"It is my heart-warmed and world-embracing Christmas hope and aspiration that all of us, the high, the low, the rich, the poor, the admired, the despised, the loved, the hated, the civilized, the savage (every man and brother of us all throughout the whole earth), may eventually be gathered together in a heaven of everlasting rest and peace and bliss, except the inventor of the telephone. "
Mark Twain ; Christmas greetings, 1890

| 4383370 | Wheel alignment system and method A wheel alignment system and method for determining the thrust line of a vehicle and employing the thrust line when positioning the steerable wheels of the vehicle to a plane parallel to the thrust line as well as during the determination of set-back betw... | 05/17/1983 |
| 4352291 | Wheel balancing machine A wheel balancing system for measuring imbalance forces derived from rotating an unbalanced wheel employs a stable pedestal of heavy, rigid material such as concrete or steel and a balancing assembly arranged to insure that all of the imbalance forces of ... | 10/05/1982 |
| 4341119 | Data input system for dynamic balancing machine For a dynamic balancing machine the values of parameters employed to determine the weight, rim spacing and diameter of a wheel are automatically entered into the balancing machine by a single maneuver of an extensible wand. This simplicity eliminates many... | 07/27/1982 |
| 4267730 | Wheel balancing system An improved wheel balancing system employs an information entry system with selectable compensation for input of information so that the balancing procedure can be standardized notwithstanding the fact that different styles of wheels are to be balanced. M... | 05/19/1981 |
| 4250555 | Self-calibrating data collection system for dynamic wheel balancing machine An information sensing system as used in sensing unbalanced forces acting upon a rotating wheel being balanced is characterized by means for generating a correction factor associated with each wheel balancing operation and determined by feeding a known si... | 02/10/1981 |
| 4236315 | Sensor assembly for wheel alignment system In a system for aligning a wheel employing means for generating electrical signals indicative of camber, toe and the rotational position of the wheel when the camber and toe readings are sensed employs an improved sensor assembly for generating the toe re... | 12/02/1980 |
| 4204333 | System and method for calibrating wheel alignment system sensors A system and method for calibrating a wheel alignment system to provide a compensating offset with respect to error from sensor devices involved therein.... | 05/27/1980 |
| 4174760 | Scale construction A scale construction comprises a pair of spaced substantially rigid plates offset with respect to each other and supported by means of flexure members extending therebetween. A strain gauge is carried between the plates. In one embodiment a flexure member... | 11/20/1979 |
| 4155255 | Read-out system for wheel balancer A read-out system and method for a wheel balancing machine employs means for determining the minimum angular displacement between a "balance point" on the wheel and a predetermined reference for a stationary portion of the machine using a first scale of d... | 05/22/1979 |
