  • Patent number: 7554508
    Abstract: A universal frequency translation module (UFT) frequency translates an electromagnetic (EM) input signal by sampling the EM input signal according to a periodic control signal (also called an aliasing signal). By controlling the relative sampling time, the UFT module implements a relative phase shift during frequency translation. In other words, a relative phase shift can be introduced in the output signal by sampling the input signal at one point in time relative to another point in time. As such, the UFT module can be configured as an integrated frequency translator and phase-shifter. This includes the UFT module as an integrated down-converter and phase shifter, and the UFT module as an integrated up-converter and phase shifter. Applications of universal frequency translation and phase shifting include phased array antennas that utilize integrated frequency translation and phase shifting technology to steer the one or more main beams of the phased array antenna.

  • Patent number: 7321735
    Abstract: A method and system for converting an optical signal to electrical information signals, including demodulated baseband information signals and modulated baseband signals at multiple harmonics. In an embodiment, the optical information signal is amplitude modulated with information. The method converts an optical signal to electrical charge, accumulates the electrical charge, and periodically transfers the accumulated electrical charge to a storage device, whereby the periodically transferred electrical charge forms the electrical signals. An exemplary system includes an optical transducer and a universal frequency translator coupled to an output of the optical transducer. The optical transducer receives an optical signal and converts the optical signal to electrical charge. The universal frequency translator periodically transfers energy from the electrical charge and forms the electrical signals from the transferred energy.

  • Patent number: 7027786
    Abstract: Coherent detection of a received EM signal using universal frequency translation (UFT) is described herein. The received EM signal is sampled according to a sub-harmonic LO signal, where the LO signal is in frequency and phase coherence with the received EM signal. The coherent receiver includes a down-converter/demodulator and a synthesizer/loop filter that are both implemented using UFT technology. The down-converter/demodulator samples the EM input signal using a UFT module according to the coherent sub-harmonic LO signal that is generated by the synthesizer/loop filter. The synthesizer/loop filter generates the coherent LO signal using a phase detector, a loop filter, and an up-converter. The phase detector and up-converter are implemented using UFT modules.

  • Patent number: 6336152
    Abstract: A system for configuring a network adapter of a computer without user intervention. Device information for the devices of the computer, including each network adapter, is collected to uniquely identify the devices and to describe the device characteristics associated with the operation of those devices with the computer. Computer resources, which support the functions of the devices within the computer, are allocated based upon this device information. This allocation process prevents a potential conflicting use of computer resources by the installed devices. A device driver, which enables communications between a corresponding device and the computer, is also identified and loaded for each of the devices in response to the allocation of computer resources. In response to loading the driver for each network adapter, each network configuration routine or layer for a particular interface of the corresponding network adapter is identified.

  • Patent number: 6279032
    Abstract: A method and system for selecting a set of systems (nodes) for a server cluster from at least two non-communicating sets of systems. A persistent storage device with cluster configuration information therein is provided as a quorum resource. Using an arbitration process, only one system exclusively reserves the quorum resource. The set with the system therein having the exclusive reservation of the quorum device is selected as the cluster. The arbitration process provides a challenge-defense protocol whereby a system can obtain the reservation of the quorum device when the system that has the reservation fails.

  • Patent number: 6178529
    Abstract: A method and system in a server cluster for monitoring and controlling a resource object, such as a physical device or application. A cluster service connects to a resource monitoring component to control and monitor the health of one or more resource objects. The resource component includes a plurality of methods, common to all such resource components, for calling by the resource monitor to control and monitor operation of the resource object therethrough. The common methods enable the cluster server to treat all resources similarly without regard to the type of resource.

  • Patent number: 5958256
    Abstract: A method for cleaning industrial wastewater comprising pretreatment of the wastewater stream by intercepting and removing settleable solids prior to subjecting the stream to primary cleaning systems are disclosed. The method of pretreatment comprises pumping wastewater from a collecting reservoir or sewer through a hydrocyclone to separate the stream into an overflow of reduced solids content and an underflow of enhanced solids content. The overflow is directed to a holding tank or forebay of the primary cleaning system. The primary cleaning system comprises a gravity settler, a CPI (corrugated plate interceptor) system or API (American Petroleum Institute) separator for example. The gravity settler is operated to obtain an effluent essentially free of settleable solids and a sludge stream. The underflow with its enhanced solids content is screened to obtain a screened water stream and a sludge of screened solids which is directed to a collection container.

  • Patent number: 5819107
    Abstract: A system for managing the assignment of device drivers to devices of a computer system. The computer system can maintain device-related information for a primary device and for devices that are "compatible" with the primary device. This device information supplies an indication of whether a device driver intended for primary use with a device is maintained by the computer system. Moreover, the device information provides an indication of whether one or more device drivers compatible with the primary device are maintained by the computer system. During assignment of device drivers to devices of the computer system, the device information is examined to determine whether the intended device driver for the primary device is available to support the operations of that device. If not, the device information is examined to determine whether a device driver for a device that is compatible with the primary device is available for supporting computer operations of the primary device.

  • Patent number: 5809329
    Abstract: A system for managing the configuration of devices of a computer system. Device information is obtained to uniquely identify each device and to describe the device characteristics associated with device operation. To obtain device information, a particular device is detected on a selected system bus and thereafter assigned an identification code that uniquely identifies the detected device. A system bus code, which uniquely identifies the selected system bus, is appended to the identification code, thereby forming a device identification code associated with the particular device. Logical configuration data, which supplies configuration requirements for device operation, is also obtained for the detected device. This data collection process is repeated until device information is obtained for each of the devices connected to the selected system bus. Resources are allocated to each device based on the device identification code and the logical configuration data.

  • Patent number: 5793979
    Abstract: A system for allocating resources for use by devices of a computer system. A possible configuration of elements of a resource is obtained. This possible configuration defines the resource elements that are appropriate for operating the devices within the computer system. For a selected device, a determination is made whether a particular resource element is available for use by this device. If not, another possible configuration is obtained and the process begins anew. In contrast, if the particular resource element is available, then this resource element is assigned for use by the selected device. This resource allocation process continues until resource elements have been assigned to the remaining devices.
