Abstract: The present disclosure provides for a novel method and apparatus for automatically unlocking a vehicle, comprising installing a biometric authentication module located within a door of the vehicle. The authentication module comprises a microcontroller board with NFC capabilities and a relay shield configured to send a signal to a central locking system of the vehicle. The authentication module is adapted to wirelessly connect to a personal data device (“PDD”) that is configured for biometric authentication of a user of the device. When a PDD is placed within NFC communication range of the microcontroller board, the PDD automatically prompts an authentication mechanism to the verify the identity of a user when the PDD is in NFC communication with the authentication module. Upon verifying the identity of the user via biometric authentication while in NFC communication with the PDD, the module automatically sends a signal to unlock the vehicle.

Abstract: A quadrature amplifier comprises first and second amplifiers, each having an input and an output, a signal splitter connected to the inputs of the two amplifiers, a signal combiner connected to the outputs of the two amplifiers, and an impedance transformer connected to the output of the signal combiner. The signal splitter is a ?3 dB hybrid that splits an input signal into two output signals of equal amplitude that are in phase quadrature. The signal combiner is a ?3 dB hybrid that combines the output signals at the outputs of the two amplifiers. Since the output signals are in phase quadrature, the signals are combined to produce an inphase signal. The impedance transformer matches the output signal to an impedance of approximately 50 Ohms. Capacitive and resistive tuning networks connected to the ports of the signal combiner allow for adjustment of the center frequency and impedance of the signal combiner.
