FIELD OF THE INVENTION
• The present invention relates generally to the field of alarm clocks, and more particularly, to an alarm clock with a universal infrared remote home device controller.[0002]
BACKGROUND OF THE INVENTION
• Alarm clocks have been used for a long time to awaken sleepers, in particular to help them begin their work days. Alarm clocks coupled with radio functions have been used to awaken people more gently, using music from a favorite radio station. However, the music being played by the radio station may be sleep-inducing, and thus the alarm function may be frustrated. The snooze function may aid in alleviating the problem of waking the sleeper, but sound sleepers may inactive both the clock alarm and the snooze alarm, resulting in the sleeper's oversleeping.[0003]
• Where the individual has home entertainment devices that he wishes to enjoy until a predetermined bedtime, he would find it beneficial to have a preset time for inactivation of the selected home entertainment device or devices so that he could sleep more comfortably during his normal sleeping time. Though the alarm clock serves as a wake up assistant for most people, such a device should provide further capabilities for remote home entertainment device management to facilitate everyday living.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
• The present invention provides an electronically-operated alarm clock that includes infrared remote control management for a plurality of home devices. The alarm clock typically includes a microprocessor, a display (such as an LED or LCD display), a speaker, an AM/FM radio tuner, clock setup circuitry including an alarm setup and activate circuitry, a programmable universal infrared remote control for at least one device that includes circuitry to activate the remote home device/devices during alarm activation. The Alarm Clock with Remote Control Function, denoted hereafter as Alarm Clock Remote, is an alarm clock with a universal infrared remote controller. The Alarm Clock Remote can function as a universal remote control for one or more remote devices, and also as an alarm clock that can turn on/off the internal alarm and/or radio. The invention can turn on/off at least one specified remote home device such as a television (TV), a video cassette recorder (VCR), an electronic device tuner, a compact disk (CD) player, a video compact disk (VCD) player, a digital video/versatile disk (DVD) player and/or any other home devices remote from the alarm clock, where the home device may accept input from an infrared remote control.[0016]
• FIG. 1 is one embodiment of a flow diagram of steps of an alarm ON handling routine in accordance with the present invention. First, the alarm is switched ON[0017]102. Then, the microprocessor routine checks to see if the alarm flag is in anON position104. Where the alarm flag indicates that the alarm is ON, the microprocessor routine checks to determine whether the buzzer/ringing alarm flag is set to ON106. Where the buzzer/ringing alarm flag is set to ON, the microprocessor turns on the buzzer/alarm108, and the routine returns120 to a ready position wherein the routine start may be triggered102. Where the buzzer/ringing alarm flag fails to be set to ON, the microprocessor determines whether a radio alarm flag is set to ON110. Where the radio alarm flag is set to ON, the microprocessor turns the radio on112, then the routine returns120 to a ready position wherein the routine start may be triggered102. Where the radio alarm flag fails to be ON, the remote alarm has been set to ON113. The microprocessor picks up/processes114 a current device set code that is input by the four buttons: ±channel and ±volume and uses a look-up table116 to determine which remote device is to be activated. Upon determining the remote device to be activated, the microprocessor sends aninfrared signal118 to the selected remote device to activate it and then the routine returns120 to a ready position wherein the routine start may be triggered102.
• FIG. 2 is one embodiment of a clock checking routine which runs every minute in accordance with the present invention. The microprocessor utilizes the internal real-[0018]time clock update202 to determine whether to activate the alarm. An update display is shown204 on the display unit. The microprocessor checks to see whether the alarm is set to ON206. Where the alarm fails to be set to ON, the microprocessor proceeds to return212 to running the internal real-time clock update again. Where the alarm is set to ON, the microprocessor determines whether the current time is the same time as the time set for the alarm to be activated208. Where the current time fails to be the same time as the time set for the alarm to be activated, the microprocessor proceeds to return212 to running the internal real-time clock update again. Where the current time is the time set for the alarm to be activated, the microprocessor sets the alarm flag to ON210, which activates the alarm/buzzer.
