484 results about "Plotter" patented technology

A plotter is a computer printer for printing vector graphics. Plotters draw pictures on paper using a pen. In the past, plotters were used in applications such as computer-aided design, as they were able to produce line drawings much faster and of a higher quality than contemporary conventional printers, and small desktop plotters were often used for business graphics. Although they retained a niche for producing very large drawings for many years, plotters have now largely been replaced by wide-format conventional printers.

Scalable wideband probes, fixtures, and sockets for high speed IC testing and interconnects

We introduce a new Periodic micro coaxial transmission line (PMTL) that is capable of sustaining a TEM propagation mode up to THz band. The PMTL can be manufactured using the current photolithographic processes. This transmission line can be embedded in microscopic layers that allow many new applications. We use the PMTL to develop a wideband highly scalable connector that is then used in a Probe that can be used for connecting to microscopic scale Integrated Circuits with picoseconds High Speed Digital and near THz Analogue performance in various stages of development from R&D to production testing. These probes, in one embodiment, provide a thin pen-like vertical probe tip that matches the die pad pattern precisely that can be as agile as a high speed plotter pen, connecting on the fly to any die pattern on a wafer. This approach allows the most valuable part of the test, namely the wafer to remain stationary and safe, and the least costly part of the test, namely the probe to take most of the wear and tear. We further use the embedded PMTL to develop a modular, scaleable and fully automated Universal Test Fixture for testing chips in various stages of development mainly for digital IC chips that can be utilized in production lines with pick and place of chips on tape to test every chip before insertion into circuits. One embodiment includes a low profile wideband Signal Launcher and an alligator type RF Clip that can be used at the edge of PCB's directly for validation broads. The Signal Launcher is used to develop a new versatile Flush Top Test Fixtures for individual device testing in various stages of development from die, to packaged, to Module, to Circuit Boards. The PMTL can also provide Confined Field Interconnects (CFI) between various elements on semiconductor wafers to reduce parasitic and radiation losses and practically eliminating cross talk, thus, increasing the speed of digital IC's. The PMTL is also used to develop a Universal Test Socket, and a Hand Probe with performance up to 220 GHz.

Method and apparatus for rapid prototyping using computer-printer aided to object realization

This invention applies a new computer and printer integrated technology to aid forming physical objects rapidly, and the method and apparatus are disclosed to satisfy the market requirements for a quick, reliable, safe, and inexpensive operation. The invention coverts a virtual object stored in the storage device of computer through software that slices the virtual object into many layers. The cross-section of the first layer is sent to a printer or a plotter, and the contour domain is printed or plotted by the printer or plotter. The fluid (not limited to binder) in the printer head is coated onto a layer of uniform distributed porous material which allows the powder and fluid to combine with each other; however, the combining process can be either a natural or an artificial process to enhance the binding force between the fluid and powder. After the first layer is finished, the second layer of powder is uniformly distributed on the first layer, and the contour printing process is repeated. As the printing process is repeated until all slicing layers of the model are finished, the object is stacked layer by layer sequentially. The physical object can be obtained after all the unglued powders are removed. The above-mentioned printing process not only produces monochrome objects, but also produces color objects. The machine includes components of a printer or plotter and its interface card, and x-z axis traversal driven mechanism. The operation platforms include a material supply chamber, a constructing chamber at which powder material is combined with solution, and a recycling hole. A slicing algorithm control software is used to calculate the cross-sectional contour, and the manufacture process is controlled by software and hardware interfaces.
