Introduction
The myActive Alert is a personal emergency response pendant manufactured by
Mytrex, Inc. that features patented and clinically validated automatic fall detection
algorithms developed by BioSensics LLC. Additional key features and benefits of the
BioSensics technology include patented algorithms designed to reduce false alarms,
monitoring the number of steps taken, and notifying providers when the pendant is not
worn by the subscriber. The myActive Alert also incorporates a water resistant HELP
button to request help at the press of a button.
The myActive Alert may be operated in one of two modes: Basic and Enhanced. In
either mode the device may be programmed to transmit a periodic supervisory or
heartbeat signal to the Mytrex personal emergency response system (PERS); such as
an MXD or MXD3G. This transmission enables the base unit to monitor the radio link,
battery condition and activity level of the user.
Detecting a Fall
When the algorithms determine a fall may have occurred, the LED begins to flash
slowly. A few seconds later the LED will flash quicker. Within a few seconds the LED
will turn on steady and a FALL ALERT signal is transmitted to the PERS. A red LED
indicates low battery and green indicates a good battery. During the FALL ALERT
signal transmission, the LED will always illuminate steady for approximately two
seconds.
Note: Due to the many types of falls that can occur, the user should
always press the HELP button whenever help is needed and not rely solely upon
the determination of the fall detection algorithms. See
“Other Notices”.
Sending a HELP ALERT Signal
To send a HELP ALERT signal to the PERS, press and release the HELP button on the
face of the myActive Alert. The signal for help is transmitted as soon as the button is
pressed and will continue to transmit for an additional two seconds after releasing the
HELP button. The LED will illuminate for the entire duration of the signal transmission
according to Table 1.
Clearing the FALL ALERT
When the algorithms determine a fall may have occurred, the LED begins to flash
slowly. While the LED is flashing, the algorithms continue to monitor movement.
Transmission of the FALL ALERT signal is prohibited and the LED is turned off if the
algorithms determine the user has taken three steps. Once the LED turns on steady,
the FALL ALERT signal cannot be cancelled.
Battery Monitoring
The myActive Alert periodically monitors the internal battery voltage. If the voltage is
below a certain threshold, a LOW BATTERY signal is transmitted to the PERS. Once a
low battery is reported, the myActive Alert should be replaced within two weeks.