• FIG. 3 is a schematic representation of one embodiment of a control switching system with alarm setup and activate circuitry and a programmable universal infrared remote control for at least one remote device with circuitry to activate the remote home device/devices during alarm activation, a display and controlled elements that are coupled to a microprocessor for the alarm clock. The microprocessor unit (MCU)[0019]302 is coupled to adisplay304, which may, for example, be an LED display. A plurality ofswitches312, which may, for example include an alarm switch SW1, a time switch SW2, a sleep switch SW3, a snooze switch SW4, an AM/FM radio switch SW5, a remote power switch SW6, a remote sleep switch SW7, an hour switch SW8, a minute switch SW9, a volume increment (V+) switch SW10, a volume decrement (V−) switch SW11, a channel increment (Ch+) switch SW12, a channel decrement (Ch−) switch SW13, a first switch A for a first selectable remote device SW14, a second switch B for a second selectable remote device SW15, and a third switch C for a third selectable remote device SW16. Clearly, many other configurations of switches may be used. The desired switches may be selected to activate/deactivate or increment/decrement settings and devices as selected. Each of the plurality of switches is configured to have an input port to receive signals from the MCU and an output port to provide output signals to theMCU302. In accordance with the switch activated, theMCU302 sends ON/OFF control signals to the AM/FM radio306, the remoteIR diode circuitry308 or the internal buzzer/alarm310.
• FIG. 4 is a schematic representation of one embodiment of an infrared[0020]diode driving circuitry308 in accordance with the present invention. Upon receiving an ON/OFF control signal from theMCU302, the remote IR diode driving circuitry activates theIR1402,IR2404 and/orIR3406 LEDs in accordance with a predetermined scheme that sends an infrared signal to the remote device selected via the four buttons: Channel+ (channel increment button), Channel− (channel decrement button), Volume+ (volume increment button) and Volume− (volume decrement button).
• FIG. 5 is a schematic illustration of one embodiment of an alarm clock with a remote function in accordance with the present invention. The[0021]alarm clock500 includes a time/alarm button502 that is used to toggle between the time and alarm mode of operation. When the time/alarm button502 is first pressed, the device enters the alarm mode. As is known in the art, thehour button504 andminute button506 are then used for setting the time for activation of the alarm, whereupon thedisplay526 shows the alarm time. In one embodiment, the alarm may include an internal buzzer or ringing alarm, AM/FM radio activation circuitry and at least one remote device alarm that may be activated as described below. The time/alarm button502 is used to toggle the device back and forth from a current time mode to the alarm and sleep/off mode. In the time mode, thedisplay526 shows the current time in hours and minutes, which are adjustable using thehour button504 and theminute button506. In the alarm mode, the alarm activation time, radio activation time and remote device activation time may be set by the hour and minute buttons, sequentially as set forth in greater particularity below. In an alternate embodiment, upon selection of the alarm mode, the alarm activation time may be set, the time/alarm button502 may be depressed to advance to the radio activation mode in which the radio activation time may be set, the time/alarm button502 may be depressed again to advance to a first remote device mode in which the first remote device activation time may be set, and so forth for a predetermined number of remote device mode activations. Where desired, as shown in FIG. 5, there may be a plurality ofLEDs522, for example, aligned immediately above or next to a name of each remote device, wherein the LED for the remote device being activated or deactivated lights up.
• The[0022]hour button504 is used to change the hour setting of the current time, alarm time and/or sleep/off time. When thehour button504 is pressed, the current hour setting is advanced by one hour. If thehour button504 is pressed down for more than a first predetermined time, e.g., two seconds, a fast mode is entered, and the hour setting is advanced at a first predetermined rate, e.g., a rate of one hour per second.
• When the[0023]minute button506 is pressed, the minute setting of the current time, alarm time or sleep/off time may be changed, i.e., the time in minutes will be advanced one minute from the current setting. If theminute button506 is pressed down for more than a second predetermined time, e.g., two seconds, a fast mode is entered, and the minute setting will be advanced at a predetermined rate, e.g., a rate of four minutes per second.
• When the sleep/off[0024]button508 is pressed, the sleep/off setup mode is entered. Thedisplay526 will show the sleep/off time, and thehour button504 andminute button506 will be used for sleep/off time setup. When the sleep/offbutton508 is pressed again, it will toggle between the sleep/off mode being ON and OFF. The process of setting the sleep/off settings follows the same scheme as shown for the alarm routine shown in FIG. 1, except that, rather than setting the alarm activation, the sleep/off activation is being set.
