Title: Method and system for ensuring that a train operator remains alert during operation of the train
Inventor: HICKENLOOPER HARRISON
IPC: B61L15/00
Filed: 2004-09-29
Abstract: A train control system requires a train operator to enter signal aspect information at each wayside signal position on a railroad and stops the trai n if the operator fails to enter aspect information without communicating with the wayside signal device to verify that the information entered by the operator is correct. In some embodiments, the signal aspect information is entered by pressing a button corresponding to the signal aspect information, and the location and/or arrangement of the buttons changes. Alternatively, t he operator must repeat a varying sequence (such as a series of button pushes) in conjunction with and/or in addition to entering signal aspect information.</ SDOAB>

Title: Methods and system for determining fuel consumption and fuel efficiency in vehicles
Inventor: PEPPER GARY THOMAS
IPC: B60W40/12
Filed: 2006-03-31
Abstract: A method of determining fuel consumption in a vehicle through the OBDII bus is described.

For MAP based method, an independent determining of Volumetric Efficiency of a vehicle's engine is also provided. The method is further enhanced by providing various sensing patterns for various sensor data, which depend on the rate of change of the respective data.
Patent CA-2541945-A1 (CA)
Inventor: BROWN FRED A
IPC: F23L17/00
Filed: 2004-08-23
Abstract: Apparatus and method for maintaining a predetermined flow rate in a ventilation system having a motor driven blower (200). The apparatus contains a module for determining the impedance at the outlet (260) of the blower. The impedance results from the length of pipe through which the blower blows the exhaust (240) from a heating device. The impedance is determined by using a look-up table to compare the measured rotation rate (RPMs) of the motor shaft (215) to values in the look-up table. The RPMs are measured by a sensor which provides a signal to the impedance module. Once a matching value is found, the corresponding impedance is obtained from the look-up table. The impedance is then passed to a module for setting the motor speed, which module adjusts the speed of the motor based on the impedance to maintain a constant flow rate.

Title: Method and computer program product for monitoring integrity of a railroad train
Inventor: STULL CRAIG
IPC: B61L25/02
Filed: 2006-06-15
Abstract: A method and computer program product are provided for monitoring integrity of a railroad train (10) and determining passage of the train relative to a plurality of virtual blocks defined by wireless transmissions along a section of track (54) over which the train travels. The virtual blocks provide safeguards for the travel of the train relative to other trains on the section of the track (55) when there is a shared use of the section of track. In aspects thereof, the method allows collecting data useful for evaluating conditions that may affect train integrity from at least one sensing device (14) at a end of train location. The method further allows collecting data at a head-of-train location, with the data collected at the head-of-train corresponding to the type of data collected at the end-of train location. The data collected at the end-of-train and at the head-of train location is processed (42) to determine whether the entire train has cleared a respective one of the virtual blocks. In the event this determination is unable to reach a clearance for the respective block, a cautionary status is associated with the virtual block. The cautionary status for the virtual block is automatically communicated to an offboard system, which is responsible for managing shared use of the track by other trains.

Abstract: 'NMB1870' is a known surface protein in Neisseria meningitidis expressed across all serogroups. It has three distinct families. Serum raised against a given family is bactericidal within the same family, but is not active against strains which express one of the other two families i.e. intra-family but not inter-family cross-protection. The inventors have found that NMB1870 can be divided into domains, and that not all domains are required for antigenicity.  Antigenic domains can be taken from each of the three NMB1870 families and expressed as a single polypeptide chain. The inventors have also found that NMB1870 exposes some of its epitopes in surface loops situated between alpha helices, and that substitution of loop epitopes from one family into the loop position in another family allows chimeric NMB1870 to be produced with multi-family antigenicity. Thus chimeric NMB1870 proteins are provided that comprise portions of NMB1870 from different families.
