Description

CLOCK AND CHRONOMETER WITH ANALOGIC AND DIGITAL SCREENS TRANSFERRED AND SEPARATELY ACTIVATED FIELD OF THE INVENTION The present invention relates to the field of electronic clocks, i.e. clocks having an electronic oscillator, such as a quartz crystal oscillator, which serves as the time pattern for the watch. More specifically, the present invention relates to display technologies for electronic clocks, wherein the display arrangement includes time indicators, both analog and digital.

BACKGROUND OF THE INVENTION To receive a reasonable acceptance by the consumer, a wristwatch, electronic, modern, or other watch for use in the body, must have certain characteristics and basic capabilities. First, it must have, quite accurately, errors of less than 10 seconds per month and these are common in the industry. It should be convenient in its use and have a screen for viewing the time, quite visible, preferably a screen easily visible, both in bright sunlight and in low light conditions. The cost of acquisition and maintenance of the watch must be reasonable. Finally, it must have a combination of features, screens, and global appearance, that are sufficiently innovative, or otherwise attractive, to make consumers want to use it. The clocks that incorporate a conventional screen of the analog type, mechanically driven, and an electrically excited digital screen, have become popular as both consumers and manufacturers have understood that both types of screens have certain advantages in applications for electronic timepieces. in the body. When electronic watches were a recent novelty, consumers typically "wanted to get attention" that they had an electronic watch, by having a watch that had some kind of digital display visible. In those times, "solid state" watches were considered by many, more reliable, more prestigious, and more desirable than their outdated, mechanically driven counterparts. The watchmakers then sought to satisfy consumer demand by developing electro-optical digital displays that were suitable for applications in wristwatches electronic watches. However, the watches with digital screens, initial, offered by the manufacturers, had many disadvantages. Wristwatches, with digital displays with electroluminescent diode (LED), were very bulky and consumed a lot of energy, so the screen was usually off, requiring a double manipulation by the user to make the screen "turn on". In addition, although the digital screens were highly visible at night, it was very difficult to read them in the bright light of the sun. The first liquid crystal displays (LCD) used in electronic watches consumed much less energy than LEDs, but these screens had unacceptably short life times. The first liquid crystal displays also had contrast problems that limited users to very narrow viewing angles. Advances in the technology of electronic components, screens, and batteries, have solved many of these problems, making the electro-optical screens common, much more practical for applications in watches for use in the body. However, although the commonly available digital displays are much more practical for watch applications than their predecessors, the preferences of the users have changed. Since the electronic clocks came to get in the market, cheaper and more easily, their "prestige" disappeared. Consumers also understood that, although a digital screen was convenient in some aspects, it was inconvenient in many others. Speaking in general, it is easier to tell the time by looking at an analog clock face, than by reading a relatively small group of numbers. In addition, it is believed that consumers prefer analog displays to evaluate time intervals quickly, that is, how much time has elapsed since a certain period of time, or how much time is left before a specified time. For example, if it is 2:25 and you have an appointment at 3:00, consumers may find it easier to determine on an analog screen, that 35 minutes are missing for the appointment. For these reasons, wristwatches that contain analog and digital displays have become popular. A certain number of these types of wristwatches do not really contain analog components, but rather use an electronic screen that simulates an analog screen. The following North American patents describe all dual electronic displays, wherein the analog type portion of the screen (ie, a radial screen similar to the clock face which is used to express the day in hours and minutes) does not include a schedule and a minute, mechanically operated, conventional: US Patent No. 4,198,810, issued April 22, 1980 by Fahrenschon; U.S. Patent No. 4,077,032, issued February 28, 1978 to Volkman; U.S. Patent No. 4,095,405 issued June 20, 1978 to Tanaka; and U.S. Patent No. 4,320,484 issued March 16, 1982, from Burdet. On the other hand, the North American patent no. 3,911,665, issued October 14, 1975 by van Berkum, describes a wristwatch having analog, mechanically driven, and digital, electrically excited, complementary displays. However, Van Berkum's alphanumeric digital display is limited to the display of the date when it is activated by the user. When activated by the user, the seconds that pass can be presented electronically through a "second marker", described as a single LED or a relatively small group of LEDs, which flash at a rate of 1 Hz. U.S. Patent No. 4,436,435 issued March 13, 1984, by Ushikoshi, discloses a wristwatch having complementary analogue and digital displays, wherein the digital display is located above (or approximately in the same plane) of the sphere analog clock, thus allowing a global, slim design. The wristwatch described by Ushikoshi provides a conventional analogue display that may or may not include a second hand, and a complementary digital display that indicates the hours and minutes in an alphanumeric format. The digital display may or may not include an alarm indicator and two flashing points between the hours and minutes, which indicates the minutes that pass. In the Ushikoshi wristwatch both displays are excited by a single battery and a single time pattern and timing circuit. The present invention comprises a dual-screen electronic wristwatch, which incorporates a novel arrangement of analog and digital displays, and which uses separate batteries, time patterns, and exciter circuits for each screen. Rather than presenting the same time-of-day information, in two separate formats, or the related information of the time and date, as described in the prior art described above, the present invention displays the information of the time of day, in analog format, and the seconds that pass, in alphanumeric format. In this way, the present invention consists, both in a clock and in a chronometric instrument, allowing the user to easily determine, both the time of day and the time elapsed between successive events, with reasonable precision. Finally, the present invention provides an attractive and particularly unique appearance.

