The PSST transmitter could probably be made small enough to hang in a necklace pendant, similar to some competitive safety monitors.

The PSST System is designed with VERY simple, inexpensive transmitters, so the purchase or rental cost would be VERY low.
Elderly people are at increased risk of injuries, illnesses and falls. If this should happen when and where they are alone, it might be a great deal of time before help arrives.

An improved, economical system would be beneficial.
The PSST System is all of this, and more!
