Abstract: An authentication device designed to be used with an electronic device including a capacitive touch screen and a receiver, wherein the authentication device includes a plurality of pins arranged on the same face of the authentication device, at least two pins consisting of a conductive material, the other pins consisting of an insulating material, means for detecting pressure exerted on at least one pin, and means for emitting an authentication signal to be received by the receiver when pressure is detected.

Abstract: A network comprises a plurality of switching nodes interconnected by communication links for transferring digital packets. At least one switching node in the network pre-establishes a bypass virtual circuit through the network to bypass an element of the network, such as a switching node or a communication link, in the network. The bypass virtual circuit defines a path to another switching node in the network. The first switching node uses the bypass virtual circuit so constructed in forwarding of a packet in the event of a failure or other malfunction of the element if the first switching node would otherwise transfer the packet over that element.

Abstract: A wideband band bus in a base station of a wireless communication system includes consecutively interconnected slots and may be automatically configured into one or more sections that perform application specific cell processing operations, without requiring hardware or software changes to the base station. A section of the wideband bus includes a group of the consecutively connected slots containing digital signal processing modules which implement a cell processing application. The modules included in the slots of a section and the interconnections among the slots provide for diversity reception, expandable cell capacity and cell operations in accordance with wireless communication protocol standards.
