20090231788 | System and Method for Electrical Communication Through a Non-Conductive Information Handling System Chassis Surface - 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. | 09-17-2009 |
20110081858 | METHODS AND APPARATUS FOR ENHANCED COEXISTENCE ALGORITHMS IN WIRELESS SYSTEMS - 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. | 04-07-2011 |
20110091051 | PORTABLE COMPUTER ELECTRICAL GROUNDING AND AUDIO SYSTEM ARCHITECTURES - 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. The universal grounding structure includes a plurality of separate ground components that are electrically intercoupled, each being substantially smaller than the overall portable computing device, and also includes an electromagnetic interference shield around the main logic board. | 04-21-2011 |
20120074988 | ELECTRONIC DEVICE WITH DYNAMIC DRIVE STRENGTH ADJUSTMENT TO MITIGATE IMPACT OF SYSTEM NOISE ON WIRELESS PERFORMANCE - 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. | 03-29-2012 |

20090197746 | Exercise chair with side supporters - An exercise chair primarily directed to employing an exercise method, with foot bars, high bars, and a foldable configuration. The seat is supported by a plurality of support elements, at least some of which are hingeably connected with the seat, so that the chair can be folded into a compact shape for storage or transport. The independent foot bars may each be attached to a lever that is hingeably coupled with one or more of the support elements. The position of the foot bars may also be adjustable by extending out of the levers and locking into the desired position. One or more resistance elements may be removably attached to a location below the chair seat, and individually connected with the levers via an adjusting assembly that can either slide or be placed in pre-set mounting locations along the lever to provide variable resistance, or can be equipped with a turnbuckle to provide varying resistance. A platform that rests at or near the floor during use may be attached to the two front support elements, which provides stability as well as comfort when the user stands or kneels on the platform when using the chair. The high bars can be grasped by the user to perform a wide variety of exercises while standing on or moving from the seat, the foot bar, or the platform. | 08-06-2009 |
20130084180 | Fan With Power Deployed Fan Blade - A rotating fan with a transmission mechanism and a blade deployment mechanism. In an energized state, an electromagnetic coil generates a magnetic force that causes a clutch plate to be in contact with a contact surface, thereby engaging a planetary gear system. In a de-energized state, the clutch plate is not in contact with the contact surface, thereby disengaging the planetary gear system. In a deployed configuration, a drive link activated by the planetary gear system rotates a blade link to cause a fan blade to pivot. The result is that the fan blade tip is farther from the motor shaft than the fan blade root. In a retracted configuration, the drive link rotates the blade link to cause the fan blade to pivot and retract. The result is that the fan blade tip is equidistant from the motor shaft as the fan blade root. | 04-04-2013 |
