Abstract: Embodiments include methods for determining synchronization/pilot sequences (SPS) to be utilized in conjunction with transmissions by antennas of a multiple-antenna transmitter. The SPS include pilot signals that are positioned at subcarriers that are orthogonal in frequency with subcarriers at which pilot signals of other antennas are positioned. The pilot signals may be unevenly spaced across the in-band subcarriers. The multiple-antenna transmit system generates a plurality of wireless signals, each of which may include an SPS having synchronization information in a first plurality of in-band subcarriers and the pilot signals in a second plurality of in-band subcarriers. The wireless signals are simultaneously radiated over a wireless communication channel using a different antenna. A receiver receives channel-affected versions of the wireless signals, and produces a corrected signal by applying corrections to the received signal based on estimated channel perturbations within the received signal.

Abstract: Aspects for detection and correction of entrance into an improper master boot record (MBR) state in a computer system are described. The aspects include providing a proxy MBR at a predetermined location on a storage device of a computer system to provide a proxy MBR. The proxy MBR is then utilized during a restart operation. An original MBR maintained at an original location on the storage device is then utilized during a reboot operation when the utilization of the proxy MBR is unsuccessful.

Abstract: A remote control application is loaded and executes on a service processor independent from a main processor within a remotely managed system, prior to power on for the main processor. The remote control application grabs and packetizes video data from the remotely managed system for transmission to the remote console via a TCP/IP connection transport layer, and receives keyboard/mouse signals in the same manner for insertion into the remotely managed systems's keyboard/mouse controller(s) as though originating from locally attached peripherals. The service processor also feeds up a Java applet for displaying the video data and capturing keyboard/mouse actions through a browser at the remote console. Remote control is thus enabled from power up of the main processor continuously through operating system load by the main processor with a single user interface, a single connection, and no special utility requirements at the remote console.

The switch signal controls switching logic configured to receive bus signals from the service processors on each management module. Based on the control signal, one of the service processor bus signals is provided to managed instrumentation on the managed subsystem.

Abstract: A paperless printing system for storing and displaying documents produced by print facilities of a data processing system comprises a docking station in communication with a printer port of the data processing system. The docking station receives, from the data processing system, printer data that defines one or more documents. A portable viewer that is removably coupled with the docking station receives the printer data from the docking station. A rewritable memory within the portable viewer stores the printer data. One or more controls on the portable viewer respond to operator manipulation by causing the portable viewer to utilize the printer data to display a desired portion of the one or more documents at least when the portable viewer is not coupled with the docking station and not in communication with the data processing system. In an illustrative embodiment, the system also includes a printer driver in the data processing system that is associated with the paperless printer.

Abstract: A system, method, and program for establishing modem communication between a master computer system and a plurality of slave computer systems coupled to a common serial communication channel are disclosed. An unique identification number (UIN) is assigned to each slave computer system. The slave system modems are initialized to a “receive mode.” The master computer system directs a session request to the slave computer systems through the common serial communication channel. All slave computer systems receive and respond to the session request by changing each of the modems to the “answer mode.” After all the slave computer systems respond, the master computer system requests communication with a particular slave computer system among the plurality of slave computer systems. The master computer system uses the UIN to establish communication with the particular slave computer system by sending a request from the master computer system specifying the UIN of the particular slave computer system.

Abstract: A method for managing a memory address space in a memory system, the memory system having multiple block address translation entries, each entry defining a portion of the memory address space, including the steps of determining that a received virtual address references a portion of the memory address space not defined by any of the block address translation entries, reallocating at least one of the block address translation entries to define a portion of the memory address space including the received virtual address, and providing a physical address matching the virtual address by using the reallocated block address translation entries.

Abstract: Provides management tools for a System Owner to assure that a personal computer system is secured against access by an unauthorized user by foreclosing the possibility of circumventing system's security protection during an I/O ROM scan. The POST code is designed to prompt for the proper security password prior to allowing any adapter ROM utility to be run. An interrupt service routine will detect key strokes during adapter ROM scan and prior to passing control to the adapter ROM for handling of the keyboard interrupt. Prior to the ROM Scan for the system, the POST code detects whether or not C2 Security is enabled. On some systems, the C2 functionally may not be used and, the system does not consider password protection for the adapter Utilities. If however, the C2 functionality of the system is enabled, the POST code will continue to enable the password protection for the ROM Scan. Once the interrupt service routine is established the ROM scan will begin.

Abstract: A computer system which includes a page mode memory in which a particular piece of data is accessed by first supplying a page or row address, then supplying a column address. These addresses are input to the memory by row address strobe (RAS) signals and column address strobe (CAS) signals. The RAS signals are determined by comparing input CPU addresses with row starting address information stored in registers, each of which corresponds to a memory socket in which a memory module may be installed. An algorithm is described for initializing the memory and its memory controller, including a determination of the starting address information.

Abstract: Apparatus for filtering entrained particulate matter from a gaseous fuel embodies an upstanding housing having a hopper adjacent its lower end for receiving dislodged particulate matter. At least one upstanding, porous tubular filter bag is mounted within the housing. The ends of the filter bag are attached to the housing with its length being greater than the distance between the points of attachment of the ends to the housing. An inlet communicates with one end of the filter bag for introducing a gaseous fluid with particulate matter entrained therein. Particulate matter carried by the gaseous fluid is deposited on the inner surface of the filter bag with cleaned gaseous fluid passing therethrough. An outlet communicates with the housing and discharges the cleaned gaseous fluid.
