Abstract: An air quality sensor system is disclosed comprising a housing defining a sidewall means. An air input is located on a first sidewall of the sidewall means with an air output located on a second sidewall of the sidewall means angularly disposed relative to the first sidewall of the sidewall means. A particle sensor including a fan is located within the housing and interposed between the air input and the output for sensing the number of particles passing between the air input and the air output. Preferably, a temperature and humidity sensor, a volatile organic compound (VOC) sensor and a carbon dioxide (CO2) sensor are provided for sensing the ambient air. A transmitter may be included for transmitting data from the particle sensor.

Abstract: An input plenum is disclosed for mounting to an air conditioning/heating unit. The input plenum comprises an air filter track for introducing and removing the air filter. A grid array track is located within the input plenum. The grid array track enables a grid array and an electronic generator to be added to the plenum to upgrade the plenum into an air purification system. An improved one-piece grid may be incorporated into the grid array for generating an electric field in the air purification system.

Abstract: An improved ceiling mounted air treatment system is disclosed for installation upon a ceiling grid system having a plurality of ceiling panels within a room. The improved ceiling mounted air treatment system comprises a ceiling plenum defining a plurality of side walls, a top wall and a bottom wall. The plurality of side walls are dimensioned for replacing a ceiling panel of the ceiling grid system. An air input and an air output are defined in the bottom wall. A grid array is disposed within the plenum and located between the air input and the air output. An electronic generator is connected to the grid array for treating the flow of air through the grid array. A fan is interposed between the air input and the air output for establishing the flow of air from the room into the air input to exit from the air output into the room.

Abstract: Air purification system where air is subjected to complex electrical field resulting from a DC voltage and AC frequency in kilovolt and kilohertz range respectively, applied to screen assembly in air path. DC amplitude and AC frequency self regulate to selected parameters. Parameters are selectable independently of one another.

Abstract: An air purification system for subjecting air to a complex electrical field including sensors and a monitor/controller for monitoring effectiveness, operational conditions of the electrical field and the system, and ambient conditions of the air being purified. The level of the high voltage, RMS and high frequency is processed so that frequency, RMS and high D.C. can be measured at a low D.C. voltage.

Abstract: This invention relates to an improved method and apparatus for the detection and measurement of concentrations of foreign substances in a fluid, particularly atmospheric gas. Transducers and signal modifying devices are electronically connected in a predetermined arrangement so as to determine the concentration of foreign matter and display this concentration as a linear function determined by the amount of foreign matter found.

Abstract: An electrodynamic gas charge system comprising at least one electrically charged element and screen element arranged relative to each other to form a voltage gradient therebetween wherein the system includes means to vary the voltage gradient between the electrically charged element and screen element, the elements being disposed across a gas flow such that particles of dissimilar substances are separated by the charged force field and recombined with like particles.
