Abstract: A server may be bypassed in the context of retransmitting data packets, when such data packets are missing or lost due to interference or some other network error. Decreased throughput and other disadvantages associated with data packet retransmission are avoided by negating the need to transmit retransmission request packets to the server and retransmitting a missing/lost data packet from the server. Instead, retransmission request packets may be sent to a router, and the router may respond by directly retransmitting the missing/lost data packet to the client, where prior to retransmitting the missing/lost data packet, it is determined whether the data packet is a Transport Control Protocol or User Datagram Protocol packet, and proceeding with the retransmitting only if the data packets is a Transport Control Protocol packet.

Abstract: Disclosed herein is a method of forming a reliable high performance capacitor using an isotropic etching process to optimize the surface area of the lower electrodes while preventing an electrical bridge from forming between the lower electrodes. This method includes multiple sacrificial oxide layers that are formed over a substrate, an insulating layer with contact plugs, and an etch stopping layer. The sacrificial oxide layers are patterned and additionally isotropically etched to form an expanded capacitor hole. An exposed portion of the etch stopping layer is then etched to form a final capacitor hole exposing an upper portion of the contact plug and a portion of the insulating layer adjacent thereto. The semiconductor substrate having the final capacitor hole is cleaned to remove a native oxide film on the exposed upper portion of the contact plug.

Abstract: A PCMCIA type wireless modem comprises an interface module connected to the portable PC to receive a data packet. The interface module includes a single UART and attribute memory, interrupt signal generator connected to the interface module to receive a first interrupt signal and to output a second interrupt signal. The second interrupt signal is enabled after the complete data packet is received in the memory. The modem card includes a processor connected to the interface module and responsive to the second interrupt signal. When the second interrupt signal is enabled, the processor accesses the data packet from the memory. The interrupt signal generator comprises a counter responsive to the first interrupt signal, a register, a comparator to compare output values of the counter and the register, and a pulse generator to produce the second interrupt signal when the output of the counter matches a stored value of the register.
