A personal protection device can be used to protect individuals from falls. The device can be linked to a mechanical or electrical device, which triggers deployment of the device when the individual accelerates vertically. In this manner, a falling individual's injuries such as hip fractures, upper extremity injuries, and head injuries are minimized by the mediated gradual deceleration of the wearer of the device. The device allows mobility of the individual, because it is worn in a non-deployed compact form within a wearable article of clothing or belt. The device may also be used to protect non-ambulatory individuals who sustain falls from a bed or chair.

A protective helmet includes a plurality of fluid filled bladders, impact sensors, valves, and pumps wherein the helmet absorbs energy from an impact to protect a person wearing the helmet from traumatic brain injury. The bladders expel fluid in response to a triggering event such as energy from an impact detected as a pressure spike event and/or detected as an acceleration event. A selected bladder may expel fluid to other bladders, to a reservoir, to the environment outside of the protective helmet, or combinations thereof. In embodiments where the bladders need additional fluid after an impact, one or more pumps may refill selected deflated bladders. When a bladder is underinflated, an indicator light may emit light on an outer surface of the protective helmet to warn that the bladder is not yet ready to be placed in operation to absorb another impact.

There are many inventions described herein as well as many aspects and embodiments of those inventions. A thigh compression device and technique to control, time, delay and/or prevent excessive early venous enhancement relative to arterial enhancement and thereby improve and/or enhance MRA images, including peripheral MRA images. In one embodiment, the present invention uses a curved strip of material which is longer on the superior edge and shorter along the inferior edge. When wrapped around the conical or conal-like shape of the thigh of a subject (for example, a human), the thigh compression device more uniformly conforms to and/or fits around the thigh, providing more even/uniform compression as well as reducing, minimizing and/or eliminating significant movement of the thigh compression device towards the knees of the subject. Notably, a snug fit on the thighs may also enable the thigh compression device to be inflated with less fluid (for example, air) which is faster and less cumbersome for the operator.
