摘要： An engine exhaust flow meter and method of measuring engine exhaust flow rate includes a flow tube and a differential pressure meter that is adapted to measure differential pressure in exhaust flow through the flow tube. A computer samples the differential pressure meter at a rate that is greater than the pulsation of exhaust flow to obtain a differential pressure signal. The computer is responsive to the differential pressure signal to compute a mean differential pressure value. The computer is responsive to the differential pressure signal to compute a mean magnitude of pressure pulses. The computer determines a compensation factor as a function of the mean magnitude of pressure pulses and adjusts the mean differential pressure value as a function of the compensation factor to obtain an engine exhaust flow value that is flow pulsation compensated.

摘要： There is disclosed a transdermal analyte sensor device. The device includes a sensor cartridge having a membrane permeable to a target analyte transdermally received from a subject, a reservoir containing a fluid to receive the target analyte through the membrane and an enzyme to react with the target analyte to form a byproduct, a working electrode to generate an electrical current based on a concentration of a byproduct, and a cartridge electrical contact to transmit the electrical current. The device also includes a device body having a device electrical contact to receive the electrical current from the cartridge electrical contact, a transmitter to transmit a signal based on the electrical current to a monitoring device, and a cartridge receptacle to receive the sensor cartridge and position the membrane to contact skin of the subject.

摘要： The present invention may be embodied as a retrievable device capable of sensing one or more properties of an individual (e.g., chemical or physical parameters). In use, the retrievable device can continuously determine the chemical concentrations within the vaginal tract. An embodiment of the retrievable device comprises a first housing having a light source and an image capture device, a second housing removably connected to the first housing and having a sensor, and a fitting for retrieving the device. The sensor may be an analyte sensor configured to obtain at least one measurement of a concentration of an analyte in a fluid. The analyte sensor comprises a sensor substance in a sol-gel material so the sensor substance reversibly interacts with an analyte of interest. In addition, the retrievable device can be configured to determine different physical parameters and re-implanted.

摘要： A propulsion engine for an aircraft comprises an enclosure having a longitudinal axis oriented in a direction of travel of an aircraft, the enclosure including a series of walls and a plurality of ducts arranged along the longitudinal axis. Each of the ducts including a number of walls that are either dynamic or static in movement. Each of the ducts includes a central axis that is angled at, or can be adjusted to, an angle toward the front wall of the enclosure such that a top end of each duct is toward the front wall of the enclosure. A fan is disposed in each of the ducts configured to generate airflow along the respective central axes from the top end to the bottom end to provide lift and thrust to the aircraft.

摘要： The invention broadly comprises a chemical composition including a plurality of cholesteryl esters arranged to form a vesicle. In several embodiments, all of the plurality of cholesteryl esters have a same molecular length, which in some embodiments provides a vesicle having a generally smooth outer surface, while in other embodiments, a portion of the plurality of cholesteryl esters have different molecular lengths, which in some embodiments provides a vesicle having a generally irregular outer surface. In yet further embodiments, a shape of the vesicle is selected from the group consisting of spherical, oval, disc-like, tubular and polyhedral shapes, and in yet other embodiments, a wall of the vesicle is selected from the group consisting of a monolayer and a bilayer. In still further embodiments, the chemical composition further includes a polyethylene glycol coat of mixed polymer size. In some embodiments, the plurality of cholesteryl esters include at least two different cholesteryl esters, and in some of these embodiments, the at least two different cholesteryl esters are selected from the group consisting of cholesteryl myristate, cholesteryl laurate, cholesteryl dodeconate, cholesteryl palmitate, cholesteryl arachidonate, cholesteryl behenate, cholesteryl linoleate, cholesteryl linolenate, cholesteryl oleate and cholesteryl stearate.

摘要： The present disclosure relates to methods and devices for amplifying a plurality of targets in a single PCR run while distinguishing between clinically relevant amplification and amplification from other sources such as from background contamination. The methods and devices further enable discrimination between gram-positive, gram-negative and fungal infections as wells as identify antimicrobial resistance genes. When applying the methods and devices of the invention, the species or genus of an infection(s), and genus of a fungal co-infection(s) or category of bacterial (gram-positive or negative) co-infection(s) are identified. Species identification of co-infections can also be achieved. Further, when applying the methods and devices of the invention, organisms which are likely to be contaminating organisms from a blood draw are identified.
