Abstract: For determining a position of a tool at least one sound generated by an operation performed by the tool is detected. Further, the position of the tool is then determined based on a timing of the detected at least one sound generated by the operation performed by the tool.

Abstract: A device, system and method for determining a position of a movable object on a two-dimensional surface obtains, via an image capture device attached to the movable object, at least one image of a portion of the two-dimensional surface. At one virtual marker is identified in at least one image, and a previously determined estimated position of the at least one virtual marker is retrieved. The previously determined estimated position determined from a combination of an image of at least one anchor point on the two-dimensional surface, the at least one anchor point defining a unique position on the two-dimensional surface, and odometry measurements based on at least two images of the two-dimensional surface. The position of the movable object on the two-dimensional surface is determined from the estimated position of the at least one virtual marker.

Abstract: A distance measuring system is provided that includes a first device having a transmitter configured to simultaneously transmit an electromagnetic signal and a sound signal. The distance measuring system also includes a second device located at a distance from the first device. The second device is configured to receive the electromagnetic signal at a first time and receive the sound signal at a second time, and calculate the distance of the second device from the first device based on a difference between the first time and the second time.

Abstract: A second device for measuring a distance from a first device is provided. The second device includes an electromagnetic receiver configured to receive an electromagnetic signal transmitted by the first device at a first time and a sound receiver configured to receive a sound signal transmitted by the first device at a second time. The electromagnetic signal and the sound signal are transmitted substantially at the same time. The second device also includes a processor configured to approximate the distance of the second device from the first device based on the first time, set a capturing window for capturing the sound signal based on the approximated distance and capture the sound signal within the set capturing window. The processor is configured to determine the distance of the second device from the first device based on the first time and the captured sound signal.
