Heh! Finally a profitable pivot idea for uBeam! Get their ultrasound transmitters mounted in hats or sunglasses, instant &quot;privacy shield&quot;! ;-)<p>(Bug report #0000001: &quot;I charged my iPhone up by carefully holding it within 8 inches of my uBean transducer all night then when I went to make a call in the morning with my uBeam Privacy Sunglasses(tm) on, the other party couldn&#x27;t hear anything I said.&quot; Response: &quot;Closed WONTFIX. You&#x27;re holding it wrong.&quot;)
