1240 results about "Computer Aided Design" patented technology

Computer-aided design (CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design. CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The term CADD (for Computer Aided Design and Drafting) is also used.

System and method for automated placement or configuration of equipment for obtaining desired network performance objectives and for security, RF tags, and bandwidth provisioning

A method is presented for determining optimal or preferred configuration settings for wireless or wired network equipment in order to obtain a desirable level of network performance. A site-specific network model is used with adaptive processing to perform efficient design and on-going management of network performance. The invention iteratively determines overall network performance and cost, and further iterates equipment settings, locations and orientations. Real time control is between a site-specific Computer Aided Design (CAD) software application and the physical components of the network allows the invention to display, store, and iteratively adapt any network to constantly varying traffic and interference conditions. Alarms provide rapid adaptation of network parameters, and alerts and preprogrammed network shutdown actions may be taken autonomously. A wireless post-it note device and network allows massive data such as book contents or hard drive memory to be accessed within a room by a wide bandwidth reader device, and this can further be interconnected to the internet or Ethernet backbone in order to provide worldwide access and remote retrieval to wireless post-it devices.

Direct write process and apparatus

A direct write process and apparatus for fabricating a desired circuit component onto a substrate surface of a microelectronic device according to a computer-aided design (CAD). The process includes (a) providing a support member by which the device is supported while being fabricated; (b) providing a chamber for containing a precursor fluid material under a substantially constant pressure differential relative to the ambient pressure, with the precursor fluid material having a viscosity no less than 10 cps; (c) operating an inkjet-based dispensing head with a control valve or actuator for dispensing and depositing minute droplets of the precursor fluid material onto the substrate surface; (d) energy- or heat-treat the deposited precursor fluid material for converting it to the desired active or passive component; and (e) operating a machine controller for generating control signals in response to the CAD coordinates for controlling the position of the dispensing head relative to the support member in response to the control signals to control dispensing and depositing of the precursor material to form the desired component. The process is useful for depositing a wide range of component materials onto an electronic device, including conductor, resistor, capacitor, dielectric, inductor, antenna, solar cell electrode, battery electrode, interconnect, superconductor, sensor, and actuator element materials.

Manufacturing methods and systems for rapid production of hearing-aid shells

Methods, apparatus and computer program products provide efficient techniques for designing and printing shells of hearing-aid devices with a high degree of quality assurance and reliability and with a reduced number of manual and time consuming production steps and operations. These techniques also preferably provide hearing-aid shells having internal volumes that can approach a maximum allowable ratio of internal volume relative to external volume. These high internal volumes facilitate the inclusion of hearing-aid electrical components having higher degrees of functionality and/or the use of smaller and less conspicuous hearing-aid shells. A preferred method includes operations to generate a watertight digital model of a hearing-aid shell by thickening a three-dimensional digital model of a shell surface in a manner that eliminates self-intersections and results in a thickened model having an internal volume that is a high percentage of an external volume of the model. This thickening operation preferably includes nonuniformly thickening the digital model of a shell surface about a directed path that identifies a location of an undersurface hearing-aid vent. This directed path may be drawn on the shell surface by a technician (e.g., audiologist) or computer-aided design operator, for example. Operations are then preferably performed to generate a digital model of an undersurface hearing-aid vent in the thickened model of the shell surface, at a location proximate the directed path.

The invention discloses a neutral zone complete denture manufacturing method based on a Computer Aided Design/RapidPrototyping (CAD/RP) technology. The method comprises the following steps: a complete denture artificial tooth three-dimensional image database is established on the basis of the parameterized positioning; the data of upper and lower edentulous jaws with centric relation and neutral zone jaw is collected on the basis of the three-dimensional laser scanning technology with spatial position relation; the complete denture artificial articulation conforming to the theory of neutral zone and complete denture balanced occlusion tooth arrangement is designed on the basis of reverse engineering software, the gum and the base conforming to the complete denture neutral zone theory and the aesthetic principle are designed on the basis of the reverse engineering software; a complete denture flask is designed and processed on the basis of the CAD/RP technology; and the complete denture restoration is finished through the manual tooth inserting and the adhesive applying. The invention creates the concept of a two-step method, finishes the manual tooth arrangement and the wax pattern preparation with the highest technical content and the most complex operation in the traditional fabrication by using the computer and rapid prototyping technology, can finish the full fabrication of the complete denture only by being finally aided with the simple manual step, i.e., the second step of the two-step method, greatly simplifies the complex working procedures of the traditional handwork process, improves the efficiency and the accuracy of restoration and realizes the transformation of the designing and manufacturing process of the complete denture from the manual mode to the digital mode.
