(MIT News: Cambridge, MA) -- MIT researchers have devised a technique that reverse engineers complex 3D computer-aided design (CAD) models, making them far easier for users to customize for manufacturing and 3D printing applications.

Nearly all commercial products start as a CAD file, a 2D or 3D model with the product’s design specifications. One method that’s widely used to represent today’s 3D models is constructive solid geometry (CSG), a technique where numerous basic shapes, or “primitives,” with a few adjustable parameters can be assembled in various ways to form a single object. When finalized, the compiled digital object is converted to a mesh of 3D triangles that defines the object’s shape. These meshes are used as input for many applications, including 3D printing and virtual simulation.

Customizing that mesh, however, is no easy task. For example, adjusting the radius in one portion of the object requires individually tweaking the vertices and edges of each affected triangle. With complex models comprising thousands of triangles, customization becomes daunting and time consuming. Traditional techniques to convert triangle meshes back into shapes don’t scale well to complex models or work accurately on low-resolution, noisy files.

(NewTek: Pennsauken, NJ) -- NewTek Sensor Solutions introduces the MBB Series of ultra-precision dimensional gaging probes engineered for highly accurate and repeatable measurement of dimensional parameters in a variety of quality control, industrial metrology, and inspection equipment applications.

Offering excellent linearity, great precision, and infinite resolution, these spring-loaded AC LVDTs (linear variable differential transformers) are ideal for use in roundness measurements, automotive testing, metal component gaging, and materials testing.

The MBB Series gaging LVDT probes feature a stainless-steel probe assembly and 8 mm diameter housing protected to IP-65. High-precision linear ball bearings provide for smooth probe movement with excellent repeatability and without stiction. Incorporating a linear ball bearing assembly fitted to a nonrotating probe shaft, the MBB Series gaging probes produce an output voltage linearly proportional to the probe’s shaft position with minimal radial play. The use of an AC-operated LVDT for probe-shaft displacement reduces errors due to friction, resulting in a highly precise measurement of the position of a target surface.

(FDA: Silver Spring, MD) -- The U.S. Food and Drug Administration has published an Electronic User Guide for its Accredited Third-Party Certification Program Portal.

In this voluntary program, established by the FDA Food Safety Modernization Act, the agency recognizes “accreditation bodies” that may accredit third-party “certification bodies.” The certification bodies will be able to conduct food safety audits and issue certifications for food facilities, for both human and animal foods, and the foods they produce.

The user guide is designed to help entities apply for recognition as accreditation bodies through the portal. The user guide will also help recognized accreditation bodies manage their accounts, including profiles of certification bodies they have accredited, in the portal.

(Marposs: Auburn Hills, MI) -- Marposs has announced the availability of its new Duo premium compact electronic display unit. Similar in size to a smart phone, Duo is extremely small and powerful, featuring a 4.3 in. touchscreen unit for display and storage of measuring data acquired through one or two sensors. Designed in response to customer needs, it is a “something in-between” display unit that provides premium features at an affordable price.

Duo is well-suited for simple manual applications when only a few measurements are needed on the shop floor at any given time. Featuring two sensor input channels, it can simultaneously display two measurements at once in either analog of digital. The system is portable, easy to configure, and provides clear visualization of measurement status.

Duo is designed to work with Marposs LVDT/HVT manual gauges, such as bore gauges M1 and M1 Star, snap gauges M3 Star, ring gauges M4 and M4 Star, and Red Crown/Red Crown2 displacement sensors with a measuring range up to ±5 mm. Data collected can be exported through the USB port or the optional Fieldbus port.

(Wiley: Hoboken, NJ) -- The book, Unlocking Creativity: How to Solve Any Problem and Make the Best Decisions (Wiley, 2019), is an exploration of the creative process and how organizations can clear the way for innovation.

In many organizations, creative individuals face stubborn resistance to new ideas. Managers and executives oftentimes reject innovation and unconventional approaches due to misplaced allegiance to the status quo. Questioning established practices or challenging prevailing sentiments is frequently met with stiff resistance. In this climate of stifled creativity and inflexible adherence to conventional wisdom, potentially game-changing ideas are dismissed outright. Senior leaders claim to value creativity, yet often lack the knowledge to provide a creative framework. Unlocking Creativity offers effective methods and real-world examples of how the most successful organizations create cultures of innovation and experimentation.

(NSF International: Ann Arbor, MI) -- Whether in daily operations or at a special event, organizations are looking for more ways to implement sustainable practices and reduce the waste they create. Recently, using our expertise in materials management and waste reduction, NSF International worked with E-Reuse Services to make the 2018 Electronics Reuse Conference (ERC) in Nashville, Tennessee, a waste-free event. To achieve this, we implemented several strategies that proved successful and found several key considerations and takeaways from the event.

Things to consider

Work closely with the venue and vendors to set expectations on waste. Determine where waste may come from during the event and ways to combat waste production. For the ERC event, we worked with kitchen staff on food preparation, identified the placement of food and waste bins throughout the event space at the hotel, and encouraged exhibitors to bring items that could easily be repurposed or that created less waste. Several exhibitors brought items like biodegradable pens and reusable mugs as alternatives to traditional items.

(ANSI: New York) -- The American National Standards Institute (ANSI) has signed an agreement to acquire full interests in the ANSI-ASQ National Accreditation Board LLC (ANAB), strengthening ANSI’s and ANAB’s abilities to provide the highest quality third-party accreditation services for diverse global markets. The transaction with the American Society for Quality (ASQ) is scheduled to close on Dec. 28, 2018. Since 2005, ANAB has been owned equally by ANSI and ASQ; the purchase will result in ANAB becoming a wholly owned subsidiary of ANSI, registered as a separate legal entity and renamed the ANSI National Accreditation Board (ANAB).

While the two brands will continue business as usual in the near term, ANSI will further bolster independence and impartiality of its accreditation programs for conformity assessment bodies by integrating them with ANAB’s portfolio of services. ANSI’s accreditation of standards developers and U.S. Technical Advisory Groups (TAGs) to international technical committees will remain separately and internally operated by ANSI.

(Wiley: Hoboken, NJ) -- Scaling a business is not for the faint of heart. It’s a mind-bending journey that causes millions of business owners around the globe to either throw in the towel or avoid risk entirely and suffer from smallness and mediocrity.

Most of these businesses fail because they are ill-prepared to face the real challenges involved in scaling. Either they don’t have the bandwidth to keep up with the sales demand or production, miss out on major opportunities due to fear, or keep making the same mistakes again and again because systems and processes aren’t in sync with the rate of growth.
