Transceiver/Interface Unit
The system 100 further comprises an interface unit with an interface transceiver 330 (e.g., RF transceiver) (or radio) for handling the wireless communications of the system 100. The interface transceiver 330 of the present invention replaces the standard RF receiver in standard garage door openers. For example, standard garage door openers generally have a receiver for receiving commands from remote wireless modules that can control the operation of the motor. This interface transceiver 330 of the present invention is adapted to send and receive data to the remote device 200 of the present invention, thus is capable of two-way communication with the remote device 200. This two-way communication allows the remote device 200 of the present invention to know the real-time status of the garage door (e.g., up or down).
The interface transceiver 330 may be operatively connected to the motor microprocessor 300 (e.g., microcontroller, e.g., low power microcontroller). In some embodiments, the interface unit (interface transceiver 330, motor microprocessor 300) is installed next to the garage door controller (e.g., a motor unit of the garage door controller). The interface unit may comprise (a) open/close control lines; and (b) a door status inquiry interface.
Remote Device
The system 100 of the present invention further comprises a remote device 200, which functions to send commands to and receive input from the transceiver 330. Generally, the remote device 200 is used inside a vehicle. The remote device 200 both manipulates the garage door (e.g., moving the garage door between the open position and the closed position) and indicates the real-time status of the garage door.
The remote device 200 further comprises a speaker 230 (or vibrator) adapted to emit an alarm sound, which provides a means of alerting a user if the garage door is left open (and the remote device 200 is farther than a predetermined distance from the garage door). The speaker 230 is operatively connected to the remote microprocessor 600. The remote device 200 further comprises an indicator system for indicating the status of the garage door. In some embodiments, the indicator system is a light or series of lights (e.g., “LED” in
In some embodiments, a push button is disposed on the remote device 200 and operatively connected to the remote microprocessor. The push button functions to control the movement of the garage door. The push button can move between a first position to move the garage door to the closed position and a second position to move the garage door to the open position.
If a slider is used as the indicator system, the slider 210 may be used to both indicate the status of the garage door and to manipulate the garage door. The slider 210 may slide between a first position and a second position (and optionally a center position). In some embodiments, the slider 210 is operatively connected to an internal motor 220, which functions to move the slider 210 between the various positions. Generally, the position of the slider 210 reflects the real-time status of the garage door. For example, when the slider 210 is moved to the first position, the garage door is moved to the closed position. When the slider 210 is moved to the second position, the garage door is moved to the open position. In some embodiments, when the garage door is moved to the closed position, the slider 210 is moved to the first position and when the garage door is moved to the open position, the slider 210 is moved to the second position. Referring now to
In some embodiments, when the push button or slider 210 is moved to the first position, the push button or slider 210 sends a first button input signal to the remote microprocessor 600. Upon receipt of the first button input signal, the remote microprocessor 600 sends a first remote transceiver output command to the remote transceiver 630 to cause the remote transceiver to send a first door signal to the interface transceiver 330. Upon receipt of the first door signal, the interface transceiver 330 sends a first motor microprocessor signal to the motor microprocessor 300 whereupon the motor microprocessor 300 sends a first motor output command to the motor unit (and controller) to move the garage door to the closed position.
In some embodiments, when the push button or slider 210 is moved to the second position, the push button or slider 210 sends a second button input signal to the remote microprocessor 600. Upon receipt of the second button input signal, the remote microprocessor 600 sends a second remote transceiver output command to the remote transceiver 630 to cause the remote transceiver to send a second door signal to the interface transceiver 330. Upon receipt of the second door signal, the interface transceiver 330 sends a second motor microprocessor signal to the motor microprocessor 300 whereupon the motor microprocessor 300 sends a second motor output command to the motor unit (and controller) to move the garage door to the open position.
In some embodiments, the remote device 200 comprises a power switch 205 for turning on and off the remote device 200. In some embodiments, the remote device 200 further comprises a light 215 (e.g., incandescent, halogen, light emitting diode, etc.) and a light switch 213.
In some embodiments, the remote device 200 stays in a lower power mode. Power may be obtained via a battery. In some embodiments, the interface unit (e.g., interface transceiver) stays in a lower power listening mode and wakes up only to handle requests from the remote transceiver (e.g., request for door status information, relay the open/close commands sent from the remote device). In some embodiments, an external antenna is used for the interface unit. The interface unit is operatively connected to a power source (e.g., a battery, an electrical outlet via an AC adaptor, etc.).
