The Self-Driving Car

Since the first demonstration of a radio-controlled car in 1925, the automotive industry has been seeking to build a reliable driverless vehicle. The safety of robot-quick reflexes and predictive algorithms, combined with the convenience of effortless travel, is appealing. For those who cannot physically drive, an autonomous car allows a new level of freedom. Of the 5.5 million car crashes per year in the United States, 93 per- cent of them have a human cause as the primary factor.1 A self-driving car could reduce such accidents and, as a bonus, use its predictive driving to reduce fuel consumption and traffic congestion.

Virtual Prototyping: Visualizing the Next Generation of Products

The Department of Defense defines a virtual prototype as “A computer-based simulation of a system or subsystem with a degree of functional realism comparable to a physical prototype.” A virtual prototype is built from CAD drawings of separate assemblies that are gradually placed into the whole. Since the drawings of each subassembly are detailed and accurate, you can accurately assess their form (overall shape), fit (ease of as- sembly), and function (making sure it performs as specified). In addition to these traditional three Fs, the virtual prototype can be used for motion studies and studying interactions be- tween the machine and the humans who will use it. Once the design is complete, you can use the digital model to see whether parts interfere as you move them through their com- plete range of motion. In the past, design and analysis have been separate tasks, performed by different teams. With virtual prototyping, these functions are completely entwined.

Analog Signal Conditioning for Accurate Measurements

By Jon Titus Q: Should I put some sort of circuit between my sensor and an analog-to-digital converter? A:Yes. You probably need some signal conditioning. The explanation below goes on for a bit, but stay with it and you'll understand what you need and why you need it. Before you make any connections, get the electrical specifications for the analog-to-digital converter (ADC) and for the sensor or sensors in your system. Let's assume the data-acquisition module uses a Maxim Integrated Products MAX197 12-bit ADC. This device can accept eight differential (2-wire) inputs or 16 single-ended (1-wire) inputs. Maxim's specifications show an input impedance of 21 kohms for single-ended inputs and 16 kohms for differential inputs.

Meeting Industry Standards for Sanitation in The Food Industry

Food service equipment manufacturing and electropolishing go hand in hand. Parts said to be made of “Food Grade Stainless” typically have undergone finishing operations such as passivation or electropolishing to enhance the cleanliness and corrosion resistance. With electropolishing, you also receive the added benefits of microfinish improvement and deburring.

High Precision Multi-channel PXIe Systems Realize More Efficient Wind Tunnel Testing

Wind tunnel testing is widely used in large-scale aerodynamic design projects. Even so, the requirement for large numbers of sensors over large areas of the devices to be tested presents major challenges in data acquisition and retrieval. The article discusses use of multi-channel PXIe systems to achieve fully synchronous, high-efficiency, highly precise measurement solutions. Attributes include: PXIe technology providing effective single-system integration with multiple combinations of a wide variety of sensors PXIe platforms’ PC-based structure delivering easily deployed superior computing power along with networking capability, minimizing development time and simplifying setup

Prosthetic Hands Give Patients A New Feel For Life

The human hand is a biomechanical marvel, but our hands are easy to take for granted because we depend on them all day long. People without all or part of their hands, however, know full well the value of what is missing as they struggle to perform even simple, everyday tasks.
