Abstract: Technology for impedance matching with a re-configurable coil arrangement of multiple transmitter coils of an electronic device is described. One electronic device includes a wireless transmitter coupled to a power supply and an impedance matching circuit coupled to output terminals of the wireless transmitter. First switching circuitry of the impedance matching circuit, in response to a first control signal, is to switch either a first transmitter coil or a first conductive path in series between the output terminals. Second switching circuitry of the impedance matching circuit, in response to a second control signal, is to switch either a second transmitter coil or a second conductive path in series between the output terminals. The first transmitter and first conductive path have the same impedance and the second transmitter and the second conductive path have the same impedance.

Abstract: A wireless device having a first tunable antenna tuned to a first frequency band; and a second tunable antenna tuned to a second frequency band that is different than the first frequency band, wherein the first and second antennas are configured to transmit, receive, or a combination of transmit and receive transmission signals by carrier aggregation at the respective first and second frequency bands simultaneously.

Abstract: An antenna system includes an antenna having a symmetric geometry with respect to first and second antenna feed ports associated therewith, and a hybrid antenna feed circuit coupled to the first and second antenna feed ports of the antenna. The hybrid antenna feed circuit is configured to receive first and second transmit signals and feed the first transmit signal to the first and second antenna feed ports in a balanced feed mode and feed the second transmit signal to the first and second antenna feed ports in an unbalanced mode in a concurrent fashion.

Abstract: A gas detection device includes an enclosure having an interior chamber, an audio loudspeaker in acoustic communication with the interior chamber of the enclosure, and a gas sensor configured to detect a gas within the interior chamber of the enclosure. The device may include a ventilation port configured to permit two-way gaseous communication between the interior chamber and an atmosphere external to the enclosure, where the atmosphere comprises the gas. The audio loudspeaker is configured to generate a pressure within the interior chamber. The pressure causes a portion of the external atmosphere to be drawn into the interior chamber via the ventilation port. The gas sensor may include an emitter and a receiver. The gas detection device can be integrated into a mobile electronic device, such as a smartphone or tablet computer.

Abstract: Described herein are architectures, platforms and methods for implementing an orientation-agnostic mm-wave antenna(s) that includes an integrated second mechanism on a waveguide structure of the mm-wave antenna. The second mechanism, for example, operates on a second signal and is co-running with an operation of the waveguide structure. The second mechanism may include an audio sub-system such as an audio speaker and/or an audio microphone, or other mechanisms such as a sound or a signal detector, signal transmitter/receiver, or the like.

Abstract: An apparatus for antenna arrangement isolation is described. The apparatus includes a first antenna element (for example, a CMMB TV antenna) having a first radiator component and a second antenna element (for example, a cellular antenna) having a second radiator component. A first portion of the first radiator component is adjacent to a second portion of the second radiator component.
