Abstract: A progressive stopper for a pressure sensing element is able to redistribute and reduce the stress of a diaphragm exposed to high pressure via multi-step contacts, such as at least dual contacts, where the diaphragm (designed for detecting pressure within a defined pressure range) is enabled to withstand much higher pressures above of the defined pressure range, such that the progressive stopper prevents catastrophic failure of the diaphragm. The progressive stopper is created to redistribute and reduce stress on the diaphragm significantly and effectively. The progressive stopper does not limit the output of the pressure sensing element such that the pressure sensing element is able to maintain the output voltage above the maximum output voltage of the defined pressure range when the diaphragm is exposed to high pressures with reduced stresses and strains.

Abstract: Graphical user interfaces (GUIs) for reviewing and evaluating geospatial data are provided. A GUI may allow a user to configure a geospatial data quality assessment system by grouping feature classes into one or more categories and selecting target quality scores for the overall data set and/or one or more categories. A GUI may display one or more review areas for a user to review and allow a user to generate one or more error calls in the review areas. A GUI may display one or more scores associated with a geospatial data set. A GUI may allow a user to modify to which category one or more feature classes are assigned. In response to an adjustment of one or more feature classes between categories, the user interfaces may display one or more updated quality scores associated with one or more categories.

Abstract: Methods and systems for evaluating the quality of a geospatial data set are provided. Regions of a data set may be selected for review based on statistical methods and a distribution of map features in the data set. Based on errors identified in the selected regions, one or more quality scores may be generated for the data set. Quality scores may be applied toward assessing the utility of the data set against an intended use. Quality scores may be modified in response to an indication that certain feature classes are not relevant for an intended use of the data set. Information associated with the review of a data set may be tracked and stored.

Abstract: The present invention provides a subsurface instrument and a system for the collection and transmission of deep ocean data utilizing standard buoy mooring lines. The system includes a moored surface buoy and a submerged data collection instrument both inductively coupled to the buoy cable. The instrument has a transducer responsive to the characteristics of seawater. A slave modem is interconnected to the transducer through an A/D converter allowing analog transducer signals to be converted to standard telephone modem signals. The modem signals are inductively coupled into the mooring cable and received by a master modem located in the buoy. The buoy may contain a satellite transceiver allowing transmission of the signals to a remote location. The subsurface instrument is battery powered and battery life is extended by powering down when the instrument is not in use.
