Abstract: A method for characterizing gas emissions includes sampling each of a plurality of sectors having a common geographic center. For each sector, a first laser beam is transmitted from the geographic center to a first retroreflection location, where it is retroreflected into a first retroreflected beam. Near the geographic center, the first retroreflected beam is measured to obtain a first absorption. A second laser beam is then transmitted from the geographic center to a second retroreflection location, where it is retroreflected into a second retroreflected beam. Near the geographic center, the second retroreflected beam is measured to obtain a second absorption. The first and second retroreflection locations are both located within the same sector. First and second concentrations are determined from the first and second absorptions and processed to determine emission information about a known or potential gas source whose source lies within the sector.

Abstract: A rescue guidance system includes a thermal imager mountable on a self-contained breathing apparatus pack and capturing thermal image data of an area at least partially surrounded by a wearer including and a display unit configured for mounting within a face shield associated with the self-contained breathing apparatus in a field of view of the wearer. The display unit has a plurality of LED light elements configured as directional indicators relative to the wearer. A controller receives the image data and determines a location of a person within the thermal image data and correlates the location of the person within the thermal image data to an approximate location of the person relative to the wearer and illuminates a selected one of the plurality of directional indicators approximately corresponding with a direction of the location of the person relative the wearer.

Abstract: A method for characterizing gas emissions includes measuring first and second optical beams to generate first and second absorption signals, respectively. Each of the optical beams is transmitted from a center point and retroreflected back to the center point. Paths of the optical beams define boundaries of a sector. Based on the absorption signals, an emission rate of a gas from within the sector is determined. If the emission rate exceeds a threshold, a third optical beam is measured to generate a third absorption signal. The third optical beam is transmitted from the center point and retroreflected back to the center point. The third optical beam propagates along a path that divides the sector into first and second subsectors. Based on the first, second, and third absorption signals, a location of a source of the gas is identified as being within the first subsector or the second subsector.

Abstract: A powder treatment system with variable speed of rotation of a treatment vessel containing the powder at different stages of the treatment process. During treatment stages where gas flow may be present (e.g., pump down), the treatment vessel is spun at a centrifugal speed in order to confine the fine powder particles within the treatment vessel and prevent or substantially minimize elutriation losses. During treatment stages where gas flow may be minimal or not present (e.g., treatment dwell time), the rotational speed of the treatment vessel is a cataracting speed in order to uniformly treat the fine powder particles whilst avoiding or substantially minimizing elutriation losses.

Abstract: Methods and systems for performing dose regimen modification are provided. The methods and systems perform operations comprising: receiving prescription related data for treating a patient with an expected level of efficacy, the prescription related data comprising medication regimen information including dose and interval; determining, using a model, a first amount of drug waste based on the prescription related data; comparing the first amount of drug waste to a threshold value; and in response to determining that the first amount of drug waste transgresses the threshold value, identifying an alternate medication regimen that is associated with a treatment having a given level of efficacy corresponding to the expected level of efficacy, the alternate medication regimen being associated with a second amount of drug waste that is lower than the first amount of drug waste; and triggering a notification associated with the alternate medication regimen.

Abstract: A tufted article (e.g., an artificial turf panel) having a backing and a plurality of tufts extending through the backing. The plurality of tufts are distributed among a plurality of patterned regions. Each patterned region has at least one tuft of the plurality of tufts. The tufts of each patterned region differ from the tufts of at least one other patterned region of the tufted article in at least one of color, pile height, yarn type, or yarn density.

Abstract: A dual-beam optomechanical steerer includes first and second rotators mounted to a two-axis gimbal system. Each rotator is adjustable to control the azimuthal and elevation angles at which an optical transmitter affixed to the rotator transmits a beam of light. Thus, the two-axis gimbal system orients two optical transmitters identically while the first and second rotators orient the two optical transmitters independently with respect to the two-axis gimbal system. Examples of each rotator include a tip-tilt stage, goniometer, and rotation stage. Alternatively, a deflector may be used instead of each rotator. Examples of the deflector include an acousto-optic deflector, translatable lens, and Risley prism. The dual-beam steerer may be used to perform remote gas detection with two separate optical beams.
