  • Patent number: 6169624
    Abstract: Micromachined grating modulators which exhibit achromatic behavior are described. One embodiment includes narrow and wide ribbons suspended above a substrate and alternatingly interleaved with each other. Narrow and wide reflective surfaces are formed on the narrow and wide ribbons. Compensating reflective surfaces are formed in the gaps between and beneath the ribbons. The width of the ribbons as well as the width of the gaps and the compensating reflecting surfaces are designed so that incident optical beam can be modulated or attenuated in an achromatic fashion.

  • Patent number: 6166608
    Abstract: The present invention is a stabilized oscillator system comprising an oven controlled crystal oscillator positioned inside an insulated housing. Within the insulated housing, there is a cold plate in thermal contact with the oven controlled crystal oscillator and a thermo-electric cooler in contact with the cold plate. A heat sink external to the insulated housing is in thermal contact with the thermo-electric cooler. The thermo-electric cooler pumps heat into or out of the oven controlled crystal oscillator through the cold plate and into or out of the heat sink. The thermo-electric cooler is controlled as part of a feedback loop which attempts to stabilize the output frequency of the oven controlled crystal oscillator.

  • Patent number: 6161103
    Abstract: A method for automatically defining aggregates for use in a datamart is described. The datamart includes fact and dimension tables. The method comprises accessing a schema description and an aggregates description for the datamart. The schema description specifies a schema, which in turn, defines the relationships between the fact tables and dimension tables of the datamart. The aggregates description specifies the aggregates, which define, from the schema definition, which aggregate tables are to be created from the fact tables and dimension tables in the datamart. The data in the aggregates correspond to the pre-computed results of specific types of queries. In response to a query, the aggregates can be searched to determine an appropriate aggregate to use in response to that query. The schema description is used to create a first set of commands to create and populate the fact and dimension tables.

  • Patent number: 6157959
    Abstract: A method and apparatus for providing kernel mode support for fast IPC between a client process and a server process. A client application accesses a kernel mode of an operating system via a device driver or similar method. The client creates an abstract "resource" data type and derives a client port therefrom. The client port references a call structure containing object call data. The call is transported via a transport agent to the server. The server accesses the kernel mode of the operating system and creates a resource data type and a server port derived from the resource type. The server awaits calls from the clients using the server port. When a call arrives, the server port extracts the data from the call structure and performs the requested service. The server port then transmits a response back to the client. The use of the abstract resource data type permits portability across different operating systems and platforms.

  • Patent number: 6151213
    Abstract: A platform for holding a plurality of modules or printed circuit boards wherein the platform or chassis contains shutters placed over airflow openings in the platform. The shutters are normally closed and are opened by the act of inserting a module into the platform. The shutters are in the closed position in all slots not occupied by a module and are in the open state in all slots populated by a module. The shutters open as the module is inserted and close when the module is removed. The closed shutters prevent airflow from passing through the unpopulated slots and empty space within the platform, thus forcing the airflow to pass through the space in which the modules are present. The platform also comprises a means of controlling the number of fans that are operational in accordance with the number of modules installed in the platform. The fans closest to the modules inserted into the platform are operational while fans close to unpopulated slots are turned off.

  • Patent number: 6149786
    Abstract: A modified universal exhaust gas oxygen sensor, referred to herein as a CEGA sensor, is provided which can be used to measure the concentration of a variety of components of a gaseous fuel emission including CO, CO.sub.2, O.sub.2, H.sub.2, and H.sub.2 O. The CEGA sensor employs at least one additional electrode on a ceramic substrate which possess a different catalytic activity relative to the electrodes that normally found on a UEGO sensor. The ceramic substrate may be made of any suitable ceramic and is preferably made of zirconia. The difference in catalytic activity between the additional electrode(s) and the electrodes native to the UEGO sensor create an oxygen gradient which enables a measure of combustion completeness to be calculated. In combination with an air/fuel ratio measured by the sensor, the concentrations of different components in the emission can be calculated.

  • Patent number: 6147987
    Abstract: The present invention provides a modular architecture for connecting a plurality of telephone lines to a computer network. The invention binds a plurality of network access servers together so that they form a single system image to clients dialing into the plurality of network access servers. The invention operates by providing a tunneling mechanism for communication between the network access servers. The tunneling mechanism facilitates packet re-forwarding so that a call dialed into a physical port in a network access server can be re-forwarded through a logical port in another network access server. This allows a call to be routed through a physical port in a network access server even if no logical port is available in the network access server. Packet re-forwarding also allows multilink connections through physical ports in multiple network access servers to be routed through a single logical port in a network access server.

  • Patent number: 6147971
    Abstract: Two solutions are provided for optimizing the algorithm used by the local node in calculating the route to a destination node. A first method optimizes the route calculation by associating a port/link information with the PTSEs received by the node. The association is made using the first PTSE to arrive from an originating node. The routing algorithm is then steered to begin routing to a destination using the associated port/link. A second method optimizes the route calculation by utilizing a special PTSE termed a ROUTE.sub.-- PTSE into which is placed the route the PTSE takes upon being flooded from the creating node to the local node. When routing, the local node traverses the DTL already existing in the ROUTE.sub.-- PTSE received from a particular originating node that is the current destination node.
