The Reality of Application Security: Scare Tactics or Genuine Threat?

Guardians of application security have perhaps become slightly immune to the fearful messages of cybersecurity vendors. The combination of ‘Big Data’ with an exponentially growing Internet of Things (IoT) would seem to provide the perfect storm conditions for the exploitation of vulnerable code streams. Read this whitepaper about the reality of AppSec to discover what are the real risks and how to mitigate them.

PTC Heater Brings Greater Control for Hand-held Medical Devices and Disposables

Point of Care diagnostics devices, whether handheld or single-use, often require a brief application of tightly controlled heat. The disposable nature of these devices requires a low-cost component capable of delivering that heat reliably and safely. Heatron's new PTC heater solution uses a polymer-based heater technology that controls heat to within ±2°C of the target temperature, and reduces unit cost by eliminating sensors and applied controls.

Introduction to Electromagnetic Compatibility

By definition, Electromagnetic Compatibility (EMC) describes the ability of a system, a piece of equipment, or some other electrical device that utilizes electromagnetic energy, to operate in its intended environment without suffering an unacceptable degradation in its performance, or negatively impacting the ability of another device to perform its intended function.

Control System Basics with Jon Titus

Writer and editor Jon Titus (often credited as the inventor of the first personal computer) explores the basic elements on a control system. Beginning with relays followed by sink versus source control, Titus also explores PNP and NPN logic, open collectors and isolation. With a personable Q&A format, this five-part guide demystifies some of the common questions and confusions surrounding control systems.

Product of the Month: March 2017

Watlow, St. Louis, MO, introduced the D4T with INTUITION® data logger with a range of field-removable I/O modules. The data logger features a 4.3” color graphical touch panel with a high-resolution graphical user interface that allows channels, alarms, inputs, and outputs to be customized with user-defined names. The unit is programmable to show information in multiple languages, and enables users to choose encrypted, .CSV, or both types of file formats for tamperproof record needs. Users can select which parameters to log, from one to 128 points simultaneously, and where to store files — inside the controller, on a connected USB memory device, or to a connected PC anywhere in the world. The system records as fast as one time per 0.1 second, or as slow as one time per hour. The system is available with 1 to 24 channels, and is compatible with temperature, altitude, humidity, AC current, and other 0-10VDC or 0-20 mA process units. It connects with a controller via Ethernet, and offers communications options including Ethernet Modbus® TCP and SCPI, and EIA-232/485 Modbus® RTU.

MRAM Alternative Uses Less Energy than Conventional Chip

Purely electrical memory chips commonly used today are volatile and their state must be continuously refreshed, which requires a lot of energy. An alternative to these electrical memory chips is magnetic random access memory (MRAM), which saves data magnetically and does not require constant refreshing. They do, however, require relatively large electrical currents to write the data to memory, which reduces reliability.

Reconfigurable Chaos-Based Microchips

Researchers at North Carolina State University have developed nonlinear chaos-based integrated circuits that enable computer chips to perform multiple functions with fewer transistors. These integrated circuits can be manufactured with off-the-shelf fabrication processes, and could lead to novel computer architectures that do more with less circuitry and fewer transistors.

Supercomputer Cooling System Uses Refrigerant to Replace Water

Sandia National Laboratories researchers designed a cooling system for supercomputer centers that is expected to save four to five million gallons of water annually in New Mexico if installed at Sandia's computing center, and hundreds of millions of gallons nationally if the method is widely adopted. It is being tested at the National Renewable Energy Laboratory (NREL), which expects to save a million gallons annually. The system, built by Johnson Controls and called the Thermosyphon Cooler Hybrid System, cools like a refrigerator without the expense and energy needs of a compressor.

Computer Chips Calculate and Store in an Integrated Unit

Researchers at the University of Wisconsin-Madison created computer chips that can be configured to perform complex calculations and store massive amounts of information within the same integrated unit, and communicate efficiently with other chips. Called “liquid silicon” — liquid for software and silicon for hardware — the technology has uses in data-intensive applications such as facial or voice recognition, natural language processing, and graph analytics.
