The idea of having a display for how many charging cycles may be left is a great idea,  but why can't they implement some type of wireless charging for back up purposes just in case of failure?

Several studies indicate that the noise generated by performing orthopaedic surgery has the potential to cause hearing loss. Noise produced by several orthopaedic surgical instruments such as saws, drills, and hammers during surgery exceeds 100 dB, especially during knee replacement procedures. Surgical protection suit may help to protect surgeon from noise-induced hearing loss.

I like the idea of a display, Greg - that would allow the user to know immediately whether or not the battery should be considered for service without any additional steps. Sounds like a good PIC project to me ;)

Yes, the data chip idea would be nice.  Ideally, the charging station would have some type of display which would show the user what percent of charging cycles are left in the battery (and warn if a battery should be replaced soon).

That's a great idea, Greg - from a reliability standpoint they could then discard the battery before it neared the end number of its specified charge cycles - in a critical application such as this that might be a good approach to ensure sufficient battery life. For example - maybe a battery that is spec'ed at 500 charge cycles you could pull it out of service at 400 charge cycles.

It would be really nice to have a data chip in the battery pack that keeps track of the number of cycles and the maximum temperature of the battery pack - that might help you be able to tell when a failure is imminent.

I can see where this technology would be extremely valuable in a military wartime setting. The medical facilities are rarely state of the art and usually dependant on generator power.

Good point about monitoring remaining run-time to avoid unexpected power-down during operation.  Is there also a feature on the charging station which monitors the number of charges each individual battery pack receives?  (monitoring charge cycle life).

Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
