  • Patent number: 7385879
    Abstract: A radio-controlled clock (RCC) for receiving and decoding a transmitted time signal to display a precise time in accordance with a time standard. A light emitting diode (LED) display emits sufficient light for easy readability under all lighting conditions, including the time numerals. A signal reception indicator remains lit if the RCC has successfully decoded a time signal. If the time signal is currently being received and decoded, the signal reception indicator flashes. If the decoding is unsuccessful, the signal reception indicator will be unlit until the next decoding attempt. A power transformer to supply current to electronic circuitry contained within in the housing of the RCC is located in the power line cord, as at the plug end, to minimize electromagnetic interference with the decoding of the time signals. A signal strength indicator may have multiple segments to indicate if the received signal is strong, medium, weak or too weak for decoding.

  • Patent number: 5359577
    Abstract: An alarm clock has an ambient light detector for controlling the illumination of a time displaying section. An alarm time which is selected by a user is stored in a memory. An alarm set switch is used to switch between alarm-on and alarm-off conditions. A photosensor detects the ambient light surrounding the alarm clock. The illumination of the displaying section is controlled so that the displaying section is illuminated only when the current time is within a predetermined time zone before the alarm time set by the user, the alarm set switch is in the alarm-on condition and the detected ambient light is below a predetermined level. The illumination of the displaying section is also controlled so that the display is illuminated while an alarm sound is being generated.
