Wayfinding system
First Claim
1. A wayfinding device for providing directions to a desired destination within a building having a plurality of wayfinding beacons configured to transmit data using an ultrasound signal, the ultrasound signal comprising a plurality of bursts, wherein a sequence of predefined time intervals between consecutive bursts within the plurality of bursts uniquely identifies each wayfinding beacon, comprising:
- a programmable device separate from the wayfinding beacons, the programmable device comprising a wayfinding beacon recognition component configured to identify a wayfinding beacon when the programmable device receives the data through the ultrasound signal from a wayfinding beacon;
the programmable device being programmed to provide directions to a user of the programmable device in a direction toward the desired destination in response to identifying a wayfinding beacon.

Abstract
A wayfinding device is provided for giving directions to a desired destination within a building having a plurality of wayfinding beacons configured to transmit data using an ultrasound signal. The ultrasound signal can include a plurality of bursts, wherein a sequence of predefined time intervals between consecutive bursts within the plurality of bursts uniquely identifies each wayfinding beacon. The wayfinding device is separate from the wayfinding beacons and includes a wayfinding beacon recognition component configured to identify a wayfinding beacon when the device receives the data through the ultrasound signal from a wayfinding beacon. The device is further programmed to provide directions to a user of the device in a direction toward the desired destination in response to identifying a wayfinding beacon.

20. A non-transitory computer-readable storage medium with an executable program stored thereon, wherein the program instructs a processor to perform the following steps:
-
receive a desired destination to which a user wishes to go; obtain an ultrasound signal in the form of a series of bursts; decode the ultrasound signal to determine current location information; determine a direction for a user to proceed in so as to advance from the current location to the desired destination; and convey the direction to the user. - View Dependent Claims (21, 22, 23)
