Abstract: A control device configured to control a power to be supplied to a heater unit. The control device cuts off the power to be supplied to a heating portion when it is determined that an event where a maximum temperature that the processing liquid within the heater unit reaches exceeds a processing liquid upper limit temperature is likely to occur even when a supply of the power to the heating portion is stopped based on an actual temperature of the processing liquid measured by a temperature detector under an assumption that a flow of the processing liquid flowing in a processing liquid supply line is stopped.

Abstract: The present invention reuses an accelerometer, or, more precise, sensed accelerations of a body sensor for user control of the body sensor. This is achieved by detecting predefined patterns in the acceleration signals that are unrelated to other movements of the patient. These include tapping on/with the sensor, shaking, and turning the sensor. New procedures are described that make it possible to re-use the acceleration sensing for reliable gesture detection without introducing many false positives due to non-gesture movements like respiration, heart beat, walking, etc.
