Abstract: A protective garment is provided and includes a jacket having various releasably mounted protective components. The jacket includes a protective collar of ballistic resistant fabric for protecting the neck of a wearer and has front and rear portions which are releasably connected together at opposed side portions of the collar so that the front and rear portions can fold down when not in use. A protective plate is releasably fastened to the front of the jacket and the fastening mechanism allows the plate to be held in a number of different vertical positions. The jacket also includes a rear pocket for housing a rear protective plate. The sleeves of the jacket include a sleeve extension which is slideably mounted to the main sleeve to vary its effective length.

Abstract: A method for creating a frame of reference of a leg of a subject for subsequent 3-D kinematic analysis of the leg with non-invasive trackable references secured to the femur and the tibia of the leg. The method comprises the steps of: i) obtaining tibial and femoral axes with respect to the trackable references by tracking points and motions of the leg; ii) registering a known posture of the subject with respect to the trackable references; iii) obtaining a desired posture of the subject with respect to the trackable references as a function of the known posture by tracking a predetermined motion of the leg; and iv) setting a frame of reference to said tibial and femoral axes of the leg in the desired posture of the subject with respect to the trackable references.

Abstract: A harness for attachment about a knee femur and comprised of a rigid and non-flexible frame support two resiliently mounted clamping means and sensors is described for the non-invasive measurement of knee motion and its analysis in 3-D is described. The clamping means elements are urged under pressure outwardly for application against a skin outer surface at predetermined medial and lateral sites relative to a femur. A non-resilient adjustable stabilizing element is connected to the rigid frame and disposed at a predetermined location with respect to the medial clamping element in spaced relationship therewith and adjustable for clamping contact on a skin outer surface and in alignment with the center of a medial condyle of the femur whereby to stabilize the rigid frame about a knee. An attachment rod is secured to the harness and has straps for securing the rod above the knee.
