Introduction smart-knife

This part of the ontology defines 11 classes and 5 properties .

Module Term Name Type Definition
smart-knife AccelerationMeasurementCapability class This class describes measurement capabilities for accelerometer sensors. The property ssn:forProperty is restricted to ucum:acceleration.
smart-knife AccelerationObservation class A class describing acceleration observations. Properties ssn:observationResult, ssn:observedBy, and ssn:observedProperty are restricted accordingly.
smart-knife AccelerationSensorOutput class A class describing sensor output for acceleration measurements. Properties ssn:hasValue and ssn:isProducedBy are restricted accordingly.
smart-knife AccelerationValue class Acceleration value measured in g - standard acceleration of free fall.
smart-knife Accelerometer class Accelerometer is a subclass of sensing devices which measures acceleration. The individual describing a phisical quality "acceleration" is defined in the imported MobileWeb ontology of measurement units. To align the MobileWeb ontology with the SSN ontology, the class muo:PhysicalQuality from the MobileWeb ontology is defined as a subclass of the class ssn:Property.
smart-knife FrequencyValue class Frequency value measured in Hz.
smart-knife QuantityObservationValue class Because SSN ontology does not specify the format of ssn:ObservationValue, in this example we define our own class representing quantities. It is characterised by the value () and the measurement unit.
smart-knife WiTilt30AccelerationMeasurementCapability class This class describes measurement capabilities of WiTilt 3.0 acceleration sensors. Measurement capabilities are characterised by two parameters: measurement range and frequency. Possible values of these parameters are described by classes WiTilt30MeasurementRange and WiTilt30MeasurementFrequency respectively. A specific instance of a WiTilt 3.0 sensor must have exactly one value for each of these parameters.
smart-knife WiTilt30Accelerometer class This class describes WiTilt v3.0 accelerometers. All possible configurations of their measurement capabilities are defined using the class WiTilt30AccelerationMeasurementCapability, so the property ssn:hasMeasurementCapability is restricted to instances of this class.
smart-knife WiTilt30MeasurementFrequency class This class describes maximal output frequency values of WiTilt 3.0 accelerometers in four modes: degree mode (50Hz), gravity mode (135Hz), raw ADC mode (220Hz), and binary mode (610Hz). Because the SSN ontology does not specify how the values of measurement properties should be expressed, three properties are introduced: hasMeasurementPropertyValue (for exact values), hasMeasurementPropertyMaxValue (for maximal values), and hasMeasurementPropertyMinValue (for minimal values).
smart-knife WiTilt30MeasurementRange class This class defines possible measurement ranges of a WiTilt 3.0 accelerometer sensor. These sensors can be calibrated to measure acceleration in the ranges of +/-1.5g, +/-2g, +/-4g and +/-6g. These four ranges are expressed using instances of this class: WiTilt30MeasurementRange_1...WiTilt30MeasurementRange_4. Because the SSN ontology does not specify how the values of measurement properties should be expressed, three properties are introduced: hasMeasurementPropertyValue (for exact values), hasMeasurementPropertyMaxValue (for maximal values), and hasMeasurementPropertyMinValue (for minimal values).

WiTilt30MeasurementFrequency

This class describes maximal output frequency values of WiTilt 3.0 accelerometers in four modes: degree mode (50Hz), gravity mode (135Hz), raw ADC mode (220Hz), and binary mode (610Hz). Because the SSN ontology does not specify how the values of measurement properties should be expressed, three properties are introduced: hasMeasurementPropertyValue (for exact values), hasMeasurementPropertyMaxValue (for maximal values), and hasMeasurementPropertyMinValue (for minimal values).

WiTilt30MeasurementRange

This class defines possible measurement ranges of a WiTilt 3.0 accelerometer sensor. These sensors can be calibrated to measure acceleration in the ranges of +/-1.5g, +/-2g, +/-4g and +/-6g. These four ranges are expressed using instances of this class: WiTilt30MeasurementRange_1...WiTilt30MeasurementRange_4. Because the SSN ontology does not specify how the values of measurement properties should be expressed, three properties are introduced: hasMeasurementPropertyValue (for exact values), hasMeasurementPropertyMaxValue (for maximal values), and hasMeasurementPropertyMinValue (for minimal values).