SUMMARY AND THE BEST WAY TO TAKE THE INVENTION TO PRACTICE The present invention consists of a clock and chronometer that displays the time of day in an analogue screen format, superimposed over seconds that pass, displayed alphanumerically on a liquid quartz digital screen. The watch comprises a watch case, with a display aperture which, for the purposes of the description, is designed as the display area, a transparent crystal, an electrically excited, liquid quartz digital display, which is substantially the same size that the display area, an electric exciter of the digital display, an analogical, electrical, conventional clock mechanism, and an analog screen comprising a schedule, a minute hand, and an interior window. The digital liquid crystal display indicates the seconds elapsing, displaying, in increments, either digits from 00 to 59, or digits from 01 to 60, for one second each, either in dark numbers, on a luminous background, or vice versa. The digital screen, which may include luminescent surfaces on one or more of its components, is superimposed on the digital screen, and arranged in such a way that the digital liquid crystal display is observed through the opening of the interior window. The hands of the analog display are driven by a clock, analog, electric mechanism, located below the liquid crystal display comprising a battery, a timing pattern, such as a quartz crystal oscillator, a timing circuit , a conventional spike and crown assembly, and an assembly for the movement of the hands, which extends upwards and through the liquid crystal display and which is coupled to the hands of the analog clock. The exciter of the digital display is also located, behind the liquid crystal display, is coupled to the digital liquid crystal display and comprises a battery, a timing pattern, such as a quartz crystal oscillator, and circuit assemblies of timing and exciters of the screen. The analog and exciter mechanism of the digital display can share the same electrical connection to ground, but are electrically isolated from each other. The watch may also include marks on the interior window, which make it easier to read the time of the analog screen, and / or one or more outside windows attached to the watch case, outside the display area marked with analog indications of The time. The watch case may also include a curved back surface, to ensure a comfortable fit on the wrist.

DESCRIPTION OF THE INVENTION The present invention comprises a dual-screen electronic clock, which incorporates a novel arrangement of analog and digital displays, which uses separate batteries, time patterns, and exciter circuits for each screen. Rather than displaying the same information of the time of day, in two separate formats, or the related information of the related time and date, as described in the prior art, described above, the present invention exhibits the information of the time of day, in analog format, and the seconds that pass, in alphanumeric format. Finally, the present invention provides an attractive and particularly unique appearance. This description describes numerous specific details that include the specific structures and circuits, in order to provide a complete understanding of the present invention. A person skilled in the art will appreciate that the invention can be carried out without these specific details. Furthermore, while the description focuses on the application of the present invention to wristwatches, one skilled in the art will recognize that the present invention can also be applied in the context of any horological instrument. Figure 1 shows the present invention 100 in a wristwatch mode, as a user would see it. As shown in Figure 1, the watch 100 includes a watch case 101. Observing through the transparent glass 104 (not shown in Figure 1) and the display aperture 102 in the watch case 101, the user observes the digital display 105 and the alphanumeric digits 106. Superimposed on the digital display 105, the user observes a time slot 108, a minute timer 109, and an indoor rear window 110 comprising the analog screen. The inner rear window 110 is symmetrically aligned with the display aperture 102, and further comprises an inner edge 110b defining the interior opening of the interior rear window 110 and the markings 110c that facilitate the reading of the time of day, indicated by the position of the schedule 108 and minute hand 109. The alphanumeric digits 106 displayed on the liquid crystal digital display 105 have a dimension such that they can be observed through the interior opening of the interior window 110, without being blocked by the interior window 110. In the embodiment shown in figure 1, the interior window marks 110c comprise long segments radially dispersed at intervals of approximately 15 degrees, and short segments dispersed radially between the long segments, at approximately 3 degree intervals. Although Figure 1 shows short and long segments indicating the conventional position of the hours and minutes, in a watch, one skilled in the art will recognize that the 110c marks of the interior window could comprise a variety of other indications such as Roman characters, Arabic or other alphanumeric characters, alone or combined with segments, dots or other marks or