  • the P1 and P2 pushbuttons are used to adjust the minutes, hours, month, day and year.
  • the push button P1 When the push button P1 is pressed for the first time, there is a message on the display (picture 16, Figure 7) which is the word "minute”.
  • the display should in fact present Arabic words.
  • the word "minute” presented in French the same word would be displayed, but in Arabic.
  • the message can be displayed in any other language but, for simplicity, the invention will be described using French words.
  • the word "minute” displayed on the screen when the push-button P1 is pressed for the first time but the value in minutes is also displayed on the display, from the value stored in the appropriate "minute” area of RAM.
  • pressing the push button P2 increases the data representing the minutes by one, stored in the RAM memory and visible on the display.
  • pressing the P2 push button advances the data stored in the RAM memory by one, which changes to the displayed image.
  • pressing the push button ends the RAM data cycle, and the time displayed returns to zero.
  • a message appears (image 18, Figure 7), which is the word "month", with the name of the month in the Gregorian calendar.
  • the name of the month can be any name between January and December.
  • a register 34 of the RAM 24 contains the month number (1 to 12), which is used as the relative address for an indexing table 36 which contains the name of the Gregorian calendar month and has a match with the appropriate name of the Gregorian calendar month found in Table 38.
  • the RAM area 34 increases by one, and it now has a correspondence with the following zone of the indexing table 36, and this zone contains the address, of table 38 of the names of the months of the Gregorian calendar (memory dead ROM 14) where the sequence of characters representing the name of the month begins.
  • the content of the RAM 34 memory area reaches 12, and if the P2 button is pressed again, the cycle is terminated and the value stored in the RAM 34 memory returns to 1.
  • the content of the RAM memory area 40 representing the day of the month increases by one, and the value obtained is presented in display 16.
  • the maximum number of days (plus 1 to indicate when we arrive at a forbidden day) for each of the Gregorian months.
  • this value is compared with the corresponding value found in table 42 (RAM memory), and calculated from knowing the number of the Gregorian month found in register 34.
  • the value of the day in register 40 reaches the invalidity limit (30, 31 or 32 days), it returns to "one" before appearing on the screen.
  • the day of February can reach 29, and it is then that we check if it is is actually a leap year, or not.
  • the date in the Muslim calendar is also automatically calculated.
  • the years of the Muslim calendar follow a 30-year cycle, in which some years are leap years.
  • the list of these years is stored on a table in ROM 14.
  • the length of the month in the Muslim calendar is assumed to change from 29 to 30 days and vice versa.
  • the last month has 29 days in non-leap years and 30 days in leap years.
  • the total number of days since the reference date (January 1, 1983) and any date, is calculated or tabulated.
  • the reference date is then changed from January 1, 1983 to January 1, 1403, by adding 75 days to the calculated total (the date of January 1, 1403, in the Muslim calendar, takes place 75 days before January 1, 1983).
  • the total is then converted into years, months and days of the Muslim calendar, to obtain the exact date of the Hegira (Muslim calendar).
  • the date in the Muslim calendar is stored by year, month and day of the month. From a date known in the Gregorian calendar, we thus calculated the date in the Muslim calendar then, from knowledge of the date in the Muslim calendar and in particular the day of the month, we now calculate the phase of the moon and it is memorized for later display as the shape of the moon 49, as it is presented for example in FIG. 1.
  • the calculation circuit now calculates the time of the next prayer, and stores it in the memory, from where it will be automatically displayed at the desired time, with an acoustic indication. After the name of the prayer and the call to the prayer sequence have been indicated on the display according to the procedure shown in Figure 8, the calculation circuit calculates the time of the next prayer, stores it and then repeats the process. Thus, the time of each prayer is always calculated individually.
  • the name of the day of the week is obtained as indicated in the table in Figure 4.
  • the register 44 of the RAM 24 contains a number (1-7) which represents the day of the week used to locate the address on the indexing table 46 of the ROM 14 of the beginning of the sequence of characters representing the name of the day of the week.
  • the indexing table then points to area 48 of the read-only memory 14, which contains a table of the names of the days of the week in the Gregorian calendar.
