  • Patent number: 6832236
    Abstract: A script is created which accurately monitors filesystem usage. Initially, a filesystem is identified to be monitored. Growth parameters for the particular filesystem are stipulated which, if exceeded, will result in notification to an administrator of the system. Thresholds are set for the selected growth parameters. Script execution timing is set, and the script is automatically executed at the preset time intervals. Each time the script executes, a comparison is made between the system specifics and preset growth thresholds. If a filesystem exceeds a threshold, then notification is provided to the system administrator.

  • Patent number: 6820161
    Abstract: A method, system, and apparatus for providing data to an I/O adapter from a PCI-to-PCI bus bridge is provided. In one embodiment, once the PCI-to-PCI bus bridge receives a request for data from the I/O adapter, the PCI-to-PCI bus bridge determines whether the requested data is contained within a cached memory within the PCI-to-PCI bus bridge. If the data is contained within the cached memory, then the requested data is provided to the I/O adapter from the cached memory. If the requested data is not within the cached memory, the data is fetched from system memory, then cached in the PCI-to-PCI bus bridge, and sent to the requesting I/O adapter. To ensure that the data in the cached memory within the PCI-to-PCI bridge is not stale, signals are received, periodically or aperiodically, by the PCI-to-PCI bridge from a PCI host bridge indicating whether the data contained within the buffers is stale.

  • Patent number: 6816882
    Abstract: A user contracts with an application service provider for hosting a needed application. By contracting with a service provider the user may interact with the application by using only a thin client rather than maintaining a thick client. The user rents an application from either the service provider or an independent application provider. If the user procures the application from an application provider, the application provider negotiates hosting terms with the service provider prior to installing the application into the service provider's warehouse. The application provider also checks that the services provided by the service provider meet the minimum requirements of the application. Once installed, the service provider may offer the application to other users along with services for the application. The user may procure additional services from the service provider for supporting the application. A user can then dynamically download the application “on-demand”.

  • Patent number: 6810067
    Abstract: A laser source is provided by the present invention, comprising a laser diode and has an active region with asymmetric distributed Bragg reflectors (DBRs) at either end to reflect light within the cavity, and an outcoupling grating in the center of the device, which couples light out of the cavity. One DBR is long and shallow, with a narrow-band reflective spectrum. The other DBR is short and deep, with a wide-band reflective spectrum. The lasing wavelength is determined by the reflective spectrum overlap of the two DBRs. Since the shallow DBR is highly reflective to only one Fabry Perot wavelength, and the deep DBR is highly reflective to a wide band of Fabry-Perot wavelengths, it is the reflective spectrum of the shallow DBR that determines the lasing wavelength.

  • Patent number: 6795963
    Abstract: This system sets up a framework that allows for separating debug information from executable code. The system is comprised of a compiler, a linker and a debugger. The compiler produces optimized object code and a debugging information file that contains information necessary for symbolic debugging. The linker merges the optimized object files to produce an optimized executable file as well as debugging information files to produce a composite debugging information file. This debugging information file can be further refined when the program is executed to include runtime dependencies. The debugger provides a source code debugging environment and a core dump debugging environment for the optimized code. The debugger allows monitoring of variable values, placement of watches on changes in variable values, setting breakpoints by location or by name and performing program debugging at a source code level.

  • Patent number: 6775427
    Abstract: A system capable of creating multiple beams of light using laterally coupled waveguides. Each beam is of a different central wavelength, capable of being generated on chip and coupled into a single fiber, and emitted from a single outcoupling grating (OCG). The present innovations can be used to create a multiple wavelength source generating multiple signals of different wavelengths simultaneously. The present innovations can also function as a tunable laser source system, capable of generating one of many different wavelength signals at a time. Waveguides are laterally coupled through, for example, evanescent coupling. The degree of coupling is controlled by varying the voltage applied to contacts attached to the waveguides at the coupling region.

  • Patent number: 6714575
    Abstract: A modulation technique for optical signals. A laser diode having an outcoupling grating in the waveguide between two reflectors is provided. A second waveguide is positioned next to the first waveguide. The first end of the second waveguide is optically connected to the first waveguide on one side of the outcoupling grating, while the second end of the second waveguide is optically connected to the first waveguide on the other side of the outcoupling grating. Switches are provided that control the amount of light coupled between the waveguides. For example, when the switches are in a first state, no light is coupled between the two waveguides, and all the light stays in the laser diode or is coupled out of the outcoupling grating, while none of the light couples into the second grating; and when the switches are in a second state, some or all of the light from the first waveguide is coupled into the second waveguide. By toggling the states of the switches, the light emitted from the laser diode is modulated.
