2 results about "Radio clock" patented technology

A radio clock or radio-controlled clock (RCC) is a clock or watch that is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock. (Alarm clocks with broadcast radio receivers, a totally different concept, are often called "clock radios".) 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 GPS. Such systems may be used to automatically set clocks or for any purpose where accurate time is needed. RC clocks may include any feature available for a clock, such as alarm function, display of ambient temperature and humidity, broadcast radio reception, etc.

Radio clock repeater

To provide a radio clock repeater that can be attached in position by a single hand without losing components.SOLUTION: A radio clock repeater comprises: a slave unit body 21 that outputs a pseudo-standard radio wave; a slave unit casing 12 in which the slave unit body 21 is housed; a fastener 13 which is provided at the slave unit casing 12 and fastens the slave unit casing 12 to a wall surface fixture F; and a fixture 16D for fixing a radio clock C to the front of the slave unit casing 12. The fastener 13 includes a plate body 14 formed with a wall-hanging hole 14A into which a tip Ft of the wall surface fixture F is inserted, and a lock member 15 which is located below the wall-handing hole 14A and prevents the tip Ft from coming off. The lock member 15 includes a leaf spring member 15A fixed to the plate body 14, and a non-fixing part 15B attached to the leaf spring member 15A and capable of coming close to or separating from the wall-handling hole 14A. The non-fixing part 15B is biased to be in a state of being close to the wall-hanging hole 14A.SELECTED DRAWING: Figure 7

Circadian rhythm lighting controller based on radio clock and LED driving module and lighting system having the same

The application discloses a circadian rhythm lighting controller based on a radio clock, an LED driving module and a lighting system with the same, and the lighting controller comprises a radio clock module receiving time coding information in the form of low-frequency radio waves, a storage device storing lighting parameters related to the time information, an MCU module and a dimming controller; the MCU module receives a timing signal sent by the radio clock module and decodes the current time information; the storage device is accessed to find the lighting parameters matched with the current time; then the lighting instructions are obtained or converted; the dimming controller generates corresponding control signals according to the lighting instructions and sends the control signals to the driving circuit of the lighting load. The radio clock module directly receives the standard time coding signal emitted by the national time service station, and the time error can be controlled within milliseconds, so that an absolute accurate and never-drifting time source is provided for the circadian rhythm lighting.
