Abstract: At least one aspect is directed to a device to configure a fire sprinkler. The device can have an elongated member. The elongated member can have an open end, an opposing closed end, and a body extending laterally therebetween. The open end can receive a portion of a fire sprinkler. The closed end can have a main aperture. The main aperture can receive a portion of a ratcheting socket wrench drive. The closed end can have at least one surrounding aperture. The surrounding aperture can be positioned apart from the main aperture to define a solid partition therebetween. The solid partition can have non-uniform thickness between the main aperture and the at least one surrounding aperture.

Abstract: An impact test apparatus can be used to determine particle interfacial energies with varying relative air humidity. It was observed that capillary condensation increased the adhesive forces of hydrophilic materials. A systems humidity separation window was identified and the differences in interfacial energy for a hydrophilic surface and for a hydrophobic surface can be exploited in order to achieve the separation of particles. Separation and concentration of particles, particularly particles within a mineral ore body, can be obtained.

Abstract: The present invention relates generally to using upconverting inks for producing highly-resolved patterns for inter alia, security applications. More specifically, the present invention relates to the use of sols (inks) and printing processes that produce well-defined printed features consisting of polymers impregnated with luminescent upconversion nanocrystals. The patterns printed using such inks and processes may exhibit defined shapes, characters of text, and various other types of images.

Abstract: An automated guided vehicle system including at least one automated guided vehicle (AGV) for following predetermined magnetic paths on a ground surface to carry cargo to selected points on the paths. The AGV includes a chassis, top plate mounted on the chassis for receipt of cargo, a pair of driving wheels coupled to driving motors, and plural passive omni-wheels. Control and navigation circuitry is provided to operate the motors to drive the driving wheels to cause the AGV to follow a desired one of the paths. The AGV provides illumination indicating its direction of travel and status. It also includes laser scanners for obstacle detection.

Abstract: An improved system and method for reading an upconversion response from nanoparticle inks is provided. A is adapted to direct a near-infrared excitation wavelength at a readable indicia, resulting in a near-infrared emission wavelength created by the upconverting nanoparticle inks. A short pass filter may filter the near-infrared excitation wavelength. A camera is in operable communication with the short pass filter and receives the near-infrared emission wavelength of the readable indicia. The system may further include an integrated circuit adapted to receive the near-infrared emission wavelength from the camera and generate a corresponding signal. A readable application may be in operable communication with the integrated circuit. The readable application receives the corresponding signal, manipulates the signal, decodes the signal into an output, and displays and/or stores the output.

Abstract: The present technology relates generally to a stable oil-in-water emulsion containing upconverting nanoparticles. In particular, the present technology relates to an ink formulation comprising a stable oil-in-water emulsion of upconverting nanoparticles useful for security printing. Preferably the upconverting nanoparticles comprise a ?-Na(RE)F4 nanoparticle, wherein RE is a lanthanide, yttrium, or a combination or mixture thereof.

Abstract: A sequence of symbols is generated to describe a set of write data, the symbols having a length of nT, where T is a channel clock rate and n is an integer over a predetermined range. Bi-directional write currents are applied to a write pole to record the sequence of symbols to a magnetic storage medium. The write pole has an effective footprint with a downtrack length of mT, where m is an integer. The write currents are switched between a first rail current and a second rail current for alternating symbols, the write currents further transitioning to an intermediate current value for at least one channel clock period for symbols longer than 1T. Write currents are applied to the write pole when recording symbols having a length longer than mT using the effective footprint of the write pole as an interval.
