Emerging Radar Technology: Real-Time Through-the-Wall Surveillance

Through-the-wall surveillance (TWS) technology is an emerging technology that allows the user to see through obstacles, such as concrete walls, doors and other visually-opaque materials. Though initially developed for military use, it is now being used by law-enforcement agencies as costs have become more affordable.

One Day The End User Can Open Up A Used Battery, And Use What’s Inside as Barbecue Sauce

Of course that is not something currently possible, but what b&b batteries does have are some secret recipes for their very specialised battery designs.

Handheld Instruments: Low-Cost, Rugged Solution for Field and Lab

Handheld instruments were traditionally meant for field applications, but these are now being used in the research and development sector as a complementary product to existing benchtop instruments. Before going into how to select the best handheld for a particular application, one has to understand if a handheld device is required at all.

A Free MATLAB Alternative Called Octave

In this article we are introducing GNU Octave, a smart open source tool that has all the features that enable it to be a close alternative to MATLAB.

Designing with FPGAs: FPGA-Embedded Processors (Part 5 of 5)

This article gives information on FPGA-embedded processors with particular emphasis on the Embedded Development Kit (EDK) from Xilinx. The article also presents an illustrative example of a hands-on experience with the EDK design.

Designing with FPGAs: Clock Management (Part 4 of 5)

The focus in this article is on clock management in field-programmable gate arrays (FPGAs). It talks about the digital clock manager (DCM), which is a primitive used in FPGAs from Xilinx for dealing with all aspects of clock management.

Designing with FPGAs: An RS232 UART Controller (Part 3 of 5)

The first and second parts of the article discussed the implementation of I2C master controller and LCD display using FPGAs. The focus in this part is on designing an RS232 UART controller using an FPGA for both transmission and reception of data. The basics of RS232 protocol, data transmission and VHDL code along with details are presented in the following paragraphs.

Designing with FPGAs: Interfacing an LCD (Part 2 of 5)

The first part of the series discussed the implementation of I2C controller using an FPGA. The focus in this part is interfacing FPGA with LCD. The basics of LCD operation, hardware interconnection and VHDL code along with its description are presented here.
