Electronic systems are provided for secure actuation of a remote device such as a moveable barrier operator. The systems address the man in the middle problem of persons intercepting and duplicating radio frequency signals from a control device by introducing timing parameters into a bidirectional communication sequence between at least two devices.

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.

A method is provided for controlling access to a target device. The method comprises receiving, by the target device, primary input from a user or user device, wherein the primary input matches a predetermined input stored by the target device and authorizes the user or user device to access the target device. The method further comprises storing, by the target device, one or more wireless secondary signals that are detected by the target device during a time period in which the primary input is received. Still further, the method comprises allowing access to the target device in response to receiving the primary input, and then allowing access to the target device in response to subsequently receiving at least one of the one or more wireless secondary signals matching one or more of the stored wireless secondary signals in the absence of receiving the primary input.

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.

In one aspect, a universal receiver is provided for being operably coupled to a movable barrier operator. The universal receiver includes at least one radio antenna adapted to receive signals transmitted at different frequencies and a controller operably coupled to the at least one radio antenna. The controller is adapted to determine a code of a signal received by the at least one radio antenna at any one of the different frequencies. The controller being further adapted to learn the code in response to a user-independent learning condition being met.

A system for installation in a vehicle and for controlling a remote device includes a trainable transceiver and a remote button module. The trainable transceiver base station configured to be mounted in the vehicle at a first location and the remote button module separated from the base station and configured to be mounted in the vehicle at a second location. The remote button module is configured to wirelessly transmit a command signal to the base station in response to receiving a user input at a user input device, and the base station responds to receiving the command signal by transmitting an activation signal to the remote device, wherein the activation signal is formatted to control the remote device.
