Provided is an in-store dual-mode communication system in which shelves are disposed within a commercial space. A server is coupled to the Internet and/or a wide-area network and is configured to send and receive communications. Also provided are light-based messaging units that are located on and/or attached to such shelves, each: 1) having a light source, 2) receiving a communication from the server, and 3) in response to receipt of such communication, turning the light source on and off so as to broadcast a digital message that was included within such communication, as a binary-encoded digital signal corresponding to on/off states of the light source. A user device: (i) receives, via its light sensor, and then decodes the binary-encoded digital signal from a light-based messaging unit in order to obtain the digital message that corresponds to it; and also (ii) communicates with the server via its wireless interface.

A controller for a door operator including a processor, a first actuator, and a transmitter, and associated method. The method may include inverting bit positions of a rolling code, dividing the inverted code by a predetermined number, converting the divided inverted code to base 9 coefficients, and substituting an output nibble for each base 9 coefficient in the divided converted code. The transmitter may be configured to transmit the substituted output nibble responsive to actuation of the first actuator.

Provided is a messaging system that includes: messaging units disposed in different locations within a commercial space, each including a light-emitting diode (LED); a messaging/modulation controller coupled to the LED and configured to turn the LED on and off so as to broadcast a digital message as a binary-encoded digital signal corresponding to on/off states of the LED; and a user interface, coupled to the messaging/modulation controller, that permits a user to create schedules that specify how and when specified messages are to be broadcast by such messaging units. Different ones of the messaging units are configured to broadcast different digital messages, including substantive content that is different from what is broadcast by other ones of the messaging units, in accordance with the schedules input through the user interface.

Systems and methods for controlling a moving barrier responsive to a transmission by a barrier operator controller comprising a plurality of 4-bit output nibbles generated from a 32 bit rolling code. The bit positions of the rolling code are inverted, divided by 16, converted to four bit base 9 coefficients, each four bit base 9 coefficients is substituted with a corresponding 4-bit output nibble. Receipt of the plurality of 4-bit output nibbles causes a barrier operator to actuate a motor connected to the moving barrier.

Provided is a messaging system that includes: messaging units disposed in different locations within a commercial space, each including a light-emitting diode (LED); a messaging/modulation controller coupled to the LED and configured to turn the LED on and off so as to broadcast a digital message as a binary-encoded digital signal corresponding to on/off states of the LED; and a user interface, coupled to the messaging/modulation controller, that permits a user to create schedules that specify how and when specified messages are to be broadcast by such messaging units. Different ones of the messaging units are configured to broadcast different digital messages, including substantive content that is different from what is broadcast by other ones of the messaging units, in accordance with the schedules input through the user interface.

Disclosed are an apparatus and a method for controlling unlocking a door of an automobile includes a fob key having a door unlock input unit manipulated by a user and transmitting a door unlock signal, and a controller provided in an automobile and configured to unlock the door of the automobile when a first door unlock signal is received before the preset period of time elapses or when a second door unlock signal is received after the preset period of time elapses, whereby a door of the automobile is not allowed to be unlocked in the case where a hacking tool intercepts the door unlock signal from the fob key and transmits the same to the controller of the automobile after the preset period of time elapses.

An application method of a Bluetooth low-energy electronic lock based on built-in offline pairing passwords, an interactive unlocking method of a Bluetooth electronic lock, and an electronic lock system are provided, wherein data propagation of some public keys or public addresses is carried out through a scanning response packet of a broadcast packet, the mobile phone APPs run in a Bluetooth server mode, the Bluetooth electronic lock works in a Bluetooth client mode, the Bluetooth electronic lock periodically sends a broadcast packet of a random address, and the Bluetooth electronic lock has a set of temporary door-opening passwords of random algorithm built in after manufacture; and during the initialization process, the Bluetooth electronic lock uploads the built-in temporary door-opening password set, with the random algorithm, through the relational data of application services and the public address of the Bluetooth electronic lock.

The systems and methods provided herein use a rolling voice identifier in a multi-factor authentication system to avoid the security problems present in prior voice activated control systems. By implementing a rolling voice identifier in an access control platform, users may no longer need to be concerned with being overheard or recorded when providing voice authentication commands to an access control platform because the rolling voice identifier that the user will be prompted to speak will be specific to the particular instance of control of an access control platform. An access control platform is a platform that controls operation of a movable barrier by, for example, controlling the state of a movable barrier using a remote control. An access control platform may cause a movable barrier to become opened, closed, locked, or unlocked to permit or prevent access to a physical space by a physical object.

Provided are, among other things, systems, methods and techniques for light-based communication. One representative embodiment includes: messaging units disposed at different locations within a space, each including at least one light source (e.g., light-emitting diode or LED); at least one messaging/modulation controller coupled to the light sources and configured to turn the light sources on and off so as to broadcast input digital messages; a central server coupled to the messaging/modulation controller(s) and configured to selectively provide messages to the messaging/modulation controller(s) for broadcast by different messaging units; and an associate device coupled to the central server and configured to: (a) display a user interface for manually inputting information about individuals within the space and (b) provide such information to the central server, where the central server selects messages to be broadcast by the messaging units based on the information received from the associate device.

An internet-connected garage door control system is disclosed that includes a garage door opener for opening and closing a garage door in response to signals received through the internet, and an in-vehicle remote garage door opener integrated into a vehicle for transmitting the signals through the internet to the garage door opener. The in-vehicle remote garage door opener includes an interface configured to communicate with an internet-connected device, a trainable RF transceiver for transmitting an RF signal to the garage door opener, a user-actuated input, an interface configured to communicate with an internet-connected device, and a controller, wherein, upon actuation of the user-actuated input, the controller is configured to at least one of (a) request a signal to be transmitted by the internet-connected device through the internet to the garage door opener, and (b) cause the trainable RF transceiver to transmit the RF signal to the garage door opener.
