Abstract: An air purifier and air treatment basket for inside air. The air purifier includes a housing. The air treatment basket is disposed in the housing. The air treatment basket includes an air treatment basket frame and a plurality of selectively removable air treatment panels containing filter media.

Abstract: A media basket assembly for use with an air purifier, such as but not necessarily limited to media basket assembly suitable for use with a vertical airflow type of air purifier. The media basket assembly may include a filter media configured to filter the airflow and a basket for positioning the filter media relative to a lower fan shroud of the air purifier.

Abstract: An air purifier and air purifier accessory for inside air. The air purifier includes a housing and an air outlet. The air purifier accessory is disposed on the air outlet. The air purifier accessory includes a frame containing a filter media, the frame adapted to be mounted at least partially over the air outlet of the air purifier to filter air discharged from the air purifier.

Abstract: Electrosurgical systems and methods are provided for RF nerve ablation, wherein a control console has multiple RF amplifiers associated with multiple channels, and multiple DC power supplies each dedicated to a corresponding one of the RF amplifiers. Each of a plurality of power supply relays are coupled between one of the DC power supplies and the dedicated corresponding one of the RF amplifiers. A controller is configured to apply switching signals to control each of the power supply relays to selectively switch on and off connections between the DC power supplies and the dedicated corresponding RF amplifiers. The controller may apply control signals to each RF amplifier sequentially, one at a time, to deliver energy separately and independently to each of the corresponding channels. The controller may be configured to apply the switching signals to self-grounding relays to selectively switch on and off connections between the channels and return relays.

Abstract: A dishwasher appliance includes a cabinet having a wash chamber for receipt of articles for cleaning, a rack assembly slidably received into the wash chamber and configured for the receipt of the articles, and a fluid dispensing assembly for dispensing a fluid onto the articles in the rack assembly during operation of the dishwasher appliance. Further, the dishwasher appliance includes a spot detection assembly. The spot detection assembly includes a transparent component and an imaging device arranged adjacent to the transparent component. As such, the imaging device is configured to detect one or more fluid spots on the transparent component, which is indicative of fluid spots being present on the articles.

Abstract: An ice making system includes an ice maker configured to form ice pieces therein with a top reservoir upstream of the ice maker and an ice bucket in communication with the ice maker. The ice making system also includes a recirculation tank and a recirculation pump. An oxidizing agent generator is configured to generate one or more oxidizing agents and provide the one or more oxidizing agents to form treated water within the ice making system.

Abstract: Electrosurgical systems and methods are provided for RF nerve ablation, wherein a control console is utilized with a passive or active cable accessory connecting to different of electrode attachments, such as monopolar and bipolar self-grounding types. The control console has multiple RF amplifiers that are associated with multiple channels of the control console and that are energized according to control signals non-simultaneously applied by a controller of the control console. The control console stores and processes identification data and usage data relating to cable accessories and electrode attachments that are connected or have been connected to the control console over time. The control console displays a representation of this processed data on a graphical user interface.

Abstract: A leak indicator includes a substrate comprising a permeable material with an immobilized reactant embedded in the substrate at a fixed location and a mobile reactant disposed at an initial location on the substrate. The initial location of the mobile reactant is spaced apart from the fixed location of the immobilized reactant. The mobile reactant is transported through the substrate by water to the fixed location of the immobilized reactant. The mobile reactant and the immobilized reactant interact to indicate a leak when the mobile reactant reaches the immobilized reactant.
