Abstract: A method for estimating a range of a moving target, the method including emitting, from a target, a first ultrasound signal T, wherein the first ultrasound signal T is generated based on a first differential Zadoff-Chu sequence x; receiving, at a receiver, a second ultrasound signal R, which corresponds to the first ultrasound signal T, wherein the second ultrasound signal R includes a second differential Zadoff-Chu sequence y; correlating the first ultrasound signal T with the second ultrasound signal R to calculate an initial time of flight estimate taucorr; and calculating an initial range estimate dcorr by multiplying the initial time of flight estimate taucorr with a speed of sound c. A differential Zadoff-Chu sequence is different from a Zadoff-Chu sequence.

Abstract: Described herein are methods and devices for improved location of any and all underwater structures or equipment installed underwater. In particular, systems are disclosed that combine optical and acoustic metrology for locating objects in underwater environments. The systems allow for relative positions of objects to be determined with great accuracy using optical techniques, and support enhanced location of devices that utilize acoustic location techniques. In addition, location information can be provided by the system even in conditions that make optical metrology techniques impossible or impractical.

Abstract: A system for tracking an instrument with ultrasound includes a probe (122) for transmitting and receiving ultrasonic energy and a transducer (130) associated with the probe and configured to move with the probe during use. A medical instrument (102) includes a sensor (120) configured to respond to the ultrasonic energy received from the probe. A control module (124) is stored in memory and configured to interpret the ultrasonic energy received from the probe and the sensor to determine a three dimensional location of the medical instrument and to inject a signal to the probe from the transducer to highlight a position of the sensor in an image.

Abstract: The systems and methods may transmit a plurality of locationing pulse requests from a mobile device in a vehicle to an audio system of the vehicle during a period of operation of the vehicle. The audio system may have an array of speakers disposed inside the vehicle, and the locationing pulse requests may include a request to emit a locationing pulse from the array of speakers. The systems and methods may further receive the locationing pulse at a microphone of the mobile device; and determine, based upon receiving the locationing pulse, that the vehicle was in service of a TNC company, or otherwise operating as a TNC vehicle, during the period of operation based upon passengers entering and leaving the vehicle during the period of operation. Insurance covering the operation of the vehicle for TNC use may be verified, and/or alternatively, offered to facilitate insuring TNC vehicle operation.

Abstract: A system may include a fixed communications device and a mobile communications device each configured to wirelessly communicate at a first frequency and also at a second frequency higher than the first frequency. The fixed communications device and the mobile communications device may cooperate to establish a wireless link via the second frequency, exchange a location signal via the first frequency responsive to establishing the wireless link, communicate via the wireless link using the second frequency and determine respective transmit and receive delays associated with transmission and reception of the location signal via the first frequency, and determine a distance between the fixed communications device and the mobile communications device based upon a time of arrival of the location signal, the transmit and receive delays, and a signal speed associated with the second frequency.

Abstract: A leaky-wave antenna for fluid environments includes a waveguide cavity defined by a waveguide wall. The waveguide cavity is filled with a waveguide fluid. The waveguide walls are made of either an anisotropic material that utilize one of orthotropic stiffness of the anisotropic material to control mode conversion, a band gap material to approximate an acoustically rigid boundary, and a combination of the two materials.
