Q

what amplifies electrical signals?

23
Q

How can sensors be converted?

A

chemical concentration, temperature, pressure, or flow into electrical signals that can be further processed.

24
Q

Interfacing to the human body, sensors must be what?

A

biocompatible, flexible, and extremely robust to survive in the aggressive internal environment, while surface sensors, particularly electrodes, must be able to form a compatible and relatively stable conductive interface across the skin

25
Signal processing involves what?
modification of the electrical signal to some form that is more useful.
26
modification of the electrical signal involves what?
amplification and filtering to extract salient features and the conversion of the analog signal to a digital equivalent that allows for the application of complex algorithms to obtain subtler characteristics
27
In many cases, the biomechatronic device functions to monitor what?
a physiological process or response
28
it may be important to display what, when monitoring a physiological process or response
the information in a form that is easy to interpret, or to store it for later analysis.
29
What are examples of monitoring systems?
the 12- lead electrocardiograph, pneumotachographs and sphygmomanometers.
30
In a closed-loop control application, any stimulus or excitation signal is conditioned by what?
the processed outputs of one or a number of sensors monitoring the physiological process.
31
what includes further processing through control elements?
The link that connects the sensing output back to the stimulus
32
This feedback can be used to close what?
an external loop or one that operates through the human being.
33
When and Who was OS developed?
1969 by Bell Labs in conjunction with M.I.T.
34
What is Unix commonly used for?
Universities and Academia
35
Who started using UNIX?
Graduates began using UNIX at their jobs
36
What was Microsoft DOS designed for?
Designed to be an operating system that could run on any 8086-family computer
37
What occurred in the 1980s?
Microsoft DOS was main operating system for personal computers
38
What does CLI stand for?
Command line interface
39
When do you use rm command?
delete files
40
Can you retrieve files again after using rm?
no
41
What should you use carefully when deleting files?
use wildcards carefully
42
What is scripting language?
or script language is a programming language that supports scripts, programs written for a special run-time environment that can interpret (rather than compile) and automate the execution of tasks which could alternatively be executed one-by-one by a human operator.
43
When do you use triple double-quotes?
for multi-line strings or strings than contain both ‘ and “ inside of them
44
What is meaningful in Python?
Whitespace especially indentation and placement of newlines
45
When do you Use a newline?
to end a line of code
46
When do you Use \?
when must go to next line prematurely
47
What is not used to mark blocks of code in Python?
No braces { }
48
The first line with less indentation is where?
outside of the block
49
The first line with more indentation starts what?
a nested block
50
what appears at the start of a new block?
a colon
51

– the rest of line is ignored
52
Can you include a “documentation string” as the first line of any new function or class that you define.
yes
53
