Abstract: BYPASS CONTROL SYSTEM TO MAINTAIN A CONSTANT          AIR SUPPLY PRESSURE IN A HVAC DUCT SYSTEM                  ABSTRACT OF THE DISCLOSURE     A bypass control system and method monitors and controls the amount of air recirculated through a bypass duct from the air supply outlet supplied by a fan and motor from a single zone HVAC unit to the air intake thereof, a stepper motor driven bypass damper is located in the bypass duct having a damper blade movable between opened and closed positions and intermediate positions therebetween, and a bypass monitor is connected to the bypass damper for controlling the operation of the stepper motor of the bypass damper.  A first amperage sensor is looped around the common lead of the motor and the monitor provides information indicative of the amount of work performed by the motor to the monitor, the motor performing less work when static air build up occurs at the outlet due to closure of dampers in the duct system conditioning air to a plurality of zones, and the monitor causes the bypass damper to open to correspondingly compensate for the static air pressure build up by reducing same and causing more air to be recirculated through the bypass duct to maintain the air pressure supplied by the HVAC unit to the duct system generally constant.  When the motor is two speed, a second sensor   is looped around the high speed lead of the motor and provides information indicative of the speed to the monitor which analyzes same and the information from the first sensor before sending control signals to the bypass damper to modulate same toward opened or closed positions or positions therebetween.  The monitor includes means for establishing a communication link with a remote external source, and the monitor has indicating lights indicative of the status of the operating conditions of the bypass damper.  The monitor includes a microprocessor which receives information from the first and second sensors and analyzes same in conjunction with a data base before sending control signals to the bypass damper.

Abstract: CALIBRATED POWER DETECTOR                 Abstract of the Disclosure Power provided by an alternating signal having a frequency variable in a wide and relatively high range such as approximately ten megahertz (10 mHz) to forty gigahertz (40 gHz) is indicated by a detector.  For the purpose  of calibrating the detector, an alternating signal is introduced from a source to a bridge which includes a regulating member such as a thermistor.  The bridge also receives a direct voltage.  The thermistor is maintained at a particular impedance such as four hundred ohms (400), regardless of the power provided by the alternating signal, by varying the magnitude of the direct voltage.  The alternating signal, which is regulated in accordance with the dc voltage from the bridge, is also introduced to the detector.  The output of the detector is introduced to a data processing unit which processes the detector output to indicate the power provided by the alternating signal.  The output from the data processing unit is converted to an analog signal which is combined with the signal from the bridge to produce a resultant signal.  The amplitude of the resultant signal is compared with a reference signal to produce an error signal and this error signal is introduced to the source of the alternating signal to obtain adjustments in the output from the source in a direction to minimize the error.          In this way, the data processing unit provides an output alternating signal of regulated and variable amplitude.  The output from the detector is also used to calibrate the output from the source of alternating signal when different attenuators are introduced into the system to provide different ranges of attenuation.
