Abstract: Hydrogen gas sensors with low cost, fast response time, large detection range, high sensitivity, and excellent limit of detection are described. The devices include a composite formed on a nano-scale that both absorbs hydrogen and exhibits magneto-optical effects. Sensor readout is based on magneto-optical effects, which also may be enhanced through plasmonic coupling. The hydrogen sensors are fast and sensitive, as well as resistant to surface poisoning from common contaminants, such as carbon monoxide.

Abstract: A connector interface system includes a cap to connect to a reservoir to form a reservoir/cap unit for installation into an infusion pump device. The cap has at least one receptacle for receiving one or more detectable features comprising at least one disc-shaped member, for detection by at least one sensor element on the infusion pump device when the reservoir of the reservoir/cap unit is received in a reservoir receptacle of the infusion pump device. The at least one detectable feature has at least one detectable parameter that is associated with one or more characteristics of the cap, the reservoir, the infusion pump device, a cannula associated with the cap or a tubing connected between the cap and the cannula.

Abstract: Patient monitoring systems and related medical devices and methods are provided. One method involves obtaining historical usage data associated with a patient for a plurality of potential site locations for a medical device, classifying one or more site locations of the plurality of potential site locations into a viable group of potential site locations for the patient based at least in part on the historical usage data, and providing, at a client device, graphical indicia of the one or more site locations classified into the viable group of potential site locations.

Abstract: A flexible tubing for a cannula has a hollow tubing body having a length dimension from a first end to a second end, and an outer diameter of no more than 0.9 mm. The tubing body has a section of enhanced flexibility of a greater flexibility than one or more other sections of the tubing body. The section of enhanced flexibility is spaced from the first end of the tubing body by a distance D, where D is within a range of 3.0 mm to 5.0 mm for a flexible tubing having a length of about 9.0 mm, and where D is within a range of 1.0 mm to 2.9 mm for a flexible tubing having a length of about 6.0 mm.

Abstract: An apparatus and method can effectively detect both hands and hand shape of a user from images input through cameras. A skin image detecting skin regions from one of the input images and a stereoscopic distance image are used. For hand detection, background and noise are eliminated from a combined image of the skin image and the distance image and regions corresponding to actual both hands are detected from effective images having a high probability of hands. For hand shape detection, a non-skin region is eliminated from the skin image based on the stereoscopic distance information, hand shape candidate regions are detected from the remaining region after elimination, and finally a hand shape is determined.

Abstract: A downhole tool includes a housing defining a passageway therethrough exhibiting a first diameter and a second diameter that is smaller than the first diameter, and a first turbine disposed in the first diameter of the housing. The downhole tool further includes means for measuring a rotational velocity of the first turbine, a second turbine disposed in the second diameter of the housing, and means for measuring a rotational velocity of the second turbine.

Abstract: The present invention provides a cement composition and a process for using the cement composition to inhibit gas migration from a subterranean zone into the cement. The process comprises displacing a gelling additive, preferably comprised within a cement composition, into a well bore such that the gelling additive passes into the subterranean zone, and allowing the gelling additive to form a crosslinked gel in the subterranean zone to inhibit gas migration from the subterranean zone. The crosslinked gel acts as a barrier to gas in the subterranean zone and thereby inhibits the gas from passing into the cement and forming flow channels therein before the cement can set.
