Abstract: In one embodiment, an ink cartridge comprises an outer housing that defines an interior space adapted to contain ink and an air vent adapted to enable air to pass into and out of the interior space and a dividing wall provided within the interior space, the dividing wall separating the interior space into a first chamber and a second chamber, the dividing wall defining a passage through which air within the first chamber can pass into the second chamber and out of the cartridge through the air vent when the air within the first chamber expands.

Abstract: A stray-wire sensor includes a vertical magnetic gradiometer (VMG) carried over the surface by ground vehicles or by low-flying aircraft. The VMG has a spot of sensitivity on the ground which stays nadir to the VMG itself. A Faraday shield surrounding the VMG screens out the near field electric dipole signals, and a ferrite rod core and winding inside act as an antenna sensitive to the near-field magnetic dipole signals which radiate from horizontal lying stray wires on the ground surface in the dirt of hidden by ground cover. The VMG depends on it being moved around over the ground so that magnetic signal gradients and reversals can be measured point-by-point. The nadir points which fall over a point along a long horizontal wire will express characteristic signatures in the signal gradients and phase reversals measureable in the antenna.

Abstract: A fluid cartridge for a printing device includes a housing including a floor, a chamber defined in the housing and configured to store an ink therein, a capillary medium disposed in the housing and in operative communication with the chamber, and a wick disposed at least partially in an opening of the floor, the wick including a portion extending a predetermined distance into the housing such that the wick portion contacts the capillary medium. The fluid cartridge further includes an enriched pigment-confining member established inside the housing such that the confining member physically contacts the floor and surrounds at least a portion of a periphery of the wick. The confining member is configured to i) block enriched ink from the wick, and/or ii) dilute the enriched ink prior to flowing through the wick.

Abstract: A fluid cartridge for a printing device includes a housing having a base and a first and second chamber. A wall extends outwardly from and substantially normal to the base and is configured to separate the housing, thereby forming the first and second chambers. An air/ink exchange port is defined in a bottom portion of the wall and adjacent to the base. A longitudinal air flow-restricting member is disposed adjacent the air/ink exchange port and on the base, and extends outwardly predetermined distance into one of the first or second chambers.

Abstract: A fluid container includes a body having a depth extending between a base interior surface and an opening of the fluid container. The fluid container also includes a capillary material compression structure having an extension depth extending from the opening to a capillary material where the capillary material compression structure is in contact with the capillary material, and the ratio of the extension depth to the depth is 0.35 or greater.

Abstract: Scanning fiber devices are disclosed. In one aspect, a scanning fiber device may include an actuator tube. The scanning fiber device may also include a cantilevered free end portion of an optical fiber. The cantilevered free end portion of the optical fiber may have an attached end that is coupled with the actuator tube. The cantilevered free end portion of the optical fiber may also have a free end to be moved by the actuator tube. At least a portion of a length of the cantilevered free end portion of the optical fiber may be disposed within the actuator tube. Methods of using scanning fiber devices are also disclosed.

Abstract: A fluid container, including a body having a base surface, a capillary fluid volume disposed over the base surface, and an outlet compartment having at least one outlet wall disposed within the body and extending from the base surface into the capillary fluid volume. The body also includes at least two fluidically segregated free fluid compartments, where each compartment includes at least one sidewall disposed within the body. The at least one sidewall includes a compression edge wherein at least a portion of the compression edge is flush with the at least one outlet wall edge.

Abstract: A container includes a housing forming at least one chamber therein, a fluid conduit having a fluid opening extends into the chamber, and a fluid holding member is arranged within the chamber over the fluid opening. The fluid holding member leaves at least one air pocket within the chamber adjacent to the fluid conduit. When the fluid holding member is at least partially filled with a fluid it will have at least one wetted portion and at least one non-wetted portion. The wetted portion is fluidically coupled to the fluid conduit. The container also includes at least one feature within the chamber to provide an air passageway that allows air movement between the air pocket and at least the non-wetted portion.

Abstract: A system for detecting Barrett's metaplasia utilizes an illumination and imaging probe at the end of a catheter. The probe illuminates the wall of the esophagus and returns reflected light to be processed to provide a visual indication of the color of the esophageal wall. The position of the probe along the length of the esophagus is also measured to allow a medical practitioner to determine the location of the transition from the pink stomach lining to the white esophageal lining.

Abstract: A frame having a passageway is movably mounted on retractable wheels. A removable tongue is connected to the frame for transporting the spray machine. A spray system is mounted on a spray arch having a plurality of nozzles along its length and the spray arch is provided with sleeves at the bottom ends of its legs for slidably engaging vertical posts in the frame whereby the spray arch may be selectively vertically adjusted. The posts are provided with horizontal sleeves slidably connected to horizontal members of the frame for horizontally adjusting the position of the spray arch. The spray for the spray system is supplied from a tank mounted on the frame which in turn is connected to a pressurized air tank. An actuating wand extends transversely across the passageway through the frame to be engaged by an animal and maintain contact with the animal along its entire length such that that the animal will be sprayed.