Alert Mechanism
The system 100 of the present invention alerts a user (e.g., via the speaker 230 emitting the alarm sound, via a vibration system, or a combination thereof) if he/she has left the garage door in the open position, for example after he/she has left the house (e.g., when the remote device 200 moves farther away than predetermined distance). The remote transceiver 630 and the interface transceiver 330 are in communication with each other and are configured to communicate with each other within a range (e.g. predetermined distance). When the remote transceiver fails to detect the interface transceiver 330 (e.g., because the remote device 200 has been moved outside of the range of the transceivers 330), the remote transceiver 630 sends a first alarm input signal to the remote microprocessor 600. Upon receipt of the first alarm input signal, the remote microprocessor 600 recalls the position of garage door (e.g., the position as the remote device left the range of the transceivers). If the garage door was in the open position when the remote device 200 when out of range, the remote microprocessor sends a first alarm output command to the speaker 230 to cause the speaker 230 to emit the alarm sound. The alarm sound alerts the user that the garage door is still in the open position. If the garage door was in the closed position when the remote device 200 when out of range, the remote microprocessor does not send an output command to the speaker 230.
The alarm may be emitted for a certain length of time (e.g., 5 seconds, 10 seconds, 20 seconds, etc.). In some embodiments, the alarm turns off automatically.
The present invention is not limited to a speaker 230 with alarm for alerting the user. For example, a vibration system may be used to alert the user. In some embodiments, the remote device 200 comprises a silence button for silencing the speaker with alarm or vibration system (e.g., either while it's going off, or to prevent it from going off, etc.).
In some embodiments, an indicator light may become illuminated to indicate to the user that the remote device 200 (remote transceiver) has lost communication with the garage door controller and interface unit (interface transceiver).
In some embodiments, signal strength (e.g., of the transceivers) may be modified so as to change the range (e.g., the distance allowed before the alarm sounds). In some embodiments, the signal strength can be adjusted by a control on the garage door controller. This adjusts the distance that the signal can be received by the remote and thus the distance before the alert sounds. This alarm in some embodiments could include either a spoken announcement or a buzzer/alarm sound.
In some embodiments, the range of the transceivers is between about 100 to 200 feet. In some embodiments, the range of the transceivers is between about 200 to 500 feet. In some embodiments, the range of the transceivers is between about 500 to 1000 feet. In some embodiments, the range of the transceivers is between about 1000 to 5000 feet. In some embodiments, the range of the transceivers is between about 5000 feet to 2 miles. In some embodiments, the range of the transceivers is between about 2 to 10 miles.
In some embodiments, this two-way communication mechanism can be accomplished using microprocessor (e.g., microcontrollers) with integrated transceivers or microprocessor (e.g., microcontrollers) with a separate transceiver. In some embodiments, the data format used for communication is developed by the designer, but would include at least, a unique device ID, and the state of the garage door.
In the case where there are multiple remote devices 200, there may be a case where the garage door becomes out of sync with the remote devices 200 (e.g., the push buttons, the sliders 210). To correct for this case, the remote microprocessor 600 and remote transceiver 630 may constantly be monitoring the position of the push button or slider 210 and the state of the garage door. When the remote microprocessor 600 finds that the push button or slider 210 is out of position, the internal motor 220 will in some form reposition the push button or slider 210. In the case of a slider 210, this may be accomplished via the belt 240 connected to the motor 220 and slider 210. In some embodiments, if the user tries to push the slider 210 while the motor is running, it will be allowed to slip. After the motor 220 positions the switch, it disengages so that the user can control the slider 210. This may be accomplished by ensuring that there is sufficient slack in the belt 240 to allow for it to slip on the motor 220. In some embodiments, the motor 220 can be allowed to freely rotate when not powered, or the tension in the belt 240 can physically be released by releasing some of the tension on a belt tensioner. If the user begins to press on the slider 210 before the slider is in the appropriate position, the motor 220 disengages and allows the user to control it.
In some embodiments, the transceivers operate in the 315 MHz ISM band, for example. Software may in some embodiments be developed in C language and be compiled for the microcontrollers (microprocessors) in both the interface unit and the remote device independently. Layered communication software architecture defined interface may ensure reliability. Error detection and retransmission in radio link layer ensures data integrity.
As used herein, the term “about” refers to plus or minus 10% of the referenced number. For example, an embodiment wherein the range of the transceivers is about 100 feet includes a range between 90 and 110 feet.
