Appl. No.:

12/115074

Inventors:

Daniel Wolf - Orlando FL, US

International Classification:

H01R 11/00

US Classification:

439106, 439502

Abstract:

A dual channel XLR cable converter is disclosed. In a particular embodiment, the XLR cable converter includes first and second RCA cables terminating at first and second RCA cable connectors at one end and a XLR cable connector at the opposing end. A first signal pin terminal of the XLR cable connector is in electrical communication with the first signal wire of the first RCA cable. A second signal pin terminal of the XLR connector is in electrical communication with the second signal wire of the second RCA cable. A common ground pin terminal of the XLR cable connector is in electrical communication with the first grounding wire of the first RCA cable and a second grounding wire of the second RCA cable. Therefore, the XLR cable converter can be used for conveying single channel RCA cable signals over dual channel XLR cable.

US Classification:

246187A

Abstract:

An electrically controlled railway locomotive throttle controller including a power source connected to a central processing unit disposed on such locomotive. An encoder device is disposed on such locomotive for providing at least one electrical signal to such central processing unit. This at least one electrical signal being at least one of a signal indicative of a throttle position, a signal indicative of dynamic braking and a signal indicative of a reverser. A digital control device is disposed on such locomotive and is connected to receive a signal from such central processing unit to provide a digital control signal that controls the voltage being applied to a trainline. An analog control device is also disposed on such locomotive and is connected to receive a signal from such central processing unit to provide an analog control signal that controls a dynamic brake reference voltage being applied to such trainline.

International Classification:

B60L 1520

US Classification:

36442605

Abstract:

Method of operating an electronically controlled throttle controller between two modes of operation, including a transition between modes, includes powering up an electronics package and determining if a short term power out, a long term power out or a loss of CPU control in either short term or long term has occurred. The position of throttle, dynamic brake and reverser handles is compared with a previous mode of operation to determine current mode of operation. If it is determined that the throttle controller is in handle mode, the output signal to the trainlines is adjusted according to handle positions. Outputs of throttle, dynamic brake and reverser handles are set in the home position if an RMU command is received. A predetermined delay is imposed when outputs of the throttle, dynamic brake and reverser handles are in home position after positioning by an operator of the locomotive and before exiting a handle mode and entering an RMU mode of operation. If an RMU command is received by the throttle controller after the controller has exited from handle mode, then the output signals are adjusted to the trainlines.

US Classification:

701 19

Abstract:

In a locomotive throttle controller having a digital central processor unit and an output driver mechanism for supplying signals to trainlines which control the locomotive engine throttle setting, reverser, and dynamic braking and for sending feedback signals indicative of actual voltages applied to said trainlines back to said central processor unit, of at least one locomotive, an improvement comprises a digital interface through which external digital equipment can communicate with the central processor unit and devices for communicating via the digital interface between the external digital equipment and the central processor unit such that the external digital equipment may be used to control the at least one locomotive.

International Classification:

G06F 1100

US Classification:

371 19

Abstract:

A computer program is verified, unit by unit, by automatically instrumentating the code and generating a test driver program which executes all branches of an instrumented code unit. The code is instrumented by operating processors to standardize the code format and to insert executable tracer statements into each block of reformatted code between control statements. A pseudocode having only control statements and tables identifying valid linkages between blocks of code are generated by another processor for use by a verifier in selecting values of input variables and expected outputs for test cases which execute each block of code in the selected unit. Another processor generates the test driver program from the test cases and a software test specification identifying the test cases and expected results. The test driver program and instrumented code unit are compiled and linked to repeatively execute the instrumented code unit to implement all the test cases. Results of the test cases are printed out indicating the sequence of block linkages generated by each test case, the expected output values and the actual output values.

International Classification:

B61K 1300

US Classification:

36442401

Abstract:

A protocol is provided for bi-directional communication of control signals between a host unit and a slave unit. The protocol is particularly adapted to the control of a locomotive from a remote host computer. The protocol provides for transmission of digital signals indicative of control commands from the host computer to the slave computer, and simultaneous transmission of digital signals indicative of diagnostic information from the slave computer to the host computer. Information is transmitted in the form of data packets, and means are provided, in the receiving computer, for detecting corruption of transmission, or loss of transmission, and for providing a safe response to either of such conditions.
