Abstract: A vapor provision system including a vapor generation chamber, a reservoir containing liquid, a vaporizer located in the vapor generation chamber and a liquid transport element arranged to transport liquid from the reservoir through an opening in a wall of the vapor generation chamber to the vaporizer, wherein the liquid transport element in the vapor generation chamber has a cross-sectional area which is greater than that of the opening, and wherein the liquid transport element in the vapor generation chamber abuts the wall surrounding the opening to help prevent leakage.

Abstract: An aerosol source for a vapor provision system includes a vapor-generating element; a reservoir for holding source liquid, the reservoir being bounded by a wall having an opening therein; and a liquid transport element including a first portion arranged to receive liquid from the reservoir via the opening, a second portion peripheral to the first portion, and a third portion arranged to deliver liquid from the first portion to the vapor-generating element; wherein at least part of the second portion is compressed against a section of the wall around the opening, in use, to provide a sealing effect around at least part of the first portion to promote movement of liquid towards the vapor-generating element.

Abstract: A set and release retainer valve assembly of an air brake system engages and releases an air brake while retaining a designated pressure within a brake cylinder. The pressure is retained within the brake cylinder to generate a higher brake cylinder pressure on a subsequent brake application and/or prevent movement of the vehicle system after release of the air brake system. The air brake is subsequently re-engaged to re-set the retaining valve assembly and exhaust the designated air pressure out of the brake cylinder, where the air brake of the vehicle system is released to permit the movement of the vehicle system after re-setting the retaining valve assembly.

Abstract: A brake health monitoring system and method measure pressures in different components of a brake system of a vehicle system during movement of the vehicle system. Two or more of the pressures that are measured in the different components are compared with each other to select a health monitoring mode. One or more allowable pressures are selected based on the health monitoring mode that is selected. A state of health of the brake system is determined by comparing one or more of the pressures that is measured with the one or more allowable pressures that are selected.

Abstract: Systems and methods for coverage analysis using context information are described. The systems and methods can be used to obtain program code and test information for testing the program code, the test information associated with context information for providing context for testing the program code. Coverage information can be generated by testing the program code according to the test information. A first association can be generated between the context information and the test information. A second association can be generated between the context information and the program code. A third association can be generated between the coverage information and the test information. A subset of the coverage information can be determined based on the third association and a fourth association between the test information and the program code determined based on the first and second associations. An indication of the subset of the coverage information can be displayed.

Abstract: A brake monitoring system monitors pressures in a brake system of a vehicle system at different locations in the vehicle system. Decreases in the pressures are determined at two or more of the different locations. The times at which the decreases in the pressures occurred are determined. A location of interest of a leak in the brake system is determined by comparing the times at which the decreases in the pressures occurred.

Abstract: A gas supply apparatus with improved control is provided. The gas supply apparatus provides gas at an outlet junction. The apparatus includes a gas mixer for gasses from primary and secondary supplies to a given ratio. The apparatus also includes a gas reservoir supplied by the gas mixer. A tertiary supply valve is also included and connected in parallel with the reservoir. The tertiary supply valve is adapted to connect the outlet junction to a tertiary gas supply when gas is not being supplied to a mixer by the primary and/or secondary supply.

Abstract: A method for resistance training to arm and leg movement can include connecting a horizontally oriented raised weight base secured to a moveable sled in a spaced apart relationship, mounting a agility box, threading a first flexible and extendable one piece stretch cord through a plurality of aligned first upper rollers, securing a static non-extending stretch cord between the moveable sled and a subject, pulling on the first flexible and extendable one piece stretch cord connected to the moveable sled by the subject to receive a first load of resistance causing a physiological change to a targeted part of the subject and simultaneously receiving a second load of resistance to a targeted part of the subject while pulling the moveable sled with the static non-extendable stretch cord.

Abstract: The present invention comprises a novel sled training device generally consisting of a sled with vertically oriented pole for attaching, a detachable cuboidal structure that attaches to the sled and holds pulley systems with stretch cords running through them and then to the ankles and wrists of the user. A rope or stretch cord attaches to the front of the sled and runs to an attachment point on a harness worn by the user when the apparatus is configured to be pulled by the user. The apparatus may be configured to be pushed by the user by means of an attachment that connects to the vertically oriented pole for attaching weights, and which has padded structures to be pushed by the subject's shoulders and/or forehead. The detachable cuboidal structure may be removed from the sled and attached to any stationary structure for use without the sled.
