Definitions

  • the present invention relates to a binary clock comprising electronic time measurement means.
  • Such clocks or electronic timepieces are known, but the time is displayed in these clocks either digitally or analogically, using hands controlled by a stepping motor.
  • the present invention proposes to produce a clock with binary time display.
  • a clock made for example in wall execution, is intended to be used preferably in schools or educational institutes, universities, etc. to familiarize pupils or students with the binary number system.
  • the direction of reading the bits with the weights or powers of two assigned to them can be reversed in order to perfect the training of the observers in binary reading.
  • the clock can display the time simultaneously digitally (display of digits) or analog (display by hands).
  • FIG. 1 shows an example of display comprising three zones I, II and III, respectively to indicate the hours from 0 to 12, as well as the minutes and seconds from 0 to 59. It is of course possible, if desired, to '' display the hours from 0 to 24.
  • Each zone comprises segments 1 each carrying for example three display elements, such as light-emitting diodes LED 2 and 3.
  • the diodes 3, of small dimensions are arranged in the center of each segment and the diodes 2 of larger dimension are arranged at the ends of the segments 1. It is known that in the binary numbering system, a number is composed of a series of bits of value 0 or L, a power of two being associated with each bit.
  • the least significant bit 20 is that located at the extreme right of the number and the most significant bit 2 n is that of the extreme left.
  • each segment represents a bit, the six segments of zones II and III respectively representing, and read from right to left, the bits 20, 21, 22, 23, 24 and 25.
  • These powers of two or weights are displayed by LEDs 3 which light up as the number displayed increases between 0 and 12, respectively between 0 and 59.
  • LEDs 2 indicate that the segment on which they are find represents a bit of value L if they are on or a bit of value 0 if they are off.
  • area III displays the number 28 calculated from the binary system as follows:
  • FIG. 2 shows an exemplary embodiment of a binary display using LED light-emitting diodes.
  • This display comprises an upper glass plate 4 under which are arranged plexiglass blocks 5 in the form of segments 1 and a plastic plate 6 supporting the diodes 2 and 3 and forming the base.
  • a passage 7 is provided in the plexiglass 5 to conduct the light from the central diodes 3 to the lower surface of the glass plate 4.
  • Spherical cavities 8 are provided in the plexiglass, above the diodes 2 of larger dimensions . Knowing that the plexiglass is of milky execution, that is to say not entirely transparent, the above arrangement allows the light from the diodes 2 to diffuse in the plexiglass and to extend in the direction of the length for form the segments 1 of FIG. 1. Each segment therefore behaves optically as a light line when the diodes 2 which it comprises are lit.
  • FIGS. 1 and 2 The arrangement of the display illustrated in FIGS. 1 and 2 is not exhaustive and it is clear that any other arrangement making it possible to display a binary number is included in the present invention.
  • the display can be achieved using several different display technologies such as electro-mechanical, LED, LCD, neon, CRT, laser, incandescent or fluorescent vacuum.
  • FIG. 3 shows a very simplified block diagram of the clock electronics.
  • This includes a quartz oscillator 9 which controls a frequency divider 10.
  • a decoding circuit 11 delivers the signals necessary for a digital display 12 of the time, this digital display being intended to facilitate the learning of binary reading ; it can be put into service or triggered by a switch 13 and it is intended to be incorporated into the binary display or mounted next to it.
  • an analog display 14 with needles and stepper motor controlled through a switch 16 by a control circuit 15 can be incorporated into the binary display or mounted next to it.
  • the analog display 14 is provided for the same purpose as the digital display 12.
  • a multiple switch 17 is provided to reverse the direction of reading of the bits of the binary display, as indicated above.
  • the switch 17 illustrated in FIG. 3 enables the direction of reading of the bits of zone III to be reversed. In the position shown, the least significant bit 2 ° is delivered to the right input f of the logic 18 and the most significant bit 25 to the left input a of the logic 18.
  • This example corresponds to the display of the number 28 illustrated in FIG. 3.
  • the bits 20 and 21 on the inputs f and e of the logic 18 have a value 0, so that the diodes 2 of the corresponding segments are extinguished.
  • the bits 22, 23 and 24 on the inputs d, c and b have a value 1 and the diodes 2 of the corresponding segments are lit.
  • the reading order of the bits is reversed, the least significant bit being delivered to input a and the most significant bit to input f of logic 18.
  • the number displayed 28 must be read with the weights of the bits increasing from left to right, between 20 and 25.
  • the intended reversal of the direction of reading of the bits is intended to perfect the learning. of binary reading and constitutes a gymnastics of the mind.
  • the logic 18 controls the binary display 19 and fulfills various functions such as the control of the diodes 3 indicating the bits to be taken into consideration.
  • any other combination of display elements for indicating the weights and the 0 and L values of the display bits is included within the scope of the present invention.
  • the electronic means provided in FIG. 3 can be used if desired to control a plurality of binary displays 19 and digital 12 or analog displays 14.
  • FIG. 4 shows a more detailed block diagram of electronics which do not include reversing the direction of reading of the bits.
  • Circuit 20 is a supply circuit which also produces synchronous rectangular pulses with the frequency of the network. These signals are delivered to a frequency divider 21 by 50, resp. par 60 depending on the regions in which the network frequency is 50 Hz, resp. 60 Hz.
  • the divider 21 delivers 1 Hz repetition frequency signals to a circuit 22 for controlling the segments 1 of the binary display 19 displaying the seconds (field III of FIG. 1).
  • the circuit 22 also delivers one pulse per minute to the circuit 23 for controlling the segments 1 of the minutes display (field II of FIG. 1).
  • the circuit 23 is coupled to the circuit 24 for controlling the segments 1 of the hour display (field I of FIG. 1) itself connected to the circuit 25 for controlling an AM / PM display.
  • the control information for the minutes and hours of the binary display 19 is delivered to a digital multiplexer 26 which is controlled by a digital selector 27 itself controlled by a time base generator 28.
  • the signals from generator 28 are clock pulses for the digit selector 27.
  • the multiplexer 26 is informed of the selected digit and of the time to be displayed (minutes and hours). These two pieces of information are necessary to determine the digit to be displayed and they are supplied to the coding circuit 29 for the correct control of the segments of the digital display 30.
  • a new digit is formed with each new clock pulse and the cycle is sufficient fast to avoid flickering of the display 30.
  • the invention does not apply exclusively to clocks, but to any timepiece such as a watch, wristwatch, alarm clock, etc.
