Known for its precision linear guides and self-lubricating bearings and slides, Pacific Bearing tells Design News that its design engineers are working to develop a fully integrated actuator consisting of a linear motor, slide, and encoder. Planned rollout date is September 2003. Calling the new product a "linear slide for the masses," CEO Bob Schroeder says that the company plans to price it at around $2K or less, saying that comparable systems cost on the order of $7 to $8K. Though Schroeder would not reveal exact performance specs of the actuator, he says that its repeatability will be on the order of a couple of microns and that the maximum stroke length will be 1.5m. Force and acceleration will depend on the type of magnets employed, though in order to keep costs down, engineers are likely to employ less expensive magnets, which generate lower forces. However, engineers plan to use a tubular linear motor, a particular motor design that exploits the total available magnetic flux to generate thrust. The thrust block also contains iron to boost the force output. Target markets include packaging and automation, and any high-volume application involving tough or extreme environmental conditions.
United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
The new small-form-factor EZ-BLE PRoC (Programmable Radio on Chip) module is a derivative of the existing PRoC BLE Programmable Radio-on-Chip solution. The EZ-BLE PRoC module integrates the programmability and ARM Cortex-M0 core of the PRoC BLE, two crystals, an onboard chip antenna, a metal shield, and passive components.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
