Abstract: The present invention provides an apparatus for mapping pipeline for use in a fluid pipeline, comprising: a pressure gauge that measures the pressure of the fluid in the fluid pipeline; a gyroscope that measures the angular velocity of the apparatus for mapping pipeline in the fluid pipeline; a processing module that collects and converts the pressure of the fluid and the angular velocity to a pressure data and an angular velocity data, respectively; and a data output module that outputs the pressure data and the angular velocity data. The present invention also provides a method for mapping pipeline and a system using the same that obtain the spatial layout of the fluid pipeline by analyzing the pressure data and the angular velocity data.

Abstract: A heating system includes first and second heating devices, a temperature sensor, a first controller and a second controller. The first and second heating devices are respectively arranged above a crucible and around the crucible for heating semiconductor material in the crucible. The temperature sensor is configured to detect the temperature of the first heating device and to generate a temperature signal. The first controller is configured to control operation of the first heating device so as to adjust the temperature thereof based on the temperature signal. The second controller is coupled to the second heating device and is configured to control operation of the second heating device so as to adjust the temperature thereof, based on an external control signal.
