Abstract: A portable computing device having a substantially non-conducting outer housing and alternative electrical grounding and audio system architectures is disclosed. The device can be a laptop computer having a main logic board, a keyboard assembly, an audio source positioned below the keyboard assembly, and an equalizer electrically coupled to the audio source, with each of these components being electrically coupled to a universal grounding structure. The audio source emits sound waves that are propagated through the keyboard assembly and between gaps between keyboard keys and the outer housing. Settings for the equalizer can be selected to account for sound absorption and amplification characteristics of the sound waves along these sound transmission paths.

Abstract: The present application describes various embodiments of systems and methods for providing internal components for portable computing devices having a thin profile. More particularly, the present application describes internal components configured to fit within a relatively thin outer enclosure.

Abstract: Methods and apparatus for mitigating the effects of interference between multiple air interfaces located on an electronic device. In one embodiment, the air interfaces include a WLAN interface and PAN (e.g., Bluetooth) interface, and information such as Receiver Signal Strength Index (RSSI) as well as system noise level information are used in order to intelligently execute interference mitigation methodologies, including the selective application of modified frequency selection, variation of transmitter power, and/or change of operating mode (e.g., from multiple-in multiple-out (MIMO) to single-in, single-out (SISO)) so as to reduce isolation requirements between the interfaces. These methods and apparatus are particularly well suited to use cases where the WLAN interface is operating with high data transmission rates. Business methods associated with the foregoing technology are also described.

Abstract: Electronic devices such as portable computers may contain circuits that generate radio-frequency noise. The radio-frequency noise may interfere with the operation of sensitive circuitry such as wireless communications circuitry. The circuits that generate the radio-frequency noise may include differential signal drivers that drive signals onto communications lines such as lines in a bus or output interface. A control circuit may power the drivers at an adjustable driver voltage bias level. The amount of noise that is generated by the drivers may vary as a function of the voltage bias level and may produce different amounts of noise at different wireless frequencies. Computer lid position and other factors may also influence the amount of interference that is generated. The control circuit may determine the current operating state of the device and may make voltage bias level adjustments that minimize interference between the drivers and the wireless circuitry.

Abstract: Electrical communication between an information handling system chassis having a non-conductive surface and processing components within the chassis is established through the non-conductive surface with conductive elements extending from a conductive pad. A protruding element extending from a conductive pad engages the conductive elements through the non-conductive surface when the protruding element is coupled to a cavity formed in the chassis. Alternatively, the protruding element extends from the chassis to couple to a cavity in the conductive pad. Processing components have electrical communication with the chassis through the conductive pad.
