Digital clocks can be used to display current time, set alarms, and play music. Some digital clocks include a display incorporating a backlight or other light-emitting technology to allow the display to be read in an environment with a low ambient light level.
Aspects and implementations of the present disclosure are directed to systems and methods for dimming an alarm clock with three displays. An alarm clock can include three displays each positioned on a different side of the alarm clock to allow the alarm clock to be read from different vantage points. For example, in some implementations, an alarm clock can include a front display, a right side display, and a left side display. As a result, a person can read the current time from a wide range of perspectives, without the need for a direct line of sight to the front display. In some implementations, each of the three displays can show the same information, such as the current time. In some other implementations, the front display can serve as a primary display and may include additional information, such as the time for which an alarm is set, and the right and left side displays may show only a subset of the information shown on the front display.
In some implementations, each of the three displays can be a light emitting diode (LED) display, so that each display can be read in the dark. In some other implementations, each display can be a liquid crystal display (LCD) including a backlight to allow the displays to be read in the dark. Each display can have multiple brightness settings. For example, each display may have 2, 3, 4, or more different brightness settings, and a user can adjust the brightness of each display based on ambient light levels and user preferences. Each display may have a respective dimming button or other input device to allow a user to select a desired brightness level. In some implementations, the dimming button for the front display can serve as a master dimming button by controlling the brightness of all three of the displays. The dimming buttons for each of the right side display and the left side display can be configured to control only the brightness level of their respective display. Thus, pressing the dimming button for the right side display can cause the brightness of the right side display to cycle through each of its available brightness levels without adjusting the brightness of either the front display or the left side display. Similarly, pressing the dimming button for the left side display can cause the brightness of the left side display to cycle through each of its available brightness levels without adjusting the brightness of either the front display or the right side display. Pressing the dimming button for the front display can cause the brightness of the front display, the right side display, and the left side display to all cycle through the available brightness levels simultaneously.
In one aspect, the disclosure is directed to a multi-display clock. The multi-display clock can include a front display on a front face of a housing of a clock to display a time, a left side display to display the time on a left face of the housing positioned between about 30 degrees to about 120 degrees to the left of an orientation of the front display, and a right side display to display the time on a right face of the housing positioned between about 30 degrees to about 120 degrees to the right of the orientation of the front display. The multi-display clock can include a front dimming input device configured to receive input to control dimming of each of the front display, the left side display, and the right side display. The multi-display clock can include a left dimming input device configured to receive input to control dimming of the left side display. The multi-display clock can include a right dimming input device configured to receive input to control dimming of the right side display. The multi-display clock also can include a controller configured to adjust a brightness level of each of the front display, the left side display, and the right side display, responsive to receiving an input signal from at least one of the front dimming input device, the left dimming input device or the right dimming input device.
In some implementations, at least one of the front display, the left side display, and the right side display can include a light-emitting diode (LED) display. The controller can be further configured to adjust a light output associated with the LEDs of the LED display, responsive to receiving the input signal from the front dimming input device. In some other implementations, at least one of the front display, the left side display, and the right side display can include a liquid crystal display (LCD) and a backlight. The controller can be further configured to adjust a light output associated with the backlight of the LCD, responsive to receiving the input signal from the front dimming input device. In some implementations, the controller can be further configured to adjust a brightness level of only the left side display, responsive to receiving an input signal from the left side dimming input device, and to adjust a brightness level of only the right side display, responsive to receiving an input signal from the right side dimming input device.
In some implementations, each of the front display, the left side display, and the right side display is configured to display information at a plurality of brightness levels. The controller can be further configured to toggle through the brightness levels of the left side display in order from least bright to most bright, responsive to receiving the input signal from the left side dimming input device. The controller also can be configured to toggle through the brightness levels of the right side display in order from least bright to most bright, responsive to receiving the input signal from the right side dimming input device. The controller also can be configured to toggle through the brightness levels of the front display, the left side display, and the right side display in order from least bright to most bright, responsive to receiving the input signal from the front dimming input device.
In some other implementations, each of the front display, the left side display, and the right side display can be configured to display information at a plurality of brightness levels. The controller can be further configured to toggle through the brightness levels of the left side display in order from most bright to least bright, responsive to receiving the input signal from the left side dimming input device. The controller also can be configured to toggle through the brightness levels of the right side display in order from most bright to least bright, responsive to receiving the input signal from the right side dimming input device. The controller also can be configured to toggle through the brightness levels of the front display, the left side display, and the right side display in order from most bright to least bright, responsive to receiving the input signal from the front dimming input device.
