Abstract: An automated fault reporting system for a train includes a controller that gathers information concerning malfunctioning wayside status devices and automatically reports the information to an appropriate party. In one embodiment, the control module uses a positioning system and a database including device locations in order to determine when the train is near a device. If no status information is received from the device as the train approaches, or the status information indicates a problem, the train is allowed to continue at a reduced speed to allow the operator to visually confirm that it is safe to proceed. If an area monitored by the device has been passed, or if the operator indicates that there is no problem, or the device fails to respond, the controller records and reports the malfunction.

Title: Queueing technique for multiple sources and multiple priorities
Inventor: CAHN ROBERT
IPC: H04L12/56
Filed: 2005-10-12
Granted: 2010-05-11
Abstract: A method of dealing equitably with traffic from multiple VPNs feeding into a single router utilizes the weighted fair queueing (WFQ) technique of the prior art in combination with a "service level" queue comprising a set of tokens defining the class of service (COS) with the next packet to be transmitted and a queue selector that functions to query each queue in a round robin fashion. The service level queue ensures that the higher priority traffic will be transmitted first, while the queue selector ensures that each VPN will receive similar service. The queue selector may be "weighted" in that if a particular VPN generates substantially more traffic than the other VPNS, that VPN will be selected more than once during a round robin cycle to transmit a packet ("weighted round robin" WFQ).

Abstract: A method is provided for identifying mail pieces which may contain a suspicious (biohazardous/chemical agents or hoax materials). The method includes the steps of (i) causing particulate material to collect in a first region of the mail piece; (ii) producing a first content profile indicative of the internal contents of the mail piece; (iii) comparing the first content profile to a predefined baseline profile for determining whether the first content profile indicates the presence of a particulate material in the first region of the mail piece; and out-sorting a mail piece in response to the indicator. To ensure that other mail piece print, or physical characteristics, are not mistakenly identified as particulate material, steps (i) - (iii) may be repeated with certain modifications. These changes are directed to causing particulate material to collect in a second region of the mail piece envelope and comparing a newly developed second content profile with the first content profile to ascertain whether the particulate material is capable of movement, i.e., from the first to the second regions. In yet another embodiment of the inventive method and system, other detection schemes are employed which combine at least two non-specific triggering mechanisms to mitigate the instances of "false positive" indications. That is, by combining at least two such detection schemes, the probability of an accurate/valid assessment is dramatically increased.
