Connecting the Unconnected: Evolving Manufacturing Connectivity, Part I - Challenges to Brownfield Development

Learn about common obstacles encountered on the road to connected manufacturing, and preview some solutions provided by ADLINK and Intel. Cisco estimates that 92% of the 64 million manufacturing machines in worldwide operation are unconnected to any network, despite remaining in full use on production lines everywhere. To prevent considerable costs being incurred, viable optimization of existing machines embodies connection to the Internet, effectively integrating them into Smart Factory systems while maximizing acquisition and analysis of operational data, all within acceptable cost constraints.

National Institute of Standards and Technology (NIST)

The National Institute of Standards and Technology (NIST) was founded in 1901, and is now part of the U.S. Department of Commerce. Based in Gaithersburg, MD, it was established to remove a major challenge to U.S. industrial competitiveness at the time — a second-rate measurement infrastructure that lagged behind the capabilities of the United Kingdom, Germany, and other economic rivals.

Decoupled Ranging and Orientation Inversions Enable Linear and Fast Long-Range Non-Line-of-Sight Positioning

New linear solutions are significantly simpler than the previous complex nonlinear solutions.

The wireless radio positioning or radiolocation problem is of great importance in society today. Existing radiolocation systems such as the Global Positioning System (GPS), Radio-Frequency Identification (RFID) systems, and Ultra Wide-Band (UWB) systems use propagating EM waves and show reduced accuracy in non-line-of-sight (NLoS) environments due to propagation losses, delays, or multi-path effects. These significantly limit their use in radiolocation applications where the line of sight to the device is blocked. Examples of these are many, and include radiolocation for a device inside a cave or building, embedded underground or in a tunnel or mine, and for underwater applications, which covers a multitude of space, military, and civilian applications. In addition to these severe limitations, existing radiolocation systems using propagating EM waves enable ranging and positioning, but cannot provide precision two-dimensional (2D) or three-dimensional (3D) orientation sensing, which is critical in many applications where the sensor's attitude is important.

Ultrasonic Transducer Delivery Tool

This tool can be used in any industry using double-walled storage tanks.

Stennis Space Center has the need to measure the inner wall thickness of cryogenic storage tanks without entering the inner tank of the double-walled vessels. It was proposed that an ultrasonic probe be inserted through access points in the outer wall of the vessel and delivered to the inner wall of the vessel, which would provide for at least a discrete set of inner wall thickness measurements where access points were available.

Nanofabricated Devices Detect Ultrasound with Light

Tiny, soft, transparent, nanofabricated devices can be integrated into a contact lens.

The Micro-ring resonator detector can determine the speed of blood flow and the oxygen metabolic rate at the back of the eye. This information could help diagnose such common and debilitating diseases as macular degeneration and diabetes. The tiny, transparent device can fit into a contact lens, and could help a range of scientific endeavors from biomedicine to geology.

Bio-Detection System is a Handheld Chemistry Lab

The device miniaturizes bench-scale analyses in a handheld, low-power device.

Devices for manipulating fluids on the microscale have been developed to store, hold, and manipulate small amounts of fluids, and have been applied to the detection of analytes in sample fluids. Manipulating fluids and performing capillary electrophoresis in microfluidic devices promises advantages of small size, high throughput, low sample volumes, and low cost.

Impedance Measurement Box

This tool provides single-point measurement of batteries.

The dependability of energy storage devices — particularly batteries — is becoming increasingly important to consumers, industry, and the military. As battery technology becomes more complex and users' expectations become more pronounced, there is a pressing need for highly accurate assessment techniques that can give state-of-health readings in conditions approaching real time.

Transducer-Actuator Systems for On-Machine Measurements and Automatic Part Alignment

These systems have applications in machine shops, and in automotive and aircraft parts and manufacturing.

When performing machine tool setup and maintenance operations, it is frequently necessary to use a position transducer to “sweep” a surface and establish its relationship to a machine. A machine operator or maintenance technician typically attaches a position indicator to one portion of a machine, and then sweeps the position transducer over the object of interest, while observing the indicator run-out. If necessary, multiple adjustments and re-checks are made to the position of the object to obtain the desired alignment condition.

Paper-Based Electrochemical Test Strip Detects Harmful Bacteria

This test could eliminate the need for more expensive follow-up tests.

Borrowing concepts from medical diagnostic devices, researchers have created a simple, inexpensive set of handheld tests that can detect the presence of many water- or food-borne pathogens. If applied in the field, such tests could greatly reduce the number of expensive follow-up tests needed to keep the food supply safe from fecal contamination.
