Abstract:
An exploration technique allows a router to efficiently determine capabilities and configuration of a neighbor (peer) router. In addition, the technique enables peer routers of an adjacency to negotiate a capability “outside” of a protocol, such as a routing protocol, before a routing session is established between the routers. In this context, the term “outside” of the protocol denotes that there is no field within a protocol packet (message) implementation that can be used to negotiate the capability. Moreover, the inventive technique obviates the need to manually configure a router to support a particular capability and interoperate correctly within a network of routers that both support and are unaware of the capability.
Abstract:
A method and system of controlling auto-ignition timing in an internal combustion engine cylinder in which the timing of auto-ignition in prechambers that are coupled to the cylinder is precisely controlled. The auto-ignition in the prechambers is produced by a compression stroke using pistons situated within the prechambers. Hot gas jets produced by the prechamber auto-ignitions are introduced into the charge space of the cylinder and rapidly induce a second auto-ignition of the mixture in the cylinder. By precisely controlling the timing of the auto-ignitions within the prechambers, the timing of the auto-ignition within the cylinders can, in turn, be precisely controlled.
Abstract:
A respiratory mask is provided with an eye shield having a body portion which is releasably-secured to the mask, and a shield portion which shields the eyes of the wearer. The shield portion is self-supporting on the body portion and, hence, on the mask, and includes a sheet of transparent, eye-shielding, material which can be replaced if it becomes marked or damaged. The shield portion can be pivoted forwards, relative to the mask, so that it is removed from the line of vision of the wearer without affecting the respiratory protection provided by the mask. A valve arrangement in the body portion of the eye shield can divert air from the mask into the shield portion, to remove contaminants from the region around the eyes of the wearer.
Abstract:
In an aspect, an apparatus for predicting downhole conditions is disclosed. The apparatus comprises at least a processor and a memory communicatively connected to the at least a processor. The memory containing instructions configuring the at least a processor to receive a condition datum. The memory additionally contains instructions configuring the at least a processor to produce a measured downhole condition using at least a sensor. The memory instructs the processor to convert the condition datum and the measured downhole conditions into a cleansed data format using a data conversion module. The processor is instructed by the memory to identify a flagged data as a function of the cleansed condition datum and the cleansed measured downhole conditions using a downhole machine learning model. The memory instructs the processor to generate a predicted downhole condition as a function of the flagged data.
Abstract:
A locomotive consist includes a first locomotive unit that receives a power command from a throttle signal or a dynamic brake signal from MU trainlines, a second locomotive unit with an energy storage system electrically connected to one or more second unit traction motors, and a hybrid control system on the first locomotive unit. The hybrid control system intercepts the throttle signal or the dynamic brake signal from the MU trainlines, calculates first and second alternate power commands for the first and second locomotive units, respectively, that when added together equal the power command received on the MU trainlines, communicates the first power command to the first locomotive prime engine or dynamic braking system, and communicates the second power command to the second locomotive unit.
Abstract:
A heat exchanger includes: a housing; a working fluid inlet and a working fluid outlet in the housing through which a working fluid enters and exits the housing, respectively, wherein a working fluid flow path connects the working fluid inlet and the working fluid outlet; and a heat transfer medium inlet and a heat transfer medium outlet in the housing through which a heat transfer medium enters and exits the housing, respectively; wherein a heat transfer medium flow path connects the heat transfer medium inlet and the heat transfer medium outlet; further wherein the heat transfer medium flow path includes at least two distinct zones of operation including a radiation dominant zone and a conduction dominant zone.
Abstract:
A locomotive underframe CNG fuel storage system including: a crashworthy enclosure including a removable side panel and a permanent side panel welded into place; and at least one CNG cylinder module, wherein each CNG cylinder module includes a plurality of CNG cylinders stacked vertically, secured to a vertical wall, and separated by a horizontal plate, wherein the horizontal plate extends towards but does not contact the vertical wall when the vertical wall is planar and, further wherein, the horizontal plate supports the vertical wall from moving further out of plane when vertical axial weight causes the vertical wall for move out of plane towards the horizontal plate.
Abstract:
To mitigate the potential significant impact on our society due to the continued reliance on high-cost diesel hydrocarbon fuel and the implementation of increasingly strict emission controls, an apparatus is disclosed which provides the means for extracting additional heat from an internal combustion engine while providing the cooling needed to meet stricter emissions standards. The present disclosure describes an apparatus operating on a Rankine cycle for recovering waste heat energy from an internal combustion engine, the apparatus including a closed loop for a working fluid with a single shared low pressure condenser serving a pair of independent high pressure circuits each containing zero or more controlled or passive fluid splitters and mixers, one or more pressure pumps, one or more heat exchangers, and one or more expanders, and the means for controlling said apparatus.
