A coordinate measuring machine operable to employ pentapod kinematics to determine the absolute position at a measuring point tip by measuring about five axes. The machine comprises a first, bifurcated linkage, a second, trifurcated linkage, and a plurality of elongate struts. First and second ones of the plurality of struts share the first linkage, third, fourth and fifth ones of the plurality of struts share the second linkage, and the first and second linkages are coupled via a handle. The first and second struts are preferably rotatably engaged to the first linkage, and the third, fourth and fifth struts may be rotatably engaged to the second linkage. First through fifth nodes may be provided, each node being slidably engaged to a corresponding one of the first through fifth struts. The nodes may comprise means for measuring the displacement of the corresponding strut relative to the node.

Described herein are techniques for tracking objects (including human body parts such as a hand), namely: 1) two-state transducer interpolation in acoustic phased-arrays; 2) modulation techniques in acoustic phased-arrays; 3) fast acoustic full matrix capture during haptic effects; 4) time-of-flight depth sensor fusion system; 5) phase modulated spherical wave-fronts in acoustic phased-arrays; 6) long wavelength phase modulation of acoustic field for location and tracking; and 7) camera calibration through ultrasonic range sensing.

The invention relates to a method of constructing a building, comprising the step of providing a skeleton for a building wall of the building. The skeleton includes at least upright building elements such as columns or dividing walls. At least one lightweight, heat insulating and fire retarding wall element is placed between each adjacent pair of said columns. The columns are covered to provide substantially closed wall surfaces. The wall surfaces are covered with a covering layer having properties so as to provide fire-resistance to the complete wall. The covering layer on the inside wall surface may include a base layer of modified resin mortar, and a top layer of plaster mortar. The covering layer on the outside wall surface may include a base layer of modified resin mortar and a top layer of mineral mortar. Lightweight, heat insulating floor elements are placed and interconnected, and supported if necessary, and thereafter structural fill-material, such as concrete, is poured onto the floor elements to form a floor. The invention also includes a building, and wall and floor elements.

The invention discloses a method and a device for ecological pond purification treatment of heavy metal-polluted irrigation water. The method comprises the following steps: step 1, selecting a place; step 2, constructing a tertiary ecological pond: performing capacity expansion, deepening, anti-seepage and partition treatment on an existing pond or low-lying land or abandoned land; step 3, constructing an absorption and purification pond: arranging a cement pond at the tail end of the tertiary ecological pond; step 4, putting absorbing materials: filling the materials for absorbing heavy metals at the bottom of the absorption and purification pond; step 5, in a primary ecological pond, planting aquatic plants; 6, in a secondary ecological pond, planting aquatic plants; step 7, in the tertiary ecological pond; planting aquatic plants and performing tertiary purification on the irrigation water. The device comprises the ecological ponds, the absorption and purification pond, a retaining wall, an ecological revetment, anti-seepage geotechnical cloth, a soil layer, a water inlet pipe, a water intake quantity regulating valve, the aquatic plants, the absorbing materials and a water outlet pipe. The device is wide in application scope, high in purification efficiency, simple in structure and easy to operate and manage and effectively reduces the treatment cost of the heavy metal-polluted irrigation water.

A plasma torch of the present invention having a waveguide formed with a vortex air flow collapsing gas supply part includes a waveguide including a microwave irradiating part having an opening formed on one side thereof and irradiating microwaves toward the opening side to generate plasma that vaporizes hydrocarbons supplied into the swirl gas flow formed in front of the opening; and a swirl gas flow disintegrating gas supply portion that supplies a swirl gas flow that collapses a part of the swirl gas flow formed in front of the opening portion Disintegrate gas. Another aspect of the present invention is a plasma torch provided with a waveguide formed with a swirling gas flow collapsing gas supply part, including: a reactor in which a reaction space is formed and includes a raw material injection part for injecting hydrocarbons into the reaction space and a swirl flow generation gas supply part that supplies a swirl flow generation gas that generates a swirl flow to the reaction space; and a waveguide that is connected to the reactor and includes irradiating microwaves to generate gasified hydrocarbons within the swirl flow in the reaction space The microwave irradiating part of the plasma and the supply part of the vortex flow disintegrating gas that is part of the vortex gas flow formed in the reaction space are disintegrated by the vortex flow disintegration gas supply part.

The invention provides a method for separating anti-rotavirus immunoglobulin from a chicken egg. The method comprises the process steps of: transforming the chicken egg at the constant temperature, breaking the egg, adding water for dilution, performing first sedimentation and performing second sedimentation. The adoption of the method disclosed by the invention for separating the anti-rotavirus immunoglobulin from the chicken egg inoculated with rotavirus has the characteristics of simple process, few equipment, low construction cost, capability of ensuring quality and high separation efficiency. The method is suitable for separating the anti-rotavirus immunoglobulin from the chicken egg after the chicken egg is inoculated with the rotavirus.

The invention relates to a hardware switch with good compatibility, two pairs of light guiding grooves in the wall piece of the hardware switch are horizontally distributed, a light guiding strip is arranged in each of the light guiding grooves, a pair of tensioning screw rods is arranged on the bottom edge of the light guiding groove, and an expanding screw rod and a leaking stoppage head are arranged on the top edge of the light guiding groove. According to the hardware switch in the invention, the defect that increase of construction cost and storage cost of articles and construction of alldifferent cover bodies constitute irretrievable cost loss can be effectively avoided.

Device for generating X-ray or XUV radiation includes a device for directing a particle beam of electrically charged particles towards a target. A deflection device for deflecting the particle beam is such that the central axis of the particle beam passes through a first point of deflection and a second point of deflection located at a distance from the first point of deflection in the direction of propagation of the beam. The first and second points of deflection lie on an axis in line with a determined or determinable point of impact of the particle beam with the target. The particle beam can be deflected by the deflection device in the direction of propagation of the beam in the region of one point of deflection independently from of a deflection of the particle beam in the region of the other point of deflection.
