Abstract: An intelligent assistant device is configured to communicate non-verbal cues. Image data indicating presence of a human is received from one or more cameras of the device. In response, one or more components of the device are actuated to non-verbally communicate the presence of the human. Data indicating context information of the human is received from one or more of the sensors. Using at least this data one or more contexts of the human are determined, and one or more components of the device are actuated to non-verbally communicate the one or more contexts of the human.

Abstract: A battery electrode composition is provided that comprises composite particles. Each composite particle may comprise, for example, active lithium fluoride/metal nanocomposite material optionally embedded into a nanoporous, electrically-conductive skeleton matrix material particle(s), where each of these composite particles is further encased in a Li-ion permeable, chemically and mechanically robust, protective outer shell that is impermeable to electrolyte solvent molecules. The active lithium fluoride/metal nanocomposite material is provided to store and release Li ions during battery operation.

Abstract: A method of removing material from a surface of a workpiece includes discharging a flow of fluid towards a workpiece at a pressure and a flow rate that facilitates forming a plurality of cavitation bubbles, and introducing abrasive media. The method includes exciting the abrasive media with the cavitation bubbles, removing material from the workpiece by an interaction between the cavitation bubbles and the abrasive media, and the surface of the workpiece.

Abstract: Information and passive biometric capture systems and methods. The information system includes a housing having a cavity configured to receive tangible items therein. A transparent, touch-sensitive display device is positioned over the cavity and configured such that in response to pixels of the display being black, the tangible items behind the black pixels are visible through the transparent display. A controller is programmed to receive from a remote server an alarm signal, and in response thereto, cause the display to change its state to indicate an alarm condition on the display. In response to receiving an input from the touch-sensitive display, a keypad is displayed, and inputs thereon are communicated to the remote server. The display can also display personal photographs stored in the memory device.

Abstract: The invention relates to a method for the leakage-proof storage of liquefied chlorine under increased pressure in pressure tanks, in which up to 20 wt. % polyvinyl chloride (PVC) or chlorinated polyvinyl chloride (cPVC) is placed in the pressure tank prior to filling the pressure tank with liquefied chlorine.

Abstract: Seismic data processing using one or more non-linear stacking enabling detection of weak signals relative to noise levels. The non-linear stacking includes a double phase, a double phase-weighted, a real phasor, a squared real phasor, a phase and an N-th root stack. Microseismic signals as recorded by one or more seismic detectors and transformed by transforming the signal to enhance detection of arrivals. The transforms enable the generation of an image, or map, representative of the likelihood that there was a source of seismic energy occurring at a given point in time at a particular point in space, which may be used, for example, in monitoring operations such as hydraulic fracturing, fluid production, water flooding, steam flooding, gas flooding, and formation compaction.

The lower hot-box portion (104) comprises a lower housing (142), a lower heating plate (144), and a lower insulation layer (148). The lower heating plate (144) is received within the lower housing (142) and is configured to support a lower die (106). The lower insulation layer (148) is positioned between the lower housing (142) and the lower heating plate (144). The upper hot-box portion (110) is positionable above the lower hot-box portion (104) and comprises an upper housing (186), an upper heating plate (188), and an upper insulation layer (192). The upper heating plate (188) is received within the upper housing (186) and is configured to support an upper die (112). The upper insulation layer (192) is positioned between the upper housing (186) and the upper heating plate (188).

Abstract: A hot-forming press (100) comprises a lower press assembly (102) and an upper press assembly (108). The lower press assembly (102) is movable along a vertical axis and comprises a lower die (106), and a lower hot-box portion (104), configured to receive the lower die (106). The upper press assembly (108) is movable along the vertical axis above the lower press assembly (102) and comprises an upper die (112), and an upper hot-box portion (110). The upper hot-box portion (110) is configured to receive the upper die (112) so that the upper die (112) is positioned opposite the lower die (106). The lower die (106) and the upper die (112) are configured to apply a forming pressure to a workpiece (114) that is received between the lower die (106) and the upper die (112). The lower hot-box portion (104) and the upper hot-box portion (110) are configured to heat the workpiece (114).

Abstract: A method includes receiving a first signal indicating a first movement in first predefined zone at a first time. A first activation signal is communicated to cause a first light source in the first predefined zone to be activated and provide downward illumination in the first predefined zone. A second activation signal is communicated to cause a second light source that in a second predefined zone to be activated and provide downward illumination in the second predefined zone. Responsive to an absence of receiving a second signal indicating a second/return movement in the first predefined zone at or before a second time that is after the first time, an alarm signal is transmitted that is indicative of an occurrence of a potential non-normal event.

Abstract: A method of cavitation peening may include coupling a moveable water source to a portable nozzle, through a flexible conduit. The method may include positioning the nozzle adjacent a treatment surface and discharging a first and second stream of fluid through a first and second channel of the nozzle, with the second channel concentrically positioned around the first channel. The first stream may have a first pressure, and the second stream may have a second pressure, the first pressure being greater than the second pressure and the two streams combining to generate a cloud of cavitation bubbles.
