Solution Overview
Problem
Users face difficulties in training a new vehicle's built-in wireless control system to activate remote devices like garage door openers, as the original transmitter is often misplaced or not transferable to a new vehicle.
Innovation Solution
A system and method that includes a receiver with increased sensitivity, processing electronics, and a memory to learn and store signal characteristics from a first transmitter, allowing a second transmitter to generate and transmit control signals to activate remote devices, enabling the training of a new vehicle's control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the original handheld transmitter is used for training the built-in control system, then the control system can be trained to activate remote devices, but the transmitter may be misplaced or discarded and cannot be transferred to a new vehicle
Solution Approach 1:
The patent creates a copy of the control signal characteristics from the original transmitter by using a receiver to capture and analyze the signal. The processing electronics extract signal characteristics (frequency, modulation type, protocol) and store them in memory. A second transmitter then reproduces these characteristics to activate the remote device, eliminating the need for the original transmitter.
Solution Approach 2:
The built-in control system acts as an intermediary between the original transmitter and the remote device. The receiver captures signals from the original transmitter, the processing electronics analyze and store the characteristics, and the second transmitter uses these stored characteristics to communicate with the remote device, making the original transmitter unnecessary.
2Measurement precision
If the receiver sensitivity is increased to capture weak signals from distant transmitters, then signal reception improves, but noise and interference may increase
Solution Approach 1:
The patent applies local quality by making the receiver highly sensitive specifically for detecting the frequency and modulation characteristics of training signals, while the processing electronics selectively process only the relevant signal parameters. This targeted approach allows high sensitivity without proportionally increasing noise impact on the entire system.
Solution Approach 2:
The processing electronics analyze the received signal to determine its characteristics and validate whether it matches expected training signal patterns. This feedback mechanism allows the system to distinguish between legitimate training signals and noise/interference, maintaining high receiver sensitivity while filtering out harmful factors through intelligent signal recognition.

AI summary
A system for mounting to a first vehicle and for learning information from a first transmitter configured to be mounted to a second vehicle. The first transmitter is further configured to cause the activation of a remote device by transmitting a first control signal to the remote device. The system includes a receiver and processing electronics coupled to the receiver and configured to increase the sensitivity of the receiver. Increasing the sensitivity of the receiver is based on the receipt of a first command that indicates that the information will be communicated from the first transmitter. The receiver with increased sensitivity is configured to receive the information from the first transmitter. The processing electronics are configured to used the received information to determine signal characteristics. The system further includes a memory coupled to the processing electronics and configured to store the signal characteristics, and a second transmitter coupled to the processing electronics. The second transmitter is configured to receive a second command from the processing electronics to generate and transmit a second control signal based on the stored signal characteristics. The second control signal is transmitted to the remote device to cause the activation of the remote device.
