Patent number: 9337530Abstract: Methods and apparatuses for capturing at least a portion of the radio frequency (“RF”) radiation emitted from an electronic device or other external sources and converting it into electric current that can be used for a number of different functional purposes including to drive a circuit that provides an indication when the RF radiation is captured and its relative intensity. One of the advantages of these techniques is that users can be protected from the potential harmful effects of long-term exposure to the RF radiation emitted from electronic devices, particularly for wireless phones which are often held in close proximity to a user's body. The indication can provide users with an indication that the circuit is redirecting the RF radiation away from their bodies and dissipating it as electrical energy.Type: GrantFiled: May 24, 2012Date of Patent: May 10, 2016Assignee: Protek Innovations LLCInventors: Shaun M.

Patent number: 9316723Abstract: An integrated differential high power amplifier-radiator array that overcomes the prior art impedance match issues is described. An impedance matching balun is used to feed a high output impedance, differential HPA, which in turn drives a wide band radiator or array of radiators having a matching input impedance to provide a highly efficient, compact transmit system. In one exemplary embodiment, the HPA may be a high impedance Class-B HPA configured as a push-pull cascode amplifier. A high impedance isolator or circulator may be used between the HPA and the radiator. One of ordinary skill in the art will readily appreciate that a receive implementation, using a properly matched low noise amplifier in place of the HPA, is also possible. Similarly, with the addition of a slotline circulator, transceiver operation is also attainable with the addition of an impedance matched receive chain.Type: GrantFiled: May 24, 2012Date of Patent: April 19, 2016Assignee: RAYTHEON COMPANYInventors: Reza Tayrani, Walter B.
