Andrew Morris designed a circuit that could detect a stroke victim's groan and convert the sound into a signal so caregivers would know when help was needed. Here is the receiver unit.

Nice work, Andrew. It seems feature rich without being too complicated to use. I like the wireless transmission between detector and receiver, and the flashing indicator to alert when mute is on, and the confirmation the patient gets letting him/her know the call is sent.  The mute feature could be helpful when the patient has visitors in the room.

I wonder if any readers know of specific fail-safe features that would be required for nursing homes such as mic connections, power supplies, etc.

I sent the groan detector system to the lady that I built it for and she is thrilled with it. Her husband especially likes that the transmitter beeps when it's triggered, which tells him that someone will be coming to help him.

The beauty of this design is that it does not have to be tuned to the voice of any particular patient. It can be mass-produced or passed along from one patient to another. In a nursing home, you could have multiple transmitters and one central receiver, which would display the source of the signal, telling the nurse which patient required attention.

Also, the hardware is very simple, and the software could easily be rewritten in whatever language, or for whatever microcontroller the builder is comfortable with.
