CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the benefit of United Kingdom Patent Application No. 1200530.2, filed Jan. 12, 2012, published as GB2485690 on May 23, 2012. 
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a monitoring system for sudden infant death syndrome alerts parents, including parents who are blind and deaf, of any unexpected and unpleasant change in their infant&#39;s health condition, especially at night time. 
     2. Description of the Related Art 
     Every year thousands of babies die of premature crib death, also known as Sudden Infant Death Syndrome. While some of them inherited some problems such as heart irregularities or respiratory distress, other deaths are caused by accidents such as suffocation from blankets or pillows and lack of attention to certain readily observable conditions such as body temperature due to illness. In almost all cases, early detection can save the infants from death. Even though the probability of such tragedies happening is relatively small, most parents and caretakers are eager to acquire a device that will help them to further minimize the chance of suffocation if the device is inexpensive and easy to use. 
     There are some relevant documents to monitoring sudden infant death syndrome of infants. For example the GB patent GB2447237 which describes a baby heartbeat monitoring device to prevent cot death comprises a wrist band  4  to be attached to the baby&#39;s wrist, an electrode sensor  3  to measure pulse rate, and a lithium battery  2 . If a change in heartbeat is detected the wristband wirelessly transmits an alarm signal to a remote receiver device  8  where an audible alarm is sounded. 
     Further the GB patent GB2442537 which describes The Wireless Skin Temperature monitoring device consists of two devices. The first device is an adjustable waterproof silicone arm band  3 , worn on a baby&#39;s upper-arm, housing a temperature sensor  1 , microprocessor, RF transmitter and power source  5  which will send the temperature data to the other device. Popper fixings  2 ,  4  are used to secure the band around the arm. The second device is a receiver device  7 , also made from silicone  6  and worn on the wrist of a carrier or parent, housing an RF Receiver, microprocessor, power source and LCD Module  7  displaying the temperature reading or digital time. When pre-defined temperatures are reached an alarm will sound and the LCD will change color, blue for cold, and red for hot. If extreme temperatures are reached the LCD display will flash the respective color and will sound a louder more rapid alarm. The LCD will also display a wireless signal strength indicator and display the time. A wireless on/off reset button  8  is featured to switch off any alarm. A Time set button  9  is featured to set hour and minutes on the receiving device. 
     In addition, the GB patent GB2346217 describes a detection device capable of being coupled to a person for remotely monitoring heart and respiratory functions includes a processor, a photo cell coupled to the processor for determining blood oxygen content of the person and a temperature sensor coupled to the processor for determining a temperature of the person. The processor compares the determined blood oxygen content and the temperature to desired values. A transmitter is included for transmitting a warning signal if one of the determined blood oxygen content and the temperature are other than the desired values. The device is battery powered and transmits signals at radio frequencies. The warning may be visual or audible. 
     Therefore, a need exists for providing a system for early warning to allow quick response to signs of suffocation in infants or other people who are unable to help themselves. Such a system could save thousands of lives every year. A further need exists for early detection of progressing illness which may relieve parents or caretakers some of the stress and effort in monitoring people under their care.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The invention describes a monitoring system for sudden infant death syndrome for blind and deaf parents comprises portable warning and monitoring control unit and electronic bracelets. 
     As Shown in FIGS.  1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9  the warning and monitoring control unit for Sudden Infant Death Syndrome alert parents (include those parents who are blind and death) on any unexpected and unpleasant change in their infant health condition, especially at night time, and consist of three parts. 
     As shown in  FIGS. 1&amp;2  the first part is the portable warning and monitoring control unit that has an antenna ( 31 ), a power switch ( 2 ) that can be pressed in to switch “on” portable warning and monitoring control unit ( 1 ), and release out to switch “off” the portable warning and monitoring control unit, four speakers ( 3 , 4 , 5 , 6 ) each speaker has its unique and different tones that alert the parents through a sound alarm when either infant heart beating rate ( 7 ), temperature reading ( 8 ), blood pressure reading ( 9 ), and oxygen saturation ( 10 ) level falls below or exceeds the normal reading. The four speakers are contacted to a sound control switch ( 11 ) to lower or increase the sound (good for those parents who have hearing problems). The portable warning and monitoring control unit has also four separate buttons ( 12 , 13 , 14 , 15 ). When pressed the first button ( 12 ) parents would hear a voice stating the exact reading for infant heart beating. When pressed the second button ( 13 ) parents would hear the exact reading for infant temperature. When the third button is pressed ( 14 ) parent would hear the exact reading for infant blood pressure. When pressed the fourth button ( 15 ) parents would hear the exact reading for infant oxygen saturation. This would enable parents, especially who are blind parents, to monitor their infant health conditions. 
