    Abstract: A position detection system comprising positional element and positioning device, wherein the positional element transmits a continuously modulated acoustic waveform and a synchronization signal that is a sequence of at least two synchronization packets, each bearing timing data for the continuously modulated acoustic waveform. Additionally, the synchronization signal uses time hopping to support concurrent positioning of a plurality of positional elements.

    Abstract: An acoustic positioning system comprises a receiver which has at least two microphones and which generates a signal in response to ultrasound waves that it receives. At least one microphone is mounted on the receiver so that an outer surface 5 of the microphone is substantially flush with a surface of the receiver adjacent to and surrounding the microphone. The term 'substantially flush' means within half a wavelength of the lowest frequency used. The system also includes an implement which is movable relative to the receiver on a positioning surface on top of which the receiver rests in use, and which comprises at least one ultrasound transmitter that 10 transmits ultrasound waves to the receiver. The system further includes a controller that uses the signal to track a position of the implement on the positioning surface.

    Abstract: A robotic system including at least two acoustic sensors, spaced apart, for receiving respective versions of a respective continuous ultrasonic waveform emitted by each of one or more positional elements, each of the respective continuous ultrasonic waveforms comprising a respective modulated carrier and an electromagnetic sensor for receiving a respective electromagnetic signal emitted by a respective electromagnetic emitter of a same respective one of the positional elements, and a computing device. The respective electromagnetic signal is emitted in coordination with the respective ultrasonic waveform emitted by the same positional element. The computing device decodes the versions of the ultrasonic waveform and the electromagnetic signal to measure time delays between the versions of the respective ultrasonic waveform and the respective electromagnetic signal, converts the time delays to distances, and triangulates the distances to determine positions of the positional elements. A robot maneuvers based on the determined positions.

    Abstract: An acoustic positioning system is disclosed. The acoustic positioning system comprises: (a) a receiver comprising at least two microphones; (b) an implement that moves relative to the receiver; and (c) a controller. The receiver comprises at least two microphones that generate a signal in response to ultrasound waves that it receives. At least one microphone is mounted on the receiver so that an outer surface of the microphone at a front side of the microphone is substantially flush with a surface of the receiver adjacent to and surrounding the microphone. A maximum discontinuity between the outer surface of the microphone and the adjacent surface is no more than half a wavelength of the lowest frequency used. The implement that moves relative to the receiver moves on a positioning surface on top of which the receiver rests, and comprises at least one ultrasound transmitter that transmits ultrasound waves to the receiver. The controller uses the signal to track a position of the implement on the positioning surface.
