Patent number: 10244908Abstract: An embodiment of the system for transporting and collecting waste includes a movable receptacle configured to translocate from a first position to a second position and back again, and a vacuum system associated with the movable receptacle. The vacuum system includes a motor for generating suction and a power source connector associated with the motor. The power source connector is associated with the power source and transmits power to the motor when the movable receptacle is in the first position, and the power source connector dissociates with the power source, thereby interrupting power to the motor, when the movable receptacle moves away from the first position. The power source connector includes a connection terminus and a semi-flexible stem that flexes to allow a proper alignment between the connection terminus and the power source when the movable receptacle translocates from the second position to the first position.Type: GrantFiled: February 22, 2017Date of Patent: April 2, 2019Assignee: SIMPLAVATEInventors: Daniel R. Lilley, Clyde L. Witham

Patent number: 9610586Abstract: A system for transporting and collecting waste is disclosed. The system comprises a waste disposal bay comprising a front side, a bottom side, and a back side, wherein the back side includes an opening. The system further comprises a movable receptacle positioned above the waste disposal bay configured to translocate from a first position to a second position and back again, and wherein the movable receptacle comprises a through hole. The system further comprises a vacuum system associated with the through hole of the movable receptacle, comprising a motor for generating suction and a removable container for collecting waste; an attachment mechanism between the opening of the back side and the through hole, wherein the attachment mechanism is configured to maintain fluid communication between the opening and the vacuum system when the movable receptacle is in the first position; and a switch configured to activate the motor.Type: GrantFiled: January 15, 2016Date of Patent: April 4, 2017Assignee: SIMPLAVATEInventors: Daniel R Lilley, Clyde L Witham

Patent number: 9500569Abstract: The invention relates to low flow rate cascade impactors for sampling aerosols, notably but not limited to pharmaceutical aerosols. The impactor stages serve as both orifice plate and collecting cup, simplifying collection and analysis. The impactor is designed to operate at flow rates approximating the inspiratory flow rates of young children and infants. Also presented is a method of and apparatus for applying a coating material to the collection surface of the stages after an impactor is assembled for use. The method entails generation of a polydisperse aerosol and sampling into the impactor. The coating substance improves the trapping of particles on the stages. The apparatus and method of application limit the amount of coating material applied and confines it to the regions of particle impact opposite the stage orifices.Type: GrantFiled: January 25, 2014Date of Patent: November 22, 2016Inventor: Clyde L. Witham

Patent number: 8671874Abstract: Methods are presented for applying a coating material to the particle collecting regions and surfaces of the stages of a cascade impactor after the impactor is assembled for use. The methods comprise generation of a multimodal droplet aerosol of liquid coating material and delivering it into the impactor. The modes of coating droplet aerosol are selected to produce droplets that span the range of cutoff diameters for the stages of the cascade impactor. The coating substance improves the trapping of particles on the stages. The methods limit the total amount of coating material applied and confine it to the regions of particle impact opposite the stage orifices, thereby reducing the possibility of chemical interference when analyzing a test aerosol.Type: GrantFiled: March 17, 2010Date of Patent: March 18, 2014Inventor: Clyde L.
