An improved heating system air pressure sensing port. An example aircraft pitot tube heater uses Positive Temperature Coefficient (PTC) switching thermistors arranged to automatically sense the outside air temperature and heat to a design set point temperature. When a high outside air temperature is experienced, the pitot tube will not turn on. The pitot tube heater only turns on below the design set point and will consumes less current than the standard aircraft pitot tube heaters when operating at very cold temperatures. Virtually no current is drawn when the pitot tube increases past the set point, thus reducing the power drain on the aircraft system. The use of multiple thermistors gives the example pitot tube a level of failure redundancy that is not available in current pitot tube heaters.

The invention discloses a table tennis game serve recognition system and method based on a motion trail. The system includes a module for obtaining pressure sensing data and judging whether or not a table tennis bat hits a table tennis, a module for reading successive position data of the table tennis bat before the table tennis is hit by the table tennis bat, and a module for judging table tennisgame serve according to the motion trail. Table tennis position data is obtained by deploying an Internet of Things component (including a signal intensity positioning component and the like) for positioning the table tennis in a table tennis system. A pressure sensor deployed on the table tennis bat surface obtains the pressure sensing data. A server judges a serve moment according to the pressure sensing data, and generates the motion trail of the table tennis before the table tennis is hit according to the table tennis position data. Before the table tennis game serve is carried out, the table tennis motion trail must be in accordance with motion trail models of upcast and falling, and accordingly whether or not the motion of hitting the table tennis by the table tennis bat is the table tennis game serve is judged. The table tennis game serve recognition system and method based on motion trail resolve the problem that a table tennis motion system based on the Internet of Things fails to effectively recognize the table tennis game serve.
