  2. Bracewell probe - Wikipedia

    en.wikipedia.org/wiki/Bracewell_probe

    A Bracewell probe is defined as an autonomous robotic interstellar space probe with advanced AI, pre-loaded with information or data its creators wish to convey.It would seek out existing technological civilizations or monitor worlds where such civilizations are likely to arise, establishing contact, making its presence known, conducting a dialogue over short distances (compared to ...

    en.wikipedia.org/wiki/Self-replicating_spacecraft

    Probe: which would contain the actual probing instruments & goal-directed AI to guide the construct. Life-support systems: mechanisms to repair and maintain the construct. Factory: mechanisms to harvest resources & replicate itself. Memory banks: store programs for all its components & information gained by the probe. Engine: motor to move the ...

  4. Nanoprobing - Wikipedia

    en.wikipedia.org/wiki/Nanoprobing

    Existing nanoprobe needles or “probe tips” have a typical end-point radius ranging from 5 to 35 nm. [2] The fine tips enable access to individual contacts nodes of modern IC transistors. Navigation of the probe tips in SEM based nanoprobers are typically controlled by precision piezoelectric manipulators. Typical systems have anywhere from ...

  5. Electron microprobe - Wikipedia

    en.wikipedia.org/wiki/Electron_microprobe

    The electron microprobe (electron probe microanalyzer) developed from two technologies: electron microscopy — using a focused high energy electron beam to impact a target material, and X-ray spectroscopy — identification of the photons scattered from the electron beam impact, with the energy/wavelength of the photons characteristic of the atoms excited by the incident electrons.

  6. Oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Oxygen_sensor

    An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analyzed. [1] It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter Bauman. [1]

  7. Flying probe - Wikipedia

    en.wikipedia.org/wiki/Flying_probe

    One limitation in flying probe test methods is the speed at which measurements can be taken; the probes must be moved to each new test site on the board, and then a measurement must be completed. Bed-of-nails testers touch each test point simultaneously and electronic switching of instruments between test pins is more rapid than movement of probes.

  8. Logic probe - Wikipedia

    en.wikipedia.org/wiki/Logic_probe

    A logic probe is a low-cost hand-held test probe used for analyzing and troubleshooting the logical states (boolean 0 or 1) of a digital circuit. When many signals need to be observed or recorded simultaneously, a logic analyzer is used instead.

  9. PROBA-3 - Wikipedia

    en.wikipedia.org/wiki/Proba-3

    PROBA-3 is a dual-probe technological demonstration mission by the European Space Agency devoted to high-precision formation flying to achieve scientific coronagraphy.It is part of the series of PROBA satellites that are being used to validate new spacecraft technologies and concepts while also carrying scientific instruments.
