"The abolishment of pain in surgery is a chimera. It is absurd to go on seeking it...knife and pain are two words in surgery that must forever be associated in the consciousness of the patient."
Dr. Alfred Velpeau, French surgeon ; 1839

A definable address is associated with the model vehicle, for example by being stored in a memory device connected to the control and evaluation device. The control and evaluation device includes or is connected to a switching network that is operable to selectably connect one of the drive devices to a regulating device in response to control signals from a central control unit. The regulating device is connected to a power supply and is operable to regulate the power supplied to the selected drive device in response to control signals from the central control unit. The control unit sends an address as part of its control signals, and the vehicle responds to the control signals if it has an address matching that sent by the control unit. Thus, a plurality of drive devices on a single vehicle can be selectively operated based on a single address unique to that vehicle. | InventorApplicationNo. 865296 filed on 05/29/1997US Classes:318/39, Work and feed motors (e.g., indexing)246/4Cab signal or train controlField of Search318/139, BATTERY-FED MOTOR SYSTEMS318/34, PLURAL, DIVERSE OR DIVERSELY CONTROLLED ELECTRIC MOTORS318/39, Work and feed motors (e.g., indexing)246/3, Central signal control246/4, Cab signal or train control246/5, Selective246/6, Train-order cab signal or train control246/7, Train telegraphy or telephony246/167R, CAB SIGNAL OR TRAIN CONTROL246/187R, Electric246/187A, Remote control246/182R, Speed-control systems246/187B, Non-mechanical control of vehicles from wayside246/191, Visual cab signals246/192R, Train mechanism246/193, Electric or magnetic246/194, Inductive246/196, Cab-circuit controller180/167, WITH MEANS FOR CONTROLLING OPERATION RESPONSIVE TO ELECTROMAGNETIC RADIATION, MAGNETIC FORCE, OR SOUND WAVES RECEIVED FROM SOURCE, OR REFLECTED FROM OBJECT OR SURFACE, LOCATED APART FROM VEHICLE446/433, Endless track vehicle446/442, Reversing446/454, Remotely controlled446/455, Via conductor adjacent to vehicle path446/456, By radio signal446/457, Including intrinsic motive power means for propulsion446/458, And eccentric weight446/459, Elastomeric (e.g., rubber band)446/460, Steering vehicle446/461, Having lock for rotary motor or transmission446/462, Having instrinsic energy-storing battery or flywheel446/463, And clutch446/464, Flat spiral or torsion spring446/465, Wheeled vehicle446/466, Wheels vertically movable relative to chassis446/467, Railroad locomotive simulation104/296, Auxiliary function on car104/295, External car control104/297, Superimposed signal on same conductor104/300, Car-carried speed regulator104/301Of multiple trains on same trackExaminersPrimary: Salata, JonathanAttorney, Agent or FirmUS Patent References4307302, Electronic control systemIssued on: 12/22/1981 Inventor: Russell4335381, Remote control of electrical devices Issued on: 06/15/1982 Inventor: Palmer4341982, Simultaneous independent control system for electric motors Issued on: 07/27/1982 Inventor: Lahti , et al.4572996, Control unit for model vehicles Issued on: 02/25/1986 Inventor: Hanschke , et al.5073750, Remote control apparatus for installation of electrical toy and circuit Issued on: 12/17/1991 Inventor: Coron5267318, Model railroad cattle car sound effects Issued on: 11/30/1993 Inventor: Severson, et al.5321344, Control circuit for model railroads Issued on: 06/14/1994 Inventor: Ott, et al.5749547Control of model vehicles on a track Issued on: 05/12/1998 Inventor: Young, et al.
