IntroductIon• In case of B io-m ed ical patient m onitoring system , the various physical param eter of patient d escribes the health cond ition of patient.• The continuous patient m onitoring can be achieved by checking the param eters such as:-• RESPIRATIO N RATE• H EART BEAT• BO D Y TEM PERATU RE 2

  12. 12. the lcd dIsplay• L iquid crystal d isplays (L C D s) have m aterials which com bine the properties of both liquid s and crystals. Rather than having a m elting point, they have a tem perature range within which the m olecules are alm ost as m obile as they would be in a liquid , but are grouped together in an ord ered form sim ilar to a crystal.• C onstruction:-An L C D consists of two glass panels, with the liquid crystal m aterial sand witched in between them . 12
  13. 13. crystalonIcs dIsplay C rystalonics d ot – m atrix (alphanum eric) liquid crystal d isplays are available in TN , STN types, with or without backlight. The use of C -M O S L C D controller and d river IC s result in low power consum ption. These m od ules can be interfaced with a 4-bit or 8-bit m icro processor / icro controller. M• The built-in controller IC has the following features:• C orrespond to high speed M PU interface (2M H z)• 80 x 8 bit d isplay RAM (80 C haracters m ax)• 9,920 bit character generator RO M for a total of 240 character fonts. 208 character fonts (5 x 8 d ots) 32 character fonts (5 x 1 0 d ots)• 64 x 8 bit character generator RAM 8 character generator RAM 8 character fonts (5 x 8 d ots) 4 characters fonts (5 x 1 0 d ots)• Program m able d uty cycles• Wid e range of instruction functions d isplay clear, cursor hom e, d isplay on/ off, cursor on/ d isplay character blink, cursor shift, d isplay shift. off,• Autom atic reset circuit, that initializes the controller / d river IC s after power on. 13

  16. 16. gsm modemA GSM modem is a specializedtype of m od em which accepts aSIM card , and operates over asubscription to a m obileoperator, just like a m obilephone. From the m obile operatorperspective, a GSM m od emlooks just like a m obile phone.When a GSM m od em isconnected to a com puter, thisallows the com puter to use theGSM m od em to com m unicateover the m obile network. Whilethese GSM m od em s are m ostfrequently used to provid em obile internet connectivity,m any of them can also be usedfor send ing and receiving SM Sand M M S m essages. 16
  17. 17. gsm networkThe structure of a GSM network:-The network is structured into anum ber of d iscrete sections:•The Base Station Subsystem (the basestations and their controllers).•TheN etwork and Switching Subsystem (the part of the network m ostsim ilar to a fixed network). This issom etim es also just called the corenetwork.•The GPRS C ore N etwork (theoptional part which allows packet based Internet connections).•The O perations support system (O SS)for m aintenance of the network. 17
