            <link>http://www.freepatentsonline.com/8111076.html</link>
            <description><![CDATA[This invention is concerned with a method for measuring the canopy rehydration pulse during the period of water application. During the rehydration process water leaks from the trunk xylem tubes into the sapwood extraxyllary region. A water content sensor in this region monitors the magnitude and timing of this leakage water thereby giving a measure of the magnitude and timing of the upward flow of water. The rehydration pulse is quantified by a sequence of measurements of sapwood water content: an initial measurement of water content just prior to water application, then measurement of water content during water application. The difference between the values obtained in the two measurements yields a measure of the leakage water in the extraxyllary region and, in turn, the magnitude and timing of the rehydration pulse. Determination of the onset and termination of the rehydration pulse is used to optimize the duration of water application.]]></description>

            <description><![CDATA[A photo acoustic trace gas detector (100) is provided for detecting a concentration of a trace gas in a gas mixture. The detector (100) comprises a light source (101) for producing a light beam and a light modulator (103) for modulating the light beam into a series of light pulses at a chopping frequency for generating sound waves in the gas mixture. The amplitude of the sound waves is a measure of the concentration of the trace gas. The detector (100) further comprises an optical cavity (104a, 104b) with the gas mixture. The optical cavity (104a, 104b) amplifies the light intensity of the light pulses. A transducer (109) converts the sound waves into electrical signals. A feed back loop (110, 111, 113, 114) regulates a ratio of a length of the optical cavity (104a, 104b) and a wavelength of the light beam for amplifying the light intensity of the light pulses in the optical cavity (104a, 104b). The feedback loop (110, 111, 113, 114) comprises ratio modulating means (113, 114) for modulating the ratio at a modulation frequency, a photo detector (110) for measuring the light intensity of the light pulses and adjusting means (111), coupled to the photo detector (100) and to the ratio modulating means (113, 114) for, in dependence of the measured light intensity, adjusting an average of the ratio. The chopping frequency is higher than the modulation frequency.]]></description>

            <description><![CDATA[A device for measurement of entrained and dissolved gas has a first module arranged in relation to a process line for providing a first signal containing information about a sensed entrained air/gas in a fluid or process mixture flowing in the process line at a process line pressure. The device features a combination of a bleed line, a second module and a third module. The bleed line is coupled to the process line for bleeding a portion of the fluid or process mixture from the process line at a bleed line pressure that is lower than the process pressure. The second module is arranged in relation to the bleed line, for providing a second signal containing information about a sensed bleed line entrained air/gas in the fluid or process mixture flowing in the bleed line. The third module responds to the first signal and the second signal, for providing a third signal containing information about a dissolved air/gas flowing in the process line based on a difference between the sensed entrained air/gas and the sensed bleed line entrained air/gas.]]></description>

            <description><![CDATA[A dewatering system includes a selective calibrating sensor circuit configured to receive sensor readings from an electronic sensor, to determine if the electronic sensor is immersed in water, and to generate a control output signal accordingly. The selective calibrating sensor circuit periodically performs a self-calibration when the electronic sensor is not immersed in water to cancel the effect of potential contaminants deposited on the electronic sensor over its operating life. The selective calibrating sensor circuit inhibits calibration when the electronic sensor is immersed in water.]]></description>

            <description><![CDATA[A method for sensing an object profile shape involves relatively sweeping (whisking or translating) in angular or translational increments an elongated whisker element having a deflectable cantilever region and an object so that the cantilever region bends as a result of sliding along an object periphery. The moment (torque) at a base region of the whisker element as a result of the bending is determined. The method then iteratively determines successive contact point locations on the object periphery based on small successive increments in angle or position of the whisker element and the sensed moment (torque).]]></description>
