    摘要: A fan powered by a controlled external energy source and a flow measurement device measure the airflow exiting or entering grilles/registers of an HVAC system without impeding the airflow being measured. A flow straightening element is preferably employed to overcome any effects of a non-uniform or swirled airflow profile on the fan. Preferably, the RPM of the fan is measured to determine the airflow. The RPM/flow calibration of the fan is insensitive to pressure differentials or the fan is a pressure-sensitive fan submitted to appropriate pressure differentials. Alternatively, the voltage or current supplied to the external energy source is used to determine the airflow. Finally, the pressure differential across the flow straightening element can be measured to determine airflow, eliminating the impact of pressure differential across the flow measurement device and fan.

    摘要: The invention is of a novel business method for presenting pre-recorded promotional presentations to retail consumers at the point of sale. The system plays a short consumer message upon activation by the consumer and educates the consumer about some aspect of the product for sale. This novel business method is a way for marketers to make individualized contact with the consumer at the point of sale without the use of sales personnel.
