Claim Text:
1. A device, comprising: a vibration sensor configured to sense blood flow in a lumen of a person; a cuff coupled to the vibration sensor and configured to contact a limb of the person; a mechanical cuff tensioner coupled to the cuff, the mechanical cuff tensioner configured to adjust a compressive force of the cuff on the lumen; a tension sensor operably coupled to the mechanical cuff tensioner, the tension sensor configured to measure a first tension value of the cuff during a first sense by the vibration sensor and to measure a second tension value of the cuff during a second sense by the vibration sensor; a recorder mechanism configured to record the first tension value, a first measurement by the vibration sensor, the second tension value, and a second measurement by the vibration sensor; and an energy-recovery mechanism configured to recover energy from activation of the mechanical cuff tensioner to reduce the compressive force of the cuff on the lumen.