indications that are used to facilitate the determination of the time of day indicated by the positions of time slot 108 and timer 109. In a preferred embodiment of the present invention, a luminescent material or coating can be applied to the observation surface of the schedule 108, minute hand 109, and, either to the markings 110c of the interior window, or to the surface of the interior window 110, thus allowing the user to easily read the analog screen, in conditions of low ambient lighting. The schedule 108 and the minute hand 109 are set as in a conventional clock using a spike and crown assembly 119. Figure 2 is a cross section of a wristwatch embodiment of the present invention, showing the arrangement of the different components within the interior 103 of the watch case 101 and the back cover 118 of the watch. As shown in figure 2, the glass 104 covers the viewing aperture 102 in the watch case 101. The crystal 104 is retained by the outside rear window 114, which may or may not be marked with indications used to facilitate reading of the time of day, from the position clockwise 108 and 109. Immediately below the glass 104, figure 2 shows a cross-sectional view of the minute hand 109, the time slot 108, and the inside rear window 110. The analog hands 108 and 109 are coupled to the assembly 112 of the mechanism of the hands, and rotate around it, which extends upwards from the analog clock mechanism 111, through the central aperture 107 which is on the liquid crystal digital display 105. The central aperture 107 is symmetrically aligned with the interior rear window 110 and with the display aperture 102. The analog hands 108 and 109 can be manually positioned using the crown and crown assembly 119 (not mo shown in Figure 2). The analog clock mechanism 111 is a quartz crystal or other analog, electronic, integrated, battery-operated clock mechanism, well known in the art, such as a Citizen 2026 or other clock mechanisms, readily available, and therefore it is not described in detail here. The analog clock mechanism 111 includes a conventional spike and crown assembly 119, and a conventional assembly 112 for the movement of the analog hands, which ordinarily would have been spread across the face of a conventional clock, to be coupled to a schedule 108. and a minute hand 109. Figure 2 shows a liquid crystal display driver 113, in cross section, adjacent to an analog clock mechanism 111. The exciter 113 of the liquid crystal display is electrically connected to the liquid crystal display 105 through a connector for Z-time 117. FIG. 2 also shows the relative positions of the edges of the display aperture 102, the rear window interior 110, and liquid crystal display 105, in a preferred embodiment of wristwatch. The inner rear window 110 is of a size such that the outer edge 105c of the liquid crystal display 105 is hidden from the observation through the glass 104 of the watch. In other words, the outer edge 110a of the inner bezel extends beyond the outer edge 105c of the liquid crystal display 105. The inner edge 110b of the inner bezel 110 is smaller than the outer edge 105c of the glass screen liquid 105. The viewing aperture 102 in the watch case 101 is sized such that the outer edge 110 a of the inner window 110 is hidden from the view of the user. One skilled in the art will recognize that although the wristwatch mode of the present invention described in this description shows a circular design for the watch case 101, the display aperture 102, the interior rear window 110, and the screen liquid crystal 105, the present invention can be implemented in watches with other physical forms (such as square, rectangular, oval, etc.) without departing from the present invention. In addition, although not shown in Figure 2, the watch case 101 may also include a curved back surface, to ensure a comfortable fit on the wrist. Figures 3A and 3B show the front and back sides of the exciter 113 of the digital display. The exciter 113 of the digital display includes the timing pattern and the sets of circuits necessary to excite the liquid crystal display 105 at a rate of 1 Hz. In the embodiment described in the description, the exciter 113 of the digital display comprises a printed circuit board, two-sided, with the following CMOS electronic components mounted on the surface: integrated circuit 120 of the screen exciter, electronic timing pattern 121, integrated circuit chip capacitors 122-125, all shown in Figure 3B. The set of timing circuits, which use an electronic timing pattern, such as a quartz crystal oscillator and a set of electronic circuitry for excitation of the liquid crystal display, for horological applications, are well known in the prior art and therefore, in this description, no additional details are needed or no additional details are provided regarding the specific components of the screen exciter 113. Figure 4 shows an approaching view of the liquid crystal digital display 105. The characteristics of the liquid crystal digital display 105 shown in Figure 4 include an outer edge 105c, two alphanumeric displays 106, each of which comprised of 7 segments 115 uniquely configured and separately illuminated, a bottom 116 of the screen, and a central aperture 107. the liquid crystal display 105 may be