The cylindrical speaker features two high-performance drivers, a built-in bass port and digital signal processing software to extend frequency response on the high end while providing tighter low ends for deeper bass response.

Their first test in October 2007 was a success: An all-electric car plugged in at the University of Delaware and rigged with communication software responded to a signal from PJM for a sudden burst of power to help balance supply and demand on the grid.
Scientific-Atlanta and Motorola locked up the box market by controlling--in the name of antipiracy--the encoding software that scrambles a video signal at the cable company's hub and descrambles it at the home.
As chief systems architect for the company, Kenoyer knew he could combine some clever software with the latest digital signal processor chips to make the same system at a fraction of the cost.
The court's ruling has put aside, for the short run, a more potent challenge of the FCC's ability to mandate so-called software-defined devices, which use open-source software to define how a signal can be sent or received.
The company wanted to signal to consumers that software is an important part of the phone's evolution, according to a person familiar with Apple's thinking.
But Microsoft had identified others, including Sun Microsystems's Java technologies, Intel's Native Signal Processing, and multimedia playback software developed by Apple and RealNetworks.
These short-term assignments must get done fast--designing filter algorithms for digital signal processors, say, or writing software for Internet-based phone calls.
Instead, Apple said, the apparent drop-off in reception was actually the result of a software bug that caused the phone to display more signal-strength bars than it should have.

Setup proved to be simple and straightforward, though the reviewer found it difficult to gauge signal strength, as there's no external or software-based indicator.
The folks at Solid Signal and DBSTalk have had an early preview of the fall software update that will enable it, and have both posted hands-on impressions.
The software covers text and icons including audio descriptions of the battery level and network signal.

Sure the hardware must be physically capable of transmitting the signal, but what we're really talking about here is software, not hardware.

It is limited to capturing time of call, length, battery strength, signal strength: exactly the sort of things you would quite like diagnostic software to log.
Monitoring can be switched to listen to your recording signal against your backing track without incurring off-putting latency introduced by your music software.

The Joint Tactical Radio System (see graphic, p. 100), which also involves General Dynamics, Lockheed Martin and Boeing, faces enormous technical hurdles, including how to develop software that allows ground troops, ships and planes from different countries, using 32 previously incompatible signal formats, to communicate.
