Rack enclosure

An enclosure is provided for housing electronic equipment that accommodates the different cooling and ventilating requirements of different types of equipment. The enclosure is constructed and arranged to support cooling airflow in a front-to-back configuration through the enclosure and in a side-to-side configuration from one side to an opposite side of the enclosure. The enclosure can thereby provide within a single enclosure means cooling air for components using front-to-back airflow for cooling, such as information technology (IT) equipment, and for components using side-to-side airflow, such as certain types of telecommunications equipment. The enclosure can thereby support a mix of IT and telecommunications equipment, providing flexibility and adaptability in network room and data center configuration. The enclosure is further configured to separate intake air used by equipment for cooling from exhaust air vented by equipment into its interior during operation. As a result, the enclosure promotes sufficient equipment cooling and prevents / minimizes equipment overheating.

Cable and air management adapter system for enclosures housing electronic equipment

The present invention provides a cable-air management adapter system ("CAMAS") that addresses airflow, heat buildup and cable routing concerns in enclosures that house electronic equipment. The CAMAS allows users to work from a single frame to increase an enclosure's size by adding multiple expansion channels that form a platform on which multiple airflow, heat dissipation and cable support management options are installed, eliminating the need to replace the enclosure.

Hermetically sealed electronics arrangement and approach

A hermetic sealing approach involves welding an Aluminum cover onto a low-cost Aluminum housing. According to an example embodiment of the present invention, a metal housing having a base and sidewalls extending upward therefrom is adapted to receive and couple to an HDD arrangement. The metal housing is formed using material and processing (e.g., cold formed or die cast Aluminum) that are relatively inexpensive. A feedthrough arrangement including a plurality of communication pins extends through an opening in the base and is coupled thereto, with the communication pins adapted to pass signals between the inside and the outside of the metal housing. A metal cover is welded to an upper portion of the sidewalls and, with the feedthrough arrangement, hermetically seals the metal housing.

Magnetic data storage fixed hard disk drive using stationary microhead array chips in place of flying-heads and rotary voice-coil actuators

A magnetic data storage fixed hard disk drive using stationary Microhead Array Chips in place of conventional Flying-Heads and Rotary Voice-Coil Actuators or other Servo-Tracking mechanisms. Every Microhead Array Chip has a minimum of one thousand or maximum of four billion individual and addressable microhead read and write data-transducers built into it. The hard disk drive unit assembly that uses the Microhead Array Chip approach will have within its assembly as few as two or as many as twenty-eight installed Microhead Array Chips. The Microhead Array Chip hard disk drive unit assemblies will have at least one storage disk-platter with two disk-platter data-surfaces containing a multiplicity of concentric data-tracks that rotates at a substantially constant angular velocity. While Microhead Array Chips are made stationary by specially designed circuit boards, that positions a Microhead Array Chip over each of two data-surfaces of every disk-platter within the hard disk drive assembly. The total number of microheads within a stationary positioned Microhead Array Chip's Microhead Array is what determines the total number of available tracks on and across a data-platter's data-surface (i.e., 65,000 microheads would equal 65,000 cylinder / tracks).

Hard disk drive housing apparatus and electronic apparatus

In a hard disk drive (HDD) or an electronic apparatus in which the HDD is wrapped with a foam resin sheet with a noise absorption effect and a metal outer casing to thereby damp noise, a sub-assembly wrapping body incorporating therein the HDD wrapped with a wrapping body composed of a slippery film sheet with foam resin sheets attached thereto is mounted into the metal outer casing through the slippery surface of the slippery film sheet. In order to insulate a noise generated from a recording and reproducing drive apparatus such as the HDD, the system for use with the HDD and the electronic apparatus can simplify the assembly process required when the HDD is loaded into the outer casing serving as a noise insulation box through a noise absorption member.

Packaging microelectromechanical structures

A MEMS device may be formed in a hermetic cavity by sealing a pair of semiconductor structures to one another, enclosing the MEMS device. The two structures may be coupled using surface mount techniques as one example, so that the temperatures utilized may be compatible with many MEMS applications. Electrical interconnection layers in one or the other of these structures may be utilized to allow electrical interconnections from the exterior world to the MEMS components within the cavity.

Field serviceable electronic display

An electronic display which can be serviced without having to remove the display from its mounted position. A front housing and a rear housing are hingedly attached so that the front housing can rotate and allow access to the interior of the display. An axial force mechanism can be used to aid in rotating the front housing to an open position. A locking collar, support member, or axial locking member may be used to ensure that the front housing remains open. A removable front glass assembly or removable glass panel may be used with an exemplary embodiment. The front glass assembly or glass panel can be easily replaced if it becomes damaged by minimally-trained personnel. Gutters may be used between the front and rear housing as well as the front housing and front glass assembly to ensure an adequate seal against contaminates.
