The Casio Wave Ceptor is a line of radio watches by Casio. Wave Ceptor watches are able to calibrate themselves to the correct time by receiving time signals from various government time services around the world. These signals are normally driven directly by ultra-accurate atomic clocks, and so by synchronizing with the signals, the Wave Ceptor watches achieve long-term accuracy - the same accuracy as the atomic clocks that drive the time signals, which is on the order of one second in three million years.
The Wave Ceptor watches are not the only radio-controlled wristwatches on the market. The German manufacturer Junghans and Japanese manufacturer Citizen Watch Co. also have this feature. Like most radio-controlled watches, the Wave Ceptor watches require no setting or resetting of time, date, daylight saving time, or year; and like most other watches of this kind, they synchronize at least every 24 hours, usually in the middle of the night. Their long-term and short-term accuracy is thus better than 500 ms.
A weakness shared by the Wave Ceptor watches with other radio-controlled watches is that they revert to merely free-running quartz accuracy in areas out of range or shielded from time setting signals. The time setting signals usually come from radio emitting towers. However, they are still as accurate as other quartz watches in this mode.
Предимствата на радио-контролирани часовници са очевидни: След като те са са настроени веднъж за съответния часови пояс, те винаги показват точно местните времена според часовият пояс и държава. Всички радио-сверяеми CASIO часовници получават сигнали почти навсякъде в Европа.*За съмняващи те се относно България сигналът се получава навсякъде. Някои модели дори получават сигнали в Северна Америка, Канада и части от Мексико (радио кула във Форт Колинс изпраща сигнали за радиус от до 3200 км) и дори в Япония или Китай .. В Европа, промяната от лятото до зимата е напълно автоматична. Тук можете да научите за технология.
Редовно приемане на сигнала гарантира, че часовникът винаги показва точното време. Точното време се предава на часовника от атомни часовници - най-точните часовници в света. Няма нежда от настройка, винаги навреме и точни.
Атомни часовници
Атомни часовници са най-точни часовници в света. В Германия, официалното време е установен в Physkalisch-Technische Bundesanstalt в Брауншвайг Националния институт метеорология. Във Великобритания, Националната физическа лаборатория в Teddington близо до Лондон е отговорен за това task.In САЩ, тази работа се извършва от Националния институт за стандарти и технологии (NIST) във Форт Колинс / Колорадо. В Япония, официалното време се определя от изследователска лаборатория за регулиране на съобщенията (CRL) в Токио. В Китай, времето е изпратено от Националния Център за обслужване на време.
Атомни часовници не се отклоняват . В продължение на един милион години, те биха могли да "теоретично" попадат прибл. една секунда в синхрон. За да си преставите това в сръвнение: кварцовите часовници се разминават на няколко секунди в синхрон всеки месец. Механични часовници - без значение колко сложни са те - се разминават с много повече секунди.
Приемане на сигнала
Времият импулс до крайна прецизност е получено от атомните часовници и е изпратено до радио towers.In Германия, кулата се намира в Mainflingen близо до Франкфурт. Във Великобритания, кулата може да се намери в Anthorn. В САЩ, кулата се намира във Форт Колинс. Кулата в Япония може да се намери в Fukushima в Североизточния и Фукуока в югозападната част. В кулата за Китай се намира в шангкиу. Радиото кула в Mainflingen достига часовници с радио - технология в радиус от 1500 км в зависимост от модела. Една особеност на някои радио-часовници CASIO е, че те са оборудвани за приемане на сигнали от всичките шест предаватели.
Чистотата на сигнала
В Германия, DCF77 момента сигналът се предава на честота 77,5 KHz. MSF е сигнал от Великобритания и WWVB е сигнал в САЩ - и двете са предадени с честота 60 KHz. Двете японски JJY сигнали се предават с честота 40 KHz и 60 KHz. Китайските сигнал БФК е изпратен на честота 68 KHz. В радио-контролните нива на приемане часовниците декодират съответния сигнал и показват точното местно време до 0.0000000000000000001 от секундата.Извън обсега на приемане, CASIO радио часовниците продължават да работят като нормални кварцови часовници.
This CASIO-original high-capacity solar power system combines a super-sensitive solar panel that generates power even under low fluorescent light with a high-capacity rechargeable battery that operates the various high-load functions with ease. This ensures that Tough Solar watches never need a battery change.
You need both hands for many outdoor activities, and you don't always have one free to illuminate your watch face in low-light conditions. The Auto Light Switch solves this problem by illuminating the backlight whenever you turn your wrist to bring the watch into the viewing position.
The newly developed dual-layer LC Display features a blue deflector plate attached at the top of the upper liquid-crystal layer and a red defector plate attached at the top of the lower layer. Added to these, an RDF-C sheet covers the bottom surface of the lower layer. This innovative structure has enabled us to realize excellent visibility and high-impact color.
Direction sensor This magnetic sensor employs two perpendicularly intersecting internal coils with a centrally located MR (magnetic resistance) element to sense geomagnetism (a magnetic force traversing Earth in the north/south direction) and use it to determine directions. An MR element is a resistance element whose resistance characteristically changes depending on the strength of the magnetic force. It is structured such that its sensing power varies with the geomagnetic angle. The MR element employed by the direction sensor is insufficient, because the geomagnetism is weak and the directivity complicated. Two sets of coils have consequently been adopted to divide the components into a more rational, right-angled, two-directional intersection. When the MR element detects the various components, a microprocessor processes the voltage signals received as the resistance changes and determines the direction.
Pressure sensor The pressure sensor employs the "piezo effect" of the resistance change occurring when four diffusion resistances arranged on a silicon base are distorted to measure pressure. Outside pressure on the silicon base depresses the surface because of its flexibility and its internal vacuum structure. The diffusion resistance expands in accordance with the movement of the base and the changes in resistance. Since this diffusion resistance is included in the circuit through which a fixed electric current passes, a voltage difference occurs before and after the resistance. Atmospheric pressure and water pressure are computed by digitizing this voltage difference with the A/D converter and processing it by microprocessor.* *The microprocessor incorporates data on the International Standard Atmosphere (ISA) defined by the International Civil Aviation Organization (ICAO). It compares this with the atmospheric pressure information collected to make high-level conversions instantaneously.
Temperature sensor The PROTREK Thermosensor's temperature sensor converts voltages specified by the resistance at the current temperature into a frequency by means of a frequency conversion circuit (CR oscillation circuit). A microprocessor receives the frequency signals, processes them and employs the results to compute the temperature. * The Triple Sensor and Twin Sensor are equipped with an A/D converter for pressure measurement that they use to transform the pressure difference before and after thermistor measurement to digital signals, which they then process with a microprocessor to determine the temperature.

The drop test is performed manually by actually dropping watches. A test machine cannot be used for such a test, because there is no way to control or reproduce all of the countless variables involved when an object falls.
The cushioning system of the watch also provide outstanding resistance to vibration. In the past, vibration resistance was tested by fixing the watch to the axle of a motorcycle. Today, a special test machine is used to subject the watch to vibration for 24 hours to check its ability to withstand such treatment.
The unique G-SHOCK design also provides it with the ability to withstand the rigors of water resistance testing up to 20 atmospheres, which is equivalent to 200 meters. This means unequalled toughness, even under water.
