    Abstract: 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.

  • Patent number: 9203157
    Abstract: In antenna device, a coil conductor of an antenna coil module and a conductor layer at least partially overlap. A current flows in the conductor layer to block a magnetic field generated by a current flowing in the coil conductor. A current flows along the periphery of a slit and around the periphery of the conductor layer due to a cut-edge effect. Since magnetic flux does not pass through the conductor layer, magnetic flux attempts to bypass the conductor layer along a path in which the conductor opening of the conductor layer is on the inside and the outer edge of the conductor layer is on the outside. As a result, the magnetic flux generates large loops that link the inside and the outside of a coil conductor of an antenna on a reader/writer side to couple an antenna device and the antenna on the reader/writer side.

During transmission of radio-frequency signals, antennas and wireless communications circuitry of the wireless electronic device may produce associated time-varying magnetic fields. One or more components may be covered with magnetic-resistant shield structures that protect the components from the time-varying magnetic fields by preventing magnetic-induced vibrations. The magnetic-resistant shield structures may include a conductive base layer such a layer of brass. A magnetic-resistant layer may be plated onto the conductive base layer. The magnetic-resistant layer may be formed from an amorphous nickel-phosphorous alloy. The amorphous nickel-phosphorous alloy may be produced by controlling the manufacturing temperature and proportion of phosphorous in the alloy while performing the plating operations within a length of time that ensures non-equilibrium conditions during the plating operations.

  • Patent number: 8970376
    Abstract: Methods, systems, and articles of manufacture for assigning priority to antennae are disclosed. In accordance with a preferred embodiment of the invention, reader antennae identify the location of an object by detecting a tag or other identifier associated with each object. Sensors can be provided to provide additional information regarding the environment of the objects or their surroundings. A priority order is assigned to the reader antennae based on the location and other characteristics of the objects and/or their environment. A polling sequence for reading the reader antennae is determined according to the priority order.

  • Publication number: 20150057053
    Abstract: A wireless terminal with a reduced Specific Absorption Rate (SAR) peak value and a method for reducing an SAR peak value by using the wireless terminal are disclosed. The wireless terminal with a reduced SAR peak value includes a first antenna configured to receive or transmit a communication signal, and further includes: a second antenna configured to feed a coupling signal when the first antenna receives or transmits the communication signal, and a signal processing module configured to process the coupling signal to reduce an SAR peak value of the communication signal for a human body. The energy of a superposed signal in a human body orientation is reduced by superposing the coupling signal with the communication signal, so as to reduce the SAR peak value effectively.

  • Publication number: 20150042535
    Abstract: An antenna for receiving and/or transmitting electromagnetic radiation, e.g. circularly polarized waves. The antenna is built of three parts. A radiating element in the form of a sequentially rotated array of 4 dual inverted-L shaped surfaces, where each individual radiating element is fed with the same magnitude and a 90° sequential phase difference for the purpose of creating right or left hand circular polarization. A ground plane. And optionally, a structure that resembles a dual so-called choke ring structure on which the array is mounted. This structure improves the axial ratio and radiating pattern of the radiating elements and also serves as housing/shielding of the accompanying electronics like low noise amplifiers and power conditioning.
