As part of a digital music system that distributes and amplifies audio music files, a secure wireless network extends the range of control to anywhere inside or outside the home. Sonos' Controller accesses the Sonosnet peer-to-peer wireless mesh network to select songs, control the volume, and, in general, provide freedom from the proximity to the PC-, Mac-, or Network-attached Storage box. The Controller has other innovative features including a movement sensor that automatically turns the Controller on when it is moved and a light sensor that limits backlighting to a minimum to conserve battery power. Design engineers choose Xilinx Spartan-3 field programmable gate arrays (FPGAs) to implement advanced capabilities in digital consumer audio products for their flexibility, features, and low cost per gate. The Spartan-3 Evaluation Kit from Avnet provides an affordable prototyping environment with tested demonstration designs to accelerate the design process.

Parallax Inc. is known for developing the Basic Stamp microcontroller development board and educational accessory kits. In addition to developing a user-friendly educational platform to learn about 8-bit microcontrollers and software programming, it created a multicore 32-bit chip called the Propeller.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
