Abstract

The idea behind this invention is to have several radio frequency (RF) devices installed in the parking lot in a well organized manner. The RF device would receive the signals from the keyless entry devices, amplify those signals and emit them out using RF emitters. The rays emitted by this device would be received by the cars around the device. When the signals are received by the car, the car would beep and indicate its location. The RF signals would also be received by similar devices that are arranged at a particular distance from the first device. Those devices will in turn amplify and emit the RF signals received from the first device. In such a fashion, the entire parking lot will be covered. So a car parked anywhere in the parking lot can be detected

Implementation of location based identification mechanism using radio frequency sensors for vehicles parked in large domains

The implementation makes use of the keyless entry device that is supplied with most cars. It also requires a device with sensors attached to it. The purpose of this device is to receive the signals from the keyless remote entry amplify it and re-emit it for reception by other cars and other receivers.

User activates the keyless entry device like a remote control for the vehicle. The electromagnetic rays from the device will be picked up by the receiver that is installed in the parking area. The receiver amplifies the signal and transmits it. If the vehicle is parked in the vicinity of the signal strength, it activates the receiver in the vehicle to sound alarm.

There are some basic assumptions that are made in this design:
1. Vehicle has a keyless entry system and a device.
2. The sound of the alarm is audible.

The main aspects of this disclosure are the following:
1. Keyless entry device
2. Parking lot with the transmitter and receiver installed.
3. A vehicle that has the audible sound alarm
