Abstract: A data recording system, such as a magnetic recording hard disk drive, has a recording medium in which the data tracks have pseudo-random binary sequences for the servo information used to control the position of the recording head. A first pseudo-random binary sequence (PRBS) and a second PRBS identical to the first PRBS but shifted by a portion of the period of the first PRBS are located between the track boundaries in alternating tracks in a first region of the servo pattern and between the track centers in alternating tracks in a second region spaced along the track from said first region. A servo decoder has two correlators, one for each PRBS. Each correlator outputs a dipulse when its PRBS repeats. The difference in amplitude of the dipulses represents the head position signal. The dipulses also control the amplifier for the signal read back by the head and the timing of the track identification (TID) detector.

Abstract: A system and method for facilitating data communications in a device network are provided. An integrated information system includes a number of premises-server computing devices, a central communication device, and a number of client computing devices. Each client computing device communicates with the central communication device to request access to device data from the premises-server computing devices. Once access rights are established, the client computing devices communicate directly with specific premises-server computing devices. A command application resident on each premises-server computing device, referred to as the command proxy, administers the direct flow of data between the computing devices.

The bucket has a wide, relatively shallow configuration wherein the rear wall has a height greater than the adjacent side wall portions and respective junctions between the floor and side walls are formed with an arcuate inner surface and there is an arcuate taper between the floor and the top of the rear wall.

Abstract: An excavator tooth system comprises a mounting nose having a projecting spigot and a wear member (12) having at one end a socket (18), the socket (18) being defined by spaced side walls and upper and lower walls converging from a rearwardly facing socket opening to a forward end of the socket. Each of the upper and lower walls comprises a forward bearing face (8a) and a rear bearing face (7a) separated by a forwardly convergent intermediate face. The front and rear bearing faces (8a,7a) are substantially parallel to a longitudinal axis (50) of the wear member and engage corresponding bearing faces (8,7) in said spigot.

Abstract: A system and method for asynchronously processing video images are provided. A video processing computing device includes one or more video capture boards in communication with a number of image capture devices, such as video cameras. The video image processing computing device includes a video collection application that is operable to instruct the video capture board to acquire video data and store the data in a shared memory area. The video processing computing device also includes a video processing application that is operable to acquire the stored video from the shared memory area and process the video data. By utilizing a shared memory area, the video collection application and the video processing application can process data asynchronously.

Abstract: A method and system utilizing one or more data generating computing devices as default data warehouses in the event of a primary data warehouse failure are provided. A data warehouse provides an environment in which data from one or more data servers in one or more locations, or premises, is aggregated in a central database. In the event of a system failure, in which communication between the data warehouse and one or more servers is disrupted, a warehouse ticket file, stored on secure, distributed ticket servers, is used to identify and initialize at least one of the data servers as a failover data warehouse. Once communication between the premises and its primary data warehouse is restored, the data collected during the failover is transferred to the primary data warehouse and purged from the failover data warehouse.