configured with a commonly dark background 116, and ordinarily dark segments 115. When the segments 115 receive the energy supplied by the exciter 113 of the screen, they become bright, thus producing alphanumeric, luminous characters, 106, on a dark background 116. Alternatively, the digital liquid crystal display 105 may be configured with a background commonly clear 116 and with commonly clear segments 115. In this embodiment, when the segments 115 receive exciter power 113 from the screen, they become dark, thus producing dark alphanumeric characters 106 contrasted with the light background 116. Figure 5 shows the appearance of the dark alphanumeric characters 106 on a light background 116 in an embodiment of the present invention, wherein the liquid crystal digital display 105 exhibits the alphanumeric characters from 00 to 59. One skilled in the art will appreciate that alternative embodiments of the present invention may display alternative characters, such as from 01 to 60, from 0 to 59 (where digits 0-9 are not displayed with a 0 forward), or from 1 to 60 (where digits 1-9 are not displayed with a 0 forward). Similarly, embodiments exhibiting only a subset of characters 00-59 or 01-60, at a ratio of less than 1 Hz, will not depart from the present invention. In other words, a modality comprising a digital liquid crystal display displaying alphanumeric characters 00, 10, 20, 30, 40, and 50, for approximately 10 seconds each, but in all aspects identical to this description, is not will depart from the present invention. The latter mode is not a preferred embodiment, however, that mode would render the chronometric function of the present invention less useful, FIG. 6 is a top view, of a wristwatch embodiment of the present invention, from the back, with the back cover 118 removed. Figure 6 shows the relative positions of the analog mechanism 111 with the battery 126 of the analog mechanism, and the exciter 113 of the digital display with the battery 127 of the exciter of the digital display. Another that possibly shares the same electrical connection to ground through the watch case 101, the analog mechanism 111 with the battery 126 of the analog mechanism, is electrically isolated from the exciter 113 of the digital display, and from the battery 127 of the exciter of the digital screen. Consequently, in this embodiment of the present invention, the screen exciter 113, or the display driver battery 127, may fail without causing the analog mechanism 111 or analog movement battery 126 to fail, and without impacting the ability of the user of the present invention, to determine the time of day, of the analog screen. In summary, the present invention consists of a clock and chronometer that displays the time of day, in an analogue screen format, superimposed on the seconds elapsed, displayed alphanumerically on a digital liquid crystal display. The watch comprises a watch case with a back cover and a display aperture which, for purposes of this description, is designed as the display area, a transparent glass, an electrically excited, liquid crystal display, which is substantially the same size as the display area, and an analog screen comprising a schedule, a minute hand, and an interior rear window, an analog, electric clock mechanism, and a digital display driver. The digital liquid crystal display indicates the elapsed seconds, displaying, in increments, either digits from 00 to 59, or digits from 01 to 60, for one second each, either with dark numbers on a light background, or vice versa. The analog screen, which may include luminescent surfaces on one or more of its components, is superimposed on the digital screen, arranged in such a way that the digital liquid crystal display is observed through the interior opening of the interior window. The hands of the analog display are driven by an analog, electric clock mechanism, located below the liquid crystal display comprising a battery, a timing pattern such as a quartz crystal oscillator, synchronization circuit assemblies , a spike and crown assembly, and an assembly for the movement of the hands, which extends upwards and through the central opening of the liquid crystal display and which is coupled to the analog clock hands. The exciter of the digital display, also located behind the liquid crystal display, is connected to the digital liquid crystal display, and comprises a second battery, a timing pattern, such as a quartz crystal oscillator, and components and circuit assemblies, electronic, timing and screen exciters. The analog mechanism and the exciter of the digital display can share the same electrical connection to ground, but they are electrically isolated from each other. The watch may also include marks on the interior window, which facilitate the reading of the time of day, on the analog screen, and / or one or more outside windows attached to the watch case, outside the display area, which may be marked with analog indications of the time. Other embodiments of the invention will become apparent to those skilled in the art, after considering this specification or after putting the disclosed invention into practice. The above specification and examples are exemplary only, and the true scope of the invention is indicated by the following claims.
