Abstract: A multiple-input, multiple-output (MIMO) transceiver comprises a plurality of RF chains, a plurality of antennas, a plurality of switching components, and control circuitry operatively coupled to the plurality of switching components. In some examples, a total quantity of RF chains included in the plurality of RF chains is equal to a first value, and a total quantity of antennas included in the plurality of antennas is equal to a second value that is less than the first value.

Abstract: A method for adjusting transmitter output power (PTX) comprises sensing, by a proximity sensor communicatively coupled to a transmitting device, whether an object is proximate to the transmitting device. The method further comprises analyzing an image from a camera to determine whether the transmitting device is proximate to a portion of a human body, when the proximity sensor senses the object proximate to the transmitting device. Further, the method comprises adjusting the PTX of an antenna operatively coupled to the transmitting device to be less than or equal to a SAR threshold output power (PSARMAX), when it is determined that the transmitting device is proximate to the portion of the human body or when it cannot be determined whether the transmitting device is proximate to a portion of a human body.

Abstract: A system includes a computing device operatively coupled to one or more user interface components, and a thermal cooling system for cooling the computing device. The system further includes a proximity sensor positioned adjacent a thermal vent and configured to set a proximity flag in response to detecting an object in proximity to the thermal vent. The system further includes an orientation sensor coupled to the computing device and configured to set an orientation flag in response to detecting an orientation of the computing device being such that the thermal vent is facing downward. The system further includes a processor communicatively coupled to the proximity sensor, the orientation sensor, and the one or more user interface components. The processor is configured to provide an alert for output through the one or more user interface components in response to having the proximity flag set or the orientation flag set.
