摘要： A programmable buoy system having one or more buoys capable of connecting through the internet to a buoy command server. The buoy command server relays commands to each of the one or more buoys in response to user commands sent from a buoys command interface application on a mobile device. The programmable buoy system includes one or more buoys each having a hull with two or more pontoons where the hull has a top side and bottom side. A stationary rudder extends downward from the bottom side of the hull to be positioned in a body of water when the one or more buoys are in use. A motor is pivotably connected on each one or more buoys, wherein the motor has a propeller positioned away from the bottom side of the hull. The propeller and motor move the select one of the one or more buoys in the body of water.

摘要： An indoor ultrasonic location tracking system that can utilize standard audio speakers to provide indoor ranging information to modern mobile devices like smartphones and tablets. The method uses a communication scheme based on linearly increasing frequency modulated chirps in the audio bandwidth just above the human hearing frequency range where mobile devices are still sensitive. The method uses gradual frequency and amplitude changes that minimize human perceivable (psychoacoustic) artifacts derived from the non-ideal impulse response of audio speakers. Chirps also benefit from Pulse Compression, which improves ranging resolution and resilience to both Doppler shifts and multi-path propagation that plague indoor environments. The method supports the decoding of multiple unique identifier packets simultaneously. A Time-Difference-of-Arrival pseudo-ranging technique allows for localization without explicit synchronization with the broadcasting infrastructure. An alternate received signal strength indicator based localization technique allows less accurate localization at the benefit of sparser transmission infrastructure.

摘要： A system, device and method that enables units to communicate with each other and point to each other's location without requiring line-of-sight to satellites or any other infrastructure. Further, the system, device and method are able to operate outdoors as well as indoors and overcome multipath interference in a deterministic algorithm, while providing bearings at three dimensions, not only location but actual direction.

摘要： A method comprises transmitting (901) a first ultrasonic ping signal from a first floating unit (M1). The first ultrasonic ping signal is received in an underwater device (D1, D2, D3). After a predetermined delay from the reception of the first ultrasonic ping signal, the underwater device transmits (905) a second ultra-sonic ping signal from the underwater device. The second ultrasonic ping signal is received in the first floating unit. The first floating unit determines a time difference between a time of transmission of the first ultrasonic ping signal from the first floating unit and a time of reception of the second ultrasonic ping signal, and based on the time difference, provides location information and/or other information to the underwater device by transmitting (910) to the underwater device sequential underwater ultrasonic ping signals such that time differences between the sequential underwater ultrasonic ping signals indicate the provided information.(FIG. 9)

摘要： A far end signal is received at a device, a marker signal is inserted into the far end signal and the far end signal with the marker signal is played on a speaker. A near end signal is received via a microphone and the marker signal is detected in said received near end signal. The detected marker signal is used to determine a delay that is then used to cancel at least some of an echo in the near end signal. The marker may be ultrasonic. The echo canceller and other processing may run at a lower sampling frequency than the marker detection.

摘要： The purpose of the present invention is to reduce the introduction cost of an indoor positioning system using inaudible sound. A positioning system according to one embodiment includes a first acquisition unit, a second acquisition unit, and a positioning unit. The first acquisition unit acquires a reception log indicating that a fixed receiver receives signal source-specific inaudible sounds from multiple signal sources. The second acquisition unit acquires, from a storage unit, signal source information on multiple signal sources corresponding to a fixed receiver installed near a mobile terminal. Here, the signal source information contains information for identifying a signal source from inaudible sound, the transmission timing of inaudible sound at the signal source, and the location of the signal source.
