  • Apparatus for determining the concentration of a conductive fluid present in a fluid filled borehole
    Patent number: 8849572
    Abstract: An apparatus for determining the concentration of a conductive fluid present in a fluid filled bore hole is described. Such apparatus are known as water hold-up meters and are frequently used in oil, gas and water filled bore holes. In bore hole applications, data bandwidth between a down hole device and the surface can be limited, while determining water hold-up based on down hole measurements can be data intensive. A technique is proposed for calculating the water hold up that requires less data to be transmitted between the down hole device and the surface.

  • Reconciling data
    Patent number: 8849835
    Abstract: Methods, systems, and apparatus, including computer program products, are described for reconciling data. In one implementation, a method includes generating co-occurrence scores indicating whether data in entries in a first source of data co-occur within documents in a plurality of documents with data in entries in a second source of data. The co-occurrence scores for a given entry in the first source of data are used to identify a plurality of candidate matching entries in the second source of data for the given entry. Data in fields in the given entry are compared to that of one or more of the candidate matching entries to produce field similarity scores. The field similarity scores and the co-occurrence scores are used to determine a match for the given entry among the plurality of candidate matching entries.

  • Target trailing with safe navigation with colregs for maritime autonomous surface vehicles
    Patent number: 8849483
    Abstract: Systems and methods for operating autonomous waterborne vessels in a safe manner. The systems include hardware for identifying the locations and motions of other vessels, as well as the locations of stationary objects that represent navigation hazards. By applying a computational method that uses a maritime navigation algorithm for avoiding hazards and obeying COLREGS using Velocity Obstacles to the data obtained, the autonomous vessel computes a safe and effective path to be followed in order to accomplish a desired navigational end result, while operating in a manner so as to avoid hazards and to maintain compliance with standard navigational procedures defined by international agreement. The systems and methods have been successfully demonstrated on water with radar and stereo cameras as the perception sensors, and integrated with a higher level planner for trailing a maneuvering target.

  • Enabling throttling on average write throughput for solid state storage devices
    Patent number: 8850153
    Abstract: A mechanism is provided for enabling throttling on average write throughput instead of peak write throughput for solid-state storage devices. The mechanism assures an average write throughput within a range but allows excursions of high throughput with periods of low throughput offsetting against those of heavy usage. The mechanism periodically determines average throughput and determines whether average throughput exceeds a high throughput threshold for a certain amount of time without being offset by periods of low throughput.
