Abstract: Systems and method for minimizing the impact of water vapor or other interferent analyte on analyte concentration measurements in a gas exchange measurement system. A system is includes a gas source, first and second gas analyzers coupled to first and second gas flow lines and configured to measure first and second concentrations of a target analyte in the first and second gas flow lines, respectively, a sample chamber configured to hold a water saturable sample, and a water vapor selective element and having a first and second inputs fluidly coupling the gas source to first and second sides, respectively, of the water vapor selective element, and at least one output fluidly coupling the first side of the water vapor selective element to the first and second gas flow lines and a second output coupling the second side of the water vapor selective element to the second gas flow line.

Abstract: A rocket motor includes a nozzle and a solid propellant section in communication with the nozzle. The solid propellant section includes a first energetic grain layer that has a top surface and a bottom surface, and a second energetic grain layer that has a top surface and a bottom surface. The second layer is located on top of the first layer. The bottom surface of the second energetic grain layer partially abuts the top surface of the first energetic grain layer, and the bottom surface of the second energetic grain layer and the top surface of the first energetic grain layer define a micro-void therebetween.

Abstract: Various assistive listening devices are coupled to a receiver integrated into a BTE sound processor of a cochlear implant system, or other hearing prosthesis. The assistive listening devices and manner of integration with the BTE sound processor may include, e.g., (a) integration of an FM (frequency modulated) receiver into a remote battery pack; (b) integration of an FM or infrared (IR) or other system into a custom all-in-the-ear hearing instrument shell with an electrical connection through an existing auxiliary connector in the earhook of a BTE sound processor; or (c) integration of an FM system into the BTE sound processor via an interposer module.

Abstract: A low-profile sweeper that employs rotary brushes. The low-profile sweeper is especially suited for low overhead clearance applications, as typically found in nut harvesting. The low-profile sweeper has an armature for locating one or more brushes in an array, or attached to a conventional agricultural sweeper. The armature attaches to a chassis or frame of a steerable drive. When used in a parallel oriented array, the brushes rotate in the same, common direction and in substantially the same, common plane of rotation, slightly skewed to avoid contact between the brushes. The bristles of the radial brushes are emanate fro a central hub and are approximately parallel to the plane of rotation. A fan can be utilized to aid the pick-up action of the brushes. The fan is preferably mounted to direct an airstream to the area to be swept. Also, a spray-bar can be attached to the armature or alternatively to the chassis, to aid in dust abatement.

Abstract: A container, for dispensing two substances simultaneously, that includes a neck portion having two orifices therein, a shoulder portion connected to the neck portion, and an elongated body portion connected to the shoulder portion, the body portion including two adjacent chambers sharing a common wall wherein each chamber is in fluid communication with an orifice in the neck portion, and wherein the two chambers are formed from different materials. The size and shape of the orifices can be varied to independently adjust the rate of dispensation of each of the two substances, or to compensate for variances in viscosity between the substances. The sizes of the two chambers can be varied independently from one another. Further, the two chambers can extend beyond the width of the common wall, to promote even and predictable deformation of the chambers when pressure is applied.
