The Nucleus®I2C software from Mentor Graphics Corp. (Wilsonville, OR) is now available for developing appli cations needing access to on-board peripherals connect ed via the I2C bus. Demand is increasing for using the low-cost I2C bus to connect peripherals, such as liquid crystal...

CMX Systems (Jacksonville, FL) announced the availability of CMX-RTX™ and CMX-Tiny+™ RTOS for Luminary Micro's Stellaris (Austin, TX) microcontrollers based on the ARM® Cortex-M3 microcontroller core.

Release v8.3 of ObjectAda Real-Time RAVEN environment for PowerPC targets from Aonix® (San Diego, CA) provides RAVEN developers with a choice between the traditional Aonix IDE for development and the AonixADT™ Eclipse IDE. AonixADT incorporates Ada-project awareness, an Ada-language sensitive...

A paper discusses the continuing work of the Mobile Exploration System Project, which has been performing studies toward the design of hybrid communication networks for future exploratory missions to remote planets. A typical network could include stationary radio transceivers on a...

Small, universal mobile receivers are needed that are capable of receiving mobile satellite television signals. These receivers should be similar to those installed and used by satellite radio. The receivers will convert the signal from a satellite to a mounted or OEM satellite, thus delivering cable television to mobile...

Engineers at Massachusetts Institute of Technology (MIT) have devised new analog circuits that will not drain power or create bottlenecks like previous models. The new class of analog circuits eliminates operational amplifiers while maintaining virtually all benefits of operational-amplifier-based circuits. The MIT circuits feature...

A prototype wireless acoustic measurement system (WAMS) is one of two main subsystems of the Acoustic Prediction/ Measurement Tool, which comprises software, acoustic instrumentation, and electronic hardware combined to afford integrated capabilities for predicting and measuring noise emitted by rocket and jet...

The L-3 Communications Model 999H traveling-wave tube (TWT) has been demonstrated to generate an output power of 144 W at 60-percent overall efficiency in continuous-wave operation over the frequency band from 31.8 to 32.3 GHz. The best TWT heretofore commercially available for operation...

The cryo-hydro integrated robotic penetrator system (CHIRPS) is a partially developed instrumentation system that includes a probe designed to deeply penetrate the Europan ice sheet in a search for signs of life. The CHIRPS could also be used on Earth for similar exploration of the polar ice caps —...

A special-purpose computer code for a deformable-mirror adaptive-optics control system transmits pixel-registered control from (1) a personal computer running software that generates the control data to (2) a circuit board with 128 digital-to-analog converters (DACs) that generate voltages to drive the...

A proposed video guidance sensor (VGS) would be based mostly on the hardware and software of a prior Advanced VGS (AVGS), with some additions to enable it to function as a time-of-flight rangefinder (in contradistinction to a triangulation or image-processing rangefinder). It would typically be...
