Abstract: A method for controlling an electric heater of a vehicular heating, ventilation, and air conditioning (HVAC) system includes turning on the electric heater; determining whether an ambient air temperature of a vehicle is higher than or equal to a threshold ambient air temperature, and a battery temperature is lower than or equal to a threshold battery temperature; determining whether battery efficiency is lower than or equal to threshold efficiency when the ambient air temperature of the vehicle is higher than or equal to the threshold ambient air temperature, and the battery temperature is lower than or equal to the threshold battery temperature; and turning off the electric heater when the battery efficiency is lower than or equal to the threshold efficiency, wherein the electric heater is configured to receive electric energy from the battery.

Abstract: A dynamic postural balance training system includes a base frame, a support frame which extends upwards from the base frame, a roll motion frame which is coupled to the upper portion of the support frame by a first shaft so as to be rotatable to the left or the right, and a pitch motion frame which is coupled to the roll motion frame by a second shaft so as to be rotatable forwards or rearwards. The system also includes a pelvis fastening unit which is disposed inside the pitch motion frame and which expands to fix the pelvis of the user in place, a connector which extends downwards from the pitch motion frame, and a foot fastening unit which is coupled to the lower end of the connector and expands to fix the feet of the user in place.
