  International Test Solutions - Probe Card Cleaning Technology
Probe Clean™ is a unique highly cross-linked polymeric probe needle cleaning material that is non-conductive, non-corrosive material that removes and traps the loose debris that accumulates on the probe tips and shaft.
Probe Polish™ combines the attractive forces of Probe Clean™ with uniformly and spatially distributed abrasive particles for the added benefit of removing embedded contaminants during probe needle cleaning.
Probe Scrub™ is a multilayer probe card cleaning medium developed for collecting particulates and debris that accumulate on probes during wafer sort and effectively removing "weld nuggets" from the probe tip contact surface.

 Use of PH Probe Testing in Diagnosing Asthma - National Jewish Medical and Research Center
A pH probe will help identify if you have increased amounts of reflux and if it is causing you to have trouble breathing or other symptoms.
Once the pH probe is placed tape will be placed around the tube and on the nose to keep the probe in place.
Tests used to manage asthma may include a barium swallow study.

 A2 Flying Probe Test Systems
Test point densities on printed circuit boards and other interconnect substrates increase steadily and unrelentingly as do reductions in pad sizes and spacing.
A test methodology containing throughput, high technology testability, dependability, and a superior economic model is realized by this series of flying probe test systems.
Significantly reduced test times are realized as eight, twelve, or sixteen probes work independently of each other in small zones with little mechanical motion and at great overall speed.

 Parallel Test Reduces Costs At Wafer Probe
Testing in parallel is commonly used to increase test throughput and reduce costs.
Massively parallel probing poses several key requirements for the tester, prober, and wafer interface: a significant systems-engineering problem that must be solved through mutual cooperation among the customer, both the tester and the prober vendors, and the wafer interface manufacturer.
This means that the probe card, probe-card holder, and prober chuck must be robust enough to hold the wafer and probes parallel to within a few microns as the probe card moves across the wafer and the temperature of the probing environment varies.

 Windsor HP Probe - ASTM C-803
The Windsor HP Probe system rapidly and accurately determines the concrete compressive strength of a structure by driving a probe into the concrete with a known amount of force.
The probes are made of a high strength alloy, specially heat treated and annealed to achieve a hardness of Rockwell C 48.Special machining of each probe eliminates stress concentrations.
The probes measure the strength of the actual concrete in a structure rather than that of a sample compacted and cured under strict and somewhat artificial conditions which do not necessarily represent those of the structure itself.

 Sypris Test & Measurement | Probe Selection Tips
Before selecting a probe it is important to know the direction of the magnetic lines of flux (choose between axial or transverse), the measurement environment, and any limiting physical constraint.
Axial probes read lines of magnetic flux through the length of the probe, while transverse probe read lines of flux moving perpendicularly (at right angles) through the tip.
Probe Length: allows the flexibility to shorten or lengthen the stem of the probe.

The Probe was released from the gondola at 11.09 a.m.
Additional helicopter drop tests were therefore conducted and their results demonstrated that this undamped motion was not due to an interaction between the descent module's wake and the stabiliser chute.
Further analysis of the wind conditions during the original drop test revealed that during the descent through the lower stratosphere and troposphere the wind had reached speeds of 50 m/s and there was a high wind gradient.

 Test Probe Frequency Compensation
This capacitor matches the capacity of the probe and connecting cable to the input of the oscilloscope for flat frequency response.
The ground connection should be made as close to the test point as possible because the extra inductance of a printed circuit board or chassis wiring will have the same effect on the displayed signal as the longer ground leads-waveform distortion.
By attaching the oscilloscope test probe to point A in the circuit, you can compare the CRT display to the waveform shown in view A. You can troubleshoot the entire circuit by comparing the waveforms at test points A, B, C, and D with that of your scope.

 USATODAY.com - Condit passes lie test; police probe 4 theories   (Site not responding. Last check: 2007-10-23)
WASHINGTON (AP) — Rep. Gary Condit took a lie-detector test arranged by his lawyer and it showed he "was not deceptive in any way" in denying knowledge of what happened to missing intern Chandra Levy, the lawyer said Friday.
Police dismissed the test as "self-serving." With Condit's relationship with Levy and other women under intense media scrutiny, lawyer Abbe Lowell said that his client had cooperated fully and that police and the press should turn their attention elsewhere.
Lowell said the test was administered by Barry D. Colvert, a polygraph expert who Lowell said teaches FBI officials how to administer the tests and has been used by the government in a number of high-profile espionage cases.

Machesky said he filed an educator misconduct complaint form with state education officials after a determination that the test, "in our opinion, was inappropriately administered." The complaint form stemmed from an investigation done by Tom Colebank, assistant to the superintendent, and William Dickinson, the school principal, the superintendent said.
The superintendent said the investigation showed that a multiple-choice section of the reading test was filled in for some of the eighth-grade pupils who took it.
Past problems with the test most often concerned a test being given at a time other than that set by state officials, she said.
