One of the most anticipated airplanes, Boeing’s 777 Dreamliner incorporates a two-pilot flight deck with a five-screen electronic flight information system. If you’ve ever looked in the cockpit of a commercial airliner, you have seen the bewildering array of screens, dials, and indicators used to control the airplane. The Dreamliner flight screens replace a large number of indicators, and serve to reduce the amount of information the pilots need to deal with at one time. To b...Read More
Although the resulting product was decried by many converts to the open source movement, the developers successfully asserted their right under the GPL to keep portions of the code proprietary. But it also prompted multiple authors to fork new code bases aimed at satisfying a wide range of requirements. Most retail wireless routers are based on Systems-on-Chip (SoC) that incorporate a processor, memory, and specialized peripherals. Such systems restrict the number of hardwired LAN connections, ...Read More
Outdoor advertizing signs, also called billboards, are ubiquitous in many countries. The United States has more than 500,000 billboards in place along the nation’s highways. Historically, outdoor and indoor advertising in commercial settings has been updated and maintained by sign painters and sign installers. Now improvements in electronics hardware technology and software have improved the capabilities of the traditional signage application, and added creative new opportunities in the d...Read More
Software and hardware have a “chicken and egg” relationship – one really can’t work without the other. In Steve Leibsen’s blog, he talks about getting more capacity through multi-core based systems. That’s the hardware side of the equation, now let’s look at software to make realtime industrial control function. Ethernet was born of a PhD Dissertation by Robert Metcalf in the early 1970s. Xerox PARC, center of many new computing technologies, develope...Read More
Ultrasound is one of the most widely used diagnostic tools in modern medicine. In the late 1970s ultrasound required specially trained physicians to interpret the results from technically driven analog equipment. Some research equipment featured realistic two dimensional grey scale images, but the complexity and excessive tuning requirements to keep the equipment functioning correctly restricted its use to very specialized applications. Nevertheless, the benefits in diagnostics, especially in g...Read More
Industrial and military robots come in all shapes and sizes, tethered and untethered, autonomous or human operated, and designed for many different environments. But no matter how advanced robots are today, we’re still a long way from having a humanoid robot from science fiction. Where do you start in assembling a practical military (or industrial) robot? As with any engineering task, we need a set of objectives and a mission, which in turn defines the capabilitie...Read More
Automotive entertainment has been on a steady path of improvement ever since the invention of the car radio. Originally the automotive radio was a monaural AM receiver. This was a significant advance over stationary radios that employed dry cell batteries. Like current entertainment systems, the early radio made advances through improvement in other automotive systems. Through the late 1980s many US automotive manufacturers divided in-cabin controls across dash functions and enter...Read More
The complete Digital Surveillance System relies on several key technologies: Image capture using IP-enabled video cameras Image encode, often provided by newer generations of IP enabled cameras to minimize bandwidth requirements Image decode for playback Data storage and database analysis Image and scene analysis Threat/anomaly reporting The first four requirements provide an updated technical equivalent of an analog Video Cassette Recorder. Technological advances provide smaller,...Read More
There are a number of weather reporting desktop and mobile software packages available for free or at a low cost. But this software relies on a Windows Operating System as the hosting system. The requirement for Windows gives a small number of alternatives for realtime systems. Some vendors offer realtime operating systems and hypervisors that permit guest operating systems to run concurrently with other OSes. TenAsys (1) supports their hard realtime OS, INtime RTOS, and Microsoft®...Read More
During the course of this series, we’ll make full use of the Intel Embedded Alliance Program and other IA resources. In this installment, we’ll use Intel design decision tools that aid in choosing candidate embedded processors from among Intel Architectures. The second installment will explore Compiler Alternatives and the unique VirtuaLab access to real world development hardware. Intel, Green Hills Software, and Wind River provide mainstream development tools considered. ...Read More
