Abstract: A pixelated mutual capacitance sensing configuration to detect the presence of floating water is disclosed. An integrated touch screen can be configured in a checkerboard arrangement of alternating drive pixels and sense pixels, where each drive or sense pixel can include a plurality of sub-pixels. The sense pixels can include sense sub-pixels surrounded by ground sub-pixels to reduce the baseline mutual capacitance between the drive and sense pixels. Stimulated drive pixels can capacitively couple onto the sense sub-pixels of the sense pixel, forming a baseline (no touch) mutual capacitance between the drive pixels and the sense sub-pixels. The presence of grounded objects shunts some charge to ground and reduces the mutual capacitance, while floating water provides and additional parallel mutual capacitance path that increases the mutual capacitance. Floating water can be distinguished from a grounded touch based on the direction of the change in mutual capacitance.

Abstract: Mitigation techniques can be used to reduce noise generated by wireless communication circuitry (e.g., near-field communication circuitry) in an electronic device including a display, touch, and wireless communication circuitry. In some examples, a touch screen can have a backplane including a mesh of routing traces connected to an array of chiplets. In some examples, the chiplets can repeat signals to prevent the accumulation of noise induced by an NFC coil. In some examples, the ratio between vertical and horizontal resistances of routing traces can be configured to mitigate noise induced by the coil. In some examples, the routing traces of the mesh can be configured to share a common geometric centroid. In some examples, a plurality of routing traces can be routed in a twisted pair configuration. In some examples, the routing traces and chiplets can be routed to minimize traversal through regions of relatively high electromagnetic field.

Abstract: Energy dissipation measurements in Frequency Modulation-Atomic Force Microscopy (FM-AFM) should provide additional information for dynamic force measurements as well as energy dissipation maps for robust material properties imaging as they should not be dependent directly upon the cantilever surface interaction regime. However, unexplained variabilities in experimental data have prevented progress in utilizing such energy dissipation studies. The inventors have demonstrated that the frequency response of the piezoacoustic cantilever excitation system, traditionally assumed flat, can actually lead to surprisingly large apparent damping by the coupling of the frequency shift to the drive-amplitude signal. Accordingly, means for correcting this source of apparent damping are presented allowing dissipation measurements to be reliably obtained and quantitatively compared to theoretical models.

Abstract: An assist assembly incorporated into a dispensing gun supporting an elongated cartridge containing a volume of a flowable material. An internally collapsible seating end of the cartridge is engaged by a rod and forward most plunger of the gun in order to force a flowable material through a forward disposed nozzle of the cartridge. A body contains a compressible spring and is mounted to the plunger so that the body contacts the internally collapsible seating end of the mounted cartridge. Forward advancing of the plunger results in a continuous force application by the spring in order to continuously and evenly dispense through the nozzle the flowable material. A secondary spring is mounted between a forward end of the cartridge from which the nozzle projects and an opposing forward end of the gun for additionally assisting in applying a controlled force discharge of fluid from the cartridge.

Abstract: A wastewater treatment system for removing contaminants from wastewater on a vessel using electricity. The wastewater treatment system may inject wastewater with one or more disinfectants or ionized gases, or both, to remove at least a portion of contaminants from the wastewater. The water treatment system may produce disinfectants from saltwater using one or more disinfectant generators and return the byproducts to a water body. The wastewater treatment system may also pass wastewater through an electrical coagulation unit in which an electrical current may be emitted into the wastewater, whereby flocculants are formed and cause suspended solids and other materials to settle out of the wastewater. The wastewater treatment system may include a secondary treatment system for further reducing concentrations of contaminants. In addition, the wastewater treatment system may include a solid waste treatment system for incinerating solids produced by the wastewater treatment system.
