Abstract: A 3-D printer includes build and support material development stations that electrostatically transfer build material and support material to an ITB. The ITB transfers a layer of build and support material to a platen each time the platen contacts one of the layers on the ITB, to successively form a freestanding stack of the layers on the platen. A sensor is positioned to generate a topographic measurement of the layer on the platen, and an aerosol applicator is positioned to propel build and support material on to the layer on the platen. The aerosol applicator controls the build and support material being propelled, based on the topographic measurement from the sensor through a feedback loop, to adjust the amount and location of the build material and the support material propelled on to the layer, and thereby control the flatness of surface topology of the layers in the freestanding stack on the platen.

A dispenser is positioned to deposit a leveling material on the layer on the platen, and a mechanical planer is positioned to contact and level the leveling material on the layer on the platen to make the top of the leveling material parallel to the flat surface of the platen.

Abstract: A system includes a communications system and at least one processor coupled with the communications system and with a non-transitory processor-readable medium storing processor-executable code. The communications system is configured to receive measured air data from an air sensor system and receive flight data from a flight monitoring system. The air data is indicative of at least one air characteristic of an environment surrounding an aircraft. The flight data is indicative of at least one flight characteristic of the aircraft. The processor-executable code causes the at least one processor to detect a failed state of the air sensor system based on the measure air data and the flight data, estimate air data in response to detecting the failed state of the air sensor system, and provide the estimated air data to at least one of a display device and an automated flight control system.

Abstract: 3-D printers include an intermediate transfer surface that transfers a layer of material to a platen each time the platen contacts the intermediate transfer surface to successively form a freestanding stack of layers of the material on the platen. A sensor detects the thickness of the layer on the platen after a fusing station fuses the layer. A feedback loop is electrically connected to the sensor and a development station (that includes a photoreceptor, a charging station providing a static charge to the photoreceptor, a laser device exposing the photoreceptor, and a development device supplying the material to the photoreceptor). The exposure device adjusts the intensity of light exposed on the photoreceptor, based on a layer thickness measurement from the sensor through the feedback loop, to control the thickness of subsequent ones of the layers transferred from the intermediate transfer surface to the freestanding stack on the platen.

Abstract: A system and method are provided for implementing a unique electrophotographic layered manufacturing scheme for creating higher fidelity electrophotographic composite laminate layers using tri-level electrophotography or electrostatic imaging scheme as a process for rendering individual laminate layers to be built up to form and/or manufacture three-dimensional objects, parts and components as 3D objects. A multi-stage 3D object forming scheme is described involving steps of multi-component laminate forming in a particularized electrophotographic layer forming process. This process renders a part component and a support component precisely next to one another with a single exposure by an exposing device to form a latent image of variable discharge voltages. Multiple toner product sources are used to dispose part component toner and support component toner in the forming of the multi-component laminate layer.

Abstract: A method of preparing a nucleic acid sample with target enrichment uses a reaction vessel (11), within which is added a chelating agent to a sample with heating to about 99° C. to provide a crude lysate. A PNA probe is provided at a concentration sufficient for binding and capture of discernible levels of target nucleic acid. The PNA probe may be attached to beads (26) which are initially embedded in a wax body (17) and are released during the heating so that they are free to move and come into contact with the PNA probe and target DNA. After binding has occurred, the beads are magnetically attracted back into a pocket (16) along with the wax (17), which is allowed to solidify before they are removed from the reaction vessel.

Abstract: The present invention pertains to a process for depositing multi-component and nanostructured thin films. Various parameters are monitored during the process to produce the structure of the thin films, on one hand the residence time of the gas mixture in the reactor is controlled by the pumping rate, on the other side to generate the plasma direct current (DC) or radio frequency (RF) sources are used, plus the combination of three unbalanced magnetrons allows alternative emission of elements that make up the multi-component and nanostructured films. The process is monitored by an optical emission spectrometer (EOE) and a Langmuir probe (SL), the EOE can follow the emission corresponding to the electronic transitions of atoms and molecules in the plasma. Emissions occur in the visible, infrared and ultraviolet domains. The relationships between spectral networks of different elements have been identified that ensure structural characteristics of thin films.
