20080246732 | METHOD AND APPARATUS FOR MASKING KEYSTROKE SOUNDS FROM COMPUTER KEYBOARDS - Disclosed herein is a method of masking audible sounds emanating from a keyboard in response to a stroking of keys on the keyboard, the method comprising, selecting components from a plurality of components with various masses, building the keyboard with the selected components, moving a movable mass within the keyboard, and energizing a driving transducer within the keyboard. Further disclosed herein is a keyboard for a computer, comprising a plurality of keys, a cover with the keys protruding therethrough, a base supporting the cover and the keys, and at least one selectable mass wherein the mass is selected from a plurality of masses, a movable mass supported by the base and movable relative to the base, and a driving transducer supported by the base. | 10-09-2008 |
20090201640 | NOISE-REDUCING ATTACHMENT APPARATUS FOR HEAT EXCHANGER DOOR OF AN ELECTRONICS RACK OF A DATA CENTER - A noise-reducing attachment apparatus for a heat exchanger door is provided for facilitating attenuation of noise emanating from an electronics rack. The apparatus includes a frame structure configured to coupled to the heat exchanger door. The door includes in air opening and air-to-liquid heat exchanger, and air passing through the air opening also passes across the heat exchanger. The air opening facilitates passage of external air through the electronics rack. The frame structure defines in part an airflow channel through the apparatus, wherein air passing through the air opening also passes through the airflow channel when the apparatus is operatively coupled to the door. An acoustically absorptive material, which is coupled to the frame structure and at least partially defines the airflow opening through the apparatus, is selected and positioned to attenuate noise emanating from the electronics rack when the apparatus is coupled to the heat exchanger door. | 08-13-2009 |
