Radio Clock
A radio clock or radio-controlled clock (RCC), and often colloquially (and incorrectly) referred to as an "atomic clock", is a type of Quartz clock, quartz clock or watch that is automatically Synchronization, synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock. Such a clock may be synchronized to the time sent by a single transmitter, such as many national or regional time transmitters, or may use the multiple transmitters used by satellite navigation systems such as Global Positioning System. Such systems may be used to automatically set clocks or for any purpose where accurate time is needed. Radio clocks may include any feature available for a clock, such as alarm function, display of ambient temperature and humidity, broadcast radio reception, etc. One common style of radio-controlled clock uses time signals transmitted by dedicated terrestrial longwave radio transmitters, which emit a time code that can be demo ...

Alarm Clock
An alarm clock or alarm is a clock that is designed to alert an individual or group of people at a specified time. The primary function of these clocks is to awaken people from their night's sleep or short naps; they can sometimes be used for other reminders as well. Most alarm clocks make sounds; some make light or vibration. Some have sensors to identify when a person is in a light stage of sleep, in order to avoid waking someone who is deeply asleep, which causes tiredness, even if the person has had adequate sleep. To turn off the sound or light, a button or handle on the clock is pressed; most clocks automatically turn off the alarm if left unattended long enough. A classic analog alarm clock has an extra Clock face, hand or inset dial that is used to show the time at which the alarm will ring. Alarm clock functions are also used in mobile phones, watches, and computers. Many alarm clocks have radio receivers that can be set to start playing at specified times, and are know ...

Smartwatch
A smartwatch is a portable wearable computer that resembles a wristwatch. Most modern smartwatches are operated via a touchscreen, and rely on mobile apps that run on a connected device (such as a smartphone) in order to provide core functions. Early smartwatches were capable of performing basic functions like calculator watch, calculating, displaying digital time, translating text, and playing games. More recent models often offer features comparable to smartphones, including apps, a mobile operating system, Bluetooth and Wi-Fi connectivity, and the ability to function as portable media players or FM broadcasting, FM radios. Some high-end models have cellular capabilities, allowing users to make and receive phone calls. While internal hardware varies, most smartwatches have a backlit Liquid-crystal display, LCD or OLED electronic visual display and are powered by a rechargeable lithium-ion battery. They may also incorporate GPS navigation device, GPS receivers, digital cameras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Umbrella Antenna
An umbrella antenna is a capacitively top-loaded wire monopole antenna, consisting in most cases of a mast fed at the ground end, to which a number of radial wires are connected at the top, sloping downwards. One side of the feedline supplying power from the transmitter is connected to the mast, and the other side to a ground (Earthing) system of radial wires buried in the earth under the antenna. They are used as transmitting antennas below 1 MHz, in the MF, LF and particularly the VLF bands, at frequencies sufficiently low that it is impractical or infeasible to build a full size quarter-wave monopole antenna. The outer end of each radial wire, sloping down from the top of the antenna, is connected by an insulator to a supporting rope or cable anchored to the ground; the radial wires can also support the mast as guy wires. The radial wires make the antenna look like the wire frame of a giant umbrella (without the cloth) hence the name. Design The antenna is supported ...

RJH69
The "Vileyka" VLF transmitter is the site of the 43rd Communications Center of the Russian Navy (), located west of the town of Vileyka in Belarus (). The "Vileyka" VLF transmitter is an important facility for transmitting orders to submarines in the very low frequency range. Beside this, it is used for transmitting the time signal RJH69 at certain times. In common with the former Goliath transmitter of the ''Kriegsmarine'' in World War II, the antenna system of the "Vileyka" VLF transmitter consists of three antenna systems with a central mast insulated against ground from which antenna wires run to six grounded ring masts, where they are fixed by insulators. As at former Goliath transmitter, three ring masts carry two antenna systems, so there are only 15 ring masts on the site. A further common ground to former Goliath transmitter is, that the ring masts of the Goliath transmitter are masts of lattice steel with triangular cross section, while the central masts are steel tube ...

Casio Wave Ceptor
The Wave Ceptor series (stylized as WAVE CEPTOR or WaveCeptor) is a line of Radio clock, radio-controlled watches by Casio. Wave Ceptor watches synchronise with radio time signals broadcast by various government time services around the world. These signals transmit the time measured by atomic clocks accurate to one second in millions of years. By synchronizing daily with the signals, the Wave Ceptor watches achieve high accuracy, using a Quartz clock, quartz crystal to keep time in the interim. Some radio watches, including some Wave Ceptors, are Solar-powered watch, solar-powered, supported by a rechargeable battery. The watch displays may be fully digital, analog, or analog-digital. Hybrid Wave Ceptor models support GPS satellite reception of both time and location, in addition to broadcast signals. Radio-controlled watches require no setting of time and date, or daylight saving time adjustments, as they attempt automatic synchronization several times every night. Without synch ...
