Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a medical and tracking device, and particularly to a wrist-mounted device to assist pilgrims, especially pilgrims who come to Mecca (Makkah) to make the Hajj and Umrah pilgrimages. 
         [0003]    2. Description of the Related Art 
         [0004]    The most important concern for an Islamic individual in the performance of religious rituals, such as Hajj and Umrah during Ramadan and Hajj holy days, is to adhere to the rituals as prescribed in the individual&#39;s religious community. Some rituals require the individual or pilgrim to circle a holy site (e.g., the Kaaba or Ka&#39;aba, the most sacred site in Islam, the circling being part of a ritual known as the Tawaf) a certain number of times and also chant or listen to a prayer devoted to their religious rites. The Hajj is usually performed in the twelfth month of the Islamic calendar, and should be performed at least once during an Islamic person&#39;s lifetime. The Umrah may be performed at any time of the year, but is often performed during the last ten days of Ramadan. The injunction for compliance with the requirements of the rituals is the same, whether the individual is young or elderly. 
         [0005]    Thus, Mecca is often crowded with pilgrims who have come to perform the rites of their religion during the holy days of the Hajj and Ramadan. The congested conditions, together with the hot climate and the physical exertion of the rites, raises concerns about the health of the visitors, particularly the elderly, as well as directing the pilgrims to the sites where the rites are to be performed, and other matters relating to ensuring that the rites have been observed. 
         [0006]    Thus, a wrist-mounted device to assist pilgrims solving the aforementioned problems is desired. 
       SUMMARY OF THE INVENTION 
       [0007]    The wrist-mounted device to assist pilgrims includes an apparatus and also includes a method for operating the device to assist in performing religious rituals. The device is designed to have many useful functions and provide useful information, for example, measuring heart pulse rates, detecting a light source, counting the number of complete rotations, providing alerts, providing an audio outlet, storing personal information about the individual and providing directional information to specific locations using a GPS navigational system. 
         [0008]    Processors, GPS chips, and sensors are placed in the casing and along the wrist-mounted device&#39;s strap of the wrist-mounted device to assist in performing religious rituals. The processor and sensors are capable of detecting and monitoring an individual&#39;s health vitals, such as heart rate, and alert the individual if the health vitals are outside of a defined parameter. The detection of heart rate allows an individual, such as an elderly person, to monitor their heart rate and temporarily halt his or her rotation or ambulation around the holy site until their heart rate is back within a pre-defined normal range. The processor, GPS chip and sensors are also capable of detecting the initial or start point in a holy site to indicate to the individual or pilgrim where to start performance of religious rituals. 
         [0009]    The wrist-mounted device also allows the individual to listen to an audio transmission incorporating religious chants, such as a collection of prayers. This allows the individual to continue prayers for supplication during the performance of the ritual and obviates the need to read prayers of supplication from books while performing religious rituals, such as completing a number of rotations around the religious site. 
         [0010]    These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.

Although  FIG. 2  illustrates two sensors, it is not limited in this regard, and additional sensors can be added. 
         [0028]      FIG. 3  schematically shows an exemplary depiction of an individual  302  walking around a cuboid building at the center of a mosque  310 . In this example, the cuboid building is titled “Holy Kaaba” and is used to exemplify the religious site for worshippers of the Islamic religion. In the Islamic religion, religious followers are expected to travel to the most sacred mosque, Al-Masjid al-Haram, in Mecca, Saudi Arabia at least once in the follower&#39;s lifetime and follow the Islamic rituals of pilgrimage. For example, during the Hajj and Umrah holy days, Islamic followers are expected to circumambulate the Kaaba seven times, in a counterclockwise direction. 
         [0029]      FIG. 3  schematically shows the individual  302 , a light source  304 , and a satellite  306 . The light source  304  indicates one location that is traditionally designated a start point for the followers of Islam to start their circumambulation around the Kaaba in a counter-clockwise fashion. The light source indicating the traditional start point around the Kaaba is usually shown as a green light in the Islamic religion, but is not limited in this regard. 
         [0030]    The individual  302  wearing the wrist-mounted device  100  can receive and send coordinates  307  to and from the satellite  306  via the wrist-mounted device. The satellite can receive the coordinates  305  of the traditional start point for rotations around the Kaaba, which is usually indicated by a green light, such as the light source  304  in  FIG. 3 . This green light is also an indicator for the individual that he or she has completed a full rotation around the holy site, such as Kaaba. The processor  222  in the wrist-mounted device  100  can register each time the GPS chip  232  is in a close location to the light source  304  as detected by the sensor  112  in order to count the number of complete rotations the individual has done. The sensor  112  can detect the color of the light source, such as a green light, for determining the number of complete rotations. Each time the sensor detects the light source  304 , data signals are sent to the processor  222  to track the number of complete rotations. 
