    Abstract: The invention relates to towed acoustic transmitters forming an underwater vehicle which is itself intended for towing a linear acoustic receiving array (105). It consists in placing the vertical faired acoustic array (303) of such a transmitter at the very rear of the underwater vehicle, and in balancing the weight of this array by a faired ballast (313) situated at the very front thereof. These two parts are joined by a girder (310) of small cross-section, and the center of gravity of the whole is situated at the front of this girder and beneath it. The vehicle is towed by a cable (101) fastened to the vehicle by a hook (314) fixed to a swivel joint (315) above the center of gravity. It makes it possible to facilitate the operations of submersion and fishing-out of the whole while also achieving a greater depth of submersion.

    Abstract: A ultraviolet (UV) intensity indicator might use a UV responsive lumiphore to provide a converted, visible light level proportional to received UV light intensity for comparison to a visible brightness reference. For a desired UV intensity, the converted light should normally appear at least as bright as the reference light. For undesired UV, e.g. in a harmful wavelength range, the converted light should appear dimmer than the reference for normal operation and/or appear as bright as or brighter than the reference during excessive emission of the potentially hazardous UV emission. Alternatively, saturable lumiphores may provide different color outputs responsive to UV intensities for comparison to a multi-colored reference. Other examples contemplate use of a lumiphore to convert UV light to provide a visible light input to a visible light meter, such that an illuminance or brightness measurement by the meter gives a proportional representation of intensity of the UV light.

    Abstract: A particle-moving type orientation sensor including a housing, at least one light emitter, two light receivers, and a plurality of particles. The housing has an accommodating space having four zones, which are circularly arranged. A first opening is formed on the housing and connecting to a first zone. Two second openings are formed on the housing and respectively connecting to a second zone and a fourth zone. The light emitter emits light into the accommodating space through the first opening. The light receivers respectively receive light from the accommodating space through the second openings. The particles are arranged in the accommodating space. While the particle-moving type orientation sensor is tilting, the light emitter is partially blocked by the particles, and one of the light receivers is partially blocked by the particles, the light receivers respectively receive light with predetermined intensities and output electric signals with predetermined strengths.

    Abstract: The invention is a UV sensitive composition that undergoes a color change upon exposure to a predetermined dosage of UV-C radiation. The UV-C sensitive composition comprises a halogenated polymer, such as polyvinylidene chloride, that produces an acid upon exposure to UV radiation, and a pH sensitive dye. Upon exposure to UV-C radiation, the halogenated polymer undergoes degradation and produces HCl. The pH sensitive dye changes color as a result in an increase in HCl in the system. The composition may also include an acid scavenging composition and/or a diluent to control the amount of HCl produced in the system. The amount of HCl liberated from UV-C exposure may be selectively controlled so that a color change may be produced at a desired UV-C dosage. In some embodiments, the composition may be used to indicate a UV-C dosage from about 100 to 1600 mJ/cm2.

    Abstract: In order to determine the signature of an array of n seismic sources 21 to 27, for instance marine seismic sources in the form of air guns, the array is actuated and the emitted pressure wave is measured at n independent points whose positions will respect to the array are known by hydrophones 31 to 37. The measurements are processed to produce n equivalent signatures of the n sources taking into account the interactions therebetween. The signature of the array is then determined merely by superposing the n equivalent signatures.

    Abstract: A method for determining whether an item has been exposed to an environmental condition during a monitoring period. The method includes placing a sensor at least in proximity to the item at the beginning of the monitoring period so that the sensor will be exposed to a level of an environmental condition that can be correlated to an exposure level of the item to the environmental condition; reading the sensor; and determining from reading the sensor whether the item has been exposed to the environmental condition. The sensor includes a detecting material comprising a photochromic or photothermochromic material, the detecting material selected so that upon exposure to the environmental condition the detecting material exhibits a detectable color change.
