Portable radio-controlled alarm. The transmitter is waterproof with a long lifetime. It sits on a plate; a plexiglas disc sits on top of it to increase the area on which to apply pressure. The user attaches the transmitter to the side of the wheelchair cushion with a Velcro strap. The assistants have a receiver, a small box with clips to be able to attach it to clothing. The alarm gives an audio signal and vibrates.
