Helen asked in a comment (and I've recieved multiple questions verbally) about the "growth" on my mom's arm in the one picture from my previous post (the 4th picture).
The answer is: A Body Bugg. 

Here is a little blurb from their website and a link (at the end) in case you're now even more curious!
It utilizes a patented process for interpreting calorie burn called "sensor fusion" developed by BodyMedia, Inc. This process involves collecting a range of body-data using multiple physiological sensors instead of a single sensor, which is what other calorie estimation devices such as pedometers and heart rate monitors rely on. It's this multi-sensor approach that enables bodybugg™ to "see" the wearer's context (whether they are sitting, sleeping, jogging, walking, etc.) that makes bodybugg™ such a reliably accurate device for calorie expenditure estimation.
The Physiological Sensors:
- Accelerometer
- Heat Flux
- Galvanic Skin Response
- Skin Temperature
The data these 4 sensors collect, in conjunction with the wearer's specific body parameters (age, gender, height, weight) enable the most accurate estimation of energy expenditure on the market today outside of a clinical setting. Click here for details.
