QuantityKind
type: Class
comment: A QuantityKind is an abstract classifier that represents the concept of kind of quantity that is defined as aspect common to mutually comparable quantities. A QuantityKind represents the essence of a quantity without any numerical value or unit. Quantities of the same kind within a given system of quantities have the same quantity dimension. However, quantities of the same dimension are not necessarily of the same kind.

The O&M ontology (ISO 19156) defines Time Series Observation as an “observation whose result is a time-series”, while both Hl7 aECG and DICOM standards define the Series element as a sequence of data sharing a common frame of reference. In SAREF4health we termed this concept as Time Series Measurements since this sequence of data refers to time series measured by a device. Notice that in this term we avoided prefixing with ECG because this concept can be applied to other types of data.

We propose here a list of some units of measure that are relevant for the purpose of the Smart Appliances ontology, but this list can be extended.

Rechargeable Lithium Polymer battery
type: Power
comment: Like many personal electronic devices, Shimmer is powered by a rechargeable Lithium Polymer battery. The Shimmer battery is 3.7V, 450 mAh and contains a safety circuit board with over-current protection, which can trigger if a component short is created by a faulty peripheral or if components are bridged while the enclosure is open. The battery will return to normal operating condition after the short is removed and the unit is placed back in a Dock. The Shimmer operating life when using these batteries depends on a number of factors including which, if any, radio is in use, which sensors are enabled and the rate at which data is being sampled and transferred. Battery life estimation information for a number of different configurations is provided in section 6.2.3 and also contains further details on voltage measurement. Some Shimmer applications feature a low-battery message using an LED indicator (located near the reset button). There is also hardware low-battery protection which will prevent damage to the battery or Shimmer device. If your application fails to start or terminates abruptly after initiating streaming data over a radio or writing to flash, it could be a symptom of a battery in need of recharging. For details on battery re-charging please refer to Section 3.2.3 of this User Manual. If you suspect a fault with your Shimmer battery, please refer to the troubleshooting section of this manual.
