Gerald L Thomas & Pager Belt Buckle Device

Gerald L Thomas received U.S. patent #6,597,281 for a "Pager Belt Buckle Device" on July 22, 2003.

Inventor Gerald L Thomas, was born in Savannah Georgia, grew up in Maryland, and now resides in Chicago. He came up with his idea for his buckle after working in the fashion retail business for many years. Clients coming in to try on and purchase clothing were often wearing a clip-on device on their belts, pagers or cellphones that would fall to the floor or get misplaced.

Thomas thought it would be cool and more fashionable, to have these devices as a wearable technology. Thomas states, "I'm a Buckle Designer, who just wanted to get this product to market, that can be any number of wireless accessories, housed as fashion.

Patent Abstract

A pager belt buckle device for conveniently combining a belt buckle with a pager unit. The pager belt buckle device includes a belt buckle member having an upper elongate support portion and a lower elongate support portion being spaced apart and further having a housing portion integrally attached to the upper and lower elongate support portions and being disposed therebetween and being recessed along a longitudinal back side of the elongate support portions thus forming a belt receiving slot between the upper and lower elongate support portions; and also includes pin-like support members being removably connected to the upper and lower support portions and extending therebetween; and further includes a catch member hingedly mounted about a first of the pin-like support members; and further includes a pager assembly for receiving radio signals.

Dr Anthony B Will

GM engineer, Dr Anthony B Will invented a vehicle steering system with a electronic power regulation unit and patented it on April 1, 2003.

Patent Abstract: A steering system for an automotive vehicle having two front wheels and two rear wheels is provided. The steering system includes a vehicle speed sensor; means for steering the front wheels at a desired steering angle; at least one steering angle sensor for sensing the steering angle of the front wheels; an axially displaceable rear rack, linked between the rear wheels, for steering the rear wheels at a determined steering angle; a centering resilient member, extending along the length of the rear rack, having a resiliency enabling the rear rack to return the rear wheels to a neutral steering angle position; a rear transmission mechanism connected to the rear rack; an actuator connected to the rear transmission mechanism for axially displacing the rear rack via the rear transmission mechanism against the resiliency of the centering resilient member; at least one steering angle sensor for sensing the steering angle of the rear wheels; an electronic control unit for determining a steering angle for the rear wheels from electric signals received from the vehicle speed sensor, each front wheels steering angle sensor, and each rear wheels steering angle sensor and for supplying an appropriate level of electric current to the actuator to thereby electrically empower the actuator to steer the rear wheels at the determined steering angle; and an electronic power regulation unit for selectively and electrically disabling the actuator according to electric signals received from the vehicle speed sensor, the level of the electric current supplied by the electronic control unit to the actuator, and a predetermined electric current limiting function.
