Abstract:
An electrical and/or electronic supply circuit, which serves to provide a first or a second, essentially constant value of a supply voltage, which supply voltage serves to operate an operating electronics. The supply circuit serves to output the first value of the supply voltage when the supply voltage is derived from a first voltage source, and the supply circuit serves to output the second value of the supply voltage when the supply voltage is derived from a second voltage source.
Abstract:
An electronic control system for model railroads incorporates a motor control unit, an electronic state generator that generates particular operating state signals responsive to multiple reset conditions. A first reset condition initiates sequencing of motor control states and a second super reset condition independently controls system initialization conditions increasing the overall number and accessibility of controller generated operating states.
Abstract:
A safety system for an electrical distribution system that insures voltage sufficient to power user devices interfaced to the distribution system is only provided when the distribution system is fully functional and not damaged. The safety system comprises the power distribution system, a power control box, and a circuit activator signal generator in electrical communication with the power distribution system. The power control box is electrically coupled to the power distribution system and is operable to generate a first signal of a first voltage and a second signal of a higher second voltage. The power control box communicates the first signal to the circuit activator signal generator. Upon receipt of the first signal, the circuit activator signal generator generates a third signal having a third voltage that is lower than the second voltage and communicates the third signal to the power control box. The power control box provides the second signal to the power distribution system upon receipt of the third signal and does not provide the second signal if the third signal is not received.
Abstract:
An electronic control system for model railroads incorporates a motor control unit, an electronic state generator that generates particular operating state signals and a remote control signal generator that multiplies the number of remote control effects that would be available from the remote control signals alone.
Abstract:
A combination DC power source and HART adapter is provided. The present device has a first output mode, which is a conventional DC electrical output, and a second output mode, which modulates the DC output signal with a superimposed AC output signal, i.e. superimposes an analog signal on the digital signal, that conforms to a HART communications protocol. In the first output mode, the device acts as a DC power source with a variable, controllable output. In the second output mode, the device acts as a HART adapter for communicating with HART-enabled electronic devices. This mode can be used to troubleshoot and run diagnostics on HART-enabled electronic devices by simulating various error conditions, such as loss of DC power supply or erratic power fluctuation, in the field. The device combines the functionality of a DC power source with a HART adapter and is suitable for both field and non-field use.

Abstract:
Electronic circuits and methods are provided for remote control of a locomotive in a model railroad layout having an interruptible DC power supply coupled to the railroad track. The locomotive motor is isolated from the track so as to allow use of polarity reversals on the track power signal for controlling remote effects in the locomotive such as sound effects. An on-board electronic state generator is provided in the locomotive for maintaining one at a time of a predetermined set of states, at least one of the states having a corresponding remote effect associated therewith. Remote control signals such as a reverse in polarity of the DC track power signal are used to clock the state generator to a desired state, thereby permitting control of a plurality of remote effects using only the traditional DC power supply interface. The locomotive motor is controlled by a motor reverse unit so that the motor direction is controllable independently of the polarity of the DC power signal applied to the track. Accordingly, both motor direction and remote effects are controllable using only the throttle and polarity reversal switch which are available in known DC model railroad power supplies.

The power supply control system using PLC includes a repeater for recognizing a remote control signal transmitted by a remote control signal transmitter and an ID number of a corresponding electronic equipment to remote control signal transmitter and an ID number of a corresponding electronic equipment to remotely turn on/off at least one of many electronic equipments, a power line signal transmitter for converting the ID number and the remote control signal into a data signal and interfacing with a power line signal of AC power to transmit the data signal, a power line signal controller having a PLC unit for isolating the data signal from the power line signal of AC power and converting the data signal into a digital signal, and a relay integrated with the controller in the electronic equipment to control a power source toward the electronic equipment by connecting/disconnecting a power source terminal to/from a load terminal by control of the controller and connected to the PLC unit.
