By Brian Santo for Mouser Wearable medical devices and implants are becoming more prominent in a wide range of applications such as health monitoring devices and biomedical implants, which provide continuous measurements of biomarkers and medical diagnostics. Based on growth of the elderly population and insights garnered from the pandemic, the shift to the development…
FAQ
Testing batteries for an evolving world
Battery testing enables vehicle manufacturers, owners, and researchers to make informed decisions, optimize vehicle performance, and enhance overall user experience. Demand for electric vehicles is amping up. Every one of these vehicles needs large batteries, and the industry is responding by building plants. Energy.gov forecasts that by 2030 electric vehicle battery manufacturing capacity in North…
Battery configurations (series and parallel) and their protections
A single cell is not sufficient for some devices. To achieve desired voltage, the cells are connected in series to add to the voltage of the cells. To achieve the desired capacity, the cells are connected in parallel to get high capacity by adding ampere-hour (Ah). This combination of cells is called a battery. Sometimes…
How is sensing involved in deep sea exploration?
As the recent loss of OceanGate’s Titan tourist vessel has revealed, exploring in the ocean’s depths is very risky business. To see the Titanic up close and personal, the Titan would have to travel to a depth of 3,800 m (12,467 ft), where the pressure is 382.45 bar (5,547.14 psi or 38,246.06 kPa). It turns […]
How do the seven types of V2X connectivity work?
Vehicle-to-everything (V2X) communication includes vehicle-to-network (V2N), vehicle-to-infrastructure (V2I), vehicle-to-vehicle (V2V), vehicle-to-cloud (V2C), vehicle-to-pedestrian (V2P), vehicle to device (V2D), and vehicle to grid (V2G). This FAQ begins with a review of dedicated short-range communication (DSRC) and cellular vehicle-to-everything (C-V2X) technologies for V2X communications, looks at the four V2X service types and the structure of telematics control […]
The Radio Data System: FM radio adds features to stay viable, part 4
Broadcast FM radio has extended its user-friendly capabilities through the addition of embedded, backward-compatible functionality which adds text and even graphics to the radio display. This part concludes with additional RDS details and IC implementations. Q: Where is the RDS signal in the FM-channel spectrum? Does it affect existing FM stereo broadcasts? A: One of […]
How is functional safety defined & implemented for batteries in EVs and BESS?
Li-ion batteries can store large amounts of energy, and they can support high rates of power delivery. They are the preferred energy storage technology for EVs and large battery energy storage systems (BESS). But if not properly managed, they can also present safety hazards. That makes functional safety a critical consideration when designing large Li-ion…
How does sensing help in paranormal research?
Paranormal does not usually imply a scientifically sound phenomenon. However, when science is used to verify the observation, the situation changes. This is where a variety of sensors come into play. After all, it is called extra sensory perception (ESP). In the United States, a push in the scientific community to empirically study paranormal experiences […]
What are the five levels of vehicle connectivity?
There are several efforts underway to define levels of vehicle connectivity that parallel the levels of driving automation defined by the Society of Automotive Engineers (SAE). The concept of autonomous vehicles, particularly at the higher levels of automation like self-driving cars, is still largely aspirational and a goal for some time in the future. Connectivity, […]
How does MBSE work for EV and stationary battery energy storage systems?
Model-based systems engineering (MBSE) is comprehensive. The International Council on Systems Engineering (INCOSE) defines MBSE as the “formalized application of modeling to support system requirements, design, analysis, verification, and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases.” It’s especially applicable to complex systems of systems like…
