A sensor system has a first sensor-element block and a second sensor-element block, at least one first sensor element and one second sensor element are assigned to the first sensor-element block, and at least one third sensor element is assigned to the second sensor-element block. The optical amplification fiber is wound while the curvature radius is being changed to provide a small-size, high-power fiber laser apparatus. The progressive jackpot is funded with an ante from each player who places a bet in the craps game. The sensor elements embedded in the collar’s band has at least one elastic pin extending toward the animal’s neck to gather data processed on the collar or remotely. The width of the inter-gate dielectric is narrower than that of the bottom gate pattern. for then proving possible influx of a back flow of liquid from the influx zones one assume implies the gas pressure and the inflow of a gas form the influx zones.
