The present invention relates to a biofeedback device for providing a wearer with instantaneous and continuous information about their posture. The device comprises a sensor unit affixed to the wearer, an attachment element affixed to the wearer, an elastic cord extending between the sensor unit and the attachment element, and movement of the elastic cord due to incorrect posture actuating an indicating device. The biofeedback device further comprises a power pack separate from the sensor unit.

Biofeedback device

A probe is constructed for placement in the hot turbine section of a gas turbine engine. A housing containing two electrodes extends through the turbine shroud into the tip clearance area of the turbine rotor. A voltage impressed across the electrodes will generate an electric field in the vicinity of the turbine blades which will be distorted as the blades pass, thereby generating a charge pulse at the output of the probe. The electrode conductors are imbedded in pins which are retained by insulating rings brazed in place. The electrodes extend slightly outward from the surrounding insulating surfaces to create an air gap around each electrode. This air gap provides additional insulation and prevents contamination.
