Patent number: 11167225Abstract: Trichomes, lupulins and other plant parts can be efficiently separated from plant biomass by continuous filtration. In some embodiments plant biomass is collected and combined with water to form a plant biomass mixture. The plant biomass mixture is passed through a filtration device in which the plant biomass mixture is continuously flowed through a filter material. The device includes a cleaning apparatus that cleans the filter material during the process. In some embodiments greater than 90% of the plant parts are collected from the starting plant biomass. The plant parts can be subsequently processed to obtain desired compounds. For example, trichomes can be separated from other plant biomass and subsequently processed to extract one or more cannabinoids or terpenes, such as THC and/or CBD.Type: GrantFiled: January 17, 2020Date of Patent: November 9, 2021Assignee: Spiral Water Technologies, Inc.Inventors: David Levitt, Jamie Yosha

Publication number: 20170352188Abstract: A portable display device is operative to modulate the appearance of a real or virtual image in response to the motion of the display device with respect to its relative movement with respect the object's virtual position. The display in effect becomes a portable window into a virtual world. The virtual object can be created from a real object by image capture and can be 2 or 3 dimensional. Specific modes of display movement can be used to infer a relative movement of the display window with respect to the one or more objects in the virtual world.Type: ApplicationFiled: October 12, 2015Publication date: December 7, 2017Applicant: Pantomime CorporationInventor: David A.

Publication number: 20170128859Abstract: Fluid filtration devices and methods of filtering fluids are described. The devices generally include a housing, a hollow filter assembly, a rotating cleaning assembly and a device to measure the accumulation of solids in the filter housing. In some embodiments the accumulation of solids is measured by measuring the torque required to rotate the cleaning assembly. Torque may be measured directly, such as with a torque sensor, or indirectly, such as by measuring the current used by an electric motor to drive rotation of the cleaning assembly. In some embodiments a purge valve is opened to remove accumulated solids from the housing when a certain level of solids accumulation is detected.Type: ApplicationFiled: November 9, 2016Publication date: May 11, 2017Inventors: David Levitt, Jamie Yosha, Steve Sokol, Dante Fernandez

Patent number: 7856410Abstract: A system is disclosed that provides a goal based learning system utilizing a rule based expert training system to provide a cognitive educational experience. The system provides the user with a simulated environment that presents a business opportunity to understand and solve optimally. Mistakes are noted and remedial educational material presented dynamically to build the necessary skills that a user requires for success in the business endeavor. The system utilizes an artificial intelligence engine driving individualized and dynamic feedback with synchronized video and graphics used to simulate real-world environment and interactions. Multiple “correct” answers are integrated into the learning system to allow individualized learning experiences in which navigation through the system is at a pace controlled by the learner.Type: GrantFiled: June 22, 2001Date of Patent: December 21, 2010Assignee: Accenture Global Services LimitedInventors: Olivia Ruth Burgess, Benoit Patrick Bertrand, Joseph Michael Ciancaglini, Lauren E.

Publication number: 20070045168Abstract: A variety of improved hydroclone based fluid filtering systems are described. The hydroclones generally include a tank having an internal chamber and a filter (preferably a surface filter) that is positioned within the internal chamber. The filter defines a filtered fluid chamber within the internal chamber of the tank. The hydroclone may be operated such that a vortex of flowing fluid is formed between the chamber wall and the filter with the filter being located in the center of the vortex. With this arrangement, the filter acts as a cross-flow filter. In one aspect of the invention, the filter is a stepped filter. In another aspect of the invention, the filter is an surface filter, as for example, an electroformed metal surface filter. In some preferred embodiments, the openings in the filter are arranged as slots that extend substantially vertically so that they are oriented substantially perpendicular to the flow path of fluid flowing in the adjacent portion of the vortex.Type: ApplicationFiled: August 18, 2006Publication date: March 1, 2007Inventors: David Levitt, Frank Dutro

Publication number: 20020151327Abstract: A custom handheld system, or system to adapt a personal mobile computing device, such as a handheld Personal Digital Assistant (PDA) or cellular telephone, to enable a user to enact and review media choices through wireless control of media-playing devices by the handheld device, and to present media directories on its display. Access to information that enables content directory choices, such as TV program schedule items or CD music track titles, is provided through the native Internet, modem, or other network connectivity of the handheld device. The system provides for uniform interfaces for control and content choices on different media player devices, and provides ways to use the limited handheld device's physical button interfaces to enable audio muting and personalized content surfing with one hand, without requiring use of the handheld device's stylus or touch sensitive display screen.Type: ApplicationFiled: December 20, 2001Publication date: October 17, 2002Inventor: David Levitt

Patent number: 6320598Abstract: Existing media signals are processed to create new media content by defining content representations for the existing media and establishing functional dependencies between the representations. The content representations comprise different data types which determine the kinds of operations that can be performed and dependencies that can be established. Among the types of transformation that can be achieved are synchronization, sound substitution, and the creation of parametric special effects. The content representations and their functional dependencies are combined to construct a functional dependency network which causes the desired transformations to occur on input media signals. The inputs to the functional dependency network are parametrically specified by media data types to construct a template that can be used to create adaptive media productions.Type: GrantFiled: March 28, 2001Date of Patent: November 20, 2001Assignee: Interval Research CorporationInventors: Marc Davis, David Levitt