In some implementations, the controller can be further configured to cause each of the front display, the left side display, and the right side display to display first information, and to cause the front display to concurrently display second information along with the first information. The second information can be different from the first information. In some implementations, the first information can include a current time. In some implementations, the second information can include a time for which an alarm is set. The controller can be further configured to cause the multi-display clock to sound the alarm when the current time matches the time for which the alarm is set. In some implementations, the multi-display clock also can include an alarm adjust input device configured to receive input to control the time for which the alarm is set. The controller can be further configured to adjust the time for which the alarm is set, responsive to receiving an input signal from the alarm adjustment input device.
In some implementations, the multi-display clock can include at least one universal serial bus (USB) port communicatively coupled to the controller. In some implementations, the front face of the housing further comprises a substantially transparent cover positioned over the front display. In some implementations, at least one of the left face of the housing and the right face of the housing can include a substantially opaque portion. At least one of the left side display and the right side display can be configured to be visible through the substantially opaque portion of the housing.
In another aspect, the disclosure is directed to a method for using a multi-display clock. The method can include providing a multi-display clock including a front display on a front face of a housing of a clock to display a time, a left side display to display the time on a left face of the housing positioned between about 30 degrees to about 120 degrees to the left of an orientation of the front display, and a right side display to display the time on a right face of the housing positioned between about 30 degrees to about 120 degrees to the right of the orientation of the front display. The multi-display clock also can include a front dimming input device configured to receive input to control dimming of each of the front display, the left side display, and the right side display. The multi-display clock also can include a left dimming input device configured to receive input to control dimming of the left side display. The multi-display clock also can include a right dimming input device configured to receive input to control dimming of the right side display. The method can include receiving, by a controller of the multi-display clock, an input signal from one of the front dimming input device, the left dimming input device, and the right input dimming device. The method also can include adjusting, by the controller, a brightness level of at least one of the front display, the left side display, and the right side display of the multi-display clock, responsive to receiving the input signal.
In some implementations, at least one of the front display, the left side display, and the right side display can include a light-emitting diode (LED) display. The method can further include adjusting, by the controller, a light output associated with the LEDs of the LED display, responsive to receiving the input signal from the front dimming input device.

The method can further include adjusting, by the controller, a light output associated with the backlight of the LCD, responsive to receiving the input signal from the front dimming input device.
In some implementations, the method can include receiving, by the controller, the input signal from the left side dimming input device, and adjusting, by the controller, a brightness level of only the left side display, responsive to receiving the input signal from the left side dimming input device. In some implementations, the method can include receiving, by the controller, the input signal from the right side dimming input device.

Aspects and implementations of the present disclosure are directed to systems and methods for dimming an alarm clock with three displays.
The front display 102a is larger and displays more information than either of the left side display 102b or the right side display 102c. For example, while all of the displays 102 show the current time, the front display 102a additionally includes the time for which an alarm is set. In some implementations, the front display 102a may be considered as the primary display of the alarm clock 100, and the left side display 102b and right side display 102c may be considered as secondary displays. In general, the front display 102a, the left side display 102b, and the right side display 102c may all be configured to display first information, such as the current time as shown in
The displays 102 include LEDs positioned against a dark background, allowing the displays 102 to be read in low light conditions. In some other implementations, the displays 102 can include LCD displays having respective backlights to make the displays 102 visible in low light conditions. The brightness of each display 102 can be adjustable. For example, the brightness of the displays 102 can be reduced by reducing the amount of current passing through the LEDs that form the displays 102. In some implementations, a pulse width modulation (PWM) scheme can be used to control the brightness of the displays 102. For example, a voltage applied to a respective backlight associated with each of the displays 102 can be represented by a square wave having an adjustable duty cycle. In some implementations, the duty cycle of the voltage applied to one of the displays 102 can be increased in order to increase the brightness of the display. The cycle can be, for example, about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 90%, or about 100%, depending on the desired brightness level. In some implementations, each display may have two, three, four, five, or more brightness settings.
The components of the alarm clock 100 are positioned within a housing. Portions of the housing, such as those that are positioned over the left side display 102b and the right side display 102c, are substantially opaque. Thus, in some implementations, the information displayed by the left side display 102b and the right side display 102c may be obscured when the left side display 102b and the right side display 102c are below a certain brightness level. However, with a sufficient brightness level, the information displayed by the left side display 102b and the right side display 102c can be seen through the opaque portions of the housing, as illustrated in
In some implementations, the brightness of each display 102 may be individually adjustable. For example, the front display 102a could be set to a first brightness level, the left side display 102b could be set to a second brightness level, and the right side display 102c could be set to a third brightness level. In some implementations, the brightness of each display 102 can be adjusted using the respective dimming buttons 104. For example, pressing the front dimming button 104a can adjust the brightness of the front display 102a, pressing the left dimming button 104b can adjust the brightness of the left side display 102b, and pressing the right dimming button 104c can adjust the brightness of the right side display 102c. In some implementations, pressing one of the dimming buttons 104 can cause brightness of the corresponding display 102 to change to a different level. In some implementations, the brightness level for a display 102 can be toggled in order from least bright to most bright by pressing the corresponding dimming button 104. For example, a display 102 may initially start in its brightest state. Pressing the corresponding dimming button 104 can cause the brightness of the display 102 to decrease to the second brightest state. Similarly, a subsequent press of the button 104 can increase the brightness of the display 102 to decrease to the third brightest state, and so on. When the display 102 is in its least bright state, pressing the button 102 can cause the display 102 to return to its original brightness. In some implementations, the display 102 may initially start in its least bright state, and pressing the corresponding button 104 can cause the display 102 to increase in brightness.
