Abstract: A location sharing component operating on a mobile computing device is configured to enable a local party and a remote party to share each other's locations during a phone call to facilitate a physical meet-up. The location sharing component exposes various options to set a length of time for the location sharing or the location can be shared up until the meet-up occurs. User interfaces (UIs) exposed by the location sharing component can provide directions and dynamically updated maps which show the locations of the parties. The location sharing experience can be persisted after the phone call ends by showing updates to the directions and maps and by surfacing notifications when the parties are close so that they can start looking for each other. The location sharing time interval can be extended if it is due to expire before the meet-up occurs.

Title: An acoustic device for forming a wall of sound underwater
Inventor: NEDWELL JEREMY ROSS
IPC: G10K11/26
Filed: 2017-07-24
Abstract: Walls of sound are useful in water for guiding fish away from areas. Hitherto, systems have used bubbles of water to facilitate the speed of travel of sound, but suffer from the ability to maintain a consistent wall of bubbles and are inefficient. An acoustic device is provided for forming a wall of sound underwater and comprises a transducer connected to an acoustic waveguide. The waveguide comprises one or more projections, whereby sound generated by the transducer travels along the projection(s) to form the wall of sound. The waveguide may comprise compressible projections formed from neoprene.  These projections are arranged in a fan or frond shape. In addition or alternatively, the projections may be laminar. The projections could be of different lengths. The location, arrangement and lengths of the projections are all suited to the underwater location to maximise the effectiveness of the wall of sound.
