A method for detecting an operational condition of a multi-conductor cable is described, and which includes generating a first, single ended, time domain reflectometer signal which is introduced into a multi-conductor cable; processing the first, single ended, time domain reflectometer signal so as to generate a first, differential time domain reflectometer signal; supplying the first, differential time domain reflectometer signal to the multi-conductor cable; converting a reflected, differential time domain reflectometer signal into a second, single ended, time domain reflectometer signal; numerically and/or graphically analyzing the second, single ended, time domain reflectometer signal; and identifying, by the numerical and/or graphical analysis, an operational condition of the multi-conductor cable undergoing the testing.

Probe for indentifying and measuring volume fraction constituents of a fluid

An improved fruit tester and method provides a plunger intrusion-type mechanism, a precision scale and an associated computer for control of the mechanism and for recordation, presentation and analysis of data sensed by the mechanism. An electrically powered variable speed motor carries an optical encoder to sense rotary direction and speed data, which is transmitted through circuitry to an associated computer for analysis to determine control data to maintain pre-programmed motor function. Computer software determines plunger position and resultant penetration into a fruit at either pre-determined plunger speed or constant plunger resistive pressure in fine increments over the plunger trajectory and stores this data in computer memory. The precision scale is used to determine the weight of the fruit before and after the penetration tests and the difference in weight is used to automatically calculate the Specific juice Content (SJC) of the fruit.

Automated machine and method for fruit testing

A fruit tester provides a motor driven intrusive plunger with associated sensors to determine digital data indicative of plunger position, force resisting plunger intrusion and constant pressure creep. Sensor data is presented to a computer for storage, analysis and feedback control of the plunger. The plunger powering train includes a belt driven ball screw translator to convert rotary to linear motion and an &ldquo;S&rdquo; type stress block with plural bridge interconnected strain gauges to sense pressure resisting intrusion to allow accurate measurements. Methods of analysis are disclosed to determine both resistance to plunger penetration and plunger creep at fixed pressure, in each of at least two concentric zones of a fruit, which are related by software for accurate determination of fruit condition as a function of time, both present and future.

A sensor system for use with time domain reflectometry systems to allow measurement of relative proportions of intermixed constituents having differing electrical permittivities contained in a fluid mixture. The sensor has at least one primary electrode and one secondary electrode which are spaced apart across a flow channel. One electrode is connected to a first conductor carrying the active time domain reflectometry signal pulse. The other electrode is connected to the passive or ground conductor which carries any reactive signal resulting from the active signal. A fluid mixture of variable proportions will demonstrate a variable dielectric constant which affects the reflected signals sensed by the time domain reflectometer.

A sensor for use with time domain reflectometry systems to allow measurement of relative proportions of intermixed constituents having differing electrical permittivities contained in a fluid mixture. The sensor comprises a central primary electrode and a pair of adjacent outer secondary outer electrodes. The fluid mixture is located between the electrodes during sensing. A dielectric layer covers exposed sensing surfaces of the electrodes to electrically isolate the electrodes from the fluid mixture and to prevent dissipation of a time domain reflectometry signal propagated through the sensor.

Mixed fluid time domain reflectometry sensors

Methods and apparatus for determining the relative proportions of intermixed constituents of a multiphase fluid system. The constituents for which relative proportions are being measured must have measurably different electrical permittivities. The systems use at least one electrically conductive probe having two conductors which are spaced apart and capable of receiving the fluid system therebetween. Time domain reflectometers present a stimulating time varying electrical signal to the probes and receive and measure reflected signals generated at impedance changes in the transmission line and probe. The probe transit time and/or associated average probe velocity provide a measure of the fluid system conditions which can be compared to predetermined values corresponding to various relative proportions of the intermixed constituents. A measure of the relative portions of the constituents is thus provided. The variability of individual probe transit velocity data can be measured, analyzed and used to measure fluid system turbulence. Relevant data can also be interpolated, extrapolated and integrated to provide profiling of the fluid system conditions and a means of total system inventory of the constituents.
