    摘要： A retro-reflective identification tag capable of modulating an optical signal whereby to support bi-directional communication with an associated remote optical interrogation device. The tag comprises a MOEMS modulating layer over a retro-reflective substrate, giving the tag a wide angle of effective operation. The tag modulator may optionally be switched on only responsive to detection of a precursor beam from the interrogation system in order to save power. The interrogation device may make use of multiple optical wavelengths for communicating with the tag.

    摘要： An orthopedic and orthotic bipivotal hinge assembly having a hinge body and a pair of coplanar and independently-pivotal hinge arms. The proximal end portions of the hinge arms are disposed within the hinge body and have at least one set of interdigitating end plates defining an arrangement of abutment surfaces that are coplanar with each other, face generally in the same direction, and are disposed in side-by-side relation, when the arms are in first positions of adjustment (e.g., extension). In one embodiment, a single set of interdigitating plates with one such arrangement of abutment surfaces is provided; in a second embodiment two sets of interdigitating plates with two arrangements of abutment surfaces for controlling both extension and flexion are provided. Continuously variable extension and/or flexion control is achieved by an adjusting screw, or a pair of adjusting screws, carried by the hinge body.
