Abstract: 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.

Abstract: A Heating, Ventilating Air Conditioning (HVAC) fan control method to detect an HVAC fan is controlled by at least one fan-on duration control selected by a user and provide at least one fan-on alarm message prior to overriding the at least one fan-on duration control. The method monitors an occupancy sensor signal to determine an occupancy in a conditioned space served by an HVAC system and automatically overrides the at least one fan-on duration control to save energy when the conditioned space is unoccupied. The overriding may comprise operating the HVAC fan based only on a thermostat call for cooling or a thermostat call for heating, operating the HVAC fan for less time than the at least one fan-on duration control selected by the user, and operating the HVAC fan for less frequency than the at least one fan-on duration control selected by the user.

Abstract: An ambulatory infusion pump can include a maximum bolus override procedure. When a bolus amount greater than a maximum bolus amount is requested, the pump can provide an alert indicating that the amount requested exceeds the maximum bolus amount. If the user confirms the request in response to the alert, the bolus amount can be delivered to the user. The amount delivered in response to the confirmation can be a first portion of the bolus amount. A reminder can then be provided that a second portion of the bolus amount that is a remaining portion of the requested bolus amount was also requested. If a second confirmation is received in response to the alert, the second portion of the bolus amount can also delivered to the user.

Abstract: 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.

Abstract: A lock includes an electrically powered locking mechanism operable between locked and unlocked positions, a power supply, and a controller for operating the locking mechanism between locked and unlocked positions. The controller regulates the amount of electric power supplied to the electrically powered locking mechanism and determines temperature in the vicinity of the locking mechanism, and is capable of supplying first and second levels of electric power to the electrically powered locking mechanism in accordance with the temperature in the vicinity of the locking mechanism. If the temperature in the vicinity of the locking mechanism is within a predetermined temperature range, a first level of electric power is supplied to the electrically powered locking mechanism to operate between locked and unlocked positions. If the temperature is below the predetermined temperature range, a second, lower level of electric power is supplied to the electrically powered locking mechanism.

Abstract: 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.
