    Abstract: The invention provides a device and a method for extending the bandwidth of short wavelength and long wavelength fiber optic lengths. The invention provides for an optical transmitter package device comprising: a laser diode; and a semiconductor optical amplifier connected directly after and in close proximity to the laser diode, wherein the semiconductor optical amplifier is adapted to operate in a frequency domain such that the semiconductor optical amplifier filters and reshapes optical wavelengths from the laser diode, and wherein the semiconductor optical amplifier is biased below an amplification threshold for the semiconductor optical amplifier. The device may also comprises a feedback circuit which comprises an optical splitter, wherein the feedback circuit samples reshaped optical output from the semiconductor optical amplifier and dynamically adjusts one or both of the semiconductor optical amplifier and the laser diode. In the case of a multimode fiber, the present invention provides the additional ability to provide a controlled offset launch into the fiber and the ability to control modal noise devoid of a specialized optical connector.

    Abstract: A method and system for forming a virtual network. The method comprises the steps of providing each of a plurality of mobile objects (102, 105) with a transceiver (104), and transmitting a cellular/radio signals from a source (101). At least a first (105) of the mobile objects is located in an area (100) where the transceiver (104) of the first mobile object (105) does not receive the signal directly from the source (101), while a second (102) of the mobile objects is in a position where the transceiver (104) of the second mobile object (102) receives the signal directly from the source (101). The transceiver (104) of the second mobile object (102) is used to receive the signal directly from the source (101) and to transmit the signal to the transceiver (104) of the first mobile object (105).

    Abstract: A computer implemented method, data processing system, and computer usable program code are provided for maintaining computer network. Resources (518A,518B,518C) and services (520A,520B,520C) affected by a change to a resource (518A,518B,518C) are identified in response to receiving a request for the change (506). A determination of an optimal time for the change is made (512) based on a policy (514) associated with the service (520A,520B,520C). The change is deployed with a deployment engine (516).

    Abstract: A wearable data network is disclosed. The wearable data network includes a universal data warehouse (UDW) (105) and at least one purpose optimized device (POD) (110). The UDW (105) is carried out by the user and is, essentially, a personal data warehouse to store data having a variety of different types and uses (e.g., personal financial data, audio and video files, and presentation files). The UDW (105), however, is incapable of processing the user's data. Instead, one POD (110) is used in conjunction with one or more UDWs (105) to process the user's data. As is suggested by its name, a POD (110) is a device that has been optimized to carry out a specific purpose. One example, is a POD (110) that is designed to play the user's audio files, another example is a POD (110) that is designed to render the user's video files, and yet another example is a POD (115) that is designed to render the user's presentation files.

    Abstract: A method of manufacturing complementary metal oxide semiconductor transistors forms different types of transistors such as N-type metal oxide semiconductor (NMOS) transistors and P-type metal oxide semiconductor (PMOS) transistors (first and second type transistors) on a substrate (12). The method forms an optional oxide layer (52) on the NMOS transistors and the PMOS transistors and then covers the NMOS transistors and the PMOS transistors with a hard material (50) such as a silicon nitride layer. Following this, the method patterns portions of the hard material layer (50), such that the hard material layer remains only over the NMOS transistors. Next, the method heats (178, 204) the NMOS transistors and then removes the remaining portions of the hard material layer (50). By creating compressive stress in the gates (22) and tensile stress (70) in the channel regions of the NMOS transistors (NFETs), without creating stress in the gates (20) or channel regions of the PMOS transistors (PFETs), the method improves performance of the NFETs without degrading performance of the PFETs.
