Manufacturing method of three-dimensional food by rapid prototyping

InactiveUS20080260918A1Produce rapidly and convenientlyEnhance artistic look and valueAdditive manufacturing apparatusFood coatingThree dimensional modelComputer Aided Design
This invention discloses a manufacturing method for producing three-dimensional food in a very short time without using a mold. The key technology is to establish a figure or word character in a computer-aided design (CAD) software such as CATIA, Pro / E, I-Deals, Solidwork, and AutoCAD or use a built-in figure and word of the Window system. The figure or word character is built into a three-dimensional model and transformed into a file with an *.stl format. Finally, a rapid prototyping (RP) machine is used to build the 3D food, and then the finished goods of the 3D food are produced. The invention promotes the food manufacturing method from 2D to 3D and accomplishes a substantial progress on the application of rapid prototyping.

Surgical drill guide and index system

A surgical drill guide for installing dental implants with predetermined angular alignment and rotational orientation for a dental prosthesis, formed of:a. a base part formed to correspond generally to the shape and contour of a patient's upper or lower mouth, the base part having peripheral edges and having opposite tissue and mouth sides and at least one drill guide hole extending through the base part from the tissue side to the mouth side, each of the drill guide holes having a central axis at a predetermined angular orientation relative to the mouth side and having lateral location relative to the peripheral edges, andb. a set of rotational position indicators on the tissue and mouth sides respectively of the base part for each of the drill guide holes, the rotational position indicators of each set being at the same rotational position about the central axis of the drill guide hole.

Method and apparatus for symmetric-key encryption

A symmetric-key cryptographic technique capable of realizing both high-speed cryptographic processing having a high degree of parallelism, and alteration detection. The invention includes dividing plaintext composed of redundancy data and a message to generate plaintext blocks each having a predetermined length, generating a random number sequence based on a secret key, generating a random number block corresponding to one of the plaintext blocks from the random number sequence, outputting a feedback value obtained as a result of operation on the one plaintext blocks and the random number block, the feedback value being fed back for using in the operation on another plaintext blocks, and performing an encryption operation using the one plaintext blocks, random number block, and feedback value.

Hybrid method for dental implant treatment planning

A hybrid method for dental implant treatment planning and a corresponding approach to make a surgical guide. After digital treatment planning is performed with CT scan data, a master model is created, which embodies the patient anatomy and entire treatment plan. Jaw bone, tooth surfaces, soft tissues and nerves are all contained by the master model. The plan details including implant sizes and positions, surgical guide drill options, as well as the choice of a surgical kit, are all conveyed by the master model. Meanwhile, models of specially designed “implant inserts (or replicas)” are also generated, which have one end that fits into the implant holes on the master model and another end to make the surgical guide. The master model and inserts are manufactured with rapid prototyping technology. A surgical guide is later on made from them with conventional lab processes. A main characteristic of this approach is that the master model and the inserts are the physical embodiment of a virtual treatment plan. With them, the surgeons can continue the treatment planning for operations like tooth extractions and bone modifications before making the surgical guides. Therefore the treatment planning workflow is a combination of digital treatment planning and a physical model based planning, in other words, a hybrid approach. A differentiator in this invention is the generation of a closed solid model of the soft tissue, as part of the master model, from the scan data. This approach can be applied to create both bone-borne and tissue-borne surgical guides with low cost process, which is a big advantage over other approaches.

Single and double-gate pseudo-fet devices for semiconductor materials evaluation

InactiveUS20050092985A1Obtain electrical propertyFast techniqueTransistorSemiconductor/solid-state device testing/measurementState densityStrained silicon
Several methods and structures are disclosed for determining electrical properties of silicon-on-insulator (SOI) wafers and alternate versions of such wafers such as strained silicon:silicon / germanium:-on-insulator (SSGOI) wafers. The analyzed electrical properties include mobilities, interface state densities, and oxide charge by depositing electrodes on the wafer surface and measuring the current-voltage behavior using these electrodes. In a single gate structure, the source and drain electrodes reside on the wafer surface and the buried insulator acts as the gate oxide, with the substrate acting as the gate electrode. In a double gate structure, an oxide is used on the upper surface between the source and drain electrodes and an additional metal layer is used on top of this oxide to act as a second gate electrode. Light of broad spectrum or specific wavelength may be used to alter electrical carrier densities in the region between the electrodes to further analyze the electrical properties of the material, or alternatively, the device can be used as a detector of light having a wavelength shorter than the bandgap wavelength of the Si surface.
