Abstract: A plurality of computers in a network (503-505) each have a processor and a non-volatile data storage device (500-502) such as a hard disk, a raid array, or the like. Each data storage device is divided into a first data storage area (203-205) and a second data storage area (509-511). The first data storage area is reserved for use by at least one processor to which it is assigned, whereas the second data storage area is hidden from use by the file system of the computer, and is used to store replicated data of other ones of the plurality of computer entities. In the event of failure of any one of the data storage devices, data can be recovered from the second data storage areas of the other data storage devices.

Abstract: A pneumatic radial tire having in axial cross-section a highly curved tread is reinforced by a breaker assembly with improved resistance to breaker edge looseness. The breaker assembly includes one breaker ply which extends between two bead regions and has its edges disposed between a carcass main portion and a carcass turn-up portion. An improved single-stage method may be employed for building the tire.

Abstract: Data are stored on magnetic tape along successive tracks extending obliquely across the tape, in each of several areas including a lead-in area, a data area and an end-of-data (EOD) area. Each track comprises successive blocks or fragments of data, and each fragment has a compact header containing a synchronization byte, six information bytes and two parity bytes. The information bytes include a fragment ID, an area ID sub code identifying the area in which the fragment is located, and various other sub codes relating to logical structure of the data. The inclusion of an area ID sub code and logical structure sub codes in the (compact) header of every fragment facilitates reliable searching of the data stored on the tape at high tape advance speeds.

Abstract: A hand-held water purification system includes a pen-light sized ultraviolet lamp that is enclosed in a quartz cover and is powered by a battery and associated ballast circuitry. The battery and ballast circuitry are connected to the lamp by switches that are under the control of a liquid-level sensor. The sensor connects the battery, the ballast circuitry and the lamp once the sensor determines that the ultraviolet lamp is fully immersed in the water. If the container that holds the water is relatively large, the lamp and quartz cover end of the system are used to stir the water, to ensure that all of the water comes sufficiently close to the ultraviolet lamp.

The reflecting surfaces are parallel to each other and orthogonal to the common rotation axis.

Abstract: A hose assembly is provided for transmitting liquid fuel between the fuel tank of a highway truck and the fuel tank of an airport refueler. The assembly comprises inner and outer hoses. The inner hose transmits liquid fuel. A sealed passage is formed between the inner and outer hoses. Each end of the hose assembly is connected to a respective port for transferring the fuel between the highway truck fuel tank and airport refueler tank. The assembly includes at least one sensor port for connecting the passage to sensing means to detect leakage from the inner hose to the passage. A leakage sensing system is coupled to the sensor port for detecting leakage of fuel from the inner hose to the passage and for generating sensor signals. The leakage sensing system includes: (1) a pressure sensor for detecting a change in pressure within the passage, and (2) a liquid sensor for detecting the presence of liquid within the passage.

Abstract: A speech coding system robust to frame erasure (or packet loss) is described. Illustrative embodiments are directed to a modified version of CCITT standard G.728. In the event of frame erasure, vectors of an excitation signal are synthesized based on previously stored excitation signal vectors generated during non-erased frames. Specifically, the decoder generates and stores samples of a first excitation signal in a memory, and then, in response to a signal indicating a frame erasure, the decoder synthesizes a second excitation signal based on the previously stored samples. In particular, the second excitation is synthesized by correlating a first subset of the stored samples with a second subset thereof, identifying a set of stored excitation signal samples based on the correlation, and synthesizing the second excitation signal based on the identified samples. Finally, the decoder then filters the second excitation signal to synthesize a signal reflecting human speech.

Abstract: An optical scanning system wherein infrared energy radiating from an object is directed to a Porro prism, such Porro prism being rotatable about the boresight axis of the optical scanning system so that the image of the object rotates, in the image plane of such system about its boresight axis, at an angular rate twice that of the Porro prism. A linear array of infrared detector elements is disposed in the image plane radially from the boresight axis of the scanning system. The angular deviation of the object from the boresight axis of the scanning system is measured by determining: (1) the angular position of the Porro prism when one, or more, of the infrared detector elements in the linear array is energized; and (2) which one, or ones, of such elements is energized.
