-tron, -tronic, -tronics +
(Greek: a suffix referring to a device, tool, or instrument; more generally, used in the names of any kind of chamber or apparatus used in experiments)
A possible allusion to the Greek instrumental suffix, as in árotron, "plow" as spelled in the U.S. or "plough", as spelled by the British; from the Greek stem aroun, "to plow".
The suffix -tron is the result of the combining form extracted from electron, used with nouns or combining forms, principally in the names of electron tubes (ignitron; klystron; magnetron) and of devices for accelerating subatomic particles (cosmotron; cyclotron); also, more generally, in the names of any kind of chamber or apparatus used in experiments (biotron).
The device may have an alarm in case the flow is restricted because of an occlusion of the line which will result in an alarm that will go off when a preset pressure limit is determined.
Most electronic infusion devices are equipped to stop the flow of the infused liquid if an accidental free-flow occurs.
2. An automated system of introducing a fluid other than blood into a vein.The device may have programmable settings that control the amount of fluid to be infused, rate, low-volume notification level, and a keep-vein-open rate.
Some electronic infusion devices have titration modes that allow a change in the delivery rate without interrupting fluid flow. They also allow delivery in milliliters per hour.
The term titration is the process, operation, or method of determining the concentration of a substance in a solution to which the addition of a reagent having a known concentration is made in carefully measured amounts until a reaction of definite and known proportion is completed, as shown by a color change or by electrical measurement, and then calculating the unknown concentration.
These signals are processed to give the nature and deployment of enemy warning and missile guidance radars, fire control, and countermeasures systems.
3. Electronic systems, apparatus, and operations for obtaining information concerning a military enemy's capabilities, intentions, plans, and order of battle.
2. Any electrical or electromagnetic disturbance that causes undesirable responses in electronic equipment.
3. An electric or electromagnetic disturbance which causes undesirable responses in electronic equipment.
Electric interference refers specifically to an interference that is caused by the operation of an electric apparatus which is not designed to radiate electromagnetic energy.
2. Radiation or re-radiation of electromagnetic waves so as to impair the usefulness of a specific segment of the radio spectrum that is being used by a military enemy for communication or radar.
3. To interfere with or to prevent the clear reception of (broadcast signals) by electronic methods.
2. In facsimile copying, a method by which a spot on a cathode-ray tube moves across the copy by electronic actions.
3. A method that provides motion of the scanning spot along the scanning line controlled by electronic procedures.
4. Facsimile scanning in which a spot on a cathode-ray tube moves across the copy electronically while the record sheet or subject copy is moved mechanically in a perpendicular direction.
2. A device used to capture the sound waves of conversations originating in an supposedly private setting in a form, usually as a magnetic tape recording, which can be used against the target by anyone with negative intentions.
2. A portable electronic device with a search head that is swept over the ground and used to detect buried metal objects such as coins.
3. An electronic device that registers the presence of metal; used, for example, to detect metal weapons or to screen passengers at an airport.
4. An electronic tool used in the food industry to check for the presence of pieces of metal that might have accidentally gotten into food during the processing activities.
2. A technique for preventing the operation of a switch until a specific electrical signal (the unlocking signal) is introduced into circuitry associated with the switch.
Usually, but not necessarily, the unlocking signal is a binary sequence.
2. The magnetic dipole moment which an electron possesses by virtue of its spin.
3. The total magnetic dipole moment associated with the orbital motion of all the electrons of an atom and the electron spins.
This is opposed to a nuclear magnetic moment.
2. The electronic transmission of letters, messages, and memos via a communications network; now more often via computer connections.
3. A system for sending messages by computer, Telex, facsimile telegraph, or other electronic means instead of by post.
4. Messages sent by one user of a computerized communications system and retrieved almost instantly by other users.
The messages may be transmitted with a modem through telephone lines or, in some cases, by shortwave radio and it can be in many forms, including mailgrams, twx, and facsimile transmission devices.
2. Microradiography of very thin specimens in which the emission of electrons from an irradiated object, either the specimen or a lead screen behind it, is used to produce a photographic image of the specimen, which is then enlarged.
Microradiography is a technique for the study of surfaces of solids by monochromatic-radiation (such as X-ray) contrast effects shown by means of projection or enlargement of a contact radiograph.
2. A control circuit used to change or to vary the speed of a direct-current (DC) motor operated from an alternating-current (AC) power line.
Silicon controlled rectifiers or power transistors rectify or correct the voltage and vary the field current of the motor.
2. A multimeter that uses semiconductor or electron-tube circuits to drive a conventional multiple-scale meter.
3. An apparatus that employs the characteristics of an electron-tube circuit for the measurement of electrical quantities, at least one of which is voltage or current, or a single calibrated scale.
When a digital display replaces the moving-coil meter, it is called a "digital multimeter".
2. A musical device that generates sounds electronically.
A cross reference of word units that are related, directly and/or indirectly, with "electricity": electro-; galvano-; hodo-; ion-; piezo-; volt; biomechatronics, info; mechatronics, info.
