(10) FIG. 1 shows an example garage door 10 the opening and closing of which is controlled, at least in part, by a remote control unit 12. The garage door 10 is connected with a garage door opener (not shown) that opens/closes the garage door 10 in a conventional manner, such as with a belt-drive or chain-drive system. The garage door opener is in wireless communication with the remote control unit 12 and is configured to open/close the garage door 10 based on a control signal wirelessly received from the remote control unit 12. For example, the remote control unit 12 could send a wireless command signal to the garage door opener to open/close the garage door 10. A double garage door is shown for purposes of illustration, but the type, size and shape of the garage door 10 that is controlled by the remote control unit 12 could vary depending on the circumstances.

(11) FIGS. 2 and 3 illustrate the example remote control unit 12 with a cover 14 in a closed position and in an open position to reveal a keypad 16, respectively. In the embodiment shown, the cover 14 is pivotally connected to a base housing 18. Although the cover 14 pivots generally about a horizontal axis in the example shown, one skilled in the art should appreciate the cover 14 could pivot about the vertical axis or otherwise be connected to the base housing 18 to aid in weatherproofing. In some embodiments, the cover 14 may be optional, such as if the base housing 18 is weatherproof; in some embodiments, the keypad and/or wireless authentication activation element could be on the base housing 18 and no cover 14 may be provided.

(12) As shown, the remote control unit 12 includes a wireless authentication activation element, which is a touch surface 20 in the embodiment shown that can be used to initiate authentication of the user, such as through wireless communication of an electronic authentication key. The touch surface 20 is shown for purposes of example, but the wireless authentication activation element could be embodied as a touch sensor, proximity sensor, a physical button, a physical switch, a piezo element, inductive element or a resistive element or other element that could be user-selected or detect the user's presence in proximity to the remote control unit 12. Although the touch surface 20 is circular in the example shown, one skilled in the art should appreciate that the touch surface could be any desired shape. In some cases, the touch surface 20 could be a capacitive touch surface in which user-selection of the surface 20 could be detected by the remote control unit 12 to initiate an authentication process. In some embodiments, the remote control unit 12 is configured to perform a wireless authentication process, such as using Bluetooth™ communications (or some other wireless protocol), with a key fob or mobile device to determine whether the user is authenticated. If the user is authenticated based on wireless communications with the user's key fob or wireless device, the remote control unit 12 will transmit a wireless control signal to the garage door opener to open/close the garage door 10.

(13) In the embodiment shown, the remote control unit includes a light communication device 22 that is configured to communicate status information and/or operational information to the user concerning the remote control unit 12 and/or the garage door 10. For example, the light communication device 22 could light up to indicate that the key fob or mobile device of the user is in range of the remote control unit 12. In some cases, the light communication device 22 could change colors and/or have other animations based on operation, such as opening/closing of door. In the example shown, the light communication device 22 has a ring-like shape that surrounds the touch surface 20. However, the light communication device 22 could be any shape depending on the circumstances.

(14) As shown, the cover 14 includes an opening 24 (see FIG. 2) sized to receive the touch surface 20 so that the touch surface 20 is accessible therethrough. With this embodiment, the user would not need to open the cover 14 to open/close the garage door 10. Instead, the user could merely touch the touch surface 20 with a key fob or mobile device in the user's pocket (or bag or other area) to open/close the garage door 10. By touching the touch surface 20, this will cause the remote control unit 12 to initiate communications with the key fob or mobile device for purposes of authentication. If the key fob or mobile device is authenticated, the remote control unit 12 would then transmit a wireless control signal to the garage door opener, which would open/close the garage door 10.

(15) FIG. 3 shows the remote control unit 12 with the cover 14 in the open position, which reveals the keypad 16. With the cover 14 in the open position, the user could either use the touch surface 20 or the keypad 16 for authentication to open/close the garage door 10. The keypad 16 would operate as a conventional keypad in which the user could select an open/close button upon entering a pin code. The remote control unit 12 would determine whether the pin code is valid, and if so, transmit a signal the garage door opener to open/close the garage door 10.

(16) Referring to FIG. 4, there is shown a simplified block diagram showing an embodiment of the remote control unit 12. In this embodiment, the remote control unit 12 includes a power source 26, such as batteries or a hardwired power source, which provides electrical power to electrical components in the remote control unit 12. As shown, the remote control unit 12 includes a controller 28 that is configured to control operation of the remote control unit 12. The controller 28 may be embodied as a single or multi-core processor(s), microcontroller, or other processor or processing/controlling circuit. The controller 28 is electrically connected to a Bluetooth™ unit 30, which is configured to send and receive wireless communications using the Bluetooth™ protocol via a 2.4 GHz antenna 32. Although the Bluetooth™ unit 30 is shown for purposes of example, other protocols could be used to wirelessly authenticate the user.

(17) In the embodiment shown, the controller 28 is electrically connected with a user interface 34. As this example, the user interface 34 includes a touch sensor circuit 36, a keypad circuit 38, an audible unit 40 and LEDs 42. The touch sensor circuit 36 is configured to detect a user touching the touch surface 20. Upon detecting such a touch of the touch surface 20, the touch sensor circuit 36 would provide a signal to the controller 28 indicating that the touch surface 20 has been actuated. The controller 28, in turn, would send a wireless communication with the Bluetooth™ unit 30 to authenticate the user's key fob or mobile device using Bluetooth™ communications. The keypad circuit 38 is configured to provide input received through the keypad 16 to the controller 28 for authentication (or other purposes for which the keypad 16 could be used). In this example, the user interface 34 includes an audible unit 40, which could be configured to generate sounds as desired during operation of the remote control unit 12. The controller 28 could be configured to turn on/off the LEDs 42 as desired, such as for backlighting of the keypad 16, for the light communication device 22, etc.

(18) As shown, the controller 28 is electrically connected to a garage opener transmitter unit 44, which is configured to send and receive wireless communications to the garage door opener via a 300-400 MHz antenna 46 to open/close the garage door 10. Many garage door openers operate in the 300-400 MHz spectrum, which is why the antenna in that spectrum is shown for purposes of example. However, the garage opener transmitter unit could be configured to transmit a control signal to the garage door opener on any frequency as desired.

(19) FIG. 5 is a flow chart showing example operations that could be performed by the remote control unit 12. In this example, the remote control unit 12 is in sleep mode (Block 48) until the touch sensor circuit 36 detects a user-selection of the touch surface 20 (Block 50) or the user enters a pin code on the keypad 16 (Block 52). If the user selects the touch surface 20, the controller 28 initiates a user authentication process (Block 54). In some embodiments, the controller 28 wirelessly receives an electronic authentication code from a key fob or mobile device. The controller 28 determines whether the electronic authentication code is valid (Block 56), and if so, transmits a control signal via the garage opener transmitter unit 44 to the garage door opener to open/close the garage door 10 (Block 58). If the user enters a pin code on the keypad (Block 52), the controller 28 determines whether the code is valid (Block 60). If so, the remote control unit 12 transmits a control signal via the garage opener transmitter unit 44 to the garage door opener to open/close the garage door 10 (Block 62).
