A distance between the pin unit and the sensor assembly during exercise can be measure by ultrasound transmitted from the transmitter unit toward the pin unit and further reflected by the reflection surface and received by the receiver unit.

Patient monitoring finger ring sensor

A monitoring system for monitoring the health status of a patient and transmitting to a remote receiver a signal, based on measured physiological parameters. A sensor is incorporated in a finger ring or other article of apparel so as to monitor skin temperature, blood flow, blood constituent concentration, or pulse rate of the patient. The data are encoded for wireless transmission by mapping a numerical value associated with each datum to a pulse emitted after a delay of a specified duration following a fiducial time. Multiple ring bands and sensor elements may be employed for deriving three-dimensional dynamic characteristics of arteries and tissue of the finger.
