Abstract: A system and method for providing communication between two computer bus segments. Two half-bridge circuits are connected to respective computer bus segments and frame data for a high speed transfer of the data between the half-bridge circuits. A common application is to connect multiple PCI segments that are individually limited to the number of components connected thereto. Connection through the high speed half-bridge circuits allows additional PCI components to communicate on a second computer bus segment, acting as an expansion bus.

Abstract: In the process for irradiation of solid materials with ions, primarily to change their surface structure, and composition respectively, the ion irradiation is carried out by means of repetitive impulses. The apparatus carrying out the process has a charging unit (26) consisting of current generators, a control unit (27) connected to the charging unit, the voltage limiter (28), the spark power supply (25) and to the implantation control unit (29). The implantation control unit (29) receives and evaluates incoming signals form target unit (211) and controls the control unit (27) via lead n. The current generators of the charging unit (26) make switching off from the electric means unnecessary and they start recharging the impulse exciter (22) and the source magnet energy bank (23) immediately after the impulse is given.
