    摘要： A computer system housing with a curved bezel that forms one or more sideways gap between a side of the computer housing chassis and the bezel attached to that side. Typically, the curved bezel is attached to the front of the chassis with each sideways gap extending perpendicularly from the front of the chassis to a predetermined width and stretching to predetermined length along the front of the chassis. The sideways gaps facilitate increased air inlet from the sides and allow efficient cooling of various system components that are mounted on the chassis and housed within the housing. One or more cooling fans may be mounted at different locations within the housing to optimize air circulation and, hence, cooling within the housing. The chassis may be partitioned into two separate sub-chassis for proper positioning of the cooling fans as well as to accommodate changes in computer system configurations with minimized retooling of the chassis.

    摘要： A computer system housing where a vertical printed circuit board, e.g., a riser card, is inserted into a socket on a computer system motherboard. Some internal space within the housing may allow optimization of system memory capacity through packing of additional memory modules on the riser card. The additional memory may be mounted on the riser card and may reside in the vertical space created between the riser card and the directly-mounted memory on the motherboard. The computer system housing further includes a chassis that may be partitioned into two separate sub-chassis for proper positioning of one or more cooling fans as well as to accommodate changes in computer system configurations with minimized retooling of the chassis. The cooling fans may be mounted at such locations on the chassis that allow optimization of air circulation and, hence, cooling within the housing. However, extra cooling fan(s) for the additional memory on the riser card may not be necessary in view of the creation of dedicated cooling channels within the housing by an efficient placement of the cooling fans. The optimization of fan placement within the housing results in efficient cooling of various system components and allows for increase in system component packing density without a similar increase in the number of cooling fans.

    摘要： A method and apparatus to vertically mount a first printed circuit board into a high-density connector on a second circuit board using one or more torque-limiting screws. A suitable support structure or support surface may be mounted on the second circuit board with the top of the support structure lying below the high-density connector in such a manner as to align the connecting edge on the first circuit board with the longitudinal opening in the high-density connector when the first circuit board is placed on the top surface of the support structure. One or more torque-limiting screws may be mounted on appropriated edges of the first circuit board. One or more grooved channels, preferably equal in number to the torque-limiting screws on the first circuit board, may be provided on the top of the support structure. The torque-limiting screws on the first circuit board are oriented in line with the corresponding grooved channels when the first circuit board is placed on the top of the support structure. The connecting edge on the first circuit board gets inserted into the high-density connector on the second circuit board when the torque-limiting screws are fastened into the grooved channels. The use of one or more torque-limiting screws and a suitable stable support structure may generate a high insertion force over a short insertion distance without overtightening the screws and may also prevent damage to the delicate high-density connecting edge of the first circuit board due to over-insertion. A simple mechanism to insert and remove one circuit board from the other may thus be achieved.

    摘要： A database system providing SQL extensions for automated encryption and decryption of column data is described. In one embodiment, for example, in a database system, a method is described for providing automated encryption support for column data, the method comprises steps of: defining Structured Query Language (SQL) extensions for creating and managing column encryption keys, and for creating and managing database tables with encrypted column data; receiving an SQL statement specifying creation of a particular column encryption key; receiving an SQL statement specifying creation of a database table having particular column data encrypted with the particular column encryption key; and in response to a subsequent database operation that requires the particular column data that has been encrypted, automatically decrypting the particular column data for use by the database operation.
