Abstract:

An apparatus and method for fabricating a three dimensional model from a composite model formed or a plurality of successive layers of model material and sacrificial mold material. Each successive layer is constructed by depositing, drop-by-drop, at least one line of sacrifical mold material delineating at least one boundary of the model material within the layer and thereafter depositing the model material onto all delineated regions of the layer by spray deposition. Each successive layer is completed by a planing process which removes the undesired thickness of both the sacrificial and the model materials. Following completion of the composite model, the sacrificial mold material is removable from the composite model, by a process effecting only the sacrificial mold material, to produce the three dimensional model. A device, for depositing the model material at the rate faster than the rate that the mold material is deposited, is also described.

International Classification:

B05D 3/00

US Classification:

427271

Abstract:

A method for fabricating a three dimensional model by fabricating a composite model formed of a plurality of successive layers comprised of one or more materials wherein each successive layer is formed by depositing at least first material delineating boundaries of at least one first area of the layer by a drop-by-drop deposition and depositing at least a second material over the layer by a rapid deposition method, and may include the deposition of a third material by a drop-by-drop or rapid deposition method and will include planing the layer to a uniform thickness and selectively removing the first and second materials, and third material if present, by successive removal methods, each of which effects only one of the materials.

International Classification:

US Classification:

427289, 118 72

Abstract:

A method of fabricating a three dimensional model from a composite model formed by a plurality of layers. The composite model comprises at least one shell material encasing and enclosing a build material. The method comprises the steps of (1) depositing a build layer of the build material onto a preceding layer, (2) removing a selected area of the build material from the deposited build layer; (3) depositing the shell material in any removed selected area of the build material; and (4) reducing the build layer to a desired final thickness for supporting a next build layer. Then repeatedly repeating steps (1) through (4) for each build layer until the composite model is completed. Finally, the undesired extraneous material, and possibly the shell, are removed to obtain the final model.

US Classification:

358493

Abstract:

A high quality, relatively inexpensive rotary scanner provides both transmission and reflection scanning of documents mounted on a rotary drum. The drum translates with respect to an imaging lens located adjacent the drum and on the exterior thereof. A first illuminating element surrounding the imaging lens illuminates the document on the drum for reflection scanning; a second illuminating element mounted on a cantilevered arm extending along the axis of the drum illuminates the document for transmission scanning. Focusing of the image is performed either automatically or under the control of the user. A high resolution and wide dynamic range is provided by a set of photomultiplier tubes which receive light from the imaging lens by way of an aperture wheel which provides apertures of selectable size in accordance with the desired resolution. User replaceable lamp modules allow the precise positioning of high intensity replacement lamps without need for a technician.

Abstract:

A system for controlling a load including a plurality of LEDs includes a timing circuit, an encoder and a configuration switching circuit. The timing circuit generates time-off switching points and time-on switching points. The encoder generates a load voltage by modifying a rectified line voltage using the time-off switching points and the time-on switching points. The configuration switching circuit determines a maximum voltage of a line voltage input to the driver system, selects a configuration for the plurality of LEDs based on the maximum voltage, communicates the configuration for the plurality of LEDs to the load, dynamically reconfigures the configuration for the plurality of LEDs based on the modified rectified line voltage, the dynamically reconfiguration of the configuration including changing at least one of the first quantity of LEDs in electrically coupled in series and the second quantity of LEDs electrically coupled in parallel.
