摘要： The object of the present invention is to reduce the exposure of polluted air to a baby, and in particular to minimize the pollutions inhaled by a baby when strolling, walking or transporting a baby in an exterior environment. The object is attained by providing a portable device for filtering air, said device being adapted to be arranged in association with a top end of a baby-transporting device. With such an air-filtering device, air from outside of the baby-transporting device may be filtered and purified before being provided in a well-distributed manner to the area of the baby-transporting device where a baby is positioned.

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： An ionization device may be configured to be portable, and to rest on a surface such as a floor or desk top. The ionization device includes an air-intake port, an ion generator, an ozone catalyst for removing at least some ozone from air, and an air discharge. Air enters the device through the air-intake port, and at least some of the air is ionized to remove particulates. The air is then moved past or through the ozone catalyst to remove at least some of the ozone from the air. A controller may be used to monitor particulates, temperature, humidity, and/or other relevant factors and/or to adjust the ionization level.

摘要： An air purification system for use in a given location to remove or destroy harmful pathogens in the air. The air purification system has a housing with an inlet, an outlet, and a passageway extending between the inlet and the outlet. An intense field generator and filter is used to charge any particles in the air and remove them from the air flow. Finally, a dielectric barrier discharge unit having a high voltage electrode coupled to a dielectric barrier and a ground electrode spaced apart from the high voltage electrode is used to form a low temperature plasma chamber is in communication with the passageway so that the ions created in the plasma chamber will attach to and destroy any remaining particles in the air flow.
