Method and system for managing an alarm signal, alarm clock comprising such a system
View Patent ↗The invention relates to a method and a system (SYS) for managing an alarm signal in a system comprising a first internal clock. The system is intended to cooperate with a portable player (PP) comprising a second internal clock and a screen (S). The method comprises the steps of: —setting the time of said first internal clock at the time of said second internal clock, —selecting a given time value being displayed on said screen, —memorizing said given time value in said system, —setting the time of said second internal clock at the time of said first internal clock, —triggering an alarm signal on said system when the time of said first internal clock reaches said given time value. According to this method, when the portable player is docked to the system, the system according to the invention does not require its own screen because the screen of the portable player is used to display the current time and the alarm time during setting it, resulting in a reduction of the costs of the system.
1. A method of managing an alarm signal in a system comprising a first internal clock, said system being intended to cooperate with a portable player comprising a second internal clock and a screen, said method comprising the steps of:
setting the time of said first internal clock at the time of said second internal clock,
receiving a given time value,
storing said given time value in said system,
restoring the time of said second internal clock at the time of said first internal clock,
triggering an alarm signal on said system when the time of said first internal clock reaches said given time value.
2. Method as claimed in claim 1 , further comprising a step of generating an audio signal on said system, for use as said alarm signal.
3. Method as claimed in claim 1 , further comprising a step of receiving an audio signal from said portable player for use as said alarm signal.
4. Method as claimed in claim 1 , wherein the screen of said portable player comprises a backlight that can take a switched-on state or a switched-off state, said method further comprising a step of sending one or more commands from said system to said portable player to maintain the backlight of said screen in switched-on state.
5. A system for managing an alarm signal, said system comprising a first internal clock, said system being intended to cooperate with a portable player comprising a second internal clock and a screen, said system further comprising:
means for setting the time of said first internal clock at the time of said second internal clock,
means for receiving a given time value,
a memory for storing said given time value,
means for restoring the time of said second internal clock at the time of said first internal clock,
means for triggering an alarm signal when the time of said first internal clock reaches said given time value.
6. System as claimed in claim 5 , further comprising means to generate an audio signal used as said alarm signal.
7. System as claimed in claim 5 , further comprising means to receive from said portable player an audio signal for use as said alarm signal.
8. System as claimed in claim 5 , wherein the screen of said portable player comprises a backlight that can take a switched-on state or a switched-off state, said system further comprising means for sending one or more commands to said portable player to maintain the backlight of said screen in switched-on state.
9. An alarm-clock comprising a system as claimed in claim 5 .
