Designing an autonomous underwater vehicle requires the integration of a myriad of circuits and sensors. In designing a passive acoustic array, different synchronous serial protocols are used to connect to the various components. A form of Serial Peripheral Interface (SPI) is used to connect the Analog to Digital Converters (ADCs). The battery monitoring chips return data over SMBus which is built upon the Inter Integrated Circuit (I2C) bus. The ADC used by the depth sensor communicates over SPI. MORE [pdf]
Embedded analytics technology unites embedded systems and the human senses to enable systems to analyze information and make intelligent decisions. Although embedded analytics technology appeals to a wide range of industries, there is a set of technical characteristics that most embedded analytics applications share. MORE [pdf]
With its standardized approach to a sensor interface for the Windows 8 operating system (OS), Microsoft has provided designers the means to quickly and easily develop smarter, more accurate portable devices. However, utilizing the full capability of the interface standard, especially for more complex processes such as high-level sensor fusion, still poses significant challenges. Read More [pdf]
In continuing with my computer hardware theme, I have chosen to discuss how to pick out a motherboard based on a pre-determined processor and what electrical components make the difference in this selection. Now that you picked your processor based on operating frequency, number of cores, and cache size; we will be able to determine the right motherboard to choose to optimize performance. Read More
Standardized processor modules promise their users that they will be able to change over from one manufacturer to the next. But the devil is in the details--no module can supply signals to the outside world that are not processed by the CPU. As TQ points out, what is important here is to differentiate clearly between mere marketing and technical facts.
