Patent number: 10531772Abstract: A handheld vacuum cleaner including a suction inlet, a main body, a handle defined by a portion of the main body, a motor disposed within the main body operating a suction source, and a filter coupled to the main body. The filter is configured to separate debris from a flow of fluid drawn through the suction inlet. The filter includes a housing forming a first volume and a filter media forming a second inner volume. The filter media is coupled to the housing such that the first and second inner volumes together at least partially define a collection container configured to store debris separated by the filter media from the flow of fluid. The filter further includes an inlet opening that extends through the housing to provide fluid communication into the collection container such that the flow of fluid with the debris can flow into the collection container such that the flow of fluid with the debris can flow into the collection container and a relatively clean flow of fluid exits through the filter media.Type: GrantFiled: April 14, 2017Date of Patent: January 14, 2020Assignee: TTI (Macao Commercial Offshore) LimitedInventors: Robert Patrick Warren, Roderick Burgess, Joseph M. Lehman, Garry Fee, Michael Bloom, William Jacob Kozlowski, Jr., Steven Marcus

Patent number: 10470625Abstract: A vacuum cleaner including a suction inlet, a conduit in fluid communication with the suction inlet, a filter having a valve releasably connected to a filter inlet, the filter configured to collect debris drawn through the suction inlet. The vacuum cleaner further comprising a release mechanism moveable from a first position to a second position. In the first position, the filter is in fluid communication with the conduit to collect debris with the valve being open, and in the second position, the filter is disconnected from the conduit with the valve being closed. Movement of the release mechanism between the first and second positions closes the valve.Type: GrantFiled: April 14, 2017Date of Patent: November 12, 2019Assignee: TTI (Macao Commercial Offshore) LimitedInventors: Roderick Burgess, Robert Patrick Warren, Joseph M. Lehman, Garry Fee, Michael Bloom, William Jacob Kozlowski, Jr., Steven Marcus

Publication number: 20190170685Abstract: Methods described herein, in some embodiments, permit extraction of particle structural and/or surface charge data from gradient induced particle motion in channels. In one aspect, a method of manipulating particle motion comprises introducing a fluid into a channel, the fluid comprising particles, and driving particle accumulation to a preselected location in the channel by setting advective velocity of the fluid to offset diffusiophoretic mobility of the particles at the preselected location.Type: ApplicationFiled: December 5, 2018Publication date: June 6, 2019Inventors: Jesse AULT, Sangwoo Shin, Howard A. Stone, Jie Feng, Patrick Warren

Publication number: 20150130261Abstract: A method of designing and producing the spoke section of a vehicle wheel using chopped carbon fiber pre-impregnated composite material is provided, wherein the method allows wheel designers to machine several different wheel designs, wheel diameters, and wheels with different offsets without using different material molds for each, as is customary with traditional carbon fiber reinforced plastic wheels designed using a layup procedure. The present method greatly reduces material waste, engineering design effort for each wheel, and the cost of each wheel over existing methods by using a single mold that can accommodate different wheel designs.Type: ApplicationFiled: November 8, 2013Publication date: May 14, 2015Inventor: Patrick Warren
