A sound password unlocking method, comprises unlocking procedures: collecting a sound password signal that the user plays and performing the analog to digital conversion (11); Inputting the converted sound password signal to a reference signal input end of an adaptive noise cancellation module; inputting an original signal to an original signal input end of the adaptive noise cancellation module; producing a first output signal in adaptive noise cancellation (12); Calculating the difference between the first output signal and the original signal (13); Comparing the difference between the first output signal and the original signal with a standard difference; determining the sound password is correct if the two difference values are identical and enabling the motor to drive a lock cylinder to open otherwise no unlock operation executed (14). The sound password unlocking method provided by the present invention, based on adaptive noise cancellation is hard to be cracked, which is reliable and safe. The lock could be locked by sound password recognition.

A method of controlling access to an enclosed area having a boundary includes generating a first inaudible audio signal inside the enclosed area, and generating a second signal, each configured to be sensed by a sensing device, wherein the first inaudible audio signal is not capable of penetrating the boundary; determining a state of the enclosed area, based on either the first inaudible audio signal, or the first inaudible audio signal and the second signal, being sensed by the sensing device; and based on the state, generating an instruction to perform access control for the enclosed area.

A system including a reader device and a mobile device having a user credential. The reader device includes an ultrasonic transmitter configured to transmit an identifier, and a wireless transceiver configured to receive information from and transmit information to the mobile device. The identifier is configured to be received by a microphone of the mobile device. The mobile device may determine a position of the mobile device based on the identifier.

A system and method for locating a mobile device relative to a vehicle using mechanical waves and modulation techniques. A high frequency carrier wave that is generally inaudible to humans is modulated with a low frequency baseband signal that provides for accurate localization in order to generate a modulated signal. The modulated signal is a mechanical or pressure wave, as opposed to an electromagnetic (EM) wave, that is transmitted by one or more speaker(s) and is received by one or more microphone(s). In one example, the modulated signal is transmitted from a speaker on the mobile device (e.g., a smart phone) to a number of microphones mounted on the vehicle at specific distances apart, so as to establish multiple localization paths whose differences in phase can be used to determine the location of the mobile device, relative to the vehicle.

Provided is an information processing apparatus including: a locking control unit configured to execute a first process of processes for causing a locking unit to unlock, on the basis of detection of access of a first communication terminal; and a detection unit configured to detect an unlocking request by a user of the first communication terminal. The locking control unit executes a second process of the processes for causing the locking unit to unlock, when the unlocking request is detected and the first process is completed.
