Abstract: The system uses a multi-position counter incorporated in the card in which a random number is entered when the card is issued. This number is entered in a central verification store together with the corresponding card number. Each time the card is used the counter is adjusted by the corresponding value and the vertification store is supplied with the new count value the verification number, the date and the utilised value for each communication. The incoming data is arranged in time sequence at the verification store. Each new count value is compared with the preceding count value.

Abstract: Reflection of incident optical radiation (18) from a highly reflective metal layer (12), such as aluminum or titanium, into a photoresist layer (14) is reduced by interposing a layer of titanium nitride (16) between the metal and photoresist layers. The thickness of the TiN layer depends on the wavelength of the optical radiation used to expose the photoresist and on the optical properties of the underlying metal layer. Reflectance of less than about 2% may be achieved using the TiN layer in conjunction with aluminum and less than about 5% in conjunction with titanium, in accordance with the invention. If left in place after patterning an underlying aluminum layer, the TiN layer also serves to suppress hillock formation in the aluminum layer.

Abstract: The invention relates to a network, especially an Ethernet, Fast Ethernet, or Gigabit Ethernet network, comprising redundancy features. At least two rows constructed of a number of network nodes (100 ... 107; 110 ... 117) are connected to one another via at least two communication channels of which only a first is active and the second is deactivated. The communication channels are realized by connecting ports of the network nodes. A network node of the second communication channel monitors the first communication channel for the possibility of interruption and places the second communication channel into the active state in the instance that the first communication channel is interrupted. As a result,  the provision of additional coupling devices between the rows is rendered unnecessary.
