An intraoral scanner including an improved power management unit

An intraoral scanner comprising:

• a projector unit configured to emit light at least onto a dental object of a patient;
• an image sensor configured to acquire reflected light from at least the dental object;
• a battery for powering the intraoral scanner;
• a processor unit configured to process the reflected light into one or more 2D images and/or 3D images;
• a wireless interface configured to communicate with an external device the one or more 2D images and/or 3D images,
• a motion sensor configured to sense a motion of the intraoral scanner;
• a timer unit;
• a temperature sensor configured to produce a temperature signal that includes a temperature of the intraroral scanner, and
• a power management unit configured to reduce the power consumption of the intraoral scanner based on a motion signal provided by the motion sensor, a timer signal provided by the timer unit, and the temperature signal, a and wherein the motion signal includes information about motion of the intraoral scanner, wherein the motion is below a motion threshold during one or more time periods, and after each of the one or more time periods the power consumption is reduced gradually, and, the power consumption is reduced when the temperature of the intraoral scanner is above a temperature threshold.
