摘要： The ionizer feedback control converts high-voltage signals to feedback signals to monitor the corresponding high-voltage signals and compares the feedback signals to a first specification to determine whether the feedback signals are within the first specification. The ionizer varies a frequency and a duty cycle of a digital signal to control an excitation signal for a step-up transformer and modulates the frequency and the duty cycle of a step-up transformer output voltage to consistently maintain the feedback signals within the first specification and maintain the high-voltage signals within a second specification to generate consistent ion concentrations over a range of electrical signal inputs. The microprocessor calculates and reports high-voltage signals, and ion concentrations based on feedback signals. The microprocessor monitors concentrations of Volatile Organic Compounds (VOCs) in an airflow serving the ionizer and adjusts the high-voltage signals and ion concentration when VOC concentrations are above a threshold.

摘要： A method for providing a variable fan-off delay after a thermostat call for cooling or after a heating on cycle for a Heating, Ventilation, Air Conditioning (HVAC) system. The variable fan-off delay may be ended based on comparing a measurement of a Conditioned Space Temperature (CST) to a CST threshold. The CST threshold may be based on a previous measurement of the CST monitored during the current variable fan-off delay. The CST threshold may be an inflection point where the rate of change of the CST with respect to time equals zero plus or minus a confidence interval tolerance. The CST threshold may also be a fan-off delay differential offset or a thermostat setpoint differential where the variable fan-off delay is ended when the measurement of the CST during the variable fan-off delay crosses the differential at least once after the cooling or heating on cycle.

摘要： A balanced bipolar ionizer that generates zero or nearly-zero ozone concentration by providing a bipolar ion concentration ratio greater than 80 percent based on a high-voltage output ratio less than 80 percent over a range of electric signal inputs. A signal-conditioning element provides an excitation signal to a step-up transformer which provides an output voltage to a positive and a negative voltage multiplier which provide a positive high-voltage output greater than an absolute value of a negative high-voltage output or vice versa. The high-voltage output ratio is equal to a minimum of an absolute value of a negative and positive high-voltage output divided by a maximum of the absolute value of the negative and positive high-voltage output. The bipolar ion-concentration ratio is equal to a minimum of an absolute value of a negative-ion and positive-ion concentration divided by a maximum of the absolute value of the negative-ion and positive-ion concentration.

摘要： An apparatus providing Fault Detection Diagnostics (FDD) for a Heating, Ventilating, Air Conditioning (HVAC) system comprising a permanent magnet attached to a movable damper and a magnetometer attached to a stationary frame to provide a magnetic field measurement of the permanent magnet. The apparatus converts the magnetic field measurement into a damper position measurement and determines a difference between the damper position measurement and a damper position actuator voltage command, and if the difference is greater than a damper actuator voltage tolerance, then the apparatus generates a FDD alarm signal. The apparatus calculates a com puted Outdoor Air Fraction (OAF) damper position based on a measured HVAC parameter, and if the difference between the computed OAF damper position and the OAF damper position command is greater than a damper position tolerance, then the apparatus generates a FDD alarm signal or an actuator voltage signal to correct the movable damper position.

摘要： A method is described to separate, characterize and/or identify microorganisms in a test sample. Said method comprises the steps of (i) lysing non-microorganism cells that might be present in the sample, (ii) separating the microorganisms as a pellet in the sample post-lysing non-microorganism cells, (iii) interrogating the pellet containing microorganisms by mass spectrometry to produce mass spectra of microorganisms, and (iv) characterizing and/or identifying microorganisms in the sample. The method may be used in characterizing/identifying microorganisms in complex samples, e.g., blood containing culture media.

摘要： A method for providing a cooling or heating variable fan-off delay based on a Conditioned Space Temperature (CST) measured during a current variable fan-off delay period compared to CST values measured during the current variable fan-off delay period. The method may also include turning off a cooling or heating system and continuing to operate an HVAC fan until the CST reaches an Inflection Point (IP) where a rate of change of the CST with respect to time (dT/dt) equals zero plus or minus a confidence interval tolerance. The method may also include providing a cooling or heating variable differential (or offset) and/or variable fan-off delay based on the duration of the thermostat call for cooling or heating, an off cycle time, a cooling temperature split, a heating temperature rise, outdoor air temperature, supply air temperature or a rate of change with respect to time of any of these HVAC parameters.

摘要： Apparatus and methods for Fault Detection Diagnostics (FDD) for a Heating, Ventilating, Air Conditioning (HVAC) system with an economizer to detect: 1) air temperature or relative humidity sensors failed/faulted, 2) dampers not modulating, 3) excessive outdoor air, 4) economizing when should not, 5) not economizing when should and 6) inadequate outdoor air. Economizer damper position is measured using at least one inertial Micro-Electro-Mechanical System (MEMS) device: 1) magnetometer, 2) accelerometer, 3) IMU and 4) rotatiometer. The magnetometer detects damper position using a small permanent-magnet attached to a movable damper and a MEMS device attached to the economizer frame. The accelerometer and IMU detect damper position using a MEMS device attached to the damper, and the ratiometer detects angular damper position. The methods determine whether or not the HVAC economizer, sensors, actuator and outdoor air dampers are functioning properly. If economizer faults are detected, then the method provides electronically-transmitted fault signals.

摘要： The efficient fan controller includes a microprocessor receiving at least one signal input from thermostat/equipment control terminals to control a fan relay to operate a system fan. The microprocessor monitors a thermostat call for cooling/heating duration and determines a variable fan-off delay based on the cooling/heating cycle duration, and at an end of a cooling/heating cycle energize the fan relay to operate the system fan for the variable fan-off delay. The fan controller avoids false thermostat activation signals and includes a common wire adapter to provide continuous power to a smart communicating thermostat and is configured to evaluate floating, zero, rectified, false positive and active input signals. The fan controller can be embodied on a forced-air-unit control board or thermostat. The fan controller installation methods ensure the system fan/blower operates at high speed for heating and cooling to improve thermal comfort, efficiency and satisfy the thermostat sooner to save energy.

摘要： Apparatus and methods for efficient HVAC fan control. The apparatus includes an efficient fan controller for direct-expansion air conditioning and gas furnace, heat pump, electric resistance, and hydronic heating systems. For gas furnace heating systems, the apparatus and methods include energizing the heater ventilation fan from the low speed used for heating to the high speed used for cooling after time period P1 to deliver more heating output to satisfy the thermostat sooner and save heat source energy. For heat pump, electric resistance, and hydronic heating systems the apparatus and methods include energizing the fan relay after a short fan-on time delay P0 based on the previous HVAC system off-cycle time P11. For all of these HVAC systems, the apparatus and methods vary the extended fan-off time delay P2 based on air conditioning compressor or heat source operational time P3.
