A technique for monitoring the quality of objects is disclosed. A container includes a multiple sensors and is configured to receive an object. The sensors monitor various metrics associated with the quality of the object, and a display is affixed to the container for displaying a visual indication of the quality of the object. The visual indication is based on data collected from the sensors. A quality monitoring module is executed by a processor to control the sensors to switch operation between a first mode of operation and a second mode of operation based on a detected change in one of the metrics monitored by the sensors.

An apparatus includes a housing defining a chamber and including a panel including an aperture, a sensor fixed inside the chamber and having a field of view through a lens and the aperture, and an annular disc attached to the sensor concentrically around the lens and including a radially outer edge contactlessly exposed to the chamber. An annular slot is defined by the disc. The slot extends at least 180 around the lens.

Selecting the information displayed on a sports watch, the watch comprising an interface for receiving movement information from at least one sensor; a display; and at least two display modes, wherein at least one mode is a sport mode configured to display sport-specific data. The method according to the invention comprises detecting a sport event based on the movement information received from the at least one sensor; and selecting the sport mode according to the detected sport event.

An arrangement and method are disclosed for inserting and removing a head of a measuring device to and from a process space. The arrangement includes a measuring device with a measuring head and a retractor tool connected to a valve member. The retractor tool includes rails, a cradle for receiving the measuring device and arranged to slide along the rails, and a driving mechanism for moving the cradle. A valve lock mechanism prevents opening of the valve member if the measuring device is not at a location barring a fluid flow from the process space, and the head of the measuring device is insertable to the process space when the measuring device is received in the cradle.
