacrificial layer. Finally, the sacrificial layer is then removed from the hard mask layer.

  • Patent number: 6833067
    Abstract: A drain device for draining flat roofs, balconies, terraces or other flat structures, has an inflow body provided with a collar rim. When the inflow body is mounted, the collar rim lies on the surface of the roof. A loose flange can be introduced into the inflow body. The flange also has a collar rim. A connector film can be tensed between the collar rims of the inflow body and the loose flange for establishing a tight connection of a covering layer between said two elements. In order to allow for abnormally large amounts of water to be drained, the inflow body is provided with a cavity, into which two drain pipes and lead. One of the drain pipes co-operates with a pressurized, i.e., a pumped drainage system, and the other one of the drain pipes cooperates with a free-flowing drainage system.
