Abstract

A transmitter assembly is characterized by a buckle including fasteners for holding a strap and the buckle together on an appendage of an individual independent of a transmitter. The buckle also includes latches for attaching the transmitter to the buckle after the buckle is strapped to the individual. An optical fiber running through the strap is held by the fasteners with the ends of the fiber in predetermined positions relative to the buckle. The transmitter covers the strap fasteners, rendering the fasteners inaccessible to the individual, and aligns an emitter and sensor on the transmitter housing with the ends of the optical fiber in the predetermined positions. The ends of the strap are aligned adjacent one another by the buckle, so the buckle adds little to the length of the strap, permitting length measurements without considering the buckle contribution.
