There are numerous references on the internet to autonomous sensors.
This article at IEEE Explore defines the term 'autonomous sensor'; it treats it almost as a compound term, and defines it more precisely than one would expect for 'automatic sensor'. In particular, it at least connotes the internal regulation (acquisition and conservation) of power, in addition to having the denotation automatically performing the task/s intended. More an organism analogue than a basic machine: self-regulating rather than just a one-trick pony.
An autonomous sensor is a device that is generally able to perform its
task without being connected to the interrogation unit. Its power
supply is integrated in the device, and very often a harvesting
mechanism is used for its energy production and is able to totally or
partially power the device operation. There has been broad and rapid
evolution in the field of autonomous sensors. Emerging application
fields, the need to increase the life of electronic devices, increased
computational capabilities that require more energy and drastic
reduction in device volume have been drivers of this field. Power
management and wireless connection are becoming major issues in many
applications. Research communities all over the world are working to
find solutions and harvesting methods to optimize the power issue in
sensors with the specific goal of implementing autonomous sensors. We
discuss these concepts and two examples: an autonomous sensing device
and an energy harvester.
is to hit someone with a closed fist, most likely in the face, as in boxing.
to thump
is to make a dull striking sound produced by hitting something
If you punch someone, that could result in knocking out some teeth.
If you thump someone, it is figurative, meaning you hit them somehow to produce a dull sound. 'Thump' is much more commonly understood as a noun, somewhat onomatopoeic, the sound of the word like the sound itself.
To say 'I thumped him and knocked his teeth out' sounds strange because you would not expect a dull sound if teeth were dislodged as a result; you usually don't get a 'thumping' sound from hitting someone in the face hard enough to knock out teeth.
"Final Exam" has a specific meaning as an exam which ends a course and tests all knowledge obtained in that course. It could mean either a final exam for an English course or (less likely, but also possible) a final exam which is written in the English language.
"Final English Exam" doesn't necessarily carry the same connotation, it is simply the last examination of your knowledge of the English language. "The final English exam before we begin the Literature section of this course".
