    摘要: A method for detecting surface impurities on a surface of a component by X-ray fluorescence analysis uses a hand spectroscope for application to the surface of a component. The hand spectroscope comprises an X-ray source, a fluorescent radiation detector, an analyzer and a display. The method comprises irradiating the surface of the component with X-rays using the X-ray source; detecting fluorescent radiation, which is emitted by the surface of the component as a result of the irradiation with the X-rays, using the fluorescent radiation detector; measuring a radiation spectrum of the detected fluorescent radiation; generating an evaluation result by analyzing the measured radiation spectrum using the analyzer, the evaluation result comprising a quantitative measure of the surface impurity of the surface due to predetermined characteristic substances; and outputting the generated evaluation result on the display.

    摘要: An elliptical system is disclosed having a crank assembly configured to be adjusted in length to accommodate users having varying gaits. In some embodiments, the crank assembly includes a crank and an axle connection bracket that is slidably adjustable with respect to the crank. For example, the crank assembly can include a crank link having a longitudinal body, where the longitudinal body is connected to the crank at one end and includes a longitudinal slot slidably coupled with the axle connection bracket. The axle connection bracket is configured to slide through a plurality of positions along the longitudinal body. In some embodiments, the crank assembly further includes a screw for adjusting the axle connection bracket with respect to the crank, where the screw can cause the axle connection bracket to slide through one or more positions of the plurality of positions when the screw is turned.

    摘要: An air delivery lock for a cargo located in an aircraft includes a housing, a restraining device having an engagement end for contacting and restraining the cargo, and a force reaction end, a bell crank having a bell crank joint for swivably mounting the bell crank, an elastically deformable force introduction unit, and a latching unit. The restraining device is swivably mounted on a leg of the bell crank around a restraining device axis. The force introduction unit is attached to a second leg of the bell crank and the force reaction end of the restraining device. A first guide attached to the housing and a second guide attached to the restraining device prevent rotation of the bell crank until a predetermined release force is reached on the engagement end of the restraining device.

    摘要: An apparatus for filtering solid and/or non-dissolved contaminants entrained in flowing water, the apparatus comprising an inlet for the water containing the entrained solid or non-dissolved contaminants to flow into a filtering chamber; a first outlet for expelling the unfiltered water from the filtering chamber; the filtering chamber further comprising: a curved or corner portion in the filtering chamber providing at least a part of a flow path of water from the inlet to the first outlet such that flow of the water along the curved or corner portion changes the direction of flow of the water; and a filtering screen for filtration of solid and/or non-dissolved contaminants from the influent water thereby allowing passage of filtered water out of the filtering chamber.

    摘要: Light emitter devices, components and methods are disclosed. In one aspect, a light emitter component of a light emitter device is disclosed. The light emitter component can include a silver (Ag) portion at least partially disposed over a surface of the component. The component can further include a protective layer at least partially disposed over the Ag portion, the protective layer at least partially including an organic barrier material that increases or improves chemical resistance of the Ag portion. In some aspects, the protective layer includes a polyxylylene (e.g., poly(p-xylylene), a substituted poly(p-xylylene), a fluorocarbon containing poly(p-xylylene), and/or any other polymer prepared from a xylylene and/or comprising —CH2—(C6H4)—CH2— based repeating units. In some aspects, the protective layer includes Parylene.

    摘要: A fiber composite component with integrated active electromagnetic shielding includes a fiber composite layer having reinforcing fibers, and an electric conductor, which extends on the fiber composite layer along the fiber composite layer and produces an electromagnetic field during operation, wherein a proportion of the reinforcing fibers is designed as conduction fibers, which are arranged to follow the electric conductor within the fiber composite layer and are designed to produce an opposing electromagnetic field during operation which attenuates the electromagnetic field of the electric conductor.
