Self-locating sensor mounting apparatus
First Claim
1. A self-locating mounting apparatus in the form of automatically adjustable headgear for accurately positioning objects against a head of a subject, the mounting apparatus comprising:
- a central mount including a plurality of inelastic elements extending therefrom, the central mount being adapted to rest on the top of a subject'"'"'s head;
an circumferential band adapted to extend around a subject'"'"'s head, the circumferential band including an adjustment mechanism;
a plurality of side elements interconnecting the central mount and the circumferential band;
a plurality of sliding joints interposed between the central mount and the circumferential band, with the plurality of sliding joints permitting extension and retraction of the central mount relative to the circumferential band;
a plurality of mounting units attached to the plurality of inelastic elements of the central mount with the plurality of inelastic elements resisting rotation of the plurality of mounting units, wherein each of the plurality of mounting units is adapted to retain an object for positioning against a subject'"'"'s head; and
at least one biasing element providing a force biasing the plurality of mounting units against a subject'"'"'s head.

Abstract
A self-locating mounting apparatus for holding objects such as sensors at specific positions on a subject'"'"'s head includes a central mount constituted by a plurality of inextensible elements adapted to fit over the top of a subject'"'"'s head. In addition, the mounting apparatus includes an adjustable circumferential band adapted to circle the subject'"'"'s head and connect the central mount to inextensible side elements via sliding joints. A plurality of biasing elements provide a force for biasing sensor mounting units on the mounting apparatus against a subject'"'"'s head, allowing for long-term sensing while minimizing interference forces on the mounting units. Advantageously, the mounting apparatus holds sensors within approximately 5 mm of their desired measurement positions over a range of subject head sizes.
