摘要： A re-configurable RF architecture includes both a 2×2 MIMO mode and a 1×2 MIMO mode The 2×2 MIMO mode includes a first RF chain coupled with a first dual band antenna and configured to both transmit (Tx) and receive (Rx) using two different RF protocols. The 2×2 MIMO mode also includes a second RF chain coupled with a second dual band antenna and configured to both Tx and Rx using a single RF protocol. The first RF chain may be coupled with a third antenna configured for near field proximity sensing. The RF architecture is reversibly switchable from the 2×2 MIMO mode to the 1×2 MIMO mode when near field proximity detection is required. In the 1×2 MIMO mode the Tx/Rx capabilities of the second chain using the second dual band antenna are retained and the first chain is configured for Rx only capability using the third antenna.

More specifically, disclosed are systems, components and methods to autonomously discover and/control operation of devices, such as media devices, by modulating and demodulating packet characteristics to establish an overlay communication channel. In various embodiments, a method includes receiving at least one RF channel including an overlay communication channel over which packets convey message data modulated with characteristics of the packets. The method includes selecting the RF channel and demodulating a subset of the packet characteristic values to form extracted symbols. At least one method can select a device that autonomously discovers another device using modulated packet characteristics.

摘要： A reduced, lateral mode laser diode is fabricated using a self-aligning process which produces a well controlled weakly index-guided waveguide with strong current confinement. The structure includes ion implants for controlling current injection into the active region from the top of the ridge. The number of modes may be reduced to unity, resulting in a single lateral mode laser. A laser diode array is fabricated in the same way.

摘要： Protection from current and voltage spikes is provided for a laser array by attaching a reverse diode laser array to shared contact pads before the first laser array is bonded to those pads. The arrangement provides for surge protection even during fabrication of the laser package where device failure results from power surges before surge protection circuitry is in place. Surge protection is afforded by having a reverse diode of the reverse diode array electrically in parallel with a corresponding laser diode of the protected array when activated.

摘要： Embodiments of the present application relate generally to electronic hardware, computer software, wireless communications, network communications, wearable, hand held, and portable computing devices for facilitating communication of information and presentation of media. An electrically conductive substrate, such as a sheet of metal or metal alloy, for example, includes an active antenna formed by a slot or opening formed in the substrate, and also includes at least one separate passive slot or opening (e.g., a passive slit) formed in the substrate. The active antenna may be intentionally detuned from one or more target frequencies (e.g., 802.11, 2.4 GHz, 5 GHz) such that the active antenna is not optimized (e.g., is not tuned) for the one or more target frequencies. One portion of the active antenna may be electrically coupled with a ground potential. Another portion of the active antenna may be electrically coupled with a RF receiver, transmitter, or transceiver.
