Abstract
A security system and method including a transmitter broadcasting an inaudible signal. The security system further includes one or more sensors configured to detect the inaudible signal. The security system further includes a processing system in communication with the one or more sensors. The processing system tracks the inaudible signal of the transmitter throughout a location in response to detecting the inaudible signal.
Claims20
A security system, comprising:
- a transmitter broadcasting an inaudible tone, wherein the inaudible tone is an audio tone that is inaudible to humans, wherein the transmitter is integrated in a tag configured for attachment to a user or object;
- one or more sensors configured to detect the inaudible tone from the transmitter throughout a location;
- a processing system in communication with the one or more sensors, wherein the processing system tracks the transmitter throughout a location in response to detecting the inaudible tone utilizing the one or more sensors.
A method for utilizing inaudible tones, comprising:
- receiving an inaudible tone broadcast from a transmitter integrated in a tag, wherein the inaudible tone is an audio signal that is inaudible to humans;
- determining information associated with the inaudible tone;
- associating the tag with a location where the inaudible tone was received;
- and
- saving the information for subsequent access.
2 more elements
A system for processing inaudible tones, comprising:
- a processor for executing a set of instructions;
- and
- a memory for executing the set of instructions, wherein the set of instructions are executed to:
- receive an inaudible tone broadcast from a transmitter, determine information associated with the inaudible tone, associate the transmitter with a location where the inaudible tone was received, track the location of the transmitter throughout the location utilizing the inaudible tone, and save the information and tracked locations for subsequent access, wherein the inaudible tone is an audio signal that is inaudible to humans.
