摘要:
A cabinet for housing computer devices with an internal air distribution system is disclosed. The cabinet includes an internal chamber defined by a side wall arrangement having at least a front wall. The cabinet includes a support structure for computer devices, wherein the support structure is positioned within the internal chamber of the cabinet. The air distribution device comprises an elongated duct defining a passageway for air distribution. The duct is positioned within the internal chamber and has a plurality of adjustable air discharge ports that are in fluid communication with the passageway. The air distribution device further includes an inlet fan in fluid communication with the passageway. By precisely directing cool air to a frontal portion of the computer devices, the air distribution device reduces the temperature gradients within the cabinet and the quantity of heat that accumulates in the cabinet during operation of the computer devices.

Methods and apparatus for allocating computer hardware resources of a hard partition of a computer server system to one or more soft partitions. In response to a partitioning request, a nucleus firmware instance of a hard partition may be configured to launch a separate firmware instance corresponding to each requested soft partition, and to allocate partitionable hardware resources of the hard partition to the soft partitions by allocating the hardware resources to each separate firmware instance.

A method of removing a T-type fence post from the earth with a powered, mobile piece of equipment controlled by a human operator includes attaching a substantially flat plate to a lift arm of the powered, mobile piece of equipment such that the plate hangs substantially vertically from the lift arm and can move in an arc, the plate having an opening with a top wall and a bottom wall, moving the powered, mobile piece of equipment in a first direction to pull the plate over the fence post such that an upper portion of the post enters the opening with the bottom and upper walls of the opening engaging the post with sufficient force to retain the post in the opening when the post is pulled from the earth and raising the lift arm to pull the post from the earth in a substantially vertical direction.
摘要:
An inertial (“INS”)/GPS receiver uses injected alignment data to determine the alignment of the INS sub-system when the receiver is in motion during start-up. The alignment data is determined from parameterized surface information, measured GPS velocity, and a known or predetermined angular relationship between the vehicle on which the receiver is mounted and an inertial measurement reference, or body, frame associated with the accelerometers and gyroscopes of the inertial measuring unit (“IMU”). The parameterized surface information, which provides a constraint, may be the orientation of the surface over which the vehicle that houses the receiver is moving. The receiver uses the initial GPS position to determine the location of the vehicle on the parameterized surface, and thus, the known surface orientation. The receiver then determines the roll, pitch and heading of the vehicle on the surface using the associated GPS velocity vector. Thereafter, the receiver uses the calculated roll, pitch and heading of the vehicle and the known or predetermined angular relationship between the vehicle and the IMU body frame to determine a rotation matrix that relates the IMU body frame to a computation or referenced frame used by the receiver.

Methods and apparatus for subdividing a hard partition of a computer server system into one or more soft partitions using partition management programming installed within firmware of the server system. The partition management firmware may be disposed at least partially on a central service processor and may be programmed to present generic interfaces, so that operating systems do not require modification to interface with the partition management programming.

摘要:
A method for preparing stretchable bonded nonwoven fabrics which involves forming a substantially nonbonded nonwoven web of multiple-component continuous filaments or staple fibers which are capable of developing three-dimensional spiral crimp, activating the spiral crimp by heating substantially nonbonded web under free shrinkage conditions during which the nonwoven remains substantially nonbonded, followed by bonding the crimped nonwoven web using an array of discrete mechanical, chemical, or thermal bonds. Nonwoven fabrics prepared according to the method of the current invention have an improved combination of stretch-recovery properties, textile hand and drape compared to multiple-component nonwoven fabrics known in the art.

A system consisting of a base GPS receiver with a clear view of the sky, one or more remote GPS receivers with restricted views of the sky and a processing center that batch processes range information provided by the GPS receivers determines the positions of the remote GPS receivers to within tight tolerances. The base GPS receiver and the remote GPS receivers produce range information based on the satellite signals that the respective receivers can track at a given time, and provide the range information to the processing center. The range information includes both code and carrier measurements for each of the signals that are being tracked by the respective GPS receivers. The center collects the range information over an extended period of time, for example, hours, days or weeks, and then batch processes the collected information in multiple passes through the data, to calculate the precise latitude, longitude and height of the receiver. The center batch processes the data using a floating ambiguity filter that, after a first pass through the data, is initialized with the position calculated in an earlier pass. The center also calculates the quality of the collected range information by fixing the position and position covariance of the floating ambiguity filter and using double differences with the base GPS receiver measurements, to ensure that the information used in subsequent position calculations is sufficiently reliable.
