    Abstract: A virtualization infrastructure that allows multiple guest partitions to run within a host hardware partition. The host system is divided into distinct logical or virtual partitions and special infrastructure partitions are implemented to control resource management and to control physical I/O device drivers that are, in turn, used by operating systems in other distinct logical or virtual guest partitions. Host hardware resource management runs as a tracking application in a resource management “ultravisor” partition, while host resource management decisions are performed in a higher level command partition based on policies maintained in a separate operations partition. The conventional hypervisor is reduced to a context switching and containment element (monitor) for the respective partitions, while the system resource management functionality is implemented in the ultravisor partition. The ultravisor partition maintains the master in-memory database of the hardware resource allocations and serves a command channel to accept transactional requests for assignment of resources to partitions. It also provides individual read-only views of individual partitions to the associated partition monitors. Host hardware I/O management is implemented in special redundant I/O partitions. Operating systems in other logical or virtual partitions communicate with the I/O partitions via memory channels established by the ultravisor partition. The guest operating systems in the respective logical or virtual partitions are modified to access monitors that implement a system call interface through which the ultravisor, I/O, and any other special infrastructure partitions may initiate communications with each other and with the respective guest partitions. The guest operating systems are modified so that they do not attempt to use the “broken” instructions in the x86 system that complete virtualization systems must resolve by inserting traps.

    Abstract: A light modulator includes elongated elements arranged parallel to each other. In a first diffraction mode, the light modulator operates to diffract an incident light into at least two diffraction orders. In a second diffraction mode, the light modulator operates to diffract the incident light into a single diffraction order. Each of the elongated elements comprises a blaze profile, which preferably comprises a reflective stepped profile across a width of each of the elongated elements and which produces an effective blaze at a blaze angle. Alternatively, the blaze profile comprises a reflective surface angled at the blaze angle. Each of selected ones of the elongated elements comprise a first conductive element. The elongated elements produce the first diffraction when a first electrical bias is applied between the first conductive elements and a substrate. A relative height of the blazed portions are adjusted to produce the second diffraction when a second electrical bias is applied between the first conductive elements and the substrate. In an alternative embodiment, each of the elongated elements includes the first conductive element and multiple elongated elements are arranged in groupings, where each of the groupings includes at least three of the elongated elements. When the multiple elongated elements are at a first height, the incident light reflects from the elongated elements. When relative heights of the multiple elongated elements are adjusted by applying individual electrical biases between the first conductive elements and the substrate, the incident light diffracts into the single diffraction order.

    Abstract: A grating light valve with reduced surface charging is disclosed. Surface charging is measured by the propensity an insulating surface to accept and transport a charge. The grating light valve of the instant invention has a plurality of spaced and movable ribbons formed from Si3N4 coupled to a substrate structure formed of SiO2. A portion of the ribbons are moved to alternate between conditions for constructive and destructive interference with an incident light source having a wavelength &lgr; by applying the appropriate switching voltages across the portion of ribbons and the substrate structure. When charging occurs on surfaces of the grating light valve, the switching voltages required to operate the grating light valve are shifted and diminishing the performance of the grating light valve. By drying silicon-based surfaces of the grating light valve and exposing the silicon-based surfaces of the grating light valve to a Nitrogen-rich pacify gas environment, the surfaces of the grating light valve exhibit reduced charging and consistent response to applied bias voltages. In the drying step, residual water or moisture is removed from the surfaces by elevating the temperature of the grating light valve structure in a vacuum environment. Preferably, the drying is carried at temperatures of 250 degrees Celsius or greater and at vacuum pressures of 10−6 Torr or less. After the surface of the grating light valve are dried, the surfaces are exposed to the Nitrogen-rich pacifying gas environment at ambient temperature. Presumably, the Nitrogen-rich pacify gas environment blankets the silicon-based surfaces of the grating light valve with adsorbed, physisorbed, or chemi-adsorbed Nitrogen and thus reduces the propensity of those surfaces to accept water or moisture, which is believed to facilitate the charging. After the surfaces of the grating light valve are treated according to the current invention, charging of the surface remains low and stable even for several days in open air conditions.

    Abstract: When fumigating a bulk particulate commodity stored in a top-vented vertical silo by slowly passing a gas containing a low concentration of a gaseous fumigant through the bulk mass, differences between the temperature, T.sub.g, in the bulk mass and the ambient temperature, T.sub.a, outside the silo cause a "chimney effect" within the silo, and possible unwanted dilution of the fumigant. The chimney effect also occurs in other top-vented storage structures containing particulate commodities. To overcome the chimney effect, the fumigant-containing gas is supplied through a duct to the base of the storage structure at a flow rate Q.sub.f (in m.sup.3 sec.sup.1) determined by the relationship ##EQU1## where g is the acceleration due to gravity (approximately 9.8 m sec .sup.2); P.sub.a is the atmospheric pressure expressed in Pascals; R.sub.a is the gas constant for air (=287 J kg.sup.-1 K.sup.-1); T.sub.a is in K; T.sub.g is also in K; R is a resistance factor (in Pascals sec m.sup.-2) which depends upon the nature of the commodity in the storage structure; and A is the horizontal cross-sectional area of the storage structure, in square meters. This technique can also be used to maintain effective fumigation of a plurality of storage structures in a storage facility, from a single source of gaseous fumigant.
