Abstract: An airflow guide includes a top cover and two side covers. The two side covers are disposed on opposite ends of the top cover. At least one of the two side covers includes a base plate and a sliding plate. The base plate is fixedly connected to the top cover. The sliding plate is slidably connected to the base plate. The sliding plate slides relative to the base plate, such that an air inlet is defined in the at least one of the two side covers.

Abstract: An approach is provided for messaging gateway services. It is determined whether a user profile specifies opting to receive content. The content is selectively forwarded, according to a multimedia protocol, to a device of a user as a multimedia messaging service (MMS) message or a short messaging service (SMS) message based on the determination, wherein the multimedia protocol supports both MMS messaging and SMS messaging.

Abstract: A speed adjustment circuit for a plurality of fans includes a voltage input terminal, a plurality of speed control modules, and a fan tachometer. Each of the speed control modules includes a fan connector, a speed adjusting unit, and a detector switch unit. The speed adjusting unit includes a switching control unit, a voltage adjusting chip, and a variable resistor. The detector switch unit includes a first switch. The voltage input terminal connects to the input terminal of the voltage adjusting chip through the switching control unit. The output terminal of the voltage adjusting chip connects to the power pin of the fan connector. The adjusting terminal of the voltage adjusting chip connects to ground through the variable resistor, and connects to the output terminal of the voltage adjusting chip through a resistor. The detection pin of the fan connector connects to the fan tachometer through the first switch.

Abstract: An exemplary server rack includes a box adapted for receiving a plurality of servers therein, a plurality of pivoting members pivotally connected to the box; and a plurality of covers fixed to the pivoting members respectively. The box includes a front board and a back board opposite to the front board. The front board and the back board both define a plurality of though holes adapted for airflow to pass therethrough. Each cover is operable to pivot relative to the box via the corresponding pivoting member, and thereby cover some of the through holes of the front board of the box.

Abstract: An air pressure drop detecting device for detecting air flow volume of a cooling fan includes a first pressure sensor, a second pressure sensor, and a display unit. The cooling fan has an air inlet and an air outlet opposite to the air inlet. The first pressure sensor is positioned in the air inlet and detects a plurality of first pressure values. The second pressure sensor is positioned in the air outlet and detects a plurality of second pressure values. The display unit is connected to the first pressure sensor and the second pressure sensor to display the first pressure values and the second pressure values, and a position of the cooling fan in the computer case is determined by the pressure difference between the first pressure values and the second pressure values.

Abstract: A server cabinet adapted for receiving servers therein includes a top plate, a bottom plate opposite to the top plate, a left side plate and a right side plate connecting with the top and bottom plates respectively, and a front side plate disposed between the top and bottom plates. The front side plate defines through holes therein. A total area of the through holes in an upper half portion of the front side plate is different from a total area of the through holes in a lower half portion of the front side plate. The front side plate is rotatable in a plane defined by the front side plate.

Abstract: A computer enclosure includes a chassis and a movable assembly. The chassis defines an opening. Two blocking pieces extend from the chassis at opposite sides of the opening. The movable assembly includes a post movably mounted to the chassis, and a closing member extending from a first end of the post and located between the blocking pieces to cover or uncover the opening with moving of the post.

Abstract: A method of web services throttling in a web application server environment, where a number of web services servers communicate with web services clients over a network. A request is received from a web services client which contains an account ID related to the web services client. An ID reader resident on one of the web services servers reads the account ID; and a value related to the account ID in a counter, resident on the one of the services servers, is incremented. The method also involves communicating with the remaining web services servers to increment the value in a plurality of counters, each of which is resident on one of the remaining web services servers. The web services servers compare the count value related to the account ID to a throttling limit value.

Abstract: An airflow guide includes a top cover and two side covers disposed on opposite ends of the top cover.
