Abstract:
A capacitive pressure sensor array is made of two conductive layers, wherein each conductive layer is formed with a plurality of elongated conductors disposed in a substantially parallel manner between an upper and a lower insulating sheet, wherein the upper and lower insulating sheets are bonded to each other between adjacent conductors.
Abstract:
A pressure sensor measures the surface pressure distribution of a body supported by a surface, for example a person lying on a mattress. In one approach, a pressure mapping system acquires a customer's pressure map using a reference mattress and presents this pressure data in the form of a pressure map. The pressure map measurement data is then analyzed to determine body characterizing parameters such as body mass index, contact area and average peak pressure. The pressure map measurements are then located on a mattress category grid that has been referenced and aligned to a large population sample of measurements taken with a reference mattress. Alternatively, the pressure map measurements are matched to a physical profile category within a database. Each category provides ranked mattress recommendations based on selection and ranking criteria derived from pressure map data obtained from a large sample of test subjects. In this way, a customer's pressure map can be translated to a recommendation of specific mattresses or mattress categories that are offered by a mattress retailer or manufacturer.
Abstract:
A method for modelling pressure exposure and/or the risk of pressure ulcer formation includes steps of using pressure sensors to derive pressure exposure or risk values and displaying the pressure exposure or risk values in a graphical manner to a user. Computer-implemented systems includes a pressure-sensing interface mat and components for implementing the steps of the methods.
Abstract:
A computer system for modelling and controlling a hydrocarbon reservoir through management of fluid flow at individual wells. The computer system has program instructions which operate a computer model which uses oilfield production data to provide a model of future production. The model comprises an optimal regression model which represents injector and producer wells whose fluid flow characteristics are highly correlated with the fluid flow characteristics of the well of interest; the application of parsimonious information criterion techniques to identify well pairs that statistically contribute information to the optimal regression model; and a statistical reservoir model comprising the product of the optimal regression model and a significance matrix. The system is also provided with control means, responsive to the output of the computer model in order to control wells in the hydrocarbon reservoir.
Abstract:
A method and system for measuring the distribution of pressure forces over a selected area includes a sensor having an array of pressure sensing capacitance nodes formed by intersecting rows and columns, where measured capacitance of a node is compared to a fixed value of reference capacitance placed on each row that can be measured as if it was another node.

Abstract:
A capacitance pressure mapping system includes a plurality of sensor cells created by the intersection of electrode columns and rows, and a solid elastomer dielectric separating the electrode columns and rows. The elastomer is at least one planar sheet having a surface comprising a pattern of projections. There may be two sheets having opposing patterns of projections. The opposing patterns may be interlocking or corresponding.

Abstract:
A computer system protection method monitors and evaluates per process network communications activity to determine whether the process has been compromised. In one embodiment, a network modeling scheme gathers data to build a model and then compares networking activities to the model as they occur. In an alternate embodiment, modeling is not required and the comparison is done of network data collected at one layer of a communication system to network-related data collected at another layer. As a result of a comparison and an indication of compromise, a given remedial action is taken.
Abstract:
A generic instrumentation framework comprises two primary systems: an instrumentation generation system, and a runtime system. The instrumentation generation system creates an instrumentation generator that is specific to the system or subsystem to be instrumented. Preferably, the instrumentation generator is created by an instrumentation generation engine, which receives as input a system descriptor. The system descriptor is a set of metadata that comprise an interface specification. The instrumentation generation engine reads the system descriptor, identifies the target system, and selects an appropriate instrumentation generator. Using the system descriptor, the instrumentation generator then creates an instrumentation “package” comprising the actual instrumentation code itself (an executable) together with an instrumentation descriptor, which describes a set of one or more instrumentation points in the target system. The target system is then available to be instrumented with the instrumentation code. At an appropriate time, such as system start up, a telemetry stream adapter of the runtime system loads in and initiates the instrumentation code. A telemetry stream reader of the runtime system reads telemetry stream data provided by the telemetry stream adapter. The telemetry is then made available to an analysis module, which also receives the instrumentation descriptor to facilitate a forensic analysis of the telemetry.
