Digital devices based on complementary junction field effect transistors
This review describes the technique of logic gates design based on complementary junction field effect transistors (CJFET). Lambda-diode, circuit of two n- and p- JFET, allows to build micro power and radiation hardened digital IC that has remarkable resistance to high temperature and radiation.
Java implementation of hierarchical state machine
The note describes implementation of hierarchical state machine (HSM) in Java. A HSM is a wonderful software design template; this approach helps to create robust and flexible code especially for embedded systems.
Dining Philosopher problem: Java implementation of Active Object.
Implementation of Active Object's Quantum Framework from M.Samek book "Practical Statecharts in C/C++" is easy as pie in Java. It just don't need in Java at all, because Java has a lot of native features and libraries that can supply the all you need for Active Objects. Here is a Java implementation of DPP that prove it.
Remote services in OSGi Framework using RMI connection.
The project goal is a creating a tool (set of bundles) that allows OSGi bundles to watch and access a services running on remote OSGi framework by means of Java Remote Method Invocation (RMI). Tested with such OSGi implementations as KnopFlerFish, Equinox(Eclipse) and Oscar.
Active Object real-time OS
AO-RTOS is a pure object-oriented small footprint real-time operating system for embedded devices. The project is using Active Object (AO) and hierarchical state machine (HSM) design templates as implementation base.
