Abstract:
Low NOx burners for the combustion of gaseous, liquid and solid fuels. The fluid dynamic principle of radial stratification by the combustion of swirling flow (72, 74, 76) and a strong radial gradient of the gas density in the transverse direction to the axis of flow rotation is used to damp turbulence near the burner (62) and hence to increase the residence time of the fuel-rich pyrolyzing mixture before mixing with the rest of the combustion air (22, 34, 42) to effect complete combustion.
Abstract:
Removal of body tissue with a long pulsed lasers is achieved such that sufficient energy to remove tissue is transmitted to the desired body without damaging an optical fiber transmitting the laser radiation. Pairs of pulses having the same or different wavelengths are coupled to more effectively remove tissue from the surgical site.
Abstract:
A method and apparatus for generating a high power beam of light is described in which individual laser pixel elements are laterally defined and isolated in a wafer of solid state gain medium material and mirrors are formed on each side of the wafer to produce an optical cavity resonator. An array of diode lasers is used to pump adjacent pixels to stimulate light emission by each pixel.
Abstract:
An apparatus (10) for estimating the solution to a finite element analysis and/or regularization equation, the apparatus including means (12) for generating a pyramid representation of input data, each level of the pyramid representation corresponding to a different set of similar eigenvectors; means (24) for multiplying at least one of the levels of the representation by a weight derived from the eigenvalue associated with the set of eigenvectors for the level to generate a weighted pyramid representation; and means (14) for collapsing the weighted pyramid representation to generate an estimated solution to the equation.
Abstract:
Fluid flow is simulated by a massively parallel data processor having combinational logic for processing collision rules at lattice sites. Following collision processing, particle representations are moved to different sites dependent on direction and velocity of the particles. The collision rules are based on collisions of particles positioned at sites of a three-dimensional lattice. Particle representations identify particles of plural energy levels, and the collision rules allow for transfer of energy between particles. Particle representations relate to particles which move along four-dimensional face-centered hypercube lattices which project to the three-dimensional lattice.
Abstract:
A class of switching networks is comprised of expansive logical clusters and/or dispersive logical clusters. These clusters are of low degree. The class of networks include multibutterfly networks as well as multi-Benes networks. These networks provide for fault tolerance and routing and for efficient routing. Moreover, routing is provided in a non-blocking fashion.
Abstract:
An image interpolator (2) for converting an original image into an enhanced image, the interpolator (2) including rule logic for embodying a rule specifying how pixel patterns associated with first subband image data (Gi+1) transform into corresponding pixel patterns associated with second subband image data (L1), the first and second subband image data (Gi+1, Li) being derived from a reference image (Gi); and conversion logic for generating the enhanced image from the original image based upon the rule.
Abstract:
Damping structural vibrations by applying a multiplicity of discrete untuned passive dampers (25) to a structure (12). Each passive damper includes a damping element (28) and a damping mass (26), and the damping element provides damping generally in proportion to the relative velocity occuring between the mass and a point of attachment of the damper to the structure. The damping coefficients of the damping elements are selected so that the dampers increase the effective loss factor of the structure. The passive dampers each have a damping mass which is supported such that the dampers experience an undamped natural frequency below the resonant frequencies and the frequency range of the structure.
Abstract:
A surface probe is described for use in detecting the degree of degeneration in mammalian tissue. The probe comprises a means for applying to a surface of mammalian tissue a force which affects an electrokinetic parameter of the tissue. The probe further comprises a means for detecting an electrokinetic parameter. The effect on electrokinetic parameters is indicative of the amount of a charged species involved in tissue degeneration. A method is also described for comparing the detected electrokinetic parameters value to normal values for types of tissue examined.
Abstract:
An optical system (10) has an optical package (28) operable with an acquisition, tracking and pointing network (29), the optical package (28) including a coupling device (34/35) and an optical fiber (22/22a) and acting to carry optical signals and to transfer then into/ou of the fiber (22/22a) the fiber (22/22a) transferring the signals from/to a transmitter/receiver (31/26). An aspect of the invention includes a coupling device (34) with a housing (36) to which is affixed a flexure (50). A fiber (22) extends along the flexure (50) and terminates about one end of flexure (50). An actuator (42, 44) is coupled between the flexure (50) and the housing (30). The flexure (50) is coupled to a detector (66, 68) to cooperate with the actuator (42, 44) for driving the flexure (50). The transmitter/receiver (31/26) cooperates with the acquisition, tracking and pointing network (29) to control the coupling device (34). Both coherent or non-coherent detection may be employed. Various features and embodiments are described.
