Wearable cardiac defibrillator receiving inputs by being deliberately tapped and methods
View Patent ↗A wearable defibrillation system includes an output device and a motion sensor. The output device emits a sound or a vibration for the patient, who responds by deliberately tapping the system. The motion sensor registers the tapping, and interprets it as a reply from the patient. The reply can be that the patient is conscious, or convey data that the patient enters by tapping the right number of times, or that the patient wants attention, and so on. Since the patient does not need direct access to the wearable defibrillation system for tapping it, he or she can wear it under their other garments, which helps preserve their dignity and privacy.

the query has a second meaning different from the first meaning if the pattern of vibrations is a second pattern different from the first pattern.
16. The medium of claim 11 , in which
an echo human-perceptible indication is further caused to be emitted for each detection signal that is interpreted to have been caused by each tapping.
17. The medium of claim 11 , in which
the communication to the third party is caused to be transmitted only if the detection signal is received within a respond interval that starts when the questioning human-perceptible indication is caused to be emitted, and
if no detection signal is received within the respond interval, the output device is caused to emit another human-perceptible indication.
18. The medium of claim 11 , in which executing the one or more programs further results in:
causing to be emitted a confirming human-perceptible indication, and
in which the communication to the third party is transmitted only if another detection signal is then received from the motion sensor.