     The portable warning and monitoring control unit has also a horizontal hard plastic coat cover the front top side of the portable warning monitoring control unit ( 16 ) to protect the screens and reading cells from being damaged when the unit accidentally falling face down on a hard floor. The portable warning and monitoring control unit has also four screens ( 17 , 18 , 19 , 20 ). The first screen shows infant heart beating rate ( 17 ), with green light ( 21 ) to indicate that measuring infant heart beating reading is in progress, warning red light ( 22 ) to indicate “very low” or “exceed” in infant heart beating reading. Numerical reading and Braille numbers/codes for infant heart beating rate level located above the first screen ( 7 ,  23 ). An abbreviation of heart beating (HP) is printed in a Braille letters/characters above the first screen ( 24 ). This would help blind and death parents to identify the first screen as for infant heart beating. A Braille letters/characters is designed for those parents who are blind and death. 
     The second screen shows infant temperature level ( 18 ), with green light ( 25 ) to indicate that measuring infant temperature level is in progress, warning red light ( 26 ) to indicate “very low” or “high” in infant temperature level. Numerical reading and Braille numbers/codes for infant temperature level ( 8 ,  27 ) located above the second screen ( 28 ). An abbreviation of infant temperature (T) is printed in a Braille letters/characters above the second screen. This would help blind and death parents to identify the first screen as for infant temperature. The third screen shows infant blood pressure level ( 19 ), with green light ( 29 ) to indicate that infant measuring air pressure level is in progress, warning red light ( 30 ) to indicate any “very low” or high” in infant blood pressure level. Numerical reading and Braille numbers/codes for infant blood pressure level ( 9 ,  31 ) located above the third screen. An abbreviation of infant blood pressure (BP) is printed in a Braille letters/characters above the third screen ( 32 ). This would help blind and death parents to identify the first screen as for infant blood pressure. The fourth screen shows infant oxygen saturation level ( 20 ), with green light ( 33 ) to indicate that infant measuring oxygen saturation level is in progress, warning red light ( 34 ) to indicate any “very low” or high” in infant oxygen saturation level. Numerical reading and Braille numbers/codes for infant oxygen saturation level ( 10 , 35 ) located above the fourth screen ( 36 ). An abbreviation of infant oxygen saturation (OS) is printed in a Braille letters/characters above the fourth screen. This would help blind and death parents to identify the first screen as for infant oxygen saturation. 
     The portable warning and monitoring control unit has also processing control unit has processor to collect data and compare it with the default values (not shown in the figures), and memory to store reading data from the three sensors (not shown in the drawings). The portable warning and monitoring control unit has also a speaker ( 37 ) receive infant voice and unusual infant movements from the sensitive microphone build into the infant bracelet. The portable warning and monitoring control unit speaker has also a switch ( 38 ) that can be pressed in to switch on&#39; the speaker and release out to switch off the speaker. The portable warning and monitoring control unit has also a hanger ( 39 ) that allow parent to monitor infant health condition throughout the house, rechargeable battery case ( 40 ) electricity connection ( 41 ). 
     As Shown in  FIG. 3 , the second part is the electronic bracelet made of elastic waterproof material that would be placed around the infant arm ( FIG. 6 ). The electronic bracelet consists of heart beating sensor ( 42 ), temperature sensor ( 43 ), blood pressure sensor ( 44 ), oxygen saturation sensor ( 45 ) supported rechargeable battery ( 46 ), processing unit to collect data from the four sensors (not shown in the drawing), and transceiver to receive and transmit data between the bracelet processing unit and the main portable control monitoring unit (not shown in the drawing). The four sensors in the bracelet can be activated by pressing the concern sensor ( FIG. 4 , No.  43 ), and deactivated when releasing the same sensor. 
     The bracelet has also a sensitive microphone ( FIG. 3 , No.  47 ) which would detect infant voice and infant unusual movements and then transfer infant voice and infant unusual movements to the speaker already build into the portable warning and monitoring control unit ( FIG. 1 , no.  37 ). This would allow the parents to hear their infant voice and unusual movements from distance. 
     To operate monitoring system for sudden infant death syndrome, the portable warning and monitoring control unit has to be switched “on” by pressing the switch in the control panel ( FIG. 1 , No.  2 ), automatically green lights for heart beating reading indicator ( FIG. 1 , No.  21 ), temperature reading indicator ( FIG. 1 , No.  25 ), blood pressure indicator ( FIG. 1  No.  29 ), and oxygen saturation indicator ( FIG. 1 , No.  33 ) would all be appear. This indicates that the control panel ( FIG. 1 , No.  1 ) is ready to receive information, through the antenna ( FIG. 1 , No.  31 ) from the bracelet that is attached around the infant arm ( FIG. 8 ). On the other hand, the four sensors in the bracelet can be activated by pressing the concern sensor ( FIG. 4 , No.  43 ), and deactivated when releasing the same sensor. In other word, when infant temperature sensor is pressed for example at the bracelet the infant temperature sensor would light to indicate that is activated “on” ( FIG. 4 , No.  43 ). However, when releasing the same sensor (infant temperature sensor) the light would disappear to indicate that the temperature sensor is deactivating “off”. The first information the bracelet would send is infant heart beating condition ( FIG. 3 , No.  42 ). The second information the bracelet would send is infant temperature condition ( FIG. 3 , No.  43 ). The third information the bracelet would send is infant blood pressure condition ( FIG. 3 , No.  44 ). The fourth information the bracelet would send is infant oxygen saturation condition ( FIG. 3 ,  45 ). The control panel would then display the level of infant heart beating ( FIG. 1 , No.  17 ) with numerical and a Braille numbers/codes for infant heart beating reading ( FIG. 1 , No.  7 ,  23 ), infant temperature level ( FIG. 1 , No.  18 ), with numerical and a Braille numbers/codes for infant temperature reading ( FIG. 1 , No.  8 ,  27 ), infant blood pressure level ( FIG. 1 , No.  19 ), with numerical and a Braille numbers/codes for infant blood pressure reading ( FIG. 1 , No.  9 ,  31 ), and infant oxygen saturation reading ( FIG. 1 , No.  20 ), with numerical and a Braille numbers/codes for infant oxygen saturation reading ( FIG. 1 , No,  10 ,  35 ). 
