Abstract
A method and apparatus are described for measuring the concentration of a gas with an absorption band in the ultraviolet range. The device includes an absorption chamber containing a gas, a light source, a selected optical bandpass filter, and ultraviolet photodetectors. The gas concentration is measured by the ratio of a transmitted intensity to an incident intensity with the Beer-Lambert Law relation. A second light source may be used for a compensation signal. A second method periodically changes the absorption coefficient by inserting a transparent material in the absorption path to measure the optical compensation signal. A third method periodically shortens the optical absorption path by moving the active detector closer to the light source to measure the optical compensation signal. The fourth method uses an optical element to deflect the optical beam to create a shorter absorption path as a reference for the incident signal using one detector.

Abstract
A system to monitor weight of a reservoir or a structure comprises a load cell which comprises an electrical or optical transducer to provide a proportional signal of the deformation, a load cell base support for holding the load cell on the ground substantially about the axis of the support element of the reservoir, a load cell support adapter to attach the load cell to the support member of the reservoir. The cell support adapter may comprise an opening or a shouldering anchor aiming at facilitating attachment to a temporary lifting device.

Abstract
Dossier: 11439-080 Abrégé Un conditionneur de signal est divulgué. Le conditionneur de signal permet généralement de filtrer, convertir, segmenter ou de généralement conditionner l'alimentation électrique en amont d'un appareil électrique, tel une lampe aux DEL, de façon à ce que la lecture du signal électrique qu'en fait l'appareil puisse permettre de réaliser une fonction pratiquement exempte de variation induite par les fluctuations de la source et que l'énergie résiduelle soit vidée lors de l'interruption de l'alimentation.

Abstract
The invention relates to a signal conditioner. The signal conditioner can be used, in general, to filter, convert, segment or generally produce a waveform from a power source to obtain an electrical signal that is supplied to an electrical device, such as an LED lamp, such that upon reading the electrical signal the device allows a function to be performed that is practically free of variations caused by fluctuations in the source.

Abstract
A method and apparatus to monitor the weight of a silo or tank is disclosed. The system is adapted to be attached to a leg of the silo and comprises a load cell, a support member anchored to the ground and a lifting device attached to the load cell and to the support member. The load cell comprises two extremities that are attached to the silo leg and comprises an aperture there between. The aperture is preferably threaded to receive the lifting device, such as a bolt. The bolt is rotated using a tool as to induce a movement of the load cell along the axis of the bolt thereby lifting the load cell and the attached silo leg. Strain gauges are attached to the load cell to measure the variation in an electric or optical signal that is translated in human readable data using a monitoring device.
