US Patent:

57869987, Jul 28, 1998

Filed:

May 22, 1995

Appl. No.:

8/445528

Inventors:

Michael J. Neeson - Omaha NE
Edward L. Furman - Omaha NE

Assignee:

Automated Monitoring and Control International, Inc. - Omaha NE

International Classification:

H04B 100
G01S 700

US Classification:

36442401

Abstract:

An apparatus for tracking reporting and recording equipment inventory on a locomotive equipped with a mobile communications package (MCP) operatively connected to on-board intelligent devices and operative to transmit and receive information to and from at least one remote base communications unit, the intelligent devices operatively connected in a local communication network, the apparatus including a processing device operative to broadcast a Query for Health Report to on-board intelligent devices and receive Health Reports Messages from on-board intelligent devices, wherein the Query for Health Report is a request for equipment identification information and the Health Report Messages are the requested equipment identification information. A database in information transmission connection with the processing device is operative to receive and store equipment identification information. A polling device periodically initiates Queries for Health Reports to the on-board intelligent devices, and the updated Health Reports are stored in a temporary information storage database.

International Classification:

G05F 500

US Classification:

323303

Abstract:

An active power supply ripple filter with low noise and low power dissipation characteristics, which tracks the voltage of the power source with low voltage drop and high current capability. The circuit consists of a control transistor connected between one terminal of a power source and one terminal of a load, a reference circuit which tracks the supply voltage, a low pass filter which filters the reference voltage and an amplifier for driving the control transistor in response to the filtered reference voltage and a feedback voltage from the load. The circuit minimizes the voltage drop across the control transistor as well as minimizing the capacitance values required for the filter capacitors.
