Abstract: A method performed in a processing unit for determining calibration data to be used when processing data from a sensor unit connected to the processing unit, the method including receiving, from the sensor unit, an identifier which identifies and is calculated based on calibration data stored in the sensor unit, checking if there is an identifier stored in the processing unit identical to the received identifier, where the identifier stored in the processing unit identifies and is calculated based on calibration data stored in the processing unit, if an identical identifier is stored in the processing unit, using the calibration data stored in the processing unit identified by the identical identifier when processing data from the sensor unit, if no identical identifier is stored in the processing unit, requesting the sensor unit to transmit calibration data, and using the requested calibration data when processing data from the sensor unit.

Abstract: A method, performed by a monitoring device, may include detecting a temperature change, greater than a temperature change threshold, from a previous temperature to a current temperature; retrieving a trend-based motor position setting for a focus motor from a trend statistics memory based on the current temperature; and selecting a starting motor position setting for the focus motor based on the retrieved trend-based motor position setting or a current motor position setting. The method may further include performing a just noticeable difference modification on the focus motor using the selected starting motor position setting, wherein the just noticeable difference corresponds to a change in a motor position setting that results in a perceivable change in a focus level of the monitoring device, and selecting a temperature adjusted motor position setting for the focus motor based on a result of the just noticeable difference modification.
