Abstract: The present invention provides a method and device of measuring the retinal stray light in the eye of a subject, comprising presenting to the subject a flickering stray light from a stray light source; presenting to the subject compensation light so as to undercompensate said part of the flickering stray; presenting to the subject compensation light, the compensation light flickering with a modulation depth so as to eventually overcompensate the flickering light being imaged on the retina; and determining from the results of a sequence of comparisons using different parameter values between the resulting retinal light flickering as perceived by the subject for the undercompensated test area and the eventually overcompensated test area a stray light parameter.

Abstract: A park brake cable system including a brake actuation lever, a connector clip having a first end and a second end, and including a shear member, having a shear failure force, positioned between the first and second ends. A brake assembly, a front cable strand having a first and second ends, the first end attached to the brake actuation lever, and the second end engaging the shear member on the connector clip are also included. Further included are a rear cable strand having a first end and a second end, the first end attached to the second end of the connector clip and the second end attached to the rear brake assembly, and tensioner means are attached in a tension force transmitting relationship with the front cable strand and the rear cable strand.
