Study shows surge of emergency room visits since introduction of rideshare e-scooters — ScienceDaily

A Henry Ford Health System physician is sounding the alarm on the rising number of injuries caused from riding electric scooters, calling it a growing public health concern.

In a study of e-scooter injuries, Kathleen Yaremchuk, M.D., chair of the Department of Otolaryngology — Head and Neck Surgery, says a review of emergency visits in the last three years shows e-scooter injuries have increased significantly with many of them related to head and neck injuries. The study describes how the types of injuries which include concussions, fractures, contusions and abrasions, lacerations and internal organ injuries have changed since the introduction of e-scooter rideshare systems to the public in September 2017.

The study’s break down on the type of injuries shows that head and neck injuries made up nearly 28% of the total injuries. Results were also broken down by age groups and showed that from 2009 to 2017, patients who

Introduction to the fundamental technologies of power density

To better understand the fundamental technologies of high-power-density designs, in this article I’ll examine the four most important aspects of high-power-density solutions:

  • Reduced loss generation.
  • Optimal topology and control selection.
  • Effective heat removal.
  • Reducing system volume through mechanical and electrical component integration.

I’ll also demonstrate how partnering with TI, and using advanced technological capabilities and products that support these four aspects, can help improve your efforts to achieve high-power-density figures.

But first, let’s define power density and highlight some important details when comparing solutions based on their power-density figures.

What is power density?

For power-management applications, the definition of power density seems straightforward: it is the rated (or nominal) output power of the converter divided by the volume that the converter occupies as shown in Figure 1.

But even this simple definition demands a lot of clarification if you want to compare power supplies, based on their power-densities.

The output
