The invention generally comprises creating a signal conditioner that is capable of filtering, converting, segmenting and producing a periodic waveform from an electrical source, converting in into an electrical signal to drive an electrical device, such as a LED lamp, so that the behavior of the device driven by the electrical signal enables the device to perform a function that is practically free of the variations present in the main electrical source.

METHOD AND APPARATUS FOR LONG TERM ACCURATE MEASUREMENT OF AMMONIA GAS CONCENTRATION IN A PERMANENT AMMONIA GAS ENVIRONMENT
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.

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 loadcell 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.

Method and apparatus to monitor a reservoir or a structure
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.