     In the case when infant heart beating reading falls “below” or exceeds” the normal reading (100-130), a red light would appear ( FIG. 1 , No.  22 ) companies with a sound warning ( FIG. 1 , No.  3 ) to alert the parents of such unpleasant change in their infant heart beating reading. In the case when infant temperature reading falls “below” or exceeds” the normal reading (37 cent grate), a red light would appear ( FIG. 1 , No.  26 ) companies with a sound warning ( FIG. 1 , No.  4 ) to alert the parents of such unpleasant change in their infant temperature reading. In the case when infant blood pressure reading falls “below” or exceeds” the normal reading (70-8 5), a red light would appear ( FIG. 1 , No.  30 ) companies with a sound warning ( FIG. 1 , No.  5 ) to alert the parents of such unpleasant change in their infant blood pressure reading. In the case when infant oxygen saturation reading falls “below” or exceeds” the normal reading (96-97), a red light would appear ( FIG. 1 , No.  34 ) companies with a sound warning ( FIG. 1 , No.  6 ) to alert the parents of such unpleasant change in their infant oxygen saturation reading. 
     As Shown in  FIG. 5 , the third part is the electronic bracelet made of elastic waterproof material put around the wriest of the blind and death parents (FIG.  5 , 6 ). The electronic bracelet consists of heart beating vibrated device ( 48 ), temperature vibrated device ( 49 ), blood pressure vibrated device ( 50 ), oxygen saturation vibrated device ( 51 ) supported by rechargeable battery ( 52 ), processing unit to collect data from the four sensors (not shown in the drawing), and transceiver to receive and transmit data between the bracelet processing unit and the main portable control monitoring unit (not shown in the drawing). Each of the four vibrated devices is identified by using an abbreviation letter using a Braille characters printed on the top of each device for identification. For example, printed the letters (MB) on the top of the first vibrated device, using a Braille characters, to indicate that this vibrated device for infant heat beating ( FIG. 5 , No.  53 ). Printed letter (T) on the top of the second vibrated device, using Braille characters, to indicate that this vibrated device is for infant temperature level ( FIG. 5 , No.  54 ), printed letters (BP) on the top of the third vibrated device, using a Braille characters, to indicate that this device is for infant blood pressure ( FIG. 5 , No.  55 ), printed letters (ox) on the top of the fourth vibrated device, using a Braille characters, to indicate that this device is for infant oxygen saturation ( FIG. 5 , No.  56 . All abbreviations letters are printed in the Braille characters/letters which are designed for those parents who are blind and death. 
     In the case when infant heart beating reading falls “below” or exceeds” the normal reading (100-130), the device marked with the letter (FIB) would vibrate to alert the parents, especially while parents are sleeping, to take the right action ( FIG. 6 , No.  48 ). In the case when infant temperature reading falls “below” or exceeds” the normal reading (37 cent grate), the device marked with the letter (T) would vibrate to alert the parents, especially while parents are sleeping, to take the right action ( FIG. 6 , No.  49 ). In the case when infant blood pressure reading falls “below” or exceeds” the normal reading (70-85), the device marked with the letter (BP) would vibrate to alert the parents, especially while parents are sleeping, to take the right action ( FIG. 6 , No.  50 ). In the case when infant oxygen saturation reading falls “below” or exceeds” the normal reading (96-97), the device marked with the letter (ox) would vibrate to alert the parents, especially while parents are sleeping, to take the right action ( FIG. 6 , No.  51 ). 
     The bracelet which is designed for parent who are blind and death has also a switch with three indicators marked  1 ,  2  and  3  ( FIG. 6 , No.  57 ) to control the volume of vibration. For example No. (I) on the switch means less vibration, no ( 2 ) on the switch means medium vibration, and No. ( 3 ) on the switch means high vibration. 
     The Features of the design for which novelty is claimed reside in the shape &amp; configuration of the article as shown in the representations.