  • the name of the month in the Muslim calendar is obtained by a process analogous to that explained for the Gregorian month, as explained above with reference to Figure 2.
  • the large number of cities that can be selected are described by means of a list of parameters stored in ROM 14. These parameters are presented on the table in Figure 5.
  • the name of a certain number of cities, which represent the main localities of the world, are chosen for memorization. There is no restriction as to the number of cities whose names can be selected for storage, except because of the size of the ROM 14 available in the new clock according to the invention.
  • Certain information, such as the telephone code of a particular city or special data, such as emergency telephone numbers or certain business telephone numbers, and the like, may be permanently stored in the ROM 24 for each particular city, or they can be entered by programming in the RAM 24 as will be studied below.
  • the latitude and longitude of the city, as well as the local time of the city in relation to Greenwich Mean Time, as well as the parameters of prayer times for this particular city are all used in the calculation of prayer times.
  • the user To allow the user to select and display a particular city, he presses the P3 push-button, and the name of the selected city appears on display 16. If this city is the particular city of interest to the user, he press P1 to block its selection. If it is not the city which interests him, he can keep the button P3 pressed, and he will see appear on the screen the name of all the cities memorized in the ROM ROM 14 of the clock according to the invention , until the desired city appears. At this time, the user presses the P1 button to block the selection.
  • Pressing the push-button P1 causes the following actions: first of all, the town's serial number is placed in the area of the RAM 50 presented in FIG. 5 and designating this town. It represents the address of the chosen city, memorized on the indexing table 52, which points to its parameters from table 54 in the ROM 14 read-only memory. parameters will be used in all subsequent calculations. Then we have on the screen the Qibla of the new city selected, according to images 14 and 15 (shown in Figure 7), with a flashing of the direction of the Qibla. Then, as shown in Figure 1, an arrow 56 is displayed, the word "North" being presented along the arrow, to indicate the direction of North.
  • a marker 58 begins to flash, which indicates the direction of the Qibla relative to the indicated North.
  • the Qibla 58 is at an angle with respect to the arrow 56 indicating the North, as it is represented by the arc 60.
  • This direction indicated by the arc 60 is memorized as a set of coordinates that indicate the position of this point, or Qibla 58, on the screen.
  • the time presented on screen 16 is automatically converted to the local time of the new selected city.
  • the user does not need to remember the time differences or reset the clock. He just has to select the name of the city he is interested in, and the time automatically adjusts for that city.
  • a question also appears on the screen (image 7, Figure 7), which indicates "Summer Time?". The user must then check the position of the sliding selector S2, which is the selector defining summer time or legal time for the particular city chosen, then he must set this selector to the desired position.
  • the Gregorian calendar and the Muslim calendar are also automatically updated in a case where the time difference between the previous city and the newly selected city requires moving from one day to the next (or to the previous day), by one month to the next (or to the previous month) or from one year to the next (or to the previous year).
  • the special information permanently stored in the ROM 14 can be displayed, in first selecting and displaying the name of the desired city, by pressing the P3 push-button, then by pressing the P4 push-button.
  • the user wishes special information to be stored in the RAM 24, for example the telephone code or an emergency telephone number for a particular city, he will be able to obtain the display of the name of the particular city simply by pressing the P3 button then the P4 button and entering the desired data via the keyboard 13 in a manner known per se.
  • the user can again press the P3 button, which selects the name of the city indicated above, then he presses the P8 button, which gives the display the telephone code, the number of emergency telephone or any special information concerning the particular city selected.
  • the date of the Muslim calendar is calculated from the date of the Gregorian calendar, as explained above.
  • Some Muslim communities adhere strictly to the letter of the law, which requires that a month of the Muslim year cannot begin during the New Moon period. This creates some uncertainty as to the effective dates.
  • Calendars prepared a year in advance can be erroneous for an entire month if the observation of the new moon does not coincide with a calculated start of a particular month. This process is repeated every month, so there is a probability that the published calendars will end up being "wrong" for an entire year.
