    Abstract: An ultrasound power transmitter comprising a transmit ultrasonic transducer array has a plurality of transmit ultrasonic transducers. The ultrasound power transmitter activates a set of transmit ultrasonic transducers in close proximity of an electronic device to be arranged to beam ultrasound energy to the electronic device. Alignment magnets of the ultrasound power transmitter are aligned with corresponding alignment magnets of the electronic device to manage the ultrasound beaming. The ultrasound energy may be converted into electric power to charge the battery of the electronic device. Feedbacks may be provided by the electronic device to the ultrasound power transmitter to increase power transmission efficiency. The ultrasound power transmitter may pair the electronic device with other different electronic devices utilizing ultrasonic signals. A spacer with good ultrasound power transmission properties may be located between the ultrasound power transmitter and an ultrasound power receiver of an intended electronic device to enhance power transmission.

    Abstract: Embodiments described herein relate to generating an image of an acoustic field associated with an underwater region. A plurality of submersible sensing devices (SSDs) are disposed so as to be substantially separate from each other in an underwater region, wherein each respective SSD is configured to execute a sink/float mission. During at least a portion of the sink/float mission, within each SSD, an environmental sensor measures at least one environmental parameter, a position sensor detects position information, an acoustic detection sensor detects at least one underwater signal, and a data recording system records mission data. After the sink/float mission, a processor receives mission data from the SSDs and generates an acoustic field image. Advantageously, during the sink/float mission some SSDs can transmit an orthogonal high time-bandwidth signal to help prevent interference between SSD during acoustic detection.

    Abstract: This document describes systems, methods, devices, and other techniques for sharing navigation data among computing devices. The techniques can include identifying, by a first computing device, a second computing device, based on the first computing device detecting an audio signal emitted by one or more speakers of the second computing device, wherein the second computing device is running a navigation application that has been programed to navigate a geographic route. Using information encoded in the audio signal that was emitted by the one or more speakers of the second computing device, the first computing device can determine the geographic route that the navigation application running on the second computing device has been programmed to navigate. A representation of the geographic route can be displayed on an electronic display of the first computing device.

    Abstract: Provided is an ultrasonic-wave communication system where the influence of ambient noise and the Doppler effect are suppressed and where a user of a portable terminal is prevented from hearing unwanted sound. After performing encryption processing of predetermined information such as store information, a beacon 5 sends out predetermined-information-containing beacon information of one channel as ultrasonic waves into the salesroom 3 by combining a control carrier, a first carrier, and a second carrier in such a way that a first carrier signal and a second carrier signal are output between control carrier signals a number of times according to the predetermined information and that a state where the first carrier signal and/or the second carrier signal is output is maintained.

    Abstract: Embodiments disclosed herein provide systems and methods for acoustically transferring information between systems. In a particular embodiment, a method provides identifying information for acoustic transfer and determining an amount of time corresponding to the information. The method further provides acoustically transmitting a signal at a first time and, upon the amount of time elapsing since the first time, acoustically transmitting the signal at a second time.

    Abstract: Ultrasonic transducers that are capable of generating increased levels of ultrasound, as well as receiving ultrasonic waves with increased sensitivity. The ultrasonic transducers include a back cover, a protective front cover, a backplate, and a vibrator film layer disposed between the backplate and the protective front cover. The backplate includes a plurality of grooves formed on a surface thereof facing the vibrator film layer. Each groove includes upper edges having cross-sectional contours that gradually tend toward the deepest part of the groove to allow a larger area of the backplate to be closer to the vibrator film layer, thereby increasing the resulting electric field, and, consequently, increasing the output power and sensitivity of the ultrasonic transducer.
