Insulin Pump for Diabetes Mellitushttp://www.medicinenet.com/insulin_pump_for_diabe

tes_mellitus/article.htm

What is an insulin pump?

The most recentl available advance in insulin deliver is

the insulin pump.In the United States, MiniMed and Disetronic market the

insulin pump.An insulin pump is composed ofv a pump reservoir similar to that of an insulin cartridge,v

a battery-operated pump,v and a computer chip that allows the user to controlthe exact amount of insulin being delivered.

Insulin Pump for Diabetes MellitusHow does an insulin pump work?The pump is attached to a thin plastic tube (an infusion set) that has

a soft cannula (or plastic needle) at the end through which insulinpasses. This cannula is inserted under the skin, usually on theabdomen.

The cannula is changed every two days.The tubing can be disconnected from the pump while showering or

swimming.The pump is used for continuous insulin delivery, 24 hours a day.The amount of insulin is programmed and is administered at a

constant rate (basal rate). Often, the amount of insulin neededover the course of 24 hours varies depending on factors likeexercise, activity level, and sleep.

The insulin pump allows the user to program many different basalrates to allow for variation in lifestyle.In addition, the user can program the pump to deliver a bolus (large

dose of insulin) during meals to cover the excess demands ofcarbohydrate ingestion.

Control Application #4Active noise control (ANC)

http://en.wikipedia.org/wiki/Active_noise_control

Active noise control (ANC), also known as noise cancellation,

or active noise reduction (ANR), is a method for reducingunwanted sound.

Control Application #4 (continued)Active noise control (ANC)

http://www.analog.com/en/content/silentium_blackfin_active_noise_cancellation/fca.html

In an electronics-populated world where ambient noises abound,Silentium's active noise control (ANC) products promise "Silence in a chip",and in this case, the chip is an Analog Devices' Blackfin processor.With the help of powerful digital signal processing from Analog Devices,Silentium has successfully taken on the technological challengeof creating true silence amidst the constant hum and annoyance of electronic equipment.Delivering more than 10dB (A) broadband noise reduction across the entire audible spectrum,Silentium's ANC solutions, based on their S-Cube Controller technology,are a result of the company's extensive research and development in acoustics field analysis.Active noise cancellation is in demand for a full range of applications and industries,including server and networking equipment, air treatment, air conditioning machinery,automotive and aircraft cabins, white goods, and more.By utilizing the powerful Blackfin BF533 digital signal processor within their low cost,

portable design, Silentium enables product developers to easily incorporate ANC functionality..

Control Application #5Active vibration control

http://en.wikipedia.org/wiki/Active_vibration_control

Active vibration control is the active application of force in anequal and opposite fashion to the forces imposed by externalvibration. With this application, a precision industrial process canbe maintained on a platform essentially vibration-free.

machinery is being affected by vibration. For example, theproduction of semiconductor wafers requires that the machinesused for the photolithography steps be used in an essentiallyvibration-free environment or the sub-micrometre features will beblurred. Active vibration control is now also commercially availablefor reducing vibration in helicopters, offering better comfort withless weight than traditional passive technologies.

In the past, passive techniques were used. These includetraditional vibration dampers, shock absorbers, and base isolation.

Control Application #5 (continued)Active vibration control

http://www.barrycontrols.com/engineering/active_systems.cfm

Active vibration control systems control vibration

by electronically sensing the disturbance

and taking an action to compensate for it.

Most active vibration control systems are hybrid systems

using active control for low frequencies

and passive isolation for higher frequencies.

They offer superior performance compared to passive systems

by providing better low frequency isolation,

without the high static deflections associated with passive devices,

and improved settling times.

Active actuators can be hydraulic, pneumatic,piezoelectric and other styles.

Control Application #7PLL Phase-locked loop

http://en.wikipedia.org/wiki/Phase-locked_loop

A phase-locked loop or phase lock loop (PLL) is a control system thatgenerates an output signal whose phase is related to the phase of aninput signal.

While there are several differing types, it is easy to initially visualize as anelectronic circuit consisting of a variable frequency oscillator and a phase

. The oscillator generates a periodic signal. The phase detector compares

the phase of that signal with the phase of the input periodic signal andadjusts the oscillator to keep the phases matched.

Keeping the input and output phase in lock step also implies keeping theinput and output frequencies the same.

Consequently, in addition to synchronizing signals, a phase-locked loopcan track an input frequency.

These properties are used for computer clock synchronization,demodulation, and frequency synthesis, respectively. Phase-locked loops are widely employed in radio, telecommunications,

computers and other electronic applications.

Control Application #7 (continued)PLL from ALTERA

http://www.altera.com/support/devices/pll_clock/basics/pll-basics.html

A phase-locked loop (PLL) is a closed-loop frequency-control system basedon the phase difference between the input clock signal and the feedbackclock signal of a controlled oscillator. The main blocks of the PLL are thephase frequency detector (PFD), charge pump, loop filter, voltage controlledoscillator (VCO), and counters, such as a feedback counter (M), a pre-scalecounter (N), and post-scale counters(C).


21/24

Control Application #7 (continued)PLL with Matlab/Simulink

http://www.mathworks.com/matlabcentral/fileexchange/14868-phase-locked-loop-tutorial/content/html/plldemo.html

A phase-locked loop (PLL) is a closed-loop feedback control system thatgenerates and outputs a signal in relation to the frequency and phase of aninput ("reference") signal. A phase-locked loop circuit responds to both thefrequency and the phase of the input signals, automatically raising or loweringthe frequency of a controlled oscillator until it is matched to the reference inboth frequency and phase.

This type of mechanism is widely used in radio, telecommunications, computers

signal or to detect signals in the presence of noise.
