In an electronically controlled RAILWAY locomotive throttle controller system having a central processor unit and a plurality of trainlines, such trainlines carrying binary voltage signals derived from corresponding binary signals in such central processor unit, a method for transmitting, for a group of said trainlines, herein numbered as NT, the binary voltage signals back to such central processor unit for diagnostic purposes. Such method includes the steps of applying, for the group of NT trainlines, their binary voltage signals to a frequency generator which will generate a signal having a frequency characteristic of such binary voltage signals. The frequency having a different value for every possible combination of binary signals from such trainlines. Transmitting such frequency signal back to the central processor unit and processing such frequency signal, in the central processor unit, to recover NT binary signals corresponding to such binary voltage signals on the trainlines in such group of trainlines.

A method of monitoring a space to determine at least one change in state related to at least one activity includes analyzing an amount of water vapor in the air over time and relating a change in the amount of water vapor in the air over time to the at least one change in state. In a number of embodiments, the at least one change in state is related to a kitchen activity which causes a change in the amount of water vapor in the air. Changes in dew point over time may, for example, are determined. In a number of embodiments, changes in dew point over time are determined by measuring temperature and relative humidity over time and determining dew point from measured temperature and measured relative humidity. Changes in dew point over time may, for example, used to identify or distinguish the activity from a plurality of possible activities associated with the change in state. At least one of change in dew point, change in relative humidity and change in temperature over time may be used (either alone or in any combination thereof) to identify the activity associated with the change in state.

A locomotive throttle controller having a CPU and output driver stage. Such CPU generates an analog voltage based on software logic and transmits to the output driver stage a signal indicative such analog voltage. Such output driver stage receives the signal from such CPU and uses it to provide an analog output voltage signal to a trainline which monitors and/or controls dynamic braking. The improvement therewith of an apparatus, for feeding back from such output driver stage to the CPU an analog signal indicating status of such trainline, comprising a device for obtaining a first analog voltage signal from a node which supplies current to such trainline. A voltage-divider for dividing the first analog voltage signal into a lower range to obtain a second analog voltage signal. A signal generating device connected to receive the second analog voltage signal and generate a third analog voltage signal. A voltage to current converter receives such third analog voltage signal and provides a regulated electrical current signal on an output terminal thereof.

A system for monitoring wellness of a person, includes a local system in the vicinity of the person. The local system includes a plurality of sensor systems. Each of the plurality of sensor systems is associated with at least one monitored system to monitor changes in state of the monitored systems caused by activity or lack of activity of the person. The local system further includes a local data communication device in communicative connection with each of the plurality of sensor system to receive data from each of the plurality of sensor systems. The system further includes a remote system in communication with the local data communication device. The remote system includes a processing system to process data from the plurality of sensor system based upon predetermined rules. The local data communication device is programmed to transmit data to the remote system. The data transmitted to the remote system includes information on state history of the monitored systems. The data on state history may, for example, include at least a time of a change in from a first state to a second and data related to duration of the second state.

An apparatus for determining and encoding the position of a control handle on a control stand of a locomotive or other railway transit vehicle utilizing a rotational, absolute encoder rigidly mounted adjacent to the axle to which the control handle is attached for pivotal motion, wherein a drive transfer means interconnecting the control handle and/or axle with encoder has a driving ratio that will permit full partial rotation of the control handle, which is typically less than 90 degrees, to rotate the encoder axle through a significantly greater rotational angle not exceeding 360 degrees, for the purpose of making fuller use of the sensitivity and resolution range of the encoder.

Apparatus and method are presented for a solid state relay module suitable for accepting low-level digital signals from a digital computer, and for providing on/off control of heavy electrical loads. The relay and its methods are intended for electrically hostile environments such that the relay may be exposed to spurious high voltages either on its input or on its load circuit. This relay and its methods are particularly intended for use in a locomotive throttle controller. The relay accepts low-level digital signals from a central processor computer in the throttle controller, and provide high-power digital signals to the trainlines which control the engine of the locomotive.