  • This difference at the beginning of the month is generally more or less a day, and it can sometimes even go up to two days. As this phenomenon occurs at the beginning of the month, the rest of the month (and, in some cases, the year of the Muslim calendar) is shifted.
  • the present invention gives the user the means to eliminate this problem.
  • the user can advance the date on the Muslim calendar by one day (without affecting other settings) and, by pressing the P6 button, the user can delay the date on the Muslim calendar by one day (without affecting other settings).
  • the date, in the Muslim calendar moves forward or backward by one day.
  • the month of the Muslim calendar and the year of the Hegira are then automatically adjusted.
  • image 2 is shown on the display 16 ( Figure 7), even if it does not happen in time, so that the user can see the date that He modifies.
  • the third important moment is to mark the end of the period allowed for the first prayer.
  • the other four moments indicate the beginning of the other prayer periods.
  • the event number takes the value 2, and the time of event number 2, which is the time of the first prayer, is calculated, and the display shows the name of the prayer and the time of the prayer (picture 4, Figure 7).
  • the clock waits for about 3 seconds, then repeats the next event or the next prayer, and so on until the time of the seven events is displayed, after which the clock goes back to display the time of day and calendar date, as before.
  • the prayer time is found, two operations are carried out: first, the prayer time is converted into hours, minutes and seconds, and stored in the RAM 24 in appropriate areas for seconds, minutes and hours. Then, a check is made as to the position of the summer time selector S2. If this selector is in the legal time position, no action is taken. If it is in the summer time position, the hours register of the RAM 24 increases by one, as indicated above.
  • Figure 6 is a flow diagram of the operation of the new prayer clock according to the invention.
  • the decision symbol 56 checks whether any of the push buttons P1, P2, P3, P4, P5, P6, P7 or P8 has been pressed. If so, it explores its pushbuttons and supports them as described above, and as shown by block 58 in Figure 6. When the push buttons have been explored as indicated at 58, the unit returns to step 60 and continues. Similarly, if none of the pushbuttons have been pressed, the output of the decision block 56 is again coupled to step 60, and the next step, indicated at 62, is intended to adjust the time based on the position of the summer time selector. Then, the display is optionally updated from the measurements taken during step 62, which is indicated by step 64.
  • step 66 a decision is made as to whether or not to calculate the time of the next prayer. If the answer is no, the unit goes to step 68. If the answer is yes, the next step is to calculate the time of the next prayer in step 70, as discussed above. . After the time for the next prayer has been calculated in step 70 1 _the unit returns to step 68, taking into account the next step 72, which consists of answering the question "Is it time to say the prayer? ". If the answer is yes, the prayer is indicated in step 74, and it is not only a visual indication on the screen 16, but also an acoustic signal emitted by the audible alarm 32 presented on Figure 1. After step 74, the unit returns to step 76, which, via step 78, returns to the original decision block 56, where the cycle repeats.
  • the prayer step 74 shown in Figure 6 is repeated in detail in Figure 8. If the decision block 72 in Figure 6 decides that it is time to indicate a prayer, the unit 80 in Figure 8 decides whether or not it is prayer number 1. If the answer is positive, he checks to make sure that step 82 is in fact the appropriate month of the Muslim calendar. If the answer is no, the unit simply returns to step 76 of the main logic of Figure 6. If the answer is yes, the next step 84 consists of indicating twice the name of the prayer and display it and sound the horn 32 in Figure 1. The next step 86 is to wait 18 seconds and then, in step 88, to decide whether it is or not , the third time the prayer name has been displayed and the horn has been sounded.
  • step 90 the words relating to the call to prayer are displayed, as illustrated in images 8 to 12 in Figure 7. Then the unit returns to step 76 of the main logic presented in Figure 6.
  • Figure 7 is a table showing the image number that can be displayed, as well as the description of the particular image.
  • the new clock automatically calculates an indication of the Muslim prayer times for any city whose name is displayed, and it displays the calculated prayer times of a visibly, with an audible indication of when they should be said.
  • Special information relating to one or more particular cities such as the area code, emergency telephone numbers, special telephone numbers, local or national holidays, etc., can be stored, searched and displayed permanently or temporarily.
