49272586, May 22, 1990

Filed:

Nov 9, 1988

Appl. No.:

7/268793

Inventors:

Peter L. McKenna - Woodstock GA
James M. Walters - Roswell GA

International Classification:

G02C 300

US Classification:

351156

Abstract:

An eyeglass holder includes an elongated, flexible, hollow tube for containing a sunscreen or suntan product. Caps are attached to the ends of the tube for removably covering the open ends of the tube, and flexible straps are used to attach the caps to the tube and for receiving and holding earpieces of the eyeglasses whereby the eyeglasses can be suspended from the wearer's neck.

Abstract:

This invention relates to a method and apparatus for diagnosing faulty cylinders in internal combustion engines. A probe produces a signal that is representative of the instantaneous angular velocity of the engine shaft. A Percent Power Contribution (PPC) parameter is computed by substracting the square of the instantaneous angular velocity at the beginning of a cylinder period from the square of the instantaneous angular velocity at the end of that cylinder's period and dividing this difference by the square of the average engine angular velocity. A value of this PPC parameter significantly less than zero indicates a faulty cylinder. An Average Energy Percent parameter (AEP) is computed by dividing the squares of the sampled instantaneous angular velocity values summed over a cylinder period by the number of samples in that period and by the square of the average engine angular velocity. A value of this AEP parameter significantly less than one indicates the previous cylinder in the firing order is faulty. The two parameters can be used independently or in combination to diagnose continuous and transient engine faults.
