Some use cases for in-vehicle Bluetooth technology are in-vehicle relatively well-known and others will become more apparent as the popularity of in-vehicle wireless infotainment grows.

The most popular in-vehicle application for Bluetooth technology today is hands-free driving. In many states, Bluetooth not only solves safety issues associated with using mobile technology while in the in-vehicle, it also fulfills government mandates calling for hands-free driving. Another popular use case for the technology is audio streaming. By leveraging Bluetooth, consumers can stream in-vehicle songs from their smartphones and play music on their speakers, allowing them to transform their smartphone into a in-vehicle stereo.

“There is a general government-focused trend to move to multifactor authentication,” SafeNet’s Moore says. “The Embedded Computer government wants to move away from password-based protection to Public Key Infrastructure (PKI) protection. Things such as SIPRNet smart cards provide two-factor authentication and meet PKI standards. There is a large U.S. government Key Management Infrastructure the embedded computer program that is focused on creating and delivering keys to government users ensuring that key rotation –The embedded computer life-cycle management – is up to date and efficient. The life of a key depends on the mission requirements. It can last from 24 hours to 6 months to a year if necessary.

Virtualization trends in commercial computing offer benefits for cost, reliability, and security, but pose a challenge for military operators who need to visualize lossless imagery in real time. 10 GbE technology enables a standard zero client solution for viewing pixel-perfect C4ISR sensor and graphics information with near zero interactive latency.

For C4ISR systems, ready access to and sharing of visual information at any operator position can increase situational awareness and mission effectiveness. Operators utilize multiple information sources including computers and camera feeds, as well as high-fidelity radar and sonar imagery. Deterministic real-time interaction with remote computers and sensors is required to shorten decision loops and enable rapid actions.A zero client represents the smallest hardware footprint available for manned positions in a distributed computing environment. Zero clients provide user access to remote computers through a networked remote desktop connection or virtual desktop infrastructure. Utilizing a 10 GbE media network for interconnecting multiple computers, sensors, and clients provides the real-time performance and image quality required for critical visualization operations. The cost of deploying a 10 GbE infrastructure is falling rapidly and 10G/40G has become the baseline for data center server interconnect. Additionally, deploying common multifunction crew-station equipment at all operator positions brings system-level cost and logistics benefits. The following discussion examines the evolution to thinner clients and the path to a real-time service-oriented architecture, in addition to looking at zero client benefits and applications.

The AFE itself performs multiple embedded functions, depending on the application. One function of the AFE is to amplify signals that are too weak for the MCU to read. The AFE circuitry employs amplifiers to provide output voltages that are hundreds or up to thousands of times larger than the voltage provided by the sensor. This is typically done with op-amps that can vary widely in cost and power based on the required characteristics. Depending on the sensor characteristics, the AFE amplifierstructure will vary. For example, if the sensor output is differential and embedded impedance, a simple differential input can be used. If, on the other hand, the sensor output is differential and high impedance, a more complicated instrumentation amplifier, with matching high-impedance inputs, may be needed.

With the smorgasbord of Open Source Software (OSS) available for developers to dine from, it’s vital they “eat right” by choosing the OSS compatible with their existing project and IP needs.

Open Source Software (OSS) offers intelligent systems designers a veritable smorgasbord of tools and technology. Spanning the entire software stack, from boot code and drivers to OSs, executives tomiddleware, and application components to development tools, OSS provides readily available alternatives to both legacy commercial software and also to in-house code developed from scratch.

But dining at the open source table is not an embedded bean feast – code gathered à la carte might not always integrate easily to make a well-formed “meal.” While literally millions of OSS projects are available on popular forges and hubs, developers must take care to choose the right technology ingredients and tidbits to fit project and intellectual property needs.
