Abstract: An encrypted rolling code, a plurality of differing data bit order patterns, and a plurality of differing data inversion patterns are provided. Based on the encrypted rolling code, patterns are selected from one or more of the plurality of differing data bit order patterns and the plurality of differing data inversion patterns. At least a part of the encrypted rolling code is transmitted to a movable barrier operator using the selected patterns as transmission characteristics.

Abstract: 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.

Abstract: A memory life extension system and method is provided for managing operation of rewritable memory used to store a monotonically increasing sequence of multiple-byte binary values in a set of one or more memory locations in the rewritable memory. A first value is read in from a set of one or more memory locations. On detection of an instruction to store an incremented value, the incremented value is permuted by applying an encoding, in which a value of a least significant bit changes only on every second increment, to two least significant bits of the incremented value. On overflow of a least significant byte as a result of the increment, a cyclic byte-wise shift is applied to the incremented value. The permuted incremented value is then stored in the one or more memory locations.

Abstract: A wireless communication system for a vehicle has a portable device that transmits a wireless signal and a vehicle-mounted device that receives the wireless signal from the portable device. Each time a switch in the portable device is turned on, the portable device updates a portable device rolling code and transmits a wireless signal including the portable device rolling code. The vehicle-mounted device receives the wireless signal through a receiver and authenticates the portable device through comparison between the portable device rolling code included in the wireless signal and the vehicle rolling code. The vehicle-mounted device locks or unlocks the vehicle door if the portable device is authenticated. When the wireless signal is received through the receiver after the most recent locking or unlocking of the vehicle door has been carried out using the mechanical key, the vehicle-mounted device locks or unlocks the vehicle door if the switch is turned on for n (n is an integral number greater than or equal to 2) times or more.

Abstract: A rolling code transmitter is useful in a security system for providing secure encrypted RF transmission comprising an interleaved trinary bit fixed code and rolling code. To provide even greater security, the transmitter is limited in the number of times it may perform a resynchronization procedure. A receiver demodulates the encrypted RF transmission and recovers the fixed code and rolling code. Upon comparison of the fixed and rolling codes with stored codes and determining that the signal has emanated from an authorized transmitter, a signal is generated to actuate an electric motor to open or close a movable barrier.

Abstract: A method for training a trainable transmitter in a vehicle that includes receiving a request to enter a training mode of the trainable transmitter from a user, beginning a training mode of the trainable transmitter, receiving a control signal from an original transmitter associated with a remote control system, detecting a frequency and control data of the control signal. The method further includes determining if the control signal is a fixed code signal or a rolling code signal. If the control signal is a fixed code signal, storing the detected frequency and control data. If the control signal is a rolling code signal, comparing the detected control signal frequency to a plurality of predetermined frequencies and based on the comparison, shifting the detected frequency to match one of the predetermined frequencies.

Abstract: An all-trinary rolling code method and system which allow a barrier opener to generate and transmit trinary rolling codes without entering or storing any rolling code values as binary words includes obtaining a stored trinary counter value upon a transmitter being actuated to remotely control a barrier. A trinary function void of trinary to binary or binary to trinary conversions is used to transform the trinary counter value to a trinary rolling code output such that the trinary rolling code output represents a trinary value that would be produced if the trinary counter value were converted to binary, mirrored, had its highest ordered bit set to zero after being mirrored, and converted back to trinary. The trinary rolling code output is combined with a stored trinary transmitter identification value to generate a trinary word. The transmitter transmits the trinary word for receipt by a receiver associated with the barrier.
