Patent number: 8787996Abstract: A mobile handset configured to estimate the radiation absorbed per mass of tissue of a user, and to perform an action in case the absorbed radiation exceeds a predefined threshold. The absorbed radiation may be estimated during a call. Additionally or alternatively, a prediction of the absorbed radiation level may be estimated and given to the user while the handset is not engaged in a call. various data items such as received power per time, estimated absorbed radiation and location may be transmitted to a server. A server application may use these data items to create regional maps of a cellular network coverage and quality by accumulating multiple inputs from a plurality of individual mobile handsets.Type: GrantFiled: March 12, 2013Date of Patent: July 22, 2014Assignee: Tawkon Ltd.Inventors: Gil Friedlander, Amit Lubovsky

Patent number: 8787997Abstract: Methods and systems for a distributed leaky wave antenna (LWA) are disclosed and may include communicating RF signals at one or more frequencies via distributed LWAs in a wireless communication device. The distributed LWAs may be integrated in one or more multi-layer support structures. The RF signals may be communicated at the one or more frequencies via a plurality of cavity heights in the distributed LWAs or via a plurality of sections of the distributed LWAs with different partially reflective surfaces. The distributed LWAs may be configured to transmit the RF signals at a desired angle from a surface of the multi-layer support structures. The distributed LWAs may include microstrip or coplanar waveguides where the plurality of cavity heights of the one or more distributed LWAs may be configured based on distances between conductive lines in the waveguides.Type: GrantFiled: March 31, 2010Date of Patent: July 22, 2014Assignee: Broadcom CorporationInventors: Ahmadreza Rofougaran, Maryam Rofougaran