In some implementations, pressing one of the buttons 104 can affect only the brightness of its corresponding display 102. For example, the left dimming button 104b can be used to adjust the brightness of the left side display 102b without changing the brightness of the front display 102a or the right side display 102c. Similarly, the right dimming button 104c can be used to adjust the brightness of the right side display 102c without changing the brightness of the front display 102a or the left side display 102b. In some implementations, the front dimming button 104a can serve as a master dimming button, by simultaneously adjusting the brightness of the front display 102a, the left side display 102b, and the right side display 102c. For example, the brightness of the front display 102a can be set using the front dimming button 104a in a manner similar to that described above. However, the front button 104a also can simultaneously adjust the brightness of the left side display 102b and the right side display 102c to match the brightness of the front display 102a. Thus, pressing the front dimming button 102a may cause all of the displays 102 to transition to the same brightness level. Subsequent presses of the front dimming button 104a can cause all of the displays 102 to transition to the next available brightness. In order to adjust the brightness of the left side display 102b or the right side display 102c independently, the respective dimming buttons (i.e., the left dimming button 104b or the right dimming button 104c) can be used as described above.
It should be understood that the general shape of the alarm clock 100 shown in
In some implementations, the controller 200 can be general purpose processor. In some other implementations, the controller 200 can be an application-specific integrated circuit (ASIC) or a field programmable gate array (FPGA). In some implementations, the controller 200 may be implemented as software, hardware, or a combination of software and hardware.
The signals transmitted to the controller 200 can correspond to user interaction with the dimming buttons 104. For example, the controller 200 can be configured to receive an indication from each dimming button 104 when a respective button press occurs. The signals transmitted to the displays 102 from the controller 200 can be control signals configured to adjust the brightness of each respective display 102. For example, in some implementations, the controller 200 can send a control signal to a display 102 that causes the display 102 to change its brightness level by applying a different amount of current to the LEDs associated with the display 102. In some implementations, the controller 200 can generate control signals to be sent to the displays 102 based at least in part on the signals it receives from the dimming buttons 104, thereby allowing a user to adjust the brightness of the displays 102 by pressing the buttons 104, as discussed above. In some implementations, the controller 200 may include more or fewer inputs and outputs than are shown in
In the Right Dimming State 260, the controller adjusts the brightness of the only the right side display, while the front display and the left side display are maintained at their current brightness levels. For example, in the Right Dimming State 260, the controller 200 can cause the right side display to transition to the next brightness level (e.g., the level that is one level above or below the current brightness level), but does not cause either of the front display or the left side display to change their brightness levels. Thus, a user can adjust the brightness level of the right side display independently of the brightness levels of the front display and the left side display by pressing the right dimming button. The controller 200 remains in the Right Dimming State 260 until it detects that a user has pressed the front dimming button, the right dimming button, or the left dimming button. If the controller 200 detects that a user has pressed the right dimming button a second time, the controller loops back to the Right Dimming State 260, in which the operations discussed above are repeated, by causing the right side display to transition to the next brightness level. The controller 200 transitions from the Right Dimming State 260 to the Master Dimming State 255 in response to detecting that a user has pressed the front dimming button, and transitions from the Right Dimming State 260 to the Left Dimming State 265 in response to detecting that a user has pressed the left dimming button.
In the Left Dimming State 265, the controller adjusts the brightness of the only the left side display, while the front display and the right side display are maintained at their current brightness levels. For example, in the Left Dimming State 265, the controller 200 can cause the left side display to transition to the next brightness level (e.g., the level that is one level above or below the current brightness level), but does not cause either of the front display or the right side display to change their brightness levels. Thus, a user can adjust the brightness level of the left side display independently of the brightness levels of the front display and the right side display by pressing the left dimming button. The controller 200 remains in the Left Dimming State 265 until it detects that a user has pressed the front dimming button, the right dimming button, or the left dimming button. If the controller 200 detects that a user has pressed the left dimming button a second time, the controller loops back to the Left Dimming State 265, in which the operations discussed above are repeated, by causing only the left side display to transition to the next brightness level. The controller 200 transitions from the Left Dimming State 265 to the Master Dimming State 255 in response to detecting that a user has pressed the front dimming button, and transitions from the Left Dimming State 265 to the Right Dimming State 260 in response to detecting that a user has pressed the right dimming button.
