20100108350 | Cable For High Speed Data Communications - Cables and methods of manufacturing cables for high speed data communications, the cable including: a first inner conductor enclosed by a first dielectric layer and a second inner conductor enclosed by a second dielectric layer, the inner conductors and the dielectric layers parallel with and along a longitudinal axis; and folded conductive shield material wrapped in a rotational direction along and about the longitudinal axis around the inner conductors and the dielectric layers, including overlapped wraps along and about the longitudinal axis, the conductive shield material comprising a first conductive layer and second conductive layer separated by an inner-shield dielectric layer. | 05-06-2010 |
20100252358 | Airflow Optimization and Noise Reduction in Computer Systems - In one embodiment, a fan is used to generate airflow through a computer chassis to a fan air inlet. An audible frequency component of the airflow is identified and selected. A sound wave is generated having a generated frequency equal to the selected audible frequency component of the airflow. The generated sound wave is introduced into the airflow with the generated frequency out of phase with the audible frequency component of the airflow. The magnitude of the generated frequency may be selected as a function of fan speed and/or air sensed pressure within the airflow. The frequency, phase, and magnitude of the generated sound wave may be selected and enforced by a baseboard management controller. | 10-07-2010 |
