摘要:
Wireless communication terminals and methods are disclosed that determine acoustic ranging synchronized to RF communication signals. A communication terminal can include a RF transceiver, a microphone, and a controller. The controller synchronizes a clock in response to known timing characteristics of received RF communication signals. The controller determines an acoustic signal generation time relative to the RF communication signal synchronized clock at which the other communication terminal will generate an acoustic signal. The controller determines an acoustic signal receipt time relative to the RF signal synchronized clock when the acoustic signal from the other communication terminal is detected in the microphone signal. The controller further determines a propagation time of the acoustic signal from the other communication terminal to the microphone based on a difference between the acoustic signal generation time and the acoustic signal receipt time, and determines a range to the other communication terminal in response to the propagation time of the acoustic signal.

A system includes a processing logic and output logic. The processing logic is configured to receive information identifying points of interest, identify at least one of location or distance information from each of the points of interest to the system, and sort the points of interest based on the location or distance information. The output logic is configured to project information identifying the points of interest onto a surface, wherein the projected information is displayed in accordance with the sorting.

Electronic devices and methods are disclosed that adaptively filter a microphone signal responsive to recognition of a targeted speaker's voice. An electronic device can include a microphone, a speaker characterization circuit, an adaptive sound filter circuit, and a speaker recognition circuit. The speaker characterization circuit operates in a training mode to learn characteristics of the targeted speaker's voice component in the microphone signal, and to store the learned characteristics. The adaptive sound filter circuit adaptively filters the microphone signal responsive to a control signal. The speaker recognition circuit uses the learned characteristics to recognize the presence of the targeted speaker's voice in the microphone signal and to regulate the control signal to cause the adaptive sound filter circuit to adapt the filtering to increase the targeted speaker's voice component of the microphone signal relative to other components.
摘要:
A wireless mobile terminal works with an identification server to automatically identify a broadcast program/movie and then identify and connect to a networked media server to receive the identified program/movie therefrom. The terminal generates data that characterizes content of a broadcast program/movie that is send by the terminal and is playing external thereto. The terminal transmits a message that includes the characterization data and a request for identification of a media server from which the broadcast program/movie can be received. The identification server identifies the broadcast program/movie, and identifies a user viewed location within the identified program/movie that corresponds to what was sensed by the terminal. The identification server identifies an Internet address of a media server from which the terminal can receive transmission of the identified program/movie. The identification server transmits a message to the terminal that identifies the identified program/movie, the user viewed location therein, and the Internet address of the media server. The terminal responds to the message by establishing a communication connection to the identified media server and requesting transmission therefrom of the identified program/movie starting from a location corresponding to the user viewed location.
