Abstract: Disclosed is a method for processing an arbitrary collection of objects, forming a complex structure, into a hierarchy of bounding volumes, from a root volume bounding all objects, to sub-volumes bounding individual objects or assemblies thereof, for use as successive approximations to said objects in a computer generated display. The method includes the first step of creating a bounding volume for each of the objects. Selected bounding volumes are then processed through a combining algorithm determining whether or not, based upon a geometric relationship between the bounding volumes and the higher level, root volume, the selected bounding volumes can be combined. If it is determined that the bounding volumes can be combined, a new bounding volume is created with the combined volumes comprising sub-volumes thereof. This process systematically repeats and attempts to combine all sub-volumes. The combining algorithm preferably allows a combination if the volumes of the combination of the sub-volume is smaller than a fixed percentage of the parent volume. When a pair can combine, it is replaced by a box bounding volume that contains the pair as sub-volumes, and the process continues. In this way, a bounding volume hierarchy for all objects and assemblies within a complex structure is created.

Abstract: Methods and apparatus for releasing energy from hydrogen atoms (molecules) by stimulating their electrons to relax to quantized lower energy levels and smaller radii (smaller semimajor and semiminor axes) than the "ground state"  by providing energy sinks or means to remove energy resonant with the hydrogen energy released to stimulate these transitions. An energy sink, energy hole, can be provided by the transfer of at least one electron between participating species including atoms, ions, molecules, and ionic and molecular compounds.  In one embodiment, the energy hole comprises the transfer of t electrons from one or more donating species to one or more accepting species whereby the sum of the ionization energies and/or electron affinities of the electron donating species minus the sum of the ionization energies and/or electron affinities of the electron accepting species equals approximately mX27.21 eV (mX48.6 eV) for atomic (molecular) hydrogen below "ground state" transitions where m and t are integers. The present invention further comprises a hydrogen spillover catalyst, a multifunctionality material having a functionality which dissociates molecular hydrogen to provide free hydrogen atoms which spill over to a functionality which supports mobile free hydrogen atoms and a functionality which can be a source of the energy holes. The energy reactor includes one of an electrolytic cell, a pressurized hydrogen gas cell, and a hydrogen gas discharge cell. A preferred pressurized hydrogen gas energy reactor comprises a vessel; a source of hydrogen; a means to control the pressure and flow of hydrogen into the vessel; a material to dissociate the molecular hydrogen into atomic hydrogen, and a material which can be a source of energy holes in the gas phase. The gaseous source of energy holes includes those that sublime, boil, and/or are volatile at the elevated operating temperature of the gas energy reactor wherein the exothermic reaction of electronic transitions of hydrogen to lower energy states occurs in the gas phase.

Abstract: In an optical data storage medium with a storage area formed from a tranparent, homogeneous base material and with a number of optically active structures at one side of the storage area, the optically active structures are diffractive optical elements which can focus a beam of light incident on the storage area on to one or more points in the storage area and/or a redirected beam of light or emitted light radiation from this or these points on to a point outside the optical storage medium. During writing/reading of data in the storage medium, the diffractive optical elements are used for focusing the write/read beam in order to generate a data carrying structure or read data stored in such a data carrying structure, respectively. By exploiting the special optical properties of diffractive optical elements, it is possible to achieve parallel writing/reading of data, possibly in several parallel storage layers in the optical storage medium or randomly distributed therein, the optical storage medium thus providing a genuine volumetric storage and a corresponding genuine volumetric accessing of the stored data.

Abstract: A system and method for controlling vibration of an axially rotatable mandrel useable for winding sheet material including stretch film thereabout. The system includes first, second and third roller members rotatably contactable with the mandrel and sheet material wound thereabout. The roller members are arranged about the mandrel axis so that the mandrel and any sheet material wound about the mandrel is supportably captured between the roller members to prevent or at least substantially reduce vibration of the rotatable mandrel. At least the first and second roller members are biasable toward the mandrel with pneumatic pressure from corresponding air over oil cylinders, and the first and second roller members are movable away from the mandrel against hydraulic resistance from the corresponding air over oil cylinders to accommodate sheet material wound increasingly about the mandrel. In one configuration, first and second mandrels are rotatably coupled to a rotatable turret that alternately positions the mandrels relative to a power driven lay-on roll, wherein each mandrel has at least one corresponding set of first and second roller members which cooperate with the lay-on roll to prevent vibration of the rotating mandrel.

Abstract: A voice messaging system enables a callee to specify a retention time for retaining a stored voice message from a caller. The system then automatically deletes the stored voice message after the expiration of the retention time. In one embodiment, the caller is able to specify one retention time when the message is first recorded, and the callee can change that retention time when the message is retrieved. If the message is not retrieved by the callee before the caller-specified retention time expires, the system will automatically delete the message. In one embodiment, a callee can also assign a retention time to an outgoing voice message for playback to subsequent callers. The present invention improves the operations of a voice messaging system with limited memory resources, by reducing the chances that the system's memory will become filled with old messages which would leave the system unable to store new messages from callers.

Abstract: In a particularly reliable and flexible process for simulating the behaviour of a technical installation in which a medium existing in a plurality of phases (W, D) circulates in a partial region, according to the invention a heat flow (Q fg) and a mass flow (M fg) between two phases (W, D) are detected by means of a linear combination of differences from derivations of the entropy (S f, S g) of the phase concerned (W, D) according to the internal energy (U) or the mass (m m, m g) of the phase concerned. The linear coefficients (L ij) of an equation system derived from the linear combinations form a symmetrical matrix. As an application of irreversible thermodynamics to the simulation process there arise on the one hand representations for the mass and heat flows (M fg, Q fg) as a function of "forces" and on the other relations between the flows (M fg, Q fg) based on the Onsager relation.
