A search engine system assists users in locating web pages from which user-specified products can be purchased. Web pages located by a crawler program are scored, based on a set of criteria, according to likelihood of including a product offering. A query server accesses an index of the scored web pages to locate pages that are both responsive to a user's search query and likely to include a product offering. In one embodiment, the responsive web pages are listed on a composite search results page together with responsive products included in a product catalog.

In one embodiment of the invention, a robotic surgical instrument is provided for the control of flows of one or more fluids into and out of a surgical site. The robotic surgical instrument may include a housing, a flow control system, a hollow tube, and one or more hose fittings. The housing to couple the instrument to a robotic arm. The flow control system mounted in the housing includes one or more controlled valves to control the flow of one or more fluids. The hollow tube has a first end mounted in the housing coupled to the flow control system. A second end of the hollow tube has one or more openings to allow the flow of fluids into and out of the surgical site. The hose fittings have a first end coupled to the flow control system and a second end to couple to hoses.

In one embodiment of the invention, a robotic surgical system is provided including a master control console and a surgical manipulator. The master control console generates control signals to cause one or more fluids to flow into or out of a surgical site. The surgical manipulator is coupled to the console to receive the control signals and includes at least one robotic arm and a surgical instrument coupled thereto. The surgical manipulator controls the surgical instrument in response to the control signals to control the flow of the one or more fluids into or out of the surgical site. The surgical instrument has a first robotically controlled valve that is responsive to the surgical manipulator and a hollow tube having a first end coupled to the first robotically controlled valve with an opening at a second end to direct the flow of one or more fluids.

A valve assembly has a valve housing, an inlet, an outlet and a flow passage extending between the inlet and the outlet. A shut-off valve is mounted on the housing adjacent the inlet and a flow control valve is mounted on the housing adjacent the outlet. By mounting both valves on the same housing, the dimensions of the assembly are reduced.

An irrigation control device has a controller sealed within a watertight housing. The control device also has an antenna, power supply and battery charging device, such as a solar array. The controller receives signals through the antenna and updates one or more watering schedules stored in a memory module, based on the received signals, and generates control signals to execute a watering schedule. The battery charging device recharges the power supply and the irrigation control device requires no external electrical connections for power or control. Control signals are generated in a central controller remote from the rotor, and are preferably transmitted to the rotor antenna through a commercial paging or other type of public broadcast network.

An apparatus, program product and method propagate errors detected in an IO fabric element from an IO fabric that is used to couple a plurality of endpoint IO resources to processing elements in a computer. In particular, such errors are propagated to the endpoint IO resources affected by the IO fabric element in connection with recovering from the errors in the IO fabric element. By doing so, a device driver or other program code used to access each affected IO resources may be permitted to asynchronously recover from the propagated error in its associated IO resource, and often without requiring the recovery from the error in the IO fabric element to wait for recovery to be completed for each of the affected IO resources. In addition, an IO fabric may be dynamically configured to support both recoverable and non-recoverable endpoint IO resources. In particular, IO fabric elements within an IO fabric may be dynamically configured to enable machine check signaling in such IO fabric elements in response to detection that an endpoint IO resource is non-recoverable in nature. The IO fabric elements that are dynamically configured as such are disposed within a hardware path that is defined between the non-recoverable resource and a processor that accesses the non-recoverable resource.

The invention relates to modified polymerase enzymes which exhibit improved incorporation of nucleotide analogues bearing substituents at the 3′ position of the sugar moiety that are larger in size than the naturally occurring 3′ hydroxyl group. Also described are methods of using the polymerases to incorporate nucleotides into polynucleotides, particularly in the context of DNA sequencing.

An information retrieval system includes a query revision architecture that integrates multiple different query revisers, each implementing one or more query revision strategies. A revision server receives a user's query, and interfaces with the various query revisers, each of which generates one or more potential revised queries. The revision server evaluates the potential revised queries, and selects one or more of them to provide to the user.

An information retrieval system includes a query revision architecture that integrates multiple different query revisers, each implementing one or more query revision strategies. A revision server receives a user's query, and interfaces with the various query revisers, each of which generates one or more potential revised queries. The revision server evaluates the potential revised queries, and selects one or more of them to provide to the user. A confidence estimator and method provide the ability to improve the likelihood of success of suggested revised queries derived from various revision strategies. This is accomplished by tracking user queries, query revision links, results associated with revised queries, and various features of the original query and revised queries. This data is then analyzed using a predictive model to generate a set of rules that can be used to estimate the likelihood of a revised query being a successful revision for a given query.
