Light Guide Foils

CoActive Technologies KDM (Newton, MA) has expanded its family of light guide foils to include devices with a thickness of less than 200μm. The light guide foils are designed to evenly distribute light from side-firing LEDs, providing bright, uniform illumination of keypads for handheld electronic devices. Backlight coloring can be software-controlled through the use of multiple sets of colored or RGB LEDs, while use of multiple light guide foils provides a zoned illumination effect. Light guide foils are constructed with poly-carbonate or TPU film materials. Typical luminance is >20Cd/m2 from two LEDs at 5mA/LED.

Return on Investment of Model-Based Design: Increasing Innovation Capacity

Jon Friedman Aerospace Industry Marketing Manager The MathWorks Natick, MA Given the current economic conditions, companies must continue to deliver existing products as they develop the products of tomorrow, without increasing the engineering staff. To accomplish this paradoxical challenge, innovative companies have adopted Model-Based Design over traditional development methods.

Electric Actuators Deliver Energy Efficient, Low Maintenance Solutions

Machine designers and end users find themselves balancing sometimes opposing priorities such as improving energy efficiency while minimizing adverse impact on the environment, at the same time ensuring performance (e.g., precision, reliability) is not compromised. A key trend towards meeting the challenges has been to shift from hydraulic actuation towards electric actuation, especially in applications characterized by high degree of responsiveness, space constraints, high uptime/low maintenance, low energy consumption, and minimal environmental impact.

Designing Electro-Optical Sensors Using Collaborative Systems Engineering Technology

About 25% of space-borne electro-optical (EO) sensor programs in both the civil and National Security Space (NSS) communities have experienced reduced on-orbit reliability, as well as cost and schedule overruns of 100% or more1-3. Many of these EO sensor program over-runs can be largely attributed to delays, errors, and inadequate communication that occur at the many handoff points between team members and contractors in the current design process. This leads to the late discovery of technical problems, making them more expensive and time-consuming to fix.
