Abstract: The invention relates to a device for inspecting a damage or a crack of part of a hydro turbine, comprising at least one underwater remote operated vehicle (20) or autonomous underwater vehicle, at least one floatable or buoyant probe (26) or at least one probe (26) and means to make said at least one probe floatable, said probe comprising at least one imaging device (32) and/or laser scaler, and means for transmitting data from said probe to said vehicle or to a ground station when it is distant from said vehicle.

Abstract: Assistive movement devices and methods therefor are provided that are capable of redirecting loads from an individual's foot to hip when an individual is recovering from an injury at or below the knee. The devices include a frame assembly comprising an upper member, a lower member, and a joint therebetween. An upper attachment is secured to the upper member and is configured to be secured to the thigh of the individual's leg, and a lower attachment is secured to the lower member or the base and is configured to be secured to a portion of the leg below a knee thereof. A base is secured to the lower member and is configured to support a foot of the leg, and the device adjustably redirects at least a portion of a load resulting from the individual standing and walking from the base to the upper attachment.

Abstract: The invention relates to an apparatus and method for the detection of the spectral absorption properties of a fluid in a microenvironment, the apparatus comprising a radiation source, a microfluidic device and detection means, wherein the apparatus additionally comprises means for increasing the path length of the radiation through the fluid. Preferably, the means for increasing the path length of the radiation through the fluid comprises two highly reflective mirrors which cause the base path length through the fluid to be increased by many orders of magnitude, and the method comprises Cavity Enhanced Absorption Spectroscopy. The method is especially useful for the handling of small volumes of fluids for chemical and biological processing.

Abstract: An automatic resetting apparatus for a water sound-source which apparatus includes a source of high pressure resetting liquid, conduit means for connecting the source to the sound-source, a valve in the conduit means, which valve is, in use, under the direct or indirect influence of an actuating pressure of a sound source charging fluid, is actuable from a first position to a second position at a predetermined low actuating pressure within the charging fluid and will remain in said second position until the pressure within the charging fluid falls to said predetermined low pressure, whereupon the valve returns to the first position, the second position allowing the resetting liquid to pass along the conduit means to reset the sound-source and the first position allowing discharge of the resetting liquid from the sound-source after the sound-source has been reset.