• When the[0025]snooze button524 is ON, thesnooze button524 stops the alarm ringer/buzzer for a predetermined time. In one embodiment, thesnooze button524 turns off the alarm ringer/buzzer for 10 minutes, after which time the alarm buzzer and/or radio are again activated. Clearly, the predetermined time for snoozing may the manufacturer select any convenient time.
• For convenience, the volume adjust[0026]knob532 may be used to adjust the volume for either the alarm buzzer volume or the radio volume, where the alarm buzzer or radio may be selected using the switch530 next to the volume adjustknob532. The AM/FM selection switch536 is used to select the AM or FM mode of the radio. The AM/FM tuning knob534 for the radio channel is used to tune to the desired radio channel, as indicated on the AM/FM channels indicator528. Aremote power button510 may be used to turn the power on and off for the remote device. The remote sleep/off button512 may be used to set the TV or other selected remote device so that the power is shut off for the selected remote device at a preselected sleep time. In addition, aChannel+ button514 may be used to advance the channel setting for the TV (or go to a next musical selection on a CD) and a Channel−button516 may be used to decrement a channel setting for the TV (or decrement to a prior musical selection on a CD).
• When the user desires to power up a remote device, pressing the remote power and remote sleep/off buttons simultaneously will activate a remote device setup mode, or the remote device may be activated using the scheme shown in FIG. 1, which is described with more particularity below. In the remote device setup mode, the[0027]Channel+ button514, the Channel−button516, theVolume+ button518 and the Volume−button520 may be used for remote device selection. A combination of the Channel+, Channel−, Volume+ and Volume− buttons will form a unique code for each remote device. The remote device selection is completed by the input of the fourth code entry. Then the microprocessor will use the unique code to look up each function key code for the remote control device.
• When the time/[0028]alarm button502 is used to set the alarm to the ON mode, the microprocessor checks the current time with the alarm time. Where the current time is equal to the alarm setup time, the alarm is triggered. If the alarm mode is set to an internal alarm, i.e., a buzzer and/or radio, the internal trigger circuitry for the buzzer and/or radio will be activated. The internal alarm can be turned off by pressing the snooze button or the sleep/off button. If the alarm mode is set to activate the remote device, the remote device will be turned on by sending an infrared (IR) signal that simulates the power button, thus activating the remote device. When the remote device has been activated by the IR signal, the remote device can be turned off manually or by pressing the remote sleep/off button to activate the sleep/off process and using the hour button and minute button to set the sleep/off time.
• In one embodiment, when a process is activated, an LED next to each button may light up to indicate that the button has activated a process or may be unlit to indicate that the process is inactive.[0029]
• FIG. 6 is a schematic representation of one embodiment of a control switching system having two microcontroller/[0030]microprocessor units602,604 with alarm setup and activate circuitry for controlling at least one remote device. The microcontroller/microprocessor unit (MCU)602, e.g., a radio clock controller, is coupled to adisplay unit606, which may, for example, be an LCD display and apower supply610. A plurality ofswitches608, which may, for example, include a snooze switch SW10, an alarm switch SW11, a time switch SW12, a sleep switch SW13, an hour switch SW14, and/or a minute switch SW15, may also be coupled to theMCU602. Clearly, many other configurations of switches may be used. The desired switches may be selected to activate/deactivate or increment/decrement settings and devices as selected. Each of the plurality of switches is configured to be activated or inactivated by signals from theMCU602. In this embodiment, an output from the alarm/radio controller MCU602 is coupled to an input of the remote control MCU604 (universal remote controller). Where the user sets up the alarm mode as a remote alarm, theremote control MCU604 is activated, and theremote control MCU604 looks up the preset device and sends out a power signal to activate the selected remote device. Similar to the procedure shown in Figure I, where the remote alarm has been set toON113, the universalremote microcontroller604 determines which remote device is to be activated and sends a signal to the selected remote device to activate it. The universalremote controller604 may also be coupled to apower supply610 and a plurality of switches such as, for example, a power switch900, a volume increment switch (Vol+)901, a volume decrement switch (Vol−)902, a channel increment switch (Ch+)903, a channel decrement switch (CH−)904, and/or a mute switch905, that may be activated by the universalremote controller604.
