Dec 20 - DAY 4: ZigBee in Depth Part 2
Continuing Education Center 12/20/2012 216 comments The Operating Details Under each profile is a set of operating protocols for sending set data. We will look at the structure and operation of these. We will also look at how one may use the strong structure of ZigBee to build a proprietary profile, gaining from the advantages of the protocol while providing for your unique communications and control needs.
Dec 19 - DAY 3: ZigBee in Depth Part 1
Continuing Education Center 12/19/2012 225 comments Profiles one of the primary selling points for ZigBee is the guaranteed interoperability between nodes, regardless of who made the equipment. This is assured by the use of profiles that are established by the ZigBee Alliance and are independent of any one manufacturer. We will look at the established profiles and how they operate.
Dec 17 - DAY 1: Executive Overview - What is ZigBee, Anyway?
Continuing Education Center 12/17/2012 280 comments Much is being said about the ZigBee protocol and its promise for low-power and dependable mesh networking, but what does ZigBee entail and what does it mean for a company that is thinking of incorporating it? We will discuss just what the standard and protocol are about, its history, and where it is going.
Dec 6 - DAY 4: 802.15.4 Radio Design Factors
Continuing Education Center 12/6/2012 214 comments This discussion addresses factors that affect radio communications and small radio design. Range, power, and data transfer rate together with physical size, weight, and cost impact design choices. We will speak about link budget, operating frequency, and antenna considerations. The discussion reviews power requirements for typical 802.15.4 radio systems.
Dec 5 - DAY 3: 802.15.4 Radio Protocols & Topology
Continuing Education Center 12/5/2012 213 comments This discussion considers the 802.15.4 communications protocols. We address various operating protocols, taking a look at Zigbee and competing protocols. We also address 802.15.4 radio operating topologies such as star, star-mesh, mesh, and adaptive mesh approaches.
Dec 4 - DAY 2: 802.15.4 Radio Link Modulation
Continuing Education Center 12/4/2012 237 comments This discussion takes as its focus the 802.15.4 standard as it applies to radios operating at 2.4GHz. We consider 802.15.4 modulation, the concept of "chips" and direct spread spectrum modulation, data throughput, and alternate modulation techniques.
Dec 3 - DAY 1: Navigating FCC Regulations
Continuing Education Center 12/3/2012 235 comments Federal Communications Commission rules and regulations are confusing. This discussion helps you to sort out the relevant portions of FCR 47 as it applies to ISM radio for 802.15.4-style data communications. The discussion limits its focus to regulatory matters in the United States.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
