X-Ray exposure

Objective:

X-Ray exposure counter is widely used in X-Ray machine for counting the number of

cycles used per exposure and also count the number of exposures.

Description:

Generally X-Ray machines will have the mechanical counter, which has been eliminated

now by using the electronic exposure counter, which consists of a micro controller with

seven-segment display, Opto-Coupler and other necessary circuit. This device counts and

displays the present cycles per exposure and also stores the same in the memory present

in the micro controller, which can be retrieved at later stage. There is also a reset button

to erase the previous data if not required and make the way for the new data to be storedas there will be memory space constraint.

The advantages of this device are

It will have the account of previous exposure times and also the number of exposuresdone.

Cost effective. Smaller in size.Highly reliable and accurate.

X-rays are a form of electromagnetic radiation with a wavelength in the range of 10 to

0.1 nanometers, corresponding to frequencies in the range 30 to 3000 PHz. X-rays are

primarily used for diagnostic medical imaging and crystallography. X-rays are a form ofionizing radiation and as such can be dangerous. The various features of X Ray

inspection systems are >> Zoom 2-4-8 times >> Film Safe, does not affect food or

magnetic data >> High and Low penetration features >> Scanned objects are shown in

classified material groups, allowing the operator to precisely identify the contents thevarious uses of X Ray inspection systems are >> customs, narcotics enforcement, or

counter-Think of this situation. You are going to a place where you dont know the

language. If you are traveling in a bus you will find it difficult to find the right place toget down. You always will have to rely on some one else. What if we had a display that

shows the place agents to examine goods or baggage for drugs, weapons, or other

contraband items at contraband in Mailrooms - Corporate offices - Courtrooms - Prisons>>screening of hand baggage, parcels, and boxes etc

ABSTRACT

Glucometers are used for self-monitoring of blood glucose by patients with diabetes. in

the past decade, glucose testing has moved swiftly to the patients bedside in the hospital,

including the operating rooms (OR), Emergency room(ER), and intensive care unit

(ICU), where rapid therapeutic turnaround time is needed. Glucometer have several

advantages compared to conventional laboratory testing. However, the use of

glucometers for management of critically ill patients is controversial.

Glucometers require 1.5 to 14L of whole blood for glucose measurements. The sample

can be arterial, venous, or capillary. Small sample size minimizes blood loss for patients

who need frequent testing.

With wide range of operating temperatures and humidity, glucometer system can be

adapted for use in varying climates, in different geographic location and at various

altitudes, temperatures, and humidity.

Glucometers have short analysis time ranging from 15 to 45 seconds. This allowsphysicians to modify patients treatment promptly where delay in treatment can adversely

affect patient outcomes. This device operates using microcontroller

userfriendly, highly reliable, very compact in size, easy installable)

Descsription:

This is a must have product at every home. Day to day we observe that when we pumpwater from the sump we always forget to switch off the motor and we do it only when

there is an over flow. there are so many water level controllers available in the market but

it fails due to rusting of sensors ,long wiring which requires proper maintainers ,we canthink of an alternate sensor but since it is an low cost device it is tough to implement .as u

know every one is able to switch on the motor but fails at switching off the motor taking

this point we designed non-sensor based device which is designed to automatically

switch off the motor after a certain duration, which can be selected by the user. normallywe know that our tank would take an approximate time to fill completely hence the

device gives the flexibility to set the time depending on the size of the over head tank .tomake the device more user friendly we are providing a preset like fan regulator which isgiven to the adc ,so that when ever the pot rotates it generates the analog out put which

is fed to an 8 bit adc .depending on the digital value the micro controller displays the time

which varies from (0 to 99 minutes ).there is a memory back up under the power failurecondition (eeprom)