         [0031]      FIG. 4  shows an exemplary depiction of the wrist-mounted device  100  displaying an individual&#39;s heart rate  402 , the completed rotations  404  recognized by the GPS chip, and an audio indicator  406  on the LCD display of the wrist-mounted device, such as the LCD Display  110 .  FIG. 4  also illustrates the watch straps  114 , the LCD activation button  102 , the rotation count button  104 , the location button  106 , and the audio control button  108 . The LCD activation button  102  can switch between showing information, such as the information displayed in  FIG. 4 , and showing the individual age, weight and height information. The LCD activation button  102  can also switch to displaying a digital map with a designated location pinpointed by means of the GPS chip  232 . Additional embodiments may include a number of preset audio or written messages on the wrist-mounted device  100 , and means to allow customizable messages to be stored and recorded into the wrist-mounted device  100 . The LCD display  110  can include a number of visual words, messages and symbols, such as music notes and alarm clocks, but is not limited in this regard, and additional symbols, icons, and images can be displayed. 
         [0032]      FIG. 5  shows a flowchart of a logic tree  500  of an embodiment of a method for operating a wrist-mounted device to assist in performing religious rituals, such as using the general wrist-mounted device  100  of  FIG. 1A  and  FIG. 1B . In the flowchart of the logic tree  500 , at step  502  an individual inputs his or her personal information into the wrist-mounted device. The entering of information can be accomplished by means of a capacitance touch screen or multi-touch interface, as known in the art, and can incorporate the use of a digital keyboard. At step  504 , the individual can press at least one button on the wrist-mounted device  100  to locate the start point to begin rotation around the religious site, such as the Kaaba. 
         [0033]    At this step in locating the start point of the religious site, the GPS chip  232  in the wrist-mounted device is in communication with a satellite, such as the satellite  306  in  FIG. 3 . The GPS chip  232  can send and receive coordinates  307  to and from the satellite, such as receiving the coordinates  305  of the traditional start point of Kaaba, which is usually indicated by a green light, such as the light source  304  in  FIG. 3 . This green light is also indicator for the pilgrim that he or she has completed a full rotation around the holy site, such as Kaaba. The processor  222  can register each time the GPS chip  232  is in a close location to the green light as detected by sensor  112  in order to count the number of complete rotations the individual has done. 
         [0034]    At step  506 , the individual can begin the rotations around the holy site at the starting point, such as the light source  304  in  FIG. 3 . Continuing at step  508 , the wrist-mounted device can track the individual&#39;s location and counts the completed rotations around the holy site. This is illustrated by the GPS count  404  of  FIG. 4 , which shows a GPS signal and a number “4” indicating the number of rotations around the start point of the holy site. In addition to the GPS chip  232  in the wrist-mounted device  100  being able to receive the coordinates  305  for the green light for detecting and counting the start point, the sensor  112  can detect the light source and color of the light source, such as a green light of the light source  304 , to detect the start point for the counting the number of rotations around the holy site. This data corresponding to the detection of the light source and color of the light source by the sensor  112  can be transmitted to processor  222  to count the number of completed rotations around a holy site, such as the Kaaba. The sensors can be various sensors, including photodetectors, photosensors, cryogenic detectors, photodiode light sensors, LED photodiodes, optical detectors, photoresistors, electro-optical, wave-front sensors etc., as is known in the art. The sensors can also be wireless sensors or hardwired for communication, and is not limited in this regard. 
         [0035]    At step  510 , the individual can selectively press a button on the wrist-mounted device  100  to monitor his or her heart rate as detected by the sensor  202 , such as pressing the LCD activation button  102 , which will display the individual&#39;s personal information. At step  512 , the individual can also selectively a press another button on the wrist-mounted device to listen to a religious chant, such as pressing the audio control button  108 . The audio control button  108  can also be adapted to be adjustable to control the sound volume, with one end of the button increasing the sound volume and the opposite end decreasing the sound volume. 
         [0036]    The flowchart concludes at step  514 , as the wrist-mounted device  100  can alert individual if his or her heart rate is outside of a defined parameter. The defined parameter for the individual&#39;s heart rate is pre-programmed into the processor and is based on a variety of factors, such as the individual&#39;s age, height, weight, etc., that is entered into the wrist-mounted device  100  at step  502 . If the individual&#39;s heart rate is within the parameters, the wrist-mounted device  100  will continue operating as pre-programmed. 
         [0037]    Additional embodiments of the wrist-mounted device and the methods for operating the wrist-mounted device allow for the device to display time and date information. Additional embodiments also allow for the wrist-mounted device to maintain multiple calendars, such as the lunar and solar calendar, in order to pinpoint or highlight the holy dates of the individual&#39;s religion, such as highlighting the 8th day to the 12th day of the 12th month in the lunar calendar. The lunar calendar is 11 to 12 days shorter than the solar calendar and the holy dates of the 8th day to the 12th day of the 12th month in the lunar calendar will change every year in regard to the solar calendar. 
         [0038]    It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
