New product features, certification, increased performance and quicker design cycles are pressuring device manufacturers to reduce costs and still meet time-to-market requirements. Considerations like balancing increased performance and demands for lower design, manufacturing costs, freeing up engineering resources, or selecting the right OS and BSPs complicate the decision-making process. Sign up now for an innovative webinar using an on-line tool that calculates when and if you should buy or build.
The Multi-purpose PWM Wave Shaper utilizes four identical boards, each with a 74AXP1G57GM chip and a 4k7 pull-down resistor on every input. The circuit is designed using all four AXP chips that are capable of producing a signal with a 0, 25, 50, 75 or 100% duty-cycle. The system is capable of switching between the five signals through a single simple five-position switch making it capable of five inputs that each selects a different duty-cycle.
The 74AXP1G57 configurable logic is used as the basic component for the design of a Light Sensor and a Photosound device in this project. The light sensor is designed using a 74AXP1G57 configurable logic, photoresistor and capacitor, which is a system designed for luminance measurement in low voltage systems. Photosound on the other hand was designed using the combination of two light-dependent generators using Ex-NOR gates to intermodulate output waves making it possible to obtain nearly 0 Hz frequency or some beat frequency.
Power Integrations’ new LYTSwitch-2 LED drivers facilitate repeatable driver performance and reduced component count, with up to 12 watts of accurately controlled output power for bulb, tube and ballast applications. LYTSwitch-2 devices deliver constant current and constant voltage output (CC/CV), achieving CC output regulation of +/-3% in a typical design. Circuits designed with LYTSwitch-2 parts deliver long lifetimes and high reliability – in even the toughest lighting conditions.
For years, SHA-1 authentication has been used to effectively protect intellectual property from counterfeiting and illegal copying. As computer technology advances, customers need an even higher level of security. Today a new group of secure authenticators and a companion secure coprocessor implement SHA-256 authentication. This new system provides advanced physical security to deliver low-cost IP protection, clone prevention, and peripheral authentication.
The Space and Systems Development Laboratory (SSDL) develops innovative technologies for robust distributed systems, with special interest in space environments. The current satellite mission under development at the SSDL is the KatySat satellite, which provides a powerful educational outreach tool for K-12 students that can be readily expanded for future missions. To facilitate the KatySat mission, SSDL partnered with Total Phase, to provide students the tools necessary for embedded system development.
Ever since 1982, when a Pennsylvania high school student unleashed Elk Cloner -the first known microcomputer virus to spread in the wild- cybersecurity technology has been playing catch-up. Viruses, Trojan horses, worms, back doors, spoofing, and other cyber-security threats are now part of everyone’s computer vocabulary. What’s next? For all of its promise, the Internet of Things is likely to become the greatest challenge for security technology to date, defying conventional security solutions, paradigms, and tools.
Vehicles capable of autonomous operation are in the early stages of development for use on the roads. To move self-driving cars from vision to reality, auto manufacturers depend on enabling electronic technologies for sensing, sensor fusion, communications, and high-performance processing. Autonomous vehicle control systems have to be scalable to accommodate evolution as car models change and data loads increase with additional features and improved sensors. Innovations that can result in scalability include the use of distributed processing and localized sensor fusion.
